Summary: Electrochemical fingerprinting is a new plant analysis technology that can be used to study genetic differences between different species. In this study, 19 Quercus species were investigated using electrochemical fingerprinting, and the results showed that the fingerprint of some species share similar features but can still be distinguished by changing the recording conditions. These electrochemical fingerprints were further used to construct different pattern recognition technology, which increased the recognition efficiency. The phylogenetic results deduced from electrochemical fingerprinting divided the Quercus species mainly into three clusters, providing evidence for genetic relationships between the species.

Summary: The recent advances in optic neuromorphic devices have enabled the development of energy-efficient artificial-vision systems. These devices are widely used due to their ability to capture, store, and process visual information. However, existing optic neuromorphic devices have limitations such as nonlinear weight updates, cross-talk issues, and silicon process incompatibility. This study introduces a highly linear, light-tunable, cross-talk-free, and silicon-compatible optic memristor for the implementation of an optic artificial neural network (OANN). The experimental results show that the OANN achieves an accuracy of 99.3% after ten training epochs, demonstrating the effectiveness of the proposed optic memristor as a hardware solution for efficient optic neuromorphic and edge computing.
