G-protein-coupled receptors are membrane proteins that are regulated by a small family of arrestin proteins. During formation of the arrestin–receptor complex, arrestin first interacts with the ...

When thinking about loops in programming languages, they often get simplified down to a conditions section and a body, but this belies the dizzying complexity that emerges when considering loop edge ...

Hi,<BR><BR>Long time ago when i wrote a simple program, i used a condition inside a while loop, that alowed me to exit the loop while it was runing, when i pressed the CTRL + Z or Q (not sure) comand.

In operational amplifier stability, one rule of thumb is to allow 45 degrees of phase margin. Other design guidelines state that 60 degrees is best; still others say that 30 degrees is sufficient.
