Correlation of MR pulmonary perfusion in patients with COVID-19 with quantitative assessment of acute phase CT images
Authors: Zakharova A. V. 
Published: October 2023

INTRODUCTION: In the last decade, there has been an increased interest in new diagnostic techniques for assessing quantitative values in radiology. In particular, accurate quantitative values may be useful to assess anatomical or physiological changes in the lungs in patients with previously treated COVID-19 infection.OBJECTIVE: To test a quantitative semi-automated algorithm for CT imaging in patients with confirmed COVID-19 infection and to compare the results to MR lung perfusion after coronavirus infection.MATERIALS AND METHODS: The data from 100 chest CT scans of patients with COVID-19 were retrospectively analyzed. 3D segmentation of the lungs was carried out with automatic counting of the number of separated pixels in each slice. For quantitative data analysis, classification based on the density value of each pixel according to the Hounsfield scale was used. The obtained data were compared with quantitative parameters of pulmonary MR perfusion in these patients.Statistics. Generalized additive model with beta distribution, Spearman correlation coefficient was used, Benjamini-Yekuteli correction was used to correct obtained p-values. Comparisons were determined as statistically significant when p<0.05. RESULTS: There was a correlation between quantitative CT data (fractions of pixels corresponding to non-ventilated and hypo-ventilated lung tissue) and the distribution of CT data into groups according to an empirical visual scale. We obtained a correlation between the functional perfusion parameters and the CT images: rMTT — 0.35 (p=0.001), rPBF — 0.23 (p=0.038) and rPBV — 0.35 (p=0.001).DISCUSSION: Using the algorithm of quantitative semi-automatic processing of CT-images suggested in this work allows to obtain numerical data, objectively reflecting percentage of affected lung tissue, that is especially relevant for diagnostics of COVID-19 pneumonia. The obtained correlation between functional perfusion parameters and CT picture can be potentially a marker of the lung pathological changes after COVID-19 pneumonia, that requires further investigations.CONCLUSION: Quantitative processing of CT-images allowed to correctly compare the CT scans of lung lesions in COVID-19 with MR lung perfusion data after COVID-19 infection which could potentially be of prognostic value.
Ноты христианской античности в архитектуре православного храма: от романтизма XIX к «постсовременности» XXI века

Published: October 2023

Постановка проблемы критериев современности в архитектуре православного храма представляется ключе­вой в период интенсивного развития храмостроительства. В статье предпринимается попытка раскрыть проблему с позиции внутренней организации сакрального пространства, подчинённого церковной традиции и мало изменяемого во времени. Внимание сосредоточено на примерах концептуального обращения мастерами к истокам христианства, памятникам христиан­ской античности с целью обновления форм церковного искусства. Приводится анализ и сопоставление взглядов художников, мыслителей в истории XIX века и современной России, созданных ими проектов и построек.
Представлены основные положения теории, проекты росписей, иконостасов князя Г.Г. Гагарина, стоявшего у истоков византийского стиля русского искусства 1860-х годов. Предпринята попытка прояснить семантику и художественные принципы недавних архитектурных проектов архимандрита Зинона (Теодора) - известного «ревнителя достоинства иконы». Разби­раются три позиции. Критерии современности в церковном искусстве двух эпох - византийского стиля времени историзма и потенциального искусства будущей «постсовременности». Метод Гагарина и возвращение византийского образца путём адаптации его к языку академического искусства. Метод Зинона, его идеи иконоподобия образа пространства совершения богослужения путём возвращения к становлению и расцвету византийского канона, а отчасти его архаизации в убранстве храма. Предлагается определение стиль «богословия Восточной Церкви» в архитектуре, в противовес иллюстративной ар­тикуляции христианских догматов и евангельского слова в убранстве храма.

Application of a Modification of the Grid-Characteristic Method using Overset Grids for Explicit Interface Description to Modelling the Relief of the Ocean Shelf
Authors: Stetsyuk V. O. 
Published: October 2023

Introduction. The problem of modelling the propagation of elastic waves is of great practical importance when conducting seismic exploration. Based on it, a model of the environment under study is being built. At the same time, the quality of the constructed model is determined by the accuracy of solving the modelling problem, which ensures constantly increasing requirements for modelling accuracy. For accurate modelling, it is important to correctly describe and take into account the boundaries of the media. At the same time, the quality of the constructed model is determined by the accuracy of solving the modelling problem, which ensures constantly increasing requirements for modelling accuracy.Materials and Methods. We have studied a modification of the grid-characteristic method on rectangular grids using overset grids to describe the interface of media of complex shape. This approach has previously been used to describe the earth’s surface when conducting simulations on land. This paper describes its application in modelling the relief of the ocean shelf.Results. The use of the overset grid reduces the modelling error, the number of parasitic waves and artifacts and makes it possible to get a more visual picture.Discussion and Conclusions. Overset grids can be used to describe the interface of media in modelling seismic exploration of the ocean shelf. Their use makes it possible to increase the accuracy of modelling and reduce the number of artifacts compared to using only one grid.

Introduction. Prediction of suspension deposition zones is required to assess and minimize the negative impact on the ecosystem of the reservoir during dredging within the framework of large-scale engineering projects, prediction of suspension deposition zones is required to assess and minimize the negative impact on the ecosystem of the reservoir. It is necessary to build a mathematical model that takes into account many factors that have a significant impact on the accuracy of forecasts. The aim of the work is to construct a mathematical model of transport of multicomponent suspension, taking into account the composition of the soil (different diameter of the suspension particles), the flow velocity of the water flow, the complex geometry of the coastline and bottom, wind stresses and friction on the bottom, turbulent exchange, etc.Materials and Methods. A mathematical model for the transport of a multicomponent suspension and an approximation of the proposed continuous model with the second order of accuracy with respect to the steps of the spatial grid are described, considering the boundary conditions of the Neumann and Robin type. The approximation of the hydrodynamics model is obtained based on splitting schemes by physical processes, which guarantee fulfillment mass conservation for discrete model.Results. The proposed mathematical model formed the basis of the developed software package that allows to simulate the process of sedimentation of a multicomponent suspension. The results of the work of the software package on the model problem of sedimentation of a three-component suspension in the process of soil dumping during dredging are presented.Discussions and Conclusions. The mathematical model of transport of three-component suspension is described and software implemented. The developed software allows to simulate the process of deposition of suspended particles of various diameters on the bottom, and to evaluate its effect on the bottom topography and changes in the bottom composition. The developed software package also allows to analyze the process of sediment movement in the case of resuspension of multicomponent bottom sediments of the reservoir, which causes secondary pollution of the reservoi

The compounds of the argyrodite structure have high conductivity values in the solid state due to the simultaneous coexistence of a "rigid" anionic framework and disordered cationic sublattice. In this regard, argyrodites are considered to be promising superionic materials for use as a working element of solid-state batteries. This work presents the results of the study of the electrophysical parameters of Ag8GeS6 single crystal grown by directional crystallization from the melt technique. It was found by the XRD method that the grown Ag8GeS6 single crystal crystallizes in a low-temperature orthorhombic modification with unit cell parameters: a = 15.147 Å, b = 7.469 Å, c = 10.584 Å. The frequency (10 Hz - 0.3 MHz) and temperature (20 - 110°C) dependence of the electrical conductivity was studied on a single crystal plate of Ag8GeS6 oriented in the (011) plane by impedance spectroscopy. The frequency dependence of the total electrical conductivity of Ag8GeS6 shows an increase in the total electrical conductivity with increasing frequency, which is typical for mixed ionic-electronic conductors. It was determined that the total conductivity of the Ag8GeS6 single crystal is 3.82 × 10-5 S/cm, and the activation energy is 0.728 eV.

Semiconductor binary and ternary argentum selenides are of considerable practical interest, particularly as promising thermoelectric materials. These include Ag2Se, a narrow-band semiconductor, and Ag7PSe6, with a disordered cationic sublattice and a rigid anionic framework that causes efficient phonon scattering. Doping of Ag7PSe6 with the narrow bandgap semiconductor Ag2Se should increase its conductivity and Ag2Se with a more disordered Ag7PSe6 argyrodite phase to a decrease in thermal conductivity. In both cases, this should increase the thermoelectric figure of merit of the respective phases. At the same time, establishing the conditions for obtaining doped phases requires studying the conditions of their existence in the Ag7PSe6-Ag2Se system. Present work studies phase equilibria in the Ag7PSe6-Ag2Se system in the entire concentration range. A corresponding phase diagram was constructed based on the X-ray phase and differential thermal analysis results. It was found that the Ag7PSe6-Ag2Se system is quasi-binary. It is characterized by four processes: two eutectoid processes at 405 K and 433 K, caused by the presence of two polymorphic modifications in Ag2Se and Ag7PSe6, respectively; eutectic process at 893 K (the coordinates of the eutectic point are 893 K and ~8 mol% Ag2Se) and monotectic process at 977 K. Above this temperature, in the concentration range of ~9 - ~87 mol%, a region of immiscibility in the liquid is observed. The homogeneity regions of the initial components are less than 5 mol%.

The search and study of new materials suitable for use in the newest solid-state batteries is an important direction of modern solid-state ionics. Among the potential materials, it is worth mentioning compounds of the argyrodite family. The characteristic feature of these phases is the presence of a disordered cationic sublattice, which provides significant cationic conductivity in the solid state. This work presents the results of studies of the electrical conductivity of a single crystalline sample of ltm-Ag7PS6. The single crystal of Ag7PS6 was grown by the method of directional crystallization from the melt. The crystal was identified by means of XRD method. It was found that the grown Ag7PS6 sample crystallizes in a low-temperature modification in a primitive cubic cell. The frequency (1×101–3×105 Hz) and temperature (25-100°C) dependence of the total electrical conductivity was measured on an oriented and specially prepared ltm-Ag7PS6 single crystalline plate (using gold contacts). The total conductivity of Ag7PS6 single crystals is 6.51×10–7 S/cm (t = 25°C). According to the results of temperature studies of the dependence of the total conductivity, the thermal activation nature of the conductivity was established.

Untargeted metabolomic profiling of dogs with myxomatous mitral valve disease and congestive heart failure shows metabolic differences associated with the presence of cardiac cachexia
Authors: Freeman Lisa M. , Rush John E. , Karlin Emily T. 
Published: October 2023

Abstract

OBJECTIVE
To determine the effects of cardiac cachexia on the metabolomic profile in dogs with myxomatous mitral valve disease (MMVD).

ANIMALS
3 groups of dogs with MMVD enrolled between November 30, 2018, and April 7, 2022: (1) Dogs with congestive heart failure (CHF) and cachexia (CHF-cachexia group; n = 10); (2) dogs with CHF that had no cachexia (CHF-no cachexia group; n = 10); and (3) dogs with asymptomatic disease (American College of Veterinary Internal Medicine [ACVIM] Stage B2) with no cachexia (B2 group; n = 10).

METHODS
Metabolomic profiles were analyzed from serum samples using ultra-high-performance liquid chromatography-tandem mass spectroscopy. Dogs in the 3 groups were compared, with statistical significance defined as P < .05 with a low false discovery rate (q < .10) and nominal statistical significance defined as P < .05 but q > .10.

RESULTS
Numerous metabolites were significantly (n = 201) or nominally significantly (n = 345) different between groups. For example, when comparing the CHF-cachexia vs CHF-no cachexia groups, lipids were the predominant metabolite differences, including many medium- and long-chain dicarboxylates and dicarboxylate acylcarnitines. For comparisons of the CHF-cachexia vs B2 groups and the CHF-no cachexia vs B2 groups, amino acids, nucleotides, and cofactors/vitamins were the predominant metabolite differences.

CLINICAL RELEVANCE
Some significant metabolite differences were identified between dogs with and without cardiac cachexia.
Oh What Tangled Webs We Weave—Unpacking (and Unpicking) the Majority Opinion in Dobbs, State Health Officer of the Mississippi Department of Health et al. v. Jackson Women's Health Organization et al.
Authors: Loveland Ian 
Published: October 2023

Abstract
This paper evaluates the majority judgment in the United States Supreme Court in Dobbs v. Jackson Women's Health Organization. It is suggested that much of what is said in the majority opinion ostensibly appears eminently defensible if viewed solely from a narrowly legalistic perspective. But closer analysis suggests that the majority's reasoning has some weaknesses when viewed within that limited paradigm. A further line of inquiry assesses whether adopting such a ‘legalistic’ approach to the question of abortion rights is in any event an appropriate position for the Court to adopt. The final section of the paper explores two additional contextual issues: the first relates to the personal ethical integrity of some of the majority judges; the second to the adequacy of State political processes as a means to address the abortion rights controversy.
From Crown Privilege to State Secrets1
Authors: Weaver William G. , Fisher Louis 
Published: October 2023

Abstract
The state secrets privilege is the most formidable evidentiary privilege available to the United States government. Available only to the executive branch, it is used to protect national security information from disclosure during litigation, and is habitually acquiesced to by courts. Once invoked, the privilege prevents covered material from being put into evidence that touches sensitive matters of national security. It is apparent that this privilege is subject to abuse by the executive branch to shield activities and personnel from judicial scrutiny and legal inquiries for reasons other than to protect national security. The privilege derives from British and Scottish doctrines of Crown Privilege that allow government to withhold evidence from legal proceedings to protect the public interest. The derivation of the state secrets privilege from the tradition of Crown Privilege has never been thoroughly explored. This article traces the influence of Crown Privilege in the development and evolution of the state secrets doctrine in the United States.
Analysis of Labor Market Transformation in the Context of Industry 4.0
Authors: Stryzhak Olena 
Published: October 2023

Abstract
The digitalization of the economy and society in the context of Industry 4.0 affects the labor market. New jobs are being created with new personnel requirements. At the same time, digitalization processes affect countries and sectors of the economy in different ways. The number of employed is declining in some sectors and increasing in others. The ratio of people employed in different industries also differs from country to country. As the digitalization of production relations intensifies, transformation processes in the labor market will increase. In the context of the actualization of digital changes in modern society, the aim of the article is to analyze the labor market under the digitalization of economic relations. The World Development Indicators (WDI) and Digital Intelligence Index (DII) were used to realize the purpose of the study. The study covers 89 countries for 2019. Correlation analysis, standardization, cluster analysis and analysis of variance were used as methods in the research. As a result of the study, the following conclusions were obtained. A strong relationship was found between Gross Domestic Product (GDP) and DII for the whole sample. The cluster analysis process found that the variables form three clusters with values of most indicators by group: at the high, the average and the low levels. Plots of mean and confidence intervals for the variables in each cluster were also plotted. Correlation coefficients were calculated for each cluster. It was found that each group has its own internal patterns.
