Physicists from Adolfo Ibáñez University and Columbia University have identified stable, 'frozen-in' gravitational structures that remain preserved as spacetime evolves. Using analogies from fluid ...

The concept of spacetime, first described in Einstein's theory of general relativity, has since been widely studied by many ...

In the increasingly digital world, the demand for faster, more efficient and miniaturized optical devices is ever-growing.

It’s the same math that explains how, under the right conditions, the atmosphere above a barren plain can produce a roiling tornado. Merle has had enormous success taming these blowups in the ...

Abstract: Novel nonlinear functions are introduced to construct first-order nonlinear filters to address the following critical issues encountered in widely used dynamic surface control (DSC) methods.

Researchers at the University of California, Los Angeles (UCLA) have developed an optical computing framework that performs large-scale nonlinear computations using linear materials. Reported in ...

NTT Research, Inc., a division of NTT, announced that its Physics and Informatics (PHI) Lab, working with Cornell University and Stanford University, has developed the world's first programmable ...

Abstract: This letter proposes a novel complex-valued nonlinear function (CVNF) approximation method for adaptive nonlinear filter, which is used to digitally cancel the weak nonlinearity, a commonly ...
