Standardization of In Vitro Evaluation of Extracorporeal Life Support (ECLS) Devices for Research and Development

Artificial Organs, EarlyView.
ABSTRACT Extracorporeal life support (ECLS) technology has witnessed remarkable advancements during the last decades. However, further research and development of devices are required to increase, for example, performance‐efficiency, hemocompatibility, and long‐term stability.

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

Boreas, 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.

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

Equine 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

Unsteady aerodynamics of an oscillating cascade in a compressible flow field [PDF]

Fundamental experiments were performed in the NASA Lewis Transonic Oscillating Cascade Facility to investigate and quantify the unsteady aerodynamics of a cascade of biconvex airfoils executing torsion-mode oscillations at realistic reduced frequencies ...

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

Sedimentology, 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

Neuromuscular fatigue and loss of torque complexity during severe‐intensity exercise: The role of muscle size

Experimental Physiology, EarlyView.
Abstract This study investigated the effect of severe‐intensity exercise on neuromuscular fatigue (NMF) and torque complexity in two muscle groups of different sizes. The NMF of 11 healthy males was assessed through maximal voluntary contractions at the beginning, every minute and at task failure during intermittent isometric exercise performed at an ...

CFD‐Based and Control‐Oriented Modeling of a Counterflow Heat Exchanger With Utilization of Parameter Identification

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Counterflow heat exchangers (CHXs) thermally couple consumers and producers to a district heating network (DHN). Fluctuating loads and control actions naturally lead to unsteady operation conditions of the network and its components, posing a challenge for DHN models and CHX parameterizations based on Nusselt correlations that assume steady ...

Stereoscopic Serpentine Channel‐Based Cold Plate Design for Enhanced Liquid Cooling of EV Batteries

Battery Energy, Volume 5, Issue 3, May 2026.
The Graphical Abstract shows a 16‐cell battery pack used in the numerical study, along with temperature contours on the surface of coolant flow channels and a transient average surface temperature plot. A serpentine base plate and a stereoscopic serpentine cold plate are investigated, and the results are compared.
