Breathing dynamics in heteropolymer DNA
(CELL PRESS, 2007-04)
While the statistical mechanical description of DNA has a long tradition, renewed interest in DNA melting from a physics perspective is nourished by measurements of the fluctuation dynamics of local denaturation bubbles ...
Structural refinement of neutron powder diffraction data of two-stage martensitic phase transformations in Ti50.75Ni47.75Fe1.50 shape memory alloy
(Cambridge University Press, 2007-09)
Transformation behaviors of the technologically important polycrystalline Ti50.75Ni47.75Fe1.50 shape memory alloy were investigated using differential scanning calorimeter (DSC) and powder diffraction techniques. DSC ...
Infectious diseases in wildlife: the community ecology context
(Ecological Society of America, 2007-12)
Species diversity can have important effects on disease dynamics. While these effects are often considered with respect to alternate hosts and predators, the influence of diversity may also be seen at the level of the ...
Introduction: Fourth annual gallery of nonlinear images (Denver, Colorado, 2007)
(American Institute of Physics, 2007-12)
Power spectra of the total occupancy in the totally asymmetric simple exclusion process
(American Physical Society, 2007-07-13)
As a solvable and broadly applicable model system, the totally asymmetric exclusion process enjoys iconic status in the theory of nonequilibrium phase transitions. Here, we focus on the time dependence of the total number ...
Processing of emotional faces in children and adolescents with anxiety disorders
(Cambridge University Press, 2007-11)
The purpose of this study was to test whether children and adolescents with anxiety disorders exhibit selective processing of threatening facial expressions in a pictorial version of the emotional Stroop paradigm. Participants ...
Controlling surface morphologies by time-delayed feedback
(American Physical Society, 2007-06-25)
We propose a method to control the roughness of a growing surface via a time-delayed feedback scheme. The method is very general and can be applied to a wide range of nonequilibrium growth phenomena, from solid-state epitaxy ...
Searching for the physiological mechanism of density dependence: Does corticosterone regulate tadpole responses to density?
(University of Chicago Press, 2007-07)
Density-dependent population regulation is important in many natural populations, and in those populations, high population density is a likely stressor. In amphibians, previous laboratory studies with tadpoles suggest ...
Coupling constant behavior of eigenvalues of Zakharov-Shabat systems
(AIP Publishing, 2007-12)
We consider the eigenvalues of the non-self-adjoint Zakharov-Shabat systems as the coupling constant of the potential is varied. In particular, we are interested in eigenvalue collisions and eigenvalue trajectories in the ...
Bound states of hydrogen atom in a theory with minimal length uncertainty relations
(AIP Publishing, 2007-05)
The following properties of bound states of hydrogen atom in a theory with noncommuting position operators are investigated: their number, multiplicities, accidental degeneracy, localization, and dependence on the values ...
