Published: February 2023

Abstract
Temperature regulation of photovoltaic (PV) modules increases their performance. Among various cooling techniques, phase change materials (PCMs) represent an effective thermal management route, thanks to their large latent heat at constant temperatures. Radiative cooling (RC) is also recently explored as a passive option for PV temperature regulation. In this paper, a heat sink (HS), phase change materials, and radiative cooling are integrated with photovoltaic modules to get low and uniform temperature distribution along the PV module and its improved performance. Eight different combinations are considered for the proposed system, including HS, PCM, and RC and their various combinations. The PCM is selected according to the environmental conditions of a specific location. A comprehensive 2-D model is developed and analyzed in COMSOL-Multiphysics software by solving the governing equations using the finite element method. The performance analysis is carried out for the climatic conditions of the Atacama Desert, having high solar radiation and ambient temperature. The effects of PCM height, ambient temperature, wind velocity, and solar radiation on the performance of the proposed system are studied. The performance of eight different configurations is also compared. The maximum reduction in PV temperature, maximum PV power and a minimum drop in PV conversion efficiency are observed to be 22 K, 152 W and 14% using a combined heat sink and radiative cooling systems, among all other configurations. The findings of this study can be used to select the best PV cooling method among different configurations.

Abstract
Ageing is associated with altered neuroendocrine function. In the context of the hypothalamic supraoptic nucleus, which makes the antidiuretic hormone vasopressin, ageing alters acute responses to hyperosmotic cues, rendering the elderly more susceptible to dehydration. Chronically, vasopressin has been associated with numerous diseases of old age, including type 2 diabetes and metabolic syndrome. Bulk RNAseq transcriptome analysis has been used to catalogue the polyadenylated supraoptic nucleus transcriptomes of adult (3 months) and aged (18 months) rats in basal euhydrated and stimulated dehydrated conditions. Gene ontology and Weighted Correlation Network Analysis revealed that ageing is associated with alterations in the expression of extracellular matrix genes. Interestingly, whilst the transcriptomic response to dehydration is overall blunted in aged animals compared to adults, there is a specific enrichment of differentially expressed genes related to neurodegenerative processes in the aged cohort, suggesting that dehydration itself may provoke degenerative consequences in aged rats.

Abstract
Abstract Touring-polygons problem with obstacles (TPPO) is a very open topic in drone routing problems, wireless sensor networks, robot automation etc. How to efficiently solve TPPO has caused huge attention in both academic and industry. Computationally speaking, touring a set of polygons across obstacles, with which agents need to avoid collision, is NP-hard. In this paper, we propose a discrete scheme that transforms the continuous space into a set of discrete points, which enables us to search the upper bound of optimal solution efficiently. Based on the proposed discrete scheme, a gradient descent algorithm is proposed to solve touringpolygons problem. Second, given a set of polygons and a set of obstacles, we propose a mixedinteger programming model to efficiently find the upper bound. An extensive computational tests demonstrate the efficiency of the proposed methods when comparing the existing methods, i.e., rubber-band algorithm.

Abstract
The aim of this study was to evaluate the effect of Mangifera indica leaf hay on the control of Haemonchus contortus in lambs, Sixteen crossbred Santa Inês x Dorper lambs were divided into two homogeneous groups. One group was provisioned with 5g of leaf hay /Kg of body weight (BW) and other was not with the hay of this plant.On the 21st day, the animals of both groups were inoculated with infective larvae from H. contortus. The growth, intake and performance for animals were evaluated before and after the nematode infection. Lamb blood parameters were analyzed before the hay administration (day − 14), when the animals receiving the hay and were not-infected (day 7) and when receiving the hay and were infected with H. contortus (day 30). The faeces were collected on day 42, 44, 46, and 48 of the experiment to quantify the eggs per gram of faeces (EPG). The body weight gain was lower when the animals were infected to both groups. In the second period, the animals fed with the hay of M. indica showed higher feed efficiency than the un-treated group. The eosinophil concentrations were higher in the last two periods evaluated. However, the EPG averages were similar between lamb groups. Thus, the inclusion of hay from M. indica leaves in the lamb feed can lead to an improvement in feed efficiency of the animals infected with H. contortus. It can also increase their eosinophil concentration, which in turn could improve tolerance to the nematode infection.

Abstract
Tomonaga-Luttinger liquid (TLL) behavior in one-dimensional systems has been predicted and shown to occur at semiconductor-to-metal transitions within two-dimensional materials. Reports of mirror twin boundaries (MTBs) hosting a Fermi liquid or a TLL have suggested a dependence on the underlying substrate, however, unveiling the physical details of electronic contributions from the substrate require cross-correlative investigation. Here, we study TLL formation in MTBs within defectively engineered WS2 atop graphene, where band structure and the atomic environment is visualized with nano angleresolved photoelectron spectroscopy, scanning tunneling microscopy and scanning tunneling spectroscopy, and non-contact atomic force microscopy. Correlations between the local density of states and electronic band dispersion elucidated the electron transfer from graphene into a TLL hosted by MTB defects. We find that MTB defects can be substantially charged at a local level, which drives a band gap shift by ∼0.5 eV.

Abstract

Background
In Uganda, brucellosis remains an endemic public health concern that requires adequate knowledge among the public and medical practitioners to reduce risk of transmission, correctly diagnose and manage infected humans. This study investigated the seroprevalence of human brucellosis, assessed knowledge of patients and medical practitioners about human brucellosis, and evaluated factors that influence good self-reported practices of medical practitioners towards the disease.
Methods
A cross-sectional study was conducted using a questionnaire and key informant guide among 300 patients and 30 medical practitioners respectively from May to July 2019 at Zia Angelina Health Centre, Wakiso district. Serum samples were tested for Brucella antibodies using Rose Bengal Plate Test. Cross tabulation between the five categories of professionals (nurses, laboratory personnel, medical doctors, clinicians, and pharmacists) and their responses to knowledge and practices was performed using Chi-square test. Logistic regression analysis was performed to measure the strength of association between overall knowledge and practice scores and demographic characteristics of study participants using odds ratios at 95% confidence intervals. Variables with p-value < 0.05 were considered as predictors of outcome.
Results
Human brucellosis seroprevalence was 0.3% (n = 1, CI: 0.0-2.4). Only 6.3% (n = 19, CI: 4.1–9.7) of patients were knowledgeable about human brucellosis, and having secondary education [AOR = 0.06, 95% CI: 0.01–0.47, p = 0.007] was significantly associated with good knowledge. Overall, 26.7%, (n = 8, p = 0.414) of medical practitioners were considered to have good knowledge of human brucellosis, however, no predictor to good knowledge was found. About a third (33.3%, n = 10, p = 0.047) of respondents had an overall good self-reported practice score towards human brucellosis. Being at a certificate education level [AOR = 0.04, 95% CI: 0.00-0.78, p = 0.033], and level of knowledge about brucellosis [AOR = 0.03, 95% CI: 0.00-0.59, p = 0.020] were identified as predictors of good practices.
Conclusions
The prevalence of human brucellosis was very low among patients who participated in the study, with participants having poor overall knowledge and practices towards the disease. These findings suggest a need for sensitization programs to improve human brucellosis awareness, and to enhance management of the disease in the health facilities.

Abstract
Background
To determine the impact of a longitudinal, near-peer, dedicated ECG didactic curriculum on internal medicine resident ability to accurately interpret ECGs.
Methods
This study employs a prospective cohort design. Internal medicine residents at University at Buffalo participated in monthly ECG didactic sessions over a 7-month period. Residents were invited to complete pre- and post-curriculum questionnaires. Responses were anonymous and participation voluntary. Data collected included basic demographics, career interest, exposure to clinical cardiology, and number of sessions attended. Residents were asked to interpret sixteen unique ECGs, divided evenly among eight common rhythms into both questionnaires. Pre- and post-curriculum cohorts were compared using t-tests and chi-square analyses. Associations between attendance, comfort level in interpretation, and number of correct interpretations were analyzed using Pearson correlations. Multivariate linear regression determined the strongest predictor of the number of correct ECG interpretations.
Results
The post-curriculum cohort correctly interpreted a significantly greater percentage of ECGs compared to pre-curriculum cohort (74.5% vs. 60.9%, p < 0.001). Didactic attendance was significantly associated with comfort level in interpreting ECGs (r = .328, p = .018) and trended towards an increased number of correct interpretations (r = .248, p = .077). Residents who attended three or more sessions demonstrated increased ECG interpretation skills compared to those who attended two or fewer sessions (80.0% vs. 71.1%, p = 0.048). Number of clinical cardiology rotations attended was significantly associated with correct interpretations (r = .310, p < .001) and was the strongest predictor of accurately interpreting ECGs (β = 0.29, p = .037).
Conclusions
Participation in a longitudinal, near-peer ECG didactic curriculum improved resident ability to interpret ECGs. A curriculum which contains both didactic sessions and clinical exposure may offer the greatest benefit in improving ECG interpretation skills.

Abstract
Background: The prevalence of food allergy (FA) has been increasing steadily over the past 2 decades to 3 decades, with diversified symptoms and increasing severity. The long-term outcome will affect the growth and development of children, and it may be associated with inflammatory bowel disease. However, its pathogenesis remains unclear. Previous studies have shown that early infancy is a crucial time when gut microbiota has an impact on the development of food allergy. However, there is no unified perspective on the characteristics on dysbiosis in early life link between dysbiosis and the future of allergic diseases.
Objective: We investigated the association between composition in gut microbiota in early life and long-term clinical manifestations in children with food allergy.
Methods: In this study, 16S rDNA gene high-through sequencing method was used to analyze the composition of gut microbiota in children with food allergy in early life in southern Zhejiang, and the clinical manifestations were followed up for 2 years to analyze the influence of gut microbiota changes in early life on the later clinical manifestations.
Results: we found that the diversity of gut microbiota in children with food allergy did not change, but the abundance of microbiota changed. The bacterial markers of food allergy may be Akkermansia, Parabacteroides, Blautia and Escherichia-Shigella, the lack of gut microbiota many be Bifidobacteriumand Clostridium. After two years，two of the ten children with food allergy still had symptoms of food allergy, the intestinal flora of these two cases in early childhood showed an increase in Escherichia-Shigella and a decrease in Bifidobacterium, The other eight cases had remission of allergic symptoms.
Conclusion: We concluded that food allergy is not associated with intestinal flora diversity. Most of the symptoms of food allergy can be relieved by the age of 3 years old, which is related to the composition of early intestinal flora. Escherichia-Shigellaand Bifidobacterium may affect the prognosis of food allergy.

Abstract
The research aimed at analyzing several facets of innovation management in the field of fruit and vegetable preservation. The analysis was based on a review of the trends using the Web of Science database and a questionnaire survey to assess the potential influence of the COVID-19 pandemic on the condition of innovation management in the field of fruits and vegetables preservation. A thorough analysis and evaluation of 256 journal articles retrieved from the Web of Science database were done. The results show that there has been an imbalance in the distribution of researchers by region and that research on fruit and vegetable preservation innovations did not increase until recent years. A total of 18.04% of the papers on the subject that the investigation could locate were generated by Italy and the USA, accounting for around 9.02% of them each. Furthermore, the results showed that, in terms of the demand for innovations and investment level in fruit and vegetable preservation, the COVID-19 innovation disruption had a bigger influence on large-scale firms than on small businesses. It is also worth pointing out that the research findings to now, which have primarily been based on laboratory-scale studies, have not fully taken into account the cost-effectiveness of the suggested preservation technologies. The goal of a cost-effective therapy can only be partially met by the different approaches that have been proposed. If sustainable innovation management in the field of fruits and vegetables preservation is to be achievable on a global scale, an effort must be made to fund more research activities, particularly in the cold and arid and semi-arid regions. Practical considerations dictate that small-scale research that uses readily available and affordable materials be encouraged. This will make it possible to do a logical cost-benefit analysis of a particular technique or strategy for addressing fruit and vegetable preservation.

Published: February 2023

Abstract
The local prediction of fatigue damage within polycrystals in a high-cycle fatigue setting is a long-lasting and challenging task. It requires identifying grains tending to accumulate plastic deformation under cyclic loading. We address this task by transcribing ferritic steel microtexture and damage maps from experiments into a microstructure graph. Here, grains constitute graph nodes connected by edges whenever grains share a common boundary. Fatigue loading causes some grains to develop slip markings, which can evolve into microcracks and lead to failure. This data set enables applying graph neural network variants on the task of binary grain-wise damage classification. The objective is to identify suitable data representations and models with an appropriate inductive bias to learn the underlying damage formation causes. Here, graph convolutional networks yielded the best performance with a balanced accuracy of 0.71 and an F1-score of 0.34, outperforming phenomenological crystal plasticity (+68%) and conventional machine learning (+17%) models by large margins. Further, we present an interpretability analysis that highlights the grains along with features that are considered important by the graph model for the prediction of fatigue damage initiation, thus demonstrating the potential of such techniques to reveal underlying mechanisms and microstructural driving forces in critical grain ensembles.

Abstract
Urea detection and elimination attracted great attention as a kind of representative toxin with the highest daily molar production for dialysis patients. Low molecular weight, high solubility, and low reactivity make it a challenge to absorb urea. Although there are different ways to for urea removal, there are some problems like causing side effects, being time-consuming, and wasting high amounts of absorbents. In the present research, urea adsorbents were prepared by synthesizing magnetic nanoparticles (Fe3O4 NPs) by co-precipitation method, functionalizing with SiO2 (Fe3O4@SiO2), and then modifying by surface imprinting poly (methyl methacrylate) with urea (MMIPs). The Fe3O4 and Fe3O4@SiO2 NPs were nearly spherical (5-20 nm in diameter) and in size. In 10 minutes, the MMIPs could absorb 50% of dialysate. The urea binding capacity of the system at the NP: Urea ratio of 0.5 and initial urea concentrations of 100 mg dL-1 were calculated at 1.06 mmol g-1. Under the control of a pseudo-first-order equation, the adsorption process was determined. The Freundlich isotherm model was fitted to the equilibrium adsorption data. These MMIPs are proposed as promising tools for urea removal in hemodialysis to reduce dialysis time and improve patient compliance with the therapy and also for dialysate regeneration.
