Opt Express. 2013 Jun 03;21(11):13219-27. doi: 10.1364/OE.21.013219.

Advanced modulation formats call for suitable IQ modulators. Using the silicon-on-insulator (SOI) platform we exploit the linear electro-optic effect by functionalizing a photonic integrated circuit with an organic χ(2)-nonlinear cladding. We demonstrate that this silicon-organic hybrid (SOH) technology allows...

Opt Express. 2013 Jun 03;21(11):13293-304. doi: 10.1364/OE.21.013293.

A compact micro-optical interferometer is presented that combines two optical 90° hybrids or, alternatively, four delay interferometers into one interferometer structure sharing one tunable delay line. The interferometer can function as a frontend of either a coherent receiver or...

Neuropsychiatr Dis Treat. 2014 Aug 07;10:1459-68. doi: 10.2147/NDT.S63090. eCollection 2014.

BACKGROUND: The current study examined the psychometric properties of the 12-item French-language version of the Questionnaire on Smoking Urges (QSU-12), a widely used multidimensional measure of cigarette craving.METHODS: Daily smokers (n=230) completed the QSU-12, the Fägerstrom Test for Nicotine...

Background. Contrast-enhanced computed tomography is commonly acquired before radiofrequency catheter ablation (RFCA) for atrial fibrillation (AFib) to guide the procedure. We analyzed pulmonary vein (PV) ostial diameter and volumes on a high-definition 64-slice CT (HDCT) scanner in patients with...

Fitness in soil and rhizosphere of Pseudomonas fluorescens C7R12 compared with a C7R12 mutant affected in pyoverdine synthesis and uptake.

FEMS Microbiol Ecol. 2000 Oct 01;34(1):35-44. doi: 10.1111/j.1574-6941.2000.tb00752.x.

Fluorescent pseudomonads have evolved an efficient strategy of iron uptake based on the synthesis of the siderophore pyoverdine and its relevant outer membrane receptor. The possible implication of pyoverdine synthesis and uptake on the ecological competence of a model...

Ligand-stabilized ruthenium nanoparticles: synthesis, organization, and dynamics.

Journal of the American Chemical Society

PMID: 11480979
J Am Chem Soc. 2001 Aug 08;123(31):7584-93. doi: 10.1021/ja003961m.

The decomposition of the ruthenium precursor Ru(COD)(COT) (1, COD = 1,5-cyclooctadiene; COT = 1,3,5-cyclooctatriene) in mild conditions (room temperature, 1--3 bar H(2)) in THF leads, in the presence of a stabilizer (polymer or ligand), to nanoparticles of various sizes...
