A new mathematical model of a wormhole suggests that two black holes can be “cut and pasted.” Cut and paste is an official concept in math, referring to two surfaces that may be transposable. In this ...

Abstract: We propose a community detection method based on K-shell. Our method determines some core nodes of the graph according to the K-shell value of these nodes. These core nodes constitute a ...

A new study by Shanghai Jiao Tong University and SII Generative AI Research Lab (GAIR) shows that training large language models (LLMs) for complex, autonomous tasks does not require massive datasets.

Robots often move inefficiently due to slow mathematical computations. Now, a new method called Web of Affine Spaces (WASP) Optimization, developed by Yale’s Professor Danny Rakita and his team, ...

Disjoint convex shell (DC-shell) is a set of disjoint convex objects approximating non-convex overlapping object sets. The DC-shell method we proposed provides better approximation than those created ...

The geography of the Pacific presents a different problem set than the primary threat faced in Europe, demanding different weapon capability requirements. The framework that underpinned conventional ...

A key fault line in contemporary education is between those who see public schools as foundational to democracy and those who regard them as ineffectual and captive to union interests. In his new book ...

Abstract: Bearing shells are widely used in heavy-load friction pairs of high-end machines to reduce wear, thereby extending the lifetime of machines. Tribotests are necessary for bearing shells to ...
