The red palm weevil （RPW） Rhynchophorusferrugineus is one of the most invasive insect pests causing massive damage on date palms over the world. Synthetic pyrethroid insecticide beta-cyfluthrin has been evaluated against developmental stages of RPW under laboratory conditions. These stages were exposed to residual film of the insecticide on transparent cups using a Potter precision laboratory spray tower. Percent mortality of males and females were recorded 0.5, 2.0 and 24 h after treatment. Furthermore, date palm offshoots were infested in mesh house, two months later, offshoots treated with 300 ppm （p.g/mL） beta-eyfluthrin using two methods dipping and injection. Bioassay test showed beta-cyfluthrin at 300 ppm caused 86,7% and 93,3% mortality against males and females after 2 h respectively with LC50 135.74 and 109.4 ppm. By increasing the concentration at 400 ppm, mortality reached 100% against males and females after 24 h, Developmental stages, eggs and larvae were more sensitive toward the insecticide, where at 120 ppm no eggs hatched after 96 h and 86.7% mortality was recorded at 200 ppm against larvae after 30 rain with LC50 93.19 ppm. In addition, dipping method of date palm offshoots in 300 ppm beta-cyfluthrin was a very convenient way to control all RPW stages compared to injection method. So, it possible to recommend this method for treating the date palm offshoots in such insecticide as one of the most important elements of integrated pest management for standardizing insecticide based quarantine protocols.

Case Reports in Clinical Medicine 2024年第5期13卷 187-192页

作者： Mishal al Mebayadh Rahaf aldawish Sohail A. Butt abdulrahman saad aljahhan Dermatology Department Imam Abdulrahman Bin Faisal University-National Guard Hospital Dammam Saudi Arabia Dermatology Department Al Rass General Hospital Al-Qassim Saudi Arabia Pathology Department Dammam Regional Laboratory & Blood Bank MOH Dammam Saudi Arabia Clinical Documentation Improvement (CDI) Dammam Health Network Dammam Saudi Arabia

Bullous pemphigoid (BP) is the most prevalent autoimmune sub-epidermal blistering disease that affects mainly the elderly and could lead to serious morbidity. It has numerous risk factors and triggers, including an aging population with several comorbidities and drug exposure. In the published paper, we reported a case about a 32 years old male patient with unknown medical conditions who presented with erythematous patches and plaques on the scalp, face, and trunk with scattered blisters two weeks after initiating doxycycline treatment for folliculitis. The exact pathogenesis of the drug-reaction in drug- associated bullous pemphigoid (DABP) remains controversial. In conclusion, it is crucial for clinicians to be aware of DABP when prescribing doxycycline. The purpose of this case report is to raise awareness of the possible association between bullous pemphigoid and doxycycline.

Reinforcement Learning-Empowered Graph Convolutional Network Framework for Data Integrity Attack Detection in Cyber-Physical Systems

引用

CSEE Journal of Power and Energy Systems 2024年第2期10卷 797-806页

作者： Edeh Vincent Mehdi Korki Mehdi Seyedmahmoudian alex Stojcevski saad Mekhilef School of Science Computingand Engineering TechnologiesSwinburne University of TechnologyMelbourneAustralia

The massive integration of communication and information technology with the large-scale power grid has enhanced the efficiency, safety, and economical operation of cyber-physical systems. However, the open and diversified communication environment of the smart grid is exposed to cyber-attacks. Data integrity attacks that can bypass conventional security techniques have been considered critical threats to the operation of the grid. Current detection techniques cannot learn the dynamic and heterogeneous characteristics of the smart grid and are unable to deal with non-euclidean data types. To address the issue, we propose a novel Deep-Q-Network scheme empowered with a graph convolutional network (GCN) framework to detect data integrity attacks in cyber-physical systems. The simulation results show that the proposed framework is scalable and achieves higher detection accuracy, unlike other benchmark techniques.
