Conservative Mastectomies provide removal of the entire breast parenchyma, saving the outer covering of the mammary gland with the possibility of performing an immediate reconstruction preserving women body image. With the oxymoron “conservative mastectomies”, we indicate Skin-Sparing Mastectomies (SSM), Nipple-Areola Complex-Sparing Mastectomies (NSM) and Skin-Reducing Mastectomies (SRM). Even...

tained by milk and nutrient enemata. On the 12th, he could open his mouth to a slight extent ; the symptoms were more favourable, and the spasms had diminished in force and frequency. On passing the flnger into the wound I detected a loose fragment of bone and removed it. The extremity of the lower fragment was sharp or pointed and this I cut off with the saw. From this date he gradually improv...

Recently, in [11], the “coin-turning walk” was introduced on Z. It is a non-Markovian process where steps form (possibly) time-inhomogeneous Markov chain. In this article, we follow up investigation by introducing analogous processes Zd,d≥2: at time n direction of “updated” with probability pn; otherwise next step repeats previous one. We study some fundamental properties these walks, such as t...

We study a novel multi-armed bandit problem that models the challenge faced by a company wishing to explore new strategies to maximize revenue whilst simultaneously maintaining their revenue above a fixed baseline, uniformly over time. While previous work addressed the problem under the weaker requirement of maintaining the revenue constraint only at a given fixed time in the future, the algori...
