Many studies have shown that the deductive inferences that people make have global properties that reflect the statistical information implicit in the premises. This suggests that such reasoning can be explained by a single, underlying probabilistic model. In contrast, the dual-process model of conditional reasoning (Verschueren, Schaeken, & d'Ydewalle, 2005b) ...

The imitation of translation, as mediated by internal ribosome entry sites, has not yet been reported in Pichia pastoris. An IRES element from Saccharomyces cerevisiae was demonstrated to direct the translation of a dicistronic mRNA in P. pastoris. The 5'-untranslated region of GPR1 mRNA, termed GPR, was cloned into a ...

Tetranychus urticae (Acari: Tetranychidae) is a phytophagous mite that forms huge colonies. All active members of a colony (immatures and matures, females and males) spin silken threads. These mites construct a common web that protects the colony from external aggression. The silk coverage is well-known to provide advantages to the ...

Clinical trials usually use the relative risk (rate ratio or hazard ratio) to compare the effects of one treatment modality with others. However, the numbers needed to treat/harm (NNT/NNH) are sometimes used as another way of presenting an estimate of the effect of a medical intervention, pointing at the number ...

The physical mapping of single locus sequences by tyramide-fluorescence in situ hybridization (Tyr-FISH) and the analysis of sequences obtained from microdissected chromosomes were assayed as potential tools for (1) determining homology and homoeology among chromosome regions of Avena species, and (2) establishing associations between linkage groups and specific chromosomes.
