We embed a directed graph G(V, E) in a representation of a naval minefield; vertices V represent waypoints and edges E denote possible segments for ship transit. A new model identifies a simple s‐t path through the minefield that minimizes the risk of incurring unacceptable damage from threats, that is, mine detonations. Traditional “edge‐additive” models rely on shortest‐path algorithms that over‐accumulate...
Conventional laparoscopic nephrectomy (LN) is the gold standard approach for nephrectomy. An advance in minimally invasive nephrectomy is laparoendoscopic single-site nephrectomy (LESS-N).To compare 5-yr experience and outcomes of LESS-N to LN.Retrospective, case-control, single-surgeon series of 47 LESS-N cases matched in a 1:2 fashion by age, indication, and tumor size to 94 LN controls. LESS-N...
