Experimental investigation of the effects of neon injection in TCV

Basil Duval, Yves Martin, Jean-Marc Moret, Ivo Furno, Henri Weisen, Jonathan Bryan Lister, Richard Pitts

This contribution describes the results of impurity seeding experiments using neon gas injection into the private fl zone of an ohmically heated TCV single null lower, deuterium fuelled, open divertor configuration. In these first experiments, neon has bee ...

Femtosecond dynamics of secondary radiation formation from quantum well excitons

Benoît Marie Joseph Deveaud

The time-resolved secondary emission of resonantly created excitons in GaAs quantum wells is studied using femtosecond up-conversion spectroscopy. The behaviour of the rise and decay of the secondary emission and reflectivity in quantum welts is strongly d ...

Resonant Rayleigh scattering versus incoherent luminescence in semiconductor microcavities

Romuald Houdré, Benoît Marie Joseph Deveaud, Ursula Oesterle

It is demonstrated that during the first few picoseconds after resonant femtosecond excitation the secondary radiation from a strongly coupled semiconductor microcavity containing one quantum well is dominated by Rayleigh scattered light. At early times af ...

Interstitial photodynamic therapy with tetra(m-hydroxyphenyl)chlorin: tumor versus striated muscle damage

Hubert van den Bergh, Georges Wagnières, Alain Woodtli

Purpose: The present study was initiated to det. the conditions under which a single photodynamic treatment would induce maximal damage to a tumor with no or at least minimal reversible damage to a normal striated muscle. Methods and Materials: The techniq ...

Mutation of yeast Ku genes disrupts the subnuclear organization of telomeres

Thierry Laroche

The mammalian Ku70 and Ku86 proteins form a heterodimer that binds to the ends of double-stranded DNA in vitro and is required for repair of radiation-induced strand breaks and V(D)J recombination [1,2]. Deletion of the Saccharomyces cerevisiae genes HDF1 ...

Resonant femtosecond emission from quantum well excitons: The role of Rayleigh scattering and luminescence

Benoît Marie Joseph Deveaud

We study the ultrafast properties of secondary radiation of semiconductor quantum wells under resonant excitation. We show that the exciton density dependence allows one to identify the origin of secondary radiation. At high exciton densities, the emission ...

Kinetic modeling of scrape-off layer plasmas

Olivier Sauter

Electron transport along open field lines in the diverted scrape-off layer of a tokamak is studied numerically via a kinetic Fokker-Planck approach. The method allows calculation of the distribution function in a situation where large parallel temperature ...

Kinetics of glucose delivery to subcutaneous tissue in rats measured with 0.3-mm amperometric microsensors

Jeffrey Alan Hubbell

The time between i.v. injection of a glucose bolus and the time the glucose concn. peaked in the s.c. tissue was measured in pentobarbital-anesthetized rats with implanted 290-mm-diam. amperometric sensors. Boluses of 100, 200, and 400 mg/kg body wt. were ...
