A case-crossover study of laceration injuries in pork processing

Occupational and Environmental Medicine, 2012
The authors estimated the associations between transient risk factors and laceration injuries in workers at two meatpacking plants in the Midwest.The case-crossover design was used to collect within-subject transient work task and personal-level exposure information.

Differentiating the impact of fine and coarse particulate matter on cause-specific cerebrovascular mortality: An individual-level, case-crossover study

Ecotoxicology and Environmental Safety
Background and objectives: Many studies suggested that short-term exposure to fine particulate matter (PM2.5) and coarse particulate matter (PM2.5–10) was linked to elevated risk of cerebrovascular disease.

Magnetic oscillations of critical current in intrinsic Josephson-junction stacks

, 2007
A key phenomenon related to the Josephson effect is oscillations of different properties of superconducting tunneling junctions with magnetic field. We consider magnetic oscillations of the critical current in stacks of intrinsic Josephson junctions ...

Coherent and incoherent dynamics in excitonic energy transfer: correlated fluctuations and off-resonance effects [PDF]

, 2011
We study the nature of the energy transfer process within a pair of coupled two-level systems (donor and acceptor) subject to interactions with the surrounding environment.

Number fluctuations in cold quantum gases

, 2007
In ultracold gases many experiments use atom imaging as a basic observable. The resulting image is averaged over a number of realizations and mostly only this average is used. Only recently the noise has been measured to extract physical information.

Chaos and energy spreading for time-Dependent Hamiltonians, and the various Regimes in the theory of Quantum Dissipation

, 2000
We make the first steps towards a generic theory for energy spreading and quantum dissipation. The Wall formula for the calculation of friction in nuclear physics and the Drude formula for the calculation of conductivity in mesoscopic physics can be ...

Nonequilibrium characteristics in all-superconducting tunnel structures

, 2006
We study the nonequilibrium characteristics of superconducting tunnel structures in the case when one of the superconductors is a small island confined between large superconductors. The state of this island can be probed for example via the supercurrent
