Comparison of a Miniaturized Implantable Two‐Stage Rotodynamic Blood Pump to Equivalent Single‐Stage Concepts

open access: yesArtificial Organs, EarlyView.
This study aims to evaluate the potential of a multistage pump design to enhance hemocompatibility in left ventricular assist devices. We found that the two‐stage concept offers favorable hemolysis measures compared to single‐stage designs, as the reduction in peak shear stresses outweighs the disadvantage associated with prolonged residence time ...

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

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

open access: yesBoreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

On the Unsteady Aerodynamic Forces and Flutter Characteristics of a T-tail

open access: yesJournal of the Japan Society for Aeronautical and Space Sciences, 1973
This paper presents a theory for calculating unsteady aerodynamic forces of a T-tail, of which the horizontal stabilizer is oscillating sinusoidally in a sideslipping or yawing mode. It is shown that numerical results are in good agreement with existing experimental results.

Real‐Time Rendering of Dynamic Line Sets using Voxel Ray Tracing

open access: yesComputer Graphics Forum, EarlyView.
Abstract Real‐time rendering of dynamic line sets is relevant in many visualization tasks, including unsteady flow visualization and interactive white matter reconstruction from Magnetic Resonance Imaging. High‐quality global illumination and transparency are important for conveying the spatial structure of dense line sets, yet remain difficult to ...

Air embolism secondary to suspected lymphatic tissue disruption with severe exercise‐induced pulmonary haemorrhage

open access: yesEquine Veterinary Education, EarlyView.
Summary Air embolism is rare in horses and typically associated with complications following intravenous catheterisation or other medical procedures. Exercise‐induced pulmonary haemorrhage (EIPH) is common in racehorses but not usually associated with air embolism. This report describes a case of air embolism in a 4‐year‐old Thoroughbred with EIPH. The

Gender‐Sensitive Nursing: An Operationalizing Concept Analysis

open access: yesJournal of Clinical Nursing, EarlyView.
ABSTRACT Introduction Gender biases in healthcare approaches lead to inequities in patient health outcomes, historically affecting women and gender minorities the most. In medicine, the concept of gender medicine explicitly addresses these disparities.

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

open access: yesSedimentology, EarlyView.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which
