Analog computers are systems that perform computations by manipulating physical quantities such as electrical current, that map math variables, instead of representing information using abstraction ...

Analogue computers that rapidly solve a key type of equation used in training artificial intelligence models could offer a potential solution to the growing energy consumption in data centres caused ...

Abstract: To deal with time-varying equations, a novel recurrent neural network, named varying-parameter convergent-differential neural network (in short, VP-CDNN ...

A seemingly simple math problem has gone viral this week, leaving people totally stumped on social media. The equation in questions is: 15 - 15 × 4 ÷ 2 = ? At first glance, it looks like a basic grade ...

The brainteaser, which has gone viral on X (formerly Twitter), appears to show four basic equations. At first glance, the equation seemingly shows a pattern, one that is not easily cracked. Can you ...

M-M.E.S.S. provides low-rank solvers for large-scale symmetric matrix equations with sparse or sparse + low-rank coefficients. The main focus is on differential and algebraic Riccati equations ...

We study the solvability of the equation AX + XA * = XA + A * X = I. In particular, we obtain various criteria for the normality of A in terms of Hermitian solutions of the equation which satisfy ...

A new mathematical brainteaser has been dubbed "frustrating" after it left even the brightest minds stumped. Shared by the account @BrainyBitsHub on X (formerly Twitter), this new puzzle has left ...

Calculation: A representation of a network of electromagnetic waveguides (left) being used to solve Dirichlet boundary value problems. The coloured diagrams at right represent the normalized ...

Presenting an algorithm that solves linear systems with sparse coefficient matrices asymptotically faster than matrix multiplication for any ω > 2. Our algorithm can be viewed as an efficient, ...
