Resonant impurity bands in semiconductor superlattices.

Physical review letters

Stehr D, Metzner C, Helm M, Roch T, Strasser G.
PMID: 16384504
Phys Rev Lett. 2005 Dec 16;95(25):257401. doi: 10.1103/PhysRevLett.95.257401. Epub 2005 Dec 12.

It is shown that the confined impurity state of a semiconductor quantum well develops into an excited impurity band in the case of a superlattice. This is studied by following theoretically the transition from a single to a multiple...

Phys Rev E Stat Nonlin Soft Matter Phys. 2010 Sep;82(3):031114. doi: 10.1103/PhysRevE.82.031114. Epub 2010 Sep 09.

In many applications one is interested in finding a simplified model which captures the essential dynamical behavior of a real life process. If the essential dynamics can be assumed to be (approximately) memoryless then a reasonable choice for a...

Problematic use of prescription-type opioids prior to heroin use among young heroin injectors.

Substance abuse and rehabilitation

Pollini RA, Banta-Green CJ, Cuevas-Mota J, Metzner M, Teshale E, Garfein RS.
PMID: 23293547
Subst Abuse Rehabil. 2011 Oct;2(1):173-180. doi: 10.2147/SAR.S24800.

BACKGROUND: Misuse of prescription-type opioids and related adverse health effects are increasing, but little is known about the role of these drugs as a precursor to heroin use. We conducted an exploratory study to determine the proportion of young...

Bacterial Degradation of Quinoline and Derivatives-Pathways and Their Biocatalysts.

Angewandte Chemie (International ed. in English)

Fetzner S, Tshisuaka B, Lingens F, Kappl R, Hüttermann J.
PMID: 29711093
Angew Chem Int Ed Engl. 1998 Mar 16;37(5):576-597. doi: 10.1002/(SICI)1521-3773(19980316)37:5<576::AID-ANIE576>3.0.CO;2-L.

A series of interesting enzymes were discovered during investigations on the degradation of quinoline by microorganisms. These include the molybdenum-containing hydroxylases that catalyze the transformation 1→2 and the unusual 2,4-dioxygenases that catalyze the reaction 3→4. The application of the...

Keep It Flexible: Driving Macromolecular Rotary Motions in Atomistic Simulations with GROMACS.

Journal of chemical theory and computation

Kutzner C, Czub J, Grubmüller H.

J Chem Theory Comput. 2011 May 10;7(5):1381-1393. doi: 10.1021/ct100666v. Epub 2011 Mar 31.

We describe a versatile method to enforce the rotation of subsets of atoms, e.g., a protein subunit, in molecular dynamics (MD) simulations. In particular, we introduce a "flexible axis" technique that allows realistic flexible adaptions of both the rotary...
