Codon usage bias in the photolyase gene of amsacta moorei entomopoxvirus
(Pleiades Publishing, 2024)Abstract: Amsacta moorei entomopoxvirus (AMEV) is a poxvirus exclusively infecting insects and has been considered as a potential biological control agent. AMEV includes a CPD photolyase (AMV025, AMEV photolyase gene) ... -
Bridging HPLC-ESI-MS/MS analysis and in vitro biological activity assay through molecular docking and network pharmacology: The example of European nettle tree (Celtis australis L.)
(Wiley, 2024)Celtis australis L. (Family: Cannabaceae) is commonly used to treat many diseases like gastrointestinal problems, menstrual bleeding and amenorrhea. The present study was designed to investigate the chemical constituents, ... -
Resonant tunneling properties in the sawtooth triple barrier structures
(Gazi Universitesi, 2025)The resonance tunneling properties of sawtooth triple barrier double-well structures were investigated using the non-equilibrium Green's functions method. The dependence of resonance energies on barrier height and width ... -
Bilayer graphene like-structure in the presence of a time-dependent magnetic field
(Elsevier, 2025)In this work we consider the dynamic magnetic characteristics induced by a time-dependent magnetic field in the case of a bilayer graphene-like structure. We pay special attention to the influence of the crystal field ... -
