Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

open access: yesAdvanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Uniform Convergence of Probability Measures: Topological Criteria [PDF]

open access: yes
Uniform convergence of probability measures is analyzed by topologizing the space of events. A new characterization of narrow (weak) convergence of probability measures on Polish space is also obtained.

Approximation of invariant measures for a class of maps with indifferent fixed points [PDF]

open access: yes, 2005
Certain dynamical systems on the interval with neutrally stable repelling points admit invariant probability measures which are absolutely continuous with respect to Lebesgue measure.

Ontology‐Aligned Structuring and Reuse of Multimodal Materials Data and Workflows Toward Automatic Reproduction

open access: yesAdvanced Engineering Materials, EarlyView.
Reproduction of stacking fault energy calculations from literature with a semi‐automated large language model‐assisted extraction procedure: extraction of simulation protocol, atomistic structures, computational parameters, and reported results, ontology alignment, knowledge graph construction and, finally, recomputation forvalidation.

Equivalence of ensembles for two-species zero-range invariant measures [PDF]

open access: yes, 2008
We study the equivalence of ensembles for stationary measures of interacting particle systems with two conserved quantities and unbounded local state space.

Tightness of probability measures and its application in weak convergence. [PDF]

open access: yes
In stochastic theory, several types of convergence are known, with convergence in dis- tribution being among the most commonly used. This type of convergence is defined via weak convergence, which is the primary focus of this bachelor's thesis.

Designing Polymer Nanocomposites for X‐Ray Shielding: Mechanisms, Architectures, and Scalable Processing

open access: yesAdvanced Engineering Materials, EarlyView.
This review highlights advances in lightweight, lead‐free polymer nanocomposites for diagnostic X‐ray shielding. By linking filler chemistry, dispersion, architecture, and photon interaction mechanisms, it establishes structure–performance relationships guiding material design.

A Skorohod Representation Theorem for Uniform Distance [PDF]

open access: yes
Let µn be a probability measure on the Borel sigma-field on D[0, 1] with respect to Skorohod distance, n = 0. Necessary and sufficient conditions for the following statement are provided.

Maximal uniform convergence rates in parametric estimation problems [PDF]

open access: yes, 2008
This paper considers parametric estimation problems with independent, identically nonregularly distributed data. It focuses on rate efficiency, in the sense of maximal possible convergence rates of stochastically bounded estimators, as an optimality ...

On Equivalents of the Riemann Hypothesis Connected to the Approximation Properties of the Zeta Function

open access: yesAxioms
The famous Riemann hypothesis (RH) asserts that all non-trivial zeros of the Riemann zeta function ζ(s) (zeros different from s=−2m, m∈N) lie on the critical line σ=1/2.
