String Stable Heterogeneous Aircraft in a Windy Environment
Authors: Stephens Shawn S. , Casbeer David W. , Tran Dzung , Kunz Donald L.
Published: February 2023

This research develops and analyzes an approach to solve the continuous monitoring problem. The analysis focuses on the string stability of a system of airspeed heterogeneous nonlinear aircraft that are controlled to overfly an endpoint at specified time intervals. The system is modeled as a cascaded set of subsystems where the position of each subsystem, an individual aircraft, is based off the estimated overfly time of the preceding vehicle. The model also includes the effects of steady-state wind and turbulence. The system is made to be string stable by nondimensionalizing a portion of the dynamics, selecting variable command limits, and solving for exponentially stable controller gains. The simulation results confirm the stability guarantees of the theoretical analysis and show that a randomized group of 20 airspeed heterogeneous aircraft experiencing realistic wind and turbulence results in an estimated arrival time error that converges toward a relatively small steady-state range.
Physical development of preterm monochorionic diamniotic twins at birth: retrospective cohort study
Authors: Pavlichenko M. V. , Kosovtsova N. V. , Pospelova Ya. Yu. , Markova T. V.
Published: February 2023

Background. Much controversy surrounds the estimation of anthropometric parameters in multiple newborns. In newborn monochorionic diamniotic twins, these parameters can be affected by specific antenatal complications.

Objectives. To estimate the physical development parameters of preterm monochorionic diamniotic twins according to standards proposed within the INTERGROWTH-21st project, taking specific intrauterine complications into account.

Methods. The anthropometric data were analyzed in 148 pairs of newborn monochorionic diamniotic twins, who were divided into three groups according to the presence of specific intrauterine complications: Group I (n = 56 pairs) — twin-to-twin transfusion syndrome (TTTS); Group II (n = 38 pairs) — selective intrauterine growth restriction (sIUGR); Group III (n = 58 pairs) — absence of the above-mentioned specific complications. The obtained data were statistically processed on a personal computer via variation statistics methods using Microsoft Excel spreadsheets (Microsoft, USA) and an online service available at https://medstatistic.ru.

Results. Newborns with sIUGR (37–100.0%) and 26 (49.1%) donors fell into the category of newborns light for gestational age. Disharmonious (3–10th percentile) and markedly disharmonious (below the 3rd percentile) physical development at birth was most commonly observed in newborns with sIUGR and, to a lesser extent, in donors (OR — 9.2; 95% CI — 3.2–24.3; p < 0.05), which was noted only occasionally in monochorionic twins from other groups. A combined decrease in the values of birth centiles for head circumference, body weight, and body length was found in 13 (35.1%) newborns with sIUGR and in 12 (22.6%) donors, which may mark the severity of antenatal complications and the development of neurological deficit.

Conclusion. Monochorionic diamniotic twins include newborns having greater and lower body weights. In the newborn having a lower birth weight, specific complications associated with monochorionic multiple pregnancy result in body weight and length deficit, disharmonious development due to the lack of nourishment (22.6% in the TTTS group and 73.0% in the sIUGR group), as well as delayed head circumference growth in 56.8% of newborns with sIUGR.

Authors: Lyasnikova M. B. , Belyakova N. A. , Tsvetkova I. G. , Rodionov A. A. , Lareva A. V.
Published: February 2023

Background. The relevance of alimentary-constitutional obesity, especially its severe forms, is associated with a number of metabolic disorders, subsequently leading to serious chronic noncommunicable diseases.

Objective. To identify factors that increase the risk of severe alimentary-constitutional obesity and metabolic disorders.

Methods. A follow-up group of 426 patients aged 18 to 65 years was formed among those seeking help from an endocrinologist for overweight or obesity. The diagnosis of alimentary-constitutional obesity was confirmed at the initial examination in the outpatient clinic setting. Depending on the severity of obesity and the type of fat deposition according to anthropometric data (body mass index, waist circumference), the study participants were ratified into two study groups. The research was conducted between 2010 and 2017 in outpatient settings and was based on a cross-sectional comparative study. In order to assess the risk of severe obesity and factors associated with it, the authors studied medical history data, results of physical examination, including blood pressure level, laboratory examination with analysis of carbohydrate, fat metabolism and liver function, assessed eating behaviour, and performed diagnosis of anxiety-depressive disorder. Statistical analysis of the results was carried out using Statistica 10 (StatSoft, USA).

Results. Women are more likely to see an endocrinologist with less severe obesity than men. Severe obesity risk is higher in middle-aged and elderly people, as well as in hereditary tainted patients and those having a history of obesity for more than 10 years. Severe obesity itself is a significant risk for metabolic events, with a 4-fold higher risk of hyperglycaemia and hypercholesterolaemia (due to very low density lipoproteins) and a 5-fold higher risk of hyperinsulinaemia and insulin resistance.

Conclusion. Analysis of severe obesity risks has shown that earlier personal commitment to a healthy lifestyle is essential for weight loss and subsequent improvement of metabolic parameters, particularly in men and those aged 45 years or older.
Clinical and Morphological Analysis of Efficacy of Intraperitoneal Ozone Application in Experimental Colitis: Preclinical Randomized Experimental Study
Authors: Osikov M. V. , Kaygorodtceva N. V. , Boyko M. S. , Astachova L. V.
Published: February 2023

Background. Inflammatory bowel diseases — Crohn’s disease and ulcerative colitis — are chronic gastrointestinal diseases affecting young people of working age. An alternative to basic therapy (5-aminosalicylic acid) for inflammatory bowel disease is the use of ozone, which has anti-inflammatory, immunomodulatory, antibacterial properties and no side effects in therapeutic concentrations. Objective. To perform clinical and morphological analysis of efficacy of intraperitoneal ozone application in experimental colitis.

Methods. The study was conducted on 73 male Wistar rats weighing 200-250 g. The animals were divided into four groups by simple randomization. Check studies were performed on the second, fourth and sixth days. Oxazolone-induced colitis was simulated in two stages using a 3%-alcohol oxazolone solution. Ozone-acid mixture was obtained on “UOTA-60-01” unit (“Medozone”, Russia). Rectal suppositories with 5-aminosalicylic acid were prepared on the basis of rectal suppositories “Salofalk”. Clinical status was assessed daily according to the disease activity index (DAI) scale. Morphological evaluation of colon lesion tissue fragments was carried out using a PrimoStar microscope (CarlZeiss, Germany). Colon tissue damage was assessed using tissue damage index (TDI). Statistical analysis was conducted with SPSS Statistics 19 (IBM, USA).

Results. Clinical and morphological picture of the large intestine lesion in oxazolone-induced colitis on days 2, 4 and 6 is consistent with the changes typical of inflammatory bowel disease in humans. Daily intraperitoneal insufflation of ozone at a dose of 0.05 mg/kg in oxazolone-induced colitis leads to partial restoration of DAI, reduction in neutrophils, eosinophils, histiocytes, and fibroblasts in the lesion, as well as to a decrease in ulcerous defect diameter and TDI. The effects of intraperitoneal insufflations of ozone in oxazolone-induced colitis as compared to rectal suppositories with 50 mg of 5-aminosalicylic acid every 12 hours were less marked for the DAI index on day 4; for the number of eosinophils, plasma cells, histiocytes — on day 2, 4 and 6; for lymphocytes — on day 6.

Conclusion. Clinical and morphological picture of the large intestine lesion in ozone-induced colitis correlates with the changes typical of inflammatory bowel disease in humans. The positive effect of ozone in ozone-induced colitis was driven by its anti-inflammatory properties through the activation of Nrf2 and by its antioxidant properties through the inhibition of Keap1.

Published: February 2023

Objetivo: Analisar as características do Implante Coclear (IC), seu funcionamento, suas indicações e complicações. Revisão bibliográfica: Mais de 500 milhões de pessoas em todo o mundo sofrem de perda auditiva, a qual pode comprometer a comunicação por ocasionar danos no desenvolvimento de habilidades cognitivas, emocionais, educacionais, socioeconômicas, além de influenciar de forma negativa a dinâmica familiar do indivíduo. Nesse sentido, o IC tem sido a tecnologia que gera expectativas e traz benefícios para indivíduos com DA neurossensorial severa e/ou profunda que não se beneficiam de outros aparelhos auditivos. Os ICs contornam o mecano transdutor natural do ouvido interno e fornecem estimulação elétrica diretamente aos neurônios auditivos. Para os indivíduos com perda auditiva severa a profunda, especialmente bilateral, a melhor terapêutica é o implante  coclear. Considerações finais: O diagnóstico precoce e preciso é crucial para o sucesso da reabilitação auditiva da deficiência auditiva de alto grau. A reabilitação auditiva com o implante coclear está associada à melhora significativa, não apenas da audição e da compreensão da linguagem falada, mas também da qualidade de vida em qualquer faixa etária.

Salmon evolve quickly as a response to intense harvesting of their prey
Authors: Czorlich Yann
Published: February 2023

To persist in the face of climate change and human activities, organisms may need to adapt. We showed that Atlantic salmon from River Teno (between Finland & Norway) evolved over the last 40 years to mature earlier. Our data suggest it was due to indirect and direct effects of fishing: harvesting of capelin to feed farmed animals, and size selective net fishing in the river.
Electrochemical Hydrogen Isotope Exchange of Amines Controlled by Alternating Current Frequency
Authors: Behera Nibedita , Gunasekera Disni , Mahajan Jyoti , Frimpong Joseph , Liu Zhenfei , Luo Long
Published: February 2023

Here, we report an electrochemical protocol for hydrogen isotope exchange (HIE) at -C(sp3)-H amine sites. Tetrahydroisoquinoline and pyrrolidine are selected as two model substrates because of their different proton transfer (PT) and hydrogen atom transfer (HAT) kinetics at the -C(sp3)-H amine sites, which are utilized to control the HIE reaction outcome at different applied alternating current (AC) frequencies. We found the highest deuterium incorporation for tetrahydroisoquinolines at 0 Hz (i.e., direct current (DC) electrolysis condition) and pyrrolidines at 0.5 Hz. Analysis of the product distribution and D incorporation at different frequencies reveals that HIE of tetrahydroisoquinolines is limited by its slow HAT, whereas HIE of pyrrolidines is limited by the overoxidation of its -amino radical intermediates. The AC-frequency-dependent HIE of amines can be potentially used to achieve elective labeling of -amine sites in one drug molecule, which will significantly impact the pharmaceutical industry.
Comparing Ab Initio Molecular Dynamics and a Semiclassical Grand Canonical Scheme for the Electric Double Layer of the Pt(111)/Water Interface
Authors: Huang Jun , Zhang Yufan , Li Mengru , Groß Axel , Sakong Sung
Published: February 2023

The theoretical modeling of metal/water interfaces centers on an appropriate configuration of the electric double layer (EDL) under grand canonical conditions. In principle, ab initio molecular dynamics (AIMD) simulations would be the appropriate choice for treating the competing water-water and water-metal interactions and explicitly considering the atomic and electronic degrees of freedom. However, this approach only allows simulations of relatively small canonical ensembles over a limited period (shorter than 100 ps). On the other hand, computationally efficient semiclassical approaches can treat the EDL model based on a grand canonical scheme by averaging the microscopic details. Thus, an improved description of the EDL can be obtained by combining AIMD simulations and semiclassical methods based on a grand canonical scheme. By taking the Pt(111)/water interface as an example, we compare these approaches in terms of the electric field, water configuration, and double-layer capacitance. Furthermore, we discuss how the combined merits of the approaches can contribute to advances in EDL theory.

Authors: Frawley Andrew , Leslie Kathryn , Wycisk Virginia , Galiani Silvia , Shrestha Dilip , Eggeling Christian , Anderson Harry
Published: February 2023

A switchable solvatochromic fluorescent dyad can be used to map ordering of lipids in vesicle membranes at a resolution better than the diffraction limit. Combining a Nile Red fluorophore with a photochromic spironaphthoxazine quencher allows the fluorescence to be controlled using visible light, via photoswitching and FRET quenching. Synthetic lipid vesicles of varying composition were imaged with an average 2.5-fold resolution enhancement, compared to the confocal images. Ratiometric detection was used to probe the membrane polarity, and domains of different lipid ordering were distinguished within the same membrane.
Understanding the Impact of E-Wom on Purchase behavior Using Information Acceptance Model
Authors: Yahya Reham , Ellahi Jonathan Fazal , Davi Rafia Noor , Reza Sajjida
Published: February 2023

Purpose: This study determines the influence of information gained from electronic word of mouth (e-WOM) on the purchase behavior of customers.

Design/Methodology/Approach: The conceptual model developed has been derived from the Information Acceptance Model (IAM) and the work of other researchers. The pre-existing model has been modified by increasing the factors which augment the information usefulness of e-WOM. The factor of trust inclination towards information received through online forums has also been incorporated in the model to further develop an understanding regarding the variables in the purchase decision process. This study also highlights some aspects of theory of reasoned action and theory of planned behavior as a base for this work. Structural Equation Modelling (SEM) has been used to analyze the relationship between all existing variables in the linear model.

Findings: The results show how usefulness of information obtained through social networking sites and other online media influence the adoption of this information, eventually leading to developing intention and terminal purchase behavior. However, the relationship of credibility of information, perceived risk and argument quality with information usefulness, as its antecedents, has been found insignificant, one of the primary reason for which is the unawareness of e-WOM among the general public.

Implications/Originality/Value: The practical implications of this paper include guidance to manufacturers and service providers to understand the factors involved in influencing consumer purchase behavior when subjected to e-WOM.
A Study of Morbidity and Mortality from COVID-19 in India
Authors: Eissa Dalia Essam , Rashed Engy Refaat , Eissa Mostafa Essam
Published: February 2023

The recent Human Coronavirus 2019 (hCoV-19) pandemic has devastated the whole world and impacted all aspects of human life. One of the most comprehensively recorded data for this outbreak is the daily morbidities and mortalities record. The analysis of this dataset would provide insight into the pattern and progression of this disease. The present study focused on the quantitative investigation and descriptive statistical examination of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as part of a series of evaluations for this epidemic in the primarily affected geopolitical regions. The year 2021 is worse than 2020 in terms of the recorded daily newly emerging cases and deaths, and there are no signs that there would be an improvement in 2022, as could be estimated from early warning signs, even if there could be an apparent decline in the outbreak waves. India is one of the major countries that have been adversely affected by this global pandemic. The present study addressed this nation as a detailed record of COVID-19 cases and deaths extracted from a chronologically arranged dataset for the newly emerged cases and deaths on a daily basis. Cumulative counts were calculated and logarithmically transformed. Two significant peaks - embracing multiple waves - were observed with tailing for morbidity and mortality, which were highly correlated. There were no signs of a recession in the outbreak census. However, relative calm periods between waves might be detected. There were rising trends in morbidities and mortalities with a clustering tendency upon examination of the run charts. The Morgan-Morgan-Finney (MMF) model was found to demonstrate the best-fitting non-linear curve for the transformed cumulative database. Derivatization of the model equation demonstrated a factor that could be used in the assessment of the outbreak effect numerically to show influence on the impacted population. Doi: 10.28991/SciMedJ-2022-0401-03 Full Text: PDF

The article is devoted to the study of the constitutional right to housing and the analysis of the specific content of this subjective right.

Social rights and freedoms are one of the foundations of a democratic, legal and, especially, social state (Articles 1, 7 of the Constitution of the Russian Federation). One of the most important social rights is the right to housing. The need for housing is one of the primary human needs. Today, housing performs the functions of a place of rest, home life, study, work, communication, consumption of material and spiritual benefits, providing comfortable conditions for a healthy existence and protection from cold, heat, other conditions, and the like.

It is not surprising that the right to housing is considered by the international community as one of the elements of the right to a decent standard of living (Article 25 of the Universal Declaration of Human Rights, Article 11 of the International Covenant on Economic, Social and Cultural Rights). At the same time, in the Russian constitutional law, the right to housing is positioned as an independent constitutional right.

After analyzing the normative prescriptions of the Constitution of the Russian Federation, it becomes clear that the right of citizens to housing should be attributed to socio-economic rights and freedoms. The right of citizens to housing corresponds with such constitutional rights and freedoms as: the right to inviolability of the home, the right to private property, the right to free choice of place of stay and residence, and the right to personal dignity. In modern scientific doctrine, the right to housing is a constitutionally guaranteed opportunity for a citizen to satisfy the need for housing in one of the ways determined by law.
