Endometriosis: A Disease That Remains Enigmatic

Endometriosis, a gynecologic pathology, is defined by the presence of a tissue similar to uterine endometrium, which is located in places other than physiologically appropriate. These endometrial heterotopic islets contain glands and stroma and are functionally capable of responding to exogenous, endogenous, or local hormonal stimuli. Endometriosis affects 8%-10% of women of reproductive age; i...

2178 and All That

For integers g ≥ 3, k ≥ 2, call a number N a (g, k)-reverse multiple if the reversal of N in base g is equal to k times N . The numbers 1089 and 2178 are the two smallest (10, k)reverse multiples, their reversals being 9801 = 9 · 1089 and 8712 = 4 · 2178. In 1992, A. L. Young introduced certain trees in order to study the problem of finding all (g, k)-reverse multiples. By using modified versio...

On the Finite Groups that all Their Semi-Cayley Graphs are Quasi-Abelian

In this paper, we prove that every semi-Cayley graph over a group G is quasi-abelian if and only if G is abelian.
