Tensorial generalization of characters
Journal of High Energy Physics, 2019 In rainbow tensor models, which generalize rectangular complex matrix model (RCM) and possess a huge gauge symmetry U(N 1) × … × U(N r ), we introduce a new sub-basis in the linear space of gauge invariant operators, which is a redundant basis in the ...

Tensor-based approach to the co-prime planar array signal processing
Tongxin xuebao, 2020 For the co-prime planar array (CPPA) consisting of two sparse uniform rectangular array (URA),a new processing method based on tensor algebra was proposed to enhance the degrees of freedom (DoF).By dividing each URA into some overlapping subarrays,the ...

Broad-Band Measurement of all Complex Permeability Tensor Components and Complex Permittivity of Ferrites using a Rectangular Waveguide [PDF]
Le Journal de Physique IV, 1997 We have worked out a broad-band characterization method for magnetized ferrimagnetic materials. The technique is based on the reflection/transmission measurement of the S-parameters of a rectangular waveguide partly loaded with a ferrite that is to be characterized. The device is set in between the poles of an electromagnet to magnetize the sample. The

Convergence of an algorithm for the largest singular value of a nonnegative rectangular tensor
Linear Algebra and its Applications, 2013 The authors present an iterative algorithm for computing the largest singular value of a nonnegative rectangular tensor. The convergence of this algorithm for any irreductibile nonnegative rectangular tensor is also proved.

Sedimentation dynamics of triply twisted Möbius bands: Geometry versus topology
Physical Review ResearchWe explore the sedimentation dynamics of triply twisted Möbius bands, each characterized by threefold rotational symmetry but distinguished by its construction and intrinsic geometrical properties.

Two stage multiobjective topology optimization method via SwinUnet with enhanced generalization
Scientific ReportsTopology optimization is a critical tool for modern structural design, yet existing methods often prioritize single objectives (e.g., compliance minimization) and suffer from prohibitive computational costs, especially in multi-objective scenarios.

A tighter S-type singular value inclusion set for rectangular tensors
, 2017 A new S-type singular value inclusion set for rectangular tensors is given and proved to be tighter than that in [Sang C.L., An S-type singular value inclusion set for rectangular tensors, J. Inequal. Appl. 2017: 141, 2017]. Based on this set, new bounds for the largest singular value of nonnegative rectangular tensors are obtained and proved to be ...

Jurnal Teknologi, 2016 The applications of real rectangular tensors, among others, including the strong ellipticity condition problem within solid mechanics, and the entanglement problem within quantum physics. A method was suggested by Zhou, Caccetta and Qi in 2013, as a means of calculating the largest singular value of a nonnegative rectangular tensor.
