This study was designed to determine the ability of computer-assisted sperm morphometry analysis (CASA-Morph) with fluorescence to discriminate between spermatozoa carrying different sex chromosomes from the nuclear morphometrics generated and different statistical procedures in the bovine species. The study was divided into two experiments. The first was to study the morphometric differences b...

Mechanical tension is an ever-present physiological stimulus essential for the development and homeostasis of locomotory, cardiovascular, respiratory, and urogenital systems. Tension sensing contributes to stem cell differentiation, immune cell recruitment, and tumorigenesis. Yet, how mechanical signals are transduced inside cells remains poorly understood. Here, we identify chaperone-assisted ...

The conventional assessment of human semen is a highly subjective assessment, with considerable intraand interlaboratory variability. Computer-Assisted Sperm Analysis (CASA) systems provide a rapid and automated assessment of the sperm characteristics, together with improved standardization and quality control. However, the outcome of CASA systems is sensitive to the method of experimentation. ...

casa (computer assisted semen analysis) systems are designed to assist andrologist labour. most available casa systems are not accurate or so expensive. therefore labours use manual methods to provide parameters. although some companies have achieved appropriate accuracy, they have not released their methods. so proposing methods in this area might be useful for groups who intend to design new ...

Twitter’s design allows the implementation of automated programs that can submit tweets, interact with others, and generate content based on algorithms. Scholars and end-users alike refer to these programs to as “Twitterbots.” This two-part study explores the differences in perceptions of communication quality between a human agent and a Twitterbot in the areas of cognitive elaboration, informa...

Exposure at the working place to various substances, that may affect semen quality is possible and should be investigated in detail. One appropriate method for this is computer-assisted sperm analysis (CASA) which offers multiple benefits in comparison to manual evaluation. However, several pitfalls exist, which make the evaluation of data obtained from CASA difficult to interpret. In the prese...

The lateral distribution of Cerenkov light at ground level records important information on the development of the air shower which produces it. We have constructed a Broad Lateral Non-imaging Cerenkov Array (BLANCA) to measure this lateral distribution at the CASA-MIA air shower detector in Dugway, Utah. Together, the arrays can sample the lateral distributions of electrons, muons, and Cerenko...
