A parallel multi‐block alternating direction method of multipliers for tensor completion

IET Image Processing, 2021
This paper proposes an algorithm for the tensor completion problem of estimating multi‐linear data under the limitation of observation rate. Many tensor completion methods are based on nuclear norm minimization, they may fail to achieve the global ...

Photon minibeam‐based LATTICE radiotherapy for small and medium‐sized tumors: A dosimetric planning study

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Lattice radiotherapy (LRT) is a spatially fractionated technique that delivers three‐dimensional high‐dose vertices within tumors. However, conventional LRT is constrained by geometric limitations when applied to small and medium‐sized tumor volumes, primarily due to the large beam sizes that restrict optimal lattice pattern ...

Water/Fat Separated Echo Planar Time‐Resolved Imaging (WFS‐EPTI) for Distortion‐Free Multi‐Contrast MRI

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 580-595, August 2026.
ABSTRACT Purpose Echo‐planar time‐resolved imaging (EPTI) provides distortion‐ and T2/T2* blurring‐free multi‐echo/multi‐contrast imaging with fast speed, making it an efficient acquisition method for various MRI applications. Here, we aim to achieve water–fat separation for EPTI to improve fat signal removal for brain/body imaging applications. Theory

Alternating Direction Method of Multipliers (ADMM) for Frictional Contact

, 2019
In this report, we review the quadratic programming (QP) over second-order cones formulation of the discrete frictional contact problem that arises in space and time discretized mechanical systems with unilateral contact and three-dimensional Coulomb's friction.

Recognition of Spatiotemporal Feature Images of Zero‐Sequence Voltage for Single‐Phase High‐Impedance Ground Faults Under Complex Conditions

High Voltage, Volume 11, Issue 4, Page 1129-1142, August 2026.
ABSTRACT Diagnosing high‐impedance ground faults (HIGFs) in distribution networks is extremely challenging because high transition resistance significantly reduces electrical signal strength and unpredictable initial fault phase angles coupled with asymmetric voltage disturbances often lead to misclassification.

Pixel‐Level Inversion Assessment for Ageing of Composite Insulator Sheds of Power System

High Voltage, Volume 11, Issue 4, Page 1021-1031, August 2026.
ABSTRACT The polymeric materials used in insulator sheds are prone to ageing under different environmental conditions, which can lead to flashovers and grid outages. The ageing process in composite insulators primarily involves changes in the microscopic properties of the materials.
