Kavli Affiliate: Jonathan Rosner | Summary:Hadrons containing at least one heavy quark (charm or bottom) frequently have small enough natural widths that decay modes involving a single photon have detectable branching fractions. Photons of typical energy greater than 100 MeV have been directly detected, while those of lower energy have only been inferred. Here we […]

Kavli Affiliate: Mark Churchland | Authors: Sean M. Perkins, John P. Cunningham, Qi Wang and Mark M. Churchland | Summary: Decoders for brain-computer interfaces (BCIs) assume constraints on neural activity, chosen to reflect scientific beliefs while yielding tractable computations. We document how low tangling — a typical property of motor-cortex neural trajectories — yields unusual […]
