Wrinkling crystallography on spherical surfaces.

Proceedings of the National Academy of Sciences of the United States of America

Brojan M, Terwagne D, Lagrange R, Reis PM.
PMID: 25535355
Proc Natl Acad Sci U S A. 2015 Jan 06;112(1):14-9. doi: 10.1073/pnas.1411559112. Epub 2014 Dec 22.

We present the results of an experimental investigation on the crystallography of the dimpled patterns obtained through wrinkling of a curved elastic system. Our macroscopic samples comprise a thin hemispherical shell bound to an equally curved compliant substrate. Under...

Assessment of individual and conspecific reproductive success as determinants of breeding dispersal of female tree swallows: A capture-recapture approach.

Ecology and evolution

Lagrange P, Gimenez O, Doligez B, Pradel R, Garant D, Pelletier F, Bélisle M.
PMID: 28944020
Ecol Evol. 2017 Aug 09;7(18):7334-7346. doi: 10.1002/ece3.3241. eCollection 2017 Sep.

Breeding dispersal is a key process of population structure and dynamics and is often triggered by an individual's breeding failure. In both colonial and territorial birds, reproductive success of conspecifics (RSc) can also lead individuals to change breeding sites...

Imaging and electron energy-loss spectroscopy using single nanosecond electron pulses.

Ultramicroscopy

Picher M, Bücker K, LaGrange T, Banhart F.
PMID: 29547872
Ultramicroscopy. 2018 May;188:41-47. doi: 10.1016/j.ultramic.2018.03.006. Epub 2018 Mar 13.

We implement a parametric study with single electron pulses having a 7 ns duration to find the optimal conditions for imaging, diffraction, and electron energy-loss spectroscopy (EELS) in the single-shot approach. Photoelectron pulses are generated by illuminating a flat...

Patient-Provider Communication About Prostate Cancer Screening and Treatment: New Evidence From the Health Information National Trends Survey.

American journal of men's health

Bhuyan SS, Chandak A, Gupta N, Isharwal S, LaGrange C, Mahmood A, Gentry D.
PMID: 26614441
Am J Mens Health. 2017 Jan;11(1):134-146. doi: 10.1177/1557988315614082. Epub 2016 Jul 07.

The American Urological Association, American Cancer Society, and American College of Physicians recommend that patients and providers make a shared decision with respect to prostate-specific antigen (PSA) testing for prostate cancer (PCa). The goal of this study is to...

A powerful route to C-functionalised tetraazamacrocycles.

Chemical communications (Cambridge, England)

Boschetti F, Denat F, Espinosa E, Lagrange JM, Guilard R.
PMID: 14973621
Chem Commun (Camb). 2004 Mar 07;(5):588-9. doi: 10.1039/b315285e. Epub 2004 Feb 03.

The bisaminal template approach represents a powerful synthetic tool for the preparation of various C-functionalised tetraazacycloalkanes which are efficient precursors of bifunctional chelating agents.

Velocity locking of incoherent nonlinear wave packets.

Physical review letters

Pitois S, Lagrange S, Jauslin HR, Picozzi A.
PMID: 16907501
Phys Rev Lett. 2006 Jul 21;97(3):033902. doi: 10.1103/PhysRevLett.97.033902. Epub 2006 Jul 19.

We show both theoretically and experimentally in an optical fiber system that a set of incoherent nonlinear waves irreversibly evolves to a specific equilibrium state, in which the individual wave packets propagate with identical group velocities. This intriguing process...

Solving the accelerator-condenser coupling problem in a nanosecond dynamic transmission electron microscope.

Reed BW, LaGrange T, Shuttlesworth RM, Gibson DJ, Campbell GH, Browning ND.
PMID: 20515144
Rev Sci Instrum. 2010 May;81(5):053706. doi: 10.1063/1.3427234.

We describe a modification to a transmission electron microscope (TEM) that allows it to briefly (using a pulsed-laser-driven photocathode) operate at currents in excess of 10 mA while keeping the effects of condenser lens aberrations to a minimum. This...

Singular tori as attractors of four-wave-interaction systems.

Physical review. E, Statistical, nonlinear, and soft matter physics

Lagrange S, Sugny D, Picozzi A, Jauslin HR.
PMID: 20365441
Phys Rev E Stat Nonlin Soft Matter Phys. 2010 Jan;81(1):016202. doi: 10.1103/PhysRevE.81.016202. Epub 2010 Jan 07.

We study the spatiotemporal dynamics of the Hamiltonian four-wave interaction in its counterpropagating configuration. The numerical simulations reveal that, under rather general conditions, the four-wave system exhibits a relaxation process toward a stationary state. Considering the Hamiltonian system associated...
