As many as 59% of the transcription factors in Escherichia coli regulate the transcription rate of their own genes. This suggests that auto-regulation has one or more important functions. Here, one possible function is studied. Often the transcription rate of an auto-regulator is also controlled by additional transcription factors. In these cases, the way the expression of the auto-regulator re...

Practical implementation of cardiovascular magnetic resonance (CMR) for the noninvasive screening of atherosclerosis is limited by inter-and intra-observer variability and labor intensity of morphometric analysis by manual planimetry (MANU). We assessed the hypothesis that a semi-automated quantification program (AUTO) for CMR would be faster and more accurate than MANU without loss of reliabil...

purpose of this study is analysis of spatial auto-correlation of freezing changes of iran over the last half century. daily temperature data over the period 1340 - 1383 of esfezari database provided by doctor masoodian (to enhance the temporal resolution of the database, daily observations of temperature from 1383 to the end of 1390 using the same method and the same spatial resolution is added...

Abstract Human action classification is a dynamic research topic in computer vision and has applications video surveillance, human–computer interaction, sign-language recognition. This paper aims to present an approach for the categorization of depth oriented human action. In approach, enhanced motion static history images are computed set 2D auto-correlation gradient feature vectors obtained f...

This paper presents work on developing a software system for predicting crop yield from climate and plantation data. At the core of this system is a method for unsupervised partitioning of data for finding spatio-temporal patterns in climate data using kernel methods which offer strength to deal with complex data. For this purpose, a robust weighted kernel k-means algorithm incorporating spatia...

Neurocognitive model inspired by the putative processes in the brain has been applied to invention of novel words. This domain is proposed as the simplest way to understand creativity using experimental and computational means. Three factors are essential for creativity in this domain: knowledge of the statistical language properties, imagination constrained by this knowledge, and filtering of ...

We study correlations in the speckle patterns generated by scattering of perfect optical vortex (POV) beams and use them to produce a new class coherence functions, namely Bessel functions. Higher (zeroth) order functions have been realized cross (auto)-correlation between different orders. also studied propagation produced characterized their divergence with respect radius first ring for order...
