Knowledge Distillation‐Based Zero‐Shot Learning for Process Fault Diagnosis
Advanced Intelligent Systems, EarlyView.Process and image data are equivalent with the teacher model pretrained on image data. Knowledge distillation transfers normal condition data to the student model. When an unknown fault occurs, differences between the teacher and student models are quantified via gradients to isolate the fault. Data‐driven deep learning is effective in diagnosing known

NMR in Biomedicine, Volume 36, Issue 1, January 2023., 2023 A 3D, density‐weighted, concentric rings trajectory MRSI sequence is implemented for fast cardiac 31P‐MRS at 7 T. The sequence is evaluated at five acquisition times in the hearts of healthy participants. To mitigate the low signal‐to‐noise ratio of short acquisitions, low‐rank denoising was evaluated as a postacquisition step and found to lower ...

International Journal for Numerical Methods in Engineering, Volume 124, Issue 3, Page 714-751, 15 February 2023., 2023 Abstract In this work we present a novel monolithic Finite Element method for the hydroelastic analysis of very large floating structures (VLFS) with arbitrary shapes that is stable, energy conserving, and overcomes the need of an iterative algorithm. The new formulation enables a fully monolithic solution of the linear free‐surface flow, described by ...

A nonlinear elliptic equation with singular potential and applications to nonlinear field equations
Journal of the European Mathematical Society, 2007 We study existence and asymptotic properties of solutions to a semilinear elliptic equation in the whole space. The equation has a cylindrical symmetry and we find cylindrical solutions. The main features of the problem are that the potential has a large set of singularities (i.e. a subspace), and that the nonlinearity has a double power-like behaviour,

Modulational Instability and Dynamical Growth Blockade in the Nonlinear Hatano–Nelson Model
Advanced Physics Research, EarlyView.The nonlinear Hatano–Nelson model under periodic boundary conditions is investigated, revealing a novel growth blockade phenomenon triggered by the modulational instability of nonlinear plane waves. This effect, characterized by the abrupt halt of norm growth, arises from self‐induced disorder, marking a departure from the convective motion observed in

Recent Advances in Dielectric Chiral Metasurfaces
Advanced Physics Research, EarlyView.This review article mainly focuses on the recent advances in dielectric chiral metasurfaces, which exhibit remarkable optical chirality. Many new physical conceptions will be introduced during the fast development of the dielectric chiral metasurfaces, such as chiral quasi‐BIC, chiral guided modes, and nonlocal metasurfaces.
