Exploring the addition of Fe3O4 coated carbonyl iron powder to FeSi Soft magnetic composites: advantages and challenges

Materials & Design
Soft Magnetic Composites must be coated to protect against high core losses. This work studies coating iron powder with Fe3O4 in situ and using it in a two-powder system to enhance magnetic properties.

Acute Modafinil Exposure Induces Neurobehavioral Alterations in Zebrafish: Implications for Off‐Label Cognitive Enhancement

Journal of Applied Toxicology, EarlyView.
ABSTRACT Modafinil (2‐(benzhydrylsulfinyl)acetamide) is a psychostimulant commonly prescribed for sleep disorders such as narcolepsy, excessive daytime sleepiness, and obstructive sleep apnea. Recently, its use has extended beyond clinical indications, with neurotypical individuals adopting it as a smart drug to enhance alertness and cognitive ...

Development of Magnetization-Based Eddy Current Sensors for In-Line Inspection of X65 Pipelines

IEEE Access
Traditional in-line inspection (ILI) methods, such as magnetic flux leakage testing (MFLT) and eddy current testing (ECT), have inherent limitations. MFLT suffers from high magnetic attraction forces, which result in excessive friction and instability in

Diagnostic Accuracy of Shear Wave Elastography for the Assessment of Congestive Liver Disease in Patients With Structural Heart Disease

Journal of Clinical Ultrasound, EarlyView.
Shear wave elastography demonstrated moderate diagnostic accuracy for detecting congestive liver disease in patients with structural heart disease. Increased liver stiffness was associated with echocardiographic markers of venous congestion, supporting the concept that elastography may serve as a noninvasive marker of cardiohepatic interaction ...

MRI Diffusion Tensor Image Analysis Along the Perivascular Space: Effects of Mean Tract Orientation Divergence

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The diffusion tensor image analysis along the perivascular space (DTI‐ALPS) index is an established term, and ongoing research aims to explore underlying mechanisms. Hypothesis DTI‐ALPS measures are influenced by subject‐specific orientational differences of the projection and association fibers. Study Type Prospective.

MR Imaging‐Based Biomarkers for Strength Prediction: A Statistical Shape and Architecture Modeling of Quadriceps Muscles

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Muscle mass decline, associated with strength decline, is a hallmark of aging. Yet, strength decline greatly exceeds mass decline. This indicates that aspects of muscle quality and architecture—not reflected by mass—also influence force generating capacity.

Postprandial Changes in Thoracic Aortic Flow Detected by 4D Flow MRI May Influence Study Results

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background While there is a growing body of data using 4D flow MRI to distinguish between normal and abnormal blood flow values in the thoracic aorta, the extent of physiological variation or lack thereof is potentially undervalued. Physiological processes such as postprandial changes to hemodynamics might influence data, normal values, follow‐

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

Shiyou 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，
