One of the features many-body quantum systems with Hilbert-space fragmentation is existence stationary states manifesting jamming. It was recently shown that these are "states memory", in which, e.g., measuring a localised observable has everlasting macroscopic effects. We study such measurement catastrophe an example stands out for its clarity. show particular at late times expectation value c...

industrial organizations are complex systems` where the interactions among the various functions such as sales, distribution, manufacturing, materials, finance, human resources and maintenance have to be man-aged towards a common purpose of delivering the customers satisfaction. however, since most of these or-ganizations have a `functional structure`, each function or department works towards ...

Background: One of the main causes of male infertility is the negative effects of oxidative stress. Follicle-stimulating hormone (FSH) plays an essential role in spermatogenesis, as well as in the maintenance of sperm DNA integrity. This study aimed to determine whether the recombinant human follicle-stimulating hormone (rhFSH) treatment of sperm parameters could positively affect sperm DNA and...

Background Heat shock protein A2 (HSPA2) is correlated with sperm maturity and function. Therefore, dysfunctional expression of this gene results in abnormal spermatogenesis. On the other hand, DNA damage in spermatozoa is considered to be an important cause of male infertility, and the presence of sperm with DNA fragmentation and chromatin abnormalities in human ejaculates is well documented, ...
