Ultimately, the purpose of the review was to explain the physics behind the bioeffects that can occur when a US beam interacts with tissues so that practitioners of POCUS would have some knowledge of the issues involved, and there's no doubt that the physics is complex. The most basic ...

Finally, this two-photon N00N state was focused down to a 25 μm Gaussian beam waist radius and coupled into a SMF (with a mode field diameter of 5 μm) that was scanned through the focus (from behind the focus towards the lens). The two-photons were then probabilistically split...
ultrasound-assisted bioprinting (UAB) that utilizes acoustophoresis principle to align cells within bioprinted constructs. We describe the underlying process physics and develop and validate computational models to determine the effects of ultrasound process parameters (excitation mode, excitation time, ...
The use of ultrasound is now commonplace in medicine and elsewhere but demonstrating how it works is not easy. The suggestion here is to use coaxial cables of different impedance to model the different Specific Acoustic Impedances of parts of the body. DOI: 10.1088/0031-9120/33/6/018 年份...
