Neutrophils have been implicated in the pathogenesis of the adult respiratory distress syndrome (ARDS). We have measured concentrations of the neutrophil attractant interleukin-8 in blood and bronchoalveolar lavage fluid (BAL) from patients at risk of ARDS. We studied 29 patients from three groups at risk of developing ARDS: multiple trauma (n = 16),(More)
Deciding what to include in a model is the essence of physical modeling. If this kind of decisions is done incorrectly, it results in a model that is both less accurate and offers less performance than others. This paper presents a method to deal with these decision problems and quantify the results. A workflow is proposed, where the modeler first builds a(More)
In this paper, we investigate the load balancing effect of stochastic routing in wireless sensor networks. Our motivation is based on the common claim that the randomness in routing achieves energy-efficient load balancing. We introduce an evaluation framework based on discrete time absorbing Markov chains for destination-based stochastic routing. Based on(More)
A 64 year old woman was brought by ambulance to the accident and emergency department. She had been referred by her GP because of increasing dyspnoea, cyanosis, and lethargy over the previous four days. On arrival of the ambulance crew at her home she was noted to be tachycardic and tachypnoeic (respiratory rate 36/min) with a GCS of 5 (E 3, M 1, V 1). She(More)
