Evolution of feedback loops in oscillatory systems

Feedback loops are major components of biochemical system. Many systems show multiple such (positive or negative) feedback loops. Nevertheless, very few quantitative analyses that address the question how such multiple feedback loops evolved. Based on publ ...

Robustness and evolution in oscillatory systems with feedback loops

Marc Hafner

Feedback loops are major components of biochemical systems. Many systems show multiple such (positive or negative) feedback loops. Nevertheless, very few quantitative analyses address the question how such multiple feedback loops evolved. Based on publishe ...

Organ Surface Markerless Tracking

Coralie Reissner

Today’s surgical navigation systems are difficult to use for deformable organs. State of the art technology struggles to continuously update and display preoperative information such that it corresponds to the actual position of the organ. An update method ...

Homogenization and long time asymptotic of a fluid-structure interaction problem

We study the homogenization of an unsteady fluid-structure interaction problem with a scaling corresponding to a long time asymptotic regime. We consider oscillating initial data which are Bloch wave packets corresponding to tubes vibrating in opposition o ...

Optimization of a new type of ultrasonic linear motor

Yves Perriard, José Fernandez Lopez

This paper presents the design, the properties, and the optimization study of a new type of ultrasonic linear motor. Numerical modeling has been carried out and simulations with software have been realized. To avoid performing a large number of simulations ...

Punching shear strength of reinforced concrete slabs without transverse reinforcement

Aurelio Muttoni

A mechanical explanation of the phenomenon of punching shear in slabs without transverse reinforcement is presented on the basis of the opening of a critical shear crack. It leads to the formulation of a new failure criterion for punching shear based on th ...

Kinematics and dynamic complexity of postural transitions in frail elderly subjects

Kamiar Aminian, Anisoara Ionescu, Arash Salarian, Raluca Lidia Ganea

The aim of this study was to propose a methodology allowing a detailed characterization of body sit-to-stand/stand-to-sit postural transition. Parameters characterizing the kinematics of the trunk movement during sit-to-stand (Si-St) postural transition we ...

Current profile tailoring using localized electron cyclotron heating in highly elongated TCV plasmas

Olivier Sauter, Stefano Coda, Timothy Goodman, Stefano Alberti, Patrick Blanchard, Laurie Porte, Antoine Pochelon, Yann Camenen, Andrea Scarabosio, Gilles Arnoux

Radially localized electron cyclotron heating (ECH) at the 2nd harmonic (X2) is used to tailor the current profile through the modification of the temperature, and hence conductivity, profiles. The optimal conditions for current profile broadening are inve ...

Fabrication and properties of high-Q AlN/SiO2 composite TFBAR's for above IC oscillators

Paul Muralt, Alvaro Artieda

High-Q, bulk acoustic wave composite resonators based on a symmetric layer sequence Of SiO2-A1N-SiO2 sandwiched between electrodes have been developed. Acoustic isolation was achieved by means of deep silicon etching to obtain membrane type TFBAR's. Three ...
