Product Structure and Tree-Decompositions

open access: yesCoRR
This paper explores the structure of graphs defined by an excluded minor or an excluded odd minor through the lens of graph products and tree-decompositions. We prove that every graph excluding a fixed odd minor is contained in the strong product of two graphs each with bounded treewidth.

Adaptive Foam 3D Printing of Ultralight and Multifunctional Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Adaptive foam 3D printing, enabled by expandable microspheres, imparts cellular structures to thermoplastic and thermosetting polymers, manufactured through a variety of processes including fused filament fabrication, direct ink writing, digital light processing, and inkjet printing.

Cell decompositions of C-minimal structures

open access: yesAnnals of Pure and Applied Logic, 1994
\(C\)-minimality is a variant of \(o\)-minimality in which structures carry, instead of a linear ordering, a ternary relation interpretable in a natural way on a set of maximal chains of a tree. This notion is discussed, a cell-decomposition theorem for \(C\)-minimal structures is proved, and a notion of dimension is introduced. It is shown that \(C\)-

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

open access: yesAdvanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Investigating the Low‐Temperature Phase Stability of the Binary Ta–W System

open access: yesAdvanced Engineering Materials, EarlyView.
Atomistic simulations show that the binary Ta–W system forms ordered intermetallic phases, B2‐TaW and D03‐TaW3, as 0 K ground states. Configurational entropy, however, lowers the free energy of the disordered bcc solid solution, which becomes the stable phase above about 400 K.

Structural decomposition analysis and index number theory: an empirical application of the Montgomery decomposition. [PDF]

open access: yes
In recent years a large number of empirical articles on structural decomposition analysis, which aims at disentangling an aggregate change into its factors, has been published in Economic Systems Research.

Structural Decomposition of Multi-Horizon Resource Allocation: Coupled Dynamics Toward Emergent Equilibrium

open access: yesSystems
Resource allocation exhibits systematic divergence across heterogeneous time horizons, which aggregate measures fail to capture. This paper models allocation as a multi-component dynamic system composed of three coupled mechanisms: long-term accumulation,

How circular is a directed network? A flow decomposition approach [PDF]

open access: yesRoyal Society Open Science
We introduce Circular Directional Flow Decomposition (CDFD), a new framework for analysing circularity in weighted directed networks. CDFD separates flow into two components: a circular (divergence-free) component and an acyclic component that carries ...

A Structural Decomposition for Hypergraphs

open access: yes, 1994
Hypergraphs arise in a variety of applications and are commonly classified as cyclic or acyclic. In this paper we develop a more refined classification scheme for cyclic hypergraphs based on a natural decomposition strategy. The fundamental building blocks in our decompositions are subsets of edges known as k-hinges.

High‐Entropy Alloy Interlayers Toward Advanced Joining for High‐Performance Structural Applications: Current Progress and Emerging Challenges

open access: yesAdvanced Engineering Materials, EarlyView.
HEA interlayers offer a versatile route for joining high‐performance structural materials. Their compositional and structural design regulates interfacial reactions, suppresses brittle IMCs, and improves metallurgical bonding. Sandwich interlayers further integrate defect healing with precipitation strengthening, enabling improved strength–ductility ...
