An estimation method of lightning-voltage sag severity based on adaptive association rule mining

Diance yu yibiao
Accurate estimation of voltage sag severity can provide a basis for sensitive users to adjust their production mode and avoid economic losses in advance. In view of lightning, which is the main cause of voltage sag, the widely deployed lightning location

Improved Space Vector Modulation of Quasi Z-Source Inverter to Suppress DC-Link Voltage Sag

IEEE Access, 2019
The three traditional strategies ZSVM1, ZSVM2, and ZSVM6 have been commonly used to control the quasi Z-source inverter (qZSI). However, there is a serious problem that the dc-link voltage of the qZSI drops under light load, leading to the distortion of ...

Diagnostic performance of neuroimaging modalities for epileptogenic focus localization: A systematic review

Epilepsia Open, EarlyView.
Abstract Objective Accurate localization of epileptogenic foci remains of significant importance for surgical planning in drug‐resistant epilepsy. Multiple neuroimaging modalities are available; however, their comparative diagnostic performance lacks comparative detailed synthesis.

An assessment of H‐bridge less grid‐tied multilevel inverter with minimum device count and lesser total standing voltage

IET Power Electronics, EarlyView., 2023
An innovative switched‐capacitor‐based inverter is proposed in this article. The suggested converter can produce a five‐level output voltage by utilizing minimal components (single dc source, six switches, and one capacitor). The effectiveness of the suggested inverter is verified by experimental results using hardware in loop OPAL‐RT OP4510.

Semiology in spontaneous versus cortical stimulation‐induced seizures during SEEG: A within‐patient comparison study

Epilepsia Open, EarlyView.
Abstract Objective We aimed to study the concordance of seizure semiology in direct electrical stimulation‐induced seizures (SIS) compared to spontaneous seizures during stereoelectroencephalography (SEEG) and to report on patient‐level variables associated with habitual and atypical SIS.

Early Response to an Integrated Family and Adolescent‐Focussed Treatment for Anorexia Nervosa and Atypical Anorexia Nervosa

European Eating Disorders Review, EarlyView.
ABSTRACT Objective Recovery rates for adolescent anorexia nervosa (AN) remain poor, requiring creativity within the field to explore alternative treatment options. One novel, evidence‐informed approach integrates both family/parent and individual adolescent‐focussed treatment components, through an individualised developmental lens. This study aimed to

Data‐Driven Dual‐Channel Dynamic Event‐Triggered Load Frequency Control for Multiarea Power Systems Under DoS Attacks

Energy Science &Engineering, EarlyView.
ABSTRACT System dynamics uncertainties and cyberattacks pose significant challenges to load frequency control in power systems. This paper presents a data‐driven load frequency control strategy for interconnected multi‐area power systems subject to denial‐of‐service attacks that disrupt both feedforward and feedback communication channels.

High‐Fidelity Simulation‐Driven Control Framework for Robust Grid Integration of Renewable Energy Systems

Energy Science &Engineering, EarlyView.
This work proposes a high‐fidelity, simulation‐driven control framework for robust grid integration of hybrid PV–wind systems using a modular, hierarchical multi‐loop architecture with adaptive decision logic. The framework coordinates power, DC‐link voltage, and grid currents under fast load and generation changes, enabling safe exploration of extreme

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

Environmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...
