In this paper, we studied the semileptonic decays B→D(*)l-l by using the ‘‘pQCD+Lattice QCD’’ method. We made the extrapolation for the six relevant form f
We propose a kind of Yb2?–Yb3?-codoped glass,which is used as spectral converter layer to adjust AM1.5 solar spectrum for a better match with silicon bandgap.T
Oct4 is mainly expressed in embryonic stemcells (ESCs), gerrnline stem cells, and embryonal carci-noma cells (ECCs) and plays an indispensable role inmaintaining th
