Quantum-assisted optical interferometers: instrument requirements [PDF]

Astronomical Telescopes + Instrumentation, 2020
It has been recently suggested that optical interferometers may not require a phase-stable optical link between the stations if instead sources of quantum-mechanically entangled pairs could be provided to them, enabling extra- long baselines and ...

The Robotic Multiobject Focal Plane System of the Dark Energy Spectroscopic Instrument (DESI) [PDF]

Astronomical Journal, 2022
A system of 5020 robotic fiber positioners was installed in 2019 on the Mayall Telescope, at Kitt Peak National Observatory. The robots automatically retarget their optical fibers every 10–20 minutes, each to a precision of several microns, with a ...

Multimodal predictive classification of Alzheimer's disease based on attention‐combined fusion network: Integrated neuroimaging modalities and medical examination data

IET Image Processing, 2023
Early diagnosis of Alzheimer's disease (AD) plays a key role in preventing and responding to this neurodegenerative disease. It has shown that, compared with a single imaging modality‐based classification of AD, synergy exploration among multimodal ...

Efficient Compound Activity Prediction Model Based on Bayesian Regularization Method for Candidate Drugs

IEEE Access, 2022
In breast cancer diagnoses, antagonist compounds are used to resist $\alpha $ Subtype of Estrogen Receptor (ER $\alpha$ ) bioactivity. However, those compounds are difficult to be obtained in the process of drug screening.
