Bi-orthogonal Polynomials and the Five parameter Asymmetric Simple Exclusion Process

open access: yes, 1930
We apply the bi-moment determinant method to compute a representation of the matrix product algebra -- a quadratic algebra satisfied by the operators $\mathbf{d}$ and $\mathbf{e}$ -- for the five parameter ($\alpha$, $\beta$, $\gamma$, $\delta$ and $q ...

Static Scaling Behavior of High-Molecular-Weight Polymers in Dilute Solution: A Reexamination

open access: yes, 1993
Previous theories of dilute polymer solutions have failed to distinguish clearly between two very different ways of taking the long-chain limit: (I) $N \to\infty$ at fixed temperature $T$, and (II) $N \to\infty$, $T \to T_\theta$ with $x \equiv N^\phi (T-

A pan‐European citizen science study shows population size, climate and land use are related to biased morph ratios in the heterostylous plant Primula veris

open access: yesJournal of Ecology, Volume 114, Issue 1, January 2026.
A large‐scale citizen science study involving thousands of cowslip (Primula veris) observations from all over Europe revealed an unexpected prevalence of S‐morphs over L‐morphs, which was influenced by climatic as well as land use factors. Furthermore, general morph ratios were often unbalanced with the strongest shifts occurring in smaller populations.

Staircase polygons: moments of diagonal lengths and column heights

open access: yes, 2006
We consider staircase polygons, counted by perimeter and sums of k-th powers of their diagonal lengths, k being a positive integer. We derive limit distributions for these parameters in the limit of large perimeter and compare the results to Monte-Carlo ...

Exact Results for Hamiltonian Walks from the Solution of the Fully Packed Loop Model on the Honeycomb Lattice

open access: yes, 1994
We derive the nested Bethe Ansatz solution of the fully packed O($n$) loop model on the honeycomb lattice. From this solution we derive the bulk free energy per site along with the central charge and geometric scaling dimensions describing the critical ...
