BACKGROUND AND OBJECTIVES In this single-institution study, we aimed to compare the safety, feasibility, and outcomes of single-incision laparoscopic sigmoidectomy (SILSS) with multiport laparoscopic sigmoidectomy (MLS) for recurrent diverticulitis. METHODS Between October 2011 and February 2013, 60 sigmoidectomies were performed by the same surgeon. Forty patients had a MLS and 20 patients h...

The celebrated multi-armed bandit (MAB) problem, originating from the work of Gittins et al. [GGW89], presumes a condition on the arms called the martingale assumption. Recently, A. Gupta et al. obtained an LP-based 1 48 -approximation for the problem with the martingale assumption removed [GKMR11]. We improve the algorithm to a 4 27 -approximation, with simpler analysis. Our algorithm also gen...

Acute kidney injury (AKI) is a serious medical condition affecting millions of people. Patients in intensive care unit (ICU) who develop AKI have increased morbidity and mortality, prolonged length of stay in ICU and hospital and increased costs, especially when they require renal replacement therapy. In the latter case, morbidity and mortality increase further. In order to meet the needs of th...

We provide a non-interleaving operational semantics for the pi-calculus as asynchronous transition systems, which generalizes the standard interleaving structural operational semantics and unfolds to standard, stable prime event structures. We follow the approach taken by Mukund and Nielsen in providing non-interleaving semantics for CCS by infering the so-called prefixing (structural or subjec...
