This valuable study reports on a novel role of PD-1 in early T cell differentiation, showing that PD-1 stimulation impairs Th2 differentiation more effectively than that of Th1, with implications for ...

Wireless train-to-train communication is used to maintain a dynamically calculated, safe distance between the rail vehicles. This concept enables safe driving with relative braking distance as well as ...

Plant signalling involves the conveying of information within and between plant cells from receptor systems to effectors. Signals can take many forms, including chemical and electrical ...

Step-by-step exchanges are invariably associated with CAS systems. Hence, the signalling and traffic also follow the same path external to the node, i.e. on the transmission link. A3.3 Separation of ...

All of these technologies have in common the fact that they are single-ended, i.e. the signal is measured as a “high” or “low” level above ground. This is great for simple uses.

TOR (target of rapamycin) signalling is a cell signalling pathway. TOR and its mammalian ortholog mTOR are serine-threonine kinases that sense growth factor, nutrient or oxygen status and promote ...

Modern railway networks, including high-speed railways and urban mass rapid systems, rely on state-of-the-art signalling and communication systems to ensure safe and reliable operations. Railway ...

Small-signal amplifiers are needed to increase the tiny signal levels found at the input of a receiver into usable levels for the receiver s detector, or into the proper levels required of the final ...

A signal amplifier should only be used as a last resort when the television signal is weak. Even the best amplifier will still add some noise to the television signal it is amplifying/boosting ...

One closely-watched stock-market indicator is flashing a bright-red buy signal as more companies’ shares join the rally. A sharp increase in a measure known as the McClellan Summation Index is ...

Cellular signal boosters use big antennas to improve coverage in your home or car. These are the top signal boosters for apartments, houses, and vehicles. I’m one of PCMag’s mobile analysts.

MONTREAL — AtkinsRéalis Group Inc. says it has signed a deal with U.K. rail infrastructure owner Network Rail to help upgrade and digitize its signalling over the next 10 years. Network Rail ...
