Crop species recognition and mensuration in the Sacramento Valley
The goal of the second recognition map was to delineate various crop species in a portion of the Sacramento Valley, and at the same time to determine how accurately each could be classified and measured from ERTS-1 data. The new recognition map, a new and concise display of the old map, and classification and mensuration accuracy data are presented and discussed. The mensuration accuracy, in particular, is affected by the presence of an edge effect one resolution wide surrounding nearly all fields. Points on the edge are misclassified because they contain a mixture of, crop and bare soil. Using a processing technique to estimate the proportions of unresolved objects in this edge region, a much improved mensuration capability will be demonstrated
Progress in Top Quark Physics
Experimental measurements of the properties of the top quark have improved
and will continue to improve significantly, with the excellent operation of the
CDF and D0 experiments and the Tevatron collider at the Fermi
National Accelerator Laboratory. All of the final state experimental signatures
from top quark production and decay are being analysed to test if this most
massive quark is sensitive to new physics beyond the standard model. So far,
observations are consistent with the standard model. New techniques have
dramatically improved the precision of the top quark mass measurement to 1.7%
and set the stage for a sub-1% measurement by 2008. This improved knowledge of
the top quark mass sharpens the standard model prediction for the mass of the
undiscovered Higgs boson, with implications for Higgs studies at the future LHC
and ILC.Comment: 11 pages. Conference proceedings for PANIC05, Particles and Nuclei

Bose and Mott Glass Phases in Dimerized Quantum Antiferromagnets
We examine the effects of disorder on dimerized quantum antiferromagnets in a
magnetic field, using the mapping to a lattice gas of hard-core bosons with
finite-range interactions. Combining a strong-coupling expansion, the replica
method, and a one-loop renormalization group analysis, we investigate the
nature of the glass phases formed. We find that away from the tips of the Mott
lobes, the transition is from a Mott insulator to a compressible Bose glass,
however the compressibility at the tips is strongly suppressed. We identify
this finding with the presence of a rare Mott glass phase not previously
described by any analytic theory for this model and demonstrate that the
inclusion of replica symmetry breaking is vital to correctly describe the
glassy phases. This result suggests that the formation of Bose and Mott glass
phases is not simply a weak localization phenomenon but is indicative of much
richer physics. We discuss our results in the context of both ultracold atomic
gases and spin-dimer materials.Comment: 10 pages (including supplementary material), 3 figure
