Matching derived functionally-same stimulus relations: equivalence-equivalence and classical analogies
(Springer Nature, 2004-04-01)
Previous studies have shown that, after being trained on A-B and A-C matching tasks, subjects match not only functionally-same B and C stimuli (stimulus equivalence), but also BC compounds with same-class elements and BC ...
Constraints on the very high energy emission from bl lacertae objects
(IOP Publishing, 2004-03-01)
We present results from observations of 29 BL Lacertae objects, taken with the Whipple Observatory 10 m gamma-ray telescope between 1995 and 2000. The observed objects are mostly at low redshift (z<0.2), but observations ...
High prevalence of helicobacter species detected in laboratory mouse strains by multiplex pcr-denaturing gradient gel electrophoresis and pyrosequencing
(American Society for Microbiology, 2004-08-01)
Rodent models have been developed to study the pathogenesis of diseases caused by Helicobacter pylori, as well as by other gastric and intestinal Helicobacter spp., but some murine enteric Helicobacter spp. cause hepatobiliary ...
