We study the impact of service-time distributions on the distribution of the maximum queue length during a busy period for the M/G/1 queue. The maximum queue length is an important random variable to understand when designing the buffer size for finite buffer (M/G/1/n) systems. We show the somewhat surprising result that for three variations of the preemptive LCFS discipline, the maximum queue ...

apple scar skin viroid (assvd) is one of the most destructive viroid diseases in pome fruits orchards which can cause significant economic losses. symptoms of this viroid including scaring, distortion and dappling were seen in some apple orchards in east-northern of iran. sampling was carried out from apple and pear orchards. the rna was extracted by silica capture method from leaves. assvd was...

The crystal growth process by which fish antifreeze proteins (AFPs) and antifreeze glycoproteins (AFGPs) modify the ice morphology is analyzed in the AFP-ice system. A newly identified AFP-induced surface reconstruction mechanism enables one-dimensional helical and irregular globular ice binding surfaces to stabilize secondary, kinetically less stable ice surfaces with variable face indices. No...

This paper presents two methods for predicting the secondary structure of proteins based on artificial neural network learning. Two variations of NN learning rule are employed using feedforward backpropogation architecture for predicting secondary structure of proteins from their promary sequences of amino acids. About 500 sequences and more than 10000 patterns were trained with variable size o...

In this study we investigate the nature and distribution of an Intonation Phrase medial H tone in Tashlhiyt Berber. We analyse it as a right edge tone of an Accentual Phrase with a secondary association to a syllable with a sonorant nucleus. In the absence of such a syllable in the target word, H may align with a transitional vocoid, although its location is highly variable. Since these vocoids...

Presented herein is a closed-form mathematical solution for the construction of an orthogonal cross section of intersecting cylinder surface geometry created from a single planar section. The geometry in its 3-dimensional state consists of the intersection of two cylindrical surfaces of equal radii which is bounded on all four sides by planes orthogonal to the primary cylinder axis. A multivari...

Current population studies characterize idiopathic scoliosis as a single-gene disorder that follows the patterns of mendelian genetics, including variable penetrance and heterogeneity. The role of melatonin and calmodulin in the development of idiopathic scoliosis is likely secondary, with indirect effects on growth mechanisms. Reported abnormalities of connective tissue, skeletal muscle, plate...

FSGS is a histological description of the glomerular pathological findings; Clinically it is characterised by proteinuria, usually of nephrotic range, hypoalbuminaemia and variable degrees of renal impairment [1]. Sever nephrotic syndrome may increase the risk of thromboembolism [2]. FSGS is classified according to the aetiology into primary (idiopathic) and secondary. Secondary FSGS may be due...
