BC tree-based spectral sampling for big complex network visualization
Graph sampling methods have been used to reduce the size and complexity of big complex networks for graph mining and visualization. However, existing graph sampling methods often fail to preserve the connectivity and important structures of the original ...

Decomposing 8-regular graphs into paths of length 4
A $T$-decomposition of a graph $G$ is a set of edge-disjoint copies of $T$ in $G$ that cover the edge set of $G$. Graham and H\"aggkvist (1989) conjectured that any $2\ell$-regular graph $G$ admits a $T$-decomposition if $T$ is a tree with $\ell$ edges ...

By combining porous, solid, and carbon fiber‐reinforced thermoplastic polyurethane within a single 3D printed honeycomb structure, this current work achieved precise control over spatial stiffness while ensuring strong interlayer adhesion. The findings demonstrate enhanced energy absorption and densification strain, outperforming traditional uniform ...

Heat treatment parameters critically affect the wear resistance of powder bed fusion–laser beam (PBF‐LB)‐produced Ti–6Al–2Sn–4Zr–6Mo alloy. This study found that optimizing annealing temperature allows to obtain a tailored microstructure, which enhances the dry‐sliding behavior by forming a stable and functional mechanically mixed layer (MML), ensuring

A near infrared‐responsive microscale cantilever is developed using a 3D‐printable composite based on photocurable resin consisting of sepiolite and graphene flakes. The material absorbs 1064 nm light, causing shape transformation with an average displacement of 1.3 mm in 1.7 s. Displacement is measured via video recording.

Star-Supermagic Decompositions of the Complete Bipartite Graph Minus a One-Factor
Let G be a graph and let H be a subgraph of G. Assume that G has an H-decomposition T={H1,H2,…,Ht} such that Hi≅H for all 1≤i≤t. An H-supermagic decomposition of G is a bijection f:V(G)∪E(G)→1,2,…,VG+EG such that ∑v∈V(Hi)f(v)+∑e∈E(Hi)f(e) is a constant k

A highly stable, low‐temperature phosphate glass is developed for multimaterial additive manufacturing of multifunctional microfluidics. Glass, metal conductors, and sacrificial polymer are coprinted, enabling monolithic fabrication. The sacrificial paste forms precise channels and decomposes during sintering.

Connection and separation in hypergraphs
In this paper we study various fundamental connectivity properties of hypergraphs from a graph-theoretic perspective, with the emphasis on cut edges, cut vertices, and blocks. We prove a number of new results involving these concepts.

Tangles of graphs have been introduced by Robertson and Seymour in the context of their graph minor theory. Tangles may be viewed as describing "k-connected components" of a graph (though in a twisted way).
