Physiological Control of Realheart Total Artificial Heart

open access: yesArtificial Organs, Volume 49, Issue 10, Page 1548-1557, October 2025.
This study evaluates the Realheart Total Artificial Heart's preload‐based physiological controller, which dynamically adjusts heart rate and stroke volume to mimic the heart's natural responses during sleep, rest, and exercise using a hybrid mock circulation loop of the cardiovascular system.

Linear perturbations of low angular momentum accretion flow in the Kerr metric and the corresponding emergent gravity phenomena

open access: yes, 2018
For certain geometric configuration of matter falling onto a rotating black hole, we develop a novel linear perturbation analysis scheme to perform the stability analysis of stationary integral accretion solutions corresponding to the steady state low ...

Warming strengthens food web effects of predator phenotypic variation

open access: yesFunctional Ecology, Volume 39, Issue 9, Page 2284-2299, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Intraspecific variation modifies ecological processes and ecosystem functioning. Still, we know relatively little of how the nature and strength of ecosystem effects caused by intraspecific variation may interact with climate change.

Accretion Disk Assembly During Common Envelope Evolution: Implications for Feedback and LIGO Binary Black Hole Formation

open access: yes, 2017
During a common envelope episode in a binary system, the engulfed companion spirals to tighter orbital separations under the influence of drag from the surrounding envelope material.

Very High Cycle Fatigue Performance of Ductile Cast Iron With Different Microstructures

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 9, Page 3950-3966, September 2025.
ABSTRACT The very high cycle fatigue performance of four ductile cast irons, a solid solution strengthened ferritic, ferritic‐pearlitic, and two austempered ductile cast irons, was investigated by ultrasonic fatigue testing under fully reversed loading conditions. The step‐stress fatigue testing method incorporating re‐use of runouts was employed, with

Separate Universe Simulations with IllustrisTNG: baryonic effects on power spectrum responses and higher-order statistics

open access: yes, 2019
We measure power spectrum response functions in the presence of baryonic physical processes using separate universe simulations with the IllustrisTNG galaxy formation model.

Hochdrucksynthese kristalliner doppelschichtiger Kohlenstoffnitrid‐Netzwerke stabilisiert in Bi7C10N18(N3(1‐x)O3x)

open access: yesAngewandte Chemie, Volume 137, Issue 35, August 25, 2025.
High‐pressure chemical reaction between Bi and various hydrogen‐free C‐N precursors induced by the infrared laser heating in a diamond anvil cell, leads to the formation of a compound Bi7C10N18(N3(1‐x)O3x), featuring double layers of poly‐N‐(1,3,5‐triazin‐2‐yl)‐guanidine [C4N6x‐]n and non‐polymerized guanidinate anions CN35‐.

The Tilt of the Fundamental Plane of Elliptical Galaxies: I. Dynamical and Structural Effects

open access: yes, 1996
In this paper we explore several structural and dynamical effects on the projected velocity dispersion as possible causes of the fundamental plane (FP) tilt of elliptical galaxies.

Acid Sulfate Soils and Their Pathways of Impact: A Swedish Case Study

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
This study is an initial report on the situation in an estuary affected by acidic sulfate soils in an area of Sweden where this has not been investigated before. The study clearly states that metals and acidic effluents from the agricultural acidic sulfate soil are transported via riverine water to the adjacent estuary where metals accumulate in the ...

Abrupt changes in alpha decay systematics as a manifestation of collective nuclear modes

open access: yes, 2010
An abrupt change in $\alpha$ decay systematics around the N=126 neutron shell closure is discussed. It is explained as a sudden hindrance of the clustering of the nucleons that eventually form the $\alpha$ particle. This is because the clustering induced
