Biology of the gametes of some teleost species.

Fish physiology and biochemistry

Billard R, Christen R, Cosson MP, Gatty JL, Letellier L, Renard P, Saad A.
PMID: 24233173
Fish Physiol Biochem. 1986 Oct;2(1):115-20. doi: 10.1007/BF02264079.

Our knowledge of the biology of fish gametes is still limited. Up to now research was short-term, aiming at solving practical questions connected with gamete storage and artificial insemination. More information on gamete biology is now available and has...

Multichannel intermittencies induced by symmetries.

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

Letellier C, Werny P, Malasoma JM, Gilmore R.
PMID: 12366237
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Sep;66(3):036220. doi: 10.1103/PhysRevE.66.036220. Epub 2002 Sep 27.

Type-I intermittencies are common phenomena that are often observed in the neighborhood of periodic windows when a control parameter is varied. These intermittencies usually have a single reinjection channel, that is, a single type of laminar phase was observed....

Experimental evidence for a torus breakdown in a glow discharge plasma.

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

Letellier C, Dinklage A, El-Naggar H, Wilke C, Bonhomme G.
PMID: 11308891
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Apr;63(4):042702. doi: 10.1103/PhysRevE.63.042702. Epub 2001 Mar 29.

A global bifurcation scenario for a two-frequency torus breakdown depicted by Baptista and Caldas [Physica D 132, 325 (1999)] is observed on a glow-discharge experiment. The torus is broken through a crisis with an unstable periodic orbit. The torus...

Modeling maps by using rational functions.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Menard O, Letellier C, Maquet J, Gouesbet G.
PMID: 11101966
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 Nov;62(5):6325-31. doi: 10.1103/physreve.62.6325.

Rational functions are not very useful for obtaining global differential models because they involve poles that may eject the trajectory to infinity. In contrast, it is here shown that they allow one to significantly improve the quality of models...

Ion-selective electrode for dodecyldimethylamine oxide: a "twice-Nernstian" slope for the determination of a neutral component.

Analytical chemistry

Peyre V, Baillet S, Letellier P.
PMID: 10857608
Anal Chem. 2000 Jun 01;72(11):2377-82. doi: 10.1021/ac9911387.

An electrode originally sensitive to dodecyltrimethylammonium (DTA+) was proven to be sensitive to dodecyldimethylamine oxide (DDAO), a surfactant with acidobasic properties. The response of the electrode was tested from pH 2 to 9.3. Its slope is Nernstian when the...

Structure selection for global vector field reconstruction by using the identification of fixed points.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Le Sceller L, Letellier C, Gouesbet G.
PMID: 11969922
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 1999 Aug;60(2):1600-6. doi: 10.1103/physreve.60.1600.

Global vector field reconstruction is a well established technique to provide phenomenological models from nonlinear data, in particular when all information is contained in a so-called standard function. In the case when the standard function is taken as a...

Investigating nonlinear dynamics from time series: The influence of symmetries and the choice of observables.

Chaos (Woodbury, N.Y.)

Letellier C, Aguirre LA.
PMID: 12779585
Chaos. 2002 Sep;12(3):549-558. doi: 10.1063/1.1487570.

When a dynamical system is investigated from a time series, one of the most challenging problems is to obtain a model that reproduces the underlying dynamics. Many papers have been devoted to this problem but very few have considered...

Graphical interpretation of observability in terms of feedback circuits.

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

Letellier C, Aguirre LA.
PMID: 16383722
Phys Rev E Stat Nonlin Soft Matter Phys. 2005 Nov;72(5):056202. doi: 10.1103/PhysRevE.72.056202. Epub 2005 Nov 01.

It is known that the observability of a system depends crucially on the choice of the observable. Locally, such a feature results directly from the couplings between the dynamical variables (globally, it will also depend on symmetry). Using a...

Piecewise affine models of chaotic attractors: the Rossler and Lorenz systems.

Chaos (Woodbury, N.Y.)

Amaral GF, Letellier C, Aguirre LA.
PMID: 16599746
Chaos. 2006 Mar;16(1):013115. doi: 10.1063/1.2149527.

This paper proposes a procedure by which it is possible to synthesize Rossler [Phys. Lett. A 57, 397-398 (1976)] and Lorenz [J. Atmos. Sci. 20, 130-141 (1963)] dynamics by means of only two affine linear systems and an abrupt...

Membrane electrodes sensitive to doubly charged surfactants. Application to a cationic gemini surfactant.

Talanta

Sirieix-Plénet J, Turmine M, Letellier P.
PMID: 18969132
Talanta. 2003 Jul 27;60(5):1071-8. doi: 10.1016/S0039-9140(03)00192-9.

The response of a membrane electrode is not always identical to that of a redox electrode. Indeed, in the case of membrane electrode the response is not due to a redox equilibrium but to a cross-membrane potential. So, the...

Modification of the wettability of a polymeric substrate by pH effect. Determination of the surface acid dissociation constant by contact angle measurements.

Langmuir : the ACS journal of surfaces and colloids

Badre C, Mayaffre A, Letellier P, Turmine M.
PMID: 16981758
Langmuir. 2006 Sep 26;22(20):8424-30. doi: 10.1021/la061324p.

The wetting properties of a substrate can be changed by chemical reaction. Here, we studied simple materials with acid-base properties, by preparing poly(vinyl chloride) films containing lauric acid. These substrates constitute simple polymeric surfaces the wettability of which can...

Micellar aggregation for ionic surfactant in pure solvent and electrolyte solution: nonextensive thermodynamics approach.

Journal of colloid and interface science

Letellier P, Mayaffre A, Turmine M.
PMID: 18275968
J Colloid Interface Sci. 2008 May 01;321(1):195-204. doi: 10.1016/j.jcis.2008.01.030. Epub 2008 Jan 29.

We show in this study that the concepts of nonextensive thermodynamics introduced and applied in a series of previous studies can be used to describe the behaviour of ionic surfactant solutions at concentrations higher than the critical micelle concentration...
