The existing method of audio-visual recognition has explored methods with ResNet and feature fusion. However, on the one hand, ResNet always occupies a large amount of memory resources, restricting the application in engineering. On the other hand, the feature merging also brings some interferences in a high noise environment. In order to solve the problems, we proposed an effective framework with bidirectional distillation. At first, in consideration of the good performance in extracting of features, we chose the light model, Efficientnet as our extractor of spatial features. Secondly, self-distillation was applied to learn more information from raw data. Finally, we proposed a bidirectional distillation in decision-level fusion. In more detail, our experimental results are based on a multi-model dataset from 24 volunteers. Eventually, the lipreading accuracy of our framework was increased by 2.3% compared with existing systems, and our framework made progress in audio-visual fusion in a high noise environment compared with the system of audio recognition without visual. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lipreading" title="lipreading">lipreading</a>, <a href="https://publications.waset.org/abstracts/search?q=audio-visual" title=" audio-visual"> audio-visual</a>, <a href="https://publications.waset.org/abstracts/search?q=Efficientnet" title=" Efficientnet"> Efficientnet</a>, <a href="https://publications.waset.org/abstracts/search?q=distillation" title=" distillation"> distillation</a> </p> <a href="https://publications.waset.org/abstracts/146625/audio-visual-recognition-based-on-effective-model-and-distillation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146625.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">134</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">149</span> Enhanced High-Temperature Strength of HfNbTaTiZrV Refractory High-Entropy Alloy via Al₂O₃ Reinforcement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bingjie%20Wang">Bingjie Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qianqian%20Qang"> Qianqian Qang</a>, <a href="https://publications.waset.org/abstracts/search?q=Nan%20Lu"> Nan Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiubing%20Liang"> Xiubing Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Baolong%20Shen"> Baolong Shen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Novel composites of HfNbTaTiZrV refractory high-entropy alloy (RHEA) reinforced with 0-5 vol.% Al₂O₃ particles have been synthesized by vacuum arc melting. The microstructure evolution, compressive mechanical properties at room and elevated temperatures, as well as strengthening mechanism of the composites, are analyzed. The HfNbTaTiZrV RHEA reinforced with 4 vol.% Al₂O₃ displays excellent phase stability at elevated temperatures. A superior compressive yield strength of 2700 MPa at room temperature, 1392 MPa at 800 °C, and 693 MPa at 1000 °C has been obtained for this composite. The improved yield strength results from multiple strengthening mechanisms caused by Al₂O₃ addition, including interstitial strengthening, grain boundary strengthening, and dispersion strengthening. Besides, the effects of interstitial strengthening increase with the temperature and is the main strengthening mechanism at elevated temperatures. These findings not only promote the development of oxide-reinforced RHEAs for challenging engineering applications but also provide guidelines for the design of light refractory materials with multiple strengthening mechanisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al%E2%82%82O%E2%82%83-reinforcement" title="Al₂O₃-reinforcement">Al₂O₃-reinforcement</a>, <a href="https://publications.waset.org/abstracts/search?q=HfNbTaTiZrV" title=" HfNbTaTiZrV"> HfNbTaTiZrV</a>, <a href="https://publications.waset.org/abstracts/search?q=refractory%20high-entropy%20alloy" title=" refractory high-entropy alloy"> refractory high-entropy alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=interstitial%20strengthening" title=" interstitial strengthening"> interstitial strengthening</a> </p> <a href="https://publications.waset.org/abstracts/158860/enhanced-high-temperature-strength-of-hfnbtatizrv-refractory-high-entropy-alloy-via-al2o3-reinforcement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158860.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">113</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">148</span> Improved 3D Structure Prediction of Beta-Barrel Membrane Proteins by Using Evolutionary Coupling Constraints, Reduced State Space and an Empirical Potential Function</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wei%20Tian">Wei Tian</a>, <a href="https://publications.waset.org/abstracts/search?q=Jie%20Liang"> Jie Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hammad%20Naveed"> Hammad Naveed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Beta-barrel membrane proteins are found in the outer membrane of gram-negative bacteria, mitochondria, and chloroplasts. They carry out diverse biological functions, including pore formation, membrane anchoring, enzyme activity, and bacterial virulence. In addition, beta-barrel membrane proteins increasingly serve as scaffolds for bacterial surface display and nanopore-based DNA sequencing. Due to difficulties in experimental structure determination, they are sparsely represented in the protein structure databank and computational methods can help to understand their biophysical principles. We have developed a novel computational method to predict the 3D structure of beta-barrel membrane proteins using evolutionary coupling (EC) constraints and a reduced state space. Combined with an empirical potential function, we can successfully predict strand register at > 80% accuracy for a set of 49 non-homologous proteins with known structures. This is a significant improvement from previous results using EC alone (44%) and using empirical potential function alone (73%). Our method is general and can be applied to genome-wide structural prediction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beta-barrel%20membrane%20proteins" title="beta-barrel membrane proteins">beta-barrel membrane proteins</a>, <a href="https://publications.waset.org/abstracts/search?q=structure%20prediction" title=" structure prediction"> structure prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=evolutionary%20constraints" title=" evolutionary constraints"> evolutionary constraints</a>, <a href="https://publications.waset.org/abstracts/search?q=reduced%20state%20space" title=" reduced state space"> reduced state space</a> </p> <a href="https://publications.waset.org/abstracts/40565/improved-3d-structure-prediction-of-beta-barrel-membrane-proteins-by-using-evolutionary-coupling-constraints-reduced-state-space-and-an-empirical-potential-function" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40565.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">618</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">147</span> Compared Psychophysiological Responses under Stress in Patients of Chronic Fatigue Syndrome and Depressive Disorder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fu-Chien%20Hung">Fu-Chien Hung</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi%E2%80%90Wen%20Liang"> Chi‐Wen Liang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: People who suffer from chronic fatigue syndrome (CFS) frequently complain about continuous tiredness, weakness or lack of strength, but without apparent organic etiology. The prevalence rate of the CFS is nearly from 3% to 20%, yet more than 80% go undiagnosed or misdiagnosed as depression. The biopsychosocial model has suggested the associations among the CFS, depressive syndrome, and stress. This study aimed to investigate the difference between individuals with the CFS and with the depressive syndrome on psychophysiological responses under stress. Method: There were 23 participants in the CFS group, 14 participants in the depression group, and 23 participants in the healthy control group. All of the participants first completed the measures of demographic data, CFS-related symptoms, daily life functioning, and depressive symptoms. The participants were then asked to perform a stressful cognitive task. The participants’ psychophysiological responses including the HR, BVP and SC were measured during the task. These indexes were used to assess the reactivity and recovery rates of the automatic nervous system. Results: The stress reactivity of the CFS and depression groups was not different from that of the healthy control group. However, the stress recovery rate of the CFS group was worse than that of the healthy control group. Conclusion: The results from this study suggest that the CFS is a syndrome which can be independent from the depressive syndrome, although the depressive syndrome may include fatigue syndrome. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chronic%20fatigue%20syndrome" title="chronic fatigue syndrome">chronic fatigue syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=depression" title=" depression"> depression</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20response" title=" stress response"> stress response</a>, <a href="https://publications.waset.org/abstracts/search?q=misdiagnosis" title=" misdiagnosis"> misdiagnosis</a> </p> <a href="https://publications.waset.org/abstracts/5129/compared-psychophysiological-responses-under-stress-in-patients-of-chronic-fatigue-syndrome-and-depressive-disorder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5129.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">457</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">146</span> Sense Environmental Hormones in Elementary School Teachers and Their in Service Learning Motivation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fu-Chi%20Chuang">Fu-Chi Chuang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Liang"> Yu-Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chang"> Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Der%20Wang"> Wen-Der Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Our environment has been contaminated by many artificial chemicals, such as plastics, pesticides. Many of them have hormone-like activity and are classified as 'environmental hormone (also named endocrine disruptors)'. These chemicals interfere with or mimic hormones have adverse effects that persist into adulthood. Environmental education is an important way to teach students to become engaged in real-world issues that transcend classroom walls. Elementary education is the first stage to perform environmental education and it is an important component to help students develop adequate environmental knowledge, attitudes, and behavior. However, elementary teachers' knowledge plays a critical role in this mission. Therefore, we use a questionnaire to survey the knowledge of environmental hormone of elementary school teachers and their learning motivation of the environmental hormone-regarding knowledge. We collected 218 questionnaires from Taiwanese elementary teachers and the results indicate around 73% of elementary teachers do not have enough knowledge about environmental hormones. Our results also reveal the in-service elementary teachers’ learning motivation of environmental hormones knowledge is positively enhanced once they realized their insufficient cognitive ability of environmental hormones. We believe our study will provide the powerful reference for Ministry of Education to set up the policy of environmental education to enrich all citizens sufficient knowledge of the effects of the environmental hormone on organisms, and further to enhance our correct environmental behaviors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elementary%20teacher" title="elementary teacher">elementary teacher</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20hormones" title=" environmental hormones"> environmental hormones</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20motivation" title=" learning motivation"> learning motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=questionnaire" title=" questionnaire"> questionnaire</a> </p> <a href="https://publications.waset.org/abstracts/104093/sense-environmental-hormones-in-elementary-school-teachers-and-their-in-service-learning-motivation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104093.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">313</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">145</span> Selecting Answers for Questions with Multiple Answer Choices in Arabic Question Answering Based on Textual Entailment Recognition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anes%20Enakoa">Anes Enakoa</a>, <a href="https://publications.waset.org/abstracts/search?q=Yawei%20Liang"> Yawei Liang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Question Answering (QA) system is one of the most important and demanding tasks in the field of Natural Language Processing (NLP). In QA systems, the answer generation task generates a list of candidate answers to the user's question, in which only one answer is correct. Answer selection is one of the main components of the QA, which is concerned with selecting the best answer choice from the candidate answers suggested by the system. However, the selection process can be very challenging especially in Arabic due to its particularities. To address this challenge, an approach is proposed to answer questions with multiple answer choices for Arabic QA systems based on Textual Entailment (TE) recognition. The developed approach employs a Support Vector Machine that considers lexical, semantic and syntactic features in order to recognize the entailment between the generated hypotheses (H) and the text (T). A set of experiments has been conducted for performance evaluation and the overall performance of the proposed method reached an accuracy of 67.5% with C@1 score of 80.46%. The obtained results are promising and demonstrate that the proposed method is effective for TE recognition task. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=information%20retrieval" title="information retrieval">information retrieval</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20language%20processing" title=" natural language processing"> natural language processing</a>, <a href="https://publications.waset.org/abstracts/search?q=question%20answering" title=" question answering"> question answering</a>, <a href="https://publications.waset.org/abstracts/search?q=textual%20entailment" title=" textual entailment"> textual entailment</a> </p> <a href="https://publications.waset.org/abstracts/103313/selecting-answers-for-questions-with-multiple-answer-choices-in-arabic-question-answering-based-on-textual-entailment-recognition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103313.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">144</span> Simulation Studies of Solid-Particle and Liquid-Drop Erosion of NiAl Alloy </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rong%20Liu">Rong Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuiying%20Chen"> Kuiying Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Ju%20Chen"> Ju Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Jingrong%20Zhao"> Jingrong Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming%20Liang"> Ming Liang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article presents modeling studies of NiAl alloy under solid-particle erosion and liquid-drop erosion. In the solid particle erosion simulation, attention is paid to the oxide scale thickness variation on the alloy in high-temperature erosion environments. The erosion damage is assumed to be deformation wear and cutting wear mechanisms, incorporating the influence of the oxide scale on the eroded surface; thus the instantaneous oxide thickness is the result of synergetic effect of erosion and oxidation. For liquid-drop erosion, special interest is in investigating the effects of drop velocity and drop size on the damage of the target surface. The models of impact stress wave, mean depth of penetration, and maximum depth of erosion rate (Max DER) are employed to develop various maps for NiAl alloy, including target thickness vs. drop size (diameter), rate of mean depth of penetration (MDRP) vs. drop impact velocity, and damage threshold velocity (DTV) vs. drop size. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=liquid-drop%20erosion" title="liquid-drop erosion">liquid-drop erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=NiAl%20alloy" title=" NiAl alloy"> NiAl alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=oxide%20scale%20thickness" title=" oxide scale thickness"> oxide scale thickness</a>, <a href="https://publications.waset.org/abstracts/search?q=solid-particle%20erosion" title=" solid-particle erosion"> solid-particle erosion</a> </p> <a href="https://publications.waset.org/abstracts/15516/simulation-studies-of-solid-particle-and-liquid-drop-erosion-of-nial-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15516.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">575</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">143</span> User Selections on Social Network Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20C.%20Liang">C.

Facebook and MSN have similar characteristics, including usefulness, ease-of-use, and a similar function, which is the exchanging of information with friends. Facebook outperforms MSN in both of these areas. However, the adoption of Facebook and abandonment of MSN have occurred for other reasons. Functions can be improved, but users’ willingness to use does not just depend on functionality. Flow status has been established to be crucial to users’ adoption of cyber applications and to affects users’ adoption of software applications. If users experience flow in using software application, they will enjoy using it frequently, and even change their preferred application from an old to this new one. However, no investigation has examined choice behavior related to switching from Facebook to MSN based on a consideration of flow experiences and functions. This investigation discusses the flow experiences and functions of social-networking applications.

These likely cause the lead-time provided by regional EEW systems before a destructive earthquake wave arrives to become null. On the other hand, an on-site EEW system can provide more lead-time at a region closer to an epicenter, since only seismic information of the target site is required. Instead of leveraging the information of several stations, the on-site system extracts some P-wave features from the first few seconds of vertical ground acceleration of a single station and performs a prediction of the oncoming earthquake intensity at the same station according to these features. Since seismometers could be triggered by non-earthquake events such as a passing of a truck or other human activities, to reduce the likelihood of false alarms, a seismometer was installed at three different locations on the same site and the performance of the EEW system for these three sensor locations were discussed. The results show that the location on the ground of the first floor of a school building maybe a good choice, since the false alarms could be reduced and the cost for installation and maintenance is the lowest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earthquake%20early%20warning" title="earthquake early warning">earthquake early warning</a>, <a href="https://publications.waset.org/abstracts/search?q=on-site" title=" on-site"> on-site</a>, <a href="https://publications.waset.org/abstracts/search?q=seismometer%20location" title=" seismometer location"> seismometer location</a>, <a href="https://publications.waset.org/abstracts/search?q=support%20vector%20machine" title=" support vector machine"> support vector machine</a> </p> <a href="https://publications.waset.org/abstracts/48504/performance-of-on-site-earthquake-early-warning-systems-for-different-sensor-locations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48504.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">243</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">141</span> Hsa-miR-326 Functions as a Tumor Suppressor in Non-Small Cell Lung Cancer through Targeting CCND1</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cheng-Cao%20Sun">Cheng-Cao Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Shu-Jun%20Li"> Shu-Jun Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Cuili%20Yang"> Cuili Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongyong%20Xi"> Yongyong Xi</a>, <a href="https://publications.waset.org/abstracts/search?q=Liang%20Wang"> Liang Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Feng%20Zhang"> Feng Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=De-Jia%20Li"> De-Jia Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hsa-miRNA-326 (miR-326) has recently been discovered having anticancer efficacy in different organs. However, the role of miR-326 on non-small cell lung cancer (NSCLC) is still ambiguous. In this study, we investigated the role of miR-326 on the development of NSCLC. The results indicated that miR-326 was significantly down-regulated in primary tumor tissues and very low levels were found in NSCLC cell lines. Ectopic expression of miR-326 in NSCLC cell lines significantly suppressed cell growth as evidenced by cell viability assay, colony formation assay and BrdU staining, through inhibition of cyclin D1, cyclin D2, CDK4, and up-regulation of p57(Kip2) and p21(Waf1/Cip1). In addition, miR-326 induced apoptosis, as indicated by concomitantly with up-regulation of key apoptosis protein cleaved caspase-3, and down-regulation of anti-apoptosis protein Bcl2. Moreover, miR-326 inhibited cellular migration and invasiveness through inhibition of matrix metalloproteinases (MMP)-7 and MMP-9. Further, oncogene CCND1 was revealed to be a putative target of miR-326, which was inversely correlated with miR-326 expression in NSCLC. Taken together, our results demonstrated that miR-326 played a pivotal role on NSCLC through inhibiting cell proliferation, migration, invasion, and promoting apoptosis by targeting oncogenic CCND1. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hsa-miRNA-326%20%28miR-326%29" title="hsa-miRNA-326 (miR-326)">hsa-miRNA-326 (miR-326)</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclin%20D1" title="cyclin D1">cyclin D1</a>, <a href="https://publications.waset.org/abstracts/search?q=non-small%20cell%20lung%20cancer%20%28NSCLC%29" title=" non-small cell lung cancer (NSCLC)"> non-small cell lung cancer (NSCLC)</a>, <a href="https://publications.waset.org/abstracts/search?q=proliferation" title=" proliferation"> proliferation</a>, <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title=" apoptosis"> apoptosis</a> </p> <a href="https://publications.waset.org/abstracts/41380/hsa-mir-326-functions-as-a-tumor-suppressor-in-non-small-cell-lung-cancer-through-targeting-ccnd1" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41380.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">306</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">140</span> Anti-Obesity Effect of Cordyceps militaris Fermented Black Rice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chih-Hung%20Liang">Chih-Hung Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung-Jung%20Chen"> Jung-Jung Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Shen-Shih%20Chiang"> Shen-Shih Chiang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Obesity is defined as abnormal or excessive fat accumulation that presents a risk to health, which are major risk factors for a number of chronic diseases, including diabetes, cardiovascular diseases and cancer. Cordyceps militaris (CM) is a well-known traditional medicine in Asian countries and a rich source of biologically active components. Black rice (Oryza sativa L.) is a special cultivar of rice that contains rich anthocyanins and regarded as a health-promoting food in China and other Eastern. The aim of this study was to investigate the anti-obesity effect of Cordyceps militaris fermented black rice (CB) on HFD-induced BALB/c mice model. The results indicated that administration of low and high dosage of CB powder significantly reduced the body weights (7.38% and 7.78%), body fat ratio (2.37% and 2.78%), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels compared to the HF group (p<0.05). Histopathological analysis showed that the score of fatty liver in HF group (5.0) was significantly higher than CB groups (2.1 and 3.6) (p<0.05). In conclusion, Cordyceps militaris fermented black rice can reduce the body weight via inhibition of the fat accumulation in liver and body and possess the anti-obesity potency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cordyceps%20militaris" title="Cordyceps militaris">Cordyceps militaris</a>, <a href="https://publications.waset.org/abstracts/search?q=black%20rice" title=" black rice"> black rice</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=HFD-induced%20mice" title=" HFD-induced mice"> HFD-induced mice</a> </p> <a href="https://publications.waset.org/abstracts/52203/anti-obesity-effect-of-cordyceps-militaris-fermented-black-rice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52203.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">310</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">139</span> Research on Road Openness in the Old Urban Residential District Based on Space Syntax: A Case Study on Kunming within the First Loop Road </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haoyang%20Liang">Haoyang Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Dandong%20Ge"> Dandong Ge</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the rapid development of Chinese cities, traffic congestion has become more and more serious. At the same time, there are many closed old residential area in Chinese cities, which seriously affect the connectivity of urban roads and reduce the density of urban road networks. After reopening the restricted old residential area, the internal roads in the original residential area were transformed into urban roads, which was of great help to alleviate traffic congestion. This paper uses the spatial syntactic theory to analyze the urban road network and compares the roads with the integration and connectivity degree to evaluate whether the opening of the roads in the residential areas can improve the urban traffic. Based on the road network system within the first loop road in Kunming, the Space Syntax evaluation model is established for status analysis. And comparative analysis method will be used to compare the change of the model before and after the road openness of the old urban residential district within the first-ring road in Kunming. Then it will pick out the areas which indicate a significant difference for the small dimensions model analysis. According to the analyzed results and traffic situation, the evaluation of road openness in the old urban residential district will be proposed to improve the urban residential districts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Space%20Syntax" title="Space Syntax">Space Syntax</a>, <a href="https://publications.waset.org/abstracts/search?q=Kunming" title=" Kunming"> Kunming</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20renovation" title=" urban renovation"> urban renovation</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20jam" title=" traffic jam"> traffic jam</a> </p> <a href="https://publications.waset.org/abstracts/112801/research-on-road-openness-in-the-old-urban-residential-district-based-on-space-syntax-a-case-study-on-kunming-within-the-first-loop-road" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112801.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">162</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">138</span> LncRNA NEAT1 Promotes NSCLC Progression through Acting as a ceRNA of miR-377-3p</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chengcao%20Sun">Chengcao Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Shujun%20Li"> Shujun Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Cuili%20Yang"> Cuili Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongyong%20Xi"> Yongyong Xi</a>, <a href="https://publications.waset.org/abstracts/search?q=Liang%20Wang"> Liang Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Feng%20Zhang"> Feng Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Dejia%20Li"> Dejia Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, the long non-coding RNA (lncRNA) NEAT1 has been identified as an oncogenic gene in multiple cancer types and elevated expression of NEAT1 was tightly linked to tumorigenesis and cancer progression. However, the molecular basis for this observation has not been characterized in progression of non-small cell lung cancer (NSCLC). In our studies, we identified NEAT1 was highly expressed in NSCLC patients and was a novel regulator of NSCLC progression. Patients whose tumors had high NEAT1 expression had a shorter overall survival than patients whose tumors had low NEAT1 expression. Further, NEAT1 significantly accelerates NSCLC cell growth and metastasis in vitro and tumor growth in vivo. Additionally, by using bioinformatics study and RNA pull down combined with luciferase reporter assays, we demonstrated that NEAT1 functioned as a competing endogenous RNA (ceRNA) for has-miR-377-3p, antagonized its functions and led to the de-repression of its endogenous targets E2F3, which was a core oncogene in promoting NSCLC progression. Taken together, these observations imply that the NEAT1 modulated the expression of E2F3 gene by acting as a competing endogenous RNA, which may build up the missing link between the regulatory miRNA network and NSCLC progression. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=long%20non-coding%20RNA%20NEAT1" title="long non-coding RNA NEAT1">long non-coding RNA NEAT1</a>, <a href="https://publications.waset.org/abstracts/search?q=hsa-miRNA-377-3p" title=" hsa-miRNA-377-3p"> hsa-miRNA-377-3p</a>, <a href="https://publications.waset.org/abstracts/search?q=E2F3" title=" E2F3"> E2F3</a>, <a href="https://publications.waset.org/abstracts/search?q=non-small%20cell%20lung%20cancer" title=" non-small cell lung cancer"> non-small cell lung cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=tumorigenesis" title=" tumorigenesis"> tumorigenesis</a> </p> <a href="https://publications.waset.org/abstracts/41377/lncrna-neat1-promotes-nsclc-progression-through-acting-as-a-cerna-of-mir-377-3p" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41377.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">369</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">137</span> Research of Control System for Space Intelligent Robot Based on Vision Servo</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Changchun%20Liang">Changchun Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaodong%20Zhang"> Xiaodong Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xin%20Liu"> Xin Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Pengfei%20Sun"> Pengfei Sun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Space intelligent robotic systems are expected to play an increasingly important role in the future. The robotic on-orbital service, whose key is the tracking and capturing technology, becomes research hot in recent years. In this paper, the authors propose a vision servo control system for target capturing. Robotic manipulator will be an intelligent robotic system with large-scale movement, functional agility, and autonomous ability, and it can be operated by astronauts in the space station or be controlled by the ground operator in the remote operation mode. To realize the autonomous movement and capture mission of SRM, a kind of autonomous programming strategy based on multi-camera vision fusion is designed and the selection principle of object visual position and orientation measurement information is defined for the better precision. Distributed control system hierarchy is designed and reliability is considering to guarantee the abilities of control system. At last, a ground experiment system is set up based on the concept of robotic control system. With that, the autonomous target capturing experiments are conducted. The experiment results validate the proposed algorithm, and demonstrates that the control system can fulfill the needs of function, real-time and reliability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=control%20system" title="control system">control system</a>, <a href="https://publications.waset.org/abstracts/search?q=on-orbital%20service" title=" on-orbital service"> on-orbital service</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20robot" title=" space robot"> space robot</a>, <a href="https://publications.waset.org/abstracts/search?q=vision%20servo" title=" vision servo"> vision servo</a> </p> <a href="https://publications.waset.org/abstracts/23241/research-of-control-system-for-space-intelligent-robot-based-on-vision-servo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23241.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">419</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">136</span> Factor Study Affecting Visual Awareness on Dynamic Object Monitoring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Terry%20Liang%20Khin%20Teo">Terry Liang Khin Teo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sun%20Woh%20Lye"> Sun Woh Lye</a>, <a href="https://publications.waset.org/abstracts/search?q=Kai%20Lun%20Brendon%20Goh"> Kai Lun Brendon Goh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As applied to dynamic monitoring situations, the prevailing approach to situation awareness (SA) assumes that the relevant areas of interest (AOI) be perceived before that information can be processed further to affect decision-making and, thereafter, action. It is not entirely clear whether this is the case. This study seeks to investigate the monitoring of dynamic objects through matching eye fixations with the relevant AOIs in boundary-crossing scenarios. By this definition, a match is where a fixation is registered on the AOI. While many factors may affect monitoring characteristics, traffic simulations were designed in this study to explore two factors, namely: the number of inbounds/outbound traffic transfers and the number of entry and/or exit points in a radar monitoring sector. These two factors were graded into five levels of difficulty ranging from low to high traffic flow numbers. Combined permutation in terms of levels of difficulty of these two factors yielded a total of thirty scenarios. Through this, results showed that changes in the traffic flow numbers on transfer resulted in greater variations having match limits ranging from 29%-100%, as compared to the number of sector entry/exit points of range limit from 80%-100%. The subsequent analysis is able to determine the type and combination of traffic scenarios where imperfect matching is likely to occur. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20traffic%20simulation" title="air traffic simulation">air traffic simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=eye-tracking" title=" eye-tracking"> eye-tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20monitoring" title=" visual monitoring"> visual monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=focus%20attention" title=" focus attention"> focus attention</a> </p> <a href="https://publications.waset.org/abstracts/155140/factor-study-affecting-visual-awareness-on-dynamic-object-monitoring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155140.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">57</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">135</span> Locating Speed Limit Signs for Highway Tunnel Entrance and Exit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Han%20Bai">Han Bai</a>, <a href="https://publications.waset.org/abstracts/search?q=Lemei%20Yu"> Lemei Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Tong%20Zhang"> Tong Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Doudou%20Xie"> Doudou Xie</a>, <a href="https://publications.waset.org/abstracts/search?q=Liang%20Zhao"> Liang Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The brightness changes at highway tunnel entrance and exit have an effect on the physical and psychological conditions of drivers.

Analyses the thermal simulation regarding 3D printed walls and solid brick wall by the way of the hot-box methods and the infrared technology, and the results were contrasted with theoretical calculation. The results show that the excellent thermodynamic performance of 3D printed concrete wall made it suitable as the partial materials for self-thermal insulation walls in residential buildings. The thermodynamic performance of 3D printed concrete walls depended on the density of materials, distribution of holes, and the filling materials. Decreasing the density of materials, increasing the number of holes or replacing the filling materials with foamed concrete could improve its thermodynamic performance significantly. The average of heat transfer coefficient and thermal inertia index of 3D printed steel slag powder concrete wall all better than the traditional solid brick wall with a thickness of 240mm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete" title="concrete">concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20printed%20walls" title=" 3D printed walls"> 3D printed walls</a>, <a href="https://publications.waset.org/abstracts/search?q=thermodynamic%20performance" title=" thermodynamic performance"> thermodynamic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20slag%20powder" title=" steel slag powder"> steel slag powder</a> </p> <a href="https://publications.waset.org/abstracts/92165/thermodynamic-performance-tests-for-3d-printed-steel-slag-powder-concrete-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92165.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">183</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">133</span> Autophagy Regulates Human Hepatocellular Carcinoma Tumorigenesis through Selective Degradation of Cyclin D1</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shan-Ying%20Wu">Shan-Ying Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheng-Hui%20Lan"> Sheng-Hui Lan</a>, <a href="https://publications.waset.org/abstracts/search?q=Xi-Zhang%20Lin"> Xi-Zhang Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ih-Jen%20Su"> Ih-Jen Su</a>, <a href="https://publications.waset.org/abstracts/search?q=Ting-Fen%20Tsai"> Ting-Fen Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Chia-Jui%20Yen"> Chia-Jui Yen</a>, <a href="https://publications.waset.org/abstracts/search?q=Tsung-Hsueh%20Lu"> Tsung-Hsueh Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Fu-Wen%20Liang"> Fu-Wen Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Huey-Jen%20Su"> Huey-Jen Su</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun-Li%20Su"> Chun-Li Su</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsiao-Sheng%20Liu"> Hsiao-Sheng Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In hepatocelluar carcinoma (HCC), dysregulated expression of cyclin D1 and impaired autophagy has been reported separately. However, the relationship between them has not been explored. In this study, we demonstrated that autophagy was inversely correlated with cyclin D1 expression in 147 paired HCC patient specimens. HCC specimen with highly expression of cyclin D1 shows correlation with poor overall survival rate. Furthermore, induction of autophagy by amiodarone (antiarrhythmic drug) in Hep 3B cells, cyclin D1 was recruited into autophagosomes demonstrated by immune-gold labeling of cyclin D1 after extraction of autophagosomes. We further demonstrated that autophagy suppresses Hep 3B cell proliferation, and further analysis revealed that cell cycle was arrested at G1 phase. The interaction between LC3 (maker of autophagy) and cyclin D1 was increased after autophagy induction. In addition, ubiquitinated-cyclin D1 was also increased after autophagy induction, which is selectively degraded by autophagosome through binding with SQSTM1/p62 (an adaptor protein). In vivo study showed that amiodarone induced autophagy suppresses liver tumor formation in xenograft mouse and orthotopic rat model through decreasing cyclin D1 expression and inhibition of cell proliferation. Altogether, we reveal a novel mechanism that ubiquitinated cyclin D1 degraded by autophagic pathway by p62 and amiodarone is a promising drug for targeting cyclin D1 in liver cancer therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autophagy" title="autophagy">autophagy</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclin%20D1" title=" cyclin D1"> cyclin D1</a>, <a href="https://publications.waset.org/abstracts/search?q=hepatocellular%20carcinoma" title=" hepatocellular carcinoma"> hepatocellular carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=amiodarone" title=" amiodarone"> amiodarone</a> </p> <a href="https://publications.waset.org/abstracts/56136/autophagy-regulates-human-hepatocellular-carcinoma-tumorigenesis-through-selective-degradation-of-cyclin-d1" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56136.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">295</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">132</span> Preparation of Silicon-Based Oxide Hollow Nanofibers Using Single-Nozzle Electrospinning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juiwen%20Liang">Juiwen Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Choliang%20Chung"> Choliang Chung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the silicon-base oxide nanofibers with hollow structure were prepared using single-nozzle electrospinning and heat treatment.

The nanoindented specimens are annealed at a temperature of either 160 °C or 210°C, respectively. The microstructures of the as-deposited and annealed samples are then examined via transmission electron microscopy (TEM). The results show that both the loading and the unloading regions of the load-displacement curve are smooth and continuous, which suggests that no debonding or cracking occurs during nanoindentation. In addition, the hardness and Young’s modulus of the Cu/Si thin films are found to vary with the nanoindentation depth, and have maximum values of 2.8 GPa and 143 GPa, respectively, at the maximum indentation depth of 2000 nm. The TEM observations show that the region of the Cu/Si film beneath the indenter undergoes a phase transformation during the indentation process. In the case of the as-deposited specimens, the indentation pressure induces a completely amorphous phase within the indentation zone. For the specimens annealed at a temperature of 160°C, the amorphous nature of the microstructure within the indented zone is maintained. However, for the specimens annealed at a higher temperature of 210°C, the indentation affected zone consists of a mixture of amorphous phase and nanocrystalline phase. Copper silicide (η-Cu3Si) precipitates are observed in all of the annealed specimens. The density of the η-Cu3Si precipitates is found to increase with an increasing annealing temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoindentation" title="nanoindentation">nanoindentation</a>, <a href="https://publications.waset.org/abstracts/search?q=Cu%2FSi%20thin%20films" title=" Cu/Si thin films"> Cu/Si thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructural%20evolution" title=" microstructural evolution"> microstructural evolution</a>, <a href="https://publications.waset.org/abstracts/search?q=annealing%20temperature" title=" annealing temperature"> annealing temperature</a> </p> <a href="https://publications.waset.org/abstracts/46615/effect-of-annealing-temperature-on-microstructural-evolution-of-nanoindented-cusi-thin-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46615.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">391</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">129</span> Laser Data Based Automatic Generation of Lane-Level Road Map for Intelligent Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zehai%20Yu">Zehai Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hui%20Zhu"> Hui Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Linglong%20Lin"> Linglong Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Huawei%20Liang"> Huawei Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Biao%20Yu"> Biao Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Weixin%20Huang"> Weixin Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the development of intelligent vehicle systems, a high-precision road map is increasingly needed in many aspects. The automatic lane lines extraction and modeling are the most essential steps for the generation of a precise lane-level road map. In this paper, an automatic lane-level road map generation system is proposed. To extract the road markings on the ground, the multi-region Otsu thresholding method is applied, which calculates the intensity value of laser data that maximizes the variance between background and road markings. The extracted road marking points are then projected to the raster image and clustered using a two-stage clustering algorithm. Lane lines are subsequently recognized from these clusters by the shape features of their minimum bounding rectangle. To ensure the storage efficiency of the map, the lane lines are approximated to cubic polynomial curves using a Bayesian estimation approach. The proposed lane-level road map generation system has been tested on urban and expressway conditions in Hefei, China. The experimental results on the datasets show that our method can achieve excellent extraction and clustering effect, and the fitted lines can reach a high position accuracy with an error of less than 10 cm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=curve%20fitting" title="curve fitting">curve fitting</a>, <a href="https://publications.waset.org/abstracts/search?q=lane-level%20road%20map" title=" lane-level road map"> lane-level road map</a>, <a href="https://publications.waset.org/abstracts/search?q=line%20recognition" title=" line recognition"> line recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-thresholding" title=" multi-thresholding"> multi-thresholding</a>, <a href="https://publications.waset.org/abstracts/search?q=two-stage%20clustering" title=" two-stage clustering"> two-stage clustering</a> </p> <a href="https://publications.waset.org/abstracts/132360/laser-data-based-automatic-generation-of-lane-level-road-map-for-intelligent-vehicles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132360.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">128</span> SPPO-Based Cation Exchange Membranes with a Positively Charged Layer for Cation Fractionation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noor%20Ul%20Afsar">Noor Ul Afsar</a>, <a href="https://publications.waset.org/abstracts/search?q=Wengen%20Ji"> Wengen Ji</a>, <a href="https://publications.waset.org/abstracts/search?q=Bin%20Wu"> Bin Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20A.%20Shehzad"> Muhammad A.

However, a technical approach is highly desired to construct MCPMs to obtain a high ionic flux and sustain perm-selectivity simultaneously. In the present work, the thickness of the quaternized poly (2, 6-dimethyl-1, 4-phenylene oxide) (QPPO) layer on the surface of the SPPO-PVA (SPVA) composite membrane was adjusted using a facile procedure to achieve high permselectivity without scarifying the ionic flux. The thickness of the selective layer was precisely controlled using various concentrations of the QPPO solution. By the introduction of the cationic layer on the SPVA membrane, the monovalent cation can be separated from the divalent cation by their difference in charge density. The influence of the selective barrier (thickness) endows MCPMs with high perm-selectivity up to 12.7 for 0.1 mol L⁻¹ Li⁺/Mg²⁺ system, which is very satisfactory for polymeric membranes. The fabricated membranes have low electrical resistance and high limiting current density (iₗᵢₘ). Keeping in view the ED results, the prepared membranes with selective surface layers could be a viable candidate for Li⁺ selective separation from divalent cation Mg²⁺. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=monovalent%20cation%20perm-selective%20membranes" title="monovalent cation perm-selective membranes">monovalent cation perm-selective membranes</a>, <a href="https://publications.waset.org/abstracts/search?q=cation%20fractionation" title=" cation fractionation"> cation fractionation</a>, <a href="https://publications.waset.org/abstracts/search?q=perm-selectivity" title=" perm-selectivity"> perm-selectivity</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20flux" title=" ionic flux"> ionic flux</a>, <a href="https://publications.waset.org/abstracts/search?q=electrodialysis" title=" electrodialysis"> electrodialysis</a> </p> <a href="https://publications.waset.org/abstracts/173307/sppo-based-cation-exchange-membranes-with-a-positively-charged-layer-for-cation-fractionation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173307.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">72</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">127</span> Synthesis and Surface Engineering of Lanthanide Nanoparticles for NIR Luminescence Imaging and Photodynamic Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syue-Liang%20Lin">Syue-Liang Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=C.%20Allen%20Chang"> C.

Concurrently, the development of NIR luminescence probes / imaging contrast agents has helped the understanding of the structural and functional properties of cells and animals. Photodynamic therapy (PDT) is used clinically to treat a wide range of medical conditions, but the therapeutic efficacy of general PDT for deeper tumor was limited by the penetration of excitation source. The tumor targeting biomedical nanomaterials UCNP@PS (upconversion nanoparticle conjugated with photosensitizer) for photodynamic therapy and near-infrared imaging of cancer will be developed in our study. Synthesis and characterization of biomedical nanomaterials were completed in this studies. The spectrum of UCNP was characterized by photoluminescence spectroscopy and the morphology was characterized by Transmission Electron Microscope (TEM). TEM and XRD analyses indicated that these nanoparticles are about 20~50 nm with hexagonal phase. NaYF₄:Ln³⁺ (Ln= Yb, Nd, Er) upconversion nanoparticles (UCNPs) with core / shell structure, synthesized by thermal decomposition method in 300°C, have the ability to emit visible light (upconversion: 540 nm, 660 nm) and near-infrared with longer wavelength (downconversion: NIR: 980 nm, 1525 nm) by absorbing 800 nm NIR laser.

It was concluded: (1) it mainly caused serious clogging problem and poor drainage performance in vertical drains of high content of fine soil particles and strong hydrophilic minerals in dredged mud, too fast loading rate at the early stage of vacuum preloading (namely rapidly reaching-80kPa) and too small characteristic opening size of the filter of the existed vertical drains; (2) it commonly reduced the drainage efficiency of drainage system, in turn weaken vacuum pressure in soils and soil improvement effect of the greater partial loss and friction loss of vacuum pressure caused by larger curvature of vertical drains and larger transfer resistance of vacuum pressure in horizontal drain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=newly%20dredged%20mud" title="newly dredged mud">newly dredged mud</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20well%20model%20experiments%20of%20vacuum%20preloading%20technology" title=" single well model experiments of vacuum preloading technology"> single well model experiments of vacuum preloading technology</a>, <a href="https://publications.waset.org/abstracts/search?q=poor%20drainage%20performance%20of%20vertical%20drains" title=" poor drainage performance of vertical drains"> poor drainage performance of vertical drains</a>, <a href="https://publications.waset.org/abstracts/search?q=poor%20soil%20improvement%20effect" title=" poor soil improvement effect"> poor soil improvement effect</a>, <a href="https://publications.waset.org/abstracts/search?q=causes%20analysis" title=" causes analysis"> causes analysis</a> </p> <a href="https://publications.waset.org/abstracts/2509/causes-analysis-of-vacuum-consolidation-failure-to-soft-foundation-filled-by-newly-dredged-mud" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2509.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">287</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">125</span> Parametric Study of a Solar-Heating-And-Cooling System with Hybrid Photovoltaic/Thermal Collectors in North China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruobing%20Liang">Ruobing Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jili%20Zhang"> Jili Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chao%20Zhou"> Chao Zhou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A solar-heating-and-cooling (SHC) system, consisting of a hybrid photovoltaic/ thermal collector array, a hot water storage tank, and an absorption chiller unit is designed and modeled to satisfy thermal loads (space heating, domestic hot water, and space cooling). The system is applied for Dalian, China, a location with cold climate conditions, where cooling demand is moderate, while space heating demand is slightly high. The study investigates the potential of a solar system installed and operated onsite in a detached single-family household to satisfy all necessary thermal loads. The hot water storage tank is also connected to an auxiliary heater (electric boiler) to supplement solar heating, when needed. The main purpose of the study is to model the overall system and contact a parametric study that will determine the optimum economic system performance in terms of design parameters. The system is compared, through a cost analysis, to an electric heat pump (EHP) system.

Although the coordination of light with phytohormone signals is crucial for plant growth and development, the molecular connection between light and brassinosteroid signaling during root soil penetration remains elusive. Here, we reveal that light-stabilized RACK1 couples a brassinosteroid signaling cascade to drive cell division in root meristems. RACK1 family scaffold proteins positively regulate light-induced the promotion of root elongation during soil penetration. Under the light condition, RACK1A interacts with both phyB and SPA1, then reinforces the phyB-SPA1 association to accumulate its abundance in roots. In response to brassinosteroid signals, RACK1A competes with BKI1 to attenuate the BRI1-BKI1 interaction, thereby leading to activating BRI1 actions in root development. Furthermore, RACK1A binds to BES1 to repress its DNA binding activity toward the target gene CYCD3;1. This ultimately allows to release the inhibition of CYCD3;1 transcription, and promotes cell division during root growth. Our study illustrates a new mechanistic model of how plants engage scaffold proteins in transducing light information to facilitate brassinosteroid signaling for root growth in the soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=root%20growth" title="root growth">root growth</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20division" title=" cell division"> cell division</a>, <a href="https://publications.waset.org/abstracts/search?q=light%20signaling" title=" light signaling"> light signaling</a>, <a href="https://publications.waset.org/abstracts/search?q=brassinosteroid%20signaling" title=" brassinosteroid signaling"> brassinosteroid signaling</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20penetration" title=" soil penetration"> soil penetration</a>, <a href="https://publications.waset.org/abstracts/search?q=scaffold%20protein" title=" scaffold protein"> scaffold protein</a>, <a href="https://publications.waset.org/abstracts/search?q=RACK1" title=" RACK1"> RACK1</a> </p> <a href="https://publications.waset.org/abstracts/171045/rack1-integrates-light-and-brassinosteroid-signaling-to-coordinate-cell-division-during-root-soil-penetration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171045.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">80</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">123</span> Sirt1 Promotes C2C12 Myoblast Cell Proliferation by Myostatin Signaling Pathway</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cuili%20Yang">Cuili Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chengcao%20Sun"> Chengcao Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruilin%20Xue"> Ruilin Xue</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongyong%20Xi"> Yongyong Xi</a>, <a href="https://publications.waset.org/abstracts/search?q=Liang%20Wang"> Liang Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Dejia%20Li"> Dejia Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Backgrounds: Previous studies showed that Sirt1 plays an important role in C2C12 myoblast cell proliferation, but the mechanism(s) involved in this process remains unclear. This work was undertaken to determine if Myostatin participates in the regulation of C2C12 proliferation by Sirt1. Methods: We administrated the Sirt1 activator resveratrol, inhibitor Nicotinamide (NAM) and Myostatin inhibitor SB431542 on C2C12 myoblast cells. Cell viability was evaluated by CCK8 assay. The expression of Sirt1 and MyoD were detected by qRT-PCR. Utilizing western blot to determinate the expression of myostatin, P107 and p-P107. Results: Our results showed that resveratrol promoted the proliferation of C2C12 myoblast cells, while NAM suppressed the proliferation of C2C12 myoblast cells; SB431542 promoted the proliferation of C2C12 myoblast cells and attenuated the inhibition effect of NAM on C2C12 myoblast cells proliferation; Resveratrol can significantly increase the expression of Sirt1 and MyoD, decrease the expression of Myostatin, while NAM can significantly down-regulate the expression of Sirt1, MyoD and the phosphorylation of P107(p-P107), but up-regulate the expression of Myostatin and the protein P107; SB431542 can significantly mitigate the effect of NAM on the expression of MyoD, P107, and p-P107. Conclusions: Taken together, these results indicate that Sirt1 promotes the proliferation of C2C12 myoblast cells via Myostatin signaling pathway. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sirt1" title="Sirt1">Sirt1</a>, <a href="https://publications.waset.org/abstracts/search?q=C2C12%20cells" title=" C2C12 cells"> C2C12 cells</a>, <a href="https://publications.waset.org/abstracts/search?q=proliferation" title=" proliferation"> proliferation</a>, <a href="https://publications.waset.org/abstracts/search?q=myostatin%20signaling%20pathway" title=" myostatin signaling pathway "> myostatin signaling pathway </a> </p> <a href="https://publications.waset.org/abstracts/21780/sirt1-promotes-c2c12-myoblast-cell-proliferation-by-myostatin-signaling-pathway" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21780.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">450</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">122</span> Augmented ADRC for Trajectory Tracking of a Novel Hydraulic Spherical Motion Mechanism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bin%20Bian">Bin Bian</a>, <a href="https://publications.waset.org/abstracts/search?q=Liang%20Wang"> Liang Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A hydraulic spherical motion mechanism (HSMM) is proposed. Unlike traditional systems using serial or parallel mechanisms for multi-DOF rotations, the HSMM is capable of implementing continuous 2-DOF rotational motions in a single joint without the intermediate transmission mechanisms. It has some advantages of compact structure, low inertia and high stiffness. However, as HSMM is a nonlinear and multivariable system, it is very complicate to realize accuracy control. Therefore, an augmented active disturbance rejection controller (ADRC) is proposed in this paper. Compared with the traditional PD control method, three compensation items, i.e., dynamics compensation term, disturbance compensation term and nonlinear error elimination term, are added into the proposed algorithm to improve the control performance. The ADRC algorithm aims at offsetting the effects of external disturbance and realizing accurate control. Euler angles are applied to describe the orientation of rotor. Lagrange equations are utilized to establish the dynamic model of the HSMM. The stability of this algorithm is validated with detailed derivation. Simulation model is formulated in Matlab/Simulink. The results show that the proposed control algorithm has better competence of trajectory tracking in the presence of uncertainties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20spherical%20motion%20mechanism" title="hydraulic spherical motion mechanism">hydraulic spherical motion mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20model" title=" dynamic model"> dynamic model</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20disturbance%20rejection%20control" title=" active disturbance rejection control"> active disturbance rejection control</a>, <a href="https://publications.waset.org/abstracts/search?q=trajectory%20tracking" title=" trajectory tracking"> trajectory tracking</a> </p> <a href="https://publications.waset.org/abstracts/126959/augmented-adrc-for-trajectory-tracking-of-a-novel-hydraulic-spherical-motion-mechanism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126959.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">105</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">121</span> Effect of the Drawbar Force on the Dynamic Characteristics of a Spindle-Tool Holder System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jui-Pui%20Hung">Jui-Pui Hung</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Sheng%20Lai"> Yu-Sheng Lai</a>, <a href="https://publications.waset.org/abstracts/search?q=Tzuo-Liang%20Luo"> Tzuo-Liang Luo</a>, <a href="https://publications.waset.org/abstracts/search?q=Kung-Da%20Wu"> Kung-Da Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yun-Ji%20Zhan"> Yun-Ji Zhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presented the investigation of the influence of the tool holder interface stiffness on the dynamic characteristics of a spindle tool system. The interface stiffness was produced by drawbar force on the tool holder, which tends to affect the spindle dynamics. In order to assess the influence of interface stiffness on the vibration characteristic of spindle unit, we first created a three dimensional finite element model of a high speed spindle system integrated with tool holder. The key point for the creation of FEM model is the modeling of the rolling interface within the angular contact bearings and the tool holder interface. The former can be simulated by a introducing a series of spring elements between inner and outer rings. The contact stiffness was calculated according to Hertz contact theory and the preload applied on the bearings. The interface stiffness of the tool holder was identified through the experimental measurement and finite element modal analysis. Current results show that the dynamic stiffness was greatly influenced by the tool holder system. In addition, variations of modal damping, static stiffness and dynamic stiffness of the spindle tool system were greatly determined by the interface stiffness of the tool holder which was in turn dependent on the draw bar force applied on the tool holder. Overall, this study demonstrates that identification of the interface characteristics of spindle tool holder is of very importance for the refinement of the spindle tooling system to achieve the optimum machining performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20stiffness" title="dynamic stiffness">dynamic
