Conventionally, in order to acoustically match thickness mode piezoelectric transducers to a low acoustic impedance load medium, multiple quarter wavelength (QW) matching layers are employed at the ...

Artificial structures known as phononic crystals and acoustic metamaterials can be designed by spatially arranging one or more materials to obtain desired wave manipulation characteristics. The ...

Impedance mismatch due to bridge taps is a data rate limiting factor in DSL systems including VDSL. Three impedance matching approaches are investigated for VDSL transmission through twisted-pair ...

Nanodroplets have emerged as promising contrast agents due to their ability to undergo acoustic droplet vaporization (ADV), enabling size expansion for diverse biological applications such as ...

Impedance matching is one of the perpetual confusions for new electronics students, and for good reason: the idea that increasing the impedance of a circuit can lead to more power transmission is ...

Acoustic and optical traps enable contactless manipulation of objects, but trapping has been limited to homogeneous environments. Wavefront shaping now extends this versatile manipulation tool to ...

A former Dodgers fan favorite called the 2024 World Series a complete mismatch.

Learnerships represent a powerful antidote to the skills mismatch plaguing our economy. These programmes combine theoretical learning with practical workplace experience, creating a bridge between ...

Kelly didn't pitch in the postseason after being sidelined by injury, but that didn't stop him from explaining why he believes the 2024 World Series between the Dodgers and New York Yankees was a ...

Electrochemical aptamer-based (EAB) sensors are capable of measuring the concentrations of specific molecules in vivo, in real time, and with a few-second time resolution. For their signal ...
