Machine learning techniques on homological persistence features for prostate cancer diagnosis.

The rapid evolution of image processing equipment and techniques ensures the development of novel picture analysis methodologies. One of the most powerful yet computationally possible algebraic techniques for measuring the topological characteristics of functions is persistent homology. It's an algebraic invariant that can capture topological details at different spatial resolutions.

Prevalence of and risk factors associated with cesarean section in Lebanon - A retrospective study based on a sample of 29,270 women.

Background: During the last decades, there has been an alarming and dramatic increase in the number of cesarean births in both developed and undeveloped countries. This increase has not been clinically justified but, nevertheless, has raised an important number of issues.
