MATHICSE Technical Report : A complex blood flow patterns in an idealized left ventricle: a numerical study
Alfio Quarteroni, Luca Dede', Anna Tagliabue
In this paper, we study the blood flow dynamics in a three-dimensional (3D) idealized left ventricle of the human heart whose deformation is driven by muscle contraction and relaxation in coordination with the action of the mitral and aortic valves. We pro ...
MATHICSE2017Jointly Learning Energy Expenditures and Activities using Egocentric Multimodal Signals
Physiological signals such as heart rate can provide valuable information about an individual’s state and activity. However, existing work on computer vision has not yet explored leveraging these signals to enhance egocentric video understanding. In this w ...
2017Sampling and Exact Reconstruction of Pulses with Variable Width
Martin Vetterli, Adam James Scholefield, Loïc Arnaud Baboulaz, Gilles Baechler
Recent sampling results enable the reconstruction of signals composed of streams of fixed-shaped pulses. These results have found applications in topics as varied as channel estimation, biomedical imaging and radio astronomy. However, in many real signals, ...
Institute of Electrical and Electronics Engineers2017Measuring coral calcification under ocean acidification: methodological considerations for the 45Ca-uptake and total alkalinity anomaly technique
Thomas Krüger, Maoz Fine, Stéphanie Kéren Cohen
As the oceans become less alkaline due to rising CO2 levels, deleterious consequences are expected for calcifying corals. Predicting how coral calcification will be affected by on-going ocean acidification (OA) requires an accurate assessment of CaCO3 depo ...
Peerj Inc2017A coupled 3D-1D numerical monodomain solver for cardiac electrical activation in the myocardium with detailed Purkinje network
Alfio Quarteroni, Christian Vergara, Toni Mikael Lassila
We present a model for the electrophysiology in the heart to handle the electrical propagation through the Purkinje system and in the myocardium, with two-way coupling at the Purkinje-muscle junctions. In both the subproblems the monodomain model is consid ...
Elsevier2016MATHICSE Technical Report : Integrated Heart – Coupling multiscale and multiphysics models for the simulation of the cardiac function
Alfio Quarteroni, Ricardo Esteban Ruiz Baier, Toni Mikael Lassila, Simone Rossi
Mathematical modelling of the human heart and its function can expand our understanding of various cardiac diseases, which remain the most common cause of death in the developed world. Like other physiological systems, the heart can be understood as a comp ...
MATHICSE2016Observer Placement for Source Localization: the Effect of Budgets and Transmission Variance
Patrick Thiran, Laura Elisa Celis, Brunella Marta Spinelli
When an epidemic spreads in a network, a key question is where was its source, i.e., the node that started the epidemic. If we know the time at which various nodes were infected, we can attempt to use this information in order to identify the source. Howev ...
2016Extraction of QRS fiducial points from the ECG using adaptive mathematical morphology
Jean-Marc Vesin, Sasan Yazdani
QRS complex detection in the electrocardiogram (ECG) has been extensively investigated over the last two decades. Still, some issues remain pending due to the diversity of QRS complex shapes and various perturbations, notably baseline drift. This is especi ...
Academic Press Inc Elsevier Science2016Prediction of Atrial Fibrillation Termination by Catheter Ablation Using Adaptive Frequency Tracking of Atrial ECG Signal
Jean-Marc Vesin, Adrian Luca, Andréa Buttu, Etienne Pruvot
Our study aims at determining whether the efficiency of step-wise catheter ablation (step-CA) of persistent atrial fibrillation (pAF) can be tracked using organization indices based on the harmonic components of atrial ECG signals until pAF termination. EC ...
2016Glutathione deficit affects the integrity and function of the fimbria/fornix and anterior commissure in mice: relevance for schizophrenia
Rolf Gruetter, Yohan Van de Looij, Aline Monin, João Miguel das Neves Duarte, Kim Do, Alberto Corcoba
BACKGROUND: Structural anomalies of white matter (WM) are found in various brain regions of patients with schizophrenia, bipolar and other psychiatric disorders, but the causes at cellular and molecular levels remain unclear. Oxidative stress and redox dys ...
