There are perfect construction formulas for the orthonormal uniwavelet. However, it seems that there is not such a good formula with similar structure for multiwavelets. Especially, construction of multiwavelets with dilation factor a(a ≥ 2, a ∈ Z) lacks effective methods. In this paper, a procedure for constructing compactly supported orthonormal multiscale functions is first given, and then b...

V ehkavaara et al. (1) demonstrated that impaired endothel iumdependent arterial dilation characterizes patients with impaired fasting glucose (IFG). The purpose of the study was to investigate the effects of exercise training on endothelium-dependent arterial dilation in subjects with IFG using noninvasive measurement of flowmediated, endothelium-dependent dilation of the brachial artery.

Vasodilation to increases in flow was studied in isolated gracilis muscle arterioles of female endothelial nitric oxide synthase (eNOS)-knockout (KO) and female wild-type (WT) mice. Dilation to flow (0-10 microl/min) was similar in the two groups, yet calculated wall shear stress was significantly greater in arterioles of eNOS-KO than in arterioles of WT mice. Indomethacin, which inhibited flow...

The orienting reflex is initiated by a salient stimulus and facilitates quick, appropriate action. It involves a rapid shift of the eyes, head, and attention and other physiological responses such as changes in heart rate and transient pupil dilation. The SC is a critical structure in the midbrain that selects incoming stimuli based on saliency and relevance to coordinate orienting behaviors, p...

OBJECTIVE The purpose of this study was to compare the cost-effectiveness of dilation and evacuation versus misoprostol induction of labor for second-trimester termination. STUDY DESIGN Using decision analysis, we compared the cost-effectiveness of dilation and evacuation and misoprostol induction of labor for second-trimester termination. Complications for dilation and evacuation and inducti...

Endothelial dysfunction that can be detected as impaired flow-mediated dilation by ultrasonography is an early event in atherogenesis and has been demonstrated in healthy subjects with risk factors for atherosclerosis many years before the appearance of atheromatous plaques. We examined the influence of physical training on flow-mediated dilation in patients with the polymetabolic syndrome. Twe...

Because pial artery dilation during a 20- or 40-min hypoxic exposure was less than that observed during a 5- or 10-min exposure, stimulus duration determines the vascular response to hypoxia. Dynorphin (Dyn) modulates hypoxic pial dilation and contributes to decremented dilation during longer hypoxic exposures. This study was designed to determine whether vasopressin (VP) contributes to Dyn mod...

The goal of this study was to detect the level of arousal induced by pictures of negative, positive and neutral affective valence by measuring the pupil dilation of 4 subjects. In order to detect arousal from pupil dilation data, it was necessary to reduce the effect of luminance. This required comparing the picture luminance measures to the collected pupil dilation data, and applying additiona...

~ Integer dilation and contraction are functions used in conjunction with quadtree and octree mapping systems. Dilation is the process of inserting a number of zeros before each bit in a word and contraction is the process of removing those zeros. Present methods of dilation and contraction involve lookup tables which consume considerable amounts of memory for mappings of large or high resoluti...

BACKGROUND Esophageal dilation by rendezvous is a useful technique for the treatment of complicated esophageal strictures. METHODS AND RESULTS We present a case of a 74-year-old man with chronic dysphagia caused by a complete cervical esophageal stricture that developed after external beam radiotherapy for treatment of papillary thyroid carcinoma. During attempted dilation using the rendezvou...
