Enabling unstructured-mesh computation on massively tiled AI processors: An example of accelerating in silico cardiac simulation

open access: yesFrontiers in Physics, 2023
A new trend in processor architecture design is the packaging of thousands of small processor cores into a single device, where there is no device-level shared memory but each core has its own local memory.

Mathematical Models of Cardiac Pacemaking Function

open access: yesFrontiers in Physics, 2013
Over the past half century, there has been intense and fruitful interaction between experimental and computational investigations of cardiac function. This interaction has, for example, led to deep understanding of cardiac excitation-contraction coupling;

Efficient Numerical Solution of the EMI Model Representing the Extracellular Space (E), Cell Membrane (M) and Intracellular Space (I) of a Collection of Cardiac Cells

open access: yesFrontiers in Physics, 2021
The EMI model represents excitable cells in a more accurate manner than traditional homogenized models at the price of increased computational complexity.

Automated landmarking of bends in vascular structures: a comparative study with application to the internal carotid artery

open access: yesBioMedical Engineering OnLine, 2021
Automated tools for landmarking the internal carotid artery (ICA) bends have the potential for efficient and objective medical image-based morphometric analysis. The two existing algorithms rely on numerical approximations of curvature and torsion of the

Leading and higher twists in proton, neutron and deuteron unpolarized structure functions [PDF]

open access: yes, 2006
We summarize the results of a recent global analysis of proton and deuteron F2 structure function world data performed over a large range of kinematics, including recent measurements done at JLab with the CLAS detector. From these data the lowest moments

Isgur-Wise form factors of heavy baryons within a light-front constituent quark model [PDF]

open access: yes, 1997
The space-like elastic form factors of baryons containing a heavy quark are investigated within a light-front constituent quark model in the limit of infinite heavy-quark mass, adopting a gaussian-like ansatz for the three-quark wave function.

Backtrack Programming with SIMULA [PDF]

open access: yesThe Computer Journal, 1984
Summary: Backtrack programming is a technique which has been built into a number of languages, either by defining new primitives or by extension, for the solution of problems of a combinatorial nature. An extension of SIMULA is described, from the user's point of view, which allows all the existing features but also includes facilities for backtrack ...

Nanoscale Curvature Regulates YAP/TAZ Nuclear Localization Through Nuclear Deformation and Rupture. [PDF]

open access: yesAdv Sci (Weinh)
This study uses experiments and biophysical modeling to examine the response and adaptation of cells to nanoscale topography of surfaces. It is shown that cytoskeletal assembly and nuclear localization of transcription regulatory factors such as yes‐associated protein (YAP) and transcriptional coactivator with PDZ‐binding motif (TAZ) can be tuned by ...
