This tried-and-true method is one of the best ways to study so you actually retain information—and it's not hard to do. Here's what you need to know.

Abstract: Estimating low-rank positive-semidefinite (PSD) matrices from symmetric rank-one measurements is of great importance in many applications, such as high-dimensional data processing, quantum ...

Abstract: An iterative algorithm to solve periodic Riccati differential equations (PRDE) with an indefinite quadratic term is proposed. In our algorithm, we replace the problem of solving a PRDE with ...

They would be the Big Apple’s cat crusaders. Mayoral hopeful Curtis Sliwa is pitching a plan to solve New York City’s rat problem — unleashing a strike team of feral cats to hunt down the rodents at ...
