BACKGROUND AND PURPOSE Cross-sectional studies describe a positive association between common carotid artery intima-media thickness (CCA-IMT) and carotid plaques (CP). However, longitudinal data on the predictive value of CCA-IMT for occurrence of CP are limited. Therefore, the role of increasing CCA-IMT in the atherosclerotic process is still discussed controversially. METHODS We investigate...

BACKGROUND The present study was conducted to estimate 10-year cardiovascular disease events (CVD) risk using three instruments in northern Iran. MATERIAL AND METHODS Baseline data of 3201 participants 40-79 of a population based cohort which was conducted in Northern Iran were analyzed. Framingham risk score (FRS), World Health Organization (WHO) risk prediction charts and American college o...

Formal analysis of the emergent structural properties of dynamic networks is largely uncharted territory. We focus here on the properties of forward reachable sets (FRS) as a function of the underlying degree distribution and edge duration. FRS are defined as the set of nodes that can be reached from an initial seed via a path of temporally ordered edges; a natural extension of connected compon...

We report on the spectroscopic study of 19 low luminosity Flat Radio Spectrum (LL FRS) sources selected from Marchã's et al. (1996) 200 mJy sample. In the optical, these objects are mainly dominated by the host galaxy starlight. After correcting the data for this effect, we obtain a new set of spectra clearly displaying weak emission lines; such features carry valuable information concerning th...

BACKGROUND/AIMS The AIMS65 score has not been sufficiently validated in Korea. The objective of this study was to compare the AIMS65 and other scoring systems for the prediction of various clinical outcomes in Korean patients with acute nonvariceal upper gastrointestinal bleeding (NVUGIB). METHODS The AIMS65 score, clinical and full Rockall scores (cRS and fRS) and Glasgow-Blatchford (GBS) sc...

The Hotelling's  control chart, is the most widely used multivariate procedure for monitoring  two or more related quality characteristics, but it’s power lacks the desired performance in detecting small to moderate shifts. Recently, the variable sampling intervals (VSI) control scheme in which the length of successive sampling intervals is determined upon the preceding values has been proved t...

The conversion from functional requirements (FRs) to design parameters is the foundation of product customization. However, original customer needs usually result in incomplete FRs, limited by customers’ incomprehension on these products. As FRs may undermine activities afterwards, managers need develop an effective approach predict missing values FR. This study proposes integrative obtain comp...

Fungal rhinosinusitis (FRS) is a rarely encountered disease; however, the incidence increasing. It has strong association with impaired immune system of host as well suitable environment for fungal growth. spores are abundant in surroundings and can enter nasal airway paranasal sinuses (PNS) through inhalation; only small number patients develop FRS. The primary organisms responsible FRS Asperg...

In vitro studies performed on brain slices demonstrate that the potassium channel blocker 4-aminopyridine (4AP, 50 microM) discloses electrographic seizure activity and interictal discharges. These epileptiform patterns have been further analyzed here in a isolated whole guinea pig brain in vitro by using field potential recordings in olfactory and limbic structures. In 8 of 13 experiments runs...

An algebraic integer (AI) based time-multiplexed row-parallel architecture and two final-reconstruction step (FRS) algorithms are proposed for the implementation of bivariate AI-encoded 2-D discrete cosine transform (DCT). The architecture directly realizes an error-free 2-D DCT without using FRSs between row-column transforms, leading to an 8×8 2-D DCT which is entirely free of quantization er...
