In a review just published in Nature Materials, researchers take aim at the oldest principle in electronics: Ohm's law.

We restrict quadratic forms to subspaces of finite fields and obtain some interesting results about dual spaces. On this basis, we solve the weight hierarchies of a class of linear codes associated ...

A certain approximation scheme based on "piecewise linear" approximations of L 2 spaces is employed to formulate a numerical method for solving quadratic optimal control problems governed by linear ...
