Researchers have developed a new method for flexibly creating various needle-shaped laser beams. These long, narrow beams can be used to improve optical coherence tomography (OCT), a noninvasive and ...

Needle-shaped laser beams (NBs) featuring a long and narrow localization of photons can potentially allow non-diffracting pulses with undistorted temporal profiles. Using this kind of pulse in ...

In civil engineering, flexural beams are used to control the effect of vibrations that can cause cracks to appear in surfaces (concrete slabs) and beams. This is particularly important in buildings ...

When used in structural engineering, the term deflection refers to load-induced displacement, which typically affects beam designs. It can be an extremely complicated value to calculate when ...
