Carnitine palmitoyl transferase (CPT) 1 A deficiency is a rare disorder of hepatic long-chain fatty acid oxidation. CPT1 deficiency is included in newborn screening programs in a number of countries to allow presymptomatic detection and early treatment of affected...

The hippocampus supports multiple cognitive processes through relational binding and comparison.

Frontiers in human neuroscience

Olsen RK, Moses SN, Riggs L, Ryan JD.

Front Hum Neurosci. 2012 May 25;6:146. doi: 10.3389/fnhum.2012.00146. eCollection 2012.

It has been well established that the hippocampus plays a pivotal role in explicit long-term recognition memory. However, findings from amnesia, lesion and recording studies with non-human animals, eye-movement recording studies, and functional neuroimaging have recently converged upon a...

Interference effects in tone memory.

Memory & cognition

Olson RK, Hanson V.
PMID: 21331864
Mem Cognit. 1977 Jan;5(1):32-40. doi: 10.3758/BF03209189.

Memory for a standard tone in comparison to a subsequent test tone was examined in three experiments with three intervening tones between the standard and test tones. In each trial, the intervening tones were presented from one of seven...

Dynamics of dissociative adsorption of hydrogen on a CO-precovered Ru(0001) surface: a comparison of theoretical and experimental results.

Phys Chem Chem Phys. 2010 Feb 14;12(6):1331-40. doi: 10.1039/b919419c. Epub 2009 Dec 03.

We have studied hydrogen dissociation on a CO-precovered Ru(0001) surface, by means of six-dimensional (6D) quasi-classical and quantum dynamics. The 6D potential energy surface has been built by applying a modified Shepard interpolation method to a set of density...

External Validity in Policy Evaluations that Choose Sites Purposively.

J Policy Anal Manage. 2013;32(1):107-121. doi: 10.1002/pam.21660.

Evaluations of the impact of social programs are often carried out in multiple "sites," such as school districts, housing authorities, local TANF offices, or One-Stop Career Centers. Most evaluations select sites purposively following a process that is nonrandom. Unfortunately,...

A multivariate twin study of early literacy in Japanese Kana.

Learning and individual differences

Fujisawa KK, Wadsworth SJ, Kakihana S, Olson RK, Defries JC, Byrne B, Ando J.

Isotope effect on adsorbed quantum phases: diffusion of H2 and D2 in nanoporous carbon.

Physical review letters

Contescu CI, Zhang H, Olsen RJ, Mamontov E, Morris JR, Gallego NC.

Quasielastic neutron scattering of H(2) and D(2) in the same nanoporous carbon at 10-40 K demonstrates extreme quantum sieving, with D(2) diffusing up to 76 times faster. D(2) also shows liquidlike diffusion while H(2) exhibits Chudley-Elliott jump diffusion, evidence...
