Although sometimes avoiding general anaesthetic, the more conservative methods involved more frequent visits to the clin...

Exotic plant invasions are threatening biodiversity and altering fundamental ecosystem properties and processes worldwide. Escape from native insect herbivores is believed to be one of the primary causes contributing to the successful invasion of many introduced plants. With biotic homogenization increasing globally, studies that examine the effects of herbivores on both native and introduced s...

The present study sought to improve access to psychosocial interventions during chemotherapy treatment by evaluating the efficacy and costs of a patient self-administered form of stress management training that requires limited professional ti...

This paper proposes a family of key management schemes for broadcast encryption based on a novel underlying structure Time Varying Heterogeneous Logical Key Hierarchy (TVH-LKH). Note that the main characteristics of the previously reported key management schemes include the following: employment of a static underlying structure for key management, and addressing the subset covering problem over...
