Dimer models and conformal structures
Communications on Pure and Applied Mathematics, Volume 79, Issue 2, Page 340-446, February 2026.Abstract Dimer models have been the focus of intense research efforts over the last years. Our paper grew out of an effort to develop new methods to study minimizers or the asymptotic height functions of general dimer models and the geometry of their frozen boundaries.

On the Q‐Polynomial Property of Bipartite Graphs Admitting a Uniform Structure
Journal of Combinatorial Designs, Volume 34, Issue 2, Page 69-86, February 2026.ABSTRACT Let Γ denote a finite, connected graph with vertex set X. Fix x ∈ X and let ε ≥ 3 denote the eccentricity of x. For mutually distinct scalars { θ i * } i = 0 ε define a diagonal matrix A * = A * ( θ 0 * , θ 1 * , … , θ ε * ) ∈ Mat X ( R ) as follows: for y ∈ X we let ( A * ) y y = θ ∂ ( x , y ) *, where ∂ denotes the shortest path length ...

Weak saturation numbers of K2 , t and K p ⋃ K q
AKCE International Journal of Graphs and Combinatorics, 2019 A graph G is weakly F-saturated if G contains no copy of F, and there is an ordering of all edges of G¯so that if they are added one at a time, they form a complete graph and each edge added creates a new copy of F.

Discrete Applied Mathematics, 1987 It is shown that bipartite permutation graphs have good algorithmic properties in contrast to general bipartite or permutation graphs. Two characterizations of these graphs are presented which lead to a linear time recognition algorithm and also to polynomial algorithms for Hamiltonian problems, a variant of the crossing number problem and the minimum ...

People and Nature, Volume 8, Issue 2, Page 283-300, February 2026.Abstract The Industrial Revolution triggered rural abandonment in Europe and had a profound impact on land configuration and ecosystem dynamics, mainly the growth of forests at the expense of open agricultural habitats. However, rural abandonment has been asynchronous in space and time, depending on regional socio‐economic dynamics.

The FEBS Journal, Volume 293, Issue 3, Page 894-917, February 2026.The plant hormone ethylene regulates plant growth, ripening, senescence, and stress responses. The hormonal signal transmission, from receptors at the ER membrane to the transcriptional regulators in the nucleus, is still not completely understood.
