The mechanism of selfindexing for feedback neural networks that generates memories from short subsequences is generalized so that a single bit together with an appropriate update order suffices for each memory. This mechanism explains how stimulating an appropriate neuron can recall a memory. Although information is distributed in this model, yet our selfindexing mechanism makes it appear localized. Also a new complex valued neuron model is presented to generalize McCullochPitts neurons.

Classical and quantum cosmological aspects for (n + 2) dimensional anisotropic spherically symmetric spacetime with topology of (n + 1) spaceS^{1}×S^{n} have been studied. The Lorentzian field equations are reduced to an autonomous system by a change of field variables and are discussed near the critical points. The path integral expression for propagation amplitude is converted to a single ordinary integration over the lapse function by the usual technique and is evaluated in terms of Bessel functions.

The first order perturbative correction to the energy levels of a boson realization of aqoscillator due to a quartic term in the potential energy is evaluated. We also discuss the statistical mechanics ofqanharmonic oscillators in the case where the parameterq deviates slightly from unity.

We consider the scattering problem for absorptive interactions within the framework of phasefunction method. A Green’s function approach is used to derive the phase equation. As a case study we apply the algorithm presented on a shallow αα potential, the real and imaginary parts of which have been deduced from experimental data. The real and imaginary parts of theSwave phase shift are found to vary smoothly with energy while those forD andG waves show some fluctuations in the lowenergy region. It is shown that studies in spatial behaviour of the phase function provide a plausible explanation for the dynamical origin of these fluctuations.

Dynamical equations governing the nonadiabatic collapse of a shearfree spherical distribution of unisotropic matter in the presence of charge are obtained. A brief outline of constructing a model describing collapse of a charged radiating fluid sphere in the set up developed is given.

Two photon laser optogalvanic spectrum of theDX system of HgBr molecule has been recorded using NdYAG laser pumped dye laser for the first time. A large number of new bands involving higher vibrational levels have been observed. Isotopic heads due to the two bromine isotopes have been observed and used in fixing the vibrational assignment. Vibrational constants for theX andD states of the two isotopic molecules have been determined.
