How Modes Shape Casimir Physics
Modes have steadily influenced the understanding of physical systems through time. At least since the prediction of the Casimir effect, they also play a very important role in Casimir physics and in the understanding of the different phenomena typical of this research field.

As much as there has been a significant increase in the development of railway systems in recent years, one of the significant drawbacks on this mode of transport is ground-borne vibrations and noise emanating from vehicle-track interaction in service ...

Dynamic Characterization of Cercal Mechanosensory Hairs of Crickets
Previous dynamic characterizations of the cercal mechanosensory hairs of crickets have generally been limited to the first resonant frequency and associated deflection shape.

SCALING OF OPERATIONAL MODE SHAPES USING SENSITIVITY ANALYSIS [PDF]
Recently, identification of dynamic properties of structures such as bridges, towers and building, which are not easy to excite, is possible by measuring only the output responses. Due to measuring only the responses when the structure is excited only by

Microbubble shape oscillations excited through ultrasonic parametric driving\ud [PDF]
An air bubble driven by ultrasound can become shape-unstable through a parametric instability. We report time-resolved optical observations of shape oscillations (mode n=2 to 6) of micron-sized single air bubbles.

Mode conversion via wavefront shaping
In recent years, wavefront shaping has been utilized to control and correct distorted light for enhancing a bright spot, generation of a Bessel beam or darkening a complete area at the output of a scattering system. All these outcomes can be thought of as enhancing a particular mode of the output field. In this letter, we study the relation between the

Control of lasing in fully chaotic open microcavities by tailoring the shape factor [PDF]
We demonstrate experimentally that lasing in a semiconductor microstadium can be optimized by controlling its shape. Under spatially uniform optical pumping, the first lasing mode in a GaAs microstadium with large major-to-minor-axis ratio usually ...

Effect of Pulse Shaping on Subharmonic Aided Pressure Estimation In Vitro and In Vivo. [PDF]
OBJECTIVES: Subharmonic imaging (SHI) is a technique that uses the nonlinear oscillations of microbubbles when exposed to ultrasound at high pressures transmitting at the fundamental frequency ie, f METHODS: Eight waveforms with different envelopes were ...
