In this paper, we present a novel algorithm for adaptive fuzzy segmentation of MRI data and estimation of intensity inhomogeneities using fuzzy logic. MRI intensity inhomogeneities can be attributed to imperfections in the RF coils or some problems associated with the acquisition sequences. The result is a slowly-varying shading artifact over the image that can produce errors with conventional ...

P a t i e n t s 738 patients (mean age 57 y, 55% men) with ≥ 1 episode of unprovoked VTE (defined as objectively confirmed, symptomatic, proximal deep venous thrombosis or pulmonary embolism that occurred in the absence of a major risk factor for thrombosis) who had completed ≥ 3 months of oral anticoagulant therapy at the conventional intensity. Exclusion criteria were other indications for wa...

Physical training influences the cells and mediators involved in skin wound healing. The objective of this study was to determine the changes induced by different intensities of physical training in mouse skin wound healing. Ninety male C57BL6 mice (8 weeks old, 20-25 g) were randomized into three physical training groups: moderate (70% VO2max), high (80% VO2max), and strenuous intensity (90% V...

We give a necessary and sufficient condition for a function E(t) being of minimum phase, and hence for its phase being univocally determined by its intensity |E(t)|. This condition is based on the knowledge of E(t) alone and not of its analytic continuation in the complex plane, thus greatly simplifying its practical applicability. We apply these results to find the class of all band-limited si...

Raeini breed is the most productive Cashmere goat in Iran. Helminthes infections cause major economiclosses globally to the livestock industries and farming communities. The objective of this study was todetermine the seasonal prevalence and intensity of Eimeria and gastrointestinal helminth parasitic infectionsin Raeini goats in Iran. A total of 438 faecal samples were randomly taken from clin...

INTRODUCTION The prevalence of adolescent electronic cigarette (e-cigarette) use has increased in most countries. This study aims to determine the relation between the frequency of e-cigarette use and the frequency and intensity of cigarette smoking. Additionally, the study evaluates the association between the reasons for e-cigarette use and the frequency of its use. MATERIALS AND METHODS Us...

We report a femtosecond transient absorption spectroscopic study on the (6, 5) single-walled carbon nanotubes and the (7, 5) inner tubes of a dominant double-walled carbon nanotube species. We found that the dynamics of exciton relaxation probed at the first transition-allowed state (E(11)) of a given tube type exhibits a markedly slower decay when the second transition-allowed state (E(22)) is...
