Better predictions of how cracks grow can make machines and structures more reliable

Mathematical analysis and moving examples of the phase velocity of tones and signals. Generalization of phase velocity calculation.

Researchers have found a subtle signal that occurs two hours before major quakes, hinting that earthquake prediction is inching closer to possibility

Human depletion of groundwater has shifted the global distribution of water so much that the North Pole has drifted by more than four centimeters per year

A porous organic crystal readily and reversibly adsorbs water, with dehydration occurring well below the freezing point of water, which could be seen by a change in colour.

To build the DUNE neutrino experiment and its associated accelerator upgrade, experts invent customized ways to transport fragile, expensive and highly specialized components.

The Hassenstein-Reichardt detector is a bio-inspired algorithm for visual motion estimation that is based on the concept of spatiotemporal filtering. The algorithm takes as input a sequence of images and applies a spatiotemporal filter to each frame to detect motion in the scene.

High-Q mechanical resonances are desired in many applications. The conventional wisdom relies on minimizing the size of the supporting structure of mechanical resonators, which renders the fabricated mechanical device fragile.

Single-nanoparticle (NP) collisions have enabled the measurement of electrocatalytic reactions on single NPs by the nanoconfinement-amplified current. Recently, it has been demonstrated that the electrocatalytic activity of single NPs is improved by stochastic collision electrochemistry, because the good dispersion alleviates the aggregation, deactivation, and detachment of nano-electrocatalysts adhered on the…

"Maximum value in minimum time." Sounds good in theory, but traditional rubrics surreptitiously fail to produce the best answers, and fail to create explanations that help others understand why they're the best answers. This system works.

As electronic, thermoelectric and computer technologies have been miniaturized to nanometer scale, engineers have faced a challenge studying fundamental properties of the materials involved; in many cases, targets are too small to be observed with optical instruments.

Researchers have developed a scheme for AI-assisted design of fiber reinforced composite (FRC) structures with spatially varying optimal fiber sizes, making FRCs more lightweight without compromising their mechanical strength and stiffness.

A massive solar windstorm in 2017 compressed Jupiter's magnetosphere "like a giant squash ball," a new study reports.
