Stopping traffic.
Nitric oxide (NO) is an important mediator of host defence and of vascular tone. In septic shock, upregulation of inducible NO synthase leads to the production of vast amounts of NO, which contribute to pathogen elimination but also to inappropriate vaso-dilation and to loss of vascular resistance. Asymmetric dimethyl-arginine (ADMA) is an endogenous inhibitor of NO synthases shown to contribut...
متن کاملStopping Unwanted Traffic using Lightweight Permits ⋆
One of key security issues on the current Internet is unwanted traffic, the forerunner of unauthorized accesses, intrusions, Denial of Service (DoS) attacks, port scanning, and other attacks. Since stopping unwanted traffic is vitally important but extremely challenging, we need a series of defensive schemes to identify unwanted packets, filter them out, and further defeat their associated atta...
متن کاملNon Stopping times and Stopping Theorems
Given a random time, we give some characterizations of the set of martingales for which the stopping theorems still hold. We also investigate how the stopping theorems are modified when we consider arbitrary random times. To this end, we introduce some families of martingales with remarkable properties.

متن کاملMoving or Stopping Mitochondria: Miro as a Traffic Cop by Sensing Calcium
Mitochondrial transport in neurons and their spatial distribution among synapses are directly correlated with synaptic activity. One paper in this issue of Neuron (MacAskill et al.) and two papers recently published in Cell (Wang and Schwarz) and PNAS (Saotome et al.) provide compelling evidence that Miro serves as a calcium sensor that controls mitochondrial mobility.
متن کاملOptional Stopping
Introduction Suppose you are determined to “prove” that green apples cause cancer. An Optional Stopping strategy (OS) is where you keep looking sampling experimental data until the observed correlation between eating green applies and cancer is significantly different from 0 (where “significantly” means that the null hypothesis is rejected by standard statistical tests). That is, you follow a r...
