$V_{ub}$ is the smallest and least known of all CKM matrix elements; it's currently determined primarily through the exclusive process B → π l 𝜈. I will present progress toward a lattice QCD determination of the $V_{ub}$​ matrix element from a novel transition -- the B → π … Read More

Islets of Langerhans consist of a large functional syncytium of beta cells that produce pulses of insulin, a key component for controlling metabolic homeostasis. In response to stimulation, the islet cells display rather well-coordinated intercellular activity patterns, which was found … Read More
