When multiple stimulus-to-response (S-R) mappings are randomly intermixed and repeated in a block of trials, immediate repetitions of an aspect of a stimulus and/or a response can facilitate stimulus detection, classification, and/or response selection--known as sequential priming. In addition to these short-term effects, response times (RT) for almost any task diminish with extended practice, ...

development of potent new anti-shigella agents for rapid and specific detection and treatment is of great importance. aptamers, nucleic acid oligomers capable of specific binding to a wide range of non-nucleic acid targets, may be of value for this purpose. in the present study, we used a systematic evolution of ligands by exponential enrichment (selex) process to select dna aptamers that b...

In one of the first experiments about the use of NHST (Rosenthal and Gaito, 1963), researchers in psychology were asked expressions of degree of belief in the hypothesis of an effect as a function of the associated p levels and sample sizes. The authors emphasized a “cliff effect” for the .05 level for which the degree of belief was quite the same as for the .03 level, and came to the conclusio...

Recent research has showed that invariant indexing can speed up the recognition process in computer vision. Extraction of invariant features can be done by choosing rst a canonical reference frame, and then features in this reference frame. These automatically become invariants. In this paper methods are given where a global and stable approach is used both in choosing the canonical reference f...

Hilbert’s two-dimensional space-filling curve is appreciated for its good locality-preserving properties and easy implementation for many applications. However, Hilbert did not describe how to generalize his construction to higher dimensions. In fact, the number of ways in which this may be done ranges from zero to infinite, depending on what properties of the Hilbert curve one considers

PURPOSE: Urine sampling has previously been evaluated for detecting dehydration in young male athletes. The present study investigated whether urine analysis can serve as a measure of dehydration in men and women of a wide age span. METHODS: Urine sampling and body weight measurement were undertaken before and after recreational physical exercise (median time: 90 minutes) in 57 volunteers aged ...
