BACKGROUND Wake-up stroke (WUS) represents 25% of all ischemic strokes. There is conflicting evidence concerning clinical severity, imaging characteristics, and outcome when WUS is compared with stroke of known time of onset. Our aim was to compare WUS patients with patients with ischemic stroke within the therapeutic window (STW) for thrombolysis. METHODS This is a retrospective hospital-bas...

An automatic process for estimating ground stability and settlement of circular tunnels is developed practitioners in this paper using finite difference method FLAC code. The numerical model aims to simulate the movement relaxation soil around shield lining annulus that occurs due overcutting grouting tunnel void by a boring machine. To achieve this, uses pressure technique progressively reduce...

The sit-to-walk (STW) movement is a functional task that challenges balance and co-ordination. There is a paucity of literature investigating the phases of this movement and its significance in a clinical rehabilitation context. Measuring phases of this movement may provide clinically applicable data for screening subjects for mobility problems and evaluating interventions. Fifty-six subjects f...

Objective We tested the claim that age-related increases in knowledge interfere with word retrieval, leading to word finding failures. We did this by relating a measure of crystallized intelligence to tip-of-the-tongue (TOT) states and picture naming accuracy. Method Participants were from a large (N = 708), cross-sectional (aged 18-88 years), population-based sample from the Cambridge Cent...

Introduction: This contribution explores the mapping of spectral parameters of lunar features using the Clementine UVVIS+NIR data set covering the wavelength range between 415 and 2000 nm [1]. The extracted spectral features are the minimum and depth of the principal absorption trough near 1000 nm and the corresponding values of secondary absorption features present at higher wavelengths, as we...

Information on the effect of long-term management on soil nutrients and chemical properties is scanty. We examined the 30-year effect of tillage frequency and cropping sequence combination on dryland soil Olsen-P, K, Ca, Mg, Na, SO4-S, and Zn concentrations, pH, electrical conductivity (EC), and cation exchange capacity (CEC) at the 0-120 cm depth and annualized crop yield in the northern Great...

In vessel performance analysis, reliable information about speed-through-water (STW) is key for realistic modeling of the single ship’s fuel efficiency. It paramount that STW measurements are such they can be adopted as input in consumption forecast models. This paper presents a study where three variations Dynamic Factor Model used to estimate STW. A simulation presented demonstrate estimation...

Cancrinite, sodalite, and zeolite A have been found to form upon contacting hyperalkaline simulated tank waste (STW) with vadose zone sediments from the Hanford Reservation. Here, soluble silica and STW are used to study mineral formation and transformation. Two Hanford sediment fractions (diameters <50 and >50 lm instead of soluble silica) are also used as silica sources for comparison. A seri...

Proper estimation of foundation settlement is a crucial factor in designing shallow foundations. Recent literature shows the applicability of Artificial Neural Networks (ANNs) in predicting the settlement of shallow foundations. However, conventional ANNs have some drawbacks: getting trapped in local minima and a slow rate of learning. Utilization of an optimization algorithm such as Particle S...

The transmission and prevalence of Human Immunodeficiency Virus (HIV) among those employed as sex trade workers (STW) is a major public health concern. The present study describes the self-reported responses of 340 STW, at-risk for contracting HIV. The participants were recruited by selective targeting between 2009 and 2010 from within the Saskatoon Health Region (SHR), Saskatchewan, Canada. As...
