From quantitative spatial operator to qualitative spatial relation using Constructive Solid Geometry, logic rules and optimized 9-IM model: A semantic based approach

Abstract: The Constructive Solid Geometry (CSG) is a data model providing a set of binary Boolean operators such as Union, Difference and Intersection. In this work, these operators are used to ...

Twisting the Rules of Physics: Giant Magnetic Textures Emerge From Atomic Misalignment

A subtle twist between atomically thin magnetic layers can generate unexpectedly large and complex spin structures.

So Long, Ice Princesses. It’s the Blade Angels’ Time.

So said U.S. figure skater Alysa Liu, directly into a television camera, upon finishing her gold medal–winning routine in Milan on Thursday. The 20-year-old from Oakland, making a triumphant return ...

Why some tunes stick: Mathematical symmetry helps explain catchy melodies

Why do some melodies feel instantly right, balanced, memorable and satisfying, even if you have never heard them before? New research from the University of Waterloo suggests that more than creativity ...

AI system TongGeometry generates and solves olympiad-level geometry problems
