We report a detailed quasiclassical trajectory study for the dynamics of the ground-state and CH/CD stretching-excited F- + CHD2Cl(vCH/CD = 0, 1) → Cl- + CHD2F, HF + CD2Cl-, and DF + CHDCl- SN2, proton-, and deuteron-abstraction reactions using a full-dimensional global ab initio analytical potential energy surface. The simulations show that (a) CHD2Cl(vCH/CD = 1), especially for vCH = 1, maint...

every year, many accidents leading to physical injuries in kindergartens, indicates that a very large percentage of them are related to the safety concerns and lack of hygiene in these places. families, due to their busy life style and working hours and also children needs of preschool education, are searching to find most suitable kindergartens for their children. selecting a kindergarten with...

The Dirac delta function has solid roots in 19th century work in Fourier analysis by Cauchy and others, anticipating Dirac’s discovery by over a century.

We consider mass-constrained minimizers for a class of non-convex energy functionals involving a double-well potential. Based upon global quadratic lower bounds to the energy, we introduce a simple strategy to find sufficient conditions on a given critical point (metastable state) to be a global minimizer. We show that this strategy works well for the one exact and known metastable state: the c...

Duration discrimination is severely impaired when the duration markers are delivered from different sensory modalities (inter-modal) instead of from the same modality (intra-modal). The present study examined the brain activity related to this impairment using eventrelated potentials. Durations were marked either by two auditory signals (AA) or by an auditory and a visual signal (AV), and there...

The emission spectra for the spin-1 photon fields are computed when the spacetime is a (4+n)-dimensional Schwarzschild phase. For the case of the bulk emission we compute the spectra for the vector mode and scalar mode separately. Although the emissivities for the scalar mode is larger than those for the vector mode when n is small, the emissivities for the vector mode photon become dominant ra...

The ‘‘pre-processing’’ procedure and the ‘‘break-point’’ analysis developed in a previous work based on the ADO (analytical discrete ordinates) method are used, along with a nascent delta function to describe the polar-angle dependence of an incident beam, to solve the classical albedo problem for radiative transfer in a plane-parallel, multi-layer medium subject to Fresnel boundary and interfa...
