Environmetrics, Volume 37, Issue 6, September 2026.ABSTRACT This discussion focuses on unique two aspects of the study: The use of the generalized pareto distribution to extrapolate below a threshold and the tension that exists between extreme value methods and the desire to provide an upper bound.

Some recent work in Frechet geometry [PDF]
, 2011 Some recent work in Frechet geometry is briefly reviewed. In particular an earlier result on the structure of second tangent bundles in the finite dimensional case was extended to infinite dimensional Banach manifolds and Frechet manifolds that could be ...

Models for Temporal Clustering of Extreme Events With Applications to Mid‐Latitude Winter Cyclones
Environmetrics, Volume 37, Issue 6, September 2026.ABSTRACT The occurrence of extreme events like heavy precipitation or storms at a certain location often shows a clustering behavior and is thus not described well by a Poisson process. We construct a general model for the inter‐exceedance times (IETs) in between extreme events which combines different candidate models for such behavior. One of them is

Macromolecular Materials and Engineering, Volume 311, Issue 9, September 2026.AI is reshaping the design and modeling of organic electrochemical energy materials, from redox‐active molecules to polymer electrolytes. Progress across data‐driven prediction, machine‐learning interatomic potentials, generative models, and agentic workflows is assessed, while persistent challenges in data quality, polymer representation, validation ...

Remarks on the Generation of Semigroups of Nonlinear Operators on p-Fréchet Spaces, 0 < p < 1
Cubo, 2011 In this paper we study the convergence properties of the Crandall-Liggett sequence , for A a nonlinear operator on some important non-locally convex F-spaces (called p-Fréchet spaces with 0 < p < 1) and the generation of the corresponding strongly ...

Model Predictive Control of Gas Networks Based on Port‐Hamiltonian Formulations
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 3, September 2026.ABSTRACT To efficiently compute optimal compressor actions in gas networks, we investigate port‐Hamiltonian models consisting of linear and a nonlinear model assumptions. The control actions are derived via adjoint‐based gradients that incorporate the constraints of the underlying optimization problem. We then present results from the implementation of

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract Megathrust slip behavior in subduction zones can vary along‐strike, yet the mechanisms driving this variability remain uncertain. The Middle America trench offshore Mexico provides an ideal setting to investigate the structural controls on megathrust slip behavior.

Investigating Layered Cratonic Lithosphere in the Fennoscandian Shield
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract Cold, thick, and chemically depleted lithosphere with high seismic velocity and low attenuation characterizes continental cratons. However, discrepancies between xenolith‐based thermal constraints and those inferred from surface‐wave seismic models, together with the widespread observation of mid‐lithosphere discontinuities, challenge the ...
