A normal ECG has three key parts -- a P wave, a QRS complex, and a T wave -- and together they tell us how the heart's electrical system is functioning. This little P wave is where it all starts.

Careful measurement of all intervals between intrinsic QRS complexes to stimulus indicated ... at the ascending portion of the repolarization wave (Fig. 3). A check of the output characteristics ...

D-Wave's quantum computer reportedly performed a quantum simulation faster than classical computers, simulating quantum dynamics of spin glasses to describe magnetic materials.

Canadian quantum computing company D-Wave has solved complex scientific simulations that classical supercomputers could not resolve using its 'quantum annealing' processor. Quantum supremacy ...
