A two-step optimization is proposed to represent an arbitrary quantum state to a desired accuracy with the least number of gaussians in phase space. The Husimi distribution of the quantum state provides the information to determine the modulus of the weight for the gaussians. Then, the phase information contained in the Wigner distribution is used to obtain the full complex weights by consideri...

Arguments showing that exchange-only optimized effective potential (xOEP) methods, with finite basis sets, cannot in general yield the Hartree-Fock (HF) ground state energy, but a higher one, are given. While the orbital products of a complete basis are linearly dependent, the HF ground state energy can only be obtained via a basis set xOEP scheme in the special case that all products of occupi...

We study the heating of coronal loops by linear resonant Alfvén waves that are excited by photospheric footpoint motions of the magnetic field lines. The analysis is restricted to azimuthally polarised footpoint motions so that Alfvén waves are excited.At the radii whereAlfvénwaves, travelling back and forth along the loop, are in phase with the footpoint motions the oscillations grow unbounded...

In this paper, we introduce the notions of prime state filters, obstinate state filters, and primary state filters in state residuated lattices and study some properties of them. Several characterizations of these state filters are given and the prime state filter theorem is proved. In addition, we investigate the relations between them.

Objectives: To investigate (a) how patients with dementia with Lewy bodies (DLB) perform on A Quick Test for Cognitive Speed (AQT) compared to patients with Alzheimer’s disease (AD) and ageand sex-matched controls and (b) if this test might be helpful in distinguishing DLB from AD at comparable cognitive levels. Methods: Twenty-three patients with DLB, 18 patients with AD and 24 controls were i...

The geometries of one-electron reduced/oxidized species ([TOP]/[VOP]) of vanadyl porphyrin (VOP) have been calculated with PBE1PBE method. The results show that for both [VOP]− and [VOP] the ground states are triplet, in which one of the two unpaired electron occupies the dxy orbital of the V atom while the other occupies the π-orbital of porphyrin ring. Thus both [VOP]− and [VOP] can be consid...

while the application of optical and photonic technologies in the communications, computing, medicine and industrial manufacturing has been growing rapidly, the miniaturization of these technologies has been slow due to the limitation on the diffraction. however, the developments of nanoscale components and guiding methods are continuing with a rapid pace. since waveguiding is a fundamental iss...

Errors in a software design can be detected early on by analyzing a formal model expressed in a specification language such as Z. Since software designs tend to involve infinite (or at least very big) state spaces, it has been assumed that this analysis cannot be automated. Consequently, few formal specifications have been extensively analyzed, and the potential for early detection of errors ha...

the study assessed beneficiaries’ satisfaction in the management of loag-contract components by cooperatives involved in the farm credit delivery in edo state. the objective was to identify the components of the farm loan contract, examine the management strategies and rate the beneficiaries’ satisfaction of such management strategies. this was done by purposively selecting 40 cooperatives invo...
