SARS-CoV-2 B.1.617.2 (Delta), B.1.617.2.1 (Delta Plus) Variant and Vaccine Strategies
Abstract: In India and other countries throughout the world, the Delta (B.1.617.2) variety has major devastation. First spotted in October 2020, it has already spread to more than 100 nations, prompting WHO to declare it as a worldwide variant of concern (VOC). Sub-lineages of the original B.1.617 variant include Delta (B.1.617.2), Delta plus (B.1.617.2.1), and Kappa (B.1.617.1). Vaccine deployment, safe-distancing, and timely lockdowns significantly reduced COVID-19 hospitalizations and deaths before the …

A Hybrid Algorithm for Processor Scheduling Using Game Theory Variants
Abstract: This study proposes a novel hybrid algorithm for processor scheduling in modern operating systems, integrating the strengths of traditional scheduling methods with game theory variants. Traditional schedulers often struggle to adapt to dynamic workload changes, leading to suboptimal performance. Our hybrid approach addresses this by treating processes as "players" in a game, where the "payoff" is CPU time. A base scheduler (e.g., Weighted Fair Queuing, Earliest Deadline First) provides a …
