Synergistic Reconstruction and Synthesis via Generative Adversarial Networks for Accelerated Multi-Contrast MRI [PDF]

arXiv, 2018
Multi-contrast MRI acquisitions of an anatomy enrich the magnitude of information available for diagnosis. Yet, excessive scan times associated with additional contrasts may be a limiting factor. Two mainstream approaches for enhanced scan efficiency are reconstruction of undersampled acquisitions and synthesis of missing acquisitions.

Chiroferromagnetic Quantum Dots for Chiroptical Synapse (ChiropS)

Advanced Materials, EarlyView.
Chiroptical activity is enhanced by up to 0.003 in the g‐factor through the induction of ferromagnetism in quantum dots. A chiroptical neuromorphic synapse, composed of chiroferromagnetic quantum dots, generates different synaptic weights from multiple wavelengths and circularly polarized light.

Do computer vision foundation models learn the low-level characteristics of the human visual system? [PDF]

arXiv
Computer vision foundation models, such as DINO or OpenCLIP, are trained in a self-supervised manner on large image datasets. Analogously, substantial evidence suggests that the human visual system (HVS) is influenced by the statistical distribution of colors and patterns in the natural world, characteristics also present in the training data of ...

1.4% External Quantum Efficiency 988 nm Light Emitting Diode Based on Tin‐Lead Halide Perovskite

Advanced Materials, EarlyView.
The tin‐lead based halide perovskite film with the 3‐AMP passivate exhibits a significantly longer carrier lifetime of over 1 µs compared to the neat films (0.43 µs). The optimized tin‐lead halide perovskite LEDs show a single emission peak at 988 nm and an external quantum efficiency (EQE) of ≈1.4%.
