Impact of Biomimetic Pinna Shape Variation on Clutter Echoes: A Machine Learning Approach
Advanced Intelligent Systems, EarlyView.Bats with dynamic ear structures navigate dense, echo‐rich environments, yet the echoes they receive are highly random. This study shows that machine learning can reliably detect structural signatures in these seemingly chaotic biosonar signals. The results open new directions for biologically inspired sensing, where time‐varying receiver shapes ...

Deep Learning Methods for Assessing Time‐Variant Nonlinear Signatures in Clutter Echoes
Advanced Intelligent Systems, EarlyView.Motion classification from biosonar echoes in clutter presents a fundamental challenge: extracting structured information from stochastic interference. Deep learning successfully discriminates object speed and direction from bat‐inspired signals, achieving 97% accuracy with frequency‐modulated calls but only 48% with constant‐frequency tones. This work

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Polyethylene glycol‐coated, lead‐free CsCu2I3 nanocrystal scintillator films achieve superior X‐ray imaging resolution over unpatterned films at 80 kVp by reducing crosstalk through lithographic micropatterning and optimized thickness control. The spatial resolution of X‐ray imaging is often limited by radioluminescence scattering, which is exacerbated
