Minority Stress and Relationship Satisfaction Among Gay and Bisexual Men
Authors: Shepler Dustin K. , Glaros Mackenzie R. , Boot Jared W.
Published: October 2021

For gay and bisexual men, relationship status and relationship satisfaction have been linked to longevity, positive mental health, and life satisfaction. Factors that contribute to relationship satisfaction among gay and bisexual men were examined within the framework of Meyer’s (2003) minority stress model. Ninety-three gay, bisexual, and pansexual men who ranged in age from 18 to 60 years old (M = 32.14, SD = 10.01) were recruited in person and through Amazon Mechanical Turk to complete measures related to minority identity processes, identity characteristics, and relationship satisfaction. Most men were White (80.6%) with a high education level (58% had completed at least a bachelor’s degree). Multiple linear regression results were significant and indicated that 4 variables (identity concealment, uncertainty, centrality, and affirmation) explained about 40% of the variance in relationship satisfaction, F(6, 86) = 9.42, p ≤ .001 Findings suggest that Meyer’s model can be extended from explaining mental health to understanding relationship satisfaction. Results also draw attention to the role of identity affirmation and identity centrality, a somewhat unique contribution to this area of inquiry.
The Indirect Effect of Worry on Daytime Sleepiness Among College Students
Authors: Hatcher Alexis , Sutton Tiphanie G. , Judah Matt R.
Published: October 2021

Daytime sleepiness is a prevalent problem among college students that is associated with impairment in academic functioning and mental health risk. Sleep disturbances, such as difficulty falling and staying asleep, are associated with daytime sleepiness. Sleep disturbances are predicted by worry and may serve as mechanisms by which worry conveys risk for daytime sleepiness. The present study examined the indirect effect of worry on daytime sleepiness through difficulty falling asleep and difficulty staying asleep in a cross-sectional undergraduate sample (N = 172). An indirect effect of worry on daytime sleepiness was observed through difficulty staying asleep, ab = .02, 95% CI [.001 .04]. There was no indirect effect through difficulty falling asleep, ab = −.01, 95% CI [−.03, .01]. The study contributed to the understanding of how worry is associated with daytime sleepiness among college students. Additional research using longitudinal and experimental design is needed to further test difficulty staying asleep as a mechanism between worry and sleepiness.
Spanning the American West

North American bridge design is dominated by a culture of risk aversion and economic constraint. While objectives of safety and efficiency should be the baseline of any project, they are sometimes set as the sole benchmarks for a successful bridge design within the North American context. When the end game is to simply meet the baseline of safety and efficiency, goals related to user experience and aesthetic impacts are often considered superfluous. This paper showcases lessons learned from designing within this context.

Stories from bridge designs showcase the ups and downs of bootstrapping higher design goals into footbridge projects in the Wild West.

FRUGALITY OF SENTENCE IN KAPITA SELEKTA TITLE DUTY ARTICLES WITH PORTFOLIO MODELÂ Abstract Â Â Â Â Â Â Â Â Â Â Â  The Kapita Selekta course is a course that is intended for fifth semester students (five). The course is a very complex subject because the content and essence of the course discusses all in Indonesian. The purpose of this study is to describe the pattern of making semi-scientific article titles in the Indonesian language course and to describe the economics of making titles in semi-scientific articles on Kapita Selekta courses in the 5th semester of the Indonesian Education Study Program at the Pancasakti University in Tegal. Based on the analysis carried out there are results that have been presented, namely the element of economics which includes four aspects which can be seen from the percentage that has been calculated. Aspect of misinformation 40%, superordinate hypernim 32%, plural words 24% and repetition of subjects 4%. It is seen that those who occupy the element of non-health in the title of semi-scientific articles in the Indonesian selective course, namely aspects of the use of synonyms, occur because the author wants to emphasize the idea that the titles written or chosen can attract readers, but because synonymy and diction are lacking accordingly it should be avoided, for the good of the reader in understanding the reading title.Â Keywords: Frugality, Kapita Selekta, IndonesianÂ

Volpi: Doxa, permanência e denegação na crítica de arte brasileira
Authors: Pedro Magalhães Rosa Marcos
Published: October 2021

Este artigo é uma genealogia da crítica que consagrou Alfredo Volpi. O foco da análise recai sobre a década de 1940, quando Mário de Andrade estabeleceu as principais diretrizes para pensar a “Família Artística Paulista”. Nesse momento, eclipsou-se a nacionalidade italiana do artista, bem como as referências estrangeiras em sua pintura. Surgiu então a mitologia do pintor como operário e artesão, que permanece ativa ainda na contemporaneidade.

Contiguous squamous proliferations in syringocystadenoma papilliferum: A retrospective study of 14 cases
Authors: Aggarwal Divya , Chatterjee Debajyoti , Keshavamurthy Vinay , Chhikara Komal , Saikia Uma Nahar , Radotra Bishan D. , De Dipankar , Singh Mini P.
Published: October 2021

Background:

Syringocystadenoma papilliferum is a benign adnexal neoplasm. Contiguous squamous proliferation has been rarely described in syringocystadenoma papilliferum.

Aims:

This study aimed to evaluate the spectrum and pathogenesis of contiguous squamous proliferation in syringocystadenoma papilliferum.

Materials and Methods:

All cases of syringocystadenoma papilliferum diagnosed over the past 12 years were screened for contiguous squamous proliferation. Cases with associated nevus sebaceous were excluded from the study. Immunohistochemistry for GATA3, CK7, BRAFV600E and p16 was performed. PCR for human papilloma virus, type 16 and 18, was carried out.

Results:

Of a total of 30 cases, 14 cases showed associated contiguous squamous proliferation which included four cases of verrucous hyperplasia, six cases with papillomatosis, two cases with mild squamous hyperplasia and one case each of Bowen’s disease and squamous cell carcinoma. In the cases with non-neoplastic contiguous squamous proliferations, the squamous component did not express CK7 or GATA3. However, the squamous component of premalignant and malignant lesions expressed CK7 and GATA3 concordant with the adenomatous component. BRAF was positive in adenomatous component in five cases while the contiguous squamous proliferation component was negative for BRAF in all but one case. p16 was negative in both components of all cases and PCR for human papilloma virus was negative in all cases.

Limitations:

Due to the rarity of disease, the sample size of our study was relatively small with two cases in the 2nd group, that is, syringocystadenoma papilliferum with malignant contiguous squamous proliferation. Detailed molecular studies such as gene sequencing were not performed.

Conclusion:

Syringocystadenoma papilliferum with contiguous squamous proliferation is underreported, and most commonly displays verrucous hyperplasia. The premalignant and malignant contiguous squamous proliferations likely arise from syringocystadenoma papilliferum while the hyperplastic contiguous squamous proliferations likely arise from the adjacent epidermis. Relationship with high-risk human papilloma virus is unlikely. However, further molecular analysis of larger number of cases is required to establish the pathogenesis.

Development of software based on NX Open for assessing the reliability of REA designs
Authors: Пименов С.А. , Зорков П.П.
Published: October 2021

Рассматриваются основные алгоритмы и численные методы решения задач оценки надежности конструкций радиоэлектронной аппаратуры. Алгоритмы реализованы в виде расчетного программного обеспечения АРКОН для проведения оценки надежности конструкций в условиях случайного нагружения с применением численных методов: метода конечных элементов и метода статистического моделирования.

The paper deals with the development of new software which allows us to use probabilistic methods for evaluating the reliability of CEA designs. The main algorithms and numerical methods for solving problems of reliability assessment of REA structures are considered. The reason for conducting the study was the presence of the lag in development of the program-technical complexes aimed at assessment of the strength reliability in relation to the tasks being solved.

At the moment, analytical methods for estimating the probability of failure-free operation have been developed. Their implementation requires the existence of a law for the distribution of random load parameters and the system itself. This method is deprived of the method of statistical modelling with the calculation of stresses using the finite element method. The algorithms are implemented in the form of computational software for assessing the reliability of structures under random loading conditions.

To implement this method, an open CAE was chosen — a system with the ability to program its own modules — the NX Open system.

The developed software is displayed on the NX panel in the form of a special icon tray Reliability.

The developed software is intended for analysis of the strength of reliability of CEA structures with random loading. The software does not have domestic or foreign alternatives. The main advantages are universality (the ability to perform calculations for a wide range of designs, taking into account the statistical nature of the initial data), the reliability of the estimated estimates, confirmed by the use of modern numerical methods: the finite element method and the statistical modelling method.
Estimation of the accuracy of numerical analysis for the deformed state of power structures of technical objects
Authors: Рогалев А.Н. , Доронин С.В. , Москвичев В.В.
Published: October 2021

Под силовыми конструкциями понимают технические устройства, составленные из различных частей, воспринимающие комплекс эксплуатационных нагрузок в штатных и аварийных режимах нагружения. При решении прикладных задач исследования напряженно-деформированных состояний силовых конструкций важна оценка степени близости к точному приближенного решения, полученного на вполне определенной сетке конечных элементов с конечной величиной шага сетки. С учетом влияния ошибок округления сходимость метода конечных элементов контролировать сложно: при большом числе конечных элементов решение может расходиться из-за накапливающихся ошибок округления, даже если условия сходимости выполняются. Описанное в статье применение методов обратного анализа ошибок позволяет достаточно точно контролировать точность численных оценок деформированного состояния силовых конструкций, что подтверждают расчеты, выполненные для практических задач.

The solution of applied problems of technogenic safety, survivability, risk and protection is performed for structures which are close to limiting states. These states are characterized by decreasing safety factors down to one. In this case a mistaken estimation for safety factor may cause the situation when the calculated safety factor will be greater than one but the real safety factor will be less than one. Safety factors estimation is performed on the basis of calculation for stress-strain state characteristics.

Thus, the issues of accuracy and reliability of determining stresses and deformations are an integral part of the problem of man-made safety. In the numerical analysis of the stress-strain state, the stiffness matrix of the design model is formed, the dimension of which reaches up to tens of millions. A large number of computations for tasks of this dimension is presumably leading to significant rounding errors. Ensuring the grid convergence of results by decreasing the grid spacing is inconsistent with the growth of computational errors due to rounding. For finite element analysis of power structures of technical objects, methods of a posteriori reverse error analysis are proposed that control the effect of rounding errors on the result when solving a solving system of linear algebraic equations. The coefficient matrix of this system is the stiffness matrix of the finite element model. The basic idea is to obtain and solve a system of equations with a known exact solution. Comparison of the results of exact and numerical solutions allows us to estimate the magnitude of the error.

The aim of the presented work is the development of an information computational
system for processing radar images with the ability to visualize, configure and run
algorithms for the main stages of processing interferometric data by the Persistent
Scatterer method integrated with the MPP system (massive parallel processing) for
high-performance monitoring of the Earth surface displacement of aerospace survey
sites.
As a result of the analysis of the different approaches used in the processing of radar
data and the review of distributed computing technologies, a distributed information
system based on the architecture of massively parallel execution of the Apache Hadoop
ecosystem processes the streaming post-processing of radar images and the construction
of a displacement map was proposed and implemented. A software implementation
is presented in the form of a web portal based on ReactJS components, including
automated downloading and updating of the Sentinel-1A radar image database using
RESTful API technology.
The innovation of suggested solution consists of the model of the interaction between
developed processing modules based on the isolated execution context with HDFS data
storage during the preparing procedure and the complete cycle for the processing of the
Earth surface displacement.
An integrated approach to the developing scalable front-end and back-end software
complex components with the use of ReactJS, Redux and Apache Spark framework was
used for the first time. Supporting of WPS specification makes it possible using almost
any GIS, which works with this standard.
The evaluation of a scientific and technological level of research shows high performance
of the developed system while maintaining the results quality. In particular,
the adapted and integrated ESA SNAP Toolbox returned identical arrays of processed
interferometric data in the per-pixel comparison but the speed of the procedure is
several times faster.
Tables of geometric, high-speed and energy characteristics for the bottom parts of a tornado
Authors: Крутова Ирина Юрьевна
Published: October 2021

В настоящей работе при заданном в таблице Фудзиты значении ширины полосы разрушений для всех торнадо установлены два внешних радиуса притока воздуха в придонную часть торнадо: in1  и rin2. Первый из этих радиусов in1  такой, что кинетическая энергия вращательного движения построенного потока составляет половину всей его кинетической энергии. При втором радиусе rin2 кинетическая энергия всего потока становится равной кинетической энергии самого слабого торнадо, при котором имеют место разрушения. Знание значений этих радиусов позволит более надежно прогнозировать возникновение торнадо.

The natural phenomenon of a tornado, known for its destructive power, is an object of study of many scientists. The available part of the data of field observations of this natural phenomenon is systematized and collected in the so-called Fujita scale. In particular, it indicates the width of the fracture band for tornadoes of different intensity, and only the values of the maximum wind speed are given from the gas dynamic parameters. Bautin S.P. proposed and justified the scheme of occurrence and functioning of natural ascending swirling flows of the tornado and tropical cyclones. Based on both this scheme and the data of the Fujita scale, the external radii of air inflow in the near-bottom parts of tornadoes of various intensities are established and the gas dynamic parameters of these flows are calculated. It turned out that in the case of the lowest intensity from the Fujita scale, the kinetic energy of the rotational motion of the air is half of the entire kinetic energy of the flow in the bottom part. As tornado intensity increases, the kinetic energy of rotational motion becomes the more prominent part of the total kinetic energy of the flow. In this paper, given the Fujita value of the width of the destruction zone for all tornadoes along with the two external radii of air inflow into the bottom part of the tornado are established as rin1  and rin2. The first of these radii, namely rin1 , denotes the radius at which the kinetic energy of the rotational motion of the constructed stream is half of all the kinetic energy of this stream. The second one denoted as rin2, is the radius at which the kinetic energy of the entire stream becomes equal to the kinetic energy of the weakest destructive tornado. Knowing the values of these radii allows reliable predicting the origin of the tornado.

Описаны специализированные методы, разработанные авторами для решения задач обработки случайных точечных изображений, в основе которых лежат построение программных систем для проведения трудоемких аналитических выкладок и использование различных расширений классических чисел Каталана. Приведены примеры эффективного применения предложенных методов для расчета точных аналитических формул, описывающих вероятность безошибочного считывания случайных дискретных полей и цифровых изображений, проводимого сканирующей апертурой с ограниченным числом пороговых уровней.

During the digital registration and subsequent processing of fast dynamic processes which have different physical nature, determination for the unknown coordinates of the point-pulse sources becomes one of the most time-consuming and algorithmically complex problems. It happens since it is necessary to satisfy the requirements for accuracy and reliability of registration in such tasks. Finding the exact analytical relationships connecting reliability of the registration with the characteristics of the physical process and the output parameters of the processing system is a problematic and very difficult task in most practically important cases, for example in the case of power of random radiation source and the size of the analyzed field. This paper proposes the methods developed by the authors for calculating the exact analytical formulas and relationships that describe the probability of error-free readout of a random point-pulse field when registration procedure is performed by a scanning aperture with a limited number of threshold levels. The specialized methods, based on the construction of software systems for laborious analytical calculations and the use of various extensions of the classical Catalan numbers are offered. In particular, procedures have been built for multidimensional integration over convex polyhedral areas with freely movable boundaries in n-dimensional space. Two probabilistic problems are also formulated, leading to an extension of the classical Catalan numbers, which turned out to be more convenient to formulate and solve in a symbolic-linguistic form.

The dependence for the Hamiltonian matrix elements of the Schrodinger torsion equation on the calculation errors of the Mathieu basis set is considered. The Mathieu functions are represented with continued fractions in this study. The analysis of the Mathieu function approximation algorithm using Fourier series expansion is carried out when the coefficients of the Fourier series are represented by convergent continued fractions. It is shown that the major contribution to the errors at the Fourier coefficient calculation is made by the error accumulating in the corresponding elements of the continued fraction. Recurrence relations for the absolute and relative errors of the kept elements of the continued fraction and the Fourier expansion coefficients are obtained. It is shown and illustrated by a numerical example that the absolute and relative errors of the Fourier expansion coefficients in the proposed algorithm are negligible. It is noted that the maximum relative errors of continued fraction are in the highest elements of the kept part.

The results of our work are used to estimate the calculation error in the integrals containing Mathieu functions. These integrals constitute the Hamiltonian matrix elements of the Schr¨odinger torsion equation. We developed an algorithm to estimate of the calculation accuracy of the Hamiltonian matrix elements of the Schr¨odinger torsion equation in the basis set of Mathieu functions. We provide the example of this algorithm. The results of the work indicate the adequacy and effectiveness at the application of the Mathieu function basis set to the solution of the Schrdinger torsion equation.¨

Extramedullary disease in acute myeloid leukemia is a known phenomenon with reported incidence of 2.5-9.1 %. However, acute kidney injury due to direct infiltration of malignant cells is reported in only 1% cases of acute leukemia. We report a case of acute myeloid leukemia who developed acute kidney failure at presentation, was diagnosed with renal and pancreatic infiltration by FDG-PET scan and was treated successfully with hypomethylating agent and venetoclax. PET-CT scan can be a non-invasive modality for diagnosing extramedullary disease in acute myeloid leukemia and monitoring of response to therapy in these cases. Early initiation of anti-leukemia therapy in our case lead to complete metabolic response with normalization of the renal functions.

This is the case of a 64-year-old man, on renal replacement therapy since 2008, due to autosomal dominant polycystic kidney disease. The patient was on peritoneal dialysis from 2008 to 2016, when he underwent renal transplantation. Transplant duration was less than a month due to acute vascular rejection. Since then, he is on hemodialysis. A few months after transplantation, it was incidentally identified confluent bilateral opacities, more prominent on the left lung in a routine X-ray (Figure 1). The patient had made a chest radiography in 2015 without any changes at that time. The CT scan showed parenchymatous densification areas, partially calcified, in both lungs (Figure 2). The patient also developed secondary hyperparathyroidism refractory to medical therapy but refused surgery. Nevertheless, the lesions had a slow progression until the present time.

Objective: The impact of Nonsteroidal Anti-Inflammatory Drugs (NSAID) and iodine-based contrast exposures on developing Chronic Kidney Disease (CKD) is controversial. We examined the association of these exposures with the development of CKD in a Veteran population. Methods: A retrospective case-control study of 154,448 veterans from the Veterans Affairs (VA) Corporate Data Warehouse (CDW) database between 2005 and 2014 was conducted to assess the association between incident stage 3 CKD with Acute Kidney Injury (AKI), NSAID use, iodine-based contrast exposures, and comorbid conditions. Stepwise logistic regression was used to determine multivariable adjusted Odds Ratios (OR). Results: The mean age was 59 (SD±13), and the median eGFR was 84 (IQR: 73, 96). AKI was associated with increased odds of CKD (inpatient: OR=3.76, 95% CI: 3.44, 4.11; outpatient: OR=4.73, 95% CI: 4.09, 5.46) and demonstrated escalated odds with >1 episode (inpatient: OR=5.72, 95% CI: 4.71, 6.95; outpatient: OR=8.36, 95% CI: 6.32, 11.06). Months of NSAID prescriptions was associated with CKD, with ORs at >0-6 months, >6-12 months, and >12 months of 1.27 (95% CI: 1.23, 1.32), 1.54 (95% CI: 1.46, 1.63), and 1.69 (95% CI: 1.62, 1.77) respectively. Iodine-based contrast exposure was associated with increased odds of CKD, with ORs for 1-2 Computed Tomography (CT) scans, ≥3CT scans, and left heart catheterization of 1.29 (95% CI: 1.24, 1.35), 1.29 (95% CI: 1.20, 1.28), and 1.38 (95% CI: 1.17, 1.63) respectively. Conclusion: AKI events, NSAID use, and iodine-based contrast exposures are associated with increased odds for developing stage 3 CKD in veterans.

Despite the global achievements to control HIV epidemic and end AIDS by 2030, there is still a discrepancy in accessing HIV services. Men are among the population that are lagging behind when it comes to consuming available services to mitigate the impact of HIV/AIDS. We conducted this study to determine the level of Rwandan men engagement in HIV services delivery. We used cross- sectional design to analyze data from a Population- based HIV impact assessment, a household-based survey conducted in Rwanda from October 2018 to March 2019. Cascade from awareness of the HIV status, linkage to ART and Viral load suppression were analyzed. Logistic regression analysis was conducted to establish relationship between independent variables and outcomes. Data cleaning and analysis was conducted using SAS 9.4. 13. A total of 821 males aged 15 to 64 years participated in the survey, 302 (2.1%) of them tested positive, 92.2% (95% CI: 89.2-95.2) reported tested once for HIV. Overall, 78.2% (95% CI: 72.4-84) reported to be aware of their status and on ART. 70.5% (95% CI: 63.8-77.2) reported to have suppressed viral load. Married or living together with a partner showed to be 7 times more likely to be on ART vs single or never married (OR: 7.42, 95% CI: (1.75;31.38), P <0.01). Odds of viral load suppression increases with age, and those aged above 55 years showed to be more suppressing their virus (OR: 3.94, (95% CI: 0.92-16.9), P=0.07). Findings from this study revealed the gaps to be closed to include all population in maximizing HIV service delivery.
