Ca2+ dynamics in a population of smooth muscle cells: modeling the recruitment and synchronization

Jean-Jacques Meister, Roger Sauser, Jean-Louis Bény, Michèle Koenigsberger, Mathieu Lamboley

Many experimental studies have shown that arterial smooth muscle cells respond with cytosolic calcium rises to vasoconstrictor stimulation. A low vasoconstrictor concentration gives rise to asynchronous spikes in the calcium concentration in a few cells (a ...

Numerical modelling of Bi-2223 multifilamentary tapes with position-dependent Jc

Francesco Grilli, Bertrand Dutoit

Different measurement techniques have demonstrated that due to better alignment during the manufacturing process, the central filaments in multifilamentary Bi-2223 tapes have higher critical current density than the outer filaments. A numerical model of no ...

The "Liquid Computer": A Novel Strategy for Real-Time Computing on Time Series

Henry Markram

We will discuss in this survey article a new framework for analysing computations on time series and in particular on spike trains, introduced in (Maass et. al. 2002). In contrast to common computational models this new framework does not require that info ...

Magic and mysteries of modern molecular dynamics simulations: A basic introduction

Ursula Röthlisberger

A review. Since the first mol. dynamics simulations of hard spheres by Alder and Wainwright in the fifties of the last century (Alder, B.J. and Wainwright, T.E. (1957) Phase transition for a hard sphere system, J. Chem. Phys. 27, 1208-1209), this method ha ...

Cytosolic-free calcium in smooth-muscle and endothelial cells in an intact arterial wall from rat mesenteric artery in vitro

Nikolaos Stergiopoulos, Jean-Jacques Meister, Jean-Louis Bény, Alexander Schuster

The regulation of cytosolic-free calcium concentration of smooth-muscle and endothelial cells was mainly studied on cultured cells where the cross talk between these two coupled cell types is lost. In the present study, the cytosolic-free calcium concentra ...

Simultaneous arterial calcium dynamics and diameter measurements: application to myoendothelial communication

Nikolaos Stergiopoulos, Jean-Jacques Meister, Jean-Louis Bény, Alexander Schuster

The goal of the present study was to analyze the intercellular calcium communication between smooth muscle cells (SMCs) and endothelial cells (ECs) by simultaneously monitoring artery diameter and intracellular calcium concentration in a rat mesenteric art ...

Anatomic modeling of deformable human bodies

Daniel Thalmann

We propose a method to simulate human bodies based on anatomy concepts. We believe that the closer our model is to reality, the better our results will be. Using this approach, we are developing our human representation. Our model is divided into three lay ...

Gauge factor of thick-film resistors: Outcomes of the variable-range-hopping model

Peter Ryser, Claudio Grimaldi, Sigfrid Straessler

Despite a large amount of data and numerous theoretical proposals, the microscopic mechanism of ransport in thick-film resistors remains unclear. However, recent low-temperature measurements point toward a possible variable-range-hopping mechanism of trans ...

Real time muscle deformations using mass-spring systems

Daniel Thalmann

We propose a method to simulate muscle deformation in real-time, still aiming at satisfying visual results; that is, we are not attempting perfect simulation but building a useful tool for interactive applications. Muscles are represented at 2 levels: the ...

Robust FxLMS algorithms with improved convergence performance

Ali H. Sayed

This paper proposes two modifications of the filtered-x least mean squares (FxLMS) algorithm with improved convergence behavior albeit at the same computational cost of 2M operations per time step as the original FxLMS update. The paper further introduces ...
