Dual-Output Mode Analysis of Multimode Laguerre-Gaussian Beams via Deep Learning
Optics, 2021 The Laguerre-Gaussian (LG) beam demonstrates great potential for optical communication due to its orthogonality between different eigenstates, and has gained increased research interest in recent years. Here, we propose a dual-output mode analysis method

Role of surface microgeometries on electron escape probability and secondary electron yield of metal surfaces [PDF]
, 2020 The influence of microgeometries on the Secondary Electron Yield (SEY) of surfaces is investigated. Laser written structures of different aspect ratio (height to width) on a copper surface tuned the SEY of the surface and reduced its value to less than ...

High-performance complementary resistive switching in ferroelectric film
AIP Advances, 2021 The complementary resistive switch (CRS) offers a promising logic-in-memory functionality and is a potential solution to the “von Neumann bottleneck” problem, but the CRS structure composed of two anti-serially connected bipolar resistive switching cells

Neural network-based prediction of the secret-key rate of quantum key distribution
Scientific Reports, 2022 Numerical methods are widely used to calculate the secure key rate of many quantum key distribution protocols in practice, but they consume many computing resources and are too time-consuming.

Gastroenterology, 1979 Electron microprobe analysis, x-ray diffraction, and infrared spectroscopy have been used to investigate the nature and arrangement of materials present in gallstones. Calcium phosphate and carbonate deposits present centrally in many stones were mixed with a pigmented phase containing copper and protein. In several stones, the central calcium deposits

Digital fingerprinting of microstructures
Computational Materials Science, 2023 Finding efficient means of fingerprinting microstructural information is a critical step towards harnessing data-centric machine learning approaches. A statistical framework is systematically developed for compressed characterisation of a population of images, which includes some classical computer vision methods as special cases.

Dielectric relaxation of interfacial polarizable molecules in chitosan ice-hydrogel materials
Journal of Materiomics, 2018 The functionalities of hydrogel-based smart materials are highly related to the electrostatic interactions and molecular polarization associated with the polymer networks and encapsulated water droplets, and therefore the dielectric responses of the ...

Multiphoton non-local quantum interference controlled by an undetected photon
Nature Communications, 2023 Usually, observation of quantum interference in a non-local scenario (that is, when Alice’s measurement settings and Bob’s outcomes are space-like separated) relies on entanglement.
