An eecient numerical solution scheme entitled adaptive diierential dynamic programming is developed in this paper for multiobjective optimal control problems with a general separable structure. For a multiobjective control problem with a general separable structure, the \optimal" weighting coeecients for various performance indices are time-varying as the system evolves along any noninferior tr...

The 5th edition of WHO Laboratory Manual for the Examination and Processing of Human Semen (2010) represents a comprehensive revision. This article aims to explore the applicability of this manual to andrology laboratories in China mainland in view of sperm count analysis, sperm motility analysis, sperm morphology analysis, sperm function analysis, anti-sperm antibody and seminal plasma biochem...

Sexual selection is the pervasive force underlying the dramatic divergence of sperm form and function. Although it has been demonstrated that testis gene expression evolves rapidly, exploration of the proteomic basis of sperm diversity is in its infancy. We have employed a whole-cell proteomics approach to characterize sperm divergence among closely related Mus species that experience different...

Abstract Reproductive success depends on efficient sperm movement driven by axonemal dynein-mediated microtubule sliding. Models predict sliding at the base of tail – centriole but such has never been observed. Centrioles are ancient organelles with a conserved architecture; their rigidity is thought to restrict Here, we show that, in mammalian sperm, atypical distal (DC) and its surrounding pe...

background: high level of semen reactive oxygen species is considered as an important factor in male infertility. sesame has antioxidant properties, which could be effective on improvement of semen parameters. this study was designed to determine the effects of sesame on sperm quality.   materials and methods: twenty‑five infertile men entered this clinical trial. they were treated with a 3â€...

introduction: the use of multiple cameras for motion analysis and single joint motion is very difficult and needs high technology in laboratory conditions. detection of single joint motion in kinesthesia and analysis of its changes can be done by one camera at one direction. in this study, we present the validity and reliability of a new prototype simulator system used for motion analysis appli...

The aim of this study was to map chromosomal regions containing hypothetical genes responsible for the following parameters of mouse semen quality: (1) the percentage of sperm with abnormal head morphology, (2) the level of dead spermatozoa, (3) the percentage of sperm tails with residual cytoplasmic droplets, and (4) the percentage of sperm with impaired sperm tail membrane integrity. We also ...

Laser trapping in the near infrared regime is a noninvasive and microfluidic-compatible biomedical tool. This chapter examines the use of optical trapping as a quantitative measure of sperm motility. The single point gradient trap is used to directly measure the swimming forces of sperm from several different species. These forces could provide useful information about the overall sperm motilit...

Identifying the code needed to perform software maintenance and evolution tasks can be very difficult and time consuming for large, complex software systems. A number of techniques have been proposed that employ either static or dynamic analysis to isolate code related to a feature of interest. Static approaches suffer from poor precision by including irrelevant code, while dynamic approaches c...
