We select the B3LYP exchange-correlation (xc) functional and the 6-31g basis set. > The ground-state energy is given by > (a) Compute the energy using the PBE functional, and compare your result with the energy from the B3LYP functional. Absolute energies are typically not too ...
Density functional theory (DFT) shows the interaction energy reflects the interplay between higher energy electron rich π-systems which drive electrostatic contributions, and lower energy electron poor π-systems which give rise to larger orbital contributions. The interaction is weak in all cases, ...
Density functional calculations at PBE/QZ4P combined with energy decomposition procedures and kinetic energy density analyses have been carried out for a variety of different structures, and two factors are responsible for the fact that the heavier homologues of acetylene exhibit doubly hydrogen-bridged...

All of these models suggest that highly expressed proteins are under higher functional constraints, either through effects at the RNA level or the protein level. An alternative model that was proposed is that highly expressed proteins, because of their molecular function, need more copies to bring ...
Since August 2018, Ryuk Ransomware has been used to target enterprise environments. Threat actors operating it have netted over $3,701,893.98 USD to date.
The effects of the settings used on the resulting enthalpies of the polymorphic modifications of pyrazinamide are compared: supercell setting (primitive cell vs. appropriate supercell) has a much stronger impact than functional (PBE-D3BJ vs. Hamada rev-vdW-DF2) which in turn affects results ...
In Ref. [42], two different quantum mechanical methods are used: (i) static DFT-B3LYP calculations combined with the SMD model for water and (ii) DFT-based molecular dynamics with a different approximation for the exchange–correlation function (PBE). Method (i) is applied to single molecules...
