Enhancement of the Remote Field Eddy Current Testing Performed from Outside of a Magnetic Tube

open access: yesAdvances in Electrical and Electronic Engineering, 2006
The paper deals with design of remote field eddy current probe for non-destructive testing dedicated for inspection of ferromagnetic tubular material from outside. The remote field effect inside the tube wall is achieved by the medium of a magnetic shield covering the probe.

Open diffusion magnetic resonance imaging and connectivity data for epilepsy and surgery: The IDEAS II release

open access: yesEpilepsia, EarlyView.
Abstract Objective Epileptic seizures are generated in cerebral networks that propagate ictal and interictal activity. The structure of cerebral networks underpinning epileptic activity can be inferred from diffusion‐weighted magnetic resonance imaging (DWI).

Glymphatic dysfunction couples with cortical excitation–inhibition imbalance in epilepsy: Evidence from Rasmussen encephalitis

open access: yesEpilepsia, EarlyView.
Cong Fu et al. demonstrate that glymphatic system dysfunction is linked to enhanced inhibitory cortical activity using diffusion MRI and EEG. These findings highlight a mechanistic link between perivascular fluid dynamics and neuronal activity, suggesting a role for glymphatic function in maintaining cortical stability in epilepsy.

A consensus roadmap for post‐traumatic epilepsy: Clinical biomarkers, research priorities, policy barriers, and pathways to interventional trials

open access: yesEpilepsia, EarlyView.
Abstract Understanding the mechanisms underlying post‐traumatic epilepsy (PTE) following traumatic brain injury (TBI), and developing strategies to prevent or modify its progression, has been the focus of large collaborative efforts within the epilepsy and TBI research communities for over a decade.

Detection and Identification of Pipeline Defects Based on Orthogonally Excited Multi-Parameter Sensing

open access: yesShiyou jixie
Complex morphologies, such as cracks, corrosion, and composite defects, are prone to develop in oil and gas pipelines during prolonged service. However, traditional differential eddy-current testing has limitations in corrosion morphology differentiation,

Cryostatless high temperature supercurrent bearings for rocket engine turbopumps [PDF]

open access: yes
The rocket engine systems examined include SSME, ALS, and CTV systems. The liquid hydrogen turbopumps in the SSME and ALS vehicle systems are identified as potentially attractive candidates for development of Supercurrent Bearings since the temperatures ...

Prediction of Pipeline Defect Depth and Classification Based on CatBoost

open access: yesEnergy Science &Engineering, EarlyView.
Obtaining detection data using in‐line pipeline inspection, the synthetic minority oversampling technique (SMOTE) is applied to expand the sample set, thereby increasing the number of minority‐class samples. This approach effectively improves minority‐class detection and enhances pipeline safety assessment. ABSTRACT Magnetic flux leakage detection is a

Multiobjective Optimization of Hydrogen‐Assisted Calophyllum inophyllum Biodiesel Operation in a Compression Ignition Engine

open access: yesEnergy Science &Engineering, EarlyView.
Tri‐fuel diesel–Calophyllum inophyllum biodiesel–hydrogen operation was tested over 96 points in a diesel engine. Eight performance and emission metrics feed a preference‐agnostic Bootstrapped Empirical Multiobjective Ranking and Selection methodology, revealing load‐blend‐hydrogen windows that increase efficiency, restrain smoke, and expose NOx trade ...

Dual process for improved recovery of essential oil and pectin from citrus waste

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Citrus essential oils (EO), particularly orange essential oil (OEO) and pectin, are high‐value chemical products widely used across various industries, including pharmaceuticals, food and beverages, detergents, and cosmetics. These compounds are present in the residual by‐products generated by juice production industries, and their ...
