Assay is a fully automated assay on the Panther system. It is based on Transcription-Mediated Amplification and real time detection technologies. This assay is intended for monitoring HIV-1 viral load in plasma specimens and for the detection of HIV-1 in plasma and serum specimens. Nine-hundred and seventy nine specimens selected at random from routine testing at St Thomas’ Hospital, London were anonymised and used to compare the performance of the Aptima HIV-1 Quant Dx assay and Roche COBAS® AmpliPrep/COBAS® TaqMan® HIV-1 Test, v2.0. Two-hundred and thirty four specimens gave quantitative HIV-1 viral load results in both assays. The quantitative results reported by the Aptima Assay were comparable those reported by the Roche COBAS AmpliPrep/COBAS TaqMan HIV-1 Test, v2.0 with a linear regression slope of 1.04 and an intercept on -0.097. The Aptima assay detected HIV-1 in more samples than the Roche assay. This was not due to lack of specificity of the Aptima assay because this assay gave 99.83% specificity on testing plasma specimens from 600 HIV-1 negative individuals. To understand the reason for this higher detection rate a side-by-side comparison of low level panels made from the HIV-1 3rd international standard (NIBSC10/152) and clinical samples of various subtypes were tested in both assays. The Aptima assay was more sensitive than the Roche assay. The good sensitivity, specificity and agreement with other commercial assays make the HIV-1 Quant Dx Assay appropriate for both viral load monitoring and detection of HIV-1 infections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HIV%20viral%20load" title="HIV viral load">HIV viral load</a>, <a href="https://publications.waset.org/abstracts/search?q=Aptima" title=" Aptima"> Aptima</a>, <a href="https://publications.waset.org/abstracts/search?q=Roche" title=" Roche"> Roche</a>, <a href="https://publications.waset.org/abstracts/search?q=Panther%20system" title=" Panther system"> Panther system</a> </p> <a href="https://publications.waset.org/abstracts/21163/performance-of-the-aptima-hiv-1-quant-dx-assay-on-the-panther-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21163.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">375</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">99</span> Comparison of Different DNA Extraction Platforms with FFPE tissue</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wang%20Yanping%20Karen">Wang Yanping Karen</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Rafeah%20Siti"> Mohd Rafeah Siti</a>, <a href="https://publications.waset.org/abstracts/search?q=Park%20MI%20Kyoung"> Park MI Kyoung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Formalin-fixed paraffin embedded (FFPE) tissue is important in the area of oncological diagnostics. This method of preserving tissues enabling them to be stored easily at ambient temperature for a long time. This decreases the risk of losing the DNA quantity and quality after extraction, reducing sample wastage, and making FFPE more cost effective. However, extracting DNA from FFPE tissue is a challenge as DNA purified is often highly cross-linked, fragmented, and degraded. In addition, this causes problems for many downstream processes. In this study, there will be a comparison of DNA extraction efficiency between One BioMed’s Xceler8 automated platform with commercial available extraction kits (Qiagen and Roche). The FFPE tissue slices were subjected to deparaffinization process, pretreatment and then DNA extraction using the three mentioned platforms. The DNA quantity were determined with real-time PCR (BioRad CFX ) and gel electrophoresis. The amount of DNA extracted with the One BioMed’s X8 platform was found to be comparable with the other two manual extraction kits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA%20extraction" title="DNA extraction">DNA extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=FFPE%20tissue" title=" FFPE tissue"> FFPE tissue</a>, <a href="https://publications.waset.org/abstracts/search?q=qiagen" title=" qiagen"> qiagen</a>, <a href="https://publications.waset.org/abstracts/search?q=roche" title=" roche"> roche</a>, <a href="https://publications.waset.org/abstracts/search?q=one%20biomed%20X8" title=" one biomed X8"> one biomed X8</a> </p> <a href="https://publications.waset.org/abstracts/153540/comparison-of-different-dna-extraction-platforms-with-ffpe-tissue" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153540.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">107</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> Leisure, Domestic or Professional Activities so as to Prevent Cognitive Decline: Results FreLE Longitudinal Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Caroline%20Dupre">Caroline Dupre</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Hupin"> David Hupin</a>, <a href="https://publications.waset.org/abstracts/search?q=Christ%20Goumou"> Christ Goumou</a>, <a href="https://publications.waset.org/abstracts/search?q=Francois%20Belan"> Francois Belan</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Roche"> Frederic Roche</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Celarier"> Thomas Celarier</a>, <a href="https://publications.waset.org/abstracts/search?q=Bienvenu%20Bongue"> Bienvenu Bongue</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Previous cohorts have been notably criticized for not studying the different type of physical activity and not investigating household activities. The objective of this work was to analyse the relationship between physical activity and cognitive decline in older people living in the community. Impact of type of physical activity on the results has been realised. Methods: The study used data from the longitudinal and observational study , FrèLE (FRagility: Longitudinal Study of Expressions). The collected data included: socio-demographic variables, lifestyle, and health status (frailty, comorbidities, cognitive status, depression). Cognitive decline was assessed by using: Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). Physical activity was assessed by the Physical Activity Scale for the Elderly (PASE). This tool is structured in three sections: the leisure activity, domestic activity, and professional activity. Logistic regressions and proportional hazards regression models (Cox) were used to estimate the risk of cognitive disorders. Results: At baseline, the prevalence of cognitive disorders was 6.9% according to MMSE. In total, 1167 participants without cognitive disorders were included in the analysis. The mean age was 77.4 years, and 52.1% of the participants were women. After a 2 years long follow-up, we found cognitive disorders on 53 participants (4.5%). Physical activity at baseline is lower in older adults for whom cognitive decline was observed after two years of follow-up. Subclass analyses showed that leisure and domestic activities were associated with cognitive decline, but not professional activities. Conclusions: Analysis showed a relationship between cognitive disorders and type of physical activity. The current study will be completed by the MoCA for mild cognitive impairment. These findings compared to other ongoing studies, will contribute to the debate on the beneficial effects of physical activity on cognition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aging" title="aging">aging</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20function" title=" cognitive function"> cognitive function</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20activity" title=" physical activity"> physical activity</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20models" title=" mixed models"> mixed models</a> </p> <a href="https://publications.waset.org/abstracts/110278/leisure-domestic-or-professional-activities-so-as-to-prevent-cognitive-decline-results-frele-longitudinal-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110278.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">126</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">97</span> An Original and Suitable Induction Method of Repeated Hypoxic Stress by Hydralazine to Investigate the Integrity of an in Vitro Contact Co-Culture Blood Brain Barrier Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Morgane%20Chatard">Morgane Chatard</a>, <a href="https://publications.waset.org/abstracts/search?q=Cl%C3%A9mentine%20Puech"> Clémentine Puech</a>, <a href="https://publications.waset.org/abstracts/search?q=Nathalie%20Perek"> Nathalie Perek</a>, <a href="https://publications.waset.org/abstracts/search?q=Fr%C3%A9d%C3%A9ric%20Roche"> Frédéric Roche</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Several neurological disorders are linked to repeated hypoxia. The impact of such repeated hypoxic stress, on endothelial cells function of the blood-brain barrier (BBB) is little studied in the literature. Indeed, the study of hypoxic stress in cellular pathways is complex using hypoxia exposure because HIF 1α (factor induced by hypoxia) has a short half life. Our study presents an innovative induction method of repeated hypoxic stress, more reproducible, which allows us to study its impacts on an in vitro contact co-culture BBB model. Repeated hypoxic stress was induced by hydralazine (a mimetic agent of hypoxia pathway) during two hours and repeated during 24 hours. Then, BBB integrity was assessed by permeability measurements (transendothelial electrical resistance and membrane permeability), tight junction protein expressions (cell-ELISA and confocal microscopy) and by studying expression and activity of efflux transporters. First, this study showed that repeated hypoxic stress leads to a BBB’s dysfunction illustrated by a significant increase in permeability. This loss of membrane integrity was linked to a significant decrease of tight junctions’ protein expressions, facilitating a possible transfer of potential cytotoxic compounds in the brain. Secondly, we demonstrated that brain microvascular endothelial cells had set-up defence mechanism. These endothelial cells significantly increased the activity of their efflux transporters which was associated with a significant increase in their expression. In conclusion, repeated hypoxic stress lead to a loss of BBB integrity with a decrease of tight junction proteins. In contrast, endothelial cells increased the expression of their efflux transporters to fight against cytotoxic compounds brain crossing. Unfortunately, enhanced efflux activity could also lead to reducing pharmacological drugs delivering to the brain in such hypoxic conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BBB%20model" title="BBB model">BBB model</a>, <a href="https://publications.waset.org/abstracts/search?q=efflux%20transporters" title=" efflux transporters"> efflux transporters</a>, <a href="https://publications.waset.org/abstracts/search?q=repeated%20hypoxic%20stress" title=" repeated hypoxic stress"> repeated hypoxic stress</a>, <a href="https://publications.waset.org/abstracts/search?q=tigh%20junction%20proteins" title=" tigh junction proteins"> tigh junction proteins</a> </p> <a href="https://publications.waset.org/abstracts/50235/an-original-and-suitable-induction-method-of-repeated-hypoxic-stress-by-hydralazine-to-investigate-the-integrity-of-an-in-vitro-contact-co-culture-blood-brain-barrier-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50235.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">96</span> Cut-Off of CMV Cobas® Taqman® (CAP/CTM Roche®) for Introduction of Ganciclovir Pre-Emptive Therapy in Allogeneic Hematopoietic Stem Cell Transplant Recipients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20B.%20S.%20Pereira">B.

M. Machado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The introduction of prophylactic or preemptive therapies has effectively decreased the CMV mortality rates after hematopoietic stem cell transplantation (HSCT). CMV antigenemia (pp65) or quantitative PCR are methods currently approved for CMV surveillance in pre-emptive strategies. Commercial assays are preferred as cut-off levels defined by in-house assays may vary among different protocols and in general show low reproducibility. Moreover, comparison of published data among different centers is only possible if international standards of quantification are included in the assays. Recently, the World Health Organization (WHO) established the first international standard for CMV detection. The real time PCR COBAS Ampliprep/ CobasTaqMan (CAP/CTM) (Roche®) was developed using the WHO standard for CMV quantification. However, the cut-off for the introduction of antiviral has not been determined yet. Methods: We conducted a retrospective study to determine: 1) the sensitivity and specificity of the new CMV CAP/CTM test in comparison with pp65 antigenemia to detect episodes of CMV infection/reactivation, and 2) the cut-off of viral load for introduction of ganciclovir (GCV). Pp65 antigenemia was performed and the corresponding plasma samples were stored at -20°C for further CMV detection by CAP/CTM. Comparison of tests was performed by kappa index. The appearance of positive antigenemia was considered the state variable to determine the cut-off of CMV viral load by ROC curve. Statistical analysis was performed using SPSS software version 19 (SPSS, Chicago, IL, USA.). Results: Thirty-eight patients were included and followed from August 2014 through May 2015. The antigenemia test detected 53 episodes of CMV infection in 34 patients (89.5%), while CAP/CTM detected 37 episodes in 33 patients (86.8%). AG and PCR results were compared in 431 samples and Kappa index was 30.9%. The median time for first AG detection was 42 (28-140) days, while CAP/CTM detected at a median of 7 days earlier (34 days, ranging from 7 to 110 days). The optimum cut-off value of CMV DNA was 34.25 IU/mL to detect positive antigenemia with 88.2% of sensibility, 100% of specificity and AUC of 0.91. This cut-off value is below the limit of detection and quantification of the equipment which is 56 IU/mL. According to CMV recurrence definition, 16 episodes of CMV recurrence were detected by antigenemia (47.1%) and 4 (12.1%) by CAP/CTM. The duration of viremia as detected by antigenemia was shorter (60.5% of the episodes lasted ≤ 7 days) in comparison to CAP/CTM (57.9% of the episodes lasting 15 days or more). This data suggests that the use of antigenemia to define the duration of GCV therapy might prompt early interruption of antiviral, which may favor CMV reactivation. The CAP/CTM PCR could possibly provide a safer information concerning the duration of GCV therapy. As prolonged treatment may increase the risk of toxicity, this hypothesis should be confirmed in prospective trials. Conclusions: Even though CAP/CTM by ROCHE showed great qualitative correlation with the antigenemia technique, the fully automated CAP/CTM did not demonstrate increased sensitivity. The cut-off value below the limit of detection and quantification may result in delayed introduction of pre-emptive therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antigenemia" title="antigenemia">antigenemia</a>, <a href="https://publications.waset.org/abstracts/search?q=CMV%20COBAS%2FTAQMAN" title=" CMV COBAS/TAQMAN"> CMV COBAS/TAQMAN</a>, <a href="https://publications.waset.org/abstracts/search?q=cytomegalovirus" title=" cytomegalovirus"> cytomegalovirus</a>, <a href="https://publications.waset.org/abstracts/search?q=antiviral%20cut-off" title=" antiviral cut-off"> antiviral cut-off</a> </p> <a href="https://publications.waset.org/abstracts/56757/cut-off-of-cmv-cobas-taqman-capctm-roche-for-introduction-of-ganciclovir-pre-emptive-therapy-in-allogeneic-hematopoietic-stem-cell-transplant-recipients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56757.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">191</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">95</span> Establishment and Aging Process Analysis in Dermal Fibroblast Cell Culture of Green Turtle (Chelonia mydas)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yemima%20Dani%20Riani">Yemima Dani Riani</a>, <a href="https://publications.waset.org/abstracts/search?q=Anggraini%20Barlian"> Anggraini Barlian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Green turtle (Chelonia mydas) is one of well known long-lived turtle. Its age can reach 100 years old. Senescence in green turtle is an interesting process to study because until now no clear explanation has been established about senescence at cellular or molecular level in this species. Since 1999, green turtle announced as an endangered species. Hence, establishment of fibroblast skin cell culture of green turtle may be material for future study of senescence. One common marker used for detecting senescence is telomere shortening. Reduced telomerase activity, the reverse transcriptase enzyme which adds TTAGGG DNA sequence to telomere end, may also cause senescence. The purpose of this research are establish and identify green turtle fibroblast skin cell culture and also compare telomere length and telomerase activity from passage 5 and 14. Primary cell culture made with primary explant method then cultured in Leibovitz-15 (Sigma) supplemented by 10% Fetal Bovine Serum (Sigma) and 100 U/mL Penicillin/Streptomycin (Sigma) at 30 ± 1oC. Cells identified with Rabbit Anti-Vimentin Polyclonal Antibody (Abcam) and Goat Polyclonal Antibody (Abcam) using confocal microscope (Zeiss LSM 170). Telomere length obtained using TeloTAGGG Telomere Length Assay (Roche) while telomerase activity obtained using TeloTAGGG Telomerase PCR ElisaPlus (Roche). Primary cell culture from green turtle skin had fibroblastic morphology and immunocytochemistry test with vimentin antibody proved the culture was fibroblast cell. Measurement of telomere length and telomerase activity showed that telomere length and telomerase activity of passage 14 was greater than passage 5. However, based on morphology, green turtle fibroblast skin cell culture showed senescent morphology. Based on the analysis of telomere length and telomerase activity, suspected fibroblast skin cell culture of green turtles is not undergo aging through telomere shortening. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell%20culture" title="cell culture">cell culture</a>, <a href="https://publications.waset.org/abstracts/search?q=chelonia%20mydas" title=" chelonia mydas"> chelonia mydas</a>, <a href="https://publications.waset.org/abstracts/search?q=telomerase" title=" telomerase"> telomerase</a>, <a href="https://publications.waset.org/abstracts/search?q=telomere" title=" telomere"> telomere</a>, <a href="https://publications.waset.org/abstracts/search?q=senescence" title=" senescence"> senescence</a> </p> <a href="https://publications.waset.org/abstracts/15170/establishment-and-aging-process-analysis-in-dermal-fibroblast-cell-culture-of-green-turtle-chelonia-mydas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15170.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">425</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">94</span> Thyroid Dysfunction in Patients with Chronic Hemodialysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benghezel%20Hichem">Benghezel Hichem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thyroid dysfunction in hemodialysis subjects is represented mainly by hypothyroidism. The objective of our work is to determine the thyroid profile of our hemodialysis patients and to highlight the prevalence of different thyroid disorders. Methods: This is a retrospective study performed on a mono centric 2 months (February and March 2013) on 42 hemodialysis patients (11 male and 31 female). We made the dosage of thyroid hormones Thyrotropin (TSH) ((free thyroxin ) FT4 and free Triodothyronin ) FT3) by chemiluminescence immunoassay method on cobas 6000 Roche Diagnostics. The results: The prevalence of biological hypothyroidism was 18% (7% with a high TSH isolated and a mean +/- SD 9.44 +/- 6.29, 5% with high TSH, and with low FT4 a mean +/- SD is 8.18 +/- 0.53 for TSH and 9.69 +/- 0.22 for FT4, One patient with a high TSH, and low FT4, FT3. 4% of patients with a low T3 syndrome with a mean +/- SD of 3.93 +/- 0,3 for FT3), we notice that 5% of patients with hyperthyroidism TSH collapsed and mean +/- SD of TSH is 0.017 +/- 0,001.

Hence, it needs to rethink tools, technologies and platforms in order to efficiently achieve its goals. A few tools have emerged since 2010 such as CommunityViz, GeoPlanner, etc. In the era of Web 2.0 and collaboration, WikiGIS has been proposed as a new category of tools. In this paper, we present WikiGIS functionalities dealing mainly with the iteration and traceability management to support the collaboration of the Geodesign process. Actually, WikiGIS is built on GeoWeb 2.0 technologies —and primarily on wiki— and aims at managing the tracking of participants’ editing. This paper focuses on a simplified simulation to illustrate the strength of WikiGIS in the management of traceability and in the access to history in a Geodesign process. Indeed, a cartographic user interface has been implemented, and then a hypothetical use case has been imagined as proof of concept. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geodesign" title="geodesign">geodesign</a>, <a href="https://publications.waset.org/abstracts/search?q=history" title=" history"> history</a>, <a href="https://publications.waset.org/abstracts/search?q=traceability" title=" traceability"> traceability</a>, <a href="https://publications.waset.org/abstracts/search?q=tracking%20of%20participants%E2%80%99%20editing" title=" tracking of participants’ editing"> tracking of participants’ editing</a>, <a href="https://publications.waset.org/abstracts/search?q=WikiGIS" title=" WikiGIS"> WikiGIS</a> </p> <a href="https://publications.waset.org/abstracts/54647/a-simulated-scenario-of-wikigis-to-support-the-iteration-and-traceability-management-of-the-geodesign-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54647.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">247</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">92</span> Comparison of Nucleic Acid Extraction Platforms On Tissue Samples</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siti%20Rafeah%20Md%20Rafei">Siti Rafeah Md Rafei</a>, <a href="https://publications.waset.org/abstracts/search?q=Karen%20Wang%20Yanping"> Karen Wang Yanping</a>, <a href="https://publications.waset.org/abstracts/search?q=Park%20Mi%20Kyoung"> Park Mi Kyoung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tissue samples are precious supply for molecular studies or disease identification diagnosed using molecular assays, namely real-time PCR (qPCR).

This study examines particular elements within Chopin's piano works and how they can be interpreted and instructed to those who are not acquainted with his pieces. The theory suggests that particular melodic attributes can be found in Chopin's piano compositions. Therefore, various elements can be recognized, such as polyphonic textures, decorated phrases, themes and variations, inner patterns tuning, blending harmonics, and conflicting beats. These characteristics were discovered within theoretical analysis has identified many of Chopin's compositions.

After a brief reminder of the Dark Gravity theory foundations, the confrontation with the main cosmological probes is carried out. We show that, amazingly, the sudden transition between the usual matter dominated decelerated expansion law a(t) ∝ t²/³ and this accelerated expansion law a(t) ∝ t² predicted by the theory should be able to fit the main cosmological probes (SN, BAO, CMB and age of the oldest stars data) but also direct H₀ measurements with two free parameters only: H₀ and the transition redshift. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-gravity" title="anti-gravity">anti-gravity</a>, <a href="https://publications.waset.org/abstracts/search?q=negative%20energies" title=" negative energies"> negative energies</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20reversal" title=" time reversal"> time reversal</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20discontinuities" title=" field discontinuities"> field discontinuities</a>, <a href="https://publications.waset.org/abstracts/search?q=dark%20energy%20theory" title=" dark energy theory"> dark energy theory</a> </p> <a href="https://publications.waset.org/abstracts/185998/dark-gravity-confronted-with-supernovae-baryonic-oscillations-and-cosmic-microwave-background-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185998.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">56</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> Introduction of the Fluid-Structure Coupling into the Force Analysis Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oc%C3%A9ane%20Grosset">Océane Grosset</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20P%C3%A9zerat"> Charles Pézerat</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Hugh%20Thomas"> Jean-Hugh Thomas</a>, <a href="https://publications.waset.org/abstracts/search?q=Fr%C3%A9d%C3%A9ric%20Ablitzer"> Frédéric Ablitzer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a method to take into account the fluid-structure coupling into an inverse method, the Force Analysis Technique (FAT). The FAT method, also called RIFF method (Filtered Windowed Inverse Resolution), allows to identify the force distribution from local vibration field. In order to only identify the external force applied on a structure, it is necessary to quantify the fluid-structure coupling, especially in naval application, where the fluid is heavy. This method can be decomposed in two parts, the first one consists in identifying the fluid-structure coupling and the second one to introduced it in the FAT method to reconstruct the external force.

Methods: A total of 40 E. coli from stool samples were tested. Six were previously characterized as resistant to carbapenems and documented by PCR. The remaining 34 isolates previously tested susceptible to carbapenems and were negative for these genes. Bacterial RNA was extracted using manual method. The real-time PCR was performed using the Light Cycler III 480 instrument (Roche) and specific primers for each carbapenemase target were used. Results: Each one of the two carbapenemase gene tested presented a different melting curve after PCR amplification. The melting temperature (Tm) analysis of the amplicons identified was as follows: blaIMP type (Tm 82.18°C), blaNDM-1 (Tm 78.8°C). No amplification was detected among the negative samples. The results showed 100% concordance with the genotypes previously identified. Conclusions: The new assay was able to detect the presence of two different carbapenemase gene type by real-time PCR. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=resistance" title="resistance">resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=b-lactamases" title=" b-lactamases"> b-lactamases</a>, <a href="https://publications.waset.org/abstracts/search?q=E.%20coli" title=" E. coli"> E. coli</a>, <a href="https://publications.waset.org/abstracts/search?q=real-time%20PCR" title=" real-time PCR"> real-time PCR</a> </p> <a href="https://publications.waset.org/abstracts/9399/rapid-detection-of-mbl-genes-by-sybr-green-based-real-time-pcr" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9399.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">411</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> Scattering Operator and Spectral Clustering for Ultrasound Images: Application on Deep Venous Thrombi</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thibaud%20Berthomier">Thibaud Berthomier</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Mansour"> Ali Mansour</a>, <a href="https://publications.waset.org/abstracts/search?q=Luc%20Bressollette"> Luc Bressollette</a>, <a href="https://publications.waset.org/abstracts/search?q=Fr%C3%A9d%C3%A9ric%20Le%20Roy"> Frédéric Le Roy</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominique%20Mottier"> Dominique Mottier</a>, <a href="https://publications.waset.org/abstracts/search?q=L%C3%A9o%20Fr%C3%A9chier"> Léo Fréchier</a>, <a href="https://publications.waset.org/abstracts/search?q=Barth%C3%A9l%C3%A9my%20Hermenault"> Barthélémy Hermenault</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Deep Venous Thrombosis (DVT) occurs when a thrombus is formed within a deep vein (most often in the legs).

Data such as videos and audio files are becoming increasingly large. As a result, transporting them over the Internet is becoming difficult. Therefore, it has been important to establish a method to locally interconnect autonomous systems (AS) with each other to facilitate traffic exchange. It is in this context that Internet Exchange Points (IXPs) are set up to facilitate local and even regional traffic. They are now the lifeblood of the Internet. Therefore, it is important to think about the factors that can characterize IXPs. However, other more quantifiable characteristics can help determine the quality of an IXP. In addition, these characteristics may allow ISPs to have a clearer view of the exchange node and may also convince other networks to connect to an IXP. To that end, we define five new IXP characteristics: the attraction rate (τₐₜₜᵣ); and the peering rate (τₚₑₑᵣ); the target rate of an IXP (Objₐₜₜ); the number of IXP links (Nₗᵢₙₖ); the resistance rate τₑ𝒻𝒻 and the attraction failure rate (τ𝒻). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=characteristic" title="characteristic">characteristic</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomous%20system" title=" autonomous system"> autonomous system</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20service%20provider" title=" internet service provider"> internet service provider</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20exchange%20point" title=" internet exchange point"> internet exchange point</a>, <a href="https://publications.waset.org/abstracts/search?q=rate" title=" rate"> rate</a> </p> <a href="https://publications.waset.org/abstracts/154515/characterization-of-internet-exchange-points-by-using-quantitative-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154515.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">94</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> Effect of Drop Impact Behavior on Spray Retention</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassina%20Hafida%20Boukhalfa">Hassina Hafida Boukhalfa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Massinon"> Mathieu Massinon</a>, <a href="https://publications.waset.org/abstracts/search?q=Fr%C3%A9deric%20Lebeau"> Fréderic Lebeau</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Belhamra"> Mohamed Belhamra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Drop behaviour during impact affects retention. The increase of adhesion is usually seen as the objective when applying crop protection products, while bouncing and shattering are seen as detrimental to spray retention. However, observation of drop impacts using high speed shadow graphy shows that fragmentation can occur in Wenzel wetting regime. In this case, a part of the drop sticks on the surface, what contributes to retention. Using simultaneous measurements of drop impacts with high speed imaging and of retention with fluorometry for 3 spray mixtures on excised barley leaves allowed us to observe that about 50% of the drops fragmented in Wenzel state remain on the leaf. Depending on spray mixture, these impact outcomes accounted for 25 to 50% of retention, the higher contribution being correlated with bigger VMD (Volume Median Diameter). This contribution is non-negligible and should be considered when a modelling of spray retention process is performed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drop%20impact" title="drop impact">drop impact</a>, <a href="https://publications.waset.org/abstracts/search?q=retention" title=" retention"> retention</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorometry" title=" fluorometry"> fluorometry</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20speed%20imaging" title=" high speed imaging"> high speed imaging</a> </p> <a href="https://publications.waset.org/abstracts/47237/effect-of-drop-impact-behavior-on-spray-retention" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47237.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">381</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> Time Series Analysis of Radon Concentration at Different Depths in an Underground Goldmine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Theophilus%20Adjirackor">Theophilus Adjirackor</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Sam"> Frederic Sam</a>, <a href="https://publications.waset.org/abstracts/search?q=Irene%20Opoku-Ntim"> Irene Opoku-Ntim</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Okoh%20Kpeglo"> David Okoh Kpeglo</a>, <a href="https://publications.waset.org/abstracts/search?q=Prince%20K.%20Gyekye"> Prince K.

The detectors were installed in batches within four quarters. The measurements were carried out using LR115 solid-state nuclear track detectors. Statistical models are applied in the prediction and analysis of the radon concentration at various depths. The time series model predicted a positive relationship between the depth of the underground mine and the indoor radon concentration. Thus, elevated radon concentrations are expected at deeper levels of the underground mine, but the relationship was insignificant at the 5% level of significance with a negative adjusted R2 (R2 = – 0.021) due to an appropriate engineering and adequate ventilation rate in the underground mine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LR115" title="LR115">LR115</a>, <a href="https://publications.waset.org/abstracts/search?q=radon%20concentration" title=" radon concentration"> radon concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=rime%20series" title=" rime series"> rime series</a>, <a href="https://publications.waset.org/abstracts/search?q=underground%20goldmine" title=" underground goldmine"> underground goldmine</a> </p> <a href="https://publications.waset.org/abstracts/186013/time-series-analysis-of-radon-concentration-at-different-depths-in-an-underground-goldmine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186013.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">45</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">82</span> Risk Tolerance and Individual Worthiness Based on Simultaneous Analysis of the Cognitive Performance and Emotional Response to a Multivariate Situational Risk Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Jumelle">Frederic Jumelle</a>, <a href="https://publications.waset.org/abstracts/search?q=Kelvin%20So"> Kelvin So</a>, <a href="https://publications.waset.org/abstracts/search?q=Didan%20Deng"> Didan Deng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A method and system for neuropsychological performance test, comprising a mobile terminal, used to interact with a cloud server which stores user information and is logged into by the user through the terminal device; the user information is directly accessed through the terminal device and is processed by artificial neural network, and the user information comprises user facial emotions information, performance test answers information and user chronometrics.

However, current analysis is limited to the low frequency range. At medium and high frequencies, a rotational component appear in the field, masking the energy flow and make its understanding difficult or impossible. The objective of this work is to implement a methodology to filter out the rotational components of the structural intensity field in order to fully understand the energy flow in complex structures. The approach is based on the Helmholtz decomposition. It allows to decompose the structural intensity field into rotational, irrotational, and harmonic components. Only the irrotational component is needed to describe the net power flow from a source to a dissipative zone in the structure. The methodology has been applied on academic structures, and it allows a good analysis of the energy transfer paths. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=structural%20intensity" title="structural intensity">structural intensity</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20flow" title=" power flow"> power flow</a>, <a href="https://publications.waset.org/abstracts/search?q=helmholt%20decomposition" title=" helmholt decomposition"> helmholt decomposition</a>, <a href="https://publications.waset.org/abstracts/search?q=irrotational%20intensity" title=" irrotational intensity"> irrotational intensity</a> </p> <a href="https://publications.waset.org/abstracts/143536/vibration-propagation-in-structures-through-structural-intensity-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143536.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">178</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> Hedonistic Utilitarianism: The Strategic Use of Digital Media along the Online-Offline Continuum of Sexualised Violence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Kargel">Katharina Kargel</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Vobbe"> Frederic Vobbe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study examines how offenders targeting children and adolescents strategically use digital media when committing acts of sexualised violence along the online-offline continuum. Even offenders who are previously known to their victims use digital media extensively. The choice to instrumentalise digital media in order to initiate, threaten, exploit and humiliate victims demonstrates the rationale of offenders when committing acts of digitally supported violence. Through digital media, offenders can assume the power of interpretation over their victims’ situations. The ways in which digital media is used to commit violence along the online-offline continuum are a direct manifestation of the hedonistic utilitarianism demonstrated by offenders: a disposition characterised by the weighing of pleasures (“mental states”) and intrinsic value expected from using digital media against the risk of an outcome subjectively experienced as uncomfortable. Thus, sexualised violence using digital media goes beyond the traditional understanding of sexual online grooming. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sexualized%20violence" title="sexualized violence">sexualized violence</a>, <a href="https://publications.waset.org/abstracts/search?q=offender%20strategy" title=" offender strategy"> offender strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=grooming" title=" grooming"> grooming</a>, <a href="https://publications.waset.org/abstracts/search?q=children%20and%20adolescents" title=" children and adolescents"> children and adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative%20research" title=" qualitative research"> qualitative research</a>, <a href="https://publications.waset.org/abstracts/search?q=methodology" title=" methodology"> methodology</a> </p> <a href="https://publications.waset.org/abstracts/139518/hedonistic-utilitarianism-the-strategic-use-of-digital-media-along-the-online-offline-continuum-of-sexualised-violence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139518.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">221</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> Transient Free Laminar Convection in the Vicinity of a Thermal Conductive Vertical Plate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Bykalyuk">Anna Bykalyuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Fr%C3%A9d%C3%A9ric%20Kuznik"> Frédéric Kuznik</a>, <a href="https://publications.waset.org/abstracts/search?q=K%C3%A9vyn%20Johannes"> Kévyn Johannes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the influence of a vertical plate’s thermal capacity is numerically investigated in order to evaluate the evolution of the thermal boundary layer structure, as well as the convective heat transfer coefficient and the velocity and temperature profiles.

This paper reports on a descriptive case study of whole-of-institution curriculum reform at one regional Australian university, where more traditional 13-week semesters were replaced with a 6-week immersive block model drawing on active learning pedagogy. Based on a synthesis of literature in best practice HE pedagogy and principles, the case study draws on student performance data and senior management staff interviews (N = 5) to outline the key changes necessary for successful HE transformation to deliver increased student pass rates and retention. The findings from this case study indicate that an institutional transformation to an immersive block model requires both a considered change in institutional policy and process as well as the appropriate resourcing of roles, governance committees, technical solutions, and, importantly, communities of practice.

A deep learning paradigm is proposed for the purpose of mitigating the complexity of those systems. The proposed paradigm consists of a hybrid between the AdderNet deep learning paradigm and the Single Shot Detector (SSD) paradigm. The goal was to minimize multiplication operations numbers in the filtering layers within the proposed system and, hence, reduce complexity. Some standard machine learning technique, such as SVM, is also tested and compared to other deep learning systems. The data sets used for training and testing were either complete or filtered in order to remove the images with mall objects. The types of data were RGB or IR data.

We illustrate these applications in the section “Applications of Our Models to Other Tasks” with the “SIIM-ISIC Melanoma Classification Challenge 2020” [3]. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=weather%20simulation" title="weather simulation">weather simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=weather%20measurement" title=" weather measurement"> weather measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=weather%20classification" title=" weather classification"> weather classification</a>, <a href="https://publications.waset.org/abstracts/search?q=weather%20detection" title=" weather detection"> weather detection</a>, <a href="https://publications.waset.org/abstracts/search?q=style%20transfer" title=" style transfer"> style transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=Pix2Pix" title=" Pix2Pix"> Pix2Pix</a>, <a href="https://publications.waset.org/abstracts/search?q=CycleGAN" title=" CycleGAN"> CycleGAN</a>, <a href="https://publications.waset.org/abstracts/search?q=CUT" title=" CUT"> CUT</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20style%20transfer" title=" neural style transfer"> neural style transfer</a> </p> <a href="https://publications.waset.org/abstracts/194615/heuristic-of-style-transfer-for-real-time-detection-or-classification-of-weather-conditions-from-camera-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194615.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">3</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">74</span> An Analysis of a Relational Frame Skills Training Intervention to Increase General Intelligence in Early Childhood</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ian%20M.%20Grey">Ian M.

The hypothesis is that teaching young children to derive various relations between stimuli leads to increases in full-scale IQ scores of typically developing children. In the experimental group, sixteen 6-7-year-old children were exposed over six weeks to an intensive training intervention designed specifically for their age group. This training intervention, presented on a tablet, aimed to improve their understanding of the relations Same, Opposite, Different, contextual control over the concept of Sameness and Difference, and purely arbitrary derived relational responding for Sameness and Difference. In the control group, sixteen 6-7-year-old children interacted with KIBO robotics over six weeks. KIBO purports to improve cognitive skills through engagement with STEAM activities. Increases in full-scale IQ were recorded for most children in the experimental group, while no increases in full-scale IQ were recorded for the control group. These findings support the hypothesis that relational skills underlie many aspects of general cognitive ability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=early%20childhood" title="early childhood">early childhood</a>, <a href="https://publications.waset.org/abstracts/search?q=derived%20relational%20responding" title=" derived relational responding"> derived relational responding</a>, <a href="https://publications.waset.org/abstracts/search?q=intelligence" title=" intelligence"> intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=relational%20frame%20theory" title=" relational frame theory"> relational frame theory</a>, <a href="https://publications.waset.org/abstracts/search?q=relational%20skills" title=" relational skills"> relational skills</a> </p> <a href="https://publications.waset.org/abstracts/95579/an-analysis-of-a-relational-frame-skills-training-intervention-to-increase-general-intelligence-in-early-childhood" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95579.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">185</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">73</span> MindFlow: A Collective Intelligence-Based System for Helping Stress Pattern Diagnosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andres%20Frederic">Andres Frederic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present the MindFlow system supporting the detection and the diagnosis of stresses. The heart of the system is a knowledge synthesis engine allowing occupational health stakeholders (psychologists, occupational therapists and human resource managers) to formulate queries related to stress and responding to users requests by recommending a pattern of stress if one exists. The stress pattern diagnosis is based on expert knowledge stored in the MindFlow stress ontology including stress feature vector. The query processing may involve direct access to the MindFlow system by occupational health stakeholders, online communication between the MindFlow system and the MindFlow domain experts, or direct dialog between a occupational health stakeholder and a MindFlow domain expert. The MindFlow knowledge model is generic in the sense that it supports the needs of psychologists, occupational therapists and human resource managers. The system presented in this paper is currently under development as part of a Dutch-Japanese project and aims to assist organisation in the quick diagnosis of stress patterns. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=occupational%20stress" title="occupational stress">occupational stress</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20management" title=" stress management"> stress management</a>, <a href="https://publications.waset.org/abstracts/search?q=physiological%20measurement" title=" physiological measurement"> physiological measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=accident%20prevention" title=" accident prevention"> accident prevention</a> </p> <a href="https://publications.waset.org/abstracts/23744/mindflow-a-collective-intelligence-based-system-for-helping-stress-pattern-diagnosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23744.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">430</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">72</span> Functional Neural Network for Decision Processing: A Racing Network of Programmable Neurons Where the Operating Model Is the Network Itself</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Jumelle">Frederic Jumelle</a>, <a href="https://publications.waset.org/abstracts/search?q=Kelvin%20So"> Kelvin So</a>, <a href="https://publications.waset.org/abstracts/search?q=Didan%20Deng"> Didan Deng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we are introducing a model of artificial general intelligence (AGI), the functional neural network (FNN), for modeling human decision-making processes. The FNN is composed of multiple artificial mirror neurons (AMN) racing in the network. Each AMN has a similar structure programmed independently by the users and composed of an intention wheel, a motor core, and a sensory core racing at a specific velocity. The mathematics of the node’s formulation and the racing mechanism of multiple nodes in the network will be discussed, and the group decision process with fuzzy logic and the transformation of these conceptual methods into practical methods of simulation and in operations will be developed. Eventually, we will describe some possible future research directions in the fields of finance, education, and medicine, including the opportunity to design an intelligent learning agent with application in AGI. We believe that FNN has a promising potential to transform the way we can compute decision-making and lead to a new generation of AI chips for seamless human-machine interactions (HMI). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neural%20computing" title="neural computing">neural computing</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20machine%20interation" title=" human machine interation"> human machine interation</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20general%20intelligence" title=" artificial general intelligence"> artificial general intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20processing" title=" decision processing"> decision processing</a> </p> <a href="https://publications.waset.org/abstracts/130993/functional-neural-network-for-decision-processing-a-racing-network-of-programmable-neurons-where-the-operating-model-is-the-network-itself" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130993.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">125</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">71</span> Vitamin D Deficiency and Insufficiency in Postmenopausal Women with Obesity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vladyslav%20Povoroznyuk">Vladyslav Povoroznyuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Musiienko"> Anna Musiienko</a>, <a href="https://publications.waset.org/abstracts/search?q=Nataliia%20Dzerovych"> Nataliia Dzerovych</a>, <a href="https://publications.waset.org/abstracts/search?q=Roksolana%20Povoroznyuk"> Roksolana Povoroznyuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Oksana%20Ivanyk"> Oksana Ivanyk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Deficiency and insufficiency of Vitamin D is a pandemic of the 21<sup>st</sup> century. Obesity patients have a lower level of vitamin D, but the literature data are contradictory. The purpose of this study is to investigate deficiency and insufficiency vitamin D in postmenopausal women with obesity. We examined 1007 women aged 50-89 years. Mean age was 65.74±8.61 years; mean height was 1.61±0.07 m; mean weight was 70.65±13.50 kg; mean body mass index was 27.27±4.86 kg/m<sup>2</sup>, and mean 25(OH) D levels in serum was 26.00±12.00 nmol/l. The women were divided into the following six groups depending on body mass index: I group – 338 women with normal body weight, II group – 16 women with insufficient body weight, III group – 382 women with excessive body weight, IV group – 199 women with obesity of class I, V group – 60 women with obesity of class II, and VI group – 12 women with obesity of class III. Level of 25(OH)D in serum was measured by means of an electrochemiluminescent method - Elecsys 2010 analyzer (Roche Diagnostics, Germany) and cobas test-systems. 34.4% of the examined women have deficiency of vitamin D and 31.4% insufficiency. Women with obesity of class I (23.60±10.24 ng/ml) and obese of class II (22.38±10.34 ng/ml) had significantly lower levels of 25 (OH) D compared to women with normal body weight (28.24±12.99 ng/ml), p=0.00003. In women with obesity, BMI significantly influences vitamin D level, and this influence does not depend on the season. <p class="card-text"><strong>Keywords:</strong> <a
