Simple technique for superconducting joints quality estimation in bulk melt-processed high temperature superconductors [PDF]

open access: yes, 2001
We propose an empirical approach to estimate the quality of superconducting joints (welds) between blocks of bulk high temperature superconductors (HTS).

Predictors of Brain Infarction in Pediatric Patients During Extracorporeal Membrane Oxygenation

open access: yesArtificial Organs, EarlyView.
In 179 pediatric ECMO patients, brain infarction (BI) occurred in 28% and was linked to markedly higher 30‐day mortality. VA ECMO mode (vs. VV) and higher pre‐ECMO arterial lactate independently predicted BI, supporting standardized neuro‐monitoring and liberal early brain CT, especially for children on VA ECMO.

Robust controller design for single axis magnetic levitation system. [PDF]

open access: yes, 2010
This paper demonstrates theoretically the main idea of magnetic force control in magnetic levitation system using flux density measurements. A Hall-effect sensor is used to sense the flux density in the air gap.

Cooling the Motion of Diamond Nanocrystals in a Magneto-Gravitational Trap in High Vacuum

open access: yes, 2016
Levitated diamond nanocrystals with nitrogen-vacancy (NV) centres in high vacuum have been proposed as a unique system for experiments in fundamental quantum mechanics, including the generation of large quantum superposition states and tests of quantum ...

Efficient fuzzy logic controller for magnetic levitation systems

open access: yesNigerian Journal of Technological Development, 2017
Magnetic levitation is a system of suspending a body or a complete system against gravity. Suspending a system in air against gravity without using fixed structure for supporting is highly unstable and complex. In the previous research many  techniques of stabilizing magnetic levitation systems were discussed.

Effect of Worm‐Like Amorphous Phase on Corrosion Resistance and Antibacterial Properties of NiTiCu Alloy

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT By adding CuO, the worm‐like amorphous phase and atomic clusters were simultaneously introduced, enabling the (Ni40Ti40Cu20)99.9O0.1 alloy micron columns to exhibit a uniform flow strain of over 40% and a strength of over 2.5 GPa during compression.
