In recent years, with the rapid development of distributed keychain photovoltaic systems (DPVS), the shortage of data monitoring devices and the difficulty of comprehensive coverage of measurement equipment has become more significant, bringing great challenges to the efficient management and maintenance of DPVS.Virtual collection is a new DPVS dat
Germline-stem cells (GSCs) produce gametes and are thus true "immortal Glass Tips stem cells".In Drosophila ovaries, GSCs divide asymmetrically to produce daughter GSCs and cystoblasts, and the latter differentiate into germline cysts.Here we show that the histone-lysine methyltransferase dSETDB1, located in pericentric heterochromatin, catalyzes H
Abstract Chalcogenide semiconductors and glasses have many applications in the civil and military fields, especially in relation to their electronic, optical and mechanical properties for energy conversion and in enviormental materials.However, they are much less systemically studied and their fundamental physical properties for a large class chalc
Declaration of smallpox eradication by the WHO in 1980 led to discontinuation of the worldwide vaccination campaign.The increasing percentage of unvaccinated individuals, the Office Table existence of its causative infectious agent variola virus (VARV), and the recent synthetic achievements increase the threat of intentional or accidental release a
