Cognition arises from the dynamic interaction of brain regions 1,2. Broad networks of regions are involved in sensory processing 3, decision making 4, and motor actions 5,6. Which network is engaged ...

In continuous-variable tomography, with finite data and limited computation resources, reconstruction of a quantum state of light is performed on a finite-dimensional subspace. In principle, the data ...

Aside from his work on the invariant subspace problem, Enflo solved two other major problems—the basis problem and the approximation problem—both of which had remained open for more than 40 years. By ...
