Published: February 2024

Introduction: Glaucoma is a leading cause of irreversible blindness, and implantation of drainage devices is an effective treatment option for patients with advanced glaucoma. The purpose of this study was to investigate the success rate of glaucoma drainage devices implantation in Kariadi Hospital.
Methods: This was an observational analytic study with a retrospective design. All patients who received Virna implantation between January 2020 and December 2022 were included. Intraocular pressure (IOP) examination was performed at the baseline and at the first day, at the seventh day, at the first month, and at the third month after surgery. The success rate was divided into three groups: complete success if IOP was <21mmHg without medication, qualified success if IOP was <21mmHg with medication, and failure if IOP was >21mmHg with medication.
Results: This study included 42 patients (42 eyes) with an average age of 43.3 years. There were 16 male (38%) and 26 female (62%) patients in the group. From these patients, 11 (26.2%) had primary glaucoma and 31 (73.8%) had secondary glaucoma. There was a significant decrease in IOP from preoperative measurement (37.1±10.1mmHg) compared to IOP on the first day (13.0±6.0mmHg), on the seventh day (15.4±3.8mmHg), on the first month (18.2±4.4mmHg), and on the third month (23.4±8.9mmHg) after surgery (p<0.05). At three-month follow-up, the complete success was 14.29%, the qualified success was 50%, and the failure was 35.71%.
Conclusion: Glaucoma drainage device implantation was found to successfully reduce IOP in patients with advanced glaucoma. The qualified success rate was higher than complete success rate, suggesting that some patients may require medication to achieve target IOP levels.
Design methodology of compact edge vision transformer CiM considering non-volatile memory bit precision and memory error tolerance

Published: February 2024

This paper proposes a design methodology for a compact edge vision transformer (ViT) Computation-in-Memory (CiM). ViT has attracted much attention for its high inference accuracy. However, to achieve high inference accuracy, the conventional ViT requires fine-tuning many parameters with pre-trained models on large datasets and a large number of matrix multiplications in inference. Thus, to map ViT to non-volatile memory (NVM)-based CiM compactly for edge applications (IoT/Mobile devices) in inference, this paper analyses fine-tuning in training, clipping, and quantization in inference. The proposed compact edge ViT CiM can be optimized by three design methods according to use cases considering the required fine-tuning time, ease of setting memory bit precision, and memory error tolerance of ViT CiM. As a result, in CIFAR-10, the most compact type successfully reduces the total memory size of ViT by 85.8% compared with the conventional ViT. Furthermore, the high accuracy type and high error-tolerant type improve inference accuracy by 4.4% and memory-error tolerance by more than four times compared with convolutional neural networks, respectively.

Authors: Fan Jiawei , Xu Ruifeng , Arai Masakazu , Miyamoto Yasuyuki
Published: February 2024

The regrowth conditions for lateral tunnel FETs featuring heterojunctions involve a tradeoff between selective growth and heavy doping. This study mitigated the connection between single crystals on the InP layer and polycrystals on the SiO2 mask by significantly increasing the thickness of the SiO2 mask to surpass that of the growing GaAsSb layer. We successfully fabricated p-GaAsSb/i-InGaAs tunnel FETs using a thick SiO2 mask, wherein the carrier concentration of the p-GaAsSb source was 5 × 1019 cm−3, and the growth temperature was maintained at 500 °C. The observed current–voltage (I–V) characteristics exhibited an on/off ratio of 5 × 104 and demonstrated ambipolar current behavior, confirming the presence of a p-type source. However, the observed subthreshold swing (SS) was limited to 120 mV dec−1. In comparison with the I–V characteristics of the planar transistor, degradation of SS can be explained by interface state, and the factor that characterizes the change of the drain current with the surface potential

Published: February 2024

Two metal-induced lateral crystallization (MILC) methods are proposed as candidate techniques to enhance cell current in future ultra-high-density NAND-type 3D flash memory devices. The channel crystallinity differs depending on the MILC method. In a single MILC, the channel is composed of single-crystal Si, whereas in a regional MILC, the channel comprises multiple crystal grains that are larger than those of the conventional polycrystalline Si. Using transmission electron microscopy, the inhibiting factor of MILC was modeled to reveal that the two MILC approaches result in different cell current distributions that are related to their degree of crystallinity. A comparison of these two cell current distributions in a 3D flash memory with over 900 word-line stacks showed that the single MILC delivers a higher median cell current with outliers on the lower side. In contrast, the regional MILC delivers a lower median cell current without outliers on the lower side.

Analytic Approach to the Non-Preemptive Markovian Priority Queue
Authors: Zuk Josef , Kirszenblat David
Published: February 2024

A new approach is developed for the joint queue-length distribution of the two-level non-preemptive Markovian priority queue that allows explicit and exact results to be obtained. Marginal distributions are derived for the general multi-level problem. The results are based on a representation of the joint queue-length probability mass function as a single-variable complex contour integral, that reduces to a real integral on a finite interval arising from a cut on the real axis. Both numerical quadrature rules and exact finite sums, involving Legendre polynomials and their generalization, are presented for the joint and marginal distributions. A high level of accuracy is demonstrated across the entire ergodic region. Relationships are established with the waiting-time distributions. Asymptotic behaviour in the large queue-length regime is extracted.

Published: February 2024

Jelen írásban egy szokatlan leletről, egy csípőficamos tehén maradványairól számolunk be Baracs–Boldogdűlő római (2–3. századi) lelőhelyről. Az ilyen elváltozás régészeti anyagban igen ritka, a lelet Magyarországon egyedülálló. A baracsi példány talán tejelő tehén lehetett, és a sérülés után még hónapokig vagy akár évekig élt, bár fizikai munkára és ellésre már bizonyára alkalmatlan volt. A lelet bepillantást enged a sérült állatok korabeli ellátásának lehetőségeibe is: antik írásos források említést tesznek az ilyen sérülések kezelési módjairól.

Published: February 2024

Com o avanço tecnológico cada vez mais acentuado na ciência, a implantodontia caminha em busca de soluções mais adequadas que objetivam a melhora da qualidade de vida dos pacientes. Hodiernamente, a reabilitação total de maxilas edêntulas com perda óssea e atrofia maxilar têm sido um desafio em muitos dos casos, e visando evitar o uso de enxertos, reduzir o tempo de tratamento e suprir as expectativas do paciente o protocolo “All-on-four”, com o auxílio da cirurgia guiada, vêm se mostrando uma excelente alternativa para esses casos. O protocolo All-on-four é um método que consiste na colocação de quatro implantes com carga imediata, fundando-se no princípio de quatro implantes mais longos proporcionando uma estabilidade primária sem que haja a necessidade de se utilizar qualquer tipo de enxerto. Este estudo teve o objetivo de relatar um caso de reabilitação oral total maxilar por meio de implantes dentários pela técnica All-on-four associada à cirurgia guiada, com o intuito de avaliar suas características e contraindicações, destacando as vantagens e desvantagens da utilização da mesma. A paciente em questão foi avaliada criteriosamente, sendo levado em consideração sua queixa  principal e suas condições clínicas. Mediante planejamento digital do software implantviewer (Brasil), notou-se a possibilidade de realizar a instalação dos implantes dentários através da técnica All-on-four. Em primeira etapa, foi realizado o escaneamento para a confecção do guia cirúrgico, em seguida a cirurgia foi executada e o guia foi fixado na região com o auxílio dos pinos de fixação. O planejamento, principalmente por conta da cirurgia sem retalhos, proporcionou maior precisão e menor tempo cirúrgico. Após 48 horas da cirurgia foi instalada a prótese provisória e a função mastigatória estabelecida. A paciente vem sendo acompanhada há um ano, desde a instalação da prótese definitiva, encontra-se com a estética adequada e função mastigatória restabelecida. Conclui-se que essa técnica pode ser uma grande aliada na reabilitação de casos complexos, dentro dos limites do presente relato de caso.

Published: February 2024

Este estudo aborda os desafios enfrentados na prevenção do tromboembolismo venoso (TEV) em gestantes e no período pós-parto, destacando os fatores de risco e estratégias de intervenção. Durante a gravidez, o corpo da mulher passa por adaptações para acomodar o feto, aumentando o risco de formação de coágulos sanguíneos nas veias, que podem levar a complicações graves, como a gangrena venosa. Apesar dos avanços médicos, o TEV tornou-se a principal causa de mortalidade materna em locais onde outras causas foram controladas. O risco de TEV durante a gravidez e no período pós-parto é significativamente aumentado, sendo de cinco a dez vezes maior durante a gestação e até 20 vezes no pós-parto, comparado com mulheres não grávidas da mesma faixa etária. Fatores como idade avançada, obesidade, histórico familiar de TEV, trombofilias, gestações múltiplas, parto cesáreo e imobilidade prolongada contribuem para esse risco elevado. A revisão integrativa da literatura identificou que o uso de meias elásticas de compressão pode ser eficaz na redução do risco de TEV em mulheres grávidas, assim como o uso de anticoagulantes farmacológicos, como a heparina de baixa dose. Recomenda-se a avaliação sistemática dos fatores de risco para TEV em todas as gestantes e mulheres no período pós-parto, juntamente com a implementação de medidas preventivas apropriadas. Em resumo, o estudo ressalta a importância da identificação precoce e do manejo dos fatores de risco para TEV em gestantes e no período pós-parto, assim como da implementação de estratégias preventivas eficazes. Essas medidas têm o potencial de melhorar significativamente os desfechos maternos e neonatais, evidenciando a necessidade de uma abordagem multidisciplinar e individualizada na prevenção do TEV durante a gravidez e o pós-parto.

Authors:   Magomedov M.H. Yakovlev A.V.
Published: February 2024

If it is impossible to directly control the movement of a heavily loaded mechanical system with a limited power source of energy (HM-motor) under the condition of a force-torque uncertainty of the medium, it is shown that an effective solution to this problem is the transition to robust control, the technical implementation of which is achieved by embedding a gearbox-variator in the control system, which is one of the modern modifications of the classic Archimedes’ lever.
Keywords: source of limited mechanical power, force-torque uncertainty, force-torque robustness, inherent robustness, mechanical characteristic, gearbox-variator, power sources, robustness index, dynamic self-levelling, d'Alembert's principle, Archimedes' lever equation.

A solution to the problem of longitudinal impact of a slider with a punch on a forging for an impact press is obtained by the finite difference method. An algorithm for calculating the maximum deformations and stresses of an elastic polyurethane bushing when a self-restoring fuse is triggered by force for a КД2124 crank press with a force of 250 kN is presented. The resulting solution can be used to develop a concept for constructing a means of protecting impact crank presses from technological overloads.

Published: February 2024

The main results of improving in the condition of the surface layer of the working rolls of the training mill with their joint rotation pressed against each other in a state without a trained strip, are considered in order to further minimize changes in the roughness parameters of the trained strip from roll to roll. The analysis of changes in the roughness parameters of the working rolls during their running-in as a result of the elastic-plastic interaction of the microsteps of their surfaces is carried out. Mathematical dependences are obtained for calculating of the roughness parameters of the working rolls during their idle running in the stand, taking into account the ergodicity function of the process. It is shown that the permissible degree of reduction of the height parameters of the rough layer of the working rolls before stabilization during their running is determined by contact loads, physical and mechanical properties of the material of the rolls, the initial parameters of the microgeometry of their surfaces and friction conditions, and the time to stabilize of the roughness parameters depends mainly on the contact load and the speed of running-in, decreasing with decreasing load and increasing speed. It is determined that the maximum possible reduction in the initial roughness of the roll treated with shot after idle running them in a stand with a coefficient of friction of 0.3 is on average 57 %. A further change in roughness is associated with the effect of wear of the rough layer during the training of a cold-rolled strip. The obtained mathematical dependencies allow you to assign processing parameters, such as the compression force of the rolls, the speed or at a given speed — the running-in time.

Published: February 2024

The research investigates the effect of liquid boriding on the microstructure, composition and microhardness of the surface layer on 5KhNM and 3Kh2V8F die steels. Boriding was carried out for 8 hours at 850 and 1000 °С in a melt based on sodium tetraborate and sodium salts. After high-temperature exposure during the boriding process, the samples were quenched in oil and tempered. Next, the samples were subjected to metallographic, X-ray spectral, X-ray diffraction and durometric analyses. As a result of processing, boride diffusion layers were obtained on the surface of 5KhNM and 3Kh2V8F steels up to 100 and 130 μm thick, respectively. It has been established that iron borides Fe2B and FeB are formed on the surface of both steels. In addition, chromium boride CrB is additionally formed on the surface of 5KhNM steel, increasing the maximum microhardness of the layer to 2130 HV. The maximum microhardness of 3Kh2V8F steel reaches 1709 HV due to the formation of borides and carbides in the layer. A study of the surface topography after boriding showed that the roughness parameter Ra of 5KhNM steel increased by 1.87 times, and of 3Kh2V8F steel by 1.78 times compared to the initial state.

Authors: Музакаева Х.С. , Дускаев М.З.
Published: February 2024

Láurusnóbilis – это лекарственное растение, представляющее собой деревце или кустарник рода Лавр (Laurus) и семейства Лавровые (Lauraceae). Лекарственным сырьем этого растения являются листья. Laurusnobilis – одно из целебных растений, улучшающих функцию инсулина, связывая его с рецепторами на мембране, но влияние на людей не установлено. В связи с этим нами была поставлена цель - определить, может ли данное растение быть использовано для предотвращения или облегчения сахарного диабета 2 типа. Нами были исследованы 40 человек с диабетом 2 типа, которых разбили на 3 группы. Трем опытным группам дали пить каждый день отвары, приготовленные из листьев Laurusnobilis, содержащие 10, 5 или 2 г лекарственного сырья в течение 30 дней. Все три уровня лаврового листа снижали уровень глюкозы в сыворотке со значительным снижением от 20 до 25% через 30 дней. В контрольной группе существенных изменений не произошло. Таким образом, это исследование показывает, что потребление лаврового листа в дозе от 2 до 10 г/500 мл воды в день в течение 30 дней минимизирует риск развития диабета 2 типа.
