Stuck on a channel
Stuck on a channel ctive Ca 2 channels, according to Hudmon et al. (page 537), get their own dedicated Ca 2 sensors that cause well-used channels to open with gusto. Some Ca 2 channels, including voltage-gated L-type channels, let through more Ca 2 per opening when they are used frequently. This positive feedback, known as facilitation, allows fast-beating cardiac cells, for instance, to beat h...
متن کاملStuck in the divide
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 کاملStuck in the mud.
One had to be quick. Walk like a stork. Easier said than done, carrying a backpack full of equipment, buckets full of samples and a shovel over the shoulder, sinking knee-deep into the mud under the scorching tropical sun and watching out for crocodiles. I looked like a pig already. What was I doing here? Growing up near the coast of the North Sea, harbouring the Wadden Sea being one of the mos...
متن کاملStuck-Free Conformance
We present a novel refinement relation (stuck-free conformance) for CCS processes, which satisfies the substitutability property: If I conforms to S, and P is any environment such that P | S is stuckfree, then P | I is stuck-free. Stuck-freedom is related to the CSP notion of deadlock, but it is more discriminative by taking orphan messages in asynchronous systems into account. We prove that co...
متن کاملCrowd dynamics - being stuck
In physics, a phase transition from liquid to solid means that molecules are stuck between their neighbours. We investigate a similar effect in a crowd at a small exit. People cross the exit one by one, but the majority moves very slowly. Those from behind press, and if the density is large enough, it is impossible to move with respect to our neighbours. Can one withdraw from the crowd or he/sh...
