A dance of galaxies: JWST captures interacting dwarf galaxies

NASA's James Webb Space Telescope captured two nearby dwarf galaxies interacting with each other in this image released on ...

NAC protein complex slows early synthesis to optimize cellular protein production

Proteins are among the most important molecular building blocks of life. They are chains of amino acids assembled in our cells by ribosomes, the molecular "protein factories" of our bodies. The ...

Interval Methods for Multi-Point Collisions between Time-Dependent Curved Surfaces

We present an efficient and robust algorithm for finding points of collision between time-dependent parametric and implicit surfaces. The algorithm detects simultaneous collisions at multiple points ...

Enhancing Collision-Free Formation Control in Multiagent Systems: An Approach Based on Time-Derivative of Artificial Potential Functions

Abstract: The artificial potential function (APF) is a widely applied algorithm in collision-free formation control in multiagent systems (MASs). However, it suffers from oscillations and acceleration ...

Optimization-Free Smooth Control Barrier Function for Polygonal Collision Avoidance

Abstract: Polygonal collision avoidance (PCA) is short for the problem of collision avoidance between two polygons (i.e., polytopes in planar) that own their dynamic equations. This problem suffers ...
