Published: December 2022

The use of ultra-wideband (UWB) in target detection, radar and wireless connectivity, specifically in the medical world, has attracted a lot of attention. The concept that the IR-UWB system does not necessarily require carrier signals is one of its most appealing features. IR-UWB can transmit information using short Gaussian monocycle pulses. In light of these advantages, this paper proposes a novel UWB transmitter system which consists of UWB signal generating circuits and UWB antenna, which work together to create entire UWB transmitter. It is based on impulses and has a simple architecture with low power consumption. The proposed transmitter is realized in Cadence tools with 90nm CMOS technology and proposed UWB antenna is simulated using Advanced Design System (ADS) simulator software. In addition, the transmitter circuit and the antenna are co-simulated using ADS software. The illustrated UWB transmitter uses a low-power supply and generates pulse amplitude with pulse duration of for the Gaussian monocycle pulse. Due to its increased output voltage swing and reduced power consumption when comparing to other circuits, the proposed architecture is functional and suitable for use in short-range wireless networks and medical applications.

Published: December 2022

Biosurfactants have been shown to have a variety of other agricultural applications. Antimicrobial activity is a desirable property in a variety of biosurfactants. Several biosurfactants produced from bacteria have antibacterial activity against plant diseases, making them a promising biocontrol molecule for ensuring agricultural sustainability in the long run. The purpose of this research was to characterize biosurfactant produced at different carbon source by biosurfactant-producing bacterial strains isolated from contaminated soapstock sediment, as well as its antifungal properties. Biosurfactant-producing bacteria were isolated from soapstock-contaminated soil which bacteria were selected by using drop collapse and oil displacement tests. Twelve isolates reduced surface tension of culture broth from 50 to 31 - 43 mN/m. According to 16S rRNA sequence analysis, these isolates belong to 8 different genera (Acinetobacter, Citrobacter, Enterobacter, Klebsiella, Pantoea, Pseudomonas, Stenotrophomonas and Xanthomonas). The supernatant of Pseudomonas aeruginosa A4 grown in MSM supplemented with soapstock was the most effective biosurfactant against Aspergillus flavus F2, Aspergillus niger F14, Cunninghamella bertholletiae F1 and Rhizopus oryzae F5, inhibiting mycelium growth by 54, 61 59 and 50 %, respectively. The extract substance inhibited spore germination against A. flavus F2 and R. oryzae F5 with a minimum inhibitory concentration of 2.75 mg/mL. TLC, FT-IR, ESI-MS and GC-MS analysis demonstrated that the mono-rhamnolipids and di-rhamnolipids had the same 3-hydroxy fatty acid composition of C8, C10 and C12. Overall, the biosurfactant-producing strains identified in this investigation show promise for future development and application in cost-effective industrial-scale biotechnological processes.
HIGHLIGHTS

Biosurfactant producing bacteria were isolated from soapstock contaminated soil
The supernatant of Pseudomonas aeruginosa A4 grown in MSM supplemented with soapstock was the most effective biosurfactant against plant pathogenic fungi
Biosurfactant from Pseudomonas aeruginosa A4 was identified as rhamnolipid comprising of both mono and di-rhamnolipid congeners

Published: December 2022

Background: At seasonal tourist destinations like Shimla, rooms may remain vacant and unoccupied during lean peri ods. To add on, pandemic has already shut many small lodging facilities. Objective: The aim of this study is to improve our understanding of how homestay activities can contribute to revitalize sustainable tourism trends in Shimla, the study assumes particular importance in a period of economic crisis characterized by post covid trauma. Methodology: A survey was conducted in Shimla after first wave of corona virus from September 20 to December 20 as soon as the travel restrictions were uplifted. The travel and accommodation preferences of tourists were observed and found to be shifting towards less frequently visited places avoiding mass tourism. To highlight the role of homestays in reviving these tourism trends, three objectives were identified. Two separate questionnaires were developed to get the quantitative and qualitative data for this research. The data was tabulated and evaluated using SPSS tool. Results: The findings presented the analysed profile of the potential homestay operators as well as visitors seeking homestay tourism. It also reports the motivations, expectation and experience of the tourists regarding various aspects of homestay. Conclusion: Homestays can act as potential vital tool in reviving tourism.

Published: December 2022

Objetivo: Determinar el efecto del calentamiento activo sobre el rendimiento contrarreloj en nadadores por medio de una revisión sistemática y metaanálisis. Métodos: Se realizó una búsqueda de literatura en nueve bases de datos electrónicas. Se calculó el tamaño del efecto (TE) individual aplicando un diseño de comparación entre grupos y se resumieron los resultados utilizando el modelo de efectos aleatorios (REML), considerándose estadísticamente significativos los valores de p<0.05 y los intervalos de confianza del 95% no superpuestos (IC95%). Se calculó la heterogeneidad e inconsistencia mediante las pruebas Q de Cochran e I2, de forma respectiva. Para evaluar sesgo, se realizó el gráfico de embudo (funnel plot) y la prueba de Egger. Resultados: Un total de 11 artículos fueron incluidos en este análisis. El TE global fue trivial y no significativo (TE= -0.125; IC95%= -0.273, 0.022; p= 0.096; Q = 18.268, p = 0.690, I2= 0.00%), demostrándose que no existe efecto del calentamiento activo sobre el rendimiento deportivo en natación. Conclusión: El calentamiento activo no demuestra mejorar el rendimiento en natación, una vez que es comparado con una condición de control donde no se calienta. Sin embargo, se recomienda mantener el análisis de las respuestas individuales para obtener el mejor rendimiento de cada atleta.

Purpose. The purpose of the present study is to examine the determinants of the financial performance of the Slovak agricultural companies.
Methodology / approach. Bibliometric analysis was applied to analyze the literature, the results of the review were visualized using VOSviewer software. Panel data regression analysis, which was carried out using the GRETL software, was chosen to be the main research method for analyzing the influence of determinants on financial performance measures. 527 Slovak agricultural companies’ activity over the period 2015–2019 was chosen as the object of the study. The analysis is carried out based on the publicly available financial information (financial statements, management reports, official company websites) and information available in the “FinStat” database. Regression analysis was performed according to four developed models based on the use of four different dependent variables (Return on Assets (ROA), Net Profit Margin (NPM), Return on Equity (ROE), Return on Sales (ROS)) and 10 independent variables same for all the models (Leverage, Long-Term Debt to Assets, Short-Term Debt to Assets, Debt to Equity, Capital intensity, Tangibility of Assets, Current Ratio, Size, Dummy variable for type of ownership, Dummy variable for legal form). Fixed Effects Method was chosen as an estimate panel data parameter on the base of F-statistics test, Breusch-Pagan test, and Hausman test use.
Results. The obtained results confirm the hypothesis about the existence of a distinctive impact of financial performance determinants due to the availability of the specific environment and features typical for the Slovak agricultural sector. None of the independent variables applied has a significant effect simultaneously on Models 1–4. We observed a negative significant impact at the 1 % level of l_Size on ROA and ROE of the Slovak agricultural companies. CapInt also has a negative significant impact on NPM and ROE. DtoE is found to have a positive impact on ROE. The complete lack of influence of AsTang in determining financial performance was revealed. The used dummy variables (DVTO, DVLF) were excluded from the composition of Models 1–4 during the regression analysis due to the availability of exact collinearity.
Originality / scientific novelty. The uniqueness of the present study is that we identify the impact of the financial performance determinants specifically for the Slovak agricultural companies considering the specifics of the Slovak agricultural market in the context of the current problems in the sector of the economy being investigated.
Practical value / implications. The obtained results can be used to improve the management decisions of the Slovak agricultural companies, to critically evaluate the state policy in the agricultural sector in the Slovak Republic, as well as clarify the recommendations given by various institutions to improve this sector of the economy.

A capoeira angola em Goiânia
Authors: Lima e Silva Renata , Oliveira Lorena Fonte de , Alves Carlos Alberto Martins , Falcão José Luiz Cirqueira 
Published: December 2022

Goiânia, desde a década de 1960, foi palco de uma determinada Capoeira Angola, com o protagonismo pioneiro de Manoel Pio Sales, o Mestre Sabú (1940 – 2017), goiano que se criou em Salvador e que, segundo seus próprios relatos, teve experiências formativas de capoeira, sobretudo com o Mestre Caiçara. No entanto, a partir dos anos 1990, capoeiristas iniciados por Mestre Zumbi aderem à Capoeira Angola e iniciam na referida cidade trabalhos bastante distintos da proposta de Mestre Sabú, dada a aproximação destes com o movimento da Capoeira Angola soteropolitana. A partir da década de 1980, após um longo período de agonia, essa vertente de capoeira passa por um processo de revitalização decorrente de novos esquemas de reorganização política que intensificaram seus discursos identitários. Neste artigo, apresentamos análises acerca da presença da Capoeira Angola na cidade de Goiânia, contextualizando os discursos sobre essa prática e como eles incidem em seu atual momento sócio-histórico.

Abstract: Hyperlipidemia is one of the conditions that constitute metabolic disorder and it is a common public health problem. The condition is characterized by increased levels of cholesterol, triglycerides and/or lipoproteins; it is a recognized as a risk factor for the onset of many diseases such as type 2 diabetes, non-alcoholic fatty liver disease, and cardiovascular disease. Up to now, the primary drugs for treating hyperlipidemia are statins and monoclonal antibody drugs against proprotein convertase subtilisin/kexin type 9 (PCSK9). The main limitation of statins for long-term use is intolerable side effects. Evolocumab and Alirocumab, two monoclonal antibodies against PCSK9, can effectively decrease the level of low-density lipoprotein cholesterol (LDL-C) in patients with statin intolerance and familial hypercholesterolemia, while causing fewer side effects. However, due to its short half-life and high costs, these monoclonal antibody treatments might result in patients’ non-compliance with medication and considerable economic burden on patients. Given that RNA plays a key role in gene regulation, RNA-based therapeutics have become powerful blueprints for designing new anti-hyperlipidemia drugs. Here, we summarized RNA-based therapeutic strategies and the current clinical trials for RNA drugs in hyperlipidemia treatment.

Abstract: Sodium glucose cotransporter 2 inhibitors (SGLT-2i) are a new class of antidiabetic drugs that act by inhibiting the reabsorption of glucose in the proximal renal tubule, which results in lowering the level of blood and urinary glucose. Besides the glucose-lowing effect, some clinical trials found the benefits of SGLT2i in treating heart failure with or without diabetes. In 2021, SGLT2i were recommended by the European Society of Cardiology in treating of heart failure. Compared to heart failure, hypertension is a common cardiovascular disease with an increasing prevalence globally. There is also clinical evidence indicating that SGLT2i can lower blood pressure. Here we focused on addressing the role of SGLT-2i in treating hypertension and its possible mechanism in this review.

Accurate and timely detection and identification of transmission line short circuit faults can considerably improve and simplify their recovery process and hence save the costs associated with the downtime of a power system. Hence, it is essential that a robust and reliable fault diagnosis system completes its operation within an acceptable time window after fault occurrence in the presence of uncertainties and disturbances in the system. The significant costs of mistakenly detected or undetected faults based on the conventional techniques motivate us to present a robust detection and identification system by using the convolutional neural networks. The robustness of this technique is analyzed for the variations of the phase difference between two connected buses, fault resistance, source inductance fluctuations, fault inception angle, local bus voltage fluctuations, and measurement noises. The time delay analysis is also conducted to indicate that the presented technique is able to detect, identify, and estimate the location of faults before tripping relays and circuit breakers disconnect a faulty region.
Review of Integrated Diffractive Deep Neural Networks
Authors: Sheng Huayi 
Published: December 2022

An integrated photonic diffractive deep neural network ( ID^2 NN) is one of the most exciting cross-discipline fields of artificial intelligence and optical computing, combining deep learning with the power of light-speed processing on an integrated platform. We know that neural network in a digital computer is based on transistors, which have significant challenges in keeping pace with Moore's law and limited real-time processing applications due to the increased computational costs associated with them. However, with remarkable progress and advancement in silicon photonic integrated circuits over the last few decades, ID^2 NN hold the promise of on-chip miniaturisation and high-speed performance with low power consumption. This paper covers the essential theoretical background for constructing the ID^2 NN and reviews the research status of optical diffractive neural networks in the field of neuromorphic computing. Problems of narrowing down current ID^2 NN applications are also included in this review. Finally, future research directions for ID^2 NN are discussed, and conclusions are delivered.

Los estudios de relación fuente-demanda dentro del estolón de (Fragaria x ananassa Duch.) son esenciales para configurar sistemas eficientes de producción de plántula en estolones colgantes. Esta investigación analiza, por medio de regresiones, la interrelación de peso seco de raíz y hoja de las plantas madre e hija dentro del corredor. Plantas de fresa ‘Festival’ se plantaron en abril de 2018 en una canaleta elevada a 1.7 m. Después de 239 días, se eligieron al azar 16 plantas con cinco corredores y con al menos cuatro plántulas por corredor. Se determinó el peso seco de raíz, corona y hoja; se realizaron análisis de regresión. Los coeficientes de determinación mostraron un efecto positivo de la raíz de la planta madre sobre el peso de la corona de las plántulas 1, 2, y 3 (R2 > 0.5), pero no de su aparto fotosintético (R2 < 0.07). También, el aparato fotosintético de la plántula tres es importante para el peso de las coronas de todas las plántulas en el corredor (R2 > 0.71). Como conclusión, el enraizamiento de la tercera plántula en el corredor sería importante para incrementar el número de plántulas de buena calidad en un sistema hidropónico de estolones colgantes.
