Gay and bisexual men continue to suffer the highest burden of HIV/AIDS in the U.S. Since the beginning of the epidemic, substance abuse has been shown to be one of the strongest predictors of sexual risk behaviors and seroconversion among this population.

This study compared self-reported experiences of sexual and physical abuse based on sexual orientation and gender in seven population-based surveys of youth. ...

We introduce the gonosomal algebra. Gonosomal algebra extend the evolution algebra of the bisexual population (EABP) defined by Ladra and Rozikov. We show that gonosomal algebras can represent algebraically a wide variety of sex determination systems observed in bisexual populations. We illustrate this by about twenty genetic examples, most of these examples cannot be represented by an EABP. We...
