Linking Biotic Interactions to Species Stability

Ecology Letters, Volume 29, Issue 4, April 2026.
We develop a unifying framework that predicts how species respond to environmental disturbances by linking species‐level stability to a single quantity: self‐regulation loss (SL). Using analytical results, simulations, and experimental protist communities, we show that SL accurately predicts both sensitivity to press disturbances and recovery from ...

Scientists' Warning on the Rapid Evolution of Parasites in the Anthropocene

Evolutionary Applications, Volume 19, Issue 4, April 2026.
ABSTRACT Human activities are changing the natural world at an accelerating pace, and as a consequence exerting novel and often strong selection pressures on living organisms. For species with traits conferring huge inherent evolutionary potential, like parasites, the outcome may be rapid adaptive responses spanning multiple phenotypic traits. The rise

Application of data-driven model reduction techniques in reactor neutron field calculations

Nuclear Engineering and Technology
High-order harmonic techniques can be used to recreate neutron flux distributions in reactor cores using the neutron diffusion equation. However, traditional source iteration and source correction iteration techniques have sluggish convergence rates and ...

An Arnoldi like method for the delay eigenvalue problem

, 2010
The method called Arnoldi is currently a very popular method to solve large-scale eigenvalue problems. The general purpose of this paper is to generalize Arnoldi to the characteristic equation of a delay-differential equation (DDE), here called a delay ...

Restarting for the Tensor Infinite Arnoldi method

, 2016
An efficient and robust restart strategy is important for any Krylov-based method for eigenvalue problems. The tensor infinite Arnoldi method (TIAR) is a Krylov-based method for solving nonlinear eigenvalue problems (NEPs). This method can be interpreted as an Arnoldi method applied to a linear and infinite dimensional eigenvalue problem where the ...

On a fast Arnoldi method for BML matrices

, 2017
Matrices whose adjoint is a low rank perturbation of a rational function of the matrix naturally arise when trying to extend the well known Faber-Manteuffel theorem, which provides necessary and sufficient conditions for the existence of a short Arnoldi recurrence.

Improving Eigenvectors in Arnoldi's Method

, 2007
The Ritz vectors obtained by Arnoldi's method may not be good approximations and even may not converge even if the corresponding Ritz values do. In order to improve the quality of Ritz vectors and enhance the efficiency of Arnoldi type algorithms ...

Convergence analysis and parameter estimation for the iterated Arnoldi-Tikhonov method

The Arnoldi-Tikhonov method is a well-established regularization technique for solving large-scale ill-posed linear inverse problems. This method leverages the Arnoldi decomposition to reduce computational complexity by projecting the discretized problem
