Abstract: Permutation entropy (PE) is a widely used metric for quantifying the complexity of time series data. Recent efforts have extended PE to graph signals, resulting in the graph permutation ...

Abstract: Real-time motion planning in dynamic environments presents a significant challenge for robotic manipulators. This article introduces an innovative parallel model predictive path integral ...

CEO Sam Altman called a strange graph in its GPT-5 presentation a ‘mega chart screwup.’ CEO Sam Altman called a strange graph in its GPT-5 presentation a ‘mega chart screwup.’ is a senior reporter ...

For the first time, physicists have directly measured the temperature of extremely hot gold particles using a giant X-ray laser—a breakthrough with major implications for engineering spacecraft or ...

Just about anybody who played hide-and-seek as a kid remembers counting, with eyes (presumably) covered, in units of one-one-thousand. “One-one-thousand. Two-one-thousand. Three-one-thousand.” It’s ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

A physicist proposes that time has three dimensions instead of one, which could finally unite quantum mechanics and Einstein’s relativity into a single theory. The theory makes specific, testable ...

BingoCGN employs cross-partition message quantization to summarize inter-partition message flow, which eliminates the need for irregular off-chip memory access and utilizes a fine-grained structured ...

Three-dimensional time is a theory in which time, like space, has multiple independent directions — typically imagined as three axes of time motion, similar in concept to the spatial X, Y and Z axes.
