BACKGROUND: Although within Latin America Chile has one of the lowest birth rates among adolescents, it has a high rate in comparison to other developed nations.AIM: To explore trends in birth rates among adolescents by selected demographics in Chile.METHODS:...

Hydrodynamic evolution of plasma waveguides for soft-x-ray amplifiers.

Physical review. E

Oliva E, Depresseux A, Cotelo M, Lifschitz A, Tissandier F, Gautier J, Maynard G, Velarde P, Sebban S.
PMID: 29548124
Phys Rev E. 2018 Feb;97(2):023203. doi: 10.1103/PhysRevE.97.023203.

High-density, collisionally pumped plasma-based soft-x-ray lasers have recently delivered hundreds of femtosecond pulses, breaking the longstanding barrier of one picosecond. To pump these amplifiers an intense infrared pulse must propagate focused throughout all the length of the amplifier, which...

BACKGROUND: Glioblastoma (GBM) is a poorly immunogenic neoplasm treated with focused radiation. Immunotherapy has demonstrated synergistic survival effects with stereotactic radiosurgery (SRS) in murine GBM. GITR is a co-stimulatory molecule expressed constitutively on regulatory T-cells and by effector T-cells...

PMID: 8812512
Gynecol Oncol. 1996 Apr;61(1):11-5.

Six hundred thirty-nine patients with CIN on referral Pap were evaluated cytocolposcopically at the first visit and decided whether to be treated the same day or not. One hundred ninety-two patients (30%) were considered negative. Follow-up evidenced later appearance...

Dissipative Toda-Rayleigh lattice and its oscillatory modes.

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

Makarov VA, del Río E, Ebeling W, Velarde MG.
PMID: 11580456
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Sep;64(3):036601. doi: 10.1103/PhysRevE.64.036601. Epub 2001 Aug 14.

A detailed theoretical and experimental analysis of the possible oscillatory regimes of the dissipative Toda-Rayleigh lattice system is provided. It is shown that the system has (N-1) oscillatory modes with different space-time scales and two rotatory modes. Using its...

On the Spreading of Partially Miscible Liquids.

Journal of colloid and interface science

Santiago-Rosanne M, Vignes-Adler M, Velarde MG.
PMID: 11161524
J Colloid Interface Sci. 2001 Feb 15;234(2):375-383. doi: 10.1006/jcis.2000.7287.

As time proceeds, partially miscible liquids spread as a cap surrounded by a primary film according to power laws, t(n), for both the leading edge (front) and the central cap. The corresponding exponents depend on the thickness, H, of...

On the Interfacial Deformation of a Magnetic Liquid Drop under the Simultaneous Action of Electric and Magnetic Fields.

Journal of colloid and interface science

PMID: 11237441
J Colloid Interface Sci. 2001 Mar 01;235(1):46-58. doi: 10.1006/jcis.2000.7334.

The influence of uniform constant magnetic and electric fields, acting simultaneously, on a magnetic fluid drop is theoretically investigated. The drop is suspended in another magnetic fluid that is immiscible with the former. Both fluids are regarded as incompressible,...

Capillary imbibition of surfactant solutions in porous media and thin capillaries: partial wetting case.

Journal of colloid and interface science

Starov VM, Zhdanov SA, Velarde MG.

The capillary imbibition of aqueous surfactant solutions into dry porous substrates is investigated from both theoretical and experimental points of view in the case of partial wetting. Cylindrical capillaries are used as a model of porous media to study...

Polymer monolayers with a small viscoelastic linear regime: equilibrium and rheology of poly(octadecyl acrylate) and poly(vinyl stearate).

The equilibrium properties of monolayers of two polymers: poly(octadecyl acrylate) and poly(vinyl stearate) on water have been measured. The surface pressure (Pi) versus surface concentration (Gamma) curves indicate that the water-air interface is a poor solvent for both polymers....
