Understanding a molecule that plays a key role in nitrogen fixing – a chemical process that enables life on Earth – has long ...

The numerical integration of stiff equations is a challenging problem that needs to be approached by specialized numerical methods. Exponential integrators form a popular class of such methods since ...

Abstract: Community detection is an important problem in unsupervised learning. This letter proposes to solve a projection matrix approximation problem with an additional entrywise bounded constraint.

The authors are social theorists who have long studied the roots and consequences of inequality. Aug. 15, 2025 In the early years of the 20th century, America had a “boy problem.” Boys on the street, ...

For the first time in its 95-year history, the Institute for Advanced Study (IAS) in Princeton, NJ, has appointed a woman as a permanent professor in its School of Mathematics. Last summer, computer ...

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, ...

ABSTRACT: The Einstein ring is usually explained in the framework of the gravitational lens. Conversely here we apply the framework of the expansion of a superbubble (SB) in order to explain the ...

Abstract: In this article, the optimal parking trajectory planning problem with chance constraints is considered. A conservative approximation-based method is presented to handle the chance ...
