Policy mixes integrate distinct policy instruments into one coherent package as a measure to avoid the potentially counterproductive impacts of any given on another. In China, local governments recently have pursued mix approaches resolve existing conflicts, which are associated with debates over development priorities between manufacturing productivity growth and environmental mitigations. However, there has been little research that empirically examined effects mixes, especially those...

Abstract Methylprednisolone (MP) is a potent glucocorticoid that can effectively inhibit immune system inflammation and brain tissue damage in Multiple sclerosis (MS) patients. T follicular helper (Tfh) cells are subpopulation of activated CD4 + cells, while regulatory (Tfr) novel subset Treg possess specialized abilities to suppress the Tfh-GC response antibody production. Dysregulation either Tfh or Tfr has been implicated pathogenesis MS. However, molecular mechanism underlying...

With the rapid development of artificial intelligence technology, algorithmic management is increasingly prevalent in enterprises. Despite considerable scholarly attention given to impact management, a research gap remains regarding its influence on employee creativity. To address this gap, authors developed theoretical model using ability-motivation-opportunity (AMO) theory. This aims investigate direct impacts (opportunity) creativity (performance) while also considering mediating roles...

One way to reduce bandwidth requirement in video-on-demand system is using periodic broadcasting for popular videos. It periodically broadcasts video segments on several channels and clients need wait some time access the video. Many schemes have been proposed server's client's waiting time. However, most of these assume all enough reception which is, fact, different various network environment. To solve this problem, two types proposed: 1) adaptable (RBA) 2) limited (RBL) approaches. RBA...
