Characteristic Min-Polynomial and Eigen Problem of a Matrix over Min-Plus Algebra
JTAM (Jurnal Teori dan Aplikasi Matematika), 2023 Let R_ε=R∪{-∞}, with R being a set of all real numbers. The algebraic structure (R_ε,⊕,⊗) is called max-plus algebra. The task of finding the eigenvalue and eigenvector is called the eigenproblem.

Advanced Functional Materials, EarlyView.From a database of 170 pentagonal 2D materials, 4 candidates exhibiting altermagnetic ordering are screened. Furthermore, the spin‐splitting and unconventional boundary states in the pentagonal 2D altermagnetic monolayer MnS2 are investigated. A MnS2‐based altermagnetic tunneling junction is designed and, through ab initio quantum transport simulations,

Advanced Functional Materials, EarlyView.This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

On a frame theoretic measure of quality of LTI systems
, 2017 It is of practical significance to define the notion of a measure of quality of a control system, i.e., a quantitative extension of the classical notion of controllability.

Cell Surface Thiol Engineering Mechanoregulates Myogenic Differentiation via the FAK–PI3K–AKT Axis
Advanced Healthcare Materials, EarlyView.Schematic diagram illustrating how cell surface modification of skeletal muscle progenitor cells through TCEP treatment reveals enhanced cell adhesion, intracellular tension, and myogenesis at 19.66 kPa stiffness, leading to optimal cell fusion. In contrast, no significant changes are observed in the softer (10.61 kPa) or stiffer (49.4 kPa) matrices ...

Existence of a principal eigenvalue for the Tricomi problem
Electronic Journal of Differential Equations, 2000 The existence of a principal eigenvalue is established for the Tricomi problem in normal domains; that is, the existence of a positive eigenvalue of minimum modulus with an associated positive eigenfunction.

New inequalities on the Fan product of M-matrices
Journal of Inequalities and ApplicationsThis paper focuses on the minimum eigenvalue involving the Fan product. By utilizing the Hölder inequality and the classic eigenvalue inclusion theorem, we introduce two novel lower bounds for τ ( A 1 ⋆ A 2 ) $\tau \left ( A_{1}\star A_{2} \right ...

Spatiotemporally Resolved Orbital Hall Effect in a Topological Semimetal
Advanced Materials, EarlyView.Real‐space mapping of orbital angular momentum (OAM) transport is achieved using contact‐free polarimetric terahertz spectroscopy. This principle is applied to the topological semimetal Td‐WTe2, revealing the spatial separation of electrons into two distinct regions characterized by opposite out‐of‐plane OAM (±Lz).

Ordering non-bipartite unicyclic graphs with pendant vertices by the least Q-eigenvalue
Journal of Inequalities and Applications, 2016 A unicyclic graph is a connected graph whose number of edges is equal to the number of vertices. Fan et al. (Discrete Math. 313:903-909, 2013) and Liu et al. (Electron. J.
