Advanced Intelligent Systems, EarlyView.A piezoelectric meta‐transducer generates an ultrasonic rainbow, steering guided elastic waves to different angles according to frequency. A dithering‐based binary electrode design enables a closer realization of the target wavenumber filter, improving directional purity and suppressing unwanted lobes. Numerical and experimental validation demonstrates

The Doppler-Delay Characteristic of the Aeronautical Scatter Channel
, 2011 The objective of this paper is to characterize the scattered components in an aeronautical channel in terms of delay and Doppler frequency. Geometric considerations make it possible to locate the scatterers on the ground and derive analytical ...

A causal model for linear RF systems developed from frequency-domain measured data [PDF]
, 2005 With the ever-growing complexity of interconnect networks, models developed from measured data or data from 3-D electromagnetic simulators are increasingly becoming essential. It is to this end that the current contribution is directed. In particular, it

Clinical Advances in Periodontics, EarlyView.Abstract Background Effective flap management is crucial for successful bone regeneration procedures. Traditional flap release has been performed by the deep split design; recently, the superficial split design revives for its proposed anatomical and biomechanical advantages.

Unified Framework and Comparative Analysis of Delay-Doppler Communication Systems
IEEE Open Journal of the Communications SocietyDelay-Doppler (DD) system translates a time-varying channel into quasi-static time invariant channel by modulating the information in DD domain. This serves as a core principle behind orthogonal time frequency space (OTFS) and orthogonal delay Doppler ...

Cardiac remodeling and arrhythmia in a mouse model of Depdc5 haploinsufficiency
Epilepsia, EarlyView.Abstract Objective Some ion channel genes linked to developmental and epileptic encephalopathy (DEE) are also linked to cardiac arrhythmia, leading to the hypothesis that predisposition to cardiac arrhythmias may contribute to the complex disease presentation of DEE and possibly to the mechanism of sudden unexpected death in epilepsy.

Radar Sensing via OTFS Signaling: A Delay Doppler Signal Processing Perspective
, 2023 The recently proposed orthogonal time frequency space (OTFS) modulation multiplexes data symbols in the delay-Doppler (DD) domain. Since the range and velocity, which can be derived from the delay and Doppler shifts, are the parameters of interest for ...
