учитывая, что выбор оптимальной архитектуры беспроводной сети и ее параметров является сложной задачей, в данной статье рассматривается один из методов построения архитектуры ячеистой топологии, который предусматривает подключение к интернету устройств для обмена данными между собой и с другими системами, используя безопасные протоколы сетевой связи. Задача является актуальной, поскольку ее решение создает новые возможности для сбора и обработки данных, управления и автоматизации процессов, а также повышения удобства и комфорта жизни людей. Рассмотрено использование технологии беспроводных сетей. Проведено исследование с целью сравнения «классической» работы с датчиками в LAN и работы с использованием технологии MESH. Было создано приложение, работающее с мобильной группой узлов для отправки данных на агрегирующий их сервер, к которому будет подключаться нативное Android-приложение. В итоге проведенных исследований сделан вывод, что выбор между стандартным подключением датчиков к сети Wi-Fi и ячеистой топологией с использованием Mesh Wi-Fi зависит от конкретных потребностей и ограничений. Сравнение технологий беспроводных сетей проводилось по результатам работы приложения по мониторингу погодных условий. Данный проект позволит обеспечить бесперебойную работу приложения, позволяющего на базе сети Wi-Fi организовать систему мониторинга микроклимата заданных зон
considering that choosing the optimal architecture of a wireless network and its parameters is an extremely difficult task, this article discusses one of the methods for constructing a cellular network architecture, which provides for connecting devices to the Internet to exchange data between themselves and with other systems using secure network communication protocols. The task is relevant because its solution creates new opportunities for data collection and processing, management and automation of processes, as well as improving the convenience and comfort of people's lives. The use of wireless network technology is considered. A study was conducted to compare the "classical" work with sensors in LAN and work using MESH technology. An application was created that works with a mobile group of nodes to send data to an aggregating server, to which a native Android application will connect. As a result of the conducted research, it was concluded that the choice between a standard connection of sensors to a Wi-Fi network and a mesh topology using Mesh Wi-Fi depends on specific needs and limitations. The comparison of wireless network technologies was carried out based on the results of the weather monitoring application. This project will ensure the uninterrupted operation of the application, which allows organizing a microclimate monitoring system based on a Wi-Fi network from specified zones

показана возможность многопараметрической и, соответственно, многокритериальной многофазной оперативной комплексной оценки качества радиолинии метеорной связи на ультракоротких волнах, состоящая в том, что оперативная технологическая оценка качества высокочастотного аналогового канала связи должна быть выработана в течение нескольких микросекунд, а образовавшегося дискретного канала передачи данных ‒ в течение нескольких миллисекунд. Так как процесс многофазный, время выработки интегрального критерия о пригодности радиолинии метеорной связи к телекоммуникации и возможности её использования в инфотелекоммуникациях строго ограничено в каждой фазе этого процесса, поэтому оперативный технологический контроль и комплексная оценка качества позволяют выработать интегральную оценку за минимально возможное время с минимально возможной погрешностью. Предложен вариант структурно-функциональной схемы радиолинии метеорной связи на ультракоротких волнах, обеспечивающей фрагментацию-дефрагментацию потока передаваемых информационных данных. Также подробно рассмотрен такой из качественных показателей, как помехоустойчивость радиолинии, от которого непосредственно зависит пропускная способность канала, приведены соотношения, из которых следует, что вероятность ошибки при за­данной скорости передачи может быть уменьшена более чем на порядок или во столько же раз может быть увеличена средняя скорость передачи при заданной помехоустойчивости
the paper shows the possibility of multi-parameter and, consequently, multi-criteria multiphase rapid complex quality assessment of meteor radio communication line at ultra-short waves. It is that the operational technological quality assessment of the high-frequency analog communication channel should be worked out within a few microseconds, and the formed discrete data transmission channel – within a few milliseconds. As process is multiphase, time of development of integral criterion of suitability of meteor communication radio line for telecommunication and possibility of its use in infotelecommunication is strictly limited in each phase of this process, therefore operational technological control and comprehensive quality assessment allow to develop an integral assessment for the minimum possible time with the minimum possible error. The article proposes a variant of the structural and functional diagram of the meteor communication radio line on ultrashort waves, which provides fragmentation-defragmentation of the stream of transmitted information data. The authors also focus on such a qualitative parameter as noise immunity of radio line, which directly influences on the channel bandwidth, ratios are given, from which it follows that the probability of error at a given transmission rate can be reduced by more than an order of magnitude or the average transmission rate can be increased by the same number of times at a given interference immunity
DEVELOPMENT OF A HIGH-PERFORMANCE LDPC DECODER WITH PIPELINED DATA PROCESSING
Authors: Башкиров А.В. , Хорошайлова М.В. , Ципина К.Д. 
Published: July 2023

разработан эффективный алгоритм декодирования суммы произведений (MSPA), который не только сокращает задержку критического пути, но и улучшает использование аппаратных средств и пропускную способность декодера при сохранении погрешности алгоритма декодирования. Алгоритм min-sum (MS) и его варианты заменяют сложные вычисления контрольных узлов (CN) в SPA простыми операциями сложения и сравнения, но это приводит к потере производительности до 1 дБ по сравнению с SPA для более высоких длин кодовых слов, кодовых скоростей и степеней узла. Представлены три полностью параллельные архитектуры низкоплотностного декодера, основанные на структуре проекционной геометрии (PG) полей Галуа LDPC-кодов. Эти конструкции отличаются архитектурами битового узла (BN) и контрольного узла (CN). Схема 9-битного квантования с фиксированной точкой используется для достижения лучшей производительности при исправлении ошибок. Другим значительным вкладом этой работы является конвейеризация предлагаемых архитектур декодера для дальнейшего повышения общей пропускной способности. Эти параллельные и конвейерные архитектуры реализованы для 73-битных (скорость 0,616) и 1057-битовых (скорость 0,769) кодов PG-LDPC с регулярной структурой на программируемой логической интегральной схеме (ПЛИС) Xilinx Virtex-6 LX760. Предлагаемые конструкции также являются гибкими с точки зрения квантования, степени узла, коэффициента параллельности и длины кодового слова
this paper develops an efficient sum-of-products (MSPA) decoding algorithm that not only reduces the critical path delay, but also improves hardware utilization and decoder throughput while maintaining decoding algorithm error. The min-sum (MS) algorithm and its variants replace the complex control node (CN) calculations in SPA with simple addition and comparison operations, but this results in a performance loss of up to 1 dB compared to SPA for higher codeword lengths, code rates, and powers node. Three fully parallel low-density decoder architectures based on the projection geometry (PG) structure of the Galois fields of LDPC codes are presented. These designs differ in bit node (BN) and control node (CN) architectures. A 9-bit fixed-point quantization scheme is used to achieve better error correction performance. Another significant contribution of this work is the pipelining of proposed decoder architectures to further improve overall throughput. These parallel and pipelined architectures are implemented for 73-bit (rate 0.616) and 1057-bit (rate 0.769) regular structure PG-LDPC codes on the Xilinx Virtex-6 LX760 field-programmable logic integrated circuit (FPGA). The proposed designs are also flexible in terms of quantization, node degree, parallelism factor, and codeword length

Es importante destacar que el Desarrollo Infantil ha sido un tema visto durante décadas como no importante dentro del desarrollo de las sociedades más sin embargo luego de los estudios realizados por autores a nivel mundial, donde podemos citar bases conceptuales establecidas por Freud con su Teoría Psicoanalítica misma que cita ( Fernández,2018). Y desde un aspecto psicosocial se aborda a Erickson con sus etapas y las teorías del conductismo planteadas por autores como Skinner y Watson (Equipo editorial, 2021), por ende este proyecto de vinculación con la colectividad denominado Wawa Kuna Pugllan o en español los niños juegan identificó el Desarrollo Integral de los niños de 0 a 3 años en la comunidad beneficiaria, mismo que al conocer la realidad en la que se desenvuelven. Genera propuestas de actividades en procura del desarrollo de la niñez beneficiaria considerándola como un ente social capaz de aportar a su entorno.

Authors: Zapata Carnaqué Esperanza Marlene 
Published: July 2023

La investigación se centra en analizar y proponer cómo los Estados y las empresas privadas podrían integrar a aquellas personas que por diversas razones no son consideradas parte activa e importante de la sociedad. La inclusión se refiere a brindar igualdad de oportunidades y derechos a todas las personas, sin importar su origen o características individuales. La reinserción se enfoca en apoyar a aquellos que han estado fuera de la sociedad, como personas que han estado en prisión o han experimentado exclusión. Por otro lado, la resocialización implica adquirir habilidades y valores socialmente aceptados después de situaciones de marginación. En este estudio cualitativo basado en la revisión bibliográfica, se realizó una búsqueda exhaustiva de artículos relacionados con modelos de gestión empresarial para la inclusión, reinserción o resocialización de personas en situación de vulnerabilidad. Se seleccionaron los artículos relevantes y se llevó a cabo una revisión crítica de la literatura. Mediante el análisis temático, se identificaron los temas recurrentes y los patrones emergentes en la literatura revisada. Las conclusiones destacaron la importancia de la gestión empresarial para promover la inclusión y la resocialización, y se enfatizó la necesidad de construir una sociedad más inclusiva y solidaria.

Abstract
Using both ground-based transit photometry and high-precision radial velocity spectroscopy, we confirm the planetary nature of TOI-3785 b. This transiting Neptune orbits an M2-Dwarf star with a period of ∼4.67 days, a planetary radius of 5.14 ± 0.16 R

By increasing the number of confirmed planets, TOI-3785 b offers an opportunity to compare similar planets across varying planetary and stellar parameter spaces. Moreover, with a high-transmission spectroscopy metric of ∼150 combined with a relatively cool equilibrium temperature of T
eq = 582 ± 16 K and an inactive host star, TOI-3785 b is one of the more promising low-density M-dwarf Neptune targets for atmospheric follow up. Future investigation into atmospheric mass-loss rates of TOI-3785 b may yield new insights into the atmospheric evolution of these low-mass gas planets around M dwarfs.
XMM-Newton and Chandra Observations of the Candidate Fermi-LAT Pulsar 4FGL J1015.5-6030
Authors: Hare Jeremy , Kargaltsev Oleg , Younes George , Pavlov George G. , Volkov Igor 
Published: July 2023

Abstract
4FGL J1015.5-6030 is an unidentified Fermi-LAT source hosting a bright, extended X-ray source whose X-ray spectrum is consistent with that of a young pulsar, yet no pulsations have been found. Here we report on XMM-Newton timing and Chandra imaging observations of the X-ray counterpart of 4FGL J1015.5-6030. We find no significant periodicity from the source and place a 3σ upper limit on its pulsed fraction of 34%. The Chandra observations resolve the point source from the extended emission. We find that the point source’s spectrum is well fit by a blackbody model, with temperature kT = 0.205 ± 0.009 keV, plus a weak power-law component, which is consistent with a thermally emitting neutron star with a magnetospheric component. The extended emission spans angular scales of a few arcseconds up to about 30″ from the point source and its spectrum is well fit by a power-law model with a photon index Γ = 1.70 ± 0.05. The extended emission’s spectrum and 0.5–10 keV luminosity of 4 × 1032 erg s−1 (at a plausible distance of 2 kpc) are consistent with that of a pulsar wind nebula. Based on a comparison to other GeV and X-ray pulsars, we find that this putative pulsar is likely a middle-aged (i.e., τ ∼ 0.1–1 Myr) radio-quiet pulsar with

Nonthermal Emissions from a Head–Tail Radio Galaxy in 3D Magnetohydrodynamic Simulations
Authors: Ohmura Takumi , Asano Katsuaki , Nishiwaki Kosuke , Machida Mami , Sakemi Haruka 
Published: July 2023

Abstract
We present magnetohydrodynamic simulations of a jet–wind interaction in a galaxy cluster and the radio to gamma-ray and neutrino emissions from this “head–tail galaxy.” Our simulation follows the evolution of cosmic-ray (CR) particle spectra with energy losses and stochastic turbulence acceleration. We find that the reacceleration is essential to explaining the observed radio properties of head–tail galaxies, in which the radio flux and spectral index do not drastically change. Our models suggest that hard X-ray emissions can be detected around the head–tail galaxy in the Perseus cluster by hard X-ray satellites, such as FORCE, and they will potentially constrain the acceleration efficiency. We also explore the origin of the collimated synchrotron threads, which have been found in some head–tail galaxies by recent high-quality radio observations. Thin and elongated flux tubes, connecting the two tails, are formed by strong backflows at an early phase. We find that these threads advect with the wind for over 300 Myr without disruption. The radio flux from the flux tubes is much lower than the typical observed flux. An efficient CR diffusion process along the flux tubes, however, may solve this discrepancy.
Magnetar Flare-driven Bumpy Declining Light Curves in Hydrogen-poor Superluminous Supernovae

Published: July 2023

Abstract
Recent observations indicate that hydrogen-poor superluminous supernovae (SLSNe-I) often display bumpy declining light curves. However, the cause of these undulations remains unclear. In this paper, we have improved the magnetar model, which includes flare activities. We present a systematic analysis of a well-observed SLSN-I sample with bumpy light curves in their late phase. These SLSNe-I were identified from multiple transient surveys, such as the Pan-STARRS1 Medium Deep Survey and the Zwicky Transient Facility. Our study provides a set of magnetar-powered model light curve fits for five SLSNe-I, which accurately reproduce the observed light curves using reasonable physical parameters. By extracting the essential characteristics of both the explosions and central engines, these fits provide valuable insights into investigating their potential association with gamma-ray burst engines. We found that the SLSN flares tend to be the dim and long extension of GRB flares in the peak luminosity versus peak time plane. Conducting large-scale, high-cadence surveys in the near future could enhance our comprehension of both SLSN undulating light curve properties and their potential relationship with GRBs by modeling their light curve characteristics.
First record of the non-native Osbornellus auronitens (Provancher, 1889) (Hemiptera, Cicadellidae, Deltocephalinae) in Italy

Globalisation and international trade, in particular, are the major drivers of introduction and the spread of non-native species. To date, more than 30 species of non-native Hemiptera Auchenorrhyncha have been accidentally introduced into Europe. Some species are invasive with important repercussions primarily for agricultural activities, while almost no information exists on their impacts within natural ecosystems. Therefore, early detection of non-native species and their subsequent monitoring are extremely important actions to undertake.
The North American Osbornellus auronitens (Provancher, 1889), firstly recorded for the Palearctic and Europe in Switzerland in 2016, is recorded in Italy for the first time on the basis of 77 specimens collected between August 2015 and October 2022.

Published: July 2023

Le tribunal de Ṭalīt, dans le Fayoum méridional, n’était jusqu’ici connu qu’à partir d’un unique document remontant au début de la période fatimide. La présente contribution offre l’édition et la traduction de deux nouveaux documents, comportant en tout cinq textes qui permettent de mettre en évidence le fonctionnement de ce petit tribunal provincial présidé par un substitut, ainsi que son articulation aux échelons supérieurs et inférieurs du système judiciaire islamique. Le procès-verbal d’une audience (maḥḍar), une pétition de plaideur (qiṣṣa) et le rescrit (tawqīʿ) auquel celle‑ci donna lieu, projettent une lumière nouvelle sur les usages de l’écrit dans les tribunaux, surtout étudiés jusqu’ici à partir des sources littéraires. Enfin, à travers ces documents, transparaissent les stratégies successorales d’une famille de notables coptes du village de Ṭuṭūn/Tebtynis, les Banū Ǧirǧa, qui recoururent au tribunal islamique pour sanctionner des accords à l’amiable conformes à leurs coutumes.
Gallstone ileus: Unusual complication of cholelithiasis
Authors: Kao Kuo-Feng , Yu Ji-Kuen , Yu Suan-Hung , Wei Chih-Wei , Huang Tai-Lin 
Published: July 2023

Abstract
Gallstone ileus is an unusual complication of gallstone disease. However, gallstone ileus is a serious cause of mechanical bowel obstruction. Gallstone ileus affects older adult patients with underlying medical diseases. It occurs when a gallstone passes through a fistula between the gallbladder and small bowel before becoming obstructed at the ileocecal valve. The symptom includes episodic obstruction caused by the stone rolling through the bowel lumen. Gallstone impaction produces abdominal pain and vomiting, which subside as the gallstone becomes disimpacted, only to recur again as the stone lodges in the more distal bowel lumen. The mean symptom duration before the emergency department visit is approximately 5 days, similar to our patient. Computed tomography is widely used to confirm the diagnosis.
Percutaneous Coronary Intervention versus Coronary Artery Bypass Grafting in Complex Coronary Artery Disease
Authors: Hesse Kerrick , Egred Mohaned , Zaman Azfar , Alkhalil Mohammad , Farag Mohamed 
Published: July 2023

Background:
Clinical equipoise between a percutaneous coronary intervention (PCI) and coronary artery bypass grafting surgery (CABG) in the treatment of complex coronary artery disease (CAD), including unprotected left main coronary artery (LMCA) and/or three-vessel disease (3VD), remains debatable.

Methods:
A retrospective analysis of an unselected cohort undergoing contemporary PCI versus CABG at a large center in 2015. Patients who received nonemergent treatment of unprotected LMCA and/or 3VD were included. The primary study endpoint was all-cause mortality at 5 years. Secondary endpoints included a composite of all-cause mortality, spontaneous myocardial infarction (MI), or ischemia-driven repeat revascularization at 30 days and 1 year.

Results:
Four hundred and thirty patients met the inclusion criteria, 225 had PCI, and 205 had CABG. PCI patients were older with frequent LMCA involvement and higher EuroSCORE yet they had a fourfold shorter in-hospital stay compared to CABG patients. At 5 years, there was no significant difference in the primary endpoint between CABG and PCI (adjusted Hazard ratios 0.68, 95% confidence interval: 0.38–1.22, P = 0.19). Likewise, there was no significant difference in the incidence of the secondary composite endpoint or its components at 30 days or 1 year. A propensity score-matched analysis in 220 patients revealed similar outcomes.

Conclusions:
In real-world long-term contemporary data, survival after PCI was comparable to CABG at 5 years in patients with unprotected LMCA and/or 3VD. At 1 year, the incidence of spontaneous MI and ischemia-driven repeat revascularization did not differ between the two cohorts. The mode of revascularization in these complex patients should be guided by the heart team.
