Advances in ZNN Models for Solving Time-Varying Sylvester Equations: Convergence, Robustness, and Applications

open access: yesIEEE Access
This article provides a systematic review of the specific field of solving time-varying Sylvester equations using zeroing neural network (ZNN), and delves into multi parameter joint sensitivity analysis and design strategies for the first time.

A timing problem for instrumental convergence

open access: yesPhilosophical Studies
Abstract Those who worry about a superintelligent AI destroying humanity often appeal to the instrumental convergence thesis—the claim that even if we don’t know what a superintelligence’s ultimate goals will be, we can expect it to pursue various instrumental goals which are useful for achieving most ends. In this paper, we argue that one of

A Positron Lifetime Study of Cooling and Natural Aging of Solutionized Aluminum Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
The process during cooling of Al–Mg and Al–Mg–Si alloys from the solutionizing temperature down to 20 °C is interrupted. These states are analyzed with positron lifetime spectroscopy to trace the processes during cooling. In different temperature ranges, two stages of vacancy loss and solute clustering are identified.

Uniform Lacunary Statistical Convergence on Time Scales

open access: yesInternational Journal of Analysis and Applications, 2017
We introduce (θ,m)-uniform lacunary density of any set and (θ,m)-uniform lacunary statistical convergence on an arbitrary time scale. Moreover, (θ,m)-uniform strongly p-lacunary summability and some inclusion relations about these new concepts are also ...

Enhanced Oxidation and Thermal Shock Resistance of N‐type Mg2Si0.89(Sn0.1,Sb0.01) Thermoelectric Material via Cr0.9Si0.1 Coating

open access: yesAdvanced Engineering Materials, EarlyView.
Cr0.9Si0.1 protective coatings are developed to enhance the thermal‐shock and oxidation resistance of Mg2Si0.89(Sn0.1,Sb0.01) thermoelectric (TE) materials. The coating forms a dense and adherent barrier that suppresses oxygen diffusion and mitigates mechanical degradation during cyclic oxidation, demonstrating its potential to improve the long‐term ...

High‐Entropy Alloy Design Toward Cobalt Substitution for High Hardness and Low Wear Rate Using X–Cr–Fe–Mn–Ni System

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the replacement of cobalt using the high‐entropy alloy design strategy for wear‐resistant components operating at high temperatures. Starting from the Cantor alloy, cobalt is substituted with Cu, Al, V, or Mo. Metallurgical and tribological analyses reveal that aluminum, vanadium, and molybdenum effectively strengthen the developed ...

Stabilized Intermediate Phase Via Pseudo‐Halide Anions Toward Highly Efficient and Light‐Soaking Stable Perovskite Solar Cells

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The formate pseudo‐halide anion is strategically introduced at the buried interface to stabilize the intermediate phases formed during perovskite crystallization. The controlled crystallization enhances crystallinity and alleviates tensile strain, eliminating residual PbI2 near the buried interface.
