Authors: Громов Юрий Юрьевич , Трубиенко Олег Владимирович , Карасев Павел Игоревич , Желобенко Кирилл Александрович 
Published: August 2021

Индустрия браузеров существует в основном за счет косвенных источников финансирования, поэтому создатели браузеров должны заботиться о привлекательности предлагаемого продукта. При выборе браузера пользователь руководствуется соображениями красоты, удобства и скорости работы. Большинство пользователей в современном мире не являются технически подготовленными, это обычные люди, которые подбирают товары в магазинах или общаются в соцсетях и т. п. Они имеют смутные представления об информационной безопасности и часто пренебрегают ею либо, наоборот, начинают бояться вмешательства в частную жизнь и не знают, как себя обезопасить или как проверить ее обеспечение. Поэтому основная ответственность обеспечения информационной безопасности лежит на создателях браузера и зависит от их добросовестности и компетенции. Одна из задач специалистов по информационной безопасности - помогать улучшать сервисы с точки зрения их безопасности. С этой целью в работе проведен анализ безопасности четырех браузеров, которые были изначально представлены как браузеры для безопасного и анонимного пользования. Задача обзора и анализа заключается в определении наиболее безопасного и конфиденциального инструмента для веб-серфинга, а также выявления содержания в этих браузерах вредоносных кодов.
The browser industry is largely driven by indirect funding, so browser makers should be concerned about the attractiveness of the product they offer. When choosing a browser, the user is guided by considerations of beauty, convenience and speed of work. Most users in the modern world are not technically trained, they are ordinary people who pick up products in stores or communicate on social networks, etc. They have a vague idea of information security, and often neglect it, or, on the contrary, begin to fear interference with their privacy and do not know how to protect themselves or how to check its provision. Therefore, the main responsibility for ensuring information security lies with the creators of the browser and depends on their integrity and competence. One of the tasks of information security professionals is to help improve services in terms of their security. To this end, the work carried out a security analysis of four browsers that were originally presented as browsers for safe and anonymous use. The task of the survey and analysis is to determine the most secure and confidential tool for web surfing, as well as to identify the content of malicious codes in these browsers.
Imaging Sources in the Third Realization of the International Celestial Reference Frame

Published: August 2021

Abstract
The third iteration of the International Celestial Reference Frame (ICRF3) is made up of 4536 quasars observed at S/X bands using very-long-baseline interferometry. These sources are high-redshift quasars, typically between 1 < z < 2, that are believed to host active galactic nuclei at their centers. The position of compact radio sources can be determined better than sources with large amounts of extended radio structure. Here we report information on a series of 20 observations from 2017 January through December 2017 that were designed for precise astrometry and to monitor the structure of sources included in the ICRF3. We targeted 3627 sources over the one year campaign and found the median flux density of 2697 detected sources at S band is 0.13 Jy, and the median flux density of 3209 sources detected at X band is 0.09 Jy. We find that 70% of detected sources in our campaign are considered compact at X band and ideal for use in the ICRF and 89% of the 2615 sources detected at both frequencies have a flat spectral index, α > 0.5
Constraining Spatial Densities of Early Ice Formation in Small Dense Molecular Cores from Extinction Maps
Authors: Chu Laurie E. U. , Hodapp Klaus W. 
Published: August 2021

Abstract
Tracing dust in small dense molecular cores is a powerful tool to study the conditions required for ices to form during the prestellar phase. To study these environments, five molecular cores were observed: three with ongoing low-mass star formation (B59, B335, and L483), and two starless collapsing cores (L63 and L694-2). Deep images were taken in the infrared JHK bands with the United Kingdom Infrared Telescope WFCAM (Wide Field Camera) instrument and IRAC channels 1 and 2 on the Spitzer Space Telescope. These five photometric bands were used to calculate extinction along the line of sight toward background stars. After smoothing the data, we produced high spatial resolution extinction maps (∼13″–29″). The maps were then projected into the third dimension using the AVIATOR algorithm implementing the inverse Abel transform. The volume densities of the total hydrogen were measured along lines of sight where ices (H2O, CO, and CH3OH) have previously been detected. We find that lines of sight with pure CH3OH or a mixture of CH3OH with CO have maximum volume densities above 1.0 × 105 cm−3. These densities are only reached within a small fraction of each of the cores (∼0.3%–2.1%). CH3OH presence may indicate the onset of complex organic molecule formation within dense cores, and thus we can constrain the region where this onset can begin. The maximum volume densities toward star-forming cores in our sample (∼(1.2–1.7) × 106 cm−3) are higher than those toward starless cores (∼(3.5–9.5) × 105 cm−3).

Abstract
Hydrogen emissions of RR Lyrae variables are the imprints of shock waves traveling through their atmospheres. We develop a pattern recognition algorithm, which is then applied to single-epoch spectra of the Sloan Digital Sky Survey and the Large Sky Area Multi-Object Fiber Spectroscopic Telescope survey. These two spectroscopic surveys covered ∼10,000 photometrically confirmed RR Lyrae stars. We discovered in total 127 RR Lyrae stars with blueshifted Balmer emission features, including 103 fundamental mode (RRab), 20 first-overtone (RRc), 3 double-mode (RRd), and 1 Blazhko-type (temporary classification for RR Lyrae stars with strong Blazhko modulation in the Catalina sky survey that cannot be characterized) RR Lyrae variable. This forms the largest database to date of the properties of hydrogen emission in RR Lyrae variables. Based on Zwicky Transient Facility DR5, we carried out a detailed light-curve analysis for the Blazhko-type RR Lyrae star with hydrogen emission of long-term modulations. We characterize the Blazhko-type RR Lyrae star as an RRab and point out a possible Blazhko period. Finally, we set up simulations on mock spectra to test the performance of our algorithm and on the real observational strategy to investigate the occurrence of the “first apparition.”
No Large Dependence of Planet Frequency on Galactocentric Distance

Published: August 2021

Abstract
Gravitational microlensing is currently the only technique that helps study the Galactic distribution of planets as a function of distance from the Galactic center. The Galactic location of a lens system can be uniquely determined only when at least two of the three quantities that determine the mass–distance relations are measured. However, even if only one mass–distance relation can be obtained, a large sample of microlensing events can be used to statistically discuss the Galactic distribution of the lenses. In this study, we extract the Galactic distribution of planetary systems from the distribution of the lens-source proper motion, μ
rel, for a given Einstein radius crossing time, t
E, measured for the 28 planetary events in the statistical sample by Suzuki et al. Because microlensing is randomly caused by stars in our Galaxy, the observational distribution can be predicted using a Galactic model. We incorporate the planet-hosting probability,

P

, into a Galactic model for random-selected stars, where M
L is the lens mass (∼host mass), and R
L is the Galactocentric distance. By comparing the observed distribution with the model-predicted μ
rel distribution for a given t
E at various combinations of (m, r), we obtain an estimate r = 0.2 ± 0.4 under a plausible uniform prior for m of 0 < m < 2. This indicates that the dependence of the planet frequency on the Galactocentric distance is not large, and suggests that the Galactic bulge does have planets.
L’orphisme romanesque à la lumière d’Arthur Machen
Authors: Kunkel Samuel 
Published: August 2021

Souvent associé au genre poétique, à la fin du xix e siècle, on peut observer une application de la philosophie artistique de l’orphisme au genre romanesque. Si la finalité du poète orphique de l’époque 1900 était de créer une œuvre dans laquelle les paroles incarnent une facette du divin, tel n’est pas le souhait du romancier orphique, qui cherche plutôt à avertir un lecteur béotien de la réalité et la possibilité d’une expérience mystique — et ce afin de fournir un contrepoint spirituel au climat de pessimisme engendré par la laïcisation et la décadence de la société d’alors. Dans un tel contexte, les romans de l’écrivain gallois Arthur Machen paraissent particulièrement intéressants. Reconnaissant toute forme d’expression humaine comme insuffisante pour brosser la complexité intégrale de Dieu, ainsi que toute expérience mystique, Machen n’ambitionne pas de décrire le divin, mais plutôt ses effets sur l’esprit de l’individu. Ceci se fait par une modification de la syntaxe narrative qui cherche désormais à reproduire les modulations internes que subit la pensée humaine lorsque le sujet passe entre dans un état d’extase en présence du divin. Ainsi, les romans mystiques de Machen ont pour finalité d’agir comme un catalyseur, déclenchant un éveil chez le lecteur, et le poussant à renouer avec sa propre spiritualité en-dehors du monde diégétique.
L’éthique du care en situation de pandémie : quels changements possibles ?
Authors: Dalmiya Vrinda , Rollet Brigitte 
Published: August 2021

Cet article traite des articulations spécifiques du care proposées par trois éminentes théoriciennes du concept – Eva Kittay, Joan Tronto, et Maria Puig de la Bellacasa – afin d’analyser les aspects pratiques du Covid-19 aux États-Unis et en Inde. La question centrale est de savoir si une analyse de la pandémie par le care peut amorcer des imaginations radicalement différentes du “vivre ensemble” dans un monde post-Covid. Après avoir examiné certains obstacles à l’adoption des changements profondément relationnels de la perspective du soin, j’examinerai si notre réponse aux crises contient une « auto-réflexion pragmatique » implicite des cadres néolibéraux bien enracinés et fondés sur l’individualité atomisée, la responsabilité individualisée et les valeurs du fondamentalisme de marché.

Authors: Akar Serpil , Gokyigit Birsen , Kayaarasi Ozturker Zeynep 
Published: August 2021

Purpose:
To evaluate the surgical results of full horizontal tendon rectus muscle transposition to the superior rectus muscle insertion, augmented by posterior fixation sutures, in patients with double elevator palsy.

Methods:
In this retrospective comparative study, 17 patients treated by the augmented Knapp procedure (study group) were compared with 28 patients treated by the standard Knapp procedure (control group). Pre-operative and postoperative vertical deviation in primary position, ocular motility, binocular function, and rate of reoperation were evaluated.

Results:

The mean preoperative near and distance deviations (hypotropia) decreased by 93% and 97% in the study group and 68% and 69% in the control group, respectively. The improvement in near and distance deviation was statistically more significant in the study group than the control group (
P
= .001 for each parameter). The mean preoperative elevation deficiency in abduction and adduction improved by 64% and 66% in the study group and 37% and 39% in the control group, respectively. The improvement in elevation deficiency in abduction and adduction was statistically significantly greater in the study group than the control group (
P
= .001 and .04, respectively). Reoperation was required in 15 patients (54%) in the control group and 2 (12%) in the study group during the follow-up period of 26 ± 4 months.

Conclusions:
The postoperative improvement in near and distance deviation and elevation deficiency in abduction and adduction was significantly better in the augmented Knapp procedure than the standard Knapp procedure. This procedure demonstrated a stronger effect in the treatment of double elevator palsy.

Published: August 2021

Background :
Transcatheter pulmonary valve implantation (TPVI) is a surgical alternative for correcting dysfunctional right ventricular outflow tract conduits in previously operated patients. MyVal transcatheter heart valve (THV) (Meril Life Sciences, India), a new transcatheter valve designed for aortic position has not been used for TPVI.

Methods :
Patients with stenosed dysfunctional conduits from the right ventricle to pulmonary artery (RV-PA) were prestented after initial computed tomography and balloon interrogation before the implantation of MyVal. Size of MyVal was chosen based on the final diameter of the prestent. Procedural details and post-TPVI follow-up were analyzed.

Results :
Seven patients aged 17–60 years (median 26 years) had stenosed RV-PA conduits implanted 5–17 years (median 9 years) ago for tetralogy of Fallot in three, following Ross procedure in two, repair of pulmonary stenosis, and following PA debanding in one patient each. Prestenting improved the conduit diameter from 9.3 ± 2.8 mm to 20.8 ± 1.1 mm and relieved the gradient from 87.3 ± 31.7 mmHg (50–137 mmHg) to 12.7 ± 6.4 mmHg (5–20 mmHg). A 23 mm MyVal was implanted in all the seven patients successfully; one patient needed an additional 24.5 mm MyVal valve in valve implantation for residual regurgitation. The mean fluoroscopic time and dose area product were 38.7 ± 25.3 min and 66.917 ± 39.211Gray. cm2, respectively. At a median follow-up duration of 16 months (10–22 months), all patients were asymptomatic receiving dual antiplatelet therapy with no PR and the gradient was 12.5 ± 5.8 mmHg on echocardiography. Although one patient needed an additional valve-in-valve implantation, there were no valve-related adverse events.

Conclusions :
Early experience of TPVI with MyVal THV in prestented conduits is encouraging with procedural success in all patients and acceptable mid-term outcomes.

Background: Although large families are desired in Nigeria, women tend to want fewer children than men but are often unable to limit or space childbirth due to gender dynamics within relationships. Studies have identified men as a significant barrier to the use of contraceptives by their wives. The study explored married men’s knowledge and perception on family planning (FP), involvement in FP, barriers and facilitators of male involvement (MI) in FP in Sokoto Metropolis.Methods: A qualitative study was done among married men in Sokoto Metropolis in November 2017. Four focus group discussions were conducted among thirty-two men grouped based on educational status and age. Data was transcribed verbatim and a content analysis on emerging themes was done.Results: All the participants were aware of FP and most of them said that it is beneficial to everyone in the community. Most of the participants perceived that FP is an issue for both men and women. All the participants said that men should be involved in FP. The barriers to MI in FP mentioned were lack of knowledge on FP and poverty while increasing awareness on FP, religious leaders and traditional rulers championing FP, and making FP free were the facilitators suggested.Conclusion: The participants said that FP is beneficial to everyone in the community and men should be involved in FP. Traditional and religious leaders should be made the champions of FP in their various communities to improve acceptance and utilisation.
