Stretch-elicited calcium responses in the intact mouse thoracic aorta

Stretch-elicited intracellular calcium (Ca(2+)) changes in individual smooth muscle cells in a ring of aorta were measured simultaneously with the force developed by the ring. A phasic increase in Ca(2+) was observed in 30% of the cells and a sus ...

Calcium dynamics and intercellular communication in arterial smooth muscle cells

Mathieu Lamboley

This thesis is a contribution to the field of cellular communication in arteries during vasomotion, i.e. rhythmic and spontaneous diameter oscillations of arteries. Investigating how individual smooth muscle cells (SMCs) and endothelial cells (ECs) calcium ...

On the universality of Burnashev's error exponent

Emre Telatar, Aslan Tchamkerten

We consider communication over a time invariant discrete memoryless channel with noiseless and instantaneous feedback. We assume that the communicating parties are not aware of the underlying channel, however they know that it belongs to some specific fami ...

Feedback communication over unknown channels

Aslan Tchamkerten

Suppose Q is a family of discrete memoryless channels. An unknown member of Q will be available, with perfect, causal output feedback for communication. Is there a coding scheme (possibly with variable transmission time) that can achieve the Burnashev erro ...

Semantic Virtual Environments with Adaptive Multimodal Interfaces

Daniel Thalmann, Frédéric Vexo

We present a system for real-time configuration of multimodal interfaces to Virtual Environments (VE). The flexibility of our tool is supported by a semantics-based representation of VEs. Semantic descriptors are used to define interaction devices and virt ...

The Optimal MAC Layer for Low Power UWB Networks is With Independent Channels and No Power Control

Jean-Yves Le Boudec

We are interested in the design of a MAC layer for systems that use ultra-wide band (UWB) communication and transmit very little power. We first explore the design space and find, that, for such networks, the optimal MAC should allow concurrent transmissio ...

Calcium dynamics and vasomotion in rat mesenteric arteries

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

Smooth muscle cell calcium dynamics and diameter were measured in intact pressurized rat mesenteric artery segments during vasoconstriction and vasomotion. Arteries showed a certain norepinephrine (NE) threshold (0.3-0.4 microM) for the onset of vasomotion ...

Polyelectrolyte-modified short microchannel for cation separation

Hubert Girault, Christophe Roussel, Xiaoxia Bai

Three alkali cations, potassium, sodium, and lithium, have been separated within 15 s in a 1 cm long polymer microchip. The separation microchannel is modified by a polycation, poly(allylammonium chloride), which makes the channel surfaces positively charg ...

Optimal feedback schemes over unknown channels

Emre Telatar

Communication over unknown discrete memoryless channels with instantaneous and perfect feedback is considered. For a given set of channels we define a notion of optimal coding schemes in terms of achievable rate and error exponent, and prove the existence ...
