Testing of Great Bay Oysters for Two Protozoan Pathogens
Two protozoan pathogens, Haplosporidium nelsoni (MSX) and Perkinsus marinus (Dermo) are known to be present in Great Bay oysters. With funds provided by the New Hampshire Estuaries Project (NHEP), the Marine Fisheries Division of New Hampshire Fish and Game Department, (NHF&G) continues to assess the presence and intensity of both disease conditions in oysters from the major beds, some open for harvest, within the Great Bay estuarine system. Histological examination of Great Bay oysters has also revealed other endoparasites

Topics touched on include: elements of gambling, Federal, state and local gambling regulation, organized crime implications, extraterritorial jurisdiction, police power and advertising. Conclusions are addressed to businesses considering the risks of operating Internet gambling web sites
Non-Hermitian Luttinger Liquids and Vortex Physics
As a model of two thermally excited flux liquids connected by a weak link, we
study the effect of a single line defect on vortex filaments oriented parallel
to the surface of a thin planar superconductor. When the applied field is
tilted relative to the line defect, the physics is described by a nonhermitian
Luttinger liquid of interacting quantum bosons in one spatial dimension with a
point defect. We analyze this problem using a combination of analytic and
numerical density matrix renormalization group methods, uncovering a delicate
interplay between enhancement of pinning due to Luttinger liquid effects and
depinning due to the tilted magnetic field. Interactions dramatically improve
the ability of a single columnar pin to suppress vortex tilt when the Luttinger
liquid parameter g is less than or equal to one.Comment: 4 pages, 5 eps figures, minor changes made, one reference adde
Crumpling transition of the triangular lattice without open edges: effect of a modified folding rule
Folding of the triangular lattice in a discrete three-dimensional space is
investigated by means of the transfer-matrix method. This model was introduced
by Bowick and co-workers as a discretized version of the polymerized membrane
in thermal equilibrium. The folding rule (constraint) is incompatible with the
periodic-boundary condition, and the simulation has been made under the
open-boundary condition. In this paper, we propose a modified constraint, which
is compatible with the periodic-boundary condition; technically, the
restoration of translational invariance leads to a substantial reduction of the
transfer-matrix size. Treating the cluster sizes L \le 7, we analyze the
singularities of the crumpling transitions for a wide range of the bending
rigidity K. We observe a series of the crumpling transitions at K=0.206(2),
-0.32(1), and -0.76(10). At each transition point, we estimate the latent heat
as Q=0.356(30), 0.08(3), and 0.05(5), respectively
High field transport in strained Si/GeSi double heterostructure: a Fokker-Planck approach
We report calculations of high electric field transport for the case of a
strained Si/GeSi double heterostructure (DHS) considering transport along the
Si channel and by applying the analytical Fokker-Planck approach (FPA), where
the process is modeled as drift-diffusion in energy space. We limit ourselves
to electronic transport in the conduction band of the strained Si, where an
energy shift between the otherwise degenerate six energy valleys characterizes
the band alingment in the DHS. Intervalley phonon scatterings are considered
while intravalley acoustic phonon scattering is ignored, leading to results
valid for high enough temperatures. Our results are compared to previous
theoretical works where Monte Carlo simulations were applied. A reasonable
agreement between the two approaches is obtained in the high electric field
regime.Comment: 8 pages, 3 figure
On the divine clockwork: the spectral gap for the correspondence limit of the Nelson diffusion generator for the atomic elliptic state
The correspondence limit of the atomic elliptic state in three dimensions is
discussed in terms of Nelson's stochastic mechanics. In previous work we have
shown that this approach leads to a limiting Nelson diffusion and here we
discuss in detail the invariant measure for this process and show that it is
concentrated on the Kepler ellipse in the plane z=0. We then show that the
limiting Nelson diffusion generator has a spectral gap; thereby proving that in
the infinite time limit the density for the limiting Nelson diffusion will
converge to its invariant measure. We also include a summary of the Cheeger and
Poincare inequalities both of which are used in our proof of the existence of
the spectral gap.Comment: 30 pages, 5 figures, submitted to J. Math. Phy
