Remodelling of lymphatic vessels associated with a tumour is a key initial step in metastasis because it facilitates the entry of cancer cells into the lymphatic vasculature and their spread to lymph nodes and distant organs. Although it is clear that vascular endothelial growth factors (VEGFs), such as VEGF-C and VEGF-D, are key drivers of lymphatic remodelling, the means by which many signaling pathways in endothelial cells are coordinately regulated to drive growth and remodelling of lymphatics in cancer is not understood. We seek to understand the broader molecular mechanisms that control cancer metastasis, and are focusing on microRNAs, which coordinately regulate signaling pathways involved in complex biological responses in health and disease. Here, using small RNA sequencing, we found that a specific microRNA, miR-132, is upregulated in expression in lymphatic endothelial cells (LECs) in response to the lymphangiogenic growth factors. Interestingly, ectopic expression of miR-132 in LECs in vitro stimulated proliferation and tube formation of these cells. Moreover, miR-132 is expressed in lymphatic vessels of a subset of human breast tumours which were previously found to express high levels of VEGF-D by immunohistochemical analysis on tumour tissue microarrays. In order to dissect the complexity of regulation by miR-132 in lymphatic biology, we performed Argonaute HITS-CLIP, which led us to identify the miR-132-mRNA interactome in LECs. We found that this microRNA in LECs is involved in the control of many different pathways mainly involved in cell proliferation and regulation of the extracellular matrix and cell-cell junctions. We are now exploring the functional significance of miR-132 targets in the biology of LECs using biochemical techniques, functional in vitro cell assays and in vivo lymphangiogenesis assays. This project will ultimately define the molecular regulation of lymphatic remodelling by miR-132, and thereby identify potential therapeutic targets for drugs designed to restrict the growth and remodelling of tumour lymphatics resulting in metastatic spread. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=argonaute%20HITS-CLIP" title="argonaute HITS-CLIP">argonaute HITS-CLIP</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=lymphatic%20remodelling" title=" lymphatic remodelling"> lymphatic remodelling</a>, <a href="https://publications.waset.org/abstracts/search?q=miR-132" title=" miR-132"> miR-132</a>, <a href="https://publications.waset.org/abstracts/search?q=VEGF" title=" VEGF"> VEGF</a> </p> <a href="https://publications.waset.org/abstracts/110680/control-of-lymphatic-remodelling-by-mir-132" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110680.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">103</span> Characteristic of Ta Alloy Coating Films on Near-Net Shape with Different Current Densities Using MARC Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young%20Jun%20Lee">Young Jun Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae%20Hyuk%20Lee"> Tae Hyuk Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyoung%20Tae%20Park"> Kyoung Tae Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Hyeon%20Lee"> Jong Hyeon Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The harsh atmosphere of the sulfur-iodine process used for producing hydrogen requires better corrosion resistance and mechanical properties that is possible to obtain with pure tantalum. Ta-W alloy is superior to pure tantalum but is difficult to alloy due to its high melting temperature. In this study, substrates of near-net shape (Swagelok® tube ISSG8UT4) were coated with Ta-W using the multi-anode reactive alloy coating (MARC) process in molten salt (LiF-NaF-K2TaF7) at different current densities (1, 2 and 4mA/cm2). Ta-4W coating films of uniform coating thicknesses, without any entrapped salt, were successfully deposited on Swagelok tube by electrodeposition at 1 mA/cm2. The resulting coated film with a corrosion rate of less than 0.011 mm/year was attained in hydriodic acid at 160°C, and hardness up to 12.9 % stronger than pure tantalum coated film. The alloy coating films also contributed to significant enhancement of corrosion resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tantalum" title="tantalum">tantalum</a>, <a href="https://publications.waset.org/abstracts/search?q=tantalum%20alloy" title=" tantalum alloy"> tantalum alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=tungsten%20alloy" title=" tungsten alloy"> tungsten alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=electroplating" title=" electroplating"> electroplating</a> </p> <a href="https://publications.waset.org/abstracts/32956/characteristic-of-ta-alloy-coating-films-on-near-net-shape-with-different-current-densities-using-marc-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32956.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">422</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">102</span> Stability of Total Phenolic Concentration and Antioxidant Capacity of Extracts from Pomegranate Co-Products Subjected to In vitro Digestion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olaniyi%20Fawole">Olaniyi Fawole</a>, <a href="https://publications.waset.org/abstracts/search?q=Umezuruike%20Opara"> Umezuruike Opara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Co-products obtained from pomegranate juice processing contain high levels of polyphenols with potential high added values. From value-addition viewpoint, the aim of this study was to evaluate the stability of polyphenolic concentrations in pomegranate fruit co-products in different solvent extracts and assess the effect on the total antioxidant capacity using the FRAP, DPPH˙ and ABTS˙+ assays during simulated in vitro digestion. Pomegranate juice, marc and peel were extracted in water, 50% ethanol (50%EtOH) and absolute ethanol (100%EtOH) and analysed for total phenolic concentration (TPC), total flavonoids concentration (TFC) and total antioxidant capacity in DPPH˙, ABST˙+ and FRAP assays before and after in vitro digestion. Total phenolic concentration (TPC) and total flavonoid concentration (TFC) were in the order of peel > marc > juice throughout the in vitro digestion irrespective of the extraction solvents used. However, 50% ethanol extracted 1.1 to 12-fold more polyphenols than water and ethanol solvents depending on co-products. TPC and TFC increased significantly in gastric digests. In contrast, after the duodenal, polyphenolic concentrations decreased significantly (p < 0.05) compared to those obtained in gastric digests. Undigested samples and gastric digests showed strong and positive relationships between polyphenols and the antioxidant activities measured in DPPH, ABTS and FRAP assays, with correlation coefficients (r2) ranging between 0.930 – 0.990 whereas, the correlation between polyphenols (TPC and TFC) and radical cation scavenging activity (in ABTS) were moderately positive in duodenal digests. Findings from this study also showed that the concentration of pomegranate polyphenols and antioxidant thereof during in vitro gastro-intestinal digestion may not reflect the pre-digested phenolic concentration. Thus, this study highlights the need to provide biologically relevant information on antioxidants by providing data reflecting their stability and activity after in vitro digestion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=by-product" title="by-product">by-product</a>, <a href="https://publications.waset.org/abstracts/search?q=DPPH" title=" DPPH"> DPPH</a>, <a href="https://publications.waset.org/abstracts/search?q=polyphenols" title=" polyphenols"> polyphenols</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20addition" title=" value addition"> value addition</a> </p> <a href="https://publications.waset.org/abstracts/53803/stability-of-total-phenolic-concentration-and-antioxidant-capacity-of-extracts-from-pomegranate-co-products-subjected-to-in-vitro-digestion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53803.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">330</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">101</span> Net Neutrality and Asymmetric Platform Competition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Romain%20Lestage">Romain Lestage</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc%20Bourreau"> Marc Bourreau</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper we analyze the interplay between access to the last-mile network and net neutrality in the market for Internet access.

In this paper we describe a tracking approach that is only based on a 24 GHz radar sensor. While common radar signal processing loses much information, we make use of a track-before-detect filter to incorporate raw measurements. It is explained how the Range-Doppler spectrum can help to indicated pedestrians and stabilize tracking even in occultation scenarios compared to sensors in series. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radar" title="radar">radar</a>, <a href="https://publications.waset.org/abstracts/search?q=pedestrian%20detection" title=" pedestrian detection"> pedestrian detection</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20safety" title=" active safety"> active safety</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor" title=" sensor"> sensor</a> </p> <a href="https://publications.waset.org/abstracts/6539/detection-and-tracking-approach-using-an-automotive-radar-to-increase-active-pedestrian-safety" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6539.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">529</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">98</span> Identification of Configuration Space Singularities with Local Real Algebraic Geometry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marc%20Diesse">Marc Diesse</a>, <a href="https://publications.waset.org/abstracts/search?q=Hochschule%20Heilbronn"> Hochschule Heilbronn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We address the question of identifying the configuration space singularities of linkages, i.e., points where the configuration space is not locally a submanifold of Euclidean space.

It is known that Jacobian methods do not provide sufficient conditions for the existence of CS-singularities.

The application of Random Forest, a machine learning method, on a set of adsorption isotherms at a wide range of partial pressures and concentrations is studied. The predicted adsorption isotherms are fitted to several adsorption equations to estimate the adsorption properties. To impute the adsorption properties of desired gases on desired materials, leave-one-out cross-validation is employed.

This waste is as a source of phenolic compounds, such as resveratrol and polydatin, which possess a strong antioxidant capacity. Changes in the amounts of phenols were compared depending on the growing conditions and wine variety. Wastes (grape stems, marc and shoots) from two wineries in the Czech Republic were analyzed. Phenols from these samples were extracted by 40% ethanol. The amount of polyphenols in these extracts was determined by HPLC and their antioxidant capacity by DPPH. We compared changes in the amounts of phenols depending on the type of waste and the wine variety. The most significant source of stilbenoids was waste from pruning (shoots).

The research used partial least squares structural equation modeling (PLS-SEM) and deployed a questionnaire attuned to the awareness and attitudes of business students towards cryptocurrencies and readiness and compatibility of use in universities and colleges in Ilocos Norte. The output of the investigation revealed that awareness of business students is not correlated to the readiness of universities and colleges, which means that even though students understand cryptocurrencies, it is not an assurance that universities and colleges are ready to accept them as the medium of exchange.

Greater and new insights about the general nature of quality are obtained with findings such as in OM, quality has been approached in six fairly distinct paradigms (excellence, value, conformity to specifications, attributes, satisfaction and meeting or exceeding customer expectations), whereas in HCS, two approaches are prominent (Donabedian’s structure, process and outcomes model and Lohr and Schroeder’s circumscribed definition). The two disciplines views on quality seem to have progressed much in parallel with little cross-learning from each other. This work then proposes an encompassing definition of quality as a lever and suggests further research and development avenues for a better use of the concept of quality by academics and practitioners alike toward the goals of greater organizational performance and improved management in healthcare and possibly other service domains. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=healthcare" title="healthcare">healthcare</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=operations" title=" operations"> operations</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a>, <a href="https://publications.waset.org/abstracts/search?q=services" title=" services"> services</a> </p> <a href="https://publications.waset.org/abstracts/74403/towards-better-quality-in-healthcare-and-operations-management-a-developmental-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74403.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">229</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">88</span> Corporate Social Responsibility Practices and Financial Performance: The Case of French Unlisted SMEs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zineb%20Abidi">Zineb Abidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc-Arthur%20Diaye"> Marc-Arthur Diaye</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There exists a large empirical literature concerning the relationship between corporate social responsibility (CSR) and corporate financial performance. This literature, however, applies mainly to large corporations and/or listed firms. To the best of our knowledge, the question of whether meeting CSR requirements impacts the financial performance of small and medium-sized unlisted SMEs has not so far been analyzed. This paper aims to analyze, for the first time, the effect of CSR on the financial performance of SMEs. Using an original database including 5,257 French SMEs, we show that adopting CSR practices has a positive but weak effect on a firm’s financial performance. To develop this further, we analyzed CSR practices interactions assessing the best combination of CSR components that positively influence SME financial performance. Our results show that French SMEs benefit more from their pro-social behavior when they choose a combination of CSR components best adapted to their individual characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate%20social%20responsibility" title="corporate social responsibility">corporate social responsibility</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20performance" title=" financial performance"> financial performance</a>, <a href="https://publications.waset.org/abstracts/search?q=unlisted%20firms" title=" unlisted firms"> unlisted firms</a>, <a href="https://publications.waset.org/abstracts/search?q=SMEs" title=" SMEs"> SMEs</a> </p> <a href="https://publications.waset.org/abstracts/137045/corporate-social-responsibility-practices-and-financial-performance-the-case-of-french-unlisted-smes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137045.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">172</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">87</span> Improving Cyber Resilience in Mobile Field Hospitals: Towards an Assessment Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nasir%20Baba%20Ahmed">Nasir Baba Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Daclin"> Nicolas Daclin</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc%20Olivaux"> Marc Olivaux</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilles%20Dusserre"> Gilles Dusserre</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Mobile field hospital is critical in terms of managing emergencies in crisis. It is a sub-section of the main hospitals and the health sector, tasked with delivering responsive, immediate, and efficient medical services during a crisis. With the aim to prevent further crisis, the assessment of the cyber assets follows different methods, to distinguish its strengths and weaknesses, and in turn achieve cyber resiliency. The work focuses on assessments of cyber resilience in field hospitals with trends growing in both the field hospital and the health sector in general. This creates opportunities for the adverse attackers and the response improvement objectives for attaining cyber resilience, as the assessments allow users and stakeholders to know the level of risks with regards to its cyber assets. Thus, the purpose is to show the possible threat vectors which open up opportunities, with contrast to current trends in the assessment of the mobile field hospitals’ cyber assets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assessment%20framework" title="assessment framework">assessment framework</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber%20resilience" title=" cyber resilience"> cyber resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber%20security" title=" cyber security"> cyber security</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20field%20hospital" title=" mobile field hospital"> mobile field hospital</a> </p> <a href="https://publications.waset.org/abstracts/130214/improving-cyber-resilience-in-mobile-field-hospitals-towards-an-assessment-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130214.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">158</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">86</span> Development of an Efficient Algorithm for Cessna Citation X Speed Optimization in Cruise</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Georges%20Ghazi">Georges Ghazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc-Henry%20Devillers"> Marc-Henry Devillers</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruxandra%20M.%20Botez"> Ruxandra M.

Nowadays, this role has been mainly attributed to the flight management system. This system is an onboard multi-purpose computer responsible for providing the crew members with the optimized flight plan from a destination to the next. To accomplish this function, the flight management system uses a variety of look-up tables to compute the optimal speed and altitude for each flight regime instantly. Because the cruise is the longest segment of a typical flight, the proposed algorithm is focused on minimizing fuel consumption for this flight phase. In this paper, a complete methodology to estimate the aircraft performance and subsequently compute the optimal speed in cruise is presented. Results showed that the obtained performance database was accurate enough to predict the flight costs associated with the cruise phase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cessna%20Citation%20X" title="Cessna Citation X">Cessna Citation X</a>, <a href="https://publications.waset.org/abstracts/search?q=cruise%20speed%20optimization" title=" cruise speed optimization"> cruise speed optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=flight%20cost" title=" flight cost"> flight cost</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20index" title=" cost index"> cost index</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20golden%20section%20search" title=" and golden section search"> and golden section search</a> </p> <a href="https://publications.waset.org/abstracts/85266/development-of-an-efficient-algorithm-for-cessna-citation-x-speed-optimization-in-cruise" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85266.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">292</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">85</span> Trash Dash: An Educational Android Game Application for Proper Waste Segregation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marylene%20S.%20Eder">Marylene S.

The researchers designed the application using Unity 3D and developed the text file that served as the database of the game application. An observation of a pre-school teacher shows that children know how to throw their garbage but they do not know yet how to segregate wastes. After launching the mobile application to K-2 pupils 4 – 5 years of age, the researchers have noticed that children within this age are active and motivated to learn the difference between biodegradable and non-biodegradable. Based on the result of usability test conducted, it was concluded that the game is easy to use and children will most likely use this application frequently. Furthermore, the children may need assistance from their parents and teachers when playing the game. An actual testing of the application has been conducted to different devices as well as functionality test by Thwack Application and it can be concluded that the mobile application can be launched and installed on a device with a minimum API requirement of Gingerbread (2.3.1). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=waste%20segregation" title="waste segregation">waste segregation</a>, <a href="https://publications.waset.org/abstracts/search?q=android%20application" title=" android application"> android application</a>, <a href="https://publications.waset.org/abstracts/search?q=biodegradable" title=" biodegradable"> biodegradable</a>, <a href="https://publications.waset.org/abstracts/search?q=non-biodegradable" title=" non-biodegradable"> non-biodegradable</a> </p> <a href="https://publications.waset.org/abstracts/37949/trash-dash-an-educational-android-game-application-for-proper-waste-segregation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37949.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">445</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">84</span> Sensitivity Studies for a Pin Homojunction a-Si:H Solar Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leila%20Ayat">Leila Ayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Afak%20Meftah"> Afak Meftah </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Amorphous-silicon alloys have great promise as low cost solar cell materials. They have excellent photo-conductivity and high optical absorption to sunlight. Now PIN a-Si:H based solar cells are widely used in power generation modules. However, to improve the performance of these cells further, a better fundamental under-standing of the factors limiting cell performance in the homo junction PIN structure is necessary. In this paper we discuss the sensitivity of light J-V characteristics to various device and material parameters in PIN homo junction solar cells. This work is a numerical simulation of the output parameters of a PIN a-Si:H solar cell under AM1.5 spectrum. These parameters are the short circuit current (Jsc), the open circuit voltage (Voc), the fill factor (FF), the conversion efficiency. The simulation was performed with SCAPS-1D software version 3.3 developed at ELIS in Belgium by Marc Burgelman et al. The obtained results are in agreement with experiment. In addition, the effect of the thickness, doping density, capture cross sections of the gap states and the band microscopic mobilities on the output parameters of the cell are also presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amorphous%20silicon%20p-i-n%20junctions" title="amorphous silicon p-i-n junctions">amorphous silicon p-i-n junctions</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20film" title=" thin film"> thin film</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cells" title=" solar cells"> solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity" title=" sensitivity"> sensitivity</a> </p> <a href="https://publications.waset.org/abstracts/21840/sensitivity-studies-for-a-pin-homojunction-a-sih-solar-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21840.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">521</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">83</span> Equivalent Electrical Model of a Shielded Pulse Planar Transformer in Isolated Gate Drivers for SiC MOSFETs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Loreine%20Makki">Loreine Makki</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc%20Anthony%20Mannah"> Marc Anthony Mannah</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Batard"> Christophe Batard</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Ginot"> Nicolas Ginot</a>, <a href="https://publications.waset.org/abstracts/search?q=Julien%20Weckbrodt"> Julien Weckbrodt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Planar transformers are extensively utilized in high-frequency, high power density power electronic converters.

Unfortunately, user comfort was not always a priority design criterion throughout their development. To further improve this technology, exoskeletons should operate and deliver assistance without causing discomfort to the user. For this, improvements are necessary from an ergonomic point of view. The device’s control method is important when endeavoring to enhance user comfort. Exoskeleton or rehabilitation device controllers use methods of control called interaction controls (admittance and impedance controls). This paper proposes an extended version of an admittance controller to enhance user comfort. The control method used consists of adding an inner loop that is controlled by a proportional-integral-derivative (PID) controller. This allows the interaction force to be kept as close as possible to the desired force trajectory. The force-tracking admittance controller modifies the actuation force of the system in order to follow both the desired motion trajectory and the desired relative force between the user and the exoskeleton. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobility%20assistive%20device" title="mobility assistive device">mobility assistive device</a>, <a href="https://publications.waset.org/abstracts/search?q=exoskeleton" title=" exoskeleton"> exoskeleton</a>, <a href="https://publications.waset.org/abstracts/search?q=force-tracking%20admittance%20controller" title=" force-tracking admittance controller"> force-tracking admittance controller</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20comfort" title=" user comfort"> user comfort</a> </p> <a href="https://publications.waset.org/abstracts/133918/enhancing-human-mobility-exoskeleton-comfort-using-admittance-controller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133918.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">156</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">81</span> Homing of B Cells via Afferent Lymphatics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Pereira-Nogueira">Sara Pereira-Nogueira</a>, <a href="https://publications.waset.org/abstracts/search?q=Tim%20Worbs"> Tim Worbs</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc%20Permanyer-Bosser"> Marc Permanyer-Bosser</a>, <a href="https://publications.waset.org/abstracts/search?q=Reinhold%20F%C3%B6rster"> Reinhold Förster</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While the entry mechanism of lymphocytes into the lymph node via the blood are well described, it is still largely unknown how cells enter lymph nodes that arrive via afferent lymphatics. In order to address this, our group has established a micro-injection technique in mice through which cells are delivered directly into the lymphatic vessel immediately afferent to the popliteal lymph node. Injected cells can then be tracked via multi-colour fluorescence or 2-photon microscopy, and their localization can be analysed within the popliteal or downstream lymph nodes by immunohistology. Since naïve B cells express the chemokine receptor CXCR5 we intra-lymphatically co-injected B cells derived from wildtype and Cxcr5-deficient mice. While CXCR5 does not play a role in guiding B cells out of the subcapsular sinus, it affects their positioning within the lymph node parenchyma, since CXCR5-deficient B cells are impaired in migrating into the B cell follicle. The knowledge obtained by studying B-cell migration may prove beneficial in clinical settings regarding tumor metastasis or autoimmune diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=afferent%20lymphatics" title="afferent lymphatics">afferent lymphatics</a>, <a href="https://publications.waset.org/abstracts/search?q=B%20cell%20migration" title=" B cell migration"> B cell migration</a>, <a href="https://publications.waset.org/abstracts/search?q=chemokine" title=" chemokine"> chemokine</a>, <a href="https://publications.waset.org/abstracts/search?q=intra-lymphatic%20injection" title=" intra-lymphatic injection"> intra-lymphatic injection</a> </p> <a href="https://publications.waset.org/abstracts/75819/homing-of-b-cells-via-afferent-lymphatics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75819.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">263</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">80</span> Anthropomorphic Interfaces For User Trust in a Highly Automated Driving</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Clarisse%20Lawson-Guidigbe">Clarisse Lawson-Guidigbe</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Louveton"> Nicolas Louveton</a>, <a href="https://publications.waset.org/abstracts/search?q=Kahina%20Amokrane-Ferka"> Kahina Amokrane-Ferka</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Marc%20Andre"> Jean-Marc Andre</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Trust in automated driving systems is receiving growing attention in the research community. Anthropomorphism has been identified by past research as a trust-building factor. In this paper, we consider three anthropomorphic interfaces integrating three versions of a virtual assistant. We attempt to measure the impact of each of these interfaces on trust in the automated driving system. An experiment following a between-subject design was conducted in a driving simulator (N = 36) to evaluate participants’ performance and experience in two handover situations (a simple one and a critical one). Perception of anthropomorphism and trust was measured using scales, while participants’ experience was measured during elicitation interviews. We found no significant difference between the three interfaces regarding the perception of anthropomorphism, trust levels, or experience. However, regarding participants’ performance, we found a significant difference between the three interfaces in the simple handover situations but not the critical one. Learnings from anthropomorphism and trust measurement scales are discussed and suggestions for further research are proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=highly%20automated%20driving" title="highly automated driving">highly automated driving</a>, <a href="https://publications.waset.org/abstracts/search?q=trust" title=" trust"> trust</a>, <a href="https://publications.waset.org/abstracts/search?q=anthropomorphic%20design" title=" anthropomorphic design"> anthropomorphic design</a>, <a href="https://publications.waset.org/abstracts/search?q=mindful%20anthropomorphism" title=" mindful anthropomorphism"> mindful anthropomorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=mindless%20anthropomorphism" title=" mindless anthropomorphism"> mindless anthropomorphism</a> </p> <a href="https://publications.waset.org/abstracts/146868/anthropomorphic-interfaces-for-user-trust-in-a-highly-automated-driving" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146868.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">147</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">79</span> Optimized Simultaneous Determination of Theobromine and Caffeine in Fermented and Unfermented Cacao Beans and in Cocoa Products Using Step Gradient Solvent System in Reverse Phase HPLC</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ian%20Marc%20G.%20Cabugsa">Ian Marc G.

The samples tested were raw, fermented, and roasted cacao beans as well as commercially available cocoa products. The HPLC analysis was carried out using step gradient solvent system with acetonitrile and water buffered with H3PO4 as the mobile phase. The HPLC system was optimized using 273 nm wavelength at 35 °C for the column temperature with a flow rate of 1.0 mL/min. Using this method, the theobromine percent recovery mean, Limit of Detection (LOD) and Limit of Quantification (LOQ) is 118.68(±3.38)%, 0.727 and 1.05 respectively. The percent recovery mean, LOD and LOQ for caffeine is 105.53(±3.25)%, 2.42 and 3.50 respectively. The inter-day and intra-day precision for theobromine is 4.31% and 4.48% respectively, while 7.02% and 7.03% was for caffeine respectively. Compared to the standard method in AOAC using methanol in isocratic solvent system, the results of the study produced lesser chromatogram noise with emphasis on theobromine and caffeine. The method is readily usable for cacao and cocoa substances analyses using HPLC with step gradient capability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cacao" title="cacao">cacao</a>, <a href="https://publications.waset.org/abstracts/search?q=caffeine" title=" caffeine"> caffeine</a>, <a href="https://publications.waset.org/abstracts/search?q=HPLC" title=" HPLC"> HPLC</a>, <a href="https://publications.waset.org/abstracts/search?q=step%20gradient%20solvent%20system" title=" step gradient solvent system"> step gradient solvent system</a>, <a href="https://publications.waset.org/abstracts/search?q=theobromine" title=" theobromine"> theobromine</a> </p> <a href="https://publications.waset.org/abstracts/43155/optimized-simultaneous-determination-of-theobromine-and-caffeine-in-fermented-and-unfermented-cacao-beans-and-in-cocoa-products-using-step-gradient-solvent-system-in-reverse-phase-hplc" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43155.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">281</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">78</span> Development of Tools for Multi Vehicles Simulation with Robot Operating System and ArduPilot</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pierre%20Kancir">Pierre Kancir</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Philippe%20Diguet"> Jean-Philippe Diguet</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc%20Sevaux"> Marc Sevaux</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the main difficulties in developing multi-robot systems (MRS) is related to the simulation and testing tools available. Indeed, if the differences between simulations and real robots are too significant, the transition from the simulation to the robot won’t be possible without another long development phase and won’t permit to validate the simulation. Moreover, the testing of different algorithmic solutions or modifications of robots requires a strong knowledge of current tools and a significant development time. Therefore, the availability of tools for MRS, mainly with flying drones, is crucial to enable the industrial emergence of these systems. This research aims to present the most commonly used tools for MRS simulations and their main shortcomings and presents complementary tools to improve the productivity of designers in the development of multi-vehicle solutions focused on a fast learning curve and rapid transition from simulations to real usage. The proposed contributions are based on existing open source tools as Gazebo simulator combined with ROS (Robot Operating System) and the open-source multi-platform autopilot ArduPilot to bring them to a broad audience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ROS" title="ROS">ROS</a>, <a href="https://publications.waset.org/abstracts/search?q=ArduPilot" title=" ArduPilot"> ArduPilot</a>, <a href="https://publications.waset.org/abstracts/search?q=MRS" title=" MRS"> MRS</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=drones" title=" drones"> drones</a>, <a href="https://publications.waset.org/abstracts/search?q=Gazebo" title=" Gazebo"> Gazebo</a> </p> <a href="https://publications.waset.org/abstracts/100338/development-of-tools-for-multi-vehicles-simulation-with-robot-operating-system-and-ardupilot" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100338.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">210</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">77</span> Portfolio Selection with Active Risk Monitoring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marc%20S.%20Paolella">Marc S.

It introduces a so-called risk fear portfolio strategy which combines portfolio optimization with active risk monitoring. The former selects optimal portfolio weights. The latter, independently, initiates market exit in case of excessive risks. The strategy agrees with the stylized fact of stock market major sell-offs during the initial stage of market downturns. The advantages of the new framework are illustrated with an extensive empirical study. It leads to superior multivariate density and Value-at-Risk forecasting, and better portfolio performance. The proposed risk fear portfolio strategy outperforms various competing types of optimal portfolios, even in the presence of conservative transaction costs and frequent rebalancing. The risk monitoring of the optimal portfolio can serve as an early warning system against large market risks. In particular, the new strategy avoids all the losses during the 2008 financial crisis, and it profits from the subsequent market recovery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comfort" title="comfort">comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20crises" title=" financial crises"> financial crises</a>, <a href="https://publications.waset.org/abstracts/search?q=portfolio%20optimization" title=" portfolio optimization"> portfolio optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20monitoring" title=" risk monitoring"> risk monitoring</a> </p> <a href="https://publications.waset.org/abstracts/28504/portfolio-selection-with-active-risk-monitoring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28504.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">524</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">76</span> A Comparative Analysis on the Perspectives of Secular and Non-Secular Male Groups on Female Masturbation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marc%20Angelo%20C.%20Balon">Marc Angelo C.

In fact, it is not widely talked about specifically in the Philippines since the Filipino culture still preserves the space for conservativeness. Although, considering the numerous and emerging studies on female masturbation, this study will focus on the perspectives of secular and non-secular male groups with regard to female masturbation. The objectives of this study is to identify the perceptions of these male groups and their taking on considering women who masturbate as their sexual partner, as a sexual object, and as a life partner and lastly, to have a comparative analysis of the perceptions of these male groups drawing out their sense of meaning on the masturbation of women. The researchers made use of purposive sampling technique and interview guide questionnaire. The secular male group were psychology students while the non-secular male group was drawn from a Catholic Church seminary in Tagaytay City, Cavite. Results showed that the secular male group had scientific perspectives such as exploring the genitals, contradicting moral perspectives on masturbation as a regular practice, while the non-secular male groups had theological perspectives in accordance with the fundamental moral theology, moral perspectives and perspectives on masturbation as a regular practice. Moreover, men who came from the non-secular group highly believe that masturbation is immoral. Otherwise, men who came from the secular group noted that masturbation is primary physiological need. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=secular" title="secular">secular</a>, <a href="https://publications.waset.org/abstracts/search?q=non-secular" title=" non-secular"> non-secular</a>, <a href="https://publications.waset.org/abstracts/search?q=masturbation" title=" masturbation"> masturbation</a>, <a href="https://publications.waset.org/abstracts/search?q=comparative%20analysis" title=" comparative analysis"> comparative analysis</a> </p> <a href="https://publications.waset.org/abstracts/61292/a-comparative-analysis-on-the-perspectives-of-secular-and-non-secular-male-groups-on-female-masturbation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61292.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">274</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">75</span> Optimization of Cacao Fermentation in Davao Philippines Using Sustainable Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ian%20Marc%20G.%20Cabugsa">Ian Marc G.

Cacao samples with weights ranging from 150-250 kilograms were collected from various cacao farms in Davao City and Zamboanga City Philippines. Different fermentation techniques were used starting with design of the sweat box, prefermentation conditionings, number of days for fermentation and number of turns. As the beans are being fermented, its temperature was regularly monitored using a digital thermometer. The resultant cacao beans were assessed using physical and chemical means. For the physical assessment, the bean cut test, bean count tests, and sensory test were used. Quantification of theobromine, caffeine, and antioxidants in the form of equivalent quercetin was used for chemical assessment. Both the theobromine and caffeine were analyzed using HPLC method while the antioxidant was analyzed spectrometrically. To come up with the best fermentation procedure, the different assessment were given priority coefficients wherein the physical tests – taste test, cut, and bean count tests were given priority over the results of the chemical test. The result of the study was an optimized fermentation protocol that is readily adaptable and transferable to any cacao cooperatives or groups in Mindanao or even Philippines as a whole. <p
