Remote Virtual Simulation for Incident Commanders—Cognitive Aspects

Due to the COVID-19 restrictions, on-site Incident Commander (IC) practical training and examinations in Sweden were canceled as of March 2020. The graduation of one IC class was, however, conducted through Remote Virtual Simulation (RVS), the first such examination to our current knowledge. This paper presents the necessary enablers for setting up RVS and its influence on cognitive aspects of assessing practical competences. Data were gathered through observations, questionnaires, and interviews from students and instructors, using action-case research methodology. The results show the potential of RVS for supporting higher cognitive processes, such as recognition, comprehension, problem solving, decision making, and allowed students to demonstrate whether they had achieved the required learning objectives. Other reported benefits were the value of not gathering people (imposed by the pandemic), experiencing new, challenging incident scenarios, increased motivation for applying RVS based training both for students and instructors, and reduced traveling (corresponding to 15,400 km for a class). While further research is needed for defining how to integrate RVS in practical training and assessment for IC education and for increased generalizability, this research pinpoints current benefits and limitations, in relation to the cognitive aspects and in comparison, to previous examination formats.
FORMALITY OF CYCLIC CHAINS

We prove a conjecture raised by Tsygan [12], namely the existence of an L∞-quasiisomorphism of L∞-modules between the cyclic chain complex of smooth functions on a manifold and the differential forms on that manifold. Concretely, we prove that the obvious u-linear extension of Shoikhet’s morphism of Hochschild chains solves Tsygan’s conjecture.
COVID-19 outbreak in Brazil: Adherence to national preventive measures and impact on people’s lives

Background: The first case of COVID-19 infection was diagnosed in Brazil 26th February 2020. By March 16th, physical distancing and confinement measures were implemented by the Brazilian government. Little is known about how these measures were followed up by the Brazilian people and their impact on daily routine.Methods: In early April 2020, using an online platform, we organized an online survey among adults living in Brazil about their COVID-19 preventive behavior. Results: Data from 23.896 respondents were analyzed (mean age: 47.4 years). Due to COVID-19 restrictions, half (51.1%) of the professionals reported working from home. Regular handwashing was practiced by 98.7% of participants; 92.6% reported adhering to the 1.5-2m physical distancing rule, but only 45.5% wore a face mask when going outside. While 29.3% of respondents found it relatively easy to stay at home, indoor confinement was extremely difficult for 7.9% of participants. Moreover, 11% of participants were extremely worried about their health during the COVID-19 epidemic.Younger people, male, persons living in a rural area/village or popular neighbourhoods, students and workers reported less preventive behaviour. Conclusion: Restrictive measures markedly affected the daily and professional routines of Brazilians. Participants showed a satisfactory level of adherence to national COVID-19 prevention guidelines. Qualitative and follow-up studies are needed to monitor the impact of COVID-19 in the Brazilian society.
Illegal Fishing: In the Eyes of Filipino Fishermen

Fishing is among the oldest method of living, wherein the people living in the coastal areas depend on the abundance of aquatic resources. Until today, millions of people rely on marine fisheries for food and livelihood. Unfortunately, many fishermen engaged in a fast and more profitable way of fishing through illegal methods because of the high demand. Illegal fishing has different methods, but it has a devastating effect on the depletion of fish stock (Afoakwah, Osei, & Effah, 2018; Gillam & Charles, 2018; Hilborn, 2011).

Title page Title: PTX3 activates classic complement pathway and mediates phagocytosis of cholesterol-induced apoptotic macrophages in atherosclerosis Running Title: PTX3 activates classic complement pathway

Backgrounds/Aims: Apoptotic macrophages are removed by neighboring phagocytes (efferocytosis), which is an important event in advanced atherosclerosis. We reported the long pentraxin 3 (PTX3) located at the membrane of late apoptotic macrophages, mediates efferocytosis in a cell model of advanced atherosclerosis. However, the mechanism underlying PTX3-mediated apoptotic cell clearance in atherogenesis is unclear. Methods: We modeled macrophage apoptosis in advanced plaques by incubating macrophages (peritoneal macrophages isolated from C57 mice) with free cholesterol (free cholesterol-induced apoptotic macrophages, FC-AMs). FC-AMs were added to a monolayer of fresh phagocytes°Cmacrophages°C to study the engulfment response. The percentage of phagocytes that ingested FC-AMs was quantified by using confocal microscopy. C1q and C3b were detected by using fluorescence-activated cell sorter (FACS) and the confocal microscopy. Results: We found that PTX3 significantly enhances complement C1q binding on FC-AMs and was correlated with improved activating of classic complement pathway. C3b was the
The relationship between key natural and social factors and the transmission of novel coronavirus disease 2019 in China

Background Novel coronavirus disease 2019 (COVID-19) has become a global pandemic. This study aims to explore the relationship between key natural and social factors and the transmission of COVID-19 in China. Methods This study collected the number of confirmed cases of COVID-19 in 21 provinces and cities in China as of February 28, 2020. Three provinces were included in the sample: Hainan, Guizhou, and Qinghai. The 18 cities included Shanghai, Tianjin and so on. Key natural factors comprised monthly average temperatures in the January and February 2020 and spatial location as determined by longitude and latitude. Social factors were population density, Gross Domestic Product (GDP), number of medical institutions and health practitioners; as well as the per capita values for GDP, medical institutions, and health practitioners. Excel was used to collate the data and draw the temporal and spatial distribution map of the prevalence rate (PR) and the proportion of local infection (PLI). The influencing factors were analyzed by SPSS 21.0 statistical software, and the relationship between the dependent and independent variables was simulated by 11 models. Finally, we choose the exponential model according to the value of R2 and the applicability of the model. Results The temporal and spatial distribution of the PR varies across the 21 provinces and cities identified. The PR generally decreases with distance from Hubei, except in the case of Shenzhen City, where the converse is observed. The results of the exponential model simulation show that the monthly minimum, median, and maximum average temperatures in January and February, and the latitude and population density are significant and thus will affect the PLI. The corresponding values of R2 are 0.297, 0.322, 0.349, 0.290, 0.314, 0.339, 0.344, and 0.301. The effects of other factors were not statistically significant. Conclusions Among the selected key natural and social factors, higher temperatures may decrease the transmission of COVID-19. From this analysis, it is evident that if the temperature decreases by 1℃, the average PLI increases by 0.01. Further, it was established that locations at more northern latitudes had a higher PLI, and population density showed an inverse relationship with PLI.
Associations of Serum Lipids and Lipoproteins with the Estimated Glomerular Filtration Rate in the Adult Chinese Population: A Cross-sectional Study

Background: Dyslipidemia has a critical impact on renal dysfunction, but the exact types of lipids and lipoproteins that influence the estimated glomerular filtration rate (eGFR) are under investigation. Observations from an adult Chinese population ≥20 years old are lacking. The present study is to investigate the associations of total cholesterol (TC), triglycerides (TG), high-density lipoprotein-cholesterol (HDL-C), and low-density lipoprotein-cholesterol (LDL-C) with eGFR, and the risks for a mildly and a moderately/severely reduced eGFR. Methods: A total of 16,206 participants from a national representative adult population (20 years of age or older) in China were included. All calculations were weighted based on the Chinese population data and the sampling scheme. Results: Upon stratifying the population based on lipids or lipoprotein categories, we observed a significantly lower mean eGFR as well as a higher estimated prevalence of impaired eGFR among Chinese adults with TG levels in the ranges of 1.7 mmol/L≤ TG <2.3 mmol/L [mean eGFR: 110.99 mL/min per 1.73 m 2 , P =0.0000; prevalence of mildly eGFR impairment: 30.92%, P =0.0000; prevalence of moderately/severely eGFR impairment: 2.01%, P =0.1842] and ≥2.3 mmol/L [111.62 mL/min per 1.73 m 2 , P =0.0000; 27.92%, P =0.0000; 2.81%, P =0.0174], compared to those among individuals with normal TG [122.03 mL/min per 1.73 m 2 ; 19.96%; 1.20%]. Also, a higher prevalence of mildly impaired eGFR was observed with 3.4 mmol/L≤ LDL-C <4.1 mmol/L (27.93%) compared with LDL-C <3.4 mmol/L (22.61%, P =0.0092). An elevated TG was proven to be an independent risk factor for decreased eGFR [β(SE) -0.0238(0.0039), P =0.0000], and each per mmol/L increase in TG was associated with the 1.19-fold and 1.31-fold increased risks for mildly impaired eGFR and moderately/severely impaired eGFR, respectively ( P =0.0000, 0.0001). A decreased HDL-C also showed a negative contribution to eGFR [-0.0883(0.0176), P =0.0000]. In contrast, increased TC was associated with increased eGFR [0.0314(0.0060), P =0.0000] and a reduction in the risk for mildly impaired eGFR by 0.91-fold ( P =0.0302). Increased LDL-C also contributed to an elevated eGFR [0.0251(0.0070), P =0.0004]. Conclusion: A decreased eGFR could be attributed independently to an elevated TG or reduced HDL-C. It emphasizes the importance of effective control of TG and HDL-C for preserving eGFR.
Skin-Gut Axis in Psoriasis Setting and Plan for Action: The Effect of Probiotics Supplementation On Clinical Outcomes, Metabolic Endotoxemia, Inflammation, and Cardiovascular Risk in Patients with Psoriasis

Objective: Studies have proposed a link between psoriasis and an imbalanced gut microbiome. Therefore, the modulation of the gut microbiota with probiotics may improve clinical outcomes, metabolic endotoxemia, chronic inflammation, and cardiovascular risk factors in patients with psoriasis.Methods: Forty-six patients with psoriasis randomized into two groups, group 1 received a twice a day capsule having freeze-dried powder with 1.6×109 CFU for eight weeks, and group 2 received placebo. For clinical outcomes, we used the Psoriasis Area and Severity Index (PASI), blood pressure, and SF36 to measure the quality of life. And for biochemistry analysis, we measured pro-inflammatory cytokines (hs-CRP and IL1-β), lipopolysaccharides (LPS), and lipid profile. All the data collected at baseline and the end of the study. Results: Forty-six patients (28 [60%] female; mean [SD] age, 42.51 [14.55] years) contributed to the study. Improvements in SF36 score as an indexed for the QOL was significant in patients taking probiotics supplementation comparing to the placebo group and PASI (-5.06±2.10 vs. 0.30±1.80, P=0.049) as well. After the intervention, the treatment group had significant reductions in LDL and TC compared to the placebo group. In addition, we observed a considerable reduction in serum LPS levels (-7.21±10.33 vs. -2.74±0.97 mmol/L, P=0.010), hs-CRP levels (-1.67 ±0.95 vs. -0.70+ 0.38 mg/L, P=0.013), and IL1- β levels (-1.64 ±1.10 vs. 0.17+ -0.20 mg/L, P=0.043) in the probiotics group. Conclusion: This study shows that probiotics significantly improved the quality of life and seriousness in psoriatic patients. Moreover, it enhances cardiovascular risk factors and inflammatory/oxidative stress markers. Trial registration: This trial also was recorded in the Iranian registry of clinical trials (https://www.irct.ir) (code: IRCT20191124045483N1).
Determination of Caffeine in Some Sudanese Beverages by High Performance Liquid Chromatography

Simple High Performance Liquid Chromatographic (HPLC) method was validated for determination of the content levels caffeine in 15 different beverage samples commercially available in Sudan local markets. Shim-pack VP-ODS column was used with methanol: water (30:70)% (v/v) eluent. The detector wavelength was set at 270 nm. Linearity of the method was check from 10-100 ppm and the correlation coefficient was 0.9999. The method detection limit was 0.023 ppm and the precision was 1.25% at 40 ppm caffeine concentration. the spiked recoveries for caffeine were 99%, 105%, 99.2%, 102% and 102% in Pepsi Cola, Coca Cola, Red Bull, Gazaltain black tea and Coffee samples respectively. The caffeine contents in tea samples ranged from 440 ppm to 473 ppm with average concentration of 458.6 ppm. The caffeine concentrations in energy drinks samples ranged from 170.6 ppm to 324 ppm with average concentration of 255.6 ppm. The coffee sample contains 252.4 ppm. The carbonated soft drinks showed caffeine content in the range of 32.4 ppm to 133.3 ppm with average concentration of 96 ppm. In addition, the concentrations of caffeine have been converted into the daily intake doses based on beverages consumption. The mean values of caffeine daily intakes were 183 mg, 101 mg, 64 mg and 38 mg through the ingestion of tea, coffee, energy drinks and soft drinks, respectively.
Regulation of Ethylene Biosynthesis in Broccoli Flower Buds in Controlled Atmospheres

The effect of controlled atmospheres on the regulation of ethylene biosynthesis during the senescence of broccoli flower buds (Brassica oleracea, L. Italica group cv. Green Valiant) was assessed. The broccoli buds wee stored in the dark at 25C under a continuous stream of nitrogen containing the following percentages of CO2-O2 : 0-20 (air), 0-2.5, 6-20, and 10-20. Generally, respiration, ethylene production, and ethylene-forming enzyme (EFE) activity followed a climacteric like pattern in all atmospheres. The ACC content changed little during the “climacteric”, but increased dramatically during the “post-climacteric” period, when ethylene production and EFE activity decreased. Under high CO2, respiration was reduced, but ethylene production and EFE activity were temporarily stimulated early during treatment. Under low O2, respiration, ethylene production, EFE activity, and ACC content were reduced, and the “climacteric” and chlorophyll losses were delayed to a greater extent than under high CO2. Whatever the treatment, ACC level was not the limiting factor in ethylene biosynthesis in broccoli; the reduction in ethylene production during senescence resulted from the degradation of the system that converts ACC to ethylene. Chemical name used: 1-aminocyclopropane-1-carboxylic acid (ACC).
Single-Delta Bridge-Cell Converter With Single Single-Phase Medium-Frequency Transformer Capable of Active Power Control

A modular multilevel cascade converter based on single-delta bridge cells, hereinafter referred to as the single-delta bridge-cell (SDBC) converter, is a prospective power converter for a static synchronous compensator intended for voltage regulation and stability improvement of electric power systems. However, the SDBC converter cannot exchange nonzero active power with the three-phase ac mains unless energy storage elements such as batteries are connected to the dc side of each bridge cell. This article presents a dc/1<inline-formula><tex-math notation="LaTeX">$\phi$</tex-math></inline-formula>/3<inline-formula><tex-math notation="LaTeX">$\phi$</tex-math></inline-formula> power converter that combines the SDBC converter with a single-phase converter via a single-phase medium-frequency transformer with an operating frequency of 150 Hz. It can control the active power of 37% of the rated reactive power between the dc source and three-phase ac mains, thus enhancing voltage regulation and stability improvement. The operating principles and control method are first discussed, followed by a description of experiments using a downscaled 110-V, 5-kVA model.
Facile synthesis of Ni/NiO nanocomposites: the effect of Ni content in NiO upon the oxygen evolution reaction within alkaline media

We present the facile synthesis of Ni/NiO nanocomposites, via a solution combustion methodology, where the composition of metallic Ni within NiO is controlled by varying the annealing time, from 4 minutes up to 8 hours. The various Ni/NiO nanocomposites are studied via electrically wiring them upon screen-printed graphite macroelectrodes by physical deposition. Subsequently their electrochemical activity, towards the oxygen evolution reaction (OER), is assessed within (ultra-pure) alkaline media (1.0 M KOH). An optimal annealing time of 2 hours is found, which gives rise to an electrochemical oxidation potential (recorded at 10 mA cm−2) of 231 mV (vs. Ag/AgCl 1.46 vs. RHE). These values show the Ni/NiO nanocomposites to be significantly more electrocatalytic than a bare/unmodified SPE (460 mV vs. Ag/AgCl). A remarkable percentage increase (134%) in achievable current density is realised by the former over that of the latter. Tafel analysis and turn over frequency is reported with a likely underlying mechanism for the Ni/NiO nanocomposites towards the OER proposed. In the former case, Tafel analysis is overviewed for general multi-step overall electrochemical reaction processes, which can be used to assist other researchers in determining mechanistic information, such as electron transfer and rate determining steps, when exploring the OER. The optimal Ni/NiO nanocomposite exhibits promising stability at the potential of +231 mV, retaining near 100% of its achievable current density after 28 hours. Due to the facile and rapid fabrication methodology of the Ni/NiO nanocomposites, such an approach is ideally suited towards the mass production of highly active and stable electrocatalysts for application within the anodic catalyst layers of commercial alkaline electrolysers.
Double-View Matching Network for Few-Shot Learning to Classify Covid-19 in X-ray images

The research topic presented in this paper belongs to small training data problem in machine learning (especially in deep learning), it intends to help the work of those working in medicine by analyzing pathological X-ray recordings, using only very few images. This scenario is a particularly hot issue nowadays: how could a new disease for which only limited data are available be diagnosed using features of previous diseases? In this problem, so-called few-shot learning, the difficulty of the classification task is to learn the unique feature characteristics associated with the classes. Although there are solutions, but if the images come from different views, they will not handle these views well. We proposed an improved method, so-called Double-View Matching Network (DVMN based on the deep neural network), which solves the few-shot learning problem as well as the different views of the pathological recordings in the images. The main contribution of this is the convolutional neural network for feature extraction and handling the multi-view in image representation. Our method was tested in the classification of images showing unknown COVID-19 symptoms in an environment designed for learning a few samples, with prior meta-learning on images of other diseases only. The results show that DVMN reaches better accuracy on multi-view dataset than simple Matching Network without multi-view handling.
Correlation of macro-micro mineral status with parasitic infection in captive wild carnivores of Chhattisgarh, India

Nineteen native Bacillus thuringiensis (Bt) strains isolated from soil samples were evaluated against III instar grubs of Tribolium castaneum (H.) at College of Agriculture, Bheemarayanagudi, University of Agricultural Sciences, Raichur during 2018-19. The laboratory bioassays revealed that III instar T. castaneum grubs were treated with 19 native Bt isolates showed mortality in range of 33.33 to 93.33% during preliminary screening. Highest mortality of 93.33% was recorded in RCM-2, which was on par with the native Bt isolate, GHM-2(86.66%). Next best treatment was found to be in Bt isolates BGC-2, RCM-1 and MDH were registered similar mortality of 83.33 per cent. Lowest mortality of 33.33 per cent was recorded in Bt isolate GPP-1. No mortality was recorded in HD-1 reference strain since it is specific to lepidopteran insect pests and in untreated control against III instar grubs of T. castaneum. During preliminary screening 94.73% of the Bt isolates (18/19) tested against III instar T. castaneum grubs registered more than 50% mortality. Median lethal concentration of the native isolates (RCM-2 and GHM-2) of Bt were recorded more than 85 per cent mortality in preliminary screening revealed that the toxicity of those two potential B. thuringiensis isolates against third instar grubs of T. castaneum ranged from 8.21 to 20.11μg/ml. Among two potential isolates tested, isolate RCM-2 showed the least LC50 value of 8.21μg/ml and followed by GHM-2 (20.11 μg/ml).
Enhancing Charge Separation in Metallic Photocatalysts: A Case Study of the Conducting Molybdenum Dioxide

A new visible‐light responsive metallic photocatalyst, nanostructured MoO2, has been discovered. The metallic nature of MoO2 is confirmed by valance X‐ray photoelectron spectroscopy spectrum and theoretical calculations. However, MoO2 itself shows only moderate activity due to the serious charge recombination, a general disadvantage of metallic photocatalysts. The findings suggest that its effective charge diffusion length Lp is smaller than 1.0 nm while the separation efficiency ηsep is less than 10%. Therefore, only the periphery of the metallic MoO2 can effectively contribute to photocatalysis. This limitation is overcome by integrating MoO2 in a hydrothermal carbonation carbon (HTCC) matrix (mainly contains semiconductive polyfuran). This simple chemical modification brings two advantages: (i) an internal electric field is formed at the interface between MoO2 and HTCC due to their appropriate band alignment; (ii) the nanostructured MoO2 and the HTCC matrix are intertwined with each other intimately. Their small size and large contact area promote charge transfer, especially under the internal electric field. Therefore, the separation rate of photoexcited charge carrier in MoO2 is greatly enhanced. The activity increases by 2.4, 16.8, and 4.0 times in photocatalytic oxygen evolution, dyes degradation, and photoelectrochemicl cell, respectively. The new approach is helpful for further development of metallic photocatalysts.
