Exponent-Incidence Constraints for Tensor Eigenvectors of Multi-Hypergraphs

Mathematics
We study support-determined constraints for eigenvectors of nonnegative symmetric tensors whose support may contain repeated indices. Such tensors are naturally encoded by uniform multi-hypergraphs, where each multiedge is represented by an exponent ...

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

Advanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Graph Neural Network of Multiple Diagonal Constraints for Sound Event Detection

IEEE Access
Acoustic signals originating from distinct sources inherently exhibit diverse spectral and temporal characteristics. In this study, we propose a novel framework, termed the graph neural network of multiple diagonal constraints (GMDC), which is designed ...

Mapping functional brain networks from the structural connectome: Relating the series expansion and eigenmode approaches

NeuroImage, 2020
Functional brain networks are shaped and constrained by the underlying structural network. However, functional networks are not merely a one-to-one reflection of the structural network.

Triple Junctions as Dislocation‐Like Defects: The Role of Grain Boundary Crystallography Revealed by Experiment and Atomistic Simulation

Advanced Engineering Materials, EarlyView.
Grain boundary triple junctions are an essential ingredient of the microstructure of polycrystalline materials. In this study, a triple junction is observed using atomic‐resolution scanning transmission electron microscopy and characterized. Computer simulations reveal that the junction has a dislocation character that is determined by the joining ...

Spectral radius of extended adjacency tensor of uniform hypergraphs

Boletim da Sociedade Paranaense de Matemática
Hypergraphs are a useful tool in chemistry for representing intricate molecular structures and their interactions. The topological indices of hypergraphs provide valuable insights into the structural characteristics of complex molecular systems. The tensor representations are more preferred than the matrix representations of hypergraphs since they ...

Continuous Stiffness Graded Metal–Ceramic Femoral Stems: UMAT‐Based Design and Finite Element Assessment

Advanced Engineering Materials, EarlyView.
Functionally graded metal–ceramic femoral stems are engineered through continuous UMAT‐based stiffness tailoring, eliminating discrete material interfaces while enhancing biomechanical compatibility. Low‐index power‐law gradation optimizes load transfer, reduces stress shielding, and controls implant–bone micromotion, highlighting a materials‐design ...

Parameter Counts and Circuit Constraint Spaces in Spectral Hypergraph Theory

Mathematics
This paper studies eigenvector constraints for adjacency hypermatrices of uniform hypergraphs using matroid circuits. Building on Pearson’s circuit relations, we define the circuit constraint space L(H) as the span of all Pearson relation vectors ...

On the Effect of Creep on Local Lattice Orientation in Single‐Crystal Ni‐Based Superalloy Microstructures

Advanced Engineering Materials, EarlyView.
During creep of a single‐crystal Ni‐based superalloy, the overall crystal orientation is observed to remain constant while the microstructure evolves. Despite the lack of macroscopic rotation, small (<1°) rotations are observed on the submicron size scale and are accommodated by counteracting rotations over the scale of several micrometers.

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

Advanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,
