BACKGROUND AND OBJECTIVES Ambulatory arterial stiffness index (AASI) is well known as a predictor of cardiovascular mortality in hypertensive patients. Mathematically, AASI reflect the standard deviation (SD) of blood pressure (BP) variation. AASI is measured higher levels in non-dipper than dipper. Thus, AASI has a possibility of not only reflecting arterial stiffness but also BP variability a...

In this paper we prove the Dipper–James conjecture that the centre of the Iwahori–Hecke algebra of type A is the set of symmetric polynomials in the Jucys–Murphy operators. © 2006 Elsevier Inc. All rights reserved.

Previous research employing a real-time auditory perturbation paradigm has shown that talkers monitor their own speech attributes such as fundamental frequency, vowel intensity, vowel formants, and fricative noise as part of speech motor control. In the case of vowel formants or fricative noise, what was manipulated is spectral information about the filter function of the vocal tract. However, ...

OBJECTIVE To assess whether nocturnal blood pressure dipping status in type 1 diabetes is correlated with specific sleep characteristics and differences in nocturnal glycemic profiles. RESEARCH DESIGN AND METHODS Twenty type 1 diabetic adult patients underwent sleep studies with simultaneous 24-h ambulatory blood pressure monitoring and continuous nocturnal glucose monitoring. RESULTS Altog...

20 Flicker perception was investigated using two-alternative forced-choice detection and discrimination tasks with four different 21 types of external noise: (1) broadband noise, (2) 5-Hz notched-noiseVbroadband noise with a 5-Hz band centered on the 22 signal frequency removed, (3) 10-Hz notched-noise, and (4) no external noise. The signal was a burst of 10-Hz sinusoidal 23 flicker presented i...

Contrary to the story of the star-counter in Le Petit Prince, there aren’t unnumerable stars in the night sky, at least so far as we can see with our own eyes. Only about a thousand are visible. Almost all have names or Greek letter designations as part of constellations that anyone can learn to recognize. Modern astronomers have divided the sky into 88 constellations, many of them fictitious— ...

It has been suggested that blur and contrast discrimination thresholds are limited by a common stage of contrast energy transduction, and that this explains the characteristic "dipper" functions found for contrast and blur discrimination. To test this conjecture, thresholds for discriminating increments from decrements in sharpness/blur, and similarly for contrast, were measured using the same ...
