A deep learning approach to photo–identification demonstrates high performance on two dozen cetacean species

Methods in Ecology and Evolution, 2023
Researchers can investigate many aspects of animal ecology through noninvasive photo–identification. Photo–identification is becoming more efficient as matching individuals between photos is increasingly automated.

A 32-mV Supply Ring Oscillator Composed of Modified Schmitt Trigger Delay Cells for Integrated Start-Up Circuits in DC Energy Harvesting Systems

IEEE Access
Implementing fully integrated start-up energy harvesting (EH) systems is very challenging. The most popular start-up circuit implementations use a low-voltage ring oscillator (RO).

A Large‐Area Broadband Multimodal Dual‐Resonant Haptic Device for Bidirectional Telerobotic and Augmented Interactions

Advanced Science, EarlyView.
We present a large‐area bidirectional human–machine interface integrating electrostatic multimodal tactile sensing with a dual‐resonant haptic actuator. The system enables linear pressure sensing that is decoupled from actuation and stable broadband vibrotactile feedback under dynamic contact conditions, supporting real‐time feedback modulation aligned
