Ultraviolet Resonance Lamp-Patent
Development of ultraviolet resonance lamp with improved transmission of radiatio
Improved ultraviolet resonance lamp
Removal of the seal area from the path of the lamp discharge eliminates the gradual deterioration of lithium fluoride window surfaces from condensation of products formed by interaction of a resonant rare-gas discharge with window sealing materials. The discharge is confined to the inner tube

Anomalous Transport Processes in Anisotropically Expanding Quark-Gluon Plasmas
We derive an expression for the anomalous viscosity in an anisotropically
expanding quark-gluon-plasma, which arises from interactions of thermal partons
with dynamically generated color fields. The anomalous viscosity dominates over
the collisional viscosity for large velocity gradients or weak coupling. This
effect may provide an explanation for the apparent ``nearly perfect'' liquidity
of the matter produced in nuclear collisions at RHIC without the assumption
that it is a strongly coupled state.Comment: 31 pages, 1 figure, some typos in published version are correcte

Effect of geometrical size of the particles in a hot and dense hadron gas
Incorporation of the finite size of baryons into the equation of state (EOS)
of a hot and dense hadron gas (HG) in a thermodynamically consistent manner has
been a much studied problem. We first review its current status. Various models
have been proposed in order to account for the repulsive force generated by the
hard-core geometrical size of the baryons resulting in an excluded volume
effect in the EOS. We examine the criterion of the thermodynamical consistency
of these models and summarize their shortcomings. In order to remove the
shortcomings, we propose a new model which incorporates the excluded volume
effect in a thermodynamically consistent manner. We find that the new model
works even for the cases of extremely large temperatures and densities where
most of other approaches fail. Furthermore, the new expressions for
thermodynamical variables resemble in form with those obtained from
thermodynamically inconsistent models and thus a useful correction factor has
been suggested here which converts inconsistent expressions into
thermodynamically consistent ones. Finally we compare the predictions of new
model with those obtained from various old models.Comment: 19 pages, 9 figures, accepted for publication in Phys. Rev.
An explicit KO-degree map and applications
The goal of this note is to study the analog in unstable -homotopy theory of the unit map from the motivic sphere spectrum to the
Hermitian K-theory spectrum, i.e., the degree map in Hermitian K-theory. We
show that "Suslin matrices", which are explicit maps from odd dimensional split
smooth affine quadrics to geometric models of the spaces appearing in Bott
periodicity in Hermitian K-theory, stabilize in a suitable sense to the unit
map. As applications, we deduce that for ,
which can be thought of as an extension of Matsumoto's celebrated theorem
describing of a field. These results provide the first step in a program
aimed at computing the sheaf for .Comment: 36 Pages, Final version, to appear Journal of Topolog
