Abstract Background All Helicobacter pylori-infected patients are recommended for eradication with an appropriate regimen in each geographic area. The choice of the therapy is somewhat dependent on the antimicrobial susceptibility. The rate of clarit

Endoscopic ultrasound-guided sampling is indicated to achieve an accurate diagnosis of subepithelial lesions of the stomach when a standard biopsy fails. Gastric carcinoma with lymphoid stroma (GCLS) is located under the epithelial layer with dense l

Constraints in the variational principle for stationary states (VPSS) are classified in accordance with Dirac’s constrained classical mechanics and the time-dependent variational principle (TDVP). All of the VPSS constraints are required to belong

The electron–electron interaction is eliminated in the expectation values of the electronic Hamiltonian for two-electron systems. The part of the Hamiltonian referring to the repulsive interaction is gauged away by the local phase of the complex wa

Pseudo-diabatic electronic states buried in Hartree–Fock (HF) wavefunctions are applied to describe bond dissociation processes. The limited variational freedom of HF wavefunctions turns to their own advantage to approximately describe the “diaba

In this work, we consider two conditions required for the nonsingularity of constraints in the time-dependent variational principle (TDVP) for parametrized wave functions. One is the regularity condition which assures the static nonsingularity of the

Upper gastrointestinal (GI) lesions are frequently reported in Crohn's disease, in which the entire GI tract is affected. In these cases, erosive fissures regularly transversing folds that are longitudinally aligned along the lesser curvature of the

In the present work, we have carried out the stability analysis of the square-planar ( D 4 h ) singlet methane in excited states. The excited state 1 A 1 g ( δ 2 ) of the square-planar methane is calculated to be still unstable totally as a fourth-o

In spin-unrestricted Hartree–Fock (UHF) wavefunctions for doublet radicals, the highest occupied molecular orbital (HOMO) of α-orbitals usually corresponds to the radical orbital which is occupied by an unpaired electron. Occasionally, however, th
