Paramagnetic Spin Correlations in Colossal Magnetoresistive La 0.7 Ca 0.3 MnO 3

April 2, 2012

Joel Helton, Matthew B. Stone, Dmitry A. Shulyatev, Yakov M. Mukovskii, Jeffrey W. Lynn
Neutron spectroscopy measurements reveal dynamic spin correlations throughout the Brillouin zone in the colossal magnetoresistive system La 0.7Ca 0.3MnO 3 at 265 K ({approx}1.03T c). The long-wavelength behavior is consistent with spin diffusion, yet an

Workflow and Electronic Health Records in Small Medical Practices

Mala Ramaiah, Eswaran Subrahmanian, Ram D. Sriram, Bettijoyce B. Lide
This paper analyzes the workflow and implementation of electronic health record (EHR) systems across different functions in small physician offices. We characterize the differences in the offices based on the levels of computerization in terms of workflow

Mechanisms of free radical-induced damage to DNA

April 1, 2012

M Miral Dizdar, Pawel Jaruga
Endogenous and exogenous sources cause free radical-induced DNA damage in living organisms by a variety of mechanisms. The highly reactive hydroxyl radical reacts with the heterocyclic DNA bases and the sugar moiety near or at diffusion-controlled rates by

Neutron Studies of Tb 2 Mo 2 O 7

April 1, 2012

Jason S. Gardner, G. Ehlers, S. O. Diallo
We have used the new high energy resolution spectrometer (BaSis), at the Spallation Neutron Source in Oak Ridge, to conclusively prove the existence of a low energy mode at 0.34(1) meV in the spin glass Tb 2mo 2O 7. This mode is reminiscent of the
