Background: Recent studies have found some genetic variants as a risk factor for autoimmune diseases such as Multiple Sclerosis (MS). Cluster of Differentiation 226 (CD226) is one of the risk factors for MS.  Objectives: The present study aimed to evaluate the gene expression of CD226, and its protein serum level in peripheral blood samples of MS patients and healthy individuals. Materials & ...

In many cluster analysis applications, data can be composed of a number of feature subsets where each is represented by a number of diverse mixture model-based clusters. However, in most feature selection algorithms, this kind of cluster structure has been less interesting because they accounted for discovery of a single informative feature subset for clustering. In this study, we attempt to re...

A unique 1-D chain of sodium cluster containing (Na6) rings stabilized by a molybdenum containing metalloligand has been synthesized and characterized and the DFT calculations show striking resemblance in their aromatic behaviour with the corresponding hydrocarbon analogues.

We simulated structural and dynamical properties of imidazoles tethered to aliphatic backbones to determine how chain length influences the competition between extended hydrogen-bond networks and imidazole reorientation dynamics. We performed molecular dynamics simulations on hypothetical solids using the GAFF Amber force field over the temperature range 300-800 K, for chain lengths varying fro...

We present in this paper an investigation of a special class of wireless sensor networks for monitoring critical infrastructures that may extend for hundreds of miles in distances. Such networks are fundamentally different from traditional sensor networks in that the sensor nodes in this class of networks are deployed along narrowly elongated geographical areas and form a chain-type topology. B...

Near-future SZ surveys such as ACT, SPT, APEX, and Planck will soon find thousands of galaxy clusters. Multi-frequency arcminute-resolution SZ observations can, in principle, determine each cluster’s gas temperature (Te), bulk velocity (vpec), and optical depth (τ). However, the frequency bands and detector sensitivity employed by upcoming surveys will generally not be sufficient to disentangle...

This research aims to determine the existence of inflection points when companies’ credit risk goes from being minimal (Hedge) high (Ponzi). We propose an analysis methodology that determines probability hedge credits migrate speculative and then Ponzi, through simulations with homogeneous Markov chains k-means clustering method thresholds migration among clusters. To prove this, we used quarte...

Most research on predicting community evolution focuses changes in the states of communities. Instead, we focus individual nodes and define novel problem whether a specific node stays same cluster, moves to another cluster or drops out network. We explore variations propose appropriate classification features based local global measures. Motivated by prevalence machine learning approaches embed...

Iron-sulfur (Fe-S) clusters are essential for numerous biological processes, including mitochondrial respiratory chain activity and various other enzymatic and regulatory functions. Human Fe-S cluster assembly proteins are frequently encoded by single genes, and inherited defects in some of these genes cause disease. Recently, the spectrum of diseases attributable to abnormal Fe-S cluster bioge...
