Visual motion contains a wealth of information about self-motion as well as the three-dimensional structure of the environment. Therefore, it is of utmost importance for any organism with eyes. However, visual motion information is not explicitly represented at the photoreceptor level, but rather has to be computed by the nervous system from the changing retinal images as one of the first proce...

Molecular deletion screening with cDNA probes from the dystrophin gene was undertaken in patients with Becker muscular dystrophy from 58 separate families. Deletions were found in 41 (71%) of these families. Thirty-four (83%) of the deletions started in the same intron near the centre of the gene, and although there was no precise correlation between clinical severity and deletion pattern, the ...

INTRODUCTION It has been shown that B type natriuretic peptide (BNP) level can indicate cardiovascular disease. However, the association between BNP and metabolic risk factors is unknown. The aim of this study was to investigate the correlation between N-terminal pro-B type natriuretic peptide (NT-proBNP) and metabolic risk factors. MATERIAL AND METHODS A total of 11,508 subjects were selecte...

A controlled subjective test was carried out to assess selected spatial qualities of three virtual home theatre processors. The subjective results were used to evaluate a number of objective measurements based on the interaural cross-correlation coefficient (IACC). A novel implementation of the IACC was found which appears to correlate well with the subjective data.

According to the advantages of chaotic analog sequences and chaotic binary sequences, this paper proposes a method generating chaotic binary spread-spectrum sequence by multilevel quantifying. This paper proved that even correlation and odd correlation between such sequences of length N are all Gaussian distributed with mean 0 and variance N, the even of mean-square cross-correlation is N, and ...

background: for decades, it was suspected that diabetes contributed to poorer oral health and the increased frequency of periodontitis. more recently it was found that periodontitis could adversely affect glycemic control in diabetics. the aim of this study was to compare periodontal parameters with the metabolic sugar levels of diabetic and non-diabetic individuals. materials and methods: in t...

We describe the principles and practice of the study of higherorder correlation functions in suspensions of colloidal particles by intensity cross-correlation light scattering.
