Standard Gaussian-type statistics are not really adequate to describe atmospheric variability; this traditional approach implicitly dismisses fluctuations as "noise" of use only in computing a standard deviation which, together with the mean, presumably varies so little in space and time that one can meaningfully speak of "climatological" values. In geophysics, unfortunately, this approach ofte...

The relationships between global, diffuse, and direct normal irradiance (GHI, DHI, and DNI respectively) have been the subject of numerous papers, and average correlations between the diffuse fraction and beam and the clearness index have been determined. This study examines the relationship by separating the cloudless periods and the cloudy periods. The relationship during cloudless skies is w...

During the last decade, selective photonic crystal filters have received much research interest in the fields of nanotechnology and optical interconnection network. The main focus of this paper consists of an analysis and a synthesis of one-dimensional photonic crystal selective filters. The optimization is performed by employing the simulated annealing algorithm. The filters synthesis is obtai...

The ABri and ADan amyloid peptides deposited in familial British and Danish neurodegenerative disorders are generated by processing mutant forms of the precursor protein BRI2. Although the pathogenic process that leads to deposition of amyloid in the brains of patients has been studied extensively, the cellular processes and normal function of the precursor protein did not receive much attentio...

BACKGROUND Mutations in the integral membrane protein 2B, also known as BRI(2), a type II trans-membrane domain protein cause two autosomal dominant neurodegenerative diseases, Familial British and Danish Dementia. In these conditions, accumulation of a C-terminal peptide (ABri and ADan) cleaved off from the mutated precursor protein by the pro-protein convertase furin, leads to amyloid deposit...
