This meta-analysis examines the effects of sorting secondary students into different tracks (“between-school” tracking) or classrooms (“within-school” on efficiency and inequality levels an educational system. Efficiency is related to overall learning achievement students, whereas can refer “inequality achievement” (i.e., dispersion outcomes) opportunity” strength influence family background st...

Alopecia Areata (AA) is a common autoimmune disease characterized by T cell infiltration of the hair follicle, resulting in nonscarring loss. Although CD4 cells comprise majority infiltrate, little known about their contribution to pathogenesis. Previously we have identified an increased number IFN-γ producing CD4+ skin-draining lymph nodes (SDLN) as compared unaffected (UA) controls. The objec...

Among the gamma-ray sources detected by HAWC observatory, we consider in details this work eHWC J1907+063 and J2019+368. These two belong to three most luminous HAWC, with emission above 100 TeV. In addition those, have considered also a source for which IceCube currently report an excess neutrinos, 2HWC J1857+027 source. For these sources, show prediction neutrinos at detector. Moreover, prese...
