Effect of Substitution Time on Physical, Technical and Cognitive Performance in Sub-Elite Male Field Hockey Players.

We examined the effects of substitution time (i.e., recovery time) in a simulated field hockey test on physical, technical and perceptual/cognitive performance.

Bayesian optimisation of restriction zones for bluetongue control.

We investigate the restriction of animal movements as a method to control the spread of bluetongue, an infectious disease of livestock that is becoming increasingly prevalent due to the onset of climate change. We derive control policies for the UK that minimise the number of infected farms during an outbreak using Bayesian optimisation and a simulation-based model of BT. Two cases are presented: first, where the region of introduction is randomly selected from England and Wales to find a generalised strategy.

Late failure of cochlear implantation resulting from advanced cochlear otosclerosis: surgical and programming challenges.

Objective: The objective of this study was to discuss cochlear implantation in the setting of severe cochlear otosclerosis and review programming challenges in a patient whose performance is deteriorating as a result of advancing disease.

Study Design: We conducted a case report and literature review.

Setting: Tertiary care medical center.

Off-pump multivessel coronary artery bypass utilizing the Octopus tissue stabilization system: initial experience in 374 patients from three separate centers.

Background: Renewed interest in coronary artery bypass without heart-lung support has lead to the development of specialized instrumentation to permit surgical exposure and grafting in all territories of the beating heart. This report summarizes the results of a multicenter, prospective trial using a single system of mechanical stabilization for multivessel revascularization without cardiopulmonary bypass.

Methods: Three principal investigators at different institutions performed off-pump coronary grafting utilizing the Medtronic Octopus suction stabilization system which provides a motionless region encompassing the target coronary artery.
