Analog computers are systems that perform computations by manipulating physical quantities such as electrical current, that ...

Chinese researchers develop high-precision scalable analog matrix computing chip based on resistive memory, realizing for the first time an analog computing system whose accuracy rivals that of ...

Combination of real and imaginary parts (CRI) works well for solving complex symmetric linear systems. This paper develops a generalization of CRI method to determine the solution of Sylvester matrix ...

The question of whether we live in a real world or a simulated one has plagued philosophers for centuries - but now scientists believe they finally have found a way to test the theory. By Lucy Kinder ...
