Two studies fill in gaps about the cosmos’s ordinary matter. One maps it all, even the “missing matter.” The other details one of its hiding spots.

Gravity can exist without mass.” It’s a statement that upends a century of astrophysical dogma and, for some, sounds as ...

Particle swarm optimization (PSO) algorithms have exhibited good performance on well-known numerical test problems. In this paper, we propose a supervisor-student model in particle swarm optimization ...

A computational paradigm that can accurately simulate interactions between powerful laser beams and quantum fluctuations in a ...

Mobile and short-term monitoring campaigns are increasingly used to develop land-use regression (LUR) models for ultrafine particles (UFP) and black carbon (BC). It is not yet established whether LUR ...

Read our 2026 Tesla Model X review for information on ratings, pricing, specs, and features, and see how this SUV EV performed in our testing.

So, the high-energy particle wasn’t directly a dark matter particle, but rather a muon that decayed from dark matter likely fired from a blazar (a type of active galactic nucleus) right at Earth.

Kyle Hendricks stuck out nine and pitched six solid innings as the Los Angeles Angels earned their fourth straight win at Yankee Stadium with a 4-0 victory over the slumping New York Yankees Tuesday ...

Massive-Parallel Trajectory Calculations (MPTRAC) is a high-performance Lagrangian particle dispersion model designed to simulate and analyze atmospheric transport processes in the free troposphere ...

The Operational Policing Model (OPM), in place since 2019, has been an ‘unmitigated disaster and is not fit for purpose’, the Oireachtas Justice Committee will be told today. The OPM was introduced as ...

ggml moves fast, and can occasionally break compatibility with older file formats. rwkv.cpp will attempt it's best to explain why a model file can't be loaded and what next steps are available to the ...

A new variant of particle swarm optimization (PSO), named phase angle-encoded and quantum-behaved particle swarm optimization (θ-QPSO), is proposed. Six versions of θ-QPSO using different mappings are ...
