On the impact of heterogeneity-aware mesh partitioning and non-contributing computation removal on parallel reservoir simulations

open access: yesJournal of Mathematics in Industry, 2021
Parallel computations have become standard practice for simulating the complicated multi-phase flow in a petroleum reservoir. Increasingly sophisticated numerical techniques have been developed in this context. During the chase of algorithmic superiority,

Computational models of ventricular mechanics and adaptation in response to right-ventricular pressure overload

open access: yesFrontiers in Physiology, 2022
Pulmonary arterial hypertension (PAH) is associated with substantial remodeling of the right ventricle (RV), which may at first be compensatory but at a later stage becomes detrimental to RV function and patient survival.

Generalized Parton Distributions in the Light-Front Constituent Quark Model

open access: yes, 2004
The Generalized Parton Distributions (GPDs) of the nucleon are analyzed within the relativistic constituent quark model formulated on the light-front. It is shown that the matrix elements of the plus component of the one-body vector current are plagued ...

Network recovery based on system crash early warning in a cascading failure model

open access: yesScientific Reports, 2018
This paper investigates the possibility of saving a network that is predicted to have a cascading failure that will eventually lead to a total collapse. We model cascading failures using the recently proposed KQ model.

Chiral properties of the constituent quark model [PDF]

open access: yes, 2006
We show that, in a model based exclusively on constituent-quark degrees of freedom interacting via a potential, the full axial current is conserved if the spectrum of \bar QQ states contains a massless pseudoscalar.

Human brain solute transport quantified by glymphatic MRI-informed biophysics during sleep and sleep deprivation

open access: yesFluids and Barriers of the CNS, 2023
Whether you are reading, running or sleeping, your brain and its fluid environment continuously interacts to distribute nutrients and clear metabolic waste.

Deriving the Bidomain Model of Cardiac Electrophysiology From a Cell-Based Model; Properties and Comparisons

open access: yesFrontiers in Physiology, 2022
The bidomain model is considered to be the gold standard for numerical simulation of the electrophysiology of cardiac tissue. The model provides important insights into the conduction properties of the electrochemical wave traversing the cardiac muscle ...

Vortex Mass in a Superfluid

open access: yes, 2018
We consider the inertial mass of a vortex in a superfluid. We obtain a vortex mass that is well defined and is determined microscopically and self-consistently by the elementary excitation energy of the kelvon quasiparticle localised within the vortex ...

Human intracranial pulsatility during the cardiac cycle: a computational modelling framework

open access: yesFluids and Barriers of the CNS, 2022
Background Today’s availability of medical imaging and computational resources set the scene for high-fidelity computational modelling of brain biomechanics. The brain and its environment feature a dynamic and complex interplay between the tissue, blood,
