This paper provides a clusterhead review of clusterhead selection algorithm in Mobile Ad Hoc Networks (MANETs) and proposes a Stable Clusterhead Selection Algorithm for ad hoc networks (SCSA). The algorithm constructs a stable clusterhead with the help of reducing the number of clusterhead reconstruction. It selects the nodes which have the stability to be the clusterheaders. The results of sim...

Background: Sperm chromatin integrity assessment has been suggested as fertility predictor. The aim of this study was to examine the relationship between the results of sperm chromatin structure assay (SCSA) and the outcome of intrauterine insemination IUI. Materials and Methods: A total of 576 consecutive couples undergoing IUI were included and IUI was performed. SCSA results were expressed a...

Microscopic hyperspectral imaging technology is a potential non-destructive and non-contact method for colour measurement of micrometre-sized textile fibres. However, specularity on the fibre surface can distort accurate information affect accuracy measurement. This paper proposed specular-constrained sparse approximation (SCSA) specular-diffuse reflection separation from images wool First, spe...

INTRODUCTION Sperm chromatin integrity assessment has been suggested as a fertility predictor. The aim of this study was to examine the relationship between the results of sperm chromatin structure assay (SCSA) and the outcome of IVF, ICSI and intrauterine insemination (IUI). METHODS A total of 306 consecutive couples undergoing assisted reproduction were included. IUI was performed in 131, I...

The Long Term Evolution-Advanced (LTE-A) heterogeneous network (HetNet), which can increase the capacity of LTE-A, is composed of high power macrocells and low power picocells. However, unbalanced loading between macro and pico cells and inter-cell interference problems are two major performance bottlenecks in LTE-A heterogeneous networks (HetNets). We propose Self-Organizing Network (SON)-base...

Studies over the past two decades have clearly shown that reproductive toxicants cause sperm DNA fragmentation. This DNA fragmentation can usually be detected prior to observing alterations of metaphase chromosomes in embryos. Thus, Sperm Chromatin Structure Assay (SCSA)-detected DNA damage is viewed as the molecular precursor to later gross chromosome damage observed under the light microscope...

A neural network-based object detection algorithm has the advantages of high accuracy and end-to-end processing, it been widely used in synthetic aperture radar (SAR) ship detection. However, multi-scale variation targets, complex background near-shore scenes, dense arrangement some ships make difficult to improve accuracy. To solve above problem, this paper, a spatial cross-scale attention net...

Aim: To investigate the prevalence of high levels of sperm DNA damage among men from infertile couples with both normal and abnormal standard semen parameters. Methods: A total of 350 men from infertile couples were assessed. Standard semen analysis and sperm chromatin structure assay (SCSA) were carried out. Results: Ninety-seven men (28% of the whole study group) had a DNA fragmentation index...
