Enhanced premelting at the ice-rubber interface using all-atom molecular dynamics simulation
arXiv:2508.20448v2 Announce Type: replace-cross Abstract: The ice-rubber interface is critical in applications such as tires and shoe outsoles, yet its molecular tribology remains unclear. Using all-atom molecular dynamics simulations, we studied premelting layers at the basal face of ice in contact with styrene-butadi...

Setting limits on blazar-boosted dark matter with xenon-based detectors
arXiv:2509.07265v2 Announce Type: replace-cross Abstract: Dual-phase xenon time-projection chambers achieve optimal sensitivity to dark matter in the mass range from about 10 to 1000~GeV/$c^{2}$. However, sub-GeV dark-matter particles do not produce nuclear recoils above detection thresholds in these detectors. Blazar-...

On the finiteness of the group associated with weighted walks in multidimensional orthants
arXiv:2512.24027v1 Announce Type: new Abstract: In the study of walks with small steps confined to multidimensional orthants, a certain group of transformations plays a central role. In particular, several techniques to potentially compute the generating function, including the orbit sum method, can only be applied whe...

Spanning Components and Surfaces Under Minimum Vertex Degree
arXiv:2512.24242v1 Announce Type: new Abstract: We study minimum vertex-degree conditions in 3-uniform hypergraphs for (tight) spanning components and (combinatorial) surfaces. Our main results show that a 3-uniform hypergraph $G$ on $n$ vertices contains a spanning component if $\delta_1(G) \gtrsim \tfrac{1}{2} \binom...

On the Consistency of Combinatorially Symmetric Sign Patterns and the Class of 2-Consistent Sign Patterns
arXiv:2512.24248v1 Announce Type: new Abstract: A sign pattern is a matrix that has entries from the set $\{+,-,0\}$. An $n\times n$ sign pattern $\mathcal{P}$ is called consistent if every real matrix in its qualitative class has exactly $k$ real eigenvalues and $n-k$ nonreal eigenvalues for some integer $k$, with $1\...

This construction provides a cleaner, compact and non-redund...

Construction of sign k-potent sign patterns and conditions for such sign patterns to allow k-potence
arXiv:2512.24264v1 Announce Type: new Abstract: A sign pattern is a matrix whose entries are from the set $\{+,-, 0\}$. A square sign pattern $A$ is called sign $k$-potent if $k$ is the smallest positive integer for which $A^{k+1}=A$, and for $k=1$, $A$ is called sign idempotent. In 1993, Eschenbach \cite{01} gave an a...
