Authors: Kolmakova T S , Morgul E V , Belik S N , Slozhenkina M I , Morgul A R 
Published: September 2020

AbstractLiving in environmentally neglected areas, stress, imbalance in the diet, and a decrease in the immune status adversely affect the human body. One of the main disorders is an imbalance in the intestinal biocenosis. Disorders of the intestinal microflora lead to diseases of the gastrointestinal tract, cardiovascular system, obesity, diabetes, malignant neoplasms, allergic autoimmune diseases, and mental disorders. Imbalance of the intestinal microflora causes inflammatory processes and, therefore, DNA damage. Prebiotics are a means to restore intestinal microbiota. This article provides information on the study of an antimutagenic effect of prebiotics. We studied a monocomponent preparation, containing lactulose and a multicomponent prebiotic that consisted of aqueous substrates of metabolic products Escherichia coli DSM 4087, Streptococcus faecalis DSM 4086, Lactobacillus acidophilus DSM 4149, and Lactobacillus helveticus DSM 4183. The purpose of the investigation was to study antigenotoxic properties of the preparations. The preparations’ ability to suppress genotoxicity caused by oxidative stress was evaluated by the biosensor bacteria’s ability to reduce the DNA damage caused by dioxidine—an endogenous generator of reactive oxygen species (ROS). To detect DNA damage in a cell, E. coli MG1655 biosensors with pRecA and pColD promoters were used. The studied prebiotics were found to exhibit a weak antigenotoxic effect, regardless of the composition or a range of concentrations applied. A monocomponent preparation (lactulose) had much better protective effect than a metabolic-type prebiotic that contained metabolic products of Escherichia coli, enterococci and lactobacilli. The study results may be taken into account in selection of prebiotic components as functional ingredients with antigenotoxic and antioxidant properties in the food industry.

Published: September 2020

Abstract
The article considers the replaceability of a part of raw meat with plant material, in particular, flax meal and pumpkin in order to develop a product for elderly people. For the same purpose, the proposed formulation was added with calcium citrate produced according to a new technology intended to enrich the product with calcium—one of the most important macroelements. The study has selected optimal amount of plant ingredients introduced that did not spoil the sensory properties of the product. The main physicochemical parameters, i.e., weight fractions of protein and fat and amino acid composition, were examined. It was concluded that the developed formulation makes it possible to obtain a low-calorie high-protein calcium-enriched product intended for gerodietetic nutrition. Replacing a part of raw meat with plant materil can also reduce the finished product cost.

Abstract
The aim of our study was to study the effect of prebiotic components on the quality indicators of enriched yogurt. Yogurt was produced by fermenting pasteurized normalized milk with yoghurt sourdough, which included lyophilically dried strains of Streptococcus thrmophilus, Lactobacillus delbrueckii ssp.bulgaricus, Lactobacillus acidophilus, and Bactidiochemia sulphonidae with the addition of lactobacillus cultivar and yeast lactobacillus complex ), in addition, in order to enrich the product with vitamins, minerals and polyphenolic compounds, mashed potatoes from blueberries and dogwood were used. In the course of the study, we evaluated organoleptic, physicochemical and microbiological indicators, carried out a comparative analysis of the content of vitamins and trace elements in a traditional and enriched product. It was established that enrichment of yogurt with a prebiotic complex and fruit and berry puree contributed to the improvement of quality indicators, due to an increase in nutritional value, an increase in the content of vitamins (C, B1, B2, E and PP) and microelements (Ca, K, Mg, P, Fe). The prebiotic properties and immunogenic effects of wheat bran and yeast cell wall components, as well as the polyphenolic compounds of blueberries and cornel berries, make it possible to use yogurt as an adaptogenic product with probiotic, prebiotic neuroprotective, cardioprotective, antioxidant, immunomodulating and anti-inflammatory properties.

Published: September 2020

Abstract
According to the research by the Lighthouse company, energy consumption in the Russian industry exceeds the level of similar enterprises in other countries by 40-220%. In this regard, the study of energy consumption for production and selection of rational parameters using a new hardware design of processes is an urgent task. As research object a line for the production of granulated feed was selected. Based on the results of literature data analysis and patent review, a new design of drum vibration device with controlled segregate flows was proposed. The results of study of specific energy consumption for the drying process allowed to determine the percentage ratio between the values of energy consumption from each component of the process, and the coefficient of accounting for the conditional moisture evaporated from the granules. It allowed establishing rational parameters of the process. The use of phase volume characteristics of dispersed systems allows to improve the method for determining the thermal characteristics of dry and wet dispersed systems. The application of the developed methods will significantly reduce energy costs for the production of granulated feed, which eventually creates a competitive enterprise.

Abstract
One of the key factors ensuring the increase in sheep production in future is the development of intensive reproduction of the herd. The article presents the results of an experiment that helped study and give comparative characteristics for the meat productivity and natural resistance of the pedigree Edilbay sheep breed in conditions of a pedigree reproducer in 2018-2019. The young stocks of original and new types were studied to assess their interior traits, establish the direction and degree of correlation between the biochemical blood parameters and meat productivity of young sheep, as well as determine indices reflecting the immune status of organisms of the experimental sheep. When starting the test, the live weight of animals of the pure and pedigree types were almost the same, while when finishing the experiment at the age of 12 months, animals in Group II exceeded animals in Group I by 4.3 kg (5.8%, P<0.01). The best average daily gain of experimental sheep was also in Group II, i.e., 167 g, which was higher than in Group I by 9.1% (P<0.01). Consequently, the rams of new type had the highest growth rate. The data of the control slaughter showed that both experimental groups had high meat productivity. The analysis of natural resistance indicators of small ruminants of various types and their relationship with productive qualities in different climatic zones have also shown the need to use different integral indicators to assess the immune status in further breeding of animals. The analysis of natural resistance indicators of small ruminants of various types and their relation with productive qualities in different climatic zones has suggested that there is a need to use several markers to assess the immune status for further sheep breeding.
Design of a terahertz metamaterial sensor based on split ring resonator nested square ring resonator
Authors: Chen Tao , Zhang Dapeng , Huang Fengyu , Li Zhi , Hu Fangrong 
Published: September 2020

Abstract
A terahertz (THz) sensor based on the metamaterial structure, split ring resonator with four-gaps relied on centrosymmetric nested square ring resonator, is presented. The two resonant elements of the metamaterial structure generate a corresponding resonant valley on the transmission spectrum curve in the frequency range from 0.1 to 1.9 THz respectively, and both of these resonant valleys show different redshifts when the surface permittivity of the structure changes. This feature is very suitable for THz sensing, especially the quantum interference effect between the two resonant elements, which results in the formation of an electromagnetically induced transparency (EIT)-like resonance peak on the transmission spectrum curve. The sensing performances are simulated by using commercialized full-wave electromagnetic simulation software. The results demonstrated that the proposed sensor is polarization-insensitive and has a highly boosted sensitivity, which has a promising application prospect in the fields of biomedical science and drug industry.
Relativistic J-matrix method of scattering in 1 + 1 space-time I. Theory
*
Authors: Alhaidari A D 
Published: September 2020

Abstract
We make a relativistic extension of the one-dimensional J-matrix method of scattering. The relativistic potential matrix is a combination of vector, scalar, and pseudo-scalar components. These are non-singular short-range potential functions (not necessarily analytic like a square well) such that they are well represented by their matrix elements in a finite subset of a square integrable basis set. This set is chosen to support a tridiagonal symmetric matrix representation for the free Dirac operator. We derive the transmission and reflection coefficients. This work will be followed by another where we apply the theory to obtain scattering information for different potential coupling modes including those with evidence of Klein tunneling and of supercritical resonances.

Published: September 2020

Abstract
Programmable control of the inductive electric field enables advanced operations of reversed-field pinch (RFP) plasmas in the Madison Symmetric Torus (MST) device and further develops the technical basis for ohmically heated fusion RFP plasmas. MST’s poloidal and toroidal magnetic fields (B
p and B
t) can be sourced by programmable power supplies (PPSs) based on integrated-gate bipolar transistors (IGBT). In order to provide real-time simultaneous control of both B
p and B
t circuits, a time-independent integrated model is developed. The actuators considered for the control are the B
p and B
t primary currents produced by the PPSs. The control system goal will be tracking two particular demand quantities that can be measured at the plasma surface (r = a): the plasma current, I
p ∼ B
p(a), and the RFP reversal parameter, F ∼ B
t(a)/Φ, where Φ is the toroidal flux in the plasma. The edge safety factor, q(a) ∝ B

t
(a), tends to track F but not identically. To understand the responses of I
p and F to the actuators and to enable systematic design of control algorithms, dedicated experiments are run in which the actuators are modulated, and a linearized dynamic data-driven model is generated using a system identification method. We perform a series of initial real-time experiments to test the designed feedback controllers and validate the derived model predictions. The feedback controllers show systematic improvements over simpler feedforward controllers.
Synthesis mechanism of SiC–SiO2 core/shell nanowires grown by chemical vapor deposition
Authors: Finetti F , Cavalli E , Attolini G , Rossi F 
Published: September 2020

Abstract
Core–shell SiC–SiO2 nanowires were grown on silicon substrate with the chemical vapor deposition method using iron nitrate as promoter for the growth and CO as a carbon precursor, under atmospheric pressure and at a temperature of 1100 °C. The whole process involves two main stages: promoter conditioning (dewetting) and growth, by reaction with CO. The dewetting phase has been characterized by SEM and TEM techniques, x-ray diffraction and Raman spectroscopy. The results show that at the operating temperature, a solid-state reaction between the substrate and the promoter takes place with the formation of α-FeSi2. The growth of the nanowires begins after an induction time of about 5 min from the introduction of CO. The experimental data have been interpreted by considering a nucleation process involving a reaction between FeSi2 and CO. For the nanowires growth phase, a mechanism based on the Vapor-Liquid-Solid theory is proposed, compatible with the morphology of the drop-shaped particles present on the tip of the nanowires.
Why change your beliefs rather than your desires? Two puzzles
Authors: Vassend Olav Benjamin 
Published: September 2020

Abstract
In standard decision theory, the probability function ought to be updated in light of evidence, but the utility function generally stays fixed. However, there is nothing in the formal theory that prevents one from instead updating the utility function, while keeping the probability function fixed. Moreover, there are good arguments for updating the utilities and not just the probabilities. Hence, the first puzzle is whether there is anything that justifies updating beliefs, but not desires, in light of evidence. The paper argues that there is not, but that this raises a second puzzle .

Published: September 2020

AbstractThis article employs a queer of color critique as a theoretical lens to analyze the experiences of queer activists of color involved in mobilizing against oppressive laws in Texas. Through a queer of color critique, this interview-based study analyzes the internal power dynamics within a political campaign to uncover how they shaped the possibilities afforded to queer persons of color, what strategies queer people of color developed for resisting power and asserting agency, and how queer of color critique informs public relations theory. The purpose of this article is to advance critical work in public relations research, a commitment that is significant for critical and cultural communication studies.
Introducing Typhoid Conjugate Vaccine in South Asia: Lessons From the Surveillance for Enteric Fever in Asia Project
Authors: Carter Alice S , Luby Stephen P , Garrett Denise O 
Published: September 2020

AbstractEnteric fever remains a public health concern in communities lacking sanitation infrastructure to separate sewage from drinking water. To bridge the gap until large-scale civil-engineering projects are implemented in high-burden countries, typhoid conjugate vaccine presents a promising disease-prevention technology. A new typhoid conjugate vaccine was prequalified by the World Health Organization in 2017 and is beginning to be introduced in countries around the world. To help inform vaccine introduction, the Surveillance for Enteric Fever in Asia Project (SEAP) conducts prospective enteric fever surveillance in Bangladesh, Nepal, and Pakistan. This supplement presents findings from Phase II of the study (2016–2019) on burden of disease, clinical presentation, the growing spread of drug-resistant strains, and policy and economic ramifications. These findings are delivered to support policymakers in their deliberations on strategies to introduce typhoid conjugate vaccine as a preventive tool against enteric fever.
Using multilayer network analysis to explore the temporal dynamics of collective behavior
Authors: Fisher David N , Pinter-Wollman Noa 
Published: September 2020

Abstract
Social organisms often show collective behaviors such as group foraging or movement. Collective behaviors can emerge from interactions between group members and may depend on the behavior of key individuals. When social interactions change over time, collective behaviors may change because these behaviors emerge from interactions among individuals. Despite the importance of, and growing interest in, the temporal dynamics of social interactions, it is not clear how to quantify changes in interactions over time or measure their stability. Furthermore, the temporal scale at which we should observe changes in social networks to detect biologically meaningful changes is not always apparent. Here we use multilayer network analysis to quantify temporal dynamics of social networks of the social spider Stegodyphus dumicola and determine how these dynamics relate to individual and group behaviors. We found that social interactions changed over time at a constant rate. Variation in both network structure and the identity of a keystone individual was not related to the mean or variance of the collective prey attack speed. Individuals that maintained a large and stable number of connections, despite changes in network structure, were the boldest individuals in the group. Therefore, social interactions and boldness are linked across time, but group collective behavior is not influenced by the stability of the social network. Our work demonstrates that dynamic social networks can be modeled in a multilayer framework. This approach may reveal biologically important temporal changes to social structure in other systems.

Abstract

Aims
Risk stratification of sudden cardiac arrest (SCA) in Brugada syndrome (Brs) remains the main challenge for physicians. Several scores have been suggested to improve risk stratification but never replicated. We aim to investigate the accuracy of the Brs risk scores.

Methods and results
A total of 1613 patients [mean age 45 ± 15 years, 69% male, 323 (20%) symptomatic] were prospectively enrolled from 1993 to 2016 in a multicentric database. All data described in the risk score were double reviewed for the study. Among them, all patients were evaluated with Shanghai score and 461 (29%) with Sieira score. After a mean follow-up of 6.5 ± 4.7 years, an arrhythmic event occurred in 75 (5%) patients including 16 SCA, 11 symptomatic ventricular arrhythmia, and 48 appropriate therapies. Predictive capacity of the Shanghai score (n = 1613) and the Sieira (n = 461) score was, respectively, estimated by an area under the curve of 0.73 (0.67–0.79) and 0.71 (0.61–0.81). Considering Sieira score, the event rate at 10 years was significantly higher with a score of 5 (26.4%) than with a score of 0 (0.9%) or 1 (1.1%) (P &lt; 0.01). No statistical difference was found in intermediate-risk patients (score 2–4). The Shanghai score does not allow to better stratify the risk of SCA.

Conclusions
In the largest cohort of Brs patient ever described, risk scores do not allow stratifying the risk of arrhythmic event in intermediate-risk patient.
Getting to the Heart of the Matter in Later Life: The Central Role of Affect in Health Message Framing
Authors: Mikels Joseph A , Young Nathaniel A , Liu Xiaomei , Stine-Morrow Elizabeth A L 
Published: September 2020

Abstract

Background and Objectives
Adopting healthy behaviors is often influenced by message framing; gain-framed messages emphasize the benefits of engaging in a behavior, whereas loss-framed messages highlight the consequences of not engaging in a behavior. Research has begun to uncover the underlying affective pathways involved in message framing. In the current study, we examined the role of affect in message framing to encourage exercise program enrollment among older adults.

Research Design and Methods
We mailed flyers to 126 volunteers assigned to a gain- or loss-framed condition and measured their affective reactions to the flyer and enrollment intentions. After the call, participants had the opportunity to contact us to enroll.

Results
Gain versus loss framing led to more positive affect toward the flyer, which predicted intentions and enrollment effort. In indirect effect analyses, frame indirectly influenced intentions and enrollment effort via positive affect.

Discussion and Implications
Although message framing plays an indirect role in influencing behavior, affect plays a central role.

Published: September 2020

Abstract
Renewable energy technologies have been developed in recent years due to the limited sources of fossil fuels, the possibility of depletion of fossil fuels and the related environmental issues. In these types of systems, it is crucial to reach optimum sizing in order to have an affordable system based on solar and wind energy and energy storage. In this study, a powerful optimization scheme based on tabu search, called discrete tabu search, has been proposed for sizing three stand-alone solar/wind/energy storage (battery) hybrid systems. For validating the applied algorithm effectiveness, the results are compared with the results found by the discrete harmony search. The obtained outcomes are compared on the basis of total annual cost. The components of the scheme are analyzed in different operating conditions by applying meteorological data in addition to real time information from three typical regions of Iran. According to the obtained data, applying ‘discrete tabu search’ leads to better outputs on the basis of mean, standard deviation and worst indexes.
