Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

On a Logistic Approximation to the Normal and Other Cumulative Distribution Functions
Recoletos Multidisciplinary Research Journal, 2014 This paper proposes an approach that maintains the simplicity of various approximations as well as having a closed- form algebraic inverse yet easily generalizable to the approximation of other cumulative distribution functions.

A proposal for a different chi-square function for Poisson distributions
, 1999 We obtain an approximate Gaussian distribution from a Poisson distribution after doing a change of variable. A new chi-square function is obtained which can be used for parameter estimations and goodness-of-fit testing when adjusting curves to histograms.

Biostatistics series module 4: Comparing groups - categorical variables
Indian Journal of Dermatology, 2016 Categorical variables are commonly represented as counts or frequencies. For analysis, such data are conveniently arranged in contingency tables. Conventionally, such tables are designated as r × c tables, with r denoting number of rows and c denoting ...

A Method of CHI-square Feature Selection Based on Probability [PDF]
Jisuanji gongcheng, 2016 Traditional CHI-square feature selection method does not take into account the category number of words in imbalanced data sets,the frequency of words,the intra-class and inter-class distribution of words,so that it fails to choose valid feature words ...

Properties and numerical evaluation of the Rosenblatt distribution [PDF]
, 2013 This paper studies various distributional properties of the Rosenblatt distribution. We begin by describing a technique for computing the cumulants. We then study the expansion of the Rosenblatt distribution in terms of shifted chi-squared distributions.

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
