Synchronization is achieved by triggering a 4 channel digital pulse generator (DG535, Stanford Research Systems, Inc., Sunnyvale, CA) with the output line of the GigE camera, which generates a 5V signal when the camera exposure is active.
In this scheme, each user can trigger a feedback only when the channel quality is greater than a pre-determined threshold.
Using Xenopus laevis neural crest, an embryonic stem cell population, as a model system, Blackiston et al. show that modulating the bioelectrical state of a population of 'instructor' cells expressing the native glycine receptor chloride channel can trigger a neoplastic phenotype in other cells, an effect that is mediated by long-range serotonergic signalling.
The interaction of particles with the cellular plasma membrane and its receptors and ion channels may directly trigger a biological response.
Within the logic unit, the rising edges of the input pulses are used to trigger an 8-ns pulse in channel A and a 4-ns pulse in channel B. The coincident time window is therefore 12 ns.
Base-level lowering of reservoirs impounding upstream sediment supply triggers a series of channel evolution steps such as degradation, lateral erosion, and redeposition that can dramatically alter the reservoir landscape and decouple the relationship between stream power and sediment supply.
where P n, i (T) is the estimated probability of successfully completing delivery of the media data unit n in discrete time interval T on channel i, NT is the target chunk delivery latency and t n, i * is the optimal waiting threshold (timeout in terms of intervals T) for receipt of the media chunk before triggering a switch to channel i.
Altogether, our results indicate that the STS/PKC412-induced Ca2+ influx by the HCN2 channel was sufficient to trigger an apoptotic response in NSCLC cells.
These findings suggest that in addition to the effects on β-catenin signalling, HAMLET triggers a Wnt-independent, ion channel-dependent mechanism controlling β-catenin in colon cancer cells.
