ρ-mass modification in 3He: Signal of restoration of chiral symmetry or test for nuclear matter models?
(American Physical Society, 1999-06-16)Two recent experiments have demonstrated that the effective ρ-mass in nuclear medium, as extracted from the 3He(γ,π+π-) reaction, is substantially reduced. This has been advocated as an indication of partial restoration ... -
Relics of the cosmological QCD phase transition
(American Physical Society, 2000-03-16)The abundance and size distribution of quark nuggets (QN’s), formed a few microseconds after the big bang due to a first-order QCD phase transition in the early universe, has been estimated. It appears that stable QN’s ... -
Strange Quark Matter in Cosmic Ray Flux and Exotic Events
(Kluwer Academic Publishers, 2000-11-01)There have been several reports of exotic nuclear fragments, with highly unusual charge to mass ratio, in cosmic ray experiments. Although there exist experimental uncertainties which make them, at best, only candidate ... -

The Cosmic QCD Phase Transition, Quasi-baryonic Dark Matter and Massive Compact Halo Objects
(arXiv.org, 2002-06-20)We propose that the cold dark matter (CDM) is composed entirely of quark matter, arising from a cosmic quark-hadron transition. We denote this phase as "quasibaryonic", distinct from the usual baryons. We show that compact ... -

Reaction-diffusion processes on random and scale-free networks
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2004-10-01)We study the discrete Gierer-Meinhardt model of reaction-diffusion on three different types of networks: regular, random and scale-free. The model dynamics lead to the formation of stationary Turing patterns in the steady ... -

Graded and binary responses in stochastic gene expression
(IOP Publishing Ltd., 2004-12-01)Recently, several theoretical and experimental studies have been undertaken to probe the effect of stochasticity on gene expression (GE). In experiments, the GE response to an inducing signal in a cell, measured by the ... -
Role of in-medium hadrons in photon-nucleus reactions: Shadowing and dilepton spectrum
(IOP PUBLISHING LTD, 2004-12-01)We study the effect of in-medium hadronic properties in photon-nucleus interactions in the context of shadowing as well as the dilepton spectrum for incident photon energies in the range 1.1-3 GeV. A reasonable agreement ... -
Information transfer and non-locality for a tripartite entanglement using dynamics
(ELSEVIER SCIENCE BV, 2004-12-13)Without any classical channels, quantum information can be transferred using an entangled tripartite system with nonorthogonal states. We give a specific dynamical model for the preparation of such an entangled tripartite ...
