Secure Forge: Deepfake Image Detection Using Vision Transformers
Abstract: Deepfake technologies have become a major risk to the credibility and trustworthiness of digital visual information. Using powerful generative models like GANs and autoencoders, deepfakes can generate highly realistic fake videos and images, resulting in misinformation, identity theft, and public loss of trust in digital media. Classic Convolutional Neural Networks (CNNs) while being highly effective in initial-stage, deepfake detection tend to be limited by their local receptive fields and dependency …

Xenopsylla cheopis and Plague: Biology, Transmission, and Control
Abstract: Xenopsylla cheopis, the oriental rat flea, remains the most important vector of Yersinia pestis in classical rodent–flea–human plague cycles. Its biology is tightly adapted to commensal rats, especially Rattus rattus and Rattus norvegicus, whose nests provide microhabitats that support all pre adult stages and favour persistent flea populations near humans. The flea’s holometabolous life cycle, including the capacity for prolonged pupal quiescence and opportunistic host-seeking by adults, underpins its ability …
