The gravitational lens CLASS B1608+656 is the only four-image lens system for which all three independent time delays have been measured. This makes the system an excellent candidate for a high-quality determination of H0 at cosmological distances. However, the original measurements of the time delays had large (12–20%) uncertainties, due to the low level of variability of the background source...

length of hospital stay (los) is a key indicator for hospital management. reducing hospital stay is a priority for all health systems. we aimed to determine the length of hospital stay following coronary artery bypass surgery (cabg) based on its clinical and non-clinical factors. a cross-sectional study of 649 consecutive patients who underwent coronary artery bypass graft surgery was conducted...

background: it is necessary to consider into hospital emergency services' quantity and quality in different aspects such as time-to-provider, left-without-treatment and length-of-stay. the aimof this research was to identify the effect of these factors on patient satisfaction in training hospitals. methods: in this descriptive-analytical and cross-sectional study, the sample size was calculated...

introduction : it is clear that if the discharge process takes less time and the patient leaves the hospital bed earlier, the length of hospitalization, and consequently, the waiting time for admission decreases. therefore, the method of use of treatment facilities is somewhat improved. the hospital discharge process, from when the discharge authorization is issued until the patient leaves the ...

INTRODUCTION Delayed patient admission to the intensive care unit (ICU) due to lack of bed availability is a common problem, but the effect on patient outcome is not fully known. METHODS A retrospective study was performed using departmental computerised records to determine the effect of delayed ICU admission and temporary management within the operating theatre suite on patient outcome. Eme...

We consider a closed Nutrient-Phytoplankton-Zooplankton (NPZ) model that allows for a delay in the nutrient recycling. A delay-dependent conservation law allows us to quantify the total biomass in the system. With this, we can investigate how a planktonic ecosystem is affected by the quantity of biomass it contains and by the properties of the delay distribution. The quantity of biomass and the...

This paper proposes a fixed-length routing method based on the color-coding algorithm. In recent LSI system design, exact signal propagation delay is required because of the growth of the operation frequency. To control the delay, the fixed-length routing is widely used. This paper proposes a fixed-length routing method based on the color-coding algorithm. We analyze the complexity of the propo...

in order to find out suitable organic fertilizers for elimination of chemical fertilizers usage and the optimum sowing date in pot marigold cultivation, an experiment was conducted in the agricultural research station, ferdowsi university of mashhad, iran, in 2007 growing season. for this purpose a split plot experiment based on completely randomized block design with three replications was use...

introduction the movement and fate of solutes in the subsurface in affected by a large number of physical, chemical processes requiring a broad array of mathematical and physical sciences to study and describe solute transport. the dispersion is an important parameter in the advection – dispersion equation, which is used in assessing, and solving the problems related to the contamination and th...

In a graying world, there is an increasing interest in correlates of aging, especially those found in early life. Leukocyte telomere length (LTL) is an emerging marker of aging at the cellular level, but little is known regarding its link with poor decision making that often entails being overly impatient. Here we investigate the relationship between LTL and the degree of impatience, which is m...
