A family of new on-resonance saturation pulses for magnetization transfer in MRI is proposed. These pulses can be represented as a product of a shaped function and a cosine function. The shaped function can have many different forms, one of which is a Gaussian function. The experimental ...

a Frequency response of the tunable beam splitter measured using an on-chip detector up to the first resonance frequency normalized to the DC amplitude. The arrows represent the low bound of those measured amplitudes. Inset: this measurement was performed by translating the actuation voltage into a...
{xz}\)) strain components of the W-modes37and for any pair of the illustrated W- and S-modes the overlap integral is nonzero. The spectral matching is set by the external magnetic field. The highest interaction efficiency takes place at the resonance condition when the frequencies of the ...
In a laser-irradiated atomic cluster linear resonance absorption occurs when Mie-plasma frequency (ωM) matches the laser frequency (ω); and laser absorption is unconditionally presumed to be maximum here for the collisionless interaction. To judge it, we study interaction of short laser pulses of...
Step by step video & image solution for A series of pulses, each of amplitude 0.150 m, are sent on a string that is attached to a wall at one end. The pulses are reflected at the wall and travel back along the string without loss of amplitude. When two waves are present on the sam...

For example, although studies has shown single-pulse TMS stimulation of the right ventrolateral prefrontal cortex during concurrent functional magnetic resonance imaging inhibited amygdala activity in PTSD, greater ability of right dorsolateral, prefrontal, single-pulse TMS/functional magnetic resonance imaging...
It can be seen that the resonance vanishes in a at higher VJ, indicating that spin-orbit coupling and driving efficiency continue to decrease past the point at which coherent oscillations can be measured. Extended Data Fig. 6 Pulse sequences and additional data for coherence and switchability ...
