Aims. To understand the nature of γ−ray loud active galactic nuclei (AGN) and the mechanisms for the generation of high-energy γ−rays. Methods. We performed a homogeneous and systematic analysis of simultaneous X-ray and optical/UV properties of a group of 15 γ−ray loud AGN, using observations performed with XMM-Newton. The sample is composed of 13 blazars (6 BL Lac and 7 Flat-Spectrum Radio Qu...
We provide a new lower bound on the number of (≤ k)-edges of a set of n points in the plane in general position. We show that for 0 ≤ k ≤ bn−2 2 c the number of (≤ k)-edges is at least Ek(S) ≥ 3 ( k + 2 2 ) + k ∑ j=b3 c (3j − n + 3), which, for b3 c ≤ k ≤ 0.4864n, improves the previous best lower bound in [11]. As a main consequence, we obtain a new lower bound on the rectilinear crossing numbe...
Abstract Introduction Genital tucking is a practice performed by some transgender women and gender nonconforming individuals to reduce or conceal the contour of penis testicles. A variety genital techniques exist that are used achieve an individual’s desired appearance. The scrotum may be moved into perineal area between buttocks.
