MOTIVATION Counting the number of occurrences of every k-mer (substring of length k) in a long string is a central subproblem in many applications, including genome assembly, error correction of sequencing reads, fast multiple sequence alignment and repeat detection. Recently, the deep sequence coverage generated by next-generation sequencing technologies has caused the amount of sequence to be...

The use of portable 2D echocardiography and ‘frame-based’ bubble counting as a tool to evaluate diving decompression stress. Diving and Hyperbaric Medicine. 2014 March;44(1):5-13.) Introduction: ‘Decompression stress’ is commonly evaluated by scoring circulating bubble numbers post dive using Dopple...

Camera based systems are routinely used for monitoring highway traffic, supplementing inductive loops and microwave sensors employed for counting purposes. These techniques achieve very good counting accuracy and are capable of discriminating trucks and cars. However, pedestrians and cyclists are mostly counted manually. In this paper, we describe a new camera based automatic system that utiliz...

introduction: due to the relation between structure and function of renal glomeruli, the study of glomeruli is very important to the understanding of initiation and progression of diabetic glomerulopathy. it seems that glomeruli disappear during the course of diabetic nephropathy without leaving recognizable corpuscles. this study was aimed to show diabetes mellitus effects on changes in renal ...

We show for a broad class of counting problems, correlation decay (strong spatial mixing) implies FPTAS on planar graphs. The framework for the counting problems considered by us is the Holant problems with arbitrary constant-size domain and symmetric constraint functions. We define a notion of regularity on the constraint functions, which covers a wide range of natural and important counting p...

We use production matrices to count several classes of geometric graphs. present novel for non-crossing partitions, connected graphs, and k -angulations, which provide another, simple elegant, way counting the number such objects. Counting graphs is then equivalent calculating powers a matrix. Applying technique Riordan Arrays these matrices, we establish new formulas numbers as well combinator...

Abstract Polar faculae are the footpoints of magnetic-field lines near Sun’s poles that seen as bright regions along edges granules. The time variation in number polar has been shown to correlate with strength magnetic field and be a predictor subsequent solar cycle. Due small size transient nature these features, combined different techniques observational factors, previous counts differ magni...

somatic embryogenesis is a new approache to plant mass in vitro propagation. this method influences by elements and their components in medium. in order to investigate the effects of different media and it,s role on somatic embryogenesis of carrot, a cbd experiment with four replications (including 12 treatments) was conducted. to do this, carrot petioles (with 1 cm dimension) in induction phas...
