Authors: McHugh Daryl C. , Gershteyn Anna , Boerman Christine , Holloway Robert G. , Roberts Debra E. , George Benjamin P. 
Published: April 2023

Objectives
Patients with severe intracerebral hemorrhage (ICH) often suffer from impaired capacity and rely on surrogates for decision-making. Restrictions on visitors within healthcare facilities during the pandemic may have impacted care and disposition for patient with ICH. We investigated outcomes of ICH patients during the COVID-19 pandemic compared to a pre-pandemic period.

Materials and methods
We conducted a retrospective review of ICH patients from two sources: (1) University of Rochester Get With the Guidelines database and (2) the California State Inpatient Database (SID). Patients were divided into 2019–2020 pre-pandemic and 2020 pandemic groups. We compared mortality, discharge, and comfort care/hospice. Using single-center data, we compared 30-day readmissions and follow-up functional status.

Results
The single-center cohort included 230 patients (n = 122 pre-pandemic, n = 108 pandemic group), and the California SID included 17,534 patients (n = 10,537 pre-pandemic, n = 6,997 pandemic group). Inpatient mortality was no different before or during the pandemic in either cohort. Length of stay was unchanged. During the pandemic, more patients were discharged to hospice in the California SID (8.4% vs. 5.9%, p<0.001). Use of comfort care was similar before and during the pandemic in the single center data. Survivors in both datasets were more likely to be discharged home vs. facility during the pandemic. Thirty-day readmissions and follow-up functional status in the single-center cohort were similar between groups.

Conclusions
Using a large database, we identified more ICH patients discharged to hospice during the COVID-19 pandemic and, among survivors, more patients were discharged home rather than healthcare facility discharge during the pandemic.

Published: April 2023

Aim
In a retrospective and exploratory case-control study, we examined the genetic association of two common polymorphisms in the 3’ untranslated region (UTR) of DICER1 (rs3742330) and DROSHA (rs10719) genes in primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG), and its related clinical phenotypes in a Saudi cohort.

Methods
DNA genotyping was performed using TaqMan real-time PCR assays in 500 participants, including 152 POAG, 102 PACG, and 246 non-glaucomatous controls. Statistical analyses were performed to examine the association(s).

Results
Allele and genotype frequency of rs3742330 and rs10719 did not vary significantly in POAG and PACG compared to controls. No significant deviation was observed from Hardy-Weinberg Equilibrium (p > 0.05). Gender stratification revealed no significant allelic/genotype association with glaucoma types. Also, these polymorphisms showed no significant genotype effect on clinical markers such as intraocular pressure, cup/disc ratio, and the number of antiglaucoma medications. Logistic regression showed no effect of age, sex, rs3742330, and rs10719 genotypes on the risk of disease outcome. We also examined a combined allelic effect of rs3742330 (A>G) and rs10719 (A>G). However, none of the allelic combinations significantly affected POAG and PACG.

Conclusions
The 3’ UTR polymorphisms rs3742330 and rs10719 of DICER1 and DROSHA genes are not associated with POAG and PACG or its related glaucoma indices in this Middle-Eastern cohort of Saudi Arab ethnicity. However, there is a need to validate the results on a broader population and other ethnicities.

Published: April 2023

O manguezal é um ecossistema de transição entre os ambientes terrestre e marinho e representa um importante indicador ecológico pelos serviços ecossistêmicos fornecidos. No entanto, apesar da relevância ecológica, ainda sofre pressões antrópicas e vem perdendo em extensão e qualidade ambiental. No Brasil e, especificamente, no município de Paranaguá, uma mescla de uso antrópico tem causado pressões significativas sobre os manguezais. Neste sentido, o objetivo deste estudo é avaliar o grau de antropização dos manguezais urbanos do município de Paranaguá (PR), através da utilização de imagens de altíssima resolução espacial, obtidas através de Aeronave Remotamente Pilotada a fim de subsidiar políticas municipais de ordenamento territorial. Do ponto de vista metodológico, a partir de campanhas de campo, foram produzidos mapas com auxílio do software QGIS 3.10, a partir da fotointerpretação de ortomosaicos . A legenda das classes de antropização abrangeu: deposição de lixo domiciliar (i), entulhos (ii), lançamento de efluentes domésticos sem tratamento (iii) e manilhas (iv). Os resultados apontaram um total de 475 pontos de pressão antrópica sobre as 22 manchas de manguezal analisadas. A classe de maior destaque foi a de lixo domiciliar, seguida respectivamente de lançamento de efluentes domésticos sem tratamento, entulhos (material de construção) e, por fim, manilha. Como conclusão, o uso de ortomosaicos de alta resolução mostrou ser uma ferramenta importante e eficaz na análise da antropização dos manguezais urbanos, destacando assim , as áreas com maior pressão e, contribuindo para um monitoramento contínuo. Os produtos desta pesquisa podem auxiliar na elaboração de de instrumentos de ordenamento territorial do município, destacando a necessidade da construção de um olhar holístico em prol da conservação dos manguezais.

Assessing the Impact of the Implementation of Universal Basic Income on Entrepreneurship
Authors: Aceytuno-Pérez María-Teresa , de Paz-Báñez Manuela A. , Sanchez-López Celia 
Published: April 2023

Abstract
We focus on the literature about UBI and the experiments developed all around the world to test it in order to address how UBI implementation could affect entrepreneurship. Building on these findings and various strands of entrepreneurial theory, we develop a theoretical framework to explain how the implementation of UBI would dramatically change the environment of entrepreneurial activity, shaping entrepreneurial action at three levels: (i) the desirability of becoming an entrepreneur; (ii) the perceived feasibility of becoming an entrepreneur; (iii) the propensity to act. Consequently, UBI implementation would arguably facilitate the decision to become an entrepreneur. The contribution of the paper is threefold. It firstly provides a theoretical framework that opens new directions for further research on the relationship between UBI and entrepreneurship. Secondly, it offers new insights for policy makers by shedding light on potential effects of UBI implementation. Finally, it raises further questions that remains unsolved related to the role of non-pecuniary motivations and financial constraints.

Concepts of phenomenological irreversible quantum thermodynamics II: time dependent statistical ensembles of bipartite systems
Authors: Muschik Wolfgang 
Published: April 2023

Abstract
The wide-spread opinion is that original quantum mechanics is a reversible theory, but this statement is only true for undecomposed systems that are those systems for which sub-systems are out of consideration. Taking sub-systems into account, as it is by definition necessary for decomposed systems, the interaction Hamiltonians –which are absent in undecomposed systems– can be a source of irreversibility in decomposed systems. Thus, the following two-stage task arises: How to modify von Neumann’s equation of undecomposed systems so that irreversibility appears, and how this modification affects decomposed systems? The first step was already done in Muschik (“Concepts of phenomenological irreversible quantum thermodynamics: closed undecomposed Schottky systems in semi-classical description,” J. Non-Equilibrium Thermodyn., vol. 44, pp. 1–13, 2019) and is repeated below, whereas the second step to formulate a quantum thermodynamics of decomposed systems is performed here by modifying the von Neumann equations of the sub-systems by a procedure wich is similar to that of Lindblad’s equation (G. Lindblad, “On the generators of quantum dynamical semigroups,” Commun. Math. Phys., vol. 48, p. 119130, 1976), but different because the sub-systems interact with one another through partitions.
Dynamic fracture behavior of SA508-3 steel for nuclear power equipment under medium-and low-loading rates
Authors: Yao Di , Li Yilei , Jiang Xiaosong , Luo Jiacheng , Yu Li , Tang Peng , Luo Juan 
Published: April 2023

Abstract
The heat treatment of SA508-3 steel was carried out by means of quenching and manual aging. The microstructure and mechanical properties of the prepared SA508-3 steel were analyzed and tested. The results show that the main composition of the matrix of SA508-3 steel is bainite, and the main composition of the second phase is alloy cementite containing Fe, Mn and C. The second phase is distributed at both the matrix and grain boundaries. The second phase can prevent the dislocation from moving by fixing the dislocation, and the second phase at the grain boundary can strengthen the matrix by hindering the grain boundary movement. The stress-strain curves of SA508-3 steel under different loading rates show that when the strain rate is greater than 0.5 m s−1, the fracture mode of the steel is brittle fracture, and when the strain rate is less than 0.5 m s−1, the fracture mode of the steel is ductile-brittle bonding fracture. The second phase of the crack first diffuses to the grain boundary, reducing the strength of the grain boundary. When the loading rate is high, the second phase at the grain boundary cannot diffuse in time, and the material undergoes transgranular fracture and intergranular fracture.

Abstract
The welding parameters optimization of TC4 titanium alloys/304 stainless steel (TC4/304 SS) by friction stir lap welding (FSLW) based on orthogonal test was researched. The results show that when the rotating speed was constant, the area of the high temperature zone and the peak temperature decreased with the increase of the traversing speed; when the traversing speed was constant, the area of the high temperature zone and the peak temperature increased with the increasing rotating speed. Among them, under the condition of low heat input, the interface temperature was about 912 °C, the material at the interface cannot fully react, and there was no formation of a large amount of brittle and hard intermetallic compounds; under the condition of medium heat input, the interface temperature was about 930 °C, this temperature caused a large amount of brittle and hard intermetallic compounds at the interface; under high heat input, the interface temperature was about 975 °C, a large number of intermetallic compounds were not formed at the interface.

Symmetry analysis of the constant acceleration curve equation
Authors: Pakdemirli Mehmet 
Published: April 2023

Abstract
Lie group theory is applied to the curve equation which maintains constant normal accelerations for a vehicle with constant deceleration. The curve equation is a third order nonlinear ordinary differential equation for which the symmetries are calculated. It is shown that the equation possesses four-parameter Lie group of transformations including scaling, rotation and translational symmetries. In the case of constant velocity, the algebra increases to a six-parameter Lie group of transformations. Using the symmetries of the differential equation, the group invariant solutions are determined first. The conditions for group invariant solutions to exist are given. By employment of the symmetries, a solution is obtained by reduction of order also. It is found that the nontrivial solutions are of implicit complex forms.

Abstract
Poulos, N, Haff, GG, Nibali, M, Norris, D, and Newton, R. Influence of complex training design on acute postactivation performance enhancement of jump squat and ballistic bench throw performance in developing team-sport athletes. J Strength Cond Res 37(5): 969–979, 2023—The effect of complex training (CT) session design on acute postactivation performance enhancement (PAPE) of loaded jump squat(s) (JS) and ballistic bench throw(s) (BBT) was examined. This study further investigated whether relative strength is a moderating factor in PAPE in response to 3 distinct CT protocols. Fourteen Australian Football League (AFL) Academy athletes performed 3 different protocols comprising 85% 1 repetition maximum (1RM) back squats and bench press, and 30% 1RM loaded JS and BBT, differing in the sequencing of exercise order (i.e., complex pairs performed in isolation or with additional exercise interspersed within the intracomplex recovery period) and duration of the intracomplex recovery (2.5, 5, or 15 minutes). Differences in JS and BBT performance between CT protocols were trivial except for JS eccentric depth and eccentric impulse where small to moderate substantial differences were observed between protocols 2 and 3 in various sets; a small difference was observed between protocols 1 and 3 for eccentric depth. Small differences between protocols 1 and 2 were observed in set 1 in BBT peak velocity (ES = −0.26) and peak power (W·kg−1) (ES = −0.31). Small magnitudes of PAPE and decrements in performance were observed in some variables within protocols, yet effects across sets were inconsistent. Relative strength was negatively associated with JS performance (i.e., stronger athletes demonstrated a lower magnitude of PAPE) yet positively associated with PAPE of BBT peak force (N·kg−1) and peak power (W·kg−1). Alternating lower-body and upper-body complex sets and performance of ancillary exercise within the intracomplex recovery does not contribute to cumulative fatigue throughout the session and does not detrimentally affect subsequent JS and BBT performance. The manipulation of complex-set sequences offers practitioners a time-efficient means of providing both lower-body and upper-body heavy-resistance and ballistic training stimuli to achieve chronic training adaptations in maximal strength and power, with targeted improvements in specific kinetic and kinematic variables.

Published: April 2023

A fase do desenvolvimento da juventude tem como marcadores a formação da identidade, desenvolvimento de autonomia e responsabilidade, bem como a experimentação sexual. Assim, tem-se como objetivo avaliar dados preliminares acerca da não utilização de preservativos em jovens de 18 a 24 anos, ambientados no contexto da pandemia de COVID-19. A definição adotada para identificar comportamentos sexuais menos protegidos foi de pelo menos uma relação sem o uso de preservativo, entre as últimas três relações sexuais, levando em consideração as ações de prevenção combinada. Para a presente pesquisa, foi conduzido um estudo transversal através de um questionário online auto aplicado disponível no Google Forms, divulgado em plataformas virtuais e redes sociais. A aplicação do questionário foi precedida pelo preenchimento do Termo de Consentimento Livre e Esclarecido (TCLE). Os dados referentes às variáveis foram submetidos a uma análise bivariada no software STATA 15.0. No total, foram entrevistados 472 jovens de 18 a 24 anos. Dos entrevistados, 72,9% eram do sexo feminino, 30,5% tinham de 21 a 22 anos, 73,3% pertencia a classe econômica A e 79,9% se auto declararam brancos. Acerca do não uso de preservativos, 40,7% dos jovens tiveram este comportamento durante o período de pandemia de COVID-19. Estiveram associados ao comportamento sexual menos protegido o sexo feminino (p=0,032), a orientação sexual heterossexual (p=0,001) e estar em um relacionamento estável (0,008). É imprescindível que as ações dos serviços de saúde invistam em intervenções voltadas à educação para a saúde com a população de jovens, para aumentar a distribuição de preservativos e o acesso à informação.

Выявление планировочной специфики столицы в материалах концепции перспективного развития Москвы 1986 года А. Э. Гутнова
Authors: Гостев Максимилиан 
Published: April 2023

Статья посвящена особенностям планировочной структуры российской столицы, представленной в материалах Концепции перспективного развития Москвы и Московской области. Этот проект был разработан в Институте Генплана Москвы под руководством А. Э. Гутнова и предшествовал неутвержденному генплану 1989 года. Концепция оказалась забыта после перестройки, но в своем методологическом обеспечении успела осуществить принципиальный переход от «нормативного» города к «эволюционному» и фактически открыла дорогу системе градостроительного регулирования, вошедшей в состав генерального плана Москвы 1999 года. В материалах Концепции была апробирована гипотеза о том, что структурно-планировочная специфика города в наибольшей степени проявляется под действием механизмов его самоорганизации. В формализованном виде эти механизмы выражены в терминах каркасно-тканевой модели города. В статье обсуждаются методические основания выстраивания планировочной структуры города в Концепции. Они анализируются с точки зрения выявления предпосылок формирования проектных решений, которые обеспечивают эволюционный характер развития города. Также раскрывается роль моделирования градостроительных систем с использованием ЭВМ в формировании плана перспективной пространственной структуры Москвы.
Problematyka niezdolności konsensualnej do zwarcia małżeństwa w pracach Papieskiej Komisji do Rewizji KPK w fazie konsultacji (1975-1978) oraz ponownego rozpatrzenia projektu nowych kanonów (1978-1980)
Authors: Góralski Wojciech 
Published: April 2023

Rozpoczęta po zakończeniu Soboru Watykańskiego II reforma prawa kanonicznego objęła m.in. prawo małżeńskie. Najistotniejszym obszarem kodyfikacji w tym zakresie była zgoda małżeńska, która jest przyczyną małżeństwa. W szczególności chodziło o skodyfikowanie normy o niezdolności konsensualnej wywodzącej się z prawa naturalnego. Po pierwszym etapie prac kodyfikacyjnych prowadzonych przez Papieską Komisję ds. Rewizji KPK (przy pomocy Zespołu konsultorów De matrimonio) kontynuowano prace kodyfikacyjne w kolejnych etapach: konsultacje opracowanych projektów z konsultantami (1975-1978), a następnie ponowne rozpatrzenie tych projektów przez Komisję Papieską i jej konsultorów (1980-1981). W wyniku tych prac kan. 1095, nn. 1-3, został zatwierdzony w 1983 r. przez Jana Pawła II.
