In the early 1980s, researchers at NASA's Jet Propulsion Laboratory in California realized that stable reference signals generated by a hydrogen maser atomic clock could be distributed over optical ...
The phase determines the oscillation frequency, and gain is a criterion for oscillation to exist. The four poles in the loop equation each contribute –45° phase shift accumulating the required total ...
Aggarwal et al. develop OCaMP, an orange fluorescent calcium indicator optimised for imaging neural activity at wavelengths above 1000 nm, enabling improved deep tissue imaging and expanded ...
