Non-intrusive support of ground vehicle wind tunnel models through superconducting magnetic levitation [PDF]

open access: yes, 2006
Wind tunnel testing of racing cars is performed with a moving ground plane to take into account the downforce generated by the low ground clearance of these vehicles.

Investigation of the nonlinear dynamics of a diamagnetically levitating plate

open access: yes, 2021
Over the past decades the diamagnetic effect has been used for a variety of applications. This ranges from levitating a living frog to stabilizing a force sensor, designing an acceleration sensor and determin­ing the power of a laser.

Percutaneous Intervention in External Outflow Graft Obstruction of Magnetically Levitated Left Ventricular Assist Device: Long‐Term Follow‐Up and Quality of Life

open access: yesArtificial Organs, EarlyView.
eOGO is an uncommon adverse event in patients on long‐term LVAD support. Thirty‐one eOGO patients were identified in a single‐centre HM3 implantation program. Twenty patients underwent percutaneous stenting. This treatment resulted in immediate LVAD flow improvement and yielded satisfactory quality‐of‐life results, with 62.5% patients assigned a fair ...

A Tale of Magnets and Microphones: using a Magnetic Support and Balancing System (MSBS) for aeroacoustic wind tunnel testing

open access: yes, 2020
In acoustic wind tunnel testing, strut noise can be a great nuisance if it dominates the sound field. A magnetic model support would be a solution to this problem, as it supersedes the need for mechanical struts.

Device‐Induced Blood Damage in Pump‐Assisted Circulation: A Comparative Study of HeartMate III and BrioVAD Pumps

open access: yesArtificial Organs, EarlyView.
Shear‐induced blood damage—including hemolysis, platelet and neutrophil injury, and von Willebrand factor (vWF) degradation—was evaluated for the BrioVAD and HM3 using an in vitro circulatory loop under clinically relevant conditions. Across 15 biomarkers (n > 6 per group), no significant differences were observed between the two devices.

Space Vector Modulation for High Dynamic Current Control of a Self-Sensing Active Magnetic Bearing

open access: yes, 2021
The control loop of active magnetic bearings requires feedback of the rotor position to enable a stable levitation of the rotor. In contrast to conventional position sensor-based systems, self-sensing control can lead to a far more simple design of the ...

Shaping the Flow: Impact of Blade Shape on Performance and Hemocompatibility in Rotodynamic Blood Pumps

open access: yesArtificial Organs, EarlyView.
Blade shapes (leading‐edge geometry and thickness) in rotodynamic blood pumps were systematically evaluated. Thinner blades improve pump efficiency by reducing blockage effects, while neither blade thickness nor leading‐edge geometry shows clear hemocompatibility benefits. Overall, blade shape has a limited impact on hemocompatibility, indicating it is

EMS control system design for a Maglev vehicle - a critical system [PDF]

open access: yes, 1993
For the effective operation of a magnetically levitated (maglev) vehicle using electro-magnetic suspension, it is necessary that the airgap between the guideway and the levitating magnets is maintained.

Inflammation‐Regeneration Axis of Dental Pulp Stem Cells: Wnt/NF‐κB Crosstalk

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Background Inflammation critically determines dental pulp regenerative outcomes, with dental pulp stem cells (DPSCs) orchestrating tissue homeostasis through differentiation, self‐renewal and immunomodulation processes dynamically regulated by Wnt/β‐catenin and NF‐κB signaling crosstalk.
