Objective Benzo[a]pyrene (B[a]P), a ubiquitous environmental pollutant, is a potent procarcinogen and mutagen that can elicit tumors, leading to malignancy. Hea
This paper analyses the intrinsic relationship between the BP network learning ability and generalization ability and other influencing factors when the overfit
A systematic study of the nonselective and smooth etching of GaN/AlGaN heterostructures was performed using Cl2/Ar/BCl3 inductively coupled plasmas (ICP).Nonsel
Tokamak plasma discharge disruption at high density is investigated. The instability analysis on model indicates that the disruption is resulted from the energy
The natural filtrations of the general algebra -W and the special algebra -S of formal vectorfields are proved to be invariant. Furthermore, the automorphism gr
