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 ... On this basis, we solve the weight hierarchies of a class of linear codes ...

When multilayer films are built up with polycations and polyanions, their thickness can grow either linearly or exponentially with the number of deposited layer pairs, depending for example on the ...

Abstract: 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 ...
