Bayesian imputation of COVID-19 positive test counts for nowcasting under reporting lag
Radka Jersakova, James Lomax, James Hetherington +4
Obtaining up to date information on the number of UK COVID-19 regional infections is hampered by the reporting lag in positive test results for people with COVID-19 symptoms. In th…
Magritte, a modern software library for 3D radiative transfer: II. Adaptive ray-tracing, mesh construction and reduction
Frederik De Ceuster, Jan Bolte, Ward Homan +6
Radiative transfer is a notoriously difficult and computationally demanding problem. Yet, it is an indispensable ingredient in nearly all astrophysical and cosmological simulations…
Magritte, a modern software library for 3D radiative transfer: I. Non-LTE atomic and molecular line modelling
Frederik De Ceuster, Ward Homan, Jeremy Yates +3
Radiative transfer is a key component in almost all astrophysical and cosmological simulations. We present Magritte: a modern open-source software library for 3D radiative transfer…
Design choices for productive, secure, data-intensive research at scale in the cloud
Diego Arenas, Jon Atkins, Claire Austin +22
We present a policy and process framework for secure environments for productive data science research projects at scale, by combining prevailing data security threat and risk prof…
Assessing Simulations of Imperial Dynamics and Conflict in the Ancient World
Jim Madge, Giovanni Colavizza, James Hetherington +2
The development of models to capture large-scale dynamics in human history is one of the core contributions of cliodynamics. Most often, these models are assessed by their predicti…
Report on the Third Workshop on Sustainable Software for Science: Practice and Experiences (WSSSPE3)
Daniel S. Katz, Sou-Cheng T. Choi, Kyle E. Niemeyer +18
This report records and discusses the Third Workshop on Sustainable Software for Science: Practice and Experiences (WSSSPE3). The report includes a description of the keynote prese…
FabSim: facilitating computational research through automation on large-scale and distributed e-infrastructures
Derek Groen, Agastya Bhati, James Suter +3
We present FabSim, a toolkit developed to simplify a range of computational tasks for researchers in diverse disciplines. FabSim is flexible, adaptable, and allows users to perform…
An automated multiscale ensemble simulation approach for vascular blood flow
Mohamed A. Itani, Ulf D. Schiller, Sebastian Schmieschek +6
Cerebrovascular diseases such as brain aneurysms are a primary cause of adult disability. The flow dynamics in brain arteries, both during periods of rest and increased activity, a…
Computer simulations reveal complex distribution of haemodynamic forces in a mouse retina model of angiogenesis
Miguel O. Bernabeu, Martin Jones, Jens H. Nielsen +8
There is currently limited understanding of the role played by haemodynamic forces on the processes governing vascular development. One of many obstacles to be overcome is being ab…
Impact of blood rheology on wall shear stress in a model of the middle cerebral artery
Miguel O. Bernabeu, Rupert W. Nash, Derek Groen +4
Perturbations to the homeostatic distribution of mechanical forces exerted by blood on the endothelial layer have been correlated with vascular pathologies including intracranial a…
Choice of boundary condition for lattice-Boltzmann simulation of moderate Reynolds number flow in complex domains
Rupert W. Nash, Hywel B. Carver, Miguel O. Bernabeu +4
Modeling blood flow in larger vessels using lattice-Boltzmann methods comes with a challenging set of constraints: a complex geometry with walls and inlet/outlets at arbitrary orie…
Coalesced communication: a design pattern for complex parallel scientific software
Hywel B. Carver, Derek Groen, James Hetherington +3
We present a new design pattern for high-performance parallel scientific software, named coalesced communication. This pattern allows for a structured way to improve the communicat…
Analyzing and Modeling the Performance of the HemeLB Lattice-Boltzmann Simulation Environment
Derek Groen, James Hetherington, Hywel B. Carver +3
We investigate the performance of the HemeLB lattice-Boltzmann simulator for cerebrovascular blood flow, aimed at providing timely and clinically relevant assistance to neurosurgeo…
