2015/10/16
We study the effect of an external electric field E on macroscopic relaxation laws for crystal surfaces in 2 + 1 dimensions. We derive a nonlinear, fourth-order partial differential equation (PDE) for...
Evaluation of the transfer of Listeria monocytogenes: A study at the macroscopic and cellular level
Monocytes liszt high density polyethylene biofilms cells the nucleus of the cell
2015/1/28
The objective of this work was to study parameters involved in the transfer of Listeria monocytogenes from surfaces to foods and vice versa. We evaluated the influence of surfaces (stainless steel and...

The statistical mechanics of DNA denaturation under fixed linking number is qualitatively different from that of the unconstrained DNA. Quantitatively different melting scenarios are reached from two ...
Probing the Microscopic with the Macroscopic: from Properties of Star Cluster Systems to Properties of Cluster-Forming Regions
Macroscopic: Properties Cluster Systems Cluster-Forming Regions
2011/10/11
To understand how systems of star clusters have reached their presently observed properties constitutes a powerful probe into the physics of cluster formation, without needing to resort to high spatia...
Students' Views of Macroscopic and Microscopic Energy in Physics and Biology

2011/9/7
Energy concepts are fundamental across the sciences, yet these concepts can be fragmented along disciplinary boundaries, rather than integrated into a coherent whole. To teach physics effectively to b...
Frictional damping in radiative electrodynamics and its scaling to macroscopic systems
Abraham-Lorentz-Dirac equation, radiation force, Unruh radiation,frictional dissipation
2011/8/30
Radiation force in Abraham-Lorentz-Dirac equation is revisited for possible signature of irreversible action in the dynamics. The analysis shows that the classical electron can ‘dissipate’ out a certa...
