Adaptive LPD Radar Waveform Design with Generative Deep Learning [PDF]
We propose a learning-based method for adaptively generating low probability of detection (LPD) radar waveforms that blend into their operating environment. Our waveforms are designed to follow a distribution that is indistinguishable from the ambient radio frequency (RF) background -- while still being effective at ranging and sensing.

Silicon Nanowire Mats Enable Advanced Bioelectrical Recordings in Primary DRG Cell Cultures
Advanced Healthcare Materials, EarlyView.SiNW mat‐based MEA (NW_MEA) enables continuous intracellular recordings from neurons in primary rat DRG cell cultures, identifying C‐fiber nociceptors. Supported by an astrocyte feeder layer, SiNW mat promotes DRG neuron and glial cell growth, preserving in vivo‐like cell characteristics and allowing drug‐modulated activity monitoring.

The Generalized Sinusoidal Frequency Modulated Waveform for Active Sonar Systems [PDF]
arXiv, 2018 Pulse Compression (PC) active sonar waveforms provide a significant improvement in range resolution over single frequency sinusoidal waveforms also known as Continuous Wave (CW) waveforms. Since their inception in the 1940's, a wide variety of PC waveforms have been designed using either Frequency Modulation (FM), phase coding, or frequency hopping to ...
