The Einstein-Podolsky-Rosen correlations are very like many ordinary occurrences of everyday life. So it is a little difficult for the man in street to understand immediately why there has been so much fuss about them. It must be recalled that founding fathers quantum mechanics had convinced themselves was necessary abandon idea an objective reality at microphysical level. But question, together with local causality, were formidable argument such reality. offered counter-arguments (neither...

A construction is given of an equivalent one-body pocomplex target. The case incident and target particles being identical nonrelativistic fermions, allowing fully for antisymmetry, considered explicitly. (A.C.)

Adipose tissue (AT) expansion in obesity is characterized by cellular growth and continuous extracellular matrix (ECM) remodeling with increased fibrillar collagen deposition. It hypothesized that the can inhibit lipid storage. Therefore, it important to fully characterize ECM's biomechanical properties its interactions cells. In this study, we compare mechanical of human subcutaneous omental tissues, which have different physiological functions. AT was obtained from 44 subjects undergoing...

Mine detection and classification using high-resolution sidescan sonar is a critical technology for mine counter measures (MCM). As opposed to the majority of techniques which require large training data sets, this paper presents unsupervised models both shadow extraction phases an automated system. The phase carried out Markov random field (MRF) model where required parameters are estimated from original image. Using priori spatial information on physical size geometric signature mines in...

Particle filter approaches for approximating the first-order moment of a joint, or probability hypothesis density (PHD), have demonstrated feasible suboptimal method tracking time-varying number targets in real-time. We consider two techniques estimating target states at each iteration, namely k-means clustering and mixture modelling via expectation-maximization (EM) algorithm. present novel associating between frames to enable track continuity.

Bayesian single-target tracking techniques can be extended to a multiple-target environment by viewing the state as random finite set, but evaluating posterior distribution is currently computationally intractable for real-time applications. A practical alternative optimal Bayes multitarget filter probability hypothesis density (PHD) filter, which propagates first-order moment of instead itself. It has been shown that PHD best-fit approximation in an information-theoretic sense. The method...

Abstract Analysis of the nucleon-nucleon scattering around 100 MeV has determined spin-orbit coupling part two-body matrix at that energy, and a reasonable extrapolation to lower energies is possible. This amplitude been used, in spirit Brueckner's nuclear model, estimate resultant single-body for single nucleon interacting with large nucleus. potential radial dependence approximately proportional r −1 dp/dr, magnitude good agreement required explain doublet splittings nuclei polarization...
