Rubidium vapor cells play a key role in contemporary quantum optics since they have strong nonlinear interactions with low-power incident laser light. The simplest nonlinear interaction is the Kerr effect. Although most calculations concentrate on the unsaturated Kerr effect, the saturated Kerr effect has been measured in many material including 85Rb and 87Rb vapor.

Genetic underpinnings of predicted changes in cardiovascular function using self supervised learning

AbstractBackgroundThe genetic underpinnings of cardiovascular disease remain elusive. Contrastive learning algorithms have recently shown cutting-edge performance in extracting representations from electrocardiogram (ECG) signals that characterize cross-temporal cardiovascular state. However, there is currently no connection between these representations and genetics.

When an optical beam passes through a thin slice of a homogeneous material, the change of its phase and amplitude is characterized by its linear and nonlinear susceptibility, the latter also known as the hyperpolarizability. The standard method for measuring the nonlinear susceptibility is the $Z$-scan. This widely-used method is sometimes applied outside of its range of validity, leading to systematic errors.

Very late to this but it’s timeless and I highly recommend. Great sports-heavy nostalgia and commentary.

It’s weird that NBA refs announce reviews by name and not number, but it leaves open the possibility that one of them might announce the player by his NBA twitter slander nickname.
