Artificial stem cell niches

Stem cells are characterized by their dual ability to reproduce themselves (self-renew) and specialize (differentiate), yielding essentially unlimited numbers of daughter cells that can maintain and regenerate tissues. In contrast to their embryonic counte ...

Dividing Transactional Memories by Zero

Rachid Guerraoui, Michal Kapalka, Aleksandar Dragojevic

Software transactional memory (STM) is a promising technique for writing concurrent programs. So far, most STM approaches have been experimentally evaluated with small-scale microbenchmarks. In this paper, we present several surprising results from impleme ...

Comparison of mean flow similarity laws in zero pressure gradient turbulent boundary layers

Peter Monkewitz

The paper presents an in depth assessment of different similarity laws for the mean velocity profile in zero pressure gradient (ZPG) turbulent boundary layers (TBL's) in comparison with mostly experimental and few computational data. The emphasis is on the ...

Control of adult stem cell function by bioengineered artificial niches

Matthias Lütolf

Stem cells are characterized by their dual ability to self- renew and differentiate, yielding essentially unlimited numbers of progeny that can replenish tissues with either high turnover such as blood and skin or contribute to the regeneration of organs w ...

Spectrum and thermal fluctuations of a microcavity polariton Bose-Einstein condensate

Vincenzo Savona, Davide Sarchi

The Hartree-Fock-Popov theory of interacting Bose particles is developed, for modeling exciton-polaritons in semiconductor microcavities undergoing Bose-Einstein condensation. A self-consistent treatment of the linear exciton-photon coupling and of the exc ...

Global full-f gyrokinetic simulations of plasma turbulence

Laurent Villard, Alberto Bottino, Sébastien Jolliet, Paolo Angelino

Critical physical issues can be specifically tackled with the global full-f gyrokinetic code GYSELA. Three main results are presented. First, the self-consistent treatment of equilibrium and fluctuations highlights the competition between two compensation ...

Self-sensing methods to drive micro-machines

Yves Perriard, Omar Scaglione, Jan Persson

Synchronous motors require sensors in order to control these devices in speed and/or position. Basically, the auto-commutation needs 3 sensors for a 3-phase type actuator. In micro-motors, as there is no more room to place the sensors, self-sensing approac ...

Local Oxidation of Titanium Using Dynamic-Mode Tuning-Fork Probe with Microfabricated Silicon Cantilever

Nico de Rooij, Terunobu Akiyama, Kaspar Suter

We present a unique probe that is based on a quartz tuning fork and a microfabricated cantilever. The probe is self-actuating and self-sensing. The cantilever can be tailored to the needs of specific applications, in this case to feature an electrically co ...

Reaching Agreement with Unknown Participants in Mobile Self-Organized Networks in Spite of Process Crashes

André Schiper, David Cavin, Yoav Sasson

We consider the consensus problem in self-organized networks such as MANETs. Consensus oﬀers a means for reliably solving agreement related problems, which in a self-organized setting can help bring enhanced structure and reliability to the highly dynamic ...

Onset of coherent photoluminescence in semiconductor microcavities

Vincenzo Savona, Paolo Schwendimann

The nonlinear dynamics of exciton-polaritons in semiconductor microcavities is treated within a model of interacting bosons for the signal, pump, and idler modes. The correlations between all three polariton modes are taken into account in the lowest order ...
