Raman Spectra and Bulk Modulus of Nanodiamond in a Size Interval of 2–5 nm

Nanoscale Research Letters, 2017
Nanodiamond in a 2–5-nm size interval (which is typical for an appearance of quantum confinement effect) show Raman spectra composed of 3 bands at 1325, 1600, and 1500 cm−1 (at the 458-nm laser excitation) which shifts to 1630 cm−1 at the 257-nm laser ...

Elastic temporal alignment for few‐shot action recognition

IET Computer Vision, 2023
Few‐shot action recognition aims to learn a classification model with good generalisation ability when trained with only a few labelled videos. However, it is difficult to learn discriminative feature representations for videos in such a setting.

Receptor Recognition by the Novel Coronavirus from Wuhan: an Analysis Based on Decade-Long Structural Studies of SARS Coronavirus

Journal of Virology, 2020
The recent emergence of Wuhan coronavirus (2019-nCoV) puts the world on alert. 2019-nCoV is reminiscent of the SARS-CoV outbreak in 2002 to 2003. Our decade-long structural studies on the receptor recognition by SARS-CoV have identified key interactions ...

Risk Minimization Against Transmission Failures of Federated Learning in Mobile Edge Networks

IEEE Access, 2020
A variety of modern AI products essentially require raw user data for training diverse machine learning models. With the increasing concern on data privacy, federated learning, a decentralized learning framework, enables privacy-preserving training of ...

COG6‐CDG: Novel variants and novel malformation [PDF]

Birth Defects Research, 2022
AbstractBackgroundDeficiency of Conserved Oligomeric Golgi (COG) subunits (COG1–8) is characterized by both N‐ and O‐protein glycosylation defects associated with destabilization and mislocalization of Golgi glycosylation machinery components (COG‐CDG).

Genomic characterization of the 2019 novel human-pathogenic coronavirus isolated from a patient with atypical pneumonia after visiting Wuhan

Emerging Microbes and Infections, 2020
A mysterious outbreak of atypical pneumonia in late 2019 was traced to a seafood wholesale market in Wuhan of China. Within a few weeks, a novel coronavirus tentatively named as 2019 novel coronavirus (2019-nCoV) was announced by the World Health ...

Simulation of the effect of polarization Coulomb field scattering on device linearity in AlGaN/GaN heterostructure field effect transistors using the Monte Carlo method

AIP Advances, 2021
This paper demonstrates the improvement of device linearity in AlGaN/GaN heterostructure field effect transistors (HFETs) using polarization Coulomb field (PCF) scattering and investigates the relationship between device linearity and PCF scattering ...

A mathematical explanation via "intelligent" PID controllers of the strange ubiquity of PIDs [PDF]

, 2010
The ubiquity of PID controllers in the industry has remained mysterious until now. We provide here a mathematical explanation of this strange phenomenon by comparing their sampling with the the one of "intelligent" PID controllers, which were recently ...
