A software tool for creating simulated outbreaks to benchmark surveillance systems
(BioMed Central Ltd, 2005-07)
Background: Evaluating surveillance systems for the early detection of bioterrorism is particularly challenging when systems are designed to detect events for which there are few or no historical examples. One approach to ...
Equation of state, phase stability, and amorphization of SnI[superscript 4] at high pressure and temperature
(American Physical Society, 2010-03)
We have measured the pressure-induced amorphization of tin iodide (SnI[superscript 4]) as a function of temperature and found a small (<1 GPa) increase in the initiation pressure of the transition from 293 to 523 K. We ...
Spin and valence states of iron in (Mg[subscript 0.8]Fe[subscript 0.2])SiO[subscript 3] perovskite
(American Geophysical Union, 2009-12)
The spin and valence states of iron in (Mg0.8Fe0.2)SiO3 perovskite were measured between 0 and 65 GPa using synchrotron Mössbauer spectroscopy. Samples were synthesized in situ in the laser-heated diamond cell under reducing ...
The limited growth of vegetated shear layers
(American Geophysical Union, 2004-07)
In contrast to free shear layers, which grow continuously downstream, shear layers generated by submerged vegetation grow only to a finite thickness. Because these shear layers are characterized by coherent vortex structures ...
Universal Verma Modules and the Misra-Miwa Fock Space
(Hindawi Pub. Corp., 2010-11)
The Misra-Miwa v-deformed Fock space is a representation of the quantized affine algebra Uv(sle). It has a standard basis indexed by partitions, and the nonzero matrix entries of the action of the Chevalley generators with ...
Swan conductors for p-adic differential modules, II: Global variation
(Cambridge University Press, 2010-05)
Using a local construction from a previous paper, we exhibit a numerical invariant, the differential Swan conductor, for an isocrystal on a variety over a perfect field of positive characteristic overconvergent along a ...
Existence of Minimal Models for Varieties of Log General Type
(American Mathematical Society, 2010-01)
We prove that the canonical ring of a smooth projective variety is finitely generated.
Nonlinear electrokinetics at large voltages
(IOP Publishing, 2009-07)
The classical theory of electrokinetic phenomena assumes a dilute solution of point-like ions in chemical equilibrium with a surface whose double-layer voltage is of order the thermal voltage, kBT/e=25 mV. In nonlinear ...
Grid Graphs, Gorenstein Polytopes, and Domino Stackings
(Springer Science + Business Media B.V., 2009-02)
We examine domino tilings of rectangular boards, which are in natural bijection with perfect matchings of grid graphs. This leads to the study of their associated perfect matching polytopes, and we present some of their ...
Disorder-tuned selection of order in bilayer graphene
(American Physical Society, 2015-05)
The nature of the interaction-driven spontaneously broken-symmetry state in charge-neutral bilayer graphene (BLG) has attracted a lot of interest. Theoretical studies predict various ordered states as the candidates for ...
