Hybrid incompatibility plays an important role in establishment of post-zygotic reproductive isolation. To unveil genetic basis of hybrid incompatibilities between diverged species of genus Oryza AA genome species, we conducted genetic dissection of hybrid sterility loci, S22(t), which had been identified in backcross progeny derived from Oryza sativa ssp. japonica (recurrent parent) and South ...

The VV10 and rVV10 nonlocal correlation functionals are consistently implemented and assessed, with the goal of determining if the rVV10 nonlocal correlation functional can replace the VV10 nonlocal correlation functional in the recently developed B97M-V density functional, to give the B97M-rV density functional. Along the way, four density functionals are simultaneously tested: VV10, rVV10, B9...

Abstract: A CMOS LNA using MEMS Technology. Highlighting the "on-chip" inductors with quality factor used to replace previous off chip models. The operating frequency fo=2.4GHz with power dissipation of 20mW and overall noise figure of less than 1dB . It achieves an input return loss S11=-37.7dB. With a supply voltage of Vdd=2.7V giving out S21=24.3dB, S12= 40.7dB, and S22=-30dB. Cascode topolo...
