Graphene holds promise for thin, ultralightweight, and high-performance nanoelectromechanical transducers. However, graphene-only devices are limited in size due to fatigue and fracture of suspended graphene membranes. Here, a lightweight, flexible,

Diagnostic ultrasound provides a means for estimating the spatial distribution of temperature in tissue in response to HIFU therapy. One approach to estimating the temperature is to distort backscattered ultrasound between two frames, one preceding a

Estimating the parameters of a pencil of lines is addressed. A statistical model for the measurements is developed, from which the Cramer Rao lower bound is determined. An estimator is derived, and its performance is simulated and compared to the bou

Phase propagation using the Rytov method has recently been proposed as a means for modeling the time‐of‐flight changes induced by thermal therapy [Speyer et al., J. Acoust. Am. 127]. These results are extended to measurements from a linear array,
