Field Programmable Gate Array-Based Acceleration Algorithm Design for Dynamic Star Map Parallel Computing
Authors: Cui Bo , Wang Lingyun , Li Guangxi , Ren Xian 
Published: March 2024

The dynamic star simulator is a commonly used ground-test calibration device for star sensors. For the problems of slow calculation speed, low integration, and high power consumption in the traditional star chart simulation method, this paper designs a FPGA-based star chart display algorithm for a dynamic star simulator. The design adopts the USB 2.0 protocol to obtain the attitude data, uses the SDRAM to cache the attitude data and video stream, extracts the effective navigation star points by searching the starry sky equidistant right ascension and declination partitions, and realizes the pipelined displaying of the star map by using the parallel computing capability of the FPGA. Test results show that under the conditions of chart field of view of Φ20° and simulated magnitude of 2.0∼6.0 Mv, the longest time for calculating a chart is 72 μs under the clock of 148.5 MHz, which effectively improves the chart display speed of the dynamic star simulator. The FPGA-based star map display algorithm gets rid of the dependence of the existing algorithm on the computer, reduces the volume and power consumption of the dynamic star simulator, and realizes the miniaturization and portable demand of the dynamic star simulator.

Published: March 2024

Mosquitoes are the most notorious arthropod vectors of viral and parasitic diseases for which approximately half the world’s population, ~4,000,000,000, is at risk. Integrated pest management programs (IPMPs) have achieved some success in mitigating the regional transmission and persistence of these diseases. However, as many vector-borne diseases remain pervasive, it is obvious that IPMP successes have not been absolute in eradicating the threat imposed by mosquitoes. Moreover, the expanding mosquito geographic ranges caused by factors related to climate change and globalization (travel, trade, and migration), and the evolution of resistance to synthetic pesticides, present ongoing challenges to reducing or eliminating the local and global burden of these diseases, especially in economically and medically disadvantaged societies. Abatement strategies include the control of vector populations with synthetic pesticides and eco-friendly technologies. These “green” technologies include SIT, IIT, RIDL, CRISPR/Cas9 gene drive, and biological control that specifically targets the aquatic larval stages of mosquitoes. Regarding the latter, the most effective continues to be the widespread use of Lysinibacillus sphaericus (Ls) and Bacillus thuringiensis subsp. israelensis (Bti). Here, we present a review of the health issues elicited by vector mosquitoes, control strategies, and lastly, focus on the biology of Ls and Bti, with an emphasis on the latter, to which no resistance has been observed in the field.
AMPK-SP1–Guided Dynein Expression Represents a New Energy-Responsive Mechanism and Therapeutic Target for Diabetic Nephropathy
Authors: Williquett Jillian , Allamargot Chantal , Sun Hua 
Published: March 2024

Key Points

AMP kinase senses diabetic stresses in podocytes, subsequently upregulates specificity protein 1–mediated dynein expression and promotes podocyte injury.Pharmaceutical restoration of dynein expression by targeting specificity protein 1 represents an innovative therapeutic strategy for diabetic nephropathy.

Background
Diabetic nephropathy (DN) is a major complication of diabetes. Injury to podocytes, epithelial cells that form the molecular sieve of a kidney, is a preclinical feature of DN. Protein trafficking mediated by dynein, a motor protein complex, is a newly recognized pathophysiology of diabetic podocytopathy and is believed to be derived from the hyperglycemia-induced expression of subunits crucial for the transportation activity of the dynein complex. However, the mechanism underlying this transcriptional signature remains unknown.

Methods
Through promoter analysis, we identified binding sites for transcription factor specificity protein 1 (SP1) as the most shared motif among hyperglycemia-responsive dynein genes. We demonstrated the essential role of AMP-activated protein kinase (AMPK)–regulated SP1 in the transcription of dynein subunits and dynein-mediated trafficking in diabetic podocytopathy using chromatin immunoprecipitation quantitative PCR and live cell imaging. SP1-dependent dynein-driven pathogenesis of diabetic podocytopathy was demonstrated by pharmaceutical intervention with SP1 in a mouse model of streptozotocin-induced diabetes.

Results
Hyperglycemic conditions enhance SP1 binding to dynein promoters, promoted dynein expression, and enhanced dynein-mediated mistrafficking in cultured podocytes. These changes can be rescued by chemical inhibition or genetic silencing of SP1. The direct repression of AMPK, an energy sensor, replicates hyperglycemia-induced dynein expression by activating SP1. Mithramycin inhibition of SP1-directed dynein expression in streptozotocin-induced diabetic mice protected them from developing podocytopathy and prevented DN progression.

Conclusions
Our work implicates AMPK-SP1–regulated dynein expression as an early mechanism that translates energy disturbances in diabetes into podocyte dysfunction. Pharmaceutical restoration of dynein expression by targeting SP1 offers a new therapeutic strategy to prevent DN.

This research was conducted to determine the diversity of ferns (Pteridophyta). This research was conducted in the Ajaobaki Protected Forest, Ajaobaki Village, North Mollo District, South Central Timor Regency, East Nusa Tenggara Province. It was carried out for 1 month from March to April 2021. This study used a purposive sampling, survey, and transect method with data analysis using qualitative descriptive analysis and quantitative descriptive analysis. The data was processed using the Shannon Wiener (H’) diversity index formula. The results showed that environmental and ecosystem factors in the Ajaobaki protected forest area was very good for ferns silviculture. But some factors cause damage to the Ajaobaki protected forest area which can experience extinction in ferns caused by humans and livestock. There were 11 species of ferns found in the sampling plot in the Ajaobaki Protected Forest, Ajaobaki Village, consisting of 4 ferns that live on the ground (terrestrial) and 7 ferns that live on trees (epifit). The most common ferns found were Devalia Canariensis with 540 species and the least found was Drynaria Quercifolia ferns with 3 species. The level of diversity of fern species was calculated using the Shannon winner index of 1.79 (H’) for all species with moderate diversity (1≤H’≤3).

Polymorphic transformation from metastable β to stable α phase in MnTe flake
Authors: Mori Shunsuke , Sutou Yuji 
Published: March 2024

Abstract
Manganese telluride (MnTe) is an intriguing polymorphic semiconductor. Among them, the metastable β-MnTe phase, characterized by a wurtzite-type structure, has been successfully fabricated as a sputtered film on substrates. However, bulk or free-standing β-MnTe without substrates has never been realized. In this study, we fabricated a β-MnTe flake using a lift-off process. Notably, the X-ray diffraction patterns of the flake sample approached the predicted peak positions of bulk β-MnTe, indicating strain relaxation. This study represents a pioneering experimental success in demonstrating a bulk-like β-MnTe. Furthermore, we conducted thermal analyses associated with the β→α transformation through differential scanning calorimetry. The β-MnTe flake exhibited a lower transformation temperature than films, suggesting diminished thermal stability of the β phase. The enthalpy change was quantitatively determined as −45.1 kJ mol−1, which arises from the substantial volume change. These experimental demonstrations are expected to contribute to the application of free-standing β-MnTe in optoelectronic and piezoelectric fields.
Anomalous deformation behavior of Ag nanowires on Au electrode in low-temperature environments
Authors: Watanabe Yuichi , Kuribara Kazunori , Nomura Ken-ichi 
Published: March 2024

Abstract
We discovered that Ag nanowires (AgNWs) on an Au electrode exhibited an anomalous deformation behavior despite a low-temperature environment of 65 °C. Most AgNWs on the Au electrode were deformed after heating. In contrast, AgNWs on the Cr and Ag electrodes exhibited a few changes and maintained their initial shape. The deformation behavior of AgNWs on metal electrodes has not yet been reported and is currently difficult to explain using known processes such as diffusion and alloying. Nonetheless, they evidently depend on the electrode material. The findings of this study are crucial for the design of AgNW-based electronic devices.
Análise de conteúdo da produção científica brasileira sobre produtos orgânicos (2010-2021)
Authors: Vilhena Luciana Girão de , Braga Francisco Laercio Pereira , Lima Filipe Augusto Xavier 
Published: March 2024

O objetivo deste estudo foi realizar uma revisão do conteúdo sobre produtos orgânicos no contexto brasileiro entre 2010 e 2021, na perspectiva da análise lexical. No percurso metodológico, realizou-se o levantamento de trabalhos científicos nacionais, publicados nas plataformas Spell e Periódicos Capes, no período delimitado, o que possibilitou selecionar 43 artigos. Em seguida, analisou-se o conteúdo dos artigos selecionados em abordagem quantitativa e qualitativa, por meio do software Iramuteq. Os resultados mostraram que o corpus textual foi subdividido em classes de 1 a 4. Por abordarem assuntos complementares, as classes 2 e 3 têm maior proximidade entre si, enquanto a 1 e a 4 aparecem de forma mais independente e isolada. Em geral, notam-se insights importantes que enfatizam a necessidade de incentivar a agricultura orgânica para reduzir a poluição, promover a sustentabilidade e atender às preocupações ambientais e de saúde dos consumidores. Os resultados levam a deduzir que trabalhos e discussões relacionados a produtos orgânicos – que englobam as temáticas desenvolvimento sustentável, políticas públicas e feiras verdes/agroecológicas, são ainda incipientes na agricultura familiar, o que indica a necessidade de pesquisas adicionais à literatura.

Published: March 2024

O objetivo deste artigo foi caracterizar o perfil socioeconômico de pecuaristas familiares da Campanha Gaúcha inseridos em processos inovativos e analisar mudanças, nas rotinas das atividades, nas unidades de produção da pecuária familiar. Para isso, foi desenvolvido um estudo de casos múltiplos em Alegrete e Santana do Livramento, na Campanha Gaúcha. Como a pecuária familiar tem sido distanciada de processos inovativos e de mudanças, foi necessário, em um primeiro momento, aproximá-la e reconhecer os participantes da pesquisa como pecuaristas familiares. Parte do esforço possibilita, também, rever ou ampliar a compreensão sobre processos inovativos, os quais podem ser identificados nos relatos sobre as mudanças de rotinas, trajetórias e experiências dos participantes. Assim, reconhece-se uma faceta pouco discutida da pecuária familiar: os pecuaristas familiares inovativos. Abre-se, assim, espaço para novas discussões, que consideram as dinâmicas e os contextos de categorias sociais como pontos de partida para análise e compreensão de suas demandas.
Computational Approach on Convective-Magneto Trihybrid Nanoflow with Space Dependent Energy Source/Sink: Drug Delivery
Authors: Vinothkumar B , Poornima T 
Published: March 2024

Iron oxide, Silver, Aluminium oxide, these nanoparticles individually or combined help in drug delivery especially aluminium oxide nanofluid used in an anti-blood pressure drug called 'Telmisartan'. Alumina and silver particles are used in manufacturing nanocomposites which have more antimicrobial properties. This is the reason for the current study of ternary nanofluids natural convective flow and efficacy of energy transfer in a bi-directionally sheet. Currently, ternary nanofluids (Fe3O4, Ag, Al2O3) are being taken for analysis. Usual water (H2O) is the conventional base fluid. Two different combinations of ternary nanofluids are used to get the average heat transfer rate, mixture ratios (Fe3O4 + Ag) and (Fe3O4 + Ag + Al2O3) when subjected to a variety of physical influences, including thermal radiation, magnetic fields, heat production and absorption, and nanoparticle volume amount. It is possible to solve the developed set of equations numerical results using the Keller box (finite differences) method with the help of MATLAB programming. This method helps in solving higher order partial differential equation (PDEs) to ordinary differential equation (ODEs). The investigations findings demonstrated that the ternary hybrid nanofluids specific heat capacity is directly impacted by temperature. Numerical solutions for Nusselt number, velocity profile, skin friction coefficient, temperature profiles have represented with the help of graphs and tables. The ternary hybrid nanoflow (Fe3O4 + Ag + Al2O3/H2O) transmits more energy for increasing volume fractions, comparing to the hybrid nanofluid (Fe3O4 + Ag/H2O). The study reveals the fact that metal oxides transfer more heat from the system than that of metals. The estimated error of heat transfer rate is higher in alumina nanoflow followed by silver and iron oxide nanofluid flows. The streamlines are equally spaced, but the energy flow amount is higher for the case M, S = 1 than M, S = 2. But in the case of stretching ratio parameter, the amount energy flow in α = 0.5 > α = 1.0. An equal amount of energy flow is observed for varied Biot number.

Published: March 2024

In unterschiedlichen Bereichen der Lebensmittelindustrie – sowie in vielen anderen Branchen – werden Klebebänder zum ein- oder beidseitigen Verschließen von Verpackungen, meist Faltschachteln, genutzt. Oftmals befinden sich Arbeitsplätze bei der Aufgabe beziehungsweise Entnahme von Kartonagen oder im Umfeld von Verpackungsmaschinen. Die hierbei auftretenden Pegel liegen oberhalb des unteren Auslösewertes (Tages-Lärmexpositionspegel LEX,8h = 80 dB(A)) der Lärm- und Vibrations-Arbeitsschutzverordnung [1]. Ein Kooperationsprojekt des Instituts für Arbeitsschutz (IFA) der DGUV und der Berufsgenossenschaft Nahrungsmittel und Gastgewerbe (BGN) gingen der Frage nach, inwieweit Unterschiede bei der Schallemission von Klebebändern vorhanden sind und ob diese zur Lärmminderung in die betriebliche Praxis gespiegelt werden können. Dazu wurden 13 Klebebänder mit verschiedenen Spezifikationen im Laborumfeld und in situ im Arbeitsalltag verschiedener Unternehmen der Nahrungsmittelindustrie untersucht.

Summary Adhesive tapes are used in various areas of the food industry – and in many other sectors – to seal one or both sides of packaging, usually folding boxes. Workstations are often located where cardboard boxes are loaded or unloaded or in the vicinity of packaging machines. The levels occurring here are above the lower action value (daily noise exposure level LEX,8h = 80 dB(A)) of the Noise and Vibration Occupational Safety and Health Ordinance [1]. A cooperation project between the Institute for Occupational Safety and Health of the German Social Accident Insurance (IFA) and the German Social Accident Insurance Institution for the food and catering industry (BGN) investigated the extent to which differences in the noise emissions of adhesive tapes are exist and whether these can be used in operational practice to reduce noise. For this purpose, 13 adhesive tapes with different specifications were analysed in the laboratory environment and with practical orientation in the day-to-day work of several companies in the food industry.

La forme de la relation utilisateur-constructeur joue considérablement sur la pertinence, la qualité d’un modèle marketing et, par conséquent, sur les chances qu’il a d’être utilisé. Le Web constitue une réelle opportunité de co-modélisation à tous les stades du processus de développement de nouveaux modèles ou d’amélioration des modèles existants. Un modèle de satisfaction-rétention avec double segmentation de la base clients et prise en compte des « switching - costs » est lancé dans ce but sur le Web.
Les bandeaux publicitaires sur Internet : mesures d’efficacité
Authors: Onnein-Bonnefoy Carole 
Published: March 2024

Cet article se propose de reconsidérer la question de la définition et de la mesure de l’efficacité des bandeaux publicitaires sur Internet, à notre avis trop réduite. Il s’articule autour de trois parties : la définition des objectifs des bandeaux publicitaires (essentiellement un objectif comportemental), la présentation des outils de mesure de l’audience publicitaire (le PAP) et de l’efficacité publicitaire (le taux de clics) et enfin la proposition d’une définition plus large de l’efficacité des bandeaux publicitaires. En effet, le taux de clics ne nous semble pas refléter à lui seul l’impact des bandeaux et nous pensons qu’il est indispensable de prendre en compte l’ensemble des réactions affectives et cognitives suscitées par les bandeaux.
