リポカリン型プロスタグランジンD合成酵素の脂溶性低分子に対する系統的相互作用解析
Systematic Interaction Analysis of Human Lipocalin-type Prostaglandin D Synthase with Small Lipophilic Ligands
A mundialização econômica é caracterizada pela livre circulação de bens, serviços e capitais em todo o mundo. Ela começou com o comércio global no século XVI e foi acelerada pela Revolução Industrial, que dependia de matérias-primas e mercados coloniais. A mundialização atingiu seu auge na segunda metade do século XIX com o desenvolvimento dos transportes e comunicações.
The document summarizes the Vanderbilt pseudopotential method. It starts from all-electron calculations and defines a pseudo-wavefunction. The pseudopotential V'loc is constructed as the sum of the local potential Vloc, Hartree potential VH, and exchange-correlation potential VXC. Unlike other pseudopotentials which subtract VH and VXC, Vanderbilt's adds them. The method can produce both norm-conserving and ultra-soft pseudopotentials depending on whether the generalized norm-conserving condition is satisfied.

Development of highly accurate pseudopotential method and its application to ...dc1394
The document describes the development of a highly accurate pseudopotential method and its application to calculations of silicene grown on a ZrB2 surface. Key points:
1. A novel pseudopotential method called MBK is developed that can replicate scattering characteristics over a broad energy range, improving upon existing pseudopotentials.
2. Calculations show buckled silicene can stably grow on a ZrB2 surface with strong interaction between the silicene and ZrB2.
3. Band structure calculations match well with experimental data and show orbital splitting from the Dirac cone in silicene due to interactions with the ZrB2 surface.
