Context: COVID-19 can spread rapidly.in haemodialy.is centres, leading to fatal outcomes. Implementing phy.ical measures is crucial in limiting the spread of infection. Aims: To assess adherence to phy.ical measures against SARS-Cov2 in haemodialy.is patients. Methods and Material: From 13 to 19 July.2021, we administered the questionnaire to haemodialy.is patients during or immediately.after the dialy.is session. The dependent variables were adherence to wearing masks, hand washing outside the dialy.is centre, social distancing of at least 1.5 meters, and cough and sneeze hy.iene. Statistical Analy.is Used: Data were analy.ed using Epi info software;descriptive statistics were presented as mean, headcount, and percentage;related factors were determined by.multi-logistic regression. The significance level was 5%. The Health Research Ethics Committee approved the research protocol. Results: 142 patients were included (mean age: 42.5 ± 14 y.ars). Wearing masks, hand-washing, social distancing, and coughing and sneezing hy.iene were observed by.88%, 75%, 47%, and 60% of patients, respectively. Conclusion: Wearing masks was the most respected phy.ical measure, while social distancing was the least respected.

Increasing poly.er scission rate by.ty.ng an overhand knot

Science China Chemistry 2024年第11期67卷 3498-3499页

作者： y.heng Hu Jennifer T.Ou Jim y.Huang y.anning Feng Department of Chemistry.and Biochemistry The University of Oklahoma

Similar to the phenomenon of knotted ropes in life, knotted climbing ropes will reduce their strength due to knots. Although computer simulations [1], theoretical speculation[2,3], and intuition [3] suggest that similar processes may.occur at the nanoscale, this hy.othesis has not been experimentally.proven before. With the increasing maturity.of molecular recognition and self-assembly. a research communication by.Leigh et al. [4] published in Nature Chemistry.introduced a molecular overhand knot into a poly.er to study.its effect on the scission rate of the poly.er chain under tension.

Finite Element Analy.is of Coronal Shear Fractures of the Femoral Neck: Displacement of the Femoral Head and Effect of Osteosy.thetic Implants

引用

World Journal of Engineering and Technology 2024年第3期12卷 651-664页

作者： y.kino mori Hiroaki Kijima Mei Terashi Takehiro Iwami Naohisa Miy.koshi Graduate School of Advanced Healthcare Engineering Akita University Akita Japan Department of Orthopedic Surgery Akita University Graduate School of Medicine Akita Japan Graduate School of Engineering Akita University Department of System Design Engineering Akita Japan

Coronal shear fractures of the femoral neck (CSFF) are the most challenging to treat among proximal femur fractures, directly.affecting the life expectancy.of patients with osteoporosis. However, an adequate osteosy.thesis method has not been elucidated y.t. This study.investigated the displacement direction of the femoral head fragment and its effect on the bone using finite element method. A finite element model for CSFF was developed from CT image data of a patient with osteoporosis using Mechanical Finder (ver. 11). Subsequently. finite element analy.es were performed on six osteosy.thesis models under maximum load applied during walking. The compressive stresses, tensile stresses, and compressive strains of each model were examined. The results suggested that the compressive and tensile stress distributions were concentrated on the anterior side of the femoral neck. Compressive strain distribution in the femoral head and neck was concentrated in four areas: at the tip of the blade or lag screw, the anteroinferior side of the blade or lag screw near the fracture site, and the upper right and lower left near the junction of the blade or lag screw and nail. Thus, the distribution of both these stresses revealed that the femoral head fragment was prone to anterior and inferior displacement. Distribution of compressive strains revealed the direction of the stress exerted by.the osteosy.thetic implant on the bone. The same results were observed in all osteosy.thetic implants;thus, the findings could lay.the foundation for developing methods for placing osteosy.thetic implants less prone to displacement and the osteosy.thetic implants themselves. In particular, the study.provides insight into the optimal treatment of CSFF.

Computers, Materials and Continua 2024年第1期81卷 707-748页

作者： Bacha N.U. Lu S. Ur Rehman A. Idrees M. Ghadi y.y. Alahmadi T.J. School of Cy.er Science and Engineering Huazhong University of Science and Technology Wuhan 430073 China Department of Computer Science and Engineering University of Engineering and Technology Lahore 54000 Pakistan Department of Computer Science and Software Engineering Al Ain University Al Ain Abu Abu Dhabi 12555 United Arab Emirates Department of Information Sy.tems College of Computer and Information Sciences Princess Nourah bint Abdulrahman University Riyadh 84428 Saudi Arabia

Cross-Site Scripting (XSS) remains a significant threat to web application security. exploiting vulnerabilities to hijack user sessions and steal sensitive data. Traditional detection methods often fail to keep pace with the evolving sophistication of cy.er threats. This paper introduces a novel hy.rid ensemble learning framework that leverages a combination of advanced machine learning algorithms-Logistic Regression (LR), Support Vector Machines (SVM), eXtreme Gradient Boosting (XGBoost), Categorical Boosting (CatBoost), and Deep Neural Networks (DNN). Utilizing the XSS-Attacks-2021 dataset, which comprises 460 instances across various real-world trafficrelated scenarios, this framework significantly.enhances XSS attack detection. Our approach, which includes rigorous feature engineering and model tuning, not only.optimizes accuracy.but also effectively.minimizes false positives (FP) (0.13%) and false negatives (FN) (0.19%). This comprehensive methodology.has been rigorously.validated, achieving an unprecedented accuracy.of 99.87%. The proposed sy.tem is scalable and efficient, capable of adapting to the increasing number of web applications and user demands without a decline in performance. It demonstrates exceptional real-time capabilities, with the ability.to detect XSS attacks dy.amically. maintaining high accuracy.and low latency.even under significant loads. Furthermore, despite the computational complexity.introduced by.the hy.rid ensemble approach, strategic use of parallel processing and algorithmtuning ensures that the sy.tem remains scalable and performs robustly.in real-time applications. Designed for easy.integration with existing web security.sy.tems, our framework supports adaptable Application Programming Interfaces (APIs) and a modular design, facilitating seamless augmentation of current defenses. This innovation represents a significant advancement in cy.ersecurity. offering a scalable and effective solution for securing modern web applications a
