Survival Analysis of Fatigue Lifetime in Aged Elastomers Using Weibull and Cox Regression Models

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 9, Page 3854-3873, September 2026.
ABSTRACT Fatigue tests conducted on elastomers inherently exhibit significant variability. Aging may induce stiffening and embrittlement, leading to premature failures outside the specimen gauge length and resulting in right‐censored data. Combined with the limited number of specimens, this leads to large uncertainties in fatigue lifetime estimation ...

A Conditional Tail Expectation Type Risk Measure for Time Series

Journal of Time Series Analysis, Volume 47, Issue 5, Page 967-983, September 2026.
ABSTRACT We consider the estimation of the conditional expectation 𝔼(Xh|X0>UX(1/p)), provided 𝔼|X0|<∞, at extreme levels, where (Xt)t∈ℤ$$ {\left({X}_t\right)}_{t\in \mathbb{Z}} $$ is a strictly stationary time series, UX$$ {U}_X $$ its tail quantile function, h$$ h $$ is a positive integer and p∈(0,1)$$ p\in \left(0,1\right) $$ is such that p→0$$ p\to ...

Volcanic Eruptions Reorganize Climate Teleconnections: Detection via Riemannian Covariance Fingerprinting

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Standard detection and attribution of volcanic forcing targets spatial temperature anomalies. We show that the covariance structure of climate variability carries an independent volcanic fingerprint. Applying tangent‐space regression on the symmetric positive definite manifold SPD(8) to 40 years of eight teleconnection indices, we detect ...

WEAKLY COMPACTLY GENERATED FRECHET SPACES

, 2014
. It is proved that a weakly compact generated Frechet space is LindelBf in the weak topology. As a corollary it is proved that for a finite measure space every weakly measurable function into a weakly compactly gener-ated Frechet space is weakly equ ...

Strict Frechet and generalized differentiability of the metric projection operator onto balls in Hilbert spaces

In this paper, we prove strict Frechet differentiability of the metric projection operator onto closed balls in Hilbert spaces, and we find exact expressions for Frechet derivatives.
