BACKGROUND Accidents that occur during dialysis treatment are notified to the medical staff via alarms raised by the dialysis apparatus. Similar to such real accidents, apparatus activation or accidents can be reproduced by simulating a treatment situation. An alarm that corresponds to such accidents can be utilized in the simulation model. OBJECTIVES The aim of this study was to create an ex...

Spence, QJE 1973 “Job Market Signaling” The big point: If there is a heterogeneity of types and there exists a signal which has a cost that is negatively correlated with productivity then there exist an infinite number of equlibirium which produce perfect information. Spence hopes to generate a model that “a considerable variety of market and quasimarket phenomena like admissions procedures, pr...

Our senses of hearing and balance rely on the function of specialized receptor neurons called "hair cells." In this issue of Neuron, Grant et al. report a series of elegant zebrafish experiments that reveal a previously unappreciated role for glia in the regulation of hair cell proliferation and differentiation. This work is a beautiful example of how zebrafish are particularly useful model sys...

BACKGROUND The methods of arrangement of combined intravenous parallel infusions using anti-reflux valve (ARV), with and without anti-syphon valve (ASV) that could decrease occlusion alarm delay were investigated. METHODS Occlusion challenge tests were mainly performed as bench experiments of four kinds of multiple parallel infusions (10 ml/h and 50 ml/h infusions), which were connected at th...
