Mixed guidance
n the nervous system, guidance molecules called semaphorins bind to receptors called plexins to induce motility and regulate axonal pathfinding. Now, Swiercz et al. (page 869) show that plexin-B1, after binding its ligand semaphorin 4D (Sema4D), forms a heterodimer with the tyrosine kinase ErbB2. This raises the intriguing possibility that the semaphorins and the EGF-like ligands of ErbB recept...

متن کاملOptimal Guidance of Pedestrian-Vehicle Mixed Flows in Urban Evacuation Network
In metropolitan areas, a potentially large number of pedestrians depend either on transit or other modes for evacuation, or need to walk a distance to access their passenger cars. In the process of approaching some designated pick-up points for evacuation, the massive number of pedestrians may incur tremendous burden to the vehicles on the roadway network. Thus, an effective coordination betwee...
متن کاملChallenges in implementing government-directed VTE guidance for medical patients: a mixed methods study
BACKGROUND Implementing venous thromboembolism (VTE) risk assessment guidance on admission to hospital has proved difficult worldwide. In 2010, VTE risk assessment in English hospitals was linked to financial sanctions. This study investigated possible barriers and facilitators for VTE risk assessment in medical patients and evaluated the impact of local and national initiatives. SETTING Acut...
متن کاملIntegrated fuzzy guidance law for high maneuvering targets based on proportional navigation guidance
An integrated fuzzy guidance (IFG) law for a surface to air homing missile is introduced. The introduced approach is a modification of the well-known proportional navigation guidance (PNG) law. The IFG law enables the missile to approach a high maneuvering target while trying to minimize control effort as well as miss-distance in a two-stage flight. In the first stage, while the missile is far ...
