Organic Electrolyte Composed of Strongly and Weakly Coordinating Molecules for Sodium‐Ion Battery. A Molecular Dynamics Simulation Study

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.
Molecular dynamics simulations reveal that the addition of weakly coordinating solvents disrupts stable Na+ solvation with various coordinating configurations, accelerating solvents exchange and promoting Na+ migration. The optimized electrolyte achieves the highest ionic conductivity as well as the fractional ionic conductivity of Na+ of 3.68 ± 0.36 ...

A Bayesian Spatiotemporal Functional Model for Data With Block Structure and Repeated Measures

open access: yesEnvironmetrics, Volume 37, Issue 2, March 2026.
ABSTRACT The analysis of spatiotemporal data is fundamental across multiple scientific disciplines, particularly in assessing the behavior of climate effects over space and time. A key challenge in this area is effectively capturing recurring climate phenomena, such as El Niño/La Niña (ENSO) phases, which induce prolonged periods of similar weather ...

Implicit Third‐Order Peer Triplets with Variable Stepsizes for Gradient‐Based Solutions in Large‐Scale ODE‐Constrained Optimal Control

open access: yesOptimal Control Applications and Methods, Volume 47, Issue 2, Page 570-588, March/April 2026.
Implicit third‐order Peer two‐step methods that are superconvergent for variable stepsizes have the potential to significantly improve the efficiency of solving large‐scale ODE‐constrained optimal control problems. These include real‐world applications in medical treatment planning for prostate cancer, such as the design of effective three‐dose drug ...

Methods Based on Polynomial Chaos for Quadratic Delay Differential Equations With Random Parameters

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT We consider systems of delay differential equations (DDEs), including a single delay and a quadratic right‐hand side. In a system, parameters are replaced by random variables to perform an uncertainty quantification. Thus the solution of the DDEs becomes a random process, which can be represented by a series of the generalised polynomial chaos.

Invariant theory of projective reflection groups, and their Kronecker coefficients

open access: yes, 2009
We introduce the class of projective reflection groups which includes all complex reflection groups. We show that several aspects involving the relationship between the combinatorics and the (invariant) representation theory of all non exceptional irreducible complex reflection groups find a natural description in this wider setting.

Enhancing Robustness in Finite‐Strain Crystal Plasticity: An Interior Point Method With Sequential Rotation Updates

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT Crystal plasticity simulations offer insights into the anisotropic deformation of polycrystalline materials such as metals and alloys. However, rate‐independent crystal plasticity models encounter the Taylor ambiguity, where the active slip systems and plastic slip magnitudes are not uniquely defined, posing well‐known numerical challenges [1].
