Published: April 2024

Abstract. Degrading rock wall permafrost was found responsible for the increase in rockfall and landslide activity in several cold mountain regions across the globe. In Greenland, rock wall permafrost has so far received little attention from the scientific community, despite mountains being a predominant feature on the ice-free coastline and landslide activity being significant. In this study, we aim to make a first step towards a better understanding of rock wall permafrost in Greenland by modelling rock wall temperatures in the mountain area around the town of Sisimiut, which is 68° N on the west coast of Greenland. We first acquire rock surface temperature (RST) data for the period September 2020–September 2022 to model rock surface temperatures from weather forcing. The model is then applied to weather data from 1870 to 2022, generating rock surface temperatures to force transient heat transfer simulations over the same period. By extrapolating this method at the landscape scale, we obtain permafrost distribution maps and ad hoc simulations for complex topographies. Our model results are compared to temperature data from two lowland boreholes (100 m depth) and geophysical data describing frozen and unfrozen conditions across a mid-elevation mountain ridge. Finally, we use regional carbon pathway scenarios 2.6 and 8.5 to evaluate future evolution of rock wall temperatures until the end of the 21st century. Our data and simulation describe discontinuous permafrost distribution in rock walls up to roughly 400 m a.s.l. Future scenarios suggest a decline of deep frozen bodies up to 800 m a.s.l., i.e. the highest summits in the area. In summary, this study depicts a picture of warm permafrost in this area, highlighting its sensitivity to ongoing climate change.
Modeling Nonlinear Physical Systems in a Real-Time Operating System Environment for Control and Cyber Threat Mitigation
Authors: Prarthana A. Deshkar,  
Published: April 2024

Nonlinearity control and interconnection between physical systems are essential for many contemporary systems. Cyber Physical systems came about because of the growing number of security concerns with network control systems. Nonlinear physical systems are the primary subject of this study's investigation into control and cyber threat mitigation. Nonlinear physical systems are the focus of this study, which also delves into their control, modelling, and real-time implementation. Here, physical systems are defined as two kinds of benchmark nonlinear robotic systems: the Segway transporter and the cruise control system. Many see the Segway as an unstable and nonlinear physical system. By factoring in kinetic and potential energy, Lagrangian dynamics has allowed for the derivation of equations of motion. Next, a state-space model of the system is obtained by linearizing the nonlinear differential equations using Taylor series expansion of functions. This model is then transformed into two transfer functions, one for the tilt angle and one for the yaw angle. The Model Predictive Controller (MPC), GA Tuned PID, and PID are the building blocks of MATLAB's effective simulation study of nonlinear control.
FedCGS: Leverage Feature Compression and Conditional GAN for Privacy Protection and Efficient Communication in Federated Learning
Authors: Sun Haoxuan 
Published: April 2024

Federated learning is a distributed machine learning technique that can train models from decentralized data, collaboratively building central models and protecting data privacy by passing partial model updates rather than raw data in each iteration of model learning. However, recent work has shown that the information during the exchange between the server and the client is still vulnerable to gradient-based privacy attacks, and traditional privacy protection methods can incur significant costs (such as communication consumption and performance evaluation). Therefore, we need an algorithm that can protect data privacy while reducing communication costs and performance losses. Here, we propose a federated learning framework FedCGS that leverages conditional generation adversarial networks and feature compression in order to achieve privacy protection while maintaining competitive model performance and effectively improving communication efficiency. We divided the local network of each client into feature extractor and public classifier, and kept the extractor local to protect privacy, and sent classifier and client generator to the server for aggregation and update through singular value decomposition, so as to improve the performance of the local network and efficient communication. A lot of experimental data prove that FedCGS can improve the performance of local model better than traditional federation learning, and improve the communication efficiency better than common conditional generation adversarial network. Therefore, we believe that FedCGS has better federal learning potential
From Princess to Public University: The Augusta Sophia Collection of English Drama
Authors: Keener Andrew S. 
Published: April 2024

ABSTRACT
This article argues that a collection of English play-texts gathered by Princess Augusta Sophia of the United Kingdom (1768–1840), daughter of King George III (1738–1820) and Queen Charlotte (1744–1818), represents the royal family’s intergenerational tradition of women’s book collecting. Located today at the University of North Carolina at Charlotte, the collection comprises nearly eight hundred full texts of comedies, farces, and musical dramas, mostly from the long eighteenth century. Significantly, it reflects the royal family’s theatrical and book-collecting interests, particularly those of Queen Charlotte, who supervised the princess’s education and whose own books Augusta adopted after the monarch’s death. Tracing the library’s reorganization and movements toward a city named after the queen—Charlotte, North Carolina—this article additionally demonstrates how Augusta Sophia’s book-collecting legacy, and her mother’s, have been obscured by patrilineal libraries and academic research priorities, and also what steps might “reconstruct” her library for further inquiry.

Yellow tea belongs to specialty tea, and it is loved by consumers because of its unique flavor and taste. Herein, Pingyang Yellow Soup (PYS, a kind of yellow tea) was chosen. In this study, we investigated the effects of PYS on the hypoglycemic effect of the zebrafish model and explored its potential mechanism of action. Results showed that PYS had very strong and definite hypoglycemic biological activity. Meanwhile, different water/material ratios, extraction temperatures, and extraction times had significant influence on the hypoglycemic performance of PYS, and the strength of influence was ranked as extraction temperature > extraction time > water/material ratio. In addition, results showed that the removal rate of tea polyphenols (TPs) in PYS had a strong linear correlation to the degree of decreased hypoglycemic performance, indicating the hypoglycemic performance was closely related to TPs levels. The comprehensive analysis revealed that the nor-sugar rate of PYS had a variety of regression relationships with its components, and the best hypoglycemic performance does not require the highest content levels of each component but depends on what it is, and there exists a relative optimal value, which provides basic information for exploring the internal mechanism of action of hypoglycemic effects and developing functional tea drinks of PYS.
RESEARCH OF THE PHYSICAL PROPERTIES OF MULTI-COMPONENT, MULTILAYER, SOLID NANOCOMPOSITE COATINGS
Authors: Kasymbaev A. , Plotnikov S. V. , Turlybekuly A. , Pogrebnyak A. 
Published: April 2024

The results of studies of the physical and mechanical properties of nitride and carbide multilayer systems based on ((TiZrNbTa)N, depending on the methods of deposition and heat treatment are analyzed and summarized. The coatings were deposited by magnetron sputtering. Studies of the original and processed alloy samples were carried out in a regional engineering laboratory. When extremely high doses of N+ ions (1018 cm-2) are introduced into nanostructured coatings (TiZrNbTa)N, a multilayer structure is formed, consisting of amorphous, nanocrystalline (dispersed) and nanostructured layers.The hardness of the coatings decreases to 12 GPa in the near-surface region, and then increases with depth, reaching a maximum of 23 GPa at great depths ≥ 200 nm.Sputtering a small layer of the coating surface, leading to the elimination of the droplet fraction formed during cathode erosion during vacuum-arc sputtering, is the reason for the decrease in the microhardness of the implanted samples.
Early Palisaded Villages in Southwestern Ontario

Published: April 2024

Abstract
We review the initiation of palisade enclosed village communities in central southwestern Ontario, using data from a series of related early Late Woodland sites that we interpret as showing an east to west settlement sequence. New AMS dates based on samples of carbonized maize provide a revised chronology for the origin of village life, which began in the twelfth century. We show how villages developed alongside community pattern and ceramic attribute trends into the fourteenth-century middle Late Woodland period. A suite of dates from the most westerly site in the sequence on the Norfolk sand plain document the timing of an abrupt change in community pattern during the late fourteenth century.

Background: Acid peptic disorder (APD) is the most frequently encountered provisional diagnosis in general practice with Helicobacter pylori being the major causal agent. In the present study we aim to report the incidence of H. pylori infection among patients undergoing upper gastrointestinal endoscopy at a tertiary care center in central Nepal.
Methods: A hospital-based cross-sectional study was conducted among 101 patients with diagnosis of APD. An Upper gastrointestinal (UGI) Endoscopy was performed on all the participants and biopsy specimen was obtained from various parts depending on the endoscopic findings. Reports of H&E stain H. pylori status was recorded using a pre-formed proforma. Data analysis was done using SPSS-20.
Results: H. pylori infection was found in 41.6% (42/101) patients with female predominance (25/60) (59.5%). Both married men and women had higher prevalence of HP infection than their unmarried counterparts. Patients with blood group O were found to be the most affected.
Conclusions: A higher prevalence of H. pylori was found among APD patients who had undergone upper gastrointestinal endoscopy.

Published: April 2024

Background: Surgical Antimicrobial Prophylaxis is administration of a short course of antimicrobial agent prior to surgery. It has long been recommended for routine use in preventing occurrence of surgical site infections. The choice of drug, dosage, route, duration and timing of antimicrobial prophylaxis has been specified in the clinical practice guideline issued by American Society of Health-System Pharmacists. In the present study, we aim to seek the practice of antibiotic prophylaxis at a tertiary care centre in central Nepal and report the adherence to American and National Antimicrobial Treatment Guideline where applicable.
Methods: This hospital-based cross-sectional study was conducted between January to June 2023 among 232 patients undergoing surgery at Chitwan Medical College Teaching Hospital. Data collection tool prepared with slight modification from previous studies recorded the demographic details, surgical data, surgical antimicrobial prophylaxis usage data and assessment of Prophylaxis data. Data analysis was done using SPSS-20.
Results: We observed compliance to selection of drug, route of administration, dosage of antimicrobial prophylaxis with American guideline. All (100%) prophylaxis was administered parenterally for more than 72 hours in over 40% cases. Choice of drug was appropriate in over 84% of cases and dosage adequacy was observed in over 61% cases. Surgical antimicrobial prophylaxis was administered most frequently 30 minutes before surgery (52.59%).
Conclusions: All the surgical patients were found to receive surgical antimicrobial prophylaxis. Ceftriaxone was the most commonly administered drug followed by combination of piperacillin and tazobactam. The duration of treatment post-surgery was found to be unnecessarily broader than recommended guideline.

Authors: Đông Trần Phước , Tâm Nguyễn 
Published: April 2024

Tường bê tông chịu lực đúc sẵn (hay còn được gọi là Tường bê tông tấm lớn - Concrete Load Bearing Precast Panels) được ứng dụng tại nhiều nơi trên thế giới. Tuy nhiên việc ứng dụng trong các tòa nhà cao tầng (lên đến 70 tầng) chỉ mới được ứng dụng gần đây. Australia là nước tiên phong trong ứng dụng giải pháp này trên thế giới cho các công trình chung cư cao tầng. Trong nghiên cứu này chúng tôi muốn đưa giải pháp này vào thay thế việc xây dựng chung cư cao tầng với giải pháp đổ tại chỗ truyền thống bằng tường bê tông chịu lực đúc sẵn. Bằng cách này chúng tôi thay đổi cách giải quyết bài toán kết cấu của toàn bộ công trình từ phần thân đến phần móng. Biện pháp thi công cũng như thời gian thi công sẽ được cải tiến đáng kể. Chi phí và độ bền vững của công trình cũng là ưu điểm lớn của nó. Việc ứng dụng precast panels sẽ giúp chúng ta có thể đầu tư xây dựng các chung cư cao tầng ở với số lượng lớn với giá thành rẽ đạt tiêu chí « nhanh, rẽ, đẹp, bền ». Nghiên cứu này áp dụng một case study ở Việt Nam cho một công trình chung cư được thiết kế và thi công hoàn toàn bằng precast panels vừa là cấu kiện chịu tải trọng đứng và ngang vừa là tường bao che (architectural façade) của công trình. Thiết kế đã chứng minh được hệ kết cấu đảm bảo an toàn chịu lực và đáp ứng được các tiêu chuẩn của Việt Nam và Australia với giá thành thấp hơn phương pháp đổ tại chỗ.
