Published: June 2024

ABSTRACTS Bone cysts of the talar body are a benign, rare condition. Remove bone cysts, autologous bone grafting is a treatment method many authors recognize. Approaching the calcaneal bone cysts of the talar body encounters difficulties due to the narrow surgical field, poor blood supply, and the entire surface of the talar body being covered with cartilage. Endoscopic talar joint surgery to remove cysts bone, autologous bone grafting in the treatment of calcaneal bone cysts of the talar body is a progressive step, with many advantages, overcoming the mentioned difficulties, albeit being a challenging technique. We report a case of bone cysts of the talar body treated with endoscopic ankle joint surgery to remove cysts bone and autologous bone grafting at Viet Duc University Hospital, with good postoperative results, and no recurrence after 8 months of follow-up.

Authors: Shaty Wahby 
Published: June 2024

Background Dega osteotomy is becoming more widely used for the treatment of developmental dysplasia of the hip (DDH). Objective A thorough description of this procedure is needed as many of the technical aspects are not fully defined. Moreover, more follow-up series are also needed to evaluate its outcomes. Methods In this study, we gave a detailed anatomic description for this procedure and also presented our experience as a retrospective radiographic and case-note study. We examined the clinical and radiographic records of 44 patients (48 hips) with varying degrees of DDH. Results The average age of the patients was 2 months and 7 months while the average follow up period was 41 months. Clinical and radiographic assessment including CT with 3D reconstruction to examine the anatomic characteristics of the osteotomy were undertaken. We found that concentric reduction was achieved in 93.7% with excellent clinical and radiographic outcomes. Only 3 cases needed revision of the Dega osteotomy. The re-operation rate was 12.5%. CT scan revealed that the arcuate line was crossed by the osteotomy in the majority of cases. In 20.7% of cases, a bone cut that was intended to be a Dega osteotomy was found to have been inadvertently implemented as another osteotomy variant. However, this bore no significant effect on the outcome. Conclusion We found that a well-implemented Dega osteotomy is a reliable tool to cope with the acetabular changes in DDH.

Abstract
The emergence of generative artificial intelligence (AI), exemplified by models like ChatGPT, presents both opportunities and challenges. As these technologies become increasingly integrated into various aspects of society, the need for a harmonized legal framework to address the associated risks becomes crucial. This article presents a comprehensive analysis of the disruptive impact of generative AI, the legal risks of AI-generated content, and the governance strategies needed to strike a balance between innovation and regulation. Employing a three-pronged methodology—literature review, doctrinal legal analysis, and case study integration—the study examines the current legal landscape; synthesizes scholarly works on the technological, ethical, and socioeconomic implications of generative AI; and illustrates practical challenges through real-world case studies. The article assesses the strengths and limitations of US governance strategies for AI and proposes a harmonized legal framework emphasizing international collaboration, proactive legislation, and the establishment of a dedicated regulatory body. By engaging diverse stakeholders and identifying critical gaps in current research, the study contributes to the development of a legal framework that upholds ethical principles, protects individual rights, and fosters responsible innovation in the age of generative AI.

Eryngium aquaticum L. (Apiaceae), a culinary herb enjoyed in global cuisines, is also valued for its medicinal properties. The essential oil (EO) extracted from E. aquaticum leaves by hydro-distillation was subjected to antibacterial and antibiofilm activity using a microtiter plate-based in vitro assay against Staphylococcus aureus and Pseudomonas aeruginosa. Compounds identified by GC-MS analysis of EO were screened against the transcriptional regulatory proteins SarA of S. aureus and LasR of P. aeruginosa by molecular docking analysis. The minimum inhibitory concentration (MIC) was recorded as 250 μg/mL against both of these two pathogens. The EO of E. aquaticum also showed concentration-dependent antibiofilm activity against these pathogens, with a maximum inhibition of 50.9 and 48.03% against P. aeruginosa and S. aureus, respectively, at the highest concentration (500 μg/mL) tested. The GC-MS analysis identified 17 compounds and all of them showed moderate to weak binding affinity for the active sites of SarA and LasR, with pentanedioic acid (2,4-di-t-butylphenyl) mono-ester showing the best docking score against SarA (-5.7 kcal/mol) and LasR (-8.0 kcal/mol). This study suggests that E. aquaticum can be a good source of EO with antibacterial and antibiofilm activity against P. aeruginosa and S. aureus.

Authors: Wahiduzzaman Mohammad , Gour Chandra Paul  
Published: June 2024

Employing a non-central difference method of lines in tandem with the 4th order Runge-Kutta technique, this study adopts a sophisticated computational approach, ensuring precision and efficiency to resolve the shallow water equations and predict water levels caused by a cyclone in the coastal area of Bangladesh. To discretize spatial derivatives, a 4-point backward finite difference method utilized while keeping time derivatives continuous. The authors transformed the shallow water equations with boundary conditions into an initial value problem and used the Runge-Kutta(4,4) method for solving this transformed initial value problem. To effectively include the land-sea boundary and bottom structure at a reasonable charge, the authors used a high-resolution approach. To create a regular and stable tidal oscillation in the area, the authors applied the tidal component to the southern boundary of the primary model. Then ran the surge model to estimate water elevations caused by the nonlinear interaction between tide and surge. Using numerical experiments, the authors simulated water heights generated by tide, pure surge, and tide surge interaction caused by the intense cyclonic storm SITRANG. The study's simulated results demonstrate a commendable alignment with the reported data.

Published: July 2024

Image J system was used to process the different images of Ostracoda. As this system is considered one of the modern and advanced computer systems used in image processing. Image processing is one of the main branches of computer science and has developed in the current era as a result of the amazing development in computer and communication technologies. Micropaleontology is the systematic study of the morphology and classification of the microscopic fossils and their ecological, and stratigraphic importance. A microscope is the greatest tool for studying a microfossil's distinctive features because it is often tiny. Images of the Ostracoda were taken from the city of Duhok in Iraqi Kurdistan, from the Kolosh Formation, in which these species were studied and diagnosed. Seven species of ostracoda were obtained: Gujaratella sp. ,Acanthocythereis hystrix , Alocopocythere gujaratensis , Alocopocythere sp.1, Alocopocythere fossularis Keijella sp.1 and Sulcostocythere sp.1 The size of the original image was found and many manipulations and calculations were made, including finding the edges of the image, finding the length, height, area, perimeter and mean of the ostracoda image, and drawing the histogram of the original image. These calculations help in processing and analyzing images. This helps to shorten the time and effort of researchers in the field of geology.

Published: June 2024

Bidirectional radio over fiber (RoF) transmission to multiple remote antenna units (RAUs) with frequency octupling is proposed in this paper. The proposed RoF system uses a dual-port Mach-Zehnder modulator (DP-MZM) and an arrayed waveguide grating (AWG) to generate millimeter-wave (mm-wave) to four different RAUs. Bit Error Rate (BER) and received optical power are key parameters used to measure the performance of the system. From the simulation results, it is shown that the proposed system achieves an acceptable performance a fiber distance of 50 km with a BER of 10-12. Furthermore, the results indicate that the dispersion-induced power penalties for both uplink and downlink transmission of all RAUs are less than 1 dB. In summary, the proposed system simplifies the RoF system by reusing wavelengths and utilizing low RoF frequency through the frequency-octupling technique.

Стаття присвячена розробці та апробації аналітичного інструментарію, що має поліпшити чутливість поширених методів оцінювання динаміки добробуту домогосподарств до змін у структурі їхніх споживчих видатків. Для цього запропоновано використовувати концепцію компенсаційної варіації доходу (споживчого бюджету) та підхід Слуцького до графічного моделювання й формального вираження розмірів компенсаційної варіації. Застосування розробленого інструментарію для оцінювання динаміки добробуту домогосподарств України за період 2014-2021 рр. дозволило уточнити характер розподілу інфляційного тиску між домогосподарствами з різним рівнем доходу. Було виділені групи домогосподарств, що через специфічну структуру своїх споживчих видатків (їх високу сконцентрованість на товарах і послугах першої необхідності, ціни на які зростають швидше, ніж агрегований індекс споживчих цін за всіма товарними групами) опиняються в становищі «аутсайдерів» та стикаються з нестачею зростання номінальних доходів навіть для того, щоб зберегти обсяги споживання (економічний добробут) на рівні базового періоду. Апробація запропонованого інструментарію підтвердила його аналітичний потенціал, зокрема щодо виділення внеску окремих товарних груп у динаміку добробуту домогосподарств і уточнення характеру залежності між рівнем доходу домогосподарств і темпами зростання їхнього економічного добробуту.
