Published: March 2022

Введение. Существующие методы лечения гигром характеризуются как надежные и безопасные. Однако до 40% синовиальных кист рецидивируют в течение 1 года после хирургического лечения. Для комплексного лечения заболевания необходимо радикально удалить образование, устранить слабость синовиальной оболочки на данном участке и направить пролиферативную фазу репарации в сторону максимального формирования оформленной плотной соединительной ткани.Цель. Оптимизация и стандартизация метода чрескожной малоинвазивной лазерной деструкции синовиальных кист различной локализации.Материалы и методы. Исследование было разделено на три этапа. На первом этапе выполнялось математическое моделирование лазерной деструкции гигром для определения оптимальных параметров лазерного излучения и длительности экспозиции. На втором этапе выполнялось экспериментальное исследование на лабораторных животных для изучения процессов репарации тканей, подвергшихся воздействию лазерного излучения с различными параметрами. На третьем этапе выполнялось клиническое исследование для определения оптимальной методики хирургического лечения у пациентов с различной локализацией гигром. Результаты и обсуждение. Полученные данные в ходе компьютерного моделирования, экспериментального исследования подтверждают и дополняют друг друга.Выводы. Лазерная деструкция не уступает существующим методам лечения по безопасности и эффективности, а также превосходит их по комфорту для пациента.
Introduction. The existing methods of synovial cyst treatment are characterized as reliable and safe. However, up to 40% of synovial cysts recur within 1 year after surgical treatment. Thus, for the complex treatment of the disease, it is necessary to radically remove the formation, eliminate the weakness of the synovial membrane in this area, and direct the proliferative phase of repair towards the maximum formation of the formed dense connective tissue.Purpose. To optimize and standardize the method of percutaneous minimally invasive laser destruction of synovial cysts of various localization.Materials and methods. The study was divided into three phases. At the first stage, the mathematical modeling of synovial cyst laser destruction was performed to determine the optimal parameters of laser radiation and exposure duration. At the second stage, the experimental research was performed on laboratory animals to study the tissue repair processes exposed to laser radiationwith various parameters. At the third stage, the clinical study was performed to determine the optimal surgical treatment technique for patients with different localization of synovial cysts.Results and discussion. The data obtained during computer modeling, experimental and clinical researches confirm and complement each other.Conclusions. Laser destruction is not inferior to the existing treatment methods in terms of safety and effectiveness, and it also surpasses them in patient comfort.

Territorializações agroecológicas: saberes, práticas e políticas de natureza em comunidades rurais tradicionais do Paraná
Authors: Floriani Nicolas , Floriani Dimas , De Almeida Silva Adnilson , Haliski Antonio Marcio 
Published: March 2022

This text discusses some results from research on the formation of agroecological networks and subjects in traditional rural communities in the Center-South and Campos Gerais regions of Paraná state. We begin from the discussion of agroecology as a field for social production of knowledge and practices, through which cooperation strategies, disputes, and tensions between different actors at local, regional, and national scales become evident. To do so, three dimensions that mobilize resources and expand capacities for a relative socio-environmental autonomy that theoretically could be driven by agroecological projects are discussed: organizational, epistemological, and technological. A wide variety of social strategies for appropriating, producing, and legitimizing agroecological discourses and practices that reveal territorialization strategies for multiple motives (local social organizations, universities, unions and cooperatives, municipal, state, and federal government) can be seen. Notable among the competing agroecological imagery is that which resembles an ethics of peasantry and traditional knowledge, often diverging from the official scientific and institutional hegemonic beliefs in some aspects with regard to the autonomy of the three dimensions mentioned above. On these terms, we question to what extent various agroecological practices and imagery can mobilize social and ecological capital when appropriated (adapted and hybridized) by local rural communities in order to produce subjectivities and autonomies based on an ethics of peasantry.elocation-id: e2230103Received: 08.24.2021 • Accepted: 02.04.2022 • Published: 02.23.2022Original article / Blind peer review / Open access

Better together? Social distance affects joint probability discounting
Authors: Schwenke Diana , Senftleben Ulrike , Scherbaum Stefan 
Published: March 2022

AbstractDeciding together is common in our everyday life. However, the process of this joint decision-making plays out across different levels, for example language, intonation, or non-verbal behaviour. Here we focused on non-verbal interaction dynamics between two participants in probability discounting. We applied a gamified decision-making task in which participants performed a series of choices between a small but safe and a large but risky reward. In two experiments, we found that joint decision-making resulted in lower discounting and higher efficiency. In order to understand the underlying mechanisms in greater detail, we studied through which process this variation occurred and whether this process would be modulated by the social distance between both participants. Our findings suggested that socially close participants managed to reduce their discounting by interactive processes while socially distant participants were influenced by the social context itself. However, a higher level of efficiency was achieved through interactive processes for both groups. In summary, this study served as a fine-grained investigation of collaborative interaction processes and its significant impact on the outcome of choices with probabilistic consequences.

Published: March 2022

Abstract
We present results from high-resolution (R ∼ 40,000) spectroscopic observations of over 200 metal-poor stars, mostly selected from the RAVE survey, using the Southern African Large Telescope. We were able to derive stellar parameters for a total of 108 stars; an additional sample of 50 stars from this same effort was previously reported on by Rasmussen et al. Among our newly reported observations, we identify 84 very metal-poor (VMP; [Fe/H] < −2.0, 53 newly identified) stars and three extremely metal-poor (EMP; [Fe/H] < −3.0, one newly identified) stars. The elemental abundances were measured for carbon, as well as several other α-elements (Mg, Ca, Sc, and Ti), iron-peak elements (Mn, Co, Ni, and Zn), and neutron-capture elements (Sr, Ba, and Eu). Based on these measurements, the stars are classified by their carbon and neutron-capture abundances into carbon-enhanced metal-poor (CEMP; [C/Fe] > +0.70), CEMP subclasses, and by the level of their r-process abundances. A total of 17 are classified as CEMP stars. There are 11 CEMP-r stars (eight newly identified), one CEMP-s star (newly identified), two possible CEMP-i stars (one newly identified), and three CEMP-no stars (all newly identified) in this work. We found 11 stars (eight newly identified) that are strongly enhanced in r-process elements (r-II; [Eu/Fe] > +0.70), 38 stars (31 newly identified) that are moderately enhanced in r-process elements (r-I; +0.30 < [Eu/Fe] ≤ + 0.70), and one newly identified limited-r star.
A Physical Model of Delayed Rebrightenings in Shock-interacting Supernovae without Narrow-line Emission
Authors: Coughlin Eric R. , Zrake Jonathan 
Published: March 2022

Abstract
Core-collapse supernovae can display evidence of interaction with preexisting, circumstellar shells of material by rebrightening and forming spectral lines, and can even change types as hydrogen appears in previously hydrogen-poor spectra. However, a recently observed core-collapse supernova—SN 2019tsf—was found to brighten after roughly 100 days after it was first observed, suggesting that the supernova ejecta was interacting with surrounding material, but it lacked any observable emission lines and thereby challenged the standard supernova-interaction picture. We show through linear perturbation theory that delayed rebrightenings without the formation of spectral lines are generated as a consequence of the finite sound-crossing time of the postshock gas left in the wake of a supernova explosion. In particular, we demonstrate that sound waves—generated in the postshock flow as a consequence of the interaction between a shock and a density enhancement—traverse the shocked ejecta and impinge upon the shock from behind in a finite time, generating sudden changes in the shock properties in the absence of ambient density enhancements. We also show that a blast wave dominated by gas pressure and propagating in a wind-fed medium is unstable from the standpoint that small perturbations lead to the formation of reverse shocks within the postshock flow, implying that the gas within the inner regions of these blast waves should be highly turbulent.
Performance Enhancement of Tree-based Friends-of-friends Galaxy Finder for High-resolution Simulations of Galaxy Formation
Authors: Rhee Jinsu , Elahi Pascal , Yi Sukyoung K. 
Published: March 2022

Abstract
Cosmological simulations are useful tools for studying the evolution of galaxies, and it is critical to accurately identify galaxies and their halos from raw simulation data. The friends-of-friends (FoF) algorithm has been widely adopted for this purpose because of its simplicity and expandability to higher dimensions. However, it is cost-inefficient when applied to high-resolution simulations because standard FoF implementation leads to too many distance calculations in dense regions. We confirm this through our exercise of applying the six-dimensional (6D) FoF galaxy finder code, VELOCIraptor, on the NewHorizon simulation. The high particle resolution of NewHorizon (M
star ∼ 104
M
⊙) allows a large central number density (106 kpc−3) for typical galaxies, resulting in a few days to weeks of galaxy searches for just one snapshot. Even worse, we observed a significant decrease in the FoF performance in the high-dimensional 6D searches: “the curse of dimensionality” problem. To overcome these issues, we have developed several implementations that can be readily applied to any tree-based FoF code. They include limiting visits to tree nodes, reordering the list of particles for searching neighbor particles, and altering the tree structure. Compared to the run with the original code, the new run with these implementations results in the identical galaxy detection with the ideal performance,

The Importance of Horizontal Poynting Flux in the Solar Photosphere

Published: March 2022

Abstract
The electromagnetic energy flux in the lower atmosphere of the Sun is a key tool to describe the energy balance of the solar atmosphere. Current investigations on energy flux in the solar atmosphere focus primarily on the vertical electromagnetic flux through the photosphere, ignoring the Poynting flux in other directions and its possible contributions to local heating. Based on a realistic Bifrost simulation of a quiet-Sun (coronal hole) atmosphere, we find that the total electromagnetic energy flux in the photosphere occurs mainly parallel to the photosphere, concentrating in small regions along intergranular lanes. Thereby, it was possible to define a proxy for this energy flux based on only variables that can be promptly retrieved from observations, namely, horizontal velocities of the small-scale magnetic elements and their longitudinal magnetic flux. Our proxy accurately describes the actual Poynting flux distribution in the simulations, with the electromagnetic energy flux reaching 1010 erg cm−2 s−1. To validate our findings, we extended the analysis to Sunrise/IMaX data. First, we show that Bifrost realistically describes photospheric quiet-Sun regions, as the simulation presents similar distributions for line-of-sight magnetic flux and horizontal velocity field. Second, we found very similar horizontal Poynting flux proxy distributions for the simulated photosphere and observational data. Our results also indicate that the horizontal Poynting flux in the observations is considerably larger than the vertical electromagnetic flux from previous observational estimates. Therefore, our analysis confirms that the electromagnetic energy flux in the photosphere is mainly horizontal and is most intense in localized regions along intergranular lanes.
A Star-sized Impact-produced Dust Clump in the Terrestrial Zone of the HD 166191 System

Published: March 2022

Abstract
We report on five years of 3–5 μm photometry measurements obtained by warm Spitzer to track the dust debris emission in the terrestrial zone of HD 166191 in combination with simultaneous optical data. We show that the debris production in this young (∼10 Myr) system increased significantly in early 2018 and reached a record high level (almost double by mid 2019) by the end of the Spitzer mission (early 2020), suggesting intense collisional activity in its terrestrial zone likely due to either initial assembling of terrestrial planets through giant impacts or dynamical shake-up from unseen planet-mass objects or recent planet migration. This intense activity is further highlighted by detecting a star-size dust clump, passing in front of the star, in the midst of its infrared brightening. We constrain the minimum size and mass of the clump using multiwavelength transit profiles and conclude that the dust clump is most likely created by a large impact involving objects of several hundred kilometers in size with an apparent period of 142 days (i.e., 0.62 au, assuming a circular orbit). The system’s evolutionary state (right after the dispersal of its gas-rich disk) makes it extremely valuable to learn about the process of terrestrial-planet formation and planetary architecture through future observations.
