A High-Efficiency QR Flyback DC–DC Converter with Reduced Switch Voltage Stress Realized by Applying a Self-Driven Active Snubber (SDAS)
Authors: Yoo Jeong-Sang , Baek Jong-Ok , Ahn Tae-Young 
Published: January 2023

In this paper, a QR flyback converter using a self-driven active snubber (SDAS) was proposed to solve the problem of voltage surge in the switch of QR flyback converters. In the proposed converter, the SDAS consisting of a clamping capacitor and an active switch can be configured in parallel with the main switch or transformer to reduce the voltage surge in the switch. To confirm the steady-state characteristics of the QR flyback converter to which the proposed SDAS is applied, equivalent circuits for each state were constructed, and the equations and characteristics for each state were determined. A 60 W class small AC–DC adapter was constructed to confirm the effectiveness of the proposed converter and the control circuit method, and the experimental results were analyzed. The size of the experimental AC–DC adapter was 74×29×23 mm, and it had a high power density of 20 W/in3 or more. The experimental circuit was limited to the high power conversion efficiency of up to 91.56%, and the maximum voltage surge in the switch was approximately 450 V. One of the reasons for such high efficiency is the SDAS circuit, which sufficiently reduces the voltage surge of the QR flyback switch, compared with the RCD clamp circuit, and does not consume power in principle.

Aim. To study the indicators and regional specifics of morbidity associated with temporary disability in the Subjects of the Far Eastern Federal District (FEFD) of Russia.Materials and methods. A descriptive epidemiological study was performed based on retrospective data on the morbidity associated with temporary disability of the working population in FEFD as of January 01, 2021. A unified inter-agency information and statistical system was used to study the indicators of temporary disability (TD), including the number of TD cases per 100 employees and the number of TD days per 100 employees during 2005–2020. The methods of descriptive statistics were applied to differentially calculate the average annual indicators for the periods of 2005–2014 and 2015–2019 due to the adoption of the Rosstat order No. 723 dated December 25, 2014.Results. The average long-term value of the indicators of morbidity associated with temporary disability in most FEFD subjects was found to be statistically significantly higher than that in the entire Russian Federation, with higher values o bserved in 2005–2014 compared to 2015–2019. The indicators of morbidity associated with temporary disability demonstrated a more stable trend during 2015–2019. The indicators for 2020 were statistically higher than for 2015–2019, largely due to the COVID-19 pandemics.Conclusions. In view of the specific nature of the main economic sectors in FEFD (shift and seasonal work), as well as the lack of a developed social, road transport, and engineering infrastructure, data on temporary disability of the working population (including migrants) should be continuously monitored. The results obtained at this research stage can be used to develop optimal measures aimed at protecting the health of people living in the Far East of Russia.

Authors: Chen Cindy Y. , Donga Prina , Campbell Alicia K. , Taiwo Babafemi 
Published: January 2023

Background: With advances in antiretroviral therapy (ART), people with HIV infection are living longer. Pre-exposure prophylaxis (PrEP) to reduce HIV infection risk continues to be underutilized in high-risk individuals. Recent data on economic burden for patients with newly diagnosed HIV-1 or initiated with PrEP are limited. Objectives: To assess characteristics, healthcare resource utilization (HRU), and costs among adults and adolescents either with newly diagnosed HIV-1 or initiated with PrEP. Methods: This retrospective observational study utilized data from the IBM MarketScan® Commercial Claims and Encounters database. Adults with newly diagnosed HIV-1 or those initiated with PrEP were included (index date was the first HIV diagnosis or PrEP prescription, respectively, between January 1, 2016, and April 30, 2021). Corresponding cohorts of adolescents were considered exploratory. Descriptive analyses were conducted to assess baseline demographics and clinical characteristics, and all-cause and HIV-related HRU and costs per patient per month (PPPM) during follow-up. Results: Data from 18 154 adults and 220 adolescents with newly diagnosed HIV and 34 123 adults and 175 adolescents initiated with PrEP were included. Approximately 70% of adolescents and 9% of adults receiving PrEP were female. Baseline depression/anxiety was present in 16.1% and 24.6% of adults and 14.5% and 45.1% of adolescents in the HIV and PrEP cohorts, respectively. Substance abuse in the HIV and PrEP cohorts, respectively, was reported in 10.1% and 7.0% of adults, and 2.7% and 17.7% of adolescents. During follow-up, among adults with newly diagnosed HIV, mean (SD) total all-cause and HIV-related PPPM costs were $2657 ($5954) and $1497 ($4463), respectively; pharmacy costs represented 47% of all-cause costs and 67% of HIV-related costs, but only 37% of patients had an HIV-related prescription. All-cause costs PPPM for adults with PrEP were $1761 ($1938), with pharmacy costs accounting for 71%. Conclusions: Despite advances in ART, patients with newly diagnosed HIV and at-risk patients receiving PrEP continue to incur HRU costs. The chronic nature of HIV warrants further exploration of factors contributing to disease burden and opportunities to improve prevention strategies.
Więzi z miejscem – narracyjne (re)konstruowanie tożsamości w rodzinie po-jugosłowiańskiej
Authors: Ligus Rozalia 
Published: January 2023

Jest to kolejny artykuł z cyklu, w którym przedstawiono wyniki pracy analitycznej oraz interpretacyjnej z realizacji projektu „Migrujące biografie – potomkowie reemigrantów z Bośni w procesie rekonstruowania tożsamości. Pedagogiczne atrybuty przekazu międzygeneracyjnego w świetle historii życia”. Inspiracją do podjęcia badań były tożsamościowe identyfikacje mieszkańców powiatu bolesławieckiego na Dolnym Śląsku, którzy w 2018 r. mówili o sobie „My, Polacy z Jugosławii”, choć wielu z nich nigdy nie było w Jugosławii, a kraju tego od 1995 r. nie ma na mapie świata. W tekście dokonano analizy procesu konstytuowania się tożsamości na podstawie znaczenia, jakie jedna z uczestniczek badań, Barbara, nadała przestrzeni i miejscom, które dla niej stały się zarówno źródłem wiedzy na temat własnej tożsamości, jak i inspiracją do podejmowania aktywności ukierunkowanej na zmianę otaczającej ją przestrzeni publicznej.Odwołując się do opisu miejsca jako przestrzeni geograficznej, korzystałam z dwóch podejść teoretycznych. Pierwsze z nich reprezentuje socjolożka Martina Löw, która proponuje spojrzenie na przestrzeń z perspektywy ponowoczesnej. Drugie zaś opracowane jest przez dwóch psychologów społecznych i środowiskowych, tj. Leilę Scanell i Roberta Gifforda. Te dwie propozycje teoretyczne traktuję jako przykłady narzędzi interpretacyjnych, które z jednej strony ułatwiają zrozumienie możliwych sposobów odczytywania więzi człowieka z miejscem, przestrzenią materialną i symboliczną oraz uwzględniają emocjonalne, kognitywne i społeczne wyznaczniki relacji z przestrzenią, a z drugiej – pozwalają na rozpoznanie siły i znaczenia związku z przestrzenią, która staje się rdzeniem biograficznie konstytuowanej tożsamości.
Assessment of Stress Shielding around a Dental Implant for Variation of Implant Stiffness and Parafunctional Loading using Finite Element Analysis
Authors: Ishak_ Muhammad , Daud Ruslizam , Noor Siti , Noor Fazliah Mohd , Khor Chu Yee , Roslan Husniyati 
Published: January 2023

Purpose
The aim of this study was to evaluate the mechanical stimuli transfer at the bone-implant interface via stress and strain energy density transfer parameters. This study also aimed to investigate the effect of different implant stiffness and parafunctional loading values on the defined mechanical stimuli transfer from the implant to the surrounding bone.
Methods
A three-dimensional finite element model of two-piece threaded dental implant with internal hexagonal connection and mandibular bone block was constructed. Response surface method through face-centred central composite design was applied to examine the influence of two independent factors variables using three levels. The analysis model fitted to a second-order polynomial equation to determine the response values.
Results
The results showed that the implant stiffness was more effective than the horizontal load value in increasing the stress and strain energy density transfers. The interaction between both factors was significant in decreasing the likelihood of bone resorption. Decreasing the implant stiffness and horizontal load value led to the increased stress transfer and unexpected decrease in the strain energy density except at the minimum level of the horizontal load. The increase in the implant stiffness and horizontal load value (up to medium level) have increased the strain energy transfer to the bone.
Conclusions
The stress and strain energy density were transferred distinctively at the bone-implant interface. The role of both implant stiffness and parafunctional loading is important and should be highlighted in the pre-operative treatment planning and design of dental implant.

A Framework for Obtaining Accurate Posteriors of Strong Gravitational Lensing Parameters with Flexible Priors and Implicit Likelihoods Using Density Estimation
Authors: Legin Ronan , Hezaveh Yashar , Perreault-Levasseur Laurence , Wandelt Benjamin 
Published: January 2023

Abstract
We report the application of implicit likelihood inference to the prediction of the macroparameters of strong lensing systems with neural networks. This allows us to perform deep-learning analysis of lensing systems within a well-defined Bayesian statistical framework to explicitly impose desired priors on lensing variables, obtain accurate posteriors, and guarantee convergence to the optimal posterior in the limit of perfect performance. We train neural networks to perform a regression task to produce point estimates of lensing parameters. We then interpret these estimates as compressed statistics in our inference setup and model their likelihood function using mixture density networks. We compare our results with those of approximate Bayesian neural networks, discuss their significance, and point to future directions. Based on a test set of 100,000 strong lensing simulations, our amortized model produces accurate posteriors for any arbitrary confidence interval, with a maximum percentage deviation of 1.4% at the 21.8% confidence level, without the need for any added calibration procedure. In total, inferring 100,000 different posteriors takes a day on a single GPU, showing that the method scales well to the thousands of lenses expected to be discovered by upcoming sky surveys.

La dignité de la créature au miroir de l’animal. Droit fondamental ou principe général ?
Authors: Favre Brian 
Published: January 2023

La dignité de la créature est un concept juridique flou, mais non pas vide. Elle fixe un programme ambitieux : le respect du vivant par une communauté humaine et une responsabilité à son égard. Malgré ses 30 ans, cette innovation du droit helvétique est encore en quête d’une concrétisation juridique. Afin d’envisager plus précisément les formes que cette dignité du vivant pourrait prendre à l’avenir, il est utile de lui tendre un miroir grossissant : celui de l’animal. C’est en effet sous la guise de la dignité animale que se laissent aujourd’hui le mieux percevoir les deux voies possibles de la concrétisation de ce concept innovant (droit subjectif ou principe). L’alternative mérite qu’on s’y arrête, car elle trace sans doute les contours de la société multispécifique de demain.
Travail vivant et dignité des animaux de ferme
Authors: Porcher Jocelyne 
Published: January 2023

À partir des années 2000, dans le fil de l’inscription de la notion de « dignité de la créature » dans la constitution suisse, des réflexions ont émergé à propos de la « dignité de l’animal ». Aujourd’hui, il semble que la dignité des animaux de ferme soit plus précaire que jamais. J’argumente ce constat en lien avec le développement de l’agriculture cellulaire, notamment de la « viande cultivée » et l’expansion du travail mort dans l’industrie. En élevage, le respect de la dignité des animaux se manifeste dans les pratiques des éleveurs et dans les modes de relations avec la nature qu’elles permettent. À l’inverse du travail mort porté par l’agriculture industrielle et les biotechnologies, le travail en élevage reste un travail vivant, pour la vie et pour la dignité des humains et des animaux.
