As a results, Dodd-Frank Act has passed and aims '(1) to promote the financial stability of the United States by improving accountability and transparency in the financial system, to end "too big to fail", (2) to protect the American taxpayer by ending bailouts, (3) to protect consumers from abusive financial services practices, and for other purposes.' The enactment of Dodd-Frank Act, in part, intended to significantly influence accountability on executive compensation especially for the financial institutions. This paper empirically investigates the changes in Financial CEOs’ compensation since the Financial Crisis of 2008. Our findings show that in the post- Financial Crisis period financial leverage is significant factor influencing the CEOs’ total compensation. In addition market based performance such as stock price and market-to-book ratio shows significant positive relationship with CEO compensation. This change can be interpreted an attempt to reduce opportunistic behavior of top executives after the financial crisis and the enactment of the Dodd-Frank Act. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=financial%20CEO%20compensation" title="financial CEO compensation">financial CEO compensation</a>, <a href="https://publications.waset.org/abstracts/search?q=firm%20performance" title=" firm performance"> firm performance</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20crisis%20of%202008" title=" financial crisis of 2008"> financial crisis of 2008</a>, <a href="https://publications.waset.org/abstracts/search?q=dodd-frank%20act" title=" dodd-frank act"> dodd-frank act</a> </p> <a href="https://publications.waset.org/abstracts/2662/an-empirical-examination-of-the-determinant-of-the-financial-ceos-compensation-for-the-post-financial-crisis-period" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2662.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">522</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">530</span> Comparison of FASTMAP and B0 Field Map Shimming for 4T MRI</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohan%20L.%20Jayatiake">Mohan L.

However, local susceptibility variations can lead to field inhomogeneities that cause artifacts such as image distortion and signal loss. The effects of local susceptibility variation notoriously increase with magnetic field strength. Active shimming improves homogeneity by applying corrective fields generated from shim coils, but requires calculation of optimal current for each shim coil. FASTMAP (fast automatic shimming technique by mapping along projections) is an effective technique for finding optimal currents works well at high-field, but is restricted to shimming spherical regions of interest. The 3D gradient-echo pulse sequence was modified to reduce sensitivity to eddy currents and used to obtain susceptibility field maps at 4T. Measured fields were projected onto first-and second-order spherical harmonic functions corresponding to shim hardware. A spherical phantom was used to calibrate the shim currents. Susceptibility maps of a volunteer’s brain with and without FASTMAP shimming were obtained. Simulations indicate that optimal shim currents derived from the field map may provide better overall shimming of the human brain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shimming" title="shimming">shimming</a>, <a href="https://publications.waset.org/abstracts/search?q=high-field" title=" high-field"> high-field</a>, <a href="https://publications.waset.org/abstracts/search?q=active" title=" active"> active</a>, <a href="https://publications.waset.org/abstracts/search?q=passive" title=" passive"> passive</a> </p> <a href="https://publications.waset.org/abstracts/33673/comparison-of-fastmap-and-b0-field-map-shimming-for-4t-mri" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33673.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">509</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">529</span> Comparing Image Processing and AI Techniques for Disease Detection in Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luiz%20Daniel%20Garay%20Trindade">Luiz Daniel Garay Trindade</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20De%20Freitas%20Valle%20Neto"> Antonio De Freitas Valle Neto</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabio%20Paulo%20Basso"> Fabio Paulo Basso</a>, <a href="https://publications.waset.org/abstracts/search?q=Elder%20De%20Macedo%20Rodrigues"> Elder De Macedo Rodrigues</a>, <a href="https://publications.waset.org/abstracts/search?q=Maicon%20Bernardino"> Maicon Bernardino</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Welfer"> Daniel Welfer</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Muller"> Daniel Muller</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Agriculture plays an important role in society since it is one of the main sources of food in the world. To help the production and yield of crops, precision agriculture makes use of technologies aiming at improving productivity and quality of agricultural commodities. One of the problems hampering quality of agricultural production is the disease affecting crops. Failure in detecting diseases in a short period of time can result in small or big damages to production, causing financial losses to farmers. In order to provide a map of the contributions destined to the early detection of plant diseases and a comparison of the accuracy of the selected studies, a systematic literature review of the literature was performed, showing techniques for digital image processing and neural networks. We found 35 interesting tool support alternatives to detect disease in 19 plants. Our comparison of these studies resulted in an overall average accuracy of 87.45%, with two studies very closer to obtain 100%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pattern%20recognition" title="pattern recognition">pattern recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=precision%20agriculture" title=" precision agriculture"> precision agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20farming" title=" smart farming"> smart farming</a>, <a href="https://publications.waset.org/abstracts/search?q=agricultural%20automation" title=" agricultural automation"> agricultural automation</a> </p> <a href="https://publications.waset.org/abstracts/129444/comparing-image-processing-and-ai-techniques-for-disease-detection-in-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129444.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">379</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">528</span> Obsession of Time and the New Musical Ontologies. The Concert for Saxophone, Daniel Kientzy and Orchestra by Myriam Marbe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dutica%20Luminita">Dutica Luminita</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For the music composer Myriam Marbe the musical time and memory represent 2 (complementary) phenomena with conclusive impact on the settlement of new musical ontologies. Summarizing the most important achievements of the contemporary techniques of composition, her vision on the microform presented in The Concert for Daniel Kientzy, saxophone and orchestra transcends the linear and unidirectional time in favour of a flexible, multi-vectorial speech with spiral developments, where the sound substance is auto(re)generated by analogy with the fundamental processes of the memory. The conceptual model is of an archetypal essence, the music composer being concerned with identifying the mechanisms of the creation process, especially of those specific to the collective creation (of oral tradition). Hence the spontaneity of expression, improvisation tint, free rhythm, micro-interval intonation, coloristic-timbral universe dominated by multiphonics and unique sound effects. Hence the atmosphere of ritual, however purged by the primary connotations and reprojected into a wonderful spectacular space. The Concert is a work of artistic maturity and enforces respect, among others, by the timbral diversity of the three species of saxophone required by the music composer (baritone, sopranino and alt), in Part III Daniel Kientzy shows the performance of playing two saxophones concomitantly. The score of the music composer Myriam Marbe contains a deeply spiritualized music, full or archetypal symbols, a music whose drama suggests a real cinematographic movement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=archetype" title="archetype">archetype</a>, <a href="https://publications.waset.org/abstracts/search?q=chronogenesis" title=" chronogenesis"> chronogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=concert" title=" concert"> concert</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphonics" title=" multiphonics"> multiphonics</a> </p> <a href="https://publications.waset.org/abstracts/29047/obsession-of-time-and-the-new-musical-ontologies-the-concert-for-saxophone-daniel-kientzy-and-orchestra-by-myriam-marbe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29047.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">543</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">527</span> Fear of Isolation, Online Efficacy, and Selective Exposure in Online Political Discourse</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyujin%20Shim">Kyujin Shim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study explores how individual motivations in political psychology will lead to political expression and online discourse, and how those online political discourses result in individuals’ exposure to extreme/ personally-entertaining/ disinhibiting content.

It is generally accepted that vibration issues result from poor equipment installation. We had a water injection pump tested in the factory and exceeded the pump the vibration limit. Once the pump was brought to the site, its half-size shim plates were replaced with full-size shims plates that drastically reduced the vibration. In this study, vibration data was recorded for several similar motors run at the same and different speeds. The vibration values were recorded -for two and a half hours- and the vibration readings were analyzed to determine when the readings became consistent. This was as well supported by recording the audio noises produced by some machines seeking a relationship between changes in machine noises and machine abnormalities, such as vibration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vibration" title="vibration">vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=noise" title=" noise"> noise</a>, <a href="https://publications.waset.org/abstracts/search?q=installation" title=" installation"> installation</a>, <a href="https://publications.waset.org/abstracts/search?q=machine" title=" machine"> machine</a> </p> <a href="https://publications.waset.org/abstracts/149998/early-installation-effect-on-the-machines-generated-vibration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149998.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">525</span> Tensile Test of Corroded Strand and Maintenance of Corroded Prestressed Concrete Girders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeon%20Chi-Ho">Jeon Chi-Ho</a>, <a href="https://publications.waset.org/abstracts/search?q=Lee%20Jae-Bin"> Lee Jae-Bin</a>, <a href="https://publications.waset.org/abstracts/search?q=Shim%20Chang-Su"> Shim Chang-Su</a> </p> <p class="card-text"><strong>Abstract:</strong></p> National bridge inventory in Korea shows that the number of old prestressed concrete (PSC) bridgeover 30 years of service life is rapidly increasing. Recently tendon corrosion is one of the most critical issues in the maintenance of PSC bridges. In this paper, mechanical properties of corroded strands, which were removed from old bridges, were evaluated using tensile test. In the result, the equations to express the mechanical behavior of corroded strand were derived and compared to existing equation. For the decision of tendon replacement, it is necessary to evaluate the effect of corrosion level on strength and ductility of the structure.

As a result, the HEAVENS model considering not only the functional safety of the vehicle but also the security has been suggested. However, the HEAVENS model only presents a simple process, and there are no detailed procedures and activities for each process, making it difficult to apply it to the actual vehicle security vulnerability check. In this paper, we propose an automated attack database that systematically summarizes attack vectors, attack types, and vulnerable vehicle models to prepare for various car hacking attacks, and data flow diagrams that can detect various vulnerabilities and suggest a way to materialize the HEAVENS model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automotive%20security" title="automotive security">automotive security</a>, <a href="https://publications.waset.org/abstracts/search?q=HEAVENS" title=" HEAVENS"> HEAVENS</a>, <a href="https://publications.waset.org/abstracts/search?q=car%20hacking" title=" car hacking"> car hacking</a>, <a href="https://publications.waset.org/abstracts/search?q=security%20model" title=" security model"> security model</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20security" title=" information security"> information security</a> </p> <a href="https://publications.waset.org/abstracts/84442/a-study-on-automotive-attack-database-and-data-flow-diagram-for-concretization-of-heavens-a-car-security-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84442.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">362</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">523</span> Application of Soft Systems Methodology in Solving Disaster Emergency Logistics Problems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alhasan%20Hakami">Alhasan Hakami</a>, <a href="https://publications.waset.org/abstracts/search?q=Arun%20Kumar"> Arun Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20J.%20Shim"> Sung J.

These large-scale disasters caused huge casualties and losses. In addition, inefficient disaster response operations also caused the second wave of casualties and losses, and expanded the damage. Effective disaster management can be used to respond to the chaotic situation, and reduce the damage. However, some inefficient disaster response operations are still used. Therefore, this case study chose the 921 earthquakes for analysing disaster emergency logistics problems and proposed the Soft Systems Methodology (SSM) to solve disaster emergency logistics problems. Moreover, it analyses the effect of human factors on system operation, and suggests a solution to improve the system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soft%20systems%20methodology" title="soft systems methodology">soft systems methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency%20logistics" title=" emergency logistics"> emergency logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquakes" title=" earthquakes"> earthquakes</a>, <a href="https://publications.waset.org/abstracts/search?q=Japan" title=" Japan"> Japan</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20operation" title=" system operation "> system operation </a> </p> <a href="https://publications.waset.org/abstracts/1428/application-of-soft-systems-methodology-in-solving-disaster-emergency-logistics-problems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1428.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">440</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">522</span> Intra-miR-ExploreR, a Novel Bioinformatics Platform for Integrated Discovery of MiRNA:mRNA Gene Regulatory Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Surajit%20Bhattacharya">Surajit Bhattacharya</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Veltri"> Daniel Veltri</a>, <a href="https://publications.waset.org/abstracts/search?q=Atit%20A.%20Patel"> Atit A.

To address this knowledge gap, we have developed a novel tool in R, Intra-miR-ExploreR, that facilitates integrated discovery of miRNA targets by incorporating target databases and novel target prediction algorithms, using statistical methods including Pearson and Distance Correlation on microarray data, to arrive at high confidence intragenic miRNA target predictions. We have explored the efficacy of this tool using Drosophila melanogaster as a model organism for bioinformatics analyses and functional validation. A number of putative targets were obtained which were also validated using qRT-PCR analysis. Additional features of the tool include downloadable text files containing GO analysis from DAVID and Pubmed links of literature related to gene sets. Moreover, we are constructing interaction maps of intragenic miRNAs, using both micro array and RNA-seq data, focusing on neural tissues to uncover regulatory codes via which these molecules regulate gene expression to direct cellular development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=miRNA" title="miRNA">miRNA</a>, <a href="https://publications.waset.org/abstracts/search?q=miRNA%3AmRNA%20target%20prediction" title=" miRNA:mRNA target prediction"> miRNA:mRNA target prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20methods" title=" statistical methods"> statistical methods</a>, <a href="https://publications.waset.org/abstracts/search?q=miRNA%3AmRNA%20interaction%20network" title=" miRNA:mRNA interaction network"> miRNA:mRNA interaction network</a> </p> <a href="https://publications.waset.org/abstracts/27427/intra-mir-explorer-a-novel-bioinformatics-platform-for-integrated-discovery-of-mirnamrna-gene-regulatory-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27427.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">510</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">521</span> Inhibitory Effects of Ambrosia trifida L. on the Development of Root Hairs and Protein Patterns of Radicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ji-Hyon%20Kil">Ji-Hyon Kil</a>, <a href="https://publications.waset.org/abstracts/search?q=Kew-Cheol%20Shim"> Kew-Cheol Shim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyoung-Ae%20Park"> Kyoung-Ae Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyoungho%20Kim"> Kyoungho Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ambrosia trifida L. is designated as invasive alien species by the Act on the Conservation and Use of Biodiversity by the Ministry of Environment, Korea.

In this way, it is possible to grasp the correlation between various design elements, which was difficult to grasp, and to reflect this in the design result. In architecture, there is an attempt to predict the performance, which is difficult to grasp in the past, by finding the correlation among multiple factors mainly through machine learning. In architectural design area, some attempts to predict the performance affected by various factors have been tried. With machine learning, it is possible to quickly predict performance. The aim of this study is to propose a model that predicts performance according to the block arrangement of apartment housing through machine learning and the design alternative which satisfies the performance such as the daylight hours in the most similar form to the alternative proposed by the designer. Through this study, a designer can proceed with the design considering various design alternatives and accurate performances quickly from the early design stage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apartment%20housing" title="apartment housing">apartment housing</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=multi-objective%20optimization" title=" multi-objective optimization"> multi-objective optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20prediction" title=" performance prediction"> performance prediction</a> </p> <a href="https://publications.waset.org/abstracts/80644/a-study-on-performance-prediction-in-early-design-stage-of-apartment-housing-using-machine-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80644.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">481</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">516</span> Secondary Science Teachers' Views about Purposes of Practical Works in School Science</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kew-Cheol%20Shim">Kew-Cheol Shim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Hwan%20Moon"> Sung-Hwan Moon</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji-Hyon%20Kil"> Ji-Hyon Kil</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyoungho%20Kim"> Kyoungho Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper was to examine views of secondary school science teachers about purposes to use practical works in school science.

Most previous work focuses on using artificial intelligence (AI) to predict transplant success or failure outcomes. In this work, we focused on predicting de novo malignancy after liver transplantation using AI. We chose the patients that had malignancy after liver transplantation with no history of malignancy pre-transplant. Their donors were cancer-free as well. We analyzed 254,200 patient profiles with post-transplant malignancy from the US Organ Procurement and Transplantation Network (OPTN).

Aquafaba) has been used as an important and cost-effective alternative to eggs in gluten-free, vegan cooking and baking applications. The aquafaba (AQ) is primarily due to its excellent ability to stabilize foams and emulsions in foods. However, the functional ingredients of this excellent AQ are usually discarded with the compound release. This study developed a high-functional food material, AQ, using functional soybean AQ that has not been studied in Korea. A zero-waste and cost-effective hybrid process were used to produce oil emulsifiers from Korean soybeans. The treatment technique was implemented using a small number of efficient steps. Aquafaba from Backtae had the best emulsion properties (92%) and has the potential to produce more stable food oil emulsions. Therefore, this study is expected to be utilized in the development of the first gluten-free, vegan product for vegetarians and consumers with animal protein allergies, utilizing wastewater from cooked soybeans as a source of plant protein that can replace animal protein. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aquafaba" title="aquafaba">aquafaba</a>, <a href="https://publications.waset.org/abstracts/search?q=soybean" title=" soybean"> soybean</a>, <a href="https://publications.waset.org/abstracts/search?q=chickpea" title=" chickpea"> chickpea</a>, <a href="https://publications.waset.org/abstracts/search?q=emulsifiers" title=" emulsifiers"> emulsifiers</a>, <a href="https://publications.waset.org/abstracts/search?q=egg%20replacer" title=" egg replacer"> egg replacer</a>, <a href="https://publications.waset.org/abstracts/search?q=egg-free%20products" title=" egg-free products"> egg-free products</a> </p> <a href="https://publications.waset.org/abstracts/142569/aquafaba-derived-from-korean-soybean-cultivars-a-novel-vegan-egg-replacer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142569.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">177</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">512</span> Effect of the Cross-Sectional Geometry on Heat Transfer and Particle Motion of Circulating Fluidized Bed Riser for CO2 Capture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seungyeong%20Choi">Seungyeong Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Namkyu%20Lee"> Namkyu Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Il%20Shim"> Dong Il Shim</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Mun%20Lee"> Young Mun Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Ki%20Park"> Yong-Ki Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyung%20Hee%20Cho"> Hyung Hee Cho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Effect of the cross-sectional geometry on heat transfer and particle motion of circulating fluidized bed riser for CO<sub>2</sub> capture was investigated.

They have a high demand for processes to be analyzed, whose decisions must be grounded on severity laws. Despite the existing large amount of processes, there are several cases reporting similar subjects. Thus, previous decisions on already analyzed processes can be a precedent for current processes that refer to similar topics. Identifying similar topics is an open, yet essential task for identifying similarities between several processes. Since the actual amount of topics is considerably large, it is tedious and error-prone to identify topics using a pure manual approach. This paper presents a tool based on Machine Learning and Natural Language Processing to assists in building a labeled dataset. The tool relies on Topic Modelling with Latent Dirichlet Allocation to find the topics underlying a document followed by Jensen Shannon distance metric to generate a probability of similarity between documents pairs. Furthermore, in a case study with a corpus of decisions of the Rio de Janeiro State Court of Accounts, it was noted that data pre-processing plays an essential role in modeling relevant topics. Also, the combination of topic modeling and a calculated distance metric over document represented among generated topics has been proved useful in helping to construct a labeled base of similar and non-similar document pairs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=courts%20of%20accounts" title="courts of accounts">courts of accounts</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20labelling" title=" data labelling"> data labelling</a>, <a href="https://publications.waset.org/abstracts/search?q=document%20similarity" title=" document similarity"> document similarity</a>, <a href="https://publications.waset.org/abstracts/search?q=topic%20modeling" title=" topic modeling"> topic modeling</a> </p> <a href="https://publications.waset.org/abstracts/121281/towards-law-data-labelling-using-topic-modelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121281.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">179</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">509</span> Policy Brief/Note of Philippine Health Issues: Human Rights Violations Committed on Healthcare Workers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Trina%20Isabel%20Santiago">Trina Isabel Santiago</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Chua"> Daniel Chua</a>, <a href="https://publications.waset.org/abstracts/search?q=Jumee%20Tayaban"> Jumee Tayaban</a>, <a href="https://publications.waset.org/abstracts/search?q=Joseph%20Daniel%20Timbol"> Joseph Daniel Timbol</a>, <a href="https://publications.waset.org/abstracts/search?q=Joshua%20Yanes"> Joshua Yanes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Numerous instances of human rights violations on healthcare workers have been reported during the COVID-19 pandemic in the Philippines. This brief aims to explore these civil and political rights violations and propose recommendations to address these. Our review shows that a wide range of civic and political human rights violations have been committed by individual citizens and government agencies on individual healthcare workers and health worker groups. These violations include discrimination, red-tagging, evictions, illegal arrests, and acts of violence ranging from chemical attacks to homicide. If left unchecked, these issues, compounded by the pandemic, may lead to the exacerbations of the pre-existing problems of the Philippine healthcare system. Despite all pre-existing reports by human rights groups and public media articles, there still seems to be a lack of government action to condemn and prevent these violations. The existence of government agencies which directly contribute to these violations with the lack of condemnation from other agencies further propagate the problem. Given these issues, this policy brief recommends the establishment of an interagency task force for the protection of human rights of healthcare workers as well as the expedited passing of current legislative bills towards the same goal. For more immediate action, we call for the establishment of a dedicated hotline for these incidents with adequate appointment and training of point persons, construction of clear guidelines, and closer collaboration between government agencies in being united against these issues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20rights%20violations" title="human rights violations">human rights violations</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare%20workers" title=" healthcare workers"> healthcare workers</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19%20pandemic" title=" COVID-19 pandemic"> COVID-19 pandemic</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippines" title=" Philippines"> Philippines</a> </p> <a href="https://publications.waset.org/abstracts/169601/policy-briefnote-of-philippine-health-issues-human-rights-violations-committed-on-healthcare-workers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169601.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">629</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">508</span> Ethical Consumers, The Myth or the Reality?: The Effects of Ethics in CSR on Corporate Authenticity and Pro-Firm Behaviours </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Shim">K.

With special attention to the two different types of CSR motives, business-oriented CSR motive and society-oriented motive, the current study empirically tests a theoretical model of a mediating role of corporate authenticity between perception of CSR motives and the consumers’ subsequent pro-firm behaviours. Results indicate significant mediation effects of corporate authenticity between perception of altruistic and societal CSR motives and consumers’ pro-firm behaviours. Unlike previous notions of the negative influence of self-interested motives on corporate authenticity, perceived strategic and business-oriented motives in CSR does not negatively affect the evalution of corporate authenticity when stakeholders have utilitarian ethical perspectives. Unlike the Korean participants, US participants are not willing to conduct pro-firm behaviors when they perceive strategic and business-oriented CSR motives.

The permutation used in the standard for symmetric cryptography (the AES), for example, is based on a special kind of inversion in GF(28). Although very close to APN (2-uniform), this permutation still contains one number 4 in its differential spectrum, which means that, rigorously, it must be classified as 4-uniform. This fact motivates the search for fully APN permutations in other domains of definition. The extremely high complexity associated to this kind of problem precludes an exhaustive search for an APN permutation with 256 elements to be performed without the support of a suitable mathematical structure. On the other hand, in principle, there is nothing to indicate which mathematically structured domains can effectively help the search, and it is necessary to test several domains. In this work, the search for APN permutations in rings ℤ2×ℤ2k is investigated. After a full, exhaustive search with k=2 and k=3, all possible APN permutations in those rings were recorded, together with their differential profiles. Some very promising heuristics in these cases were collected so that, when used as a basis to prune backtracking for the same search in ℤ2×ℤ8 (search space with size 16! ≅244), just a few tenths of a second were enough to produce an APN permutation in a single CPU. Those heuristics were empirically extrapolated so that they could be applied to a backtracking search for APNs over ℤ2×ℤ16 (search space with size 32! ≅2117). The best permutations found in this search were further refined through Simulated Annealing, with a definition of neighbors suitable to this domain. The best result produced with this scheme was a 3-uniform permutation over ℤ2×ℤ16 with only 24 values equal to 3 in the differential spectrum (all the other 968 values were less than or equal 2, as it should be the case for an APN permutation). Although far from being fully APN, this result is technically better than a 4-uniform permutation and demanded only a few seconds in a single CPU. This is a strong indication that the use of mathematically structured domains, like the rings described in this work, together with heuristics based on smaller cases, can lead to dramatic cuts in the computational resources involved in the complexity of the search for APN permutations in extremely large domains. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=APN%20permutations" title="APN permutations">APN permutations</a>, <a href="https://publications.waset.org/abstracts/search?q=heuristic%20searches" title=" heuristic searches"> heuristic searches</a>, <a href="https://publications.waset.org/abstracts/search?q=symmetric%20cryptography" title=" symmetric cryptography"> symmetric cryptography</a>, <a href="https://publications.waset.org/abstracts/search?q=S-box%20design" title=" S-box design"> S-box design</a> </p> <a href="https://publications.waset.org/abstracts/145556/search-for-apn-permutations-in-rings-2-2k" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145556.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">159</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">505</span> Mesoporous Carbon Sphere/Nickel Cobalt Sulfide Core-Shell Microspheres for Supercapacitor Electrode Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Charmaine%20Lamiel">Charmaine Lamiel</a>, <a href="https://publications.waset.org/abstracts/search?q=Van%20Hoa%20Nguyen"> Van Hoa Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Marjorie%20Baynosa"> Marjorie Baynosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Jin%20Shim"> Jae-Jin Shim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The depletion of non-renewable sources had led to the continuous development of various energy storage systems in order to cope with the world’s demand in energy.

Through this study, a cost-effective and facile synthesis of CS@Ni-Co-S as an active electrode showed favorable electrochemical performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20sphere" title="carbon sphere">carbon sphere</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical" title=" electrochemical"> electrochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrothermal" title=" hydrothermal"> hydrothermal</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel%20cobalt%20sulfide" title=" nickel cobalt sulfide"> nickel cobalt sulfide</a>, <a href="https://publications.waset.org/abstracts/search?q=supercapacitor" title=" supercapacitor"> supercapacitor</a> </p> <a href="https://publications.waset.org/abstracts/42922/mesoporous-carbon-spherenickel-cobalt-sulfide-core-shell-microspheres-for-supercapacitor-electrode-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42922.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">236</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">504</span> SAR and B₁ Considerations for Multi-Nuclear RF Body Coils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ria%20Forner">Ria Forner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Due to increases in the SNR at 7T and above, it becomes more favourable to make use of X-nuclear imaging. Integrated body coils tuned to 120MHz for 31P, 79MHz for 23Na, and 75 MHz for 13C at 7T were simulated with a human male, female, or child body model to assess strategies of use for metabolic MR imaging in the body. Methods: B1 and SAR efficiencies in the heart, liver, spleen, and kidneys were assessed using numerical simulations over the three frequencies with phase shimming. Results: B1+ efficiency is highly variable over the different organs, particularly for the highest frequency; however, local SAR efficiency remains relatively constant over the frequencies in all subjects. Although the optimal phase settings vary, one generic phase setting can be identified for each frequency at which the penalty in B1+ is at a max of 10%. Discussion: The simulations provide practical strategies for power optimization, B1 management, and maintaining safety. As expected, the B1 field is similar at 75MHz and 79MHz, but reduced at 120MHz. However, the B1 remains relatively constant when normalised by the square root of the peak local SAR. This is in contradiction to generalized SAR considerations of 1H MRI at different field strengths, which is defined by global SAR instead. Conclusion: Although the B1 decreases with frequency, SAR efficiency remains constant throughout the investigated frequency range. It is possible to shim the body coil to obtain a maximum of 10% extra B1+ in a specific organ in a body when compared to a generic setting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=birdcage" title="birdcage">birdcage</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-nuclear" title=" multi-nuclear"> multi-nuclear</a>, <a href="https://publications.waset.org/abstracts/search?q=B1%20shimming" title=" B1 shimming"> B1 shimming</a>, <a href="https://publications.waset.org/abstracts/search?q=7%20Tesla%20MRI" title=" 7 Tesla MRI"> 7 Tesla MRI</a>, <a href="https://publications.waset.org/abstracts/search?q=liver" title=" liver"> liver</a>, <a href="https://publications.waset.org/abstracts/search?q=kidneys" title=" kidneys"> kidneys</a>, <a href="https://publications.waset.org/abstracts/search?q=heart" title=" heart"> heart</a>, <a href="https://publications.waset.org/abstracts/search?q=spleen" title=" spleen"> spleen</a> </p> <a href="https://publications.waset.org/abstracts/183402/sar-and-b1-considerations-for-multi-nuclear-rf-body-coils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183402.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">67</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">503</span> Biological Activities of Flaxseed Peptides (Linusorbs)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Youn%20Young%20Shim">Youn Young Shim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji%20Hye%20Kim"> Ji Hye Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20Youl%20Cho"> Jae Youl Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20J.%20T.%20Reaney"> Martin J. T.

The flax plant synthesizes an array of biologically active cyclic peptides or linusorbs (LOs, a.k.a. cyclolinopeptides) from three or more ribosome-derived precursors. [1–9-NαC]-linusorb B3 and [1–9-NαC]-linusorb B2, suppress immunity, induce apoptosis in human epithelial cancer cell line (Calu-3) cells, and inhibit T-cell proliferation, but the mechanism of LOs action is unknown. Using gene expression analysis in nematode cultures and human cancer cell lines, we have observed that LOs exert their activity, in part, through induction of apoptosis. Specific LOs’ properties include: 1) distribution throughout the body after flaxseed consumption; 2) induce heat shock protein (HSP) 70A production as an indicator of stress and address the issue in Caenorhabditis elegans (exposure of nematode cultures to [1–9-NαC]-linusorb B3 induced a 30% increase in production of the HSP 70A protein); 3) induce apoptosis in Calu-3 cells; and 4) modulate regulatory genes in microarray analysis. These diverse activities indicate that LOs might induce apoptosis in cancer cells or act as versatile platforms to deliver a variety of biologically active molecules for cancer therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flaxseed" title="flaxseed">flaxseed</a>, <a href="https://publications.waset.org/abstracts/search?q=linusorb" title=" linusorb"> linusorb</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20peptide" title=" cyclic peptide"> cyclic peptide</a>, <a href="https://publications.waset.org/abstracts/search?q=orbitides" title=" orbitides"> orbitides</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20shock%20protein" title=" heat shock protein"> heat shock protein</a>, <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title=" apoptosis"> apoptosis</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-cancer" title=" anti-cancer"> anti-cancer</a> </p> <a href="https://publications.waset.org/abstracts/148070/biological-activities-of-flaxseed-peptides-linusorbs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148070.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">136</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">502</span> Trace Analysis of Genotoxic Impurity Pyridine in Sitagliptin Drug Material Using UHPLC-MS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bashar%20Al-Sabti">Bashar Al-Sabti</a>, <a href="https://publications.waset.org/abstracts/search?q=Jehad%20Harbali"> Jehad Harbali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Pyridine is a reactive base that might be used in preparing sitagliptin. International Agency for Research on Cancer classifies pyridine in group 2B; this classification means that pyridine is possibly carcinogenic to humans. Therefore, pyridine should be monitored at the allowed limit in sitagliptin pharmaceutical ingredients. Objective: The aim of this study was to develop a novel ultra high performance liquid chromatography mass spectrometry (UHPLC-MS) method to estimate the quantity of pyridine impurity in sitagliptin pharmaceutical ingredients. Methods: The separation was performed on C8 shim-pack (150 mm X 4.6 mm, 5 µm) in reversed phase mode using a mobile phase of water-methanol-acetonitrile containing 4 mM ammonium acetate in gradient mode. Pyridine was detected by mass spectrometer using selected ionization monitoring mode at m/z = 80. The flow rate of the method was 0.75 mL/min. Results: The method showed excellent sensitivity with a quantitation limit of 1.5 ppm of pyridine relative to sitagliptin. The linearity of the method was excellent at the range of 1.5-22.5 ppm with a correlation coefficient of 0.9996. Recoveries values were between 93.59-103.55%. Conclusions: The results showed good linearity, precision, accuracy, sensitivity, selectivity, and robustness. The studied method was applied to test three batches of sitagliptin raw materials. Highlights: This method is useful for monitoring pyridine in sitagliptin during its synthesis and testing sitagliptin raw materials before using them in the production of pharmaceutical products. <p
