Neuromorphic Photonic Processing and Memory With Spiking Resonant Tunneling Diode Neurons and Neural Networks

Advanced Intelligent Systems, EarlyView.
This work shows resonant tunneling diode‐based opto‐electronic spiking neurons enabling fast edge detection in time series, a two‐layer photonic spiking neural network for complex classification, and a depth‐tunable photonic spiking memory system. Neuromorphic computing—modeled after the functionality and efficiency of biological neural systems—offers ...

Rangewide responses of Mimulus cardinalis to an extreme heat event

American Journal of Botany, EarlyView.
Abstract Premise Extreme events are an understudied aspect of ongoing anthropogenic climate change that could play a disproportionate role in the threat that rapid environmental shifts pose to natural populations. Methods We exposed plants originating from seeds that were harvested before (ancestors) and after (descendants) multiple extreme heat events

Unexpected Dual Function of Plant YUCCA Enzymes Links Chlorophyll Catabolism to Auxin Homeostasis

Angewandte Chemie, EarlyView.
YUCCA enzymes are well known to catalyze the main step of auxin biosynthesis in plants. Here, a hitherto undescribed dual function was discovered, revealing that some YUCCAs also act in chlorophyll degradation. In vitro feedback regulation furthermore suggests a link between chlorophyll degradation and hormone homeostasis and a physiological role of ...

Wind‐driven seed dispersal differentially promotes seed trapping and retention across alpine plants

American Journal of Botany, EarlyView.
Abstract Premise Seed dispersal can mediate species interactions between plants across life stages. Plants can physically stop seed movement (seed trapping) and prevent further dispersal following entrapment (seed retention). We therefore hypothesized seed trapping and retention rates depend on the physical attributes of interacting seeds and plants ...
