Metasurface Doppler Cloak for Broadband Radar Stealth
Advanced Physics Research, EarlyView.Suppressing the motion‐induced Doppler shift passes the target as part of the static clutter which is ignored by radars. Using a simple time‐modulation, frequency conversion is obtained from a metasurface‐based solution over a wide range. Referred to as a Doppler cloak, this work expands and validates such a varactor‐loaded prototype for broadband ...

Archaeological Prospection, EarlyView.ABSTRACT The emergence and development of settlement mounds, also called tells, is of major interest for the analysis of socio‐economic transformations occurring in the lower Danube plain during the East European Chalcolithic period. In this context, the multiphase chronology and structural layout of tells are highly relevant indicators, but small ...

Developmental Dynamics, EarlyView.Abstract Background Cell migration and invasion are well‐coordinated in development and disease but remain poorly understood. We previously showed that the neural crest (NC) cell migratory wavefront shares a 45‐gene panel with other cell invasion phenomena.

Microsaccades Tracking by Secondary Speckle Pattern Analysis
Journal of Biophotonics, EarlyView.A new approach for detecting microsaccades is introduced using secondary speckle patterns reflected from the sclera. This method offers potential benefits in capturing subtle eye movements and overcoming limitations in traditional pupil‐tracking systems.

Optimization of Iterative Control Algorithms for High-Resolution Adaptive Optics Systems
IEEE Photonics JournalAs the number of wavefront sensor subapertures and deformable mirror actuators in adaptive optics systems increases, the computational time of the direct gradient wavefront control algorithm is excessively long, which is a major factor affecting the ...
