Numerical Convergence Of Gyrokinetic Simulations Of Ion-Temperature-Gradient Turbulence (2007)

A. M. Dimits, D. E. Shumaker, W.M. Nevins, B.I. Cohen, S.E. Parker

oning representations, along with rapid increases in computer power have greatly increased the applicability and solidity of gyrokinetic simulations for fusion relevant plasma conditions. Even with...

Kinetic-Ion Simulations Addressing Whether Ion Trapping Inflates Stimulated Brillouin Backscattering Reflectivities (2007)

Cohen, B. I., Williams, E. A., Vu, H. X.

An investigation of the possible inflation of stimulated Brillouin backscattering (SBS) due to ion kinetic effects is presented using electromagnetic particle simulations and integrations of...

LAWRENCE LIVERMORE NATIONAL LABORATORY Preprint UCRL-JC-117113 FIFTEENTH INTERNATIONAL CONFERENCE ON PLASMA PHYSICS AND CONTROLLED NUCLEAR FUSION RESEARCH (1994)

Seville Spain, A. M. Dimits, J. A. Byers, T. J. Williams, B. I. Cohen, X. Q. Xu, ...

Results are presented from the first systematic nonlinear kinetic simulation study of the scalings and parameter dependences of toroidal ion-temperature-gradient (ITG) turbulence and transport, and...

Inactivation of contraceptive steroid hormones by human intestinal clostridia.

Bokkenheuser, V D, Winter, J, Cohen, B I, O'Rourke, S, Mosbach, E H

Steroid hormones reduced in ring-A are devoid of hormonal activity. In metabolic experiments we found that human fecal flora reduced the delta 4-3-keto structure of natural progestins to 3...

Origins of structural diversity within sequentially identical hexapeptides.

Cohen, B. I., Presnell, S. R., Cohen, F. E.

Efforts to predict protein secondary structure have been hampered by the apparent structural plasticity of local amino acid sequences. Kabsch and Sander (1984, Proc. Natl. Acad. Sci. USA 81,...
