A reduced computational and geometrical framework for inverse problems in haemodynamics

Alfio Quarteroni, Gianluigi Rozza, Andrea Manzoni, Toni Mikael Lassila

The solution of inverse problems in cardiovascular mathematics is computationally expensive. In this paper we apply a domain parametrization technique to reduce both the geometrical and computational complexity of the forward problem, and replace the finit ...

Spinal Subarachnoid Space Pressure Measurements in an In Vitro Spinal Stenosis Model: Implications on Syringomyelia Theories

Bryn Andrew Martin

Full explanation for the pathogenesis of syringomyelia (SM), a neuropathology characterized by the formation of a cystic cavity (syrinx) in the spinal cord (SC), has not yet been provided. It has been hypothesized that abnormal cerebrospinal fluid (CSF) pr ...

Complex Systems in Biomedicine

Alfio Quarteroni, Luca Formaggia

Mathematical modeling of human physiopathology is a tremendously ambitious task. It encompasses the modeling of most diverse compartments such as the cardiovascular, respiratory, skeletal and nervous systems, as well as the mechanical and biochemical inter ...

Multiscale modelling of the circulatory system: a preliminary analysis

Alfio Quarteroni, Fabio Nobile, Luca Formaggia

Shows how numerical solutions of the human cardiovascular system may be devised by coupling models having different physical dimensions. One of the aspects of the circulatory system is its multiscale nature. Local flow features may have a global effect on ...

Photodynamic therapy for 101 early cancers of the upper aerodigestive tract, the esophagus, and the bronchi: a single-institution experience

Hubert van den Bergh, Georges Wagnières, Alain Woodtli

Cancer, when detected at an early stage, has a very good probability of being eradicated by surgery or radiotherapy. However, less aggressive treatments also tend to provide high rates of cure without the side effects of radical therapy. We report on the r ...

On the wave transmission and reflection properties of stenoses

Nikolaos Stergiopoulos, Jean-Jacques Meister

This study is concerned with the wave reflection properties of arterial stenoses. Two theoretical models have been developed for deriving the reflection coefficient: a linear model resulting from the linearization of the pressure drop-flow equation and an ...

Computer simulation of arterial flow with applications to arterial and aortic stenoses

Nikolaos Stergiopoulos

A computer model for simulating pressure and flow propagation in the human arterial system is developed. The model is based on the one-dimensional flow equations and includes nonlinearities arising from geometry and material properties. Fifty-five arterial ...
