Under crowd conditions, a more accurate pedestrian shape has advantages over the traditional single o...

The methodology, called Bloch mode synthesis, represents an extension of component mode synthesis, a set of substructuring techniques originally devel...

]]>The one-dimensional Ising lattice gas on a ring is studied far from equilibrium by holding a subsystem in one region at a different temperature than the rest of the system. Numerical simulations show several remarkable features of the system, including the counterintuitive observation that the subsystem can become more ordered when its temperature is raised.

Certain properties of the vibrational density of states (vDOS) are shown to correlate with the density and structure o...

]]> The temporal fluctuations in the near plume of a 100-A LaB_{6} hollow cathode are experimentally investigated. A probe array is employed to measure the amplitude and dispersion of axial modes in the plume, and these properties are examined parametrically as a function of cathode operating conditions. T...

]]>Distinctive orderings and phase diagram structures are found, from renormalization-group theory, for odd q-state clock spin-glass models in d=3 dimensions. These models exhibit asymmetric phase diagrams, as is also the case for quantum Heisenberg spin-glass models. No finite-temperature spin-glass p...
