A tree code for planetesimal dynamics: Comparison with a hybrid direct code [PDF]

open access: yes, 2003
We present a tree code for simulations of collisional systems dominated by a central mass. We describe the implementation of the code and the results of some test runs with which the performance of the code was tested.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Increasing the Glen–Nye Power‐Law Exponent Accelerates Ice‐Loss Projections for the Amundsen Sea Embayment, West Antarctica

open access: yesGeophysical Research Letters
AbstractGlacier flow is typically modeled using a power‐law rheology known as the Glen–Nye flow law, with the power assumed to be 3. However, recent research and past observations suggest that may better represent ice flow in some locations. We lack a quantitative understanding of how much affects ice‐loss projections, and its significance relative ...

The Impact of Tilburg Frailty on Poststroke Fatigue in First‐Ever Stroke Patients: A Cross‐Sectional Study With Unified Measurement Tools and Improved Statistics

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Poststroke fatigue (PSF) and frailty share substantial overlap in their manifestations, yet previous research has yielded conflicting results due to the use of heterogeneous frailty assessment tools. Objective To evaluate the independent impact of frailty on PSF using a unified measurement system (Tilburg Frailty Indicator, TFI ...

Amplitude and Temporal Dynamics of Motion Sickness

open access: yesFrontiers in Systems Neuroscience, 2022
The relationship between the amplitude of motion and the accumulation of motion sickness in time is unclear. Here, we investigated this relationship at the individual and group level. Seventeen participants were exposed to four oscillatory motion stimuli,

The baryonic self similarity of dark matter

open access: yes, 2014
The cosmological simulations indicates that the dark matter haloes have specific self similar properties. However the halo similarity is affected by the baryonic feedback, the momentum injected by the supernovae re-shape the dark matter core and ...

Identifying High‐Impact Solutions to Address Racial and Ethnic Health Disparities in Lupus: A Consensus‐Based Approach

open access: yesArthritis Care &Research, EarlyView.
Objective We conducted formative research aimed at identifying solutions that address inequitable health outcomes in lupus due to adverse social determinants of health (SDoH). Methods We conducted a search for keywords, which provided insights into potential solutions and initiatives underway. An advisory panel of lupus experts iteratively reviewed the

Interaction of an Acceleration Wave with a Strong Shock in Transient Pinched Plasma

open access: yesJournal of Applied Fluid Mechanics, 2016
In this paper, the evolution of an acceleration wave for the system of partial differential equations describing one dimensional, unsteady, axisymmetric motion of transient pinched plasma has been considered.

Barrow holographic dark energy with varying exponent

open access: yesNuclear Physics B
We construct Barrow holographic dark energy with varying exponent. Such an energy-scale-dependent behavior is typical in quantum field theory and quantum gravity under renormalization group considerations, however in the present scenario it has an ...
