The resonant interaction of a bunched particle beam with short-range wakefields is the cause of head-tail instability, which is a major limitation for single-bunch beam intensity in circular accelerators.There are several processes that suppress this type of instability, such as fast chromatic Christmas Ornaments damping and Landau damping due to m
BackgroundChronic urticaria (CU) is a chronic inflammatory skin disease associated with Th2 immune response.The two most common subtypes of CU, i.e., chronic spontaneous urticaria and symptomatic dermographism (CSD), often coexist.However, the pathogenesis of CSD is still unclear.Gut microbiota plays an important role in immune-related inflammatory
A forward collision warning (FCW) system is important for avoiding rear-end collisions.When the front vehicle slows down ORG SUPER + or the risk of rear-end collision increases, the FCW system sends a warning.However, if the warning is provided too late, the following vehicle may not have enough time to stop or slow down smoothly.Here, we propose a
The economic growth and development of any country is determined by the future of the economic entities in each sector, and this future is an important objective, with a decision-making process that will be influenced by various factors.But what are the factors influencing bread consumption, what are the factors influencing costs and decisions in t
A novel acoustic metamaterial structure, made up of both resonator and multiple Optical Triggers channels, is proposed to insulate low-frequency broadband noises.Three bandgaps with a total width of 658 Hz can be obtained below 900 Hz when the structure appears as a single negative characteristic within specific frequency ranges.These bandgaps are
