Robust Λ$\Lambda$‐Quantiles and Extremal Distributions

Mathematical Finance, EarlyView.
ABSTRACT In this paper, we investigate the robust models for Λ$\Lambda$‐quantiles with partial information regarding the loss distribution, where Λ$\Lambda$‐quantiles extend the classical quantiles by replacing the fixed probability level with a probability/loss function Λ$\Lambda$.

An Inverted Hermite Kolmogorov–Arnold Network Transformer for multi‐point settlement prediction in high‐speed railway bridge piers

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Settlement monitoring of high‐speed railway bridge piers (HSR‐BPs) is critical for ensuring construction and operational safety. However, existing methods for BP settlement prediction face three challenges: limited dataset size, inconsistent observation periods across measuring points, and difficulty in synchronizing spatiotemporal ...

On the Fourier transform of measures in Besov spaces

Bulletin of the London Mathematical Society, EarlyView.
Abstract We prove quantitative estimates for the decay of the Fourier transform of the Riesz potential of measures that are in homogeneous Besov spaces of the negative exponent: ∥Iαμ̂∥Lp,∞⩽C∥μ∥Mb12supt>0td−β2∥pt*μ∥∞12,$$\begin{align*} \Vert \widehat{I_{\alpha }\mu }\Vert _{L^{p, \infty }} \leqslant C \Vert \mu \Vert _{M_b}^{\frac{1}{2}}{\left(\sup _{t ...

Microstructure and hydration of interstitial in clinkers produced over molten steel

Journal of the American Ceramic Society, Volume 108, Issue 12, December 2025.
Abstract Scalable electrical production of clinker is possible under reducing conditions, and the reactivity of C3A produced in such conditions has only been superficially described. We examined electric clinkers made over molten steel with a range of fineness and compared them against commercial clinkers.

On the deep‐water and shallow‐water limits of the intermediate long wave equation from a statistical viewpoint

Transactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.
Abstract We study convergence problems for the intermediate long wave (ILW) equation, with the depth parameter δ>0$\delta > 0$, in the deep‐water limit (δ→∞$\delta \rightarrow \infty$) and the shallow‐water limit (δ→0$\delta \rightarrow 0$) from a statistical point of view.

Sonochemical activation for BaTiO3 synthesis: A rapid and efficient route to the tetragonal phase

International Journal of Applied Ceramic Technology, Volume 22, Issue 6, November/December 2025.
Abstract Barium titanate is a highly promising ferroelectric material, but its synthesis is often based on lengthy and complex processes. This paper presents the development of an ultrafast synthesis route for producing high‐purity tetragonal BaTiO3. The method combines a brief sonochemical activation (15 min) with conventional calcination. Compared to
