Stability for the electromagnetic inverse source problem in inhomogeneous media
Authors: Zhao Yue 
Published: May 2022

Abstract
This paper is concerned with the stability of the inverse source problem for Maxwell’s equations in an inhomogeneous background medium. We show that the stability estimate consists of the Lipschitz-type data discrepancy and the high frequency tail of the source function, where the latter decreases as the upper bound of the frequency increases. The analysis employs scattering theory to obtain the holomorphic domain and an upper bound for the resolvent of the elliptic operator.
Direct and inverse problems for time-fractional heat equation generated by Dunkl operator
Authors: Bekbolat Bayan , Serikbaev Daurenbek , Tokmagambetov Niyaz 
Published: May 2022

Abstract
In this paper, we study non–local in time evolution type equations generated by the Dunkl operator. Direct and inverse problems are investigated with the Caputo time-fractional heat equation with the parameter

γ
≤

{0<\gamma\leq 1}

. In particular, well-posedness properties are established for the forward problem. To adopt techniques of the harmonic analysis, we solve the problems in the Sobolev type spaces associated with the Dunkl operator. Our special interest is an inverse source problem for the Caputo–Dunkl heat equation. As additional data, the final time measurement is taken. Since our inverse source problem is ill-posed, we also show the stability result. Moreover, as an advantage of our calculus used here, we derive explicit formulas for the solutions of the direct and inverse problems.
Randomized Monte Carlo algorithms for matrix iterations and solving large systems of linear equations
Authors: Sabelfeld Karl K. 
Published: May 2022

Abstract
Randomized scalable vector algorithms for calculation of
matrix iterations and solving extremely large linear algebraic equations
are developed. Among applications presented in this paper are randomized
iterative methods for large linear systems of algebraic equations governed by M-matrices.
The crucial idea of the randomized method
is that the iterations are performed by sampling random columns only, thus avoiding not only matrix-matrix but also matrix-vector multiplications. The suggested vector randomized methods are highly efficient for solving linear equations of
high dimension, the computational cost depends only linearly on the dimension.
Ein Stück Heimat? Hans Mayers ambivalente Sicht auf Israel
Authors: Hermes Stefan 
Published: May 2022

Abstract
Hans Mayer (1907–2001), one of the most eminent literary critics and public intellectuals in post-war Germany, visited Israel four times between 1968 and 1995. This article aims to reconstruct the key elements of Mayer’s ambivalent (albeit mainly positive) perception of Israeli society and culture as it is documented in his travelogue Reisen nach Jerusalem from 1997 and several further texts. However, Mayer’s view on Israel can only be understood adequately by also considering his situation as a non-religious Jew and Shoah survivor in Germany.
Multiple rogue wave solutions of a generalized (3+1)-dimensional variable-coefficient Kadomtsev--Petviashvili equation
Authors: Li Kun-Qiong 
Published: May 2022

Abstract
Kadomtsev–Petviashvili equation is used for describing the long water wave and small amplitude surface wave with weak nonlinearity, weak dispersion, and weak perturbation in fluid mechanics. Based on the modified symbolic computation approach, the multiple rogue wave solutions of a generalized (3+1)-dimensional variable-coefficient Kadomtsev–Petviashvili equation are investigated. When the variable coefficient selects different functions, the dynamic properties of the derived solutions are displayed and analyzed by different three-dimensional graphics and contour graphics.
Fabrication, characterization, and performance of poly (aryl ether nitrile) flat sheet ultrafiltration membranes with polyvinyl pyrrolidone as additives
Authors: Lu Zhaohui 
Published: May 2022

Abstract
Poly(aryl ether nitrile) (PEN) was used to fabricate ultrafiltration membrane via immersion precipitation phase inversion method. The effects of polyvinyl pyrrolidone (PVP) of different molecular weights and concentrations on the structure and performance of PEN membranes were investigated. The membranes were observed by scanning electron microscope, atomic force microscope, equilibrium water content (EWC), porosity (ε), and so on. The membranes were subjected to ultrafiltration characterizations such as pure water flux (PWF), compaction factor (CF), hydraulic permeability (P
m), and bovine serum albumin (BSA) rejection rate. The hydrophilicity was characterized by infrared spectroscopy and contact angle tests. Results showed that molecular weight of PVP had significant effect on PEN membrane formation, which the membrane prepared by PVP-k30 exhibited excellent comprehensive performance. Meanwhile, the concentration of PVP-k30 could effectively control the select-permeability of PEN membrane. With PVP-k30 concentration increased from 7 to 13 wt%, the prepared PEN membranes got higher EWC, ε, CF, and P
m. The PWF increased from 146.5 to 249.1 L m−2 h−1 bar−1, while the overall rejection of BSA remained above 90%. Further increasing the addition amount to 16 wt%, the membrane performance began to decline. Finally, the addition of PVP-k30 could effectively improve the hydrophilicity of prepared PEN membrane surface.

Published: May 2022

Abstract
In this paper, we are concerned with an optimal control problem where the
system is driven by a G-stochastic differential equation, where an admissible
set of controls is convex. We establish necessary as well as sufficient
optimality conditions for this model. At the end of this work, we illustrate
our main result by giving an example that deals with the linear-quadratic problem.

Authors: Seitz Bianca , Maas Gerhard 
Published: May 2022

Abstract
4-CF3-pyrido[1,2-a]pyrimidin-5-ium triflates could be prepared in fair to high yields from acetylenic iminium salts R-C≡C–C(CF3)=N+Me2·CF3SO3
− and 2-aminopyridinium triflate under thermal conditions. Their reactions with protic heteronucleophiles, leading to 4-CF3, 4-XR-substituted 1,4-dihydropyrido[1,2-a]pyrimidin-5-ium salts, have been studied and reversible addition as well as subsequent opening of the pyrimidine ring have been observed. The cyclocondensation of a 3-phenyl-propyniminium triflate and 3-aminoyridinium triflate required strong thermal activation and yielded a 4-CF3-and a 4-CF3,5-CH3-[1,7]naphthyridine. A 1-CF3-benzo[f][1,7]naphthyridine was obtained from the same propyniminium salt and 3-aminoquinolinium triflate.

La fórmula ejecutiva subnacional y el rol de la Vicegobernación en Argentina. Estudio de los casos provinciales de Neuquén, Río Negro y Chubut (2015-2018)
Authors: Pesquero Bordón Jimena 
Published: May 2022

El objetivo del presente trabajo es caracterizar la Vicegobernación y su rol en la fórmula ejecutiva subnacional en Argentina de forma comparada y a través del estudio de casos. Se consideran las herramientas analíticas desarrolladas para el estudio de la fórmula presidencial y el papel de la institución Vicepresidencial, extrapoladas al abordaje de instituciones análogas a nivel provincial. Se identifican tendencias respecto del impacto de los factores normativos y políticos de la figura Vicegubernamental en los contextos electoral y de gobierno y se presta atención en el proceso de sucesión. Más allá de la potencialidad política del Vicegobernador conferida por su rol institucional de reemplazo, la relevancia de la Vicegobernación se pone en evidencia en el plano político, específicamente en su relación con la Gobernación, como una esfera central para sellar coaliciones cuando el acuerdo político entre facciones es lábil. Finalmente, se aspira a que las conclusiones del presente trabajo contribuyan a cubrir un vacío en la literatura existente.

ENTRE A EUROPA E A AMAZÓNIA: DO RITUAL DA ARTE DO PODER AO PODER DA ARTE DO RITUAL
Authors: Mourão Rui 
Published: May 2022

Nas pós-modernas sociedades ocidentais é possível encontrar uma correspondência entre a estrutura de poder do seu sistema das artes e a alargada macroestrutura em que se insere. A macroestrutura tem como força motriz o que o antropólogo Viveiros de Castro identificou como “Santíssima Trindade do Pai-Estado, do Filho-Mercado e do Espírito Santo da Razão”1, expressão usada provocadoramente para fazer corresponder a ontologia do moderno sistema de crenças ocidental com a antiga matriz ontológica cristã. A ontologia ocidental provém em parte da ontologia cristã, mas é já outra coisa. Mantém a forma da estrutura (onde a Verdade é uma, numa lógica monoteísta, que por sua vez se constitui de uma trindade de forças), porém no ideal moderno substitui-se os seus elementos-chave por outros atualizados pela nova realidade dessacralizada. Com essa identificação, Viveiros de Castro reverbera a tipificação do tradicional modelo cristão de “santíssima trindade”, reformulado com a atualização da posterior lógica secular nascida na Europa da Modernidade. A qual passou a ser constituída por três forças centrais: os sistemas políticos e públicos do estado, o capitalismo expandido a todo o mundo após os processos colonizadores e os ideais da razão como motor de progresso científico-civilizacional.

Objective. The aim of this study was to assess the association between the level of blood pressure (BP) and the prevalence of coronary heart disease (CHD) in women of working age in an open population of a moderately urbanized Siberian city (on the model of Tyumen).Design and methods. We included 1000 women of an open urban population aged 25–64 years, 250 people in each of four decades of life (among persons 25–34, 35–44, 45–54, 55–-64 years old), selected by the method of a random representative sample from the electoral lists of the administrative district of Tyumen, the response was 70,3% (703 participants). In all subjects we measured BP; assessed the presence of coronary artery disease — according to standardized epidemiological methods: based on the extended criteria, “definite” CHD (strict criteria) and “possible” CHD (non-strict criteria) were distinguished. Statistical analysis was performed using STATISTICA 12.0 software, the differences were considered significant at p-level ≤ 0,005.Results. Almost every third woman (25–64 years old) had increased BP (34,7 %), the frequency of increased BP grows with age, reaching 63,3 % in the older group. Low awareness of high BP and low adherence to treatment were found. There was a correlation between the prevalence of CHD and BP level and age. In the presence of increased systolic BP, the chance of developing CHD in women aged 25–64 years in the open population increases by 1,9–2,7 times (p < 0,05), in the presence of increased diastolic BP, the chance of developing CHD according to extended criteria increases by 2,1 times (odds ratio = 2,08, 95 % confidence interval (1,15; 3,74)).Conclusions. Our results can be used for improving the strategy of primary cardiovascular prevention in preventive programs of the Western Siberia region.
