Authors: Pham H. M. , Pham K. H. 
Published: April 2023

Abstract

Biosecurity measures are critical for protecting pig health; however, medium- and small-scale farmers in Vietnam do not always use these practices. This study performed a cross-sectional investigation of Porcine Reproductive and Respiratory Syndrome virus (PRRSV) seroprevalence in healthy pigs without PRRSV vaccination from four provinces in Vietnam from 2015 to 2017 and analyzed risk factors associated with PRRSV serological status at herd levels. A total of 1202 serum samples from 564 pig households were collected. True PRRSV seroprevalence at the animal and herd levels was 19.91% (95% CI: 17.54–22.50) and 20.59% (95% CI: 17.17–24.48), respectively. Pig farms, which used local feed grains and kitchen waste (OR = 2.18; P = 0.002), introduced newly purchased pigs without isolation (OR = 2.12; P = 0.007), or purchased pigs from local wholesale markets (OR = 3.48; P = 0.000), were associated with a higher risk of PRRSV seroprevalence. Those risk factors had positive interaction effects on the prevalence of PRRSV antibodies at herd levels (P = 0.000). The information on the evidence of PRRSV seroprevalence and risk factors is a valuable resource to improve awareness of the potential PRRSV transmission for farmers and veterinary services. Biosecurity education for pig owners and surveillance strategies on healthy pig populations will help significantly reduce the health risks of pig farms, especially small and medium pig farms, and minimize the economic effects of PRRS as well as other infectious diseases.

Abstract
Strong seedling vigor is an important breeding target for rice varieties used in direct seeding. Shoot length (SL) is one of the important traits associated with seedling vigor characterized by rapid growth of seedling, which enhance seedling emergence. Therefore, mining genes for SL and conducting molecular breeding help to develop varieties for direct seeding. However, few QTLs for SL have been fine mapped or cloned so far. In this study, a genome-wide association study of SL was performed in a diverse rice collection consisting of 391 accessions in two years, using phenotypes generated by different cultivation methods according to the production practice, and a total of twenty-four QTLs for SL were identified. Among them, the novel QTL qSL-1f on chromosome 1 could be stably detected across all three cultivation methods in the whole population and indica subpopulation. Through gene-based haplotype analysis of the annotated genes within the putative region of qSL-1f, and validated by gene expression and knockout transgenic experiments, LOC_Os01g68500 was identified as the causal gene for SL, which has a single-base variation (C-to-A transversion) in its CDS region, resulting in the significant difference in SL of rice. LOC_Os01g68500 encodes a DUF538 (Domain of unknown function) containing protein, and the function of DUF538 protein gene on rice seedling growth is firstly reported in this study. These results provide a new clue for exploring the molecular mechanism regulating SL, and promising gene source for the molecular breeding in rice.
Duplicated FAD2 genes, fatty acid profiles and membrane integrity in cold stress response of durum wheat genotypes
Authors: Cuppari Selva Yanet , Carrera Alicia Delia , Diaz Marina Lucia 
Published: April 2023

Abstract
Fatty acid desaturases (FADs) introduce double bonds at specific positions of fatty acyl chains and are involved in the protection of membrane integrity at low temperatures. Three genotypes of Triticum turgidum ssp. durum with differences in cold tolerance were considered. The analysis of TdFAD2 sequences identified an intronless gene encoding a 387 amino acid protein including three histidine domains. The in silico mapping on the cv Svevo genome revealed the occurrence of four FAD2 copies in tandem localized in 6A and 6B chromosomes and suggested an inversion in 6B. Three out of eight copies consisted of non-functional sequences. The exploration of the 5´regulatory region showed differences in TF binding sites among the copies suggesting certain specificity in gene expression. The evaluation of FAD2 by qRT-PCR, in plants exposed at 4 ˚C, showed transcriptional induction and variations among the genotypes. The fatty acid profiles determined by gas chromatography revealed that the major component of the fatty acids (60–80%) was linolenic acid (18:3). The more cold-tolerant genotypes increased 18:1 and 18:2 (the product of FAD2) content whereas the sensitive genotype did not show marked variations. Membrane integrity evaluated through electrolyte leakage was in accordance with phenotypic differences in cold tolerance. Our work provides information about the structure of TdFAD2 locus and the FAD2 expression and fatty acid profiles under the cold effect. Molecular and biochemical characterization of germplasm contributes to explain phenotypic variability in complex traits and thus facilitates the development of new varieties adapted to specific cultivation areas.
Evaluation of the mechanisms acting on the Atlantic Meridional Overturning Circulation in CESM2 for the 1pctCO2 experiment

Published: April 2023

Abstract

The Atlantic Meridional Overturning Circulation (AMOC) is a crucial component of the Earth’s climate system due to its fundamental role in the uptake and distribution of important tracers such as heat, carbon, and oxygen. Evaluating changes in AMOC in a warming climate is paramount to understanding the potential influence on global climate. In this study, we utilized outputs produced by the Community Earth System Model for Phase 6 of the Coupled Model Intercomparison Project, in addition to in situ data, to investigate changes in AMOC and the associated physical processes. Two experiments were carried out: a control experiment and an experiment with an annual increase of 1% CO2. Our analysis revealed a significant decrease in AMOC, with the upper branch weakening more than 60% and shallowing more than 600 m, compared to in situ data, leading to a reduction in heat transport to high latitudes in the North Atlantic. This decline was associated with changes in mixed layer depth and buoyancy in high latitudes of the North Atlantic, resulting in the shutdown of deep convection and potentially affecting the formation of North Atlantic Deep Water and Antarctic Bottom Water. Furthermore, the increase in CO2 levels altered the pattern of several parameters and the way they determine the flow of freshwater to the North Atlantic Ocean. Our findings suggest that continued warming may further weaken AMOC, with significant implications for global climate.

Abstract
The Internet of Things (IoT) makes it possible to collect data from, and issue commands to, devices via the internet, eliminating the need for humans in the process while increasing productivity, accuracy, and economic value. Therefore, the integration of IoT plays a crucial role in achieving high efficiency and sustainability in the production of renewable energy that could be used to meet future electricity needs. While this approach has many significant benefits, it also opens smart renewable energy to cyber-attacks, giving hackers a new window of opportunity to take advantage of renewable energy’s vulnerabilities. This obviously affects the financial and physical functioning of smart renewable energy. This article reviews the literature on cybersecurity threats and vulnerabilities in IoT-based smart renewable energy and cyber-attacks on power systems. False data injection, replay, denial of service (DoS), and brute force credential attacks have been identified as the main threats to IoT based smart renewable energy. These threats exploit IoT based smart renewable energy’s vulnerabilities such as the usage of insecure communication protocols, poor encryption techniques, poor hash algorithms, lack of access control, lack of parameter sanitization, and the inappropriate use of authentication alongside encryption. The findings of this review will assist researchers in better understanding the issues surrounding the cybersecurity of IoT-based smart renewable energy and the needs for grid security in light of the exponential growth in the number of renewable energy sources connected to the grid.

Published: April 2023

Abstract
Our objective is to study the anatomy and biometry of the radial artery in 45 anatomical subjects, 90 forearms dissected in the anatomy laboratory of our university, and to report the implications of this study in daily practice in Cardiac Surgery.
Our results showed that the distance between the epicondyle and the emergence of the radial artery was 32.4 ± 6.67 mm in men and 30.7 ± 9.00 mm in women, with a mean of 31.8 ± 7.58 mm. In the right upper extremity, the mean diameter of the radial artery was 31.5 ± 5.62 mm in its proximal part. In men, the mean diameter of the radial artery was 30.7 ± 4.45 mm in its proximal part and 24.4 ± 7.62 mm in its distal part. The mean diameter of the radial artery in the left upper extremity was 31.6 ± 5.94 mm proximally and 26.4 ± 6.79 mm distally. In men, the mean diameter of the left radial artery was 30.7 ± 4.45 mm proximally and 25.1 ± 5.69 mm distally. The mean length of the left radial artery was 197.0 ± 16.87 mm. The mean length of the right radial artery was 201.2 ± 33.36 mm. The results showed the presence of radial artery variation in 1.11% of the 90 dissected upper extremities.
If it is therefore important that the technique of radial artery harvesting is safe and reliable for its use as a graft, we affirm that it is also important to be aware of the possible variations of this artery despite their rarity.
zk-Oracle: Trusted Off-Chain Compute and Storage for Decentralized Applications
Authors: Gu Binbin , Nawab Faisal 
Published: April 2023

Abstract

Blockchain and Decentralized Applications (DApps) are increasingly important for creating trust and transparency in data storage and computation. However, on-chain transactions are often costly and slow. To overcome this challenge, off-chain nodes can be used to store and compute data. Unfortunately, this introduces the risk of untrusted nodes. To address this, authenticated data structures have been proposed , however, this ignores the compute of data from the raw data. We tackle this challenge by introducing zk-Oracle, which provides an efficient and trusted compute and storage off-chain. There is a challenge in using zero-knowledge proofs (zk-proof for short), which is the large proof generation time. We aim to overcome it with novel designs in zk-Oracle. zk-Oracle builds on zk-proofs technologies to achieve two goals. First, the computation of data structures from raw data and the corresponding proof generation is improved in terms of performance. Second, the verification on-chain is inexpensive and fast. Our experiments show that we can speed up zk-proof generation by up to more than 550× faster than the baseline method.

Risk perception and ride-pooling choice intention: a moderated mediating effect model
Authors: Miao Ge , Yuan Pengcheng 
Published: April 2023

Abstract
In order to explore the mechanism of urban residents ' risk perception on ride-pooling intention under the background of public health crisis, based on the moderated mediation effect model, this paper explores the relationship between residents ' risk perception, ride-pooling attitude and ride-pooling intention through correlation analysis and mediation effect analysis, and uses bootstrap test to analyze the moderating effect of gender and residence risk level. The results show that: (1) There is a significant negative correlation between risk perception and the two dimensions of ride-pooling attitude and intention; there is a significant positive correlation between ride-pooling attitude and ride-pooling intention. (2) The attitude of ride-pooling plays a complete mediating role between risk perception and ride-pooling intention. (3) The direct predictive effect of risk perception on ride-pooling intention and the mediating effect of ride-pooling attitude will not be regulated by gender. The direct predictive effect of risk perception on ride-pooling intention will be regulated by the risk level of residence. Based on the above research results, some suggestions on epidemic prevention measures and platform management are put forward to provide reference for urban governance and ride-pool optimization.

Published: April 2023

Abstract

Microbial pollution in marine environments is one of the critical issues with regard to the sanitary status of recreational activities and seafood harvesting due to a potential contamination by pathogenic microorganisms. This review's objectives were to identify instances of bacterial, viral and protozoan parasite pollution in the Tunisian coastal region and to make recommendations for further research. Fecal indicators such as Escherichia coli and Salmonella spp. were detected in samples of clams and mussels. Vibrionaceae species were also recorded in seawater, sediment, fish and clams in different sites from north to south with the dominance of Vibrio alginolyticus. Bivalve mollusks collected from the Tunisian coast have been revealed to harbor viruses as well as protozoan parasites. Furthermore, the isolation of multidrug-resistant bacterial strains from Tunisian coastlines proves the significant spread and circulation of antibiotic resistance caused by the massive use of antibiotics. In conclusion, we suggest intensive monitoring and cutting-edge wastewater treatment technologies to enhance seawater quality and preserve the biodiversity of aquatic life. Rapid detection techniques for the most important pathogenic microorganisms in seafood and seawater must be also developed to reduce human health risk.

Authors: Oishi Arifa Hossain , Anjum Md Tanveer , Islam Md Muhsiul , Nayan Md Faysal 
Published: April 2023

Perovskite solar cells (PSCs) have a high-power conversion efficiency that exceeds 20%, distinguishing them from other new photovoltaic technologies. The Solar Cell Capacitance Simulator (SCAPS-1D) was used in this study to investigate the effects of absorber layer properties on photovoltaic solar cell performance. SCAPS simulation software employs a numerical simulation technique to fully comprehend the principles of solar cell operation and predict the best power conversion efficiency. A three-layer solar cell model comprised of an Electron Transport Layer (ETL), a Hole Transport Layer (HTL), and a Perovskite Absorber Layer was used in this study. The variations in Voc, Jsc, FF, and PCE were investigated by varying the thickness of the absorber layer. The purpose of this research is to find the absorber layer thickness that produces the highest efficiency for two different ETM layer ZnO and SnO2. This simulation model can significantly aid in the fabrication of high-efficiency ZnO and SnO2 based PSCs.

Authors: Dąbrowska Karolina , Zaczek Zuzanna , Majewska Krystyna , Sobocki Jacek 
Published: April 2023

Abstract
Total parenteral nutrition (TPN) is a life-saving nutritional therapy in conditions where enteral nutrition is contraindicated or inadequate. However, it has been associated with side effects, one of which is parenteral nutrition–associated liver damage (PNALD). The main features of PNALD are cholestasis, fatty liver disease, and early fibrosis, followed by disease progression, cirrhosis, and liver failure. Risk factors for parenterally fed patients include short bowel syndrome, bacterial overgrowth and translocation, disturbances in hepatobiliary circulation and lack of enteral nutrition, and the choice of an inappropriate fat mixture. The source of the oil present in lipid emulsions is believed to play an important role in the development of long-term complications.
This review analyzes the current literature and research on the pathogenesis of PNALD. Likewise, possible options for preventing this complication were discussed.

Published: April 2023

Abstract
This article focuses on the exact periodic solutions of nonlinear wave equations using the well-known Jacobi elliptic function expansion method. This method is more general than the hyperbolic tangent function expansion method. The periodic solutions are found using this method which contains both solitary wave and shock wave solutions. In this paper, the new results are computed using the closed-form solution including solitary or shock wave solutions which are obtained using Jacobi elliptic function method. The corresponding solitary or shock wave solutions are compared with the actual results. The results are visualised and the periodic behaviour of the solution is described in detail. The shock waves are found to break with time, whereas, solitary waves are found to be improved continuously with time.
