In less than a decade since 1997, nanowires research has expanded into new application-driven areas, highlighting a significant shift toward more challenging and exploratory research avenues. It is therefore essential to reflect on the past motivations for nanowires development, and explore the new opportunities it can enable.

- A deep learning model was developed to detect and classify cervical cord signal abnormalities, spinal canal, and neural foraminal stenosis on MRI, aimed at improving reporting efficiency and consistency for cervical spondylosis.
- The study analyzed 504 cervical spine MRIs from a patient sample with a mean age of 58, using 90% for training and 10% for internal testing, with additional external testing on another 100 MRIs.
- Results showed the DL model achieved substantial agreement with human readers, outperforming them in classifying spinal canal and foraminal stenosis, and exhibited a high recall of 92.3% for cord signal abnormalities, demonstrating its potential effectiveness in clinical practice.
Article Synopsis
- Optoelectronic synapses combine light and electrical processes for artificial vision and computing but typically don't mimic real synaptic behavior due to a lack of chemical interactions.
- This research introduces a new synaptic device using nanowires that integrates these chemical-electric processes, achieving both short-term and long-term plasticity in synaptic operations.
- The device adapts to different chemical environments, successfully simulating complex biological reactions and showcasing its potential for advanced neuromorphic applications.
Here, we report the first utilization of covalent organic frameworks (COFs) in optical wireless communication (OWC) applications. In the solid form, aggregation-induced emission (AIE) luminogen often shows promising emissive characteristics that augment radiative decays and improve fluorescence. We have synthesized an through the Knoevenagel condensation reaction by taking advantage of the ability to carefully design and alter the COF structure by integrating an AIE luminogen with linear building blocks.
