Assessing electron heat flux dropouts as signatures of magnetic field line disconnection from the Sun [PDF]

open access: yes, 2005
Suprathermal electrons focused along magnetic field lines, called the strahl, carry heat flux away from the Sun. Various factors can cause heat flux dropouts (HFDs), including times when the strahl almost vanishes.

DCT AND MLP IN THE APPLICATION OF MAGNETIC FLUX LEAKAGE DEFECT DETECTION

open access: yesActa Tecnología, 2020
Non-Destructive Testing (NDT) is known as a harmless technique for industrial pipeline cyclic inspection. This way tries to find out defected parts of a device used in industry with a test by means of non itself destroying. Many ways are known and employed in NDT procedure.

Research on magnetic flux leakage characteristics and identification methods under typical transformer winding defects

open access: yesZhejiang dianli
Current research lacks a comprehensive analysis of magnetic flux leakage patterns caused by transformer winding defects, which complicates defect detection.

Structure health monitoring of concrete structures using magnetic flux leakage [PDF]

open access: yes, 2022
Reinforcing bar, usually made of steel, is widely used in civil structures to increase the tensile strength of concrete. Heatinduced delayed expansion and corrosion expansion resulting in rust occupies a greater volume than rebar.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Research on Engineering Applications of Pipeline Stress Internal Detection Based on the Dual Excitation Magnetic Field

open access: yesShiyou jixie, 2023
Multiple methods,such as ultrasonic,radiographic and magnetic memory methods,can be used to measure the pipeline surface stress,and yet these methods are found with no application to pipeline online stress internal detection.Based on the structure of an ...

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network

open access: yesFEBS Letters, EarlyView.
Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Effective Modeling of Leakage Inductance for use in Circuit Simulation

open access: yes, 2008
Theoretical methods for the calculation of winding losses with respect to frequency have been well documented, but the variation in leakage inductance of magnetic components due to frequency has been less well addressed. In this paper Dowell’s well-known

Magnetic Flux Leakage Defect Detection Based on Deep Learning

open access: yesShiyou jixie, 2020
Traditional defect quantization of magnetic flux leakage lacks some components, and manual-extracted information is limited. This paper introduces a quantitative identification method based on deep learning and establishes a defect detection model for ...

Effects of the Remanent Magnetization on Detecting Signals in Magnetic Flux Leakage System

open access: yesJournal of the Korean Magnetics Society, 2005
The magnetic Hut leakage (MFL) type nondestructive testing (NDT) method is widely used to detect corrosion and defects, mechanical deformation of the underground gas pipelines. The object pipeline is magnetically saturated by the magnetic system with permanent magnet and yokes.
