Scharnhorst N, Wübbena JB, Hannig S, Jakobsen K, Kramer J, Leroux ID, Schmidt PO.
PMID: 26367634
Opt Express. 2015 Jul 27;23(15):19771-6. doi: 10.1364/OE.23.019771.

We demonstrate phase locking of a 729 nm diode laser to a 1542 nm master laser via an erbium-doped-fiber frequency comb, using a transfer-oscillator feedforward scheme which suppresses the effect of comb noise in an unprecedented 1.8 MHz bandwidth....

Carrier-free Gene Silencing by Amphiphilic Nucleic Acid Conjugates in Differentiated Intestinal Cells.

Moroz E, Lee SH, Yamada K, Halloy F, Martínez-Montero S, Jahns H, Hall J, Damha MJ, Castagner B, Leroux JC.
PMID: 27648924
Mol Ther Nucleic Acids. 2016 Sep 20;5(9):e364. doi: 10.1038/mtna.2016.69.

Nucleic acid therapy can be beneficial for the local treatment of gastrointestinal diseases that currently lack appropriate treatments. Indeed, several oligonucleotides (ONs) are currently progressing through clinical trials as potential treatments for inflammatory bowel diseases. However, due to low...

Autonomous gel/enzyme oscillator fueled by glucose: Preliminary evidence for oscillations.

Chaos (Woodbury, N.Y.)

Leroux JC, Siegel RA.
PMID: 12779824
Chaos. 1999 Jun;9(2):267-275. doi: 10.1063/1.166403.

A novel prototype gel oscillator that functions by dissipating the chemical energy of glucose by an enzyme-mediated reaction is proposed. The product of the reaction modulates the degree of swelling and hence the permeability of a poly(N-isopropylacrylamide-co-methacrylic acid) gel...

Structural analyses of Nd-doped CeO thin films deposited by pulsed laser deposition.

Journal of microscopy

Kopia A, Chmielowska M, Leroux Ch, Dallas JP, Gavarri JR, Kusiński J.

J Microsc. 2006 Oct;224:49-51. doi: 10.1111/j.1365-2818.2006.01661.x.

CeO(2) thin films doped with neodymium oxides for application to gas sensors have been elaborated by the pulsed laser deposition technique. The films were deposited on orientated Si (100) substrates with variable deposition times (t = 90, 180 and...

States of an ensemble of two-level atoms with reduced quantum uncertainty.

Physical review letters

Schleier-Smith MH, Leroux ID, Vuletić V.
PMID: 20366883
Phys Rev Lett. 2010 Feb 19;104(7):073604. doi: 10.1103/PhysRevLett.104.073604. Epub 2010 Feb 18.

We generate entangled states of an ensemble of 5x10{4} 87Rb atoms by optical quantum nondemolition measurement. The resonator-enhanced measurement leaves the atomic ensemble, prepared in a superposition of hyperfine clock levels, in a squeezed spin state. By comparing the...

A randomized controlled trial of home visits by neighborhood mentor mothers to improve children's nutrition in South Africa.

Vulnerable children and youth studies

le Roux IM, le Roux K, Mbeutu K, Comulada WS, Desmond KA, Rotheram-Borus MJ.
PMID: 22299019
Vulnerable Child Youth Stud. 2011 Jun;6(2):91-102. doi: 10.1080/17450128.2011.564224. Epub 2011 Jun 28.

Malnourished children and babies with birth weights under 2500 g are at high risk for negative outcomes over their lifespans. Philani, a paraprofessional home visiting program, was developed to improve nutritional outcomes for young children in South Africa. One...

The [1,2,3]triazolo[1,5-a]pyridine ring: a sensitive sensor for the electronic profile of phosphorus substituents.

Dalton transactions (Cambridge, England : 2003)

Ballesteros-Garrido R, Bonnafoux L, Leroux FR, Abarca B, Colobert F.
PMID: 19562163
Dalton Trans. 2009 Jul 14;(26):5068-70. doi: 10.1039/b906034k. Epub 2009 May 08.

The unique nature of the [1,2,3]triazolo[1,5-a]pyridine reveals without any external perturbation the electronic contribution of various substituents to the phosphorus atom in phosphines, based on the equilibrium of two possible ring-chain isomers.

Orientation-dependent entanglement lifetime in a squeezed atomic clock.

Physical review letters

Leroux ID, Schleier-Smith MH, Vuletić V.
PMID: 20867356
Phys Rev Lett. 2010 Jun 25;104(25):250801. doi: 10.1103/PhysRevLett.104.250801. Epub 2010 Jun 25.

We study experimentally the application of a class of entangled states, squeezed spin states, to the improvement of atomic-clock precision. In the presence of anisotropic noise, the entanglement lifetime is strongly dependent on squeezing orientation. We measure the Allan...

DNA analysis using an integrated microchip for multiplex PCR amplification and electrophoresis for reference samples.
