Impact of Self-Loops on the Determinant of Graphs

Journal of Mathematics
The current theoretical study intends to analyze the determinant of a certain class of graphs with self-loops. This study focuses on a vast unexplored area of adjacency matrices with nonzero diagonal entities.

A Refined Graph Container Lemma and Applications to the Hard‐Core Model on Bipartite Expanders

Random Structures &Algorithms, Volume 68, Issue 1, January 2026.
ABSTRACT We establish a refined version of a graph container lemma due to Galvin and discuss several applications related to the hard‐core model on bipartite expander graphs. Given a graph G$$ G $$ and λ>0$$ \lambda >0 $$, the hard‐core model on G$$ G $$ at activity λ$$ \lambda $$ is the probability distribution μG,λ$$ {\mu}_{G,\lambda } $$ on ...

Counting Independent Sets in Percolated Graphs via the Ising Model

Random Structures &Algorithms, Volume 68, Issue 1, January 2026.
ABSTRACT Given a graph G$$ G $$, we form a random subgraph Gp$$ {G}_p $$ by including each edge of G$$ G $$ independently with probability p$$ p $$. We provide an asymptotic expansion of the expected number of independent sets in random subgraphs of regular bipartite graphs satisfying certain vertex‐isoperimetric properties, extending the work of ...

Enhanced Modelling and Analysis of Cyber‐Physical System Security Against DoS Attacks Using Generalised Stochastic Petri Nets

IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.
This paper proposes a new framework for the analysis of cyber‐physical system security against denial‐of‐service (DoS) attacks using generalised stochastic Petri nets. The model incorporates immediate and timed transitions, thus mapping both continuous operations of cyber‐physical system and discrete‐event natures of cyber threats.

Plant functional traits affect invertebrate predator diversity via bottom‐up effects in a deadwood‐based food web

Functional Ecology, Volume 40, Issue 1, Page 128-139, January 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Bottom‐up effects play a critical role in shaping community structure and trophic interactions within detritus‐based food webs. Coarse deadwood supports high biodiversity and contributes to detrital food webs during its decomposition process.
