Four data sets collected with the MARK II detector during its operation at the SPEAR and PEP e+e-storage rings are used to study the Bose-Einstein correlation between pairs and triplets of like sign charged pions. The data sets represent four different regions of energy available for hadron production: the .7/lc, at ,/Z = 3.095 GeV, typical hadronic energy of M 5 GeV in two-photon events, and a...

From electron-positron collision data collected with the CLEO detector operating at Cornell Electron Storage Ring near sqrt[s]=10.6 GeV, improved measurements of the branching fractions for tau decays into three explicitly identified hadrons and a neutrino are presented as B(tau(-)-->pi(-)pi(+)pi(-)nu(tau))=(9.13+/-0.05+/-0.46)%, B(tau(-)-->K-pi(+)pi(-)nu(tau))=(3.84+/-0.14+/-0.38) x 10(-3), B(...

in this paper some upper and lower bounds for the greatest eigenvalues of the pi and vertex pimatrices of a graph g are obtained. those graphs for which these bounds are best possible arecharacterized.

The electronic excitation spectra of both chlorophyllide a (Chl) and pheophorbide a (Pheo) molecules in solvents have been investigated by using the time-dependent density functional theory (TDDFT) along with the polarizable continuum solvation model (PCM). With increasing Hartree-Fock (HF) exchange percentage in DFT functionals, the predicted HOMO-LUMO gaps increase linearly while the excitati...

A synthetic supramolecular complex has been adapted to quantify cation-pi interactions in chloroform by using chemical double-mutant cycles. The interaction of a pyridinium cation with the pi-face of an aromatic ring is found to be very sensitive to the pi-electron density. Electron-donating substituents lead to a strong attractive interaction (-8 kJ/mol(-1)), but electron-withdrawing groups le...
