Some marine bacterial species form mucosal layers, called veils, on sulfidic marine sediment. The bacteria attached to this veil actively swim and exert force on the surrounding fluid. The bacteria can break free of the veil and swim, chemotacting back to the veil. Over time the veil forms holes arranged in a hexagonal pattern. Motivated by this system, we present a simplified model to describe...

The behavior of collections of oceanic bacteria is controlled by metabolic (chemotaxis) and physical (fluid motion) processes. Some sulfur-oxidizing bacteria, such as Thiovulum majus, unite these two processes via a material interface produced by the bacteria and upon which the bacteria are transiently attached. This interface, termed a bacterial veil, is formed by exo-polymeric substances (EPS...

The veil of ignorance has been used often as a tool for recommending what justice requires with respect to the distribution of wealth. We complete Harsanyi’s model of the veil of ignorance by appending information permitting interpersonal comparability of welfare. We show that the veil-of-ignorance conception of John Harsanyi, so completed, and Ronald Dworkin’s, when modeled formally, recommend...

OBJECTIVE To systematically review previous studies and to evaluate the feasibility and safety of video endoscopic inguinal lymphadenectomy (VEIL) in vulvar cancer. METHODS We conducted a comprehensive review of studies published through September 2014 to retrieve all relevant articles. The PubMed, EMBASE, Web of Science, Cochrane Library, Wan Fang Data and Chinese National Knowledge Infrastr...

PURPOSE To report the surgical technique, procedural outcomes, and feasibility of simultaneous bilateral Video Endoscopic Inguinal Lymphadenectomy (VEIL) in the management of patients with indication for inguinal lymphadenectomy. SURGICAL TECHNIQUE VEIL was applied in all patients using the oncological landmarks (the adductor longus muscle medially, the sartorius muscle laterally and the ingu...

Computing targeted responses is a general problem in goal-directed behaviors. We sought the sensory template for directional turning in the predatory sea slug Pleurobranchaea californica, which calculates precise turn angles by averaging multiple stimulus sites on its chemotactile oral veil (Yafremava LS, Anthony CW, Lane L, Campbell JK, Gillette R. J Exp Biol 210: 561-569, 2007). Spiking respo...

INTRODUCTION Open inguinal lymphadenectomy is the gold standard for the treatment of inguinal metastasis in patients with penile cancer (PC). Recently the Video Endoscopic Inguinal Lymphadenectomy (VEIL) was proposed as an option to reduce the morbidity of the procedure in patients without palpable inguinal lymph nodes (PILN), however the oncological equivalency in patients with PILN remains po...
