An intuitive risk factors search algorithm: usage of the Bayesian network technique in personalized medicine

The article focuses on the application of the Bayesian networks (BN) technique to problems of personalized medicine. The simple (intuitive) algorithm of BN optimization with respect to the number of nodes using naive network topology is developed. This algorithm allows to increase the BN prediction quality and to identify the most important variables of the network. The parallel program implementing the algorithm has demonstrated good scalability with an increase in the computational cores number, and it can be applied to the large patients database containing thousands of variables. This program is applied for the prediction for the unfavorable outcome of coronary artery disease (CAD) for patients who survived the acute coronary syndrome (ACS). As a result, the quality of the predictions of the investigated networks was significantly improved and the most important risk factors were detected. The significance of the tumor necrosis factor-alpha gene polymorphism for the prediction of the unfavorable outcome of CAD for patients survived after ACS was revealed for the first time.
VLSP 2021 - vnNLI Challenge: Vietnamese and English-Vietnamese Textual Entailment

This paper presents the first challenge on recognizing textual entailment (RTE), also known as natural language inference (NLI), held in a Vietnamese Language and Speech Processing workshop (VLSP 2021). The challenge aims to determine, for a given pair of sentences, whether the two sentences semantically agree, disagree, or are neutral/irrelevant to each other. The input sentences are in English or Vietnamese and may not be in the same language. This task is important in identifying, from different information sources, the evidence that supports or refutes a statement. The identification of such evidence is subsequently useful for many information tracking applications, such as opinion mining, brand and reputation management, and particularly fighting against fake news.Through this challenge, we would like to provide an opportunity for participants who are interested in the problem, to contribute their knowledge to improve the existing techniques and methods for the task, so as to enhance the effectiveness of those applications.In the paper, we introduce a collection of Vietnamese and English sentences in the domain of health that we built to serve as a benchmarking dataset for the task. We also describe the evaluation results of systems participating in the challenge.
Informative and uninformative prestimulus cues at encoding benefit familiarity and source memory

ABSTRACT Previous research has shown that neural activity elicited by informative prestimulus cues during encoding differ with respect to subsequent memory outcomes. These findings indicate prestimulus cues create a “brain state” associated with subsequent memory that, potentially, also has downstream effects benefitting processes associated with successful encoding and subsequent memory performance. However, previous studies have not included the conditions necessary to appropriately test this latter assumption. The present study examines how informative and uninformative prestimulus encoding cues affect memory accuracy for upcoming stimuli compared to a no cue condition. At encoding, participants made one of two semantic judgments on words preceded by an informative prestimulus cue that identified the upcoming semantic judgment, an uninformative prestimulus cue that signalled an upcoming trial but no information about the semantic judgment, or no cue. Dual process estimates of familiarity, but not recollection, demonstrated a graded pattern with the informativeness of the prestimulus cues (i.e., informative > uninformative > no cues). Moreover, both informative and uninformative prestimulus cues enhanced subsequent source memory accuracy for the encoding task compared to the no cue condition. These findings suggest that prestimulus cues can strengthen the processes that support successful memory encoding and benefit subsequent familiarity and source memory.

Graphical Abstract Summary:Salmonella enterica sv. Dublin inoculated into sterile bedding sand can survive and proliferate when incubated at room temperature for up to 7 days. However, inoculation of Salmonella enterica sv. Dublin into bedding sand that contains a naturally occurring microbiota results in a decrease in cfu of Salmonella enterica sv. Dublin under the same conditions.
Antecedents of Return on Assets in Covid-19 Pandemic: Do LDR, CAR, OE and Bank Size Matters?

This study examines the effect of LDR, CAR, OE, and Bank Size on ROA. The population in this study, namely, Conventional Commercial Banks listed on the Indonesia Stock Exchange (IDX) for the 2020-2021 period amounted to 43 banks. The determination of the sample was carried out using the purposive sampling technique so that 62 research observations were obtained. The analysis used is multiple linear regression. The results showed that the LDR, CAR, and bank size have no effect, while OE have a significant negative effect on ROA. This research is expected to be an additional reference and information for subsequent researchers and academies in the field of accounting and investors during Covid-19 pandemic regarding investment decisions by considering the factors that affect ROA.
Study of Evaporation and Instability of Charged Water Droplets.

Abstract The wind correction to the evaporation rate of electrically suspended water droplets has been measured for Reynolds numbers between 1 and 6. The results agree well with those of Kinzer and Gunn. During evaporation, Rayleigh instabilities have also been observed. At instability, the charge variation ΔQ is of the same order as that observed by other workers, but under the present experimental conditions there is no detectable change of mass.
Nanoscale disorder in high critical field, carbon-doped MgB2 hybrid physical-chemical vapor deposition thin films

Carbon-doped MgB2 thin films deposited by hybrid physical-chemical vapor deposition (HPCVD) can have Hc2(0K)∼70T, anomalously high compared to bulk samples which have Hc2 about half this value. Using transmission electron microscopy, the authors show that the carbon content in HPCVD-grown Mg(B1−xCx)2 grains is x⩽5%, and that most carbon forms an amorphous intergranular phase. The authors also find extensive structural disorder, including rotations about the c axis and small tilts of the c axis, with a domain size of 5–20nm. The authors propose that strong electron scattering from the nanoscale disorder is responsible for the very high Hc2 in such films.
Potential analysis of hydrogen energy technology in the power grid based on carbon tax: A case study in Japan

Electrolytic hydrogen storage technology of renewable energy is considered as one of the important measures to realize the high proportion of renewable energy. However, developing this technology has been slow due to the cost. This study proposes highlighting the environmental advantages of renewable power combined with a carbon tax at the national level to expand the application space of hydrogen storage technology. First, the economy and technical characteristics of hydrogen storage technology and conventional energy-storage technology were compared. Then, Japan's top 10 power companies, which account for 90% of the power supply, were taken as the research objects. The proportion of change in renewable power after introducing a carbon tax was studied, taking the weighted minimum of the feed-in tariffs as the optimization objective. The contribution of hydrogen storage technology to the change in renewable power share was analyzed. Next, a sensitivity analysis was conducted on the fossil energy price and cost of renewable power equipment that affects the research. Finally, the contribution of a carbon tax and hydrogen storage technology to Japan's emission reduction target was calculated and analyzed. The results showed that the characteristics of long-distance transportation of hydrogen energy and making renewable energy have economic advantages under the current carbon tax (5–6 JPY/kg-CO2). The cost of liquified natural gas (LNG) and the investment of photovoltaic (PV) have a significant impact on the weighted minimum feed-in price, which can make the development of hydrogen storage technology no longer rely on the setting of carbon tax. The results obtained in this study provide a theoretical reference for the application of hydrogen storage technology in the high proportion of renewable energy consumption. At the same time, it can also provide data reference for large-scale construction of renewable energy in regions where solar and wind energy resources are not excellent.
Laboratory applications of truncated parametric arrays.

Parametric arrays have characteristics that make them ideally suited for use as versatile sources in the laboratory for performing a range of measurements and acoustic studies. Such measurements can exploit the wideband character of the source to provide detailed acoustic response characteristics of systems as a function of frequency, while the short pulses and narrow beamwidths enable multiple reflections and unwanted echoes to be resolved or minimized. However, the need to make measurements in the nearfield of the array means that truncation of the nonlinear interaction region with an acoustic low‐pass filter is advisable in order to generate a region free of secondary‐sources and simplify the interpretation of the results. This truncation also avoids the possible influence of hydrophone nonlinearity. The effects of truncation on the array characteristics are illustrated using both model and experimental results. A number of examples of the use of arrays in the laboratory are given, including their use .
Sommerfeld's elliptical atomic orbits revisited—A useful preliminary to the study of quantum mechanics

The Bohr-Sommerfeld atomic model is recast in the language of wave-particle duality and it is shown that requirements equivalent to the Sommerfeld-Wilson quantisation conditions arise naturally in this context. It is suggested that treating the one-electron atom in this way provides a useful introduction for students prior to encountering the more formal analysis based on the solution of the Schrodinger equation.
Circadian clock control of tRNA synthetases in Neurospora crassa

Background: In Neurospora crassa, the circadian clock controls rhythmic mRNA translation initiation through regulation of the eIF2α kinase CPC-3 (the homolog of yeast and mammalian GCN2). Active CPC-3 phosphorylates and inactivates eIF2α, leading to higher phosphorylated eIF2α (P-eIF2α) levels and reduced translation initiation during the subjective day. This daytime activation of CPC-3 is driven by its binding to uncharged tRNA, and uncharged tRNA levels peak during the day under control of the circadian clock. The daily rhythm in uncharged tRNA levels could arise from rhythmic amino acid levels or aminoacyl-tRNA synthetase (aaRSs) levels. Methods: To determine if and how the clock potentially controls rhythms in aspartyl-tRNA synthetase (AspRS) and glutaminyl-tRNA synthetase (GlnRS), both observed to be rhythmic in circadian genomic datasets, transcriptional and translational fusions to luciferase were generated. These luciferase reporter fusions were examined in wild type (WT), clock mutant Δ frq, and clock-controlled transcription factor deletion strains. Results: Translational and transcriptional fusions of AspRS and GlnRS to luciferase confirmed that their protein levels are clock-controlled with peak levels at night. Moreover, clock-controlled transcription factors NCU00275 and ADV-1 drive robust rhythmic protein expression of AspRS and GlnRS, respectively. Conclusions: These data support a model whereby coordinate clock control of select aaRSs drives rhythms in uncharged tRNAs, leading to rhythmic CPC-3 activation, and rhythms in translation of specific mRNAs.
Methane Production Linked to Organic Matter Molecule and Methanogenic Community in Estuarine Benthic Sediments

The importance of dissolved organic matter (DOM) and methanogenic community to methane (CH4) production in estuarine benthic sediments remains poorly understood. Here, we determined CH4 production rate, DOM molecule, and methanogenic community in benthic sediments of Min River Estuary. CH4 production rates in freshwater and saline sediments varied between 0.28 and 0.56 μg CH4 m−2 h−1, and between 0.17 and 0.27 μg CH4 m−2 h−1, respectively. CH4 production rates in freshwater sediments were increased by 36%–66% under saline incubation, compared to freshwater incubation, indicating that elevated salinity can stimulate CH4 production. The δ13C‐CH4 decreased and fractionation factor between δ13C‐CO2 and δ13C‐CH4 increased from high‐ to low‐OM sediments, suggesting a shift of CH4 production from acetoclastic to hydrogenotrophic pathways. A decrease in labile fractions and an increase in recalcitrance fractions of DOM were accompanied by the decrease in CH4 production. The Methanoregula, Methanocellales, Methanosarcina, and Methanosaeta were the predominant methanogenic communities in mediating CH4 production. The differences in DOM molecules and methanogenic archaea taxa could drive the distinct CH4 production rates in estuarine benthic sediments. These results suggest that DOM quantity and molecules and methanogenic archaea can substantially affect CH4 production, which have broader implications for global CH4 estimates under the ongoing eutrophication in estuarine and coastal ecosystems.
Turbulent Structure of Gaseous Detonation

Self‐sustaining and overdriven detonations in 2H2 + O2 + 2CO have been studied in a shock tube at initial pressures from 0.01 to 1.4 atm. Measurements have included pressure, density obtained interferometrically, and luminosity whose intensity is shown to be proportional to [CO][O]. Strongly overdriven waves are one dimensional and are followed by the calculated equilibrium state. Self‐sustaining detonations are followed by a state in which the pressure and density are lower than calculated according to the usual C‐J hypothesis, and in which the flow is supersonic with respect to the wave front. Furthermore, the flow in and behind the reaction zone invariably appears to be turbulent. In an examination of the implications of this turbulence, a Chapman‐Jouguet detonation is considered to be one with the minimum velocity of propagation which will satisfy the conservation relations for turbulent flow at the rear of reaction zone. It is shown that this minimum (C‐J) velocity is slightly greater than that calcu.
How Does Consistency of Food and Nutrition Support Effect Daily Food Consumption among Children Living in Poverty? Recession-Era Implications

Underutilization of the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) and the Supplemental Nutrition Assistance (SNAP) food safety net programs may compromise child nutritional benefits for families with limited incomes. Using a sample of children surveyed before (2003–2006) and after the Great Recession (2007–2009), we examine whether consistent access to WIC and SNAP during times of increased economic stress moderated the association between poverty level (i.e., income-needs ratio [INR]) and fruits and vegetables (FV) or foods high in saturated fats and added sugars (SFAS). Fragile Families and Child Wellbeing Study income-eligible mothers/children (≤185% of poverty) with available FV and SFAS data at the 5- (2003–2006) and 9-year (2007–2010) waves (n = 733) were included. Main effects of INR and interaction effects of consistency of WIC, SNAP, and dual WIC and SNAP support from birth through age 5 were examined. INR was associated with decreased FV consumption frequency from age 5 to 9, conditional upon consistency of dual WIC/SNAP enrollment. FV declined when there was low consistency (<1 year) of dual support. FV consumption was stable across INR when combined WIC/SNAP support lasted at least 2 years. Results can inform strategies for optimizing the nutritional impact of WIC and SNAP by focusing on those most at risk for underutilization of multiple benefits.
Biological Activity of Amidino-Substituted Imidazo [4,5-b]pyridines

A series of cyano- and amidino-substituted imidazo[4,5-b]pyridines were synthesized using standard methods of organic synthesis, and their biological activity was evaluated. Biological evaluation included in vitro assessment of antiproliferative effects on a diverse selection of human cancer cell lines, antibacterial activity against chosen Gram-positive and Gram-negative bacterial strains, and antiviral activity on a broad panel of DNA and RNA viruses. The most pronounced antiproliferative activity was observed for compound 10, which contained an unsubstituted amidino group, and compound 14, which contained a 2-imidazolinyl amidino group; both displayed selective and strong activity in sub-micromolar inhibitory concentration range against colon carcinoma (IC50 0.4 and 0.7 μM, respectively). All tested compounds lacked antibacterial activity, with the exception of compound 14, which showed moderate activity against E. coli (MIC 32 μM). Bromo-substituted derivative 7, which contained an unsubstituted phenyl ring (EC50 21 μM), and para-cyano-substituted derivative 17 (EC50 58 μM) showed selective but moderate activity against respiratory syncytial virus (RSV).
The bridge between first-principles calculations and grand canonical Monte Carlo simulations: Morse and Lennard-Jones force fields

We use the modelled adsorbate (methane) and adsorbent (carbon nanotube) to explore the choice of site-to-site force fields in order to bridge the gap between first-principles calculation and grand canonical Monte Carlo. By using the mature classical Lennard-Jones potential-based results as benchmark, it is found if the first-principles calculation is performed at the higher MP2/6-311G** level, Morse potential model should be adopted to achieve the force field parameters. It is expected that this work provides useful information for the building of the multiscale simulation method and the selection of accurate force field models.
Strain sensor based on cellulose ZnO hybrid nanocomposite

ZnO is well known semiconductor material with high band gap as well as piezoelectricity. Because of its high performance of electromechanical behavior, ZnO based piezoelectric devices have taken great attention from many research groups. However, ZnO should be grown on a flexible substrate so as to allow its flexibility. Since cellulose is renewable, flexible and biocompatible, ZnO is grown on cellulose by hydrothermal process, then a novel flexible piezoelectric material. We report the fabrication and strain sensor behavior of cellulose ZnO hybrid nanocomposite(CEZOHN) In this research, simple piezoelectric strain sensor based on CEZOHN is made by directly stretching it and by boding it on a cantilever. Its performance is measured in terms of longitudinal and bending strain. This strain sensor shows a good linearity.

Comptonization of thermal photons by relativistic electron beams

This paper presents a numerical calculation of gamma-ray emission produced by Compton scattering of relativistic electron beams on background thermal radiation, which includes spatial dependence of electron energy losses and cyclotron resonance scattering in a strong magnetic field. In the first version, the scattering is described by the fully relativistic Klein-Nishina cross section, but the magnetic field is neglected. In the second version, the scattering is described by the magnetic resonant cross section in the Thomson limit. It is found that when the magnetic field is not included, electron energy losses are important only at higher neutron star surface temperatures (T about 3,000,000 K). In the presence of a strong magnetic field, (10 to the 12th G), resonant scattering greatly increases electron energy losses, making scattering very efficient even at lower surface temperatures. Resulting photon and electron spectra for both cases ae discussed in relation to models for pulsar X-ray and gamma-ray emission. 26 references.
