A Gaussian beam is transformed into a Bessel beam using a binary axicon and then reshaped by a flat multilevel diffractive lens into a micron-sized optical bottle beam, enabling long-distance ...

Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long ...

DAYTONA BEACH, Fla. — NASCAR today revealed the 2026 NASCAR Whelen Modified Tour schedule, a 16-race slate that blends tradition, competition and fan-favorite venues. “Regional racing has always been ...

Bessel functions, central to many problems in mathematical physics, provide solutions to differential equations that describe wave propagation, heat conduction and vibrations in cylindrical or ...

Abstract: Modified Bessel functions of the second kind are widely used in physics, engineering, spatial statistics, and machine learning. Since contemporary scientific applications, including machine ...

Function Health said it acquired full-body MRI scanning company Ezra. Function offers a $499 annual subscription where members complete more than 160 blood tests and track their results over time.

As a person with a chronic illness, I'm no stranger to bloodwork. I used to pore over my lab results, googling the various meanings, and trying not to panic when a test fell out of range. Function ...

ABSTRACT: The properties of Cylindrical Internal-Surface Acoustic Waves (CISAW) propagating on the inside surface of a high purity fused quartz tubular fiber are derived from basic principles using a ...

On Oct. 26, NASCAR announced an extension of the entitlement partnership for its original division; Whelen Engineering returns to the Modified Tour through 2029. In conjunction with that announcement, ...
