With free-space optical communications in mind, researchers used a nanostructured birefringent metasurface to achieve a 16-fold increase in the corrected beam signal in mid-to-high-turbulence ...

Measuring how well blood flows to the brain is crucial for understanding a wide range of neurological issues, from strokes to migraines to traumatic brain injuries. Obtaining such measurements ...

Measuring blood flow in the brain is critical for responding to a range of neurological problems, including stroke, traumatic brain injury (TBI) and vascular dementia. But existing techniques, ...

Photonic crystals are periodic optical structures that can control the flow of light. Multiple reflections from surfaces separated by a distance similar to the wavelength prevent an optical beam from ...

Installing a smart water sensor can save you a lot of money and hassle. The best leak detectors we've tested immediately alert you to issues and even shut off your home's water supply. I’ve been ...

Oct. 25, 2025 — A UCLA-led team has achieved the sharpest-ever view of a distant star’s disk using a groundbreaking photonic lantern device on a single telescope—no multi-telescope array required.

Abstract: Analyzing plantar pressure trajectories is crucial for assessing foot behavior in dynamic gait stability. We propose the identification of foot symmetry and the detection of deformities by ...

Abstract: Estimating blood flow speed is essential in many medical and physiological applications, yet it is extremely challenging due to complex vascular structure and flow dynamics, particularly for ...
