ramadan fasting is one of the most important religious duties of muslims, that its effect on the heart has not been determined yet. our objective was to evaluate the effect of ramadan fasting on ventricular repolarization as assessed by qt interval, corrected qt interval, qt dispersion or corrected qt dispersion. sixthy healthy subjects aged 20 to 35 years were dispersion included in this study...

Contamination of a sampled distribution, for example by a heavy-tailed distribution, can degrade the performance of a statistical estimator. We suggest a general approach to alleviating this problem, using a version of the weighted bootstrap. The idea is to “tilt” away from the contaminated distribution by a given (but arbitrary) amount, in a direction that minimises a measure of the new distri...

The pair-weighted relative velocity dispersion of galaxies provides a measure of the thermal energy of fluctuations of the observed galaxy distribution, but the measure is difficult to interpret and is very sensitive to the existence of rare, rich clusters of galaxies. Several alternative statistical procedures have recently been suggested to relieve these problems. We apply a variant of the ob...

Introduction of data assimilation procedures in the meteorological pre-processor of atmospheric dispersion models used in emergency response systems.

In this paper, a new structure is provided for the dispersion compensating photonic crystal fibers in order to broaden the chromatic dispersion and increase the dispersion compensating capability in a wide wavelength range. In the structure, putting a combination of circular holes and a star structure in the inner core clad causes the dispersion coefficient profile to be broadened, and addition...

Multivariate count data are often modeled via a multivariate Poisson distribution, but it contains an underlying, constraining assumption of equi-dispersion (where its variance equals mean). Real oftentimes over-dispersed and, as such, consider various advancements negative binomial structure. While over-dispersion is more prevalent than under-dispersion in real data, however, examples containi...

The packet pair technique estimates the capacity of a path (bottleneck bandwidth) from the dispersion (spacing) experienced by two back-to-back packets 5]]19]]13]. It has also been claimed that the dispersion of longer packet bursts (`packet trains') can measure the available bandwidth of a path 5]]9]]3]. This paper examines such packet pair and packet train dispersion techniques. We rst demons...

Flooding attack is most challenging security threat in Mobile Adhoc Networks (MANETs). This attack is responsible for reducing the network performance of various routing protocols. In this paper, we will discuss MANETs under the AODV protocol. The existing Flooding attack prevention schemes are not much secure for resistance against flooding attacks. In this article, a new statistical based app...

BACKGROUND Colony formation assay is the gold standard to determine cell reproductive death after treatment with ionizing radiation, applied for different cell lines or in combination with other treatment modalities. Associated linear-quadratic cell survival curves can be calculated with different methods. For easy code exchange and methodological standardisation among collaborating laboratorie...

We briefly review the Trajectory Statistical Methods (TSMs) most used in literature for source identification, essentially based on the concept of Residence Time. Then, we introduce a statistical methodology that, starting from the Concentration Field method, takes into account only the peak values in the concentration time series measured at multiple receptor sites. We use virtual simulations ...
