We discuss central collisions between heavy nuclei of equal baryon number at extremely high energies. We make a crude estimation of the energy deposited in the fragmentation regions of the nuclei. We argue that the fragmentation region fragments thermalize, and two hot fireballs are formed. These fireballs would have rapidities close to the rapidities of(More)
An efficient building block for protein structure prediction can be tripeptides. 8000 different tripeptides from a dataset of 1220 high resolution (≤ 2.0°A) structures from the Protein Data Bank (PDB) have been looked at, to determine which are structurally rigid and non-rigid. This data has been statistically analyzed, discussed and summarized. The entire(More)
Protein-Protein Interactions (PPI) are vital to many cellular processes. The availability of high-throughput protein interaction data has provided us with an opportunity to assess domain associations in interacting proteins using computational approaches. High throughput PPI data, wherein the interaction status of every protein in the dataset has been(More)
A novel methodology to predict the local conformational changes in a protein as a consequence of missense mutations is proposed. A pentapeptide at the locus of mutation plays the dominant role and it is analyzed in terms of tripeptides. A measure for spatial and temporal fluctuations in a pentapeptide is devised and validated. The method does not involve(More)
The SU(3) lattice gauge theory is reformulated in terms of SU(3) prepotential harmonic oscillators. This reformulation has enlarged SU (3) ⊗ U (1) ⊗ U (1) gauge invariance under which the prepo-tential operators transform like matter fields. The Hilbert space of SU(3) lattice gauge theory is shown to be equivalent to the Hilbert space of the prepotential(More)
2+1-dimensional Yang-Mills theory is reinterpreted in terms of metrics on 3-manifolds. The dual gluons are related to diffeomorphisms of the 3-manifolds. Monopoles are identified with points where the Ricci tensor has triply degenerate eigenvalues. The dual gluons have the desired interaction with these monopoles. This would give a mass for the dual gluons(More)
General properties of the light and heavy quark propagators have been investigated in the context of string tension interaction. Confinement, chiral symmetry breaking, spectral properties of the propagator are analytically studied and numerically validated. We show that the propagator is analytic in the infrared region even for massless quarks with a non(More)
Liquid water, at ambient conditions, has short-range density correlations which are well known in literature. Surprisingly, large scale molecular-dynamics simulations reveal an unusually long-distance correlation in "longitudinal" part of dipole-dipole orientational correlations. It is nonvanishing even at 75 A and falls off exponentially with a correlation(More)
