State of health estimation for all-vanadium redox flow batteries based on interaction measurement analysis and genetic algorithm
Published on 2026-10-24 by @OXFORD
Abstract: AbstractAccurate state of health (SOH) estimation of all-vanadium redox flow batteries (VRFBs) is essential for ensuring safe and reliable operation. In this paper, a series of VRFB charge/discharge cycle experiments is conducted to extract the best health feature subset by the interaction measurement analysis, based on which an SOH estimation method combining the extreme learning machine and a genetic algorithm (GA) is proposed. Compared with the sand cat swarm optimization algorithm, GAs are m[...]
Our summary: The study presents a method for estimating the state of health (SOH) of all-vanadium redox flow batteries using interaction measurement analysis and a genetic algorithm. It demonstrates superior accuracy in SOH prediction compared to other optimization methods, achieving a maximum error of 0.53%. The proposed approach is robust against noisy conditions and suitable for various data acquisition levels, enhancing operational reliability in industrial applications.

Iterative delay correction improves breath-hold cerebrovascular reactivity mapping in clinical populations
Published on 2026-10-01 by @MIT
Abstract: AbstractCerebrovascular reactivity (CVR), the ability of cerebral blood vessels to dilate or constrict in response to a vasoactive stimulus, is an important measure of cerebrovascular health. Accurate CVR estimation requires accounting for the time required for the vasoactive stimulus to reach each brain region and the time it takes for local arterioles to modulate cerebral blood flow. The temporal search range used to calculate this spatially varying offset can substantially impact CVR estimate[...]
Our summary: An iterative approach for determining maximum shift improves cerebrovascular reactivity (CVR) mapping in stroke survivors. This method increases the number of voxels with significant CVR and alters CVR polarity in certain cases. The findings indicate that iterative delay correction enhances CVR assessments in clinical populations.
