Applications of Complex Uncertain Sequences via Lacunary Almost Statistical Convergence

Axioms
We explore the realm of uncertainty theory by investigating diverse notions of convergence and statistical convergence concerning complex uncertain sequences.

Design of a Multistable Finger Prosthesis with Programmable Metamaterials

Advanced Engineering Materials, EarlyView.
This research article shows the development of a multistable programmble metamaterial for the use as a finger prosthesis. The material was designed on different hierarchical levels where the influence of geometrical parameters and combination of mechanical elements was explored.

Mitigating Creep Anisotropy and Enhancing Performance in Additively Manufactured Ni‐Based Superalloys: A Review

Advanced Engineering Materials, EarlyView.
Additive manufacturing introduces pronounced microstructural and crystallographic anisotropy in Ni‐based superalloys, resulting in orientation‐dependent creep deformation and damage. This review identifies the key microstructural origins of creep anisotropy, examines their influence on dominant deformation mechanisms, and highlights processing ...

A Note on a Class of Estimates for the Regression Function

Sultan Qaboos University Journal for Science
In this paper we study the rate of convergence for a kernel general estimate of the regression function when the observed process is ρ ̃-mixing. The uniform almost sure convergence is obtained over a sequence of compact sets which increases to Rd as n →∞.

Convergence rate of principal component analysis with local-linear smoother for functional data under a unified weighing scheme

Statistical Theory and Related Fields, 2020
The unified weighing scheme for the local-linear smoother in analysing functional data can deal with data that are dense, sparse or of neither type. In this paper, we focus on the convergence rate of functional principal component analysis using this ...

On the almost sure convergence for sums of negatively superadditive dependent random vectors in Hilbert spaces and its application

, 2020
This paper develops almost sure convergence for sums of negatively superadditive dependent random vectors in Hilbert spaces, we obtain Chung type SLLN and the Jaite type SLLN for sequences of negatively superadditive dependent random vectors in Hilbert ...

Impact of Hydrogen Incorporation on Electronic and Magnetic Structure of X2CrNi18‐9 Stainless Steel

Advanced Engineering Materials, EarlyView.
Hydrogen uptake in austenitic stainless steel alters both its electronic and magnetic structure. Seebeck measurements reveal hydrogen‐induced shifts in the electronic density of states, while neutron scattering uncovers nanoscale inhomogeneities that grow upon hydrogen incorporation, with the most pronounced effect observed in the PBF as‐built state ...

On the convergence of moments in the almost sure central limit theorem for stochastic approximation algorithms [PDF]

, 2013
We study the almost sure asymptotic behaviour of stochastic approximation algorithms for the search of zero of a real function. The quadratic strong law of large numbers is extended to the powers greater than one.

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Maximal Inequalities for Dependent Random Variables and Applications

Journal of Inequalities and Applications, 2008
For a sequence {Xn,n≥1} of dependent square integrable random variables and a sequence {bn,n≥1} of positive numbers, we establish a maximal inequality for weighted sums of dependent random variables.
