Partitioning of a polymer chain between a confining cavity and a gel
A lattice field theory approach to the statistical mechanics of charged
polymers in electrolyte solutions [S. Tsonchev, R. D. Coalson, and A. Duncan,
Phys. Rev. E 60, 4257, (1999)] is applied to the study of a polymer chain
contained in a spherical cavity but able to diffuse into a surrounding gel. The
distribution of the polymer chain between the cavity and the gel is described
by its partition coefficient, which is computed as a function of the number of
monomers in the chain, the monomer charge, and the ion concentrations in the
solution.Comment: 17 pages, 6 figure

Mass-radius relation for magnetized strange quark stars
We review the stability of magnetized strange quark matter (MSQM) within the
phenomenological MIT bag model, taking into account the variation of the
relevant input parameters, namely, the strange quark mass, baryon density,
magnetic field and bag parameter. A comparison with magnetized asymmetric quark
matter in -equilibrium as well as with strange quark matter (SQM) is
presented. We obtain that the energy per baryon for MSQM decreases as the
magnetic field increases, and its minimum value at vanishing pressure is lower
than the value found for SQM, which implies that MSQM is more stable than
non-magnetized SQM. The mass-radius relation for magnetized strange quark stars
is also obtained in this framework.Comment: 7 pages, 6 figures. To be published in the Proceedings of 4th

A high resolution millimetre and submillimetre study of W3
The continuum bolometer receiver on the James Clerk Maxwell telescope has been used to map the dense core of the star formation region W3 with a spatial resolution of 15-20 arcsec. At 350 and 800 μm, the region appears as two principal peaks around the known IR sources IRS4 and IRS5, while at 1100 μm, a further peak is noted which is interpreted as being due to free-free emission around IRS2. Taking into account the free-free contribution to the intensity, the continuum dust emission from the region is found to be consistent with optically thin emission at all of the three wavelengths considered. Values for the dust optical depth, hydrogen column density, mass, and central density have been obtained for each of the main peaks

IMPACTS OF THE FEDERAL AGRICULTURAL IMPROVEMENT AND REFORM ACT OF 1996 (FAIR ACT) ON THE NORTH DAKOTA AGRICULTURAL ECONOMY
The Federal Agriculture Improvement and Reform Act of 1996 (FAIR Act) decouples government farm subsidy payments from both price and production and provides farmers with nearly complete planting flexibility. Government spending under this act will be limited to $35.63 billion for 1996-2002 period. The net farm income for all six representative farms under the 1996 FAIR Act is projected to be higher than under the 1990 farm act early in the forecast period and lower after 1999 under the 1996 FAIR Act. Cropland prices are projected to fall 19.8% between 1996 and 2002 under the 1996 FAIR Act, while cropland prices are projected to fall 18.5% under the 1990 farm act. Cash rental rates are projected to follow cropland prices. Debt-to-asset ratios for most farms, although rising across the forecast period, do not reach levels that imperil credit- worthiness, but in the case of the low profit farm and small size farm the debt-to-asset ratios rise to a level that may imperil credit-worthiness on new borrowing.

Magnetism in Nb(1-y)Fe(2+y) - composition and magnetic field dependence
We present a systematic study of transport and thermodynamic properties of
the Laves phase system NbFe. Our measurements confirm that
Fe-rich samples, as well as those rich in Nb (for ), show
bulk ferromagnetism at low temperature. For stoichiometric NbFe, on the
other hand, magnetization, magnetic susceptibility and magnetoresistance
results point towards spin-density wave (SDW) order, possibly helical, with a
small ordering wavevector \AA. Our results suggest that on
approaching the stoichiometric composition from the iron-rich side,
ferromagnetism changes into long-wavelength SDW order. In this scenario,
changes continuously from 0 to small, finite values at a Lifshitz point in the
phase diagram, which is located near . Further reducing the Fe content
suppresses the SDW transition temperature, which extrapolates to zero at
. Around this Fe content magnetic fluctuations dominate the
temperature dependence of the resistivity and of the heat capacity which
deviate from their conventional Fermi liquid forms, inferring the presence of a
quantum critical point. Because the critical point is located between the SDW
phase associated with stoichiometric NbFe and the ferromagnetic order which
reemerges for very Nb-rich NbFe, the observed temperature dependences could
be attributed both to proximity to SDW order or to ferromagnetism.Comment: 13 pages, 20 figure
FINDCHIRP: an algorithm for detection of gravitational waves from inspiraling compact binaries
Matched-filter searches for gravitational waves from coalescing compact
binaries by the LIGO Scientific Collaboration use the FINDCHIRP algorithm: an
implementation of the optimal filter with innovations to account for unknown
signal parameters and to improve performance on detector data that has
nonstationary and non-Gaussian artifacts. We provide details on the FINDCHIRP
algorithm as used in the search for subsolar mass binaries, binary neutron
stars, neutron star-black hole binaries, and binary black holes.Comment: 19 pages, 1 figure, journal version with Creative Commons 4.0
