By classifying workers as contractors, platform companies avoid paying core employment obligations while retaining tight ...

This quadratic programming problem can be seen as an extension to that of maximizing x/sup T/Ay (where y's components are also /spl plusmn/1). Grothendieck's inequality states that the ratio of the ...

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 ...

SINGAPORE – In poorer countries, where access to medical services is scarce, artificial intelligence (AI) tools can stand in as doctors in future. The Gates Foundation is one of the world’s ...
