There has been proposed a new approach to a neurocontrol synthesis under conditions of uncertainty. It does not directly use an optimization procedure. In terms of a synthesis technique, the proposed solution is close to inverse neurocontrol, but regarding its functions, the system has properties of a fast predictive control. There have been presented the(More)
BACKGROUND Necrotic arachnidism represents a common health problem and standard treatments are usually safe and effective. OBJECTIVE The aim of this study was to review documented Loxosceles species spider envenomations and identify the natural history of affected patients. METHODS A retrospective single-centre study included 52 patients with necrotic(More)
