The increasing amount of digital audio-visual content accessible today calls for scalable solutions for content based search. The state of the art solutions reveal linear scalability in respect to the collection size due to the large number of distance computations needed for comparing low level audio-visual features. As a result, search in large audio-visual collections is limited to associate...

Abstract: In this paper a new topology of high step-down dc-dc converter is proposed. The proposed converter uses an interleaved structure with one phase using a traditional buck converter and the second phase uses its inverted version. By this technique a high step down voltage conversion can be achieved as compared to the traditional interleaved buck converter. Operating principle and steady ...

Human size changes over time with worldwide secular trends in height, weight, and body mass index (BMI). There is general agreement to relate the state of nutrition height ratios weight-to-height. The BMI a ratio. It commonly used classify underweight, overweight obesity adults. Yet, inappropriate provide any immediate information on composition.
 accepted that “a simple adults”. stated “p...

Double-stranded RNA (dsRNA) can induce post-transcriptional gene silencing in a wide variety of organisms. Commonly, inverted repeats are used to produce dsRNA to silence genes of interest. However, cloning inverted repeats still remains a rate-limiting step for widely applying this technique. Here we describe a pGEM-T-based vector, pGEM-WIZ, designed to produce inverted repeats for any Drosoph...

The inverted repeated sequences (foldback DNA) of yeast nuclear DNA have been examined by electron microscopy and hydroxyapatite chromatography. Of the inverted repeat structures seen in the electron microscope, 34% were hairpins and 66% had a single stranded loop at the end of a duplex stem. The number average length of the repeat was 0.3 kb and the single stranded loop was 1.6 kb. It is estim...

introduction: leptin, secreted from adipose tissue may have some correlation with coronary artery disease according to some reports in literature. the mean concentration of plasma leptin in patients with normal and abnormal myocardial perfusion imaging (mpi) and relation of leptin levels, independently to abnormality in mpi after correction for body mass index (bmi) was evaluated. methods: as a...

obesity is the common clinical signs in hirsutism, which can cause metabolic disturbances like dyslipidemia, insulin resistance and hypertension. to investigate relationship of overweight and obesity with hormonal and metabolic parameters in suspected hirsute women, in a cross-sectional study, 184 suspected hirsute women were selected in a reproductive endocrinology outpatient clinic in north o...

introduction: the purpose of the present study was to evaluate anthropometric characteristics of weight, sitting & standing height, cormic index and bmi in the adult residents of qazvin, iran. methods: in this cross-sectional study, 300 adult inhabitants aged 18-55 years (180 males and 120 females) of qazvin, iran were evaluated. the participants were selected randomly and without any physical ...

introduction: leptin is an adipocyte-derived hormone. exogenous leptin allows the recovery of the reproductive function. in humans, leptin correlates positively with the body mass index (bmi). the aim of this study was to investigate the association of leptin with the toxic effects of iron overload. methods: 219 major beta thalassemic patients (119 men, 100 women) and 137 non thalassemic indivi...
