Nonlinear driven diffusive systems with dissipation: Fluctuating hydrodynamics
(American Physical Society, 2012)
We consider a general class of nonlinear diffusive models with bulk dissipation and boundary driving and derive its hydrodynamic description in the large size limit. Both the average macroscopic behavior and the fluctuating ...

The nature of the gould belt from a fractal analysis of its stellar population
(IOP Publishing Ltd., 2007-09-20)
he Gould Belt (GB) is a system of gas and young, bright stars distributed along a plane that is inclined with respect to the main plane of the Milky Way. Observational evidence suggests that the GB is our closest star ...

Kinetic theory of a confined quasi-one-dimensional gas of hard disks
(Elsevier, 2022)
A dilute gas of hard disks confined between two straight parallel lines is considered. The distance between the two boundaries is between one and two particle diameters, so that the system is quasi-one-dimensional. A ...

Meson-exchange currents and final-state interactions in quasielastic electron scattering at high momentum transfers
(The American Physical Society, 2010)
The effects of meson-exchange currents (MEC) are computed for the one-particle one-hole transverse response function for finite nuclei at high momentum transfers q in the region of the quasi-elastic peak. A semirelativistic ...

Wetting transition of a nematic liquid crystal on a periodic wedge-structured substrate
(EDP Sciences, 2007)
It is known that the wetting behaviour of a fluid is deeply altered by the presence of rough or structured substrates. We first review some simple considerations about isotropic fluids and rough substrates, and then we ...

Comparative analysis of the germination of barley seeds subjected to drying, hydrogen peroxide, or oxidative air plasma treatments
(Wiley-Blackwell, 2022)
Acceleration in germination time by 12–24 h for barley seeds treated with atmospheric air plasmas may have a significant economic impact on malting processes. In this study, the increase in germination rate and decrease ...

Disentangling phase transitions and critical points in the proton-neutron interacting boson model by catastrophe theory
(Elsevier, 2014)
We introduce the basic concepts of catastrophe theory needed to derive analytically the phase diagram of the proton–neutron interacting boson model (IBM-2). Previous studies [1–3] were based on numerical solutions. We here ...

Unraveling Discharge and Surface Mechanisms in Plasma-Assisted Ammonia Reactions
(American Chemical Society, 2020)
Current studies on ammonia synthesis by means of atmospheric pressure plasmas respond to the urgent need of developing less environmentally aggressive processes than the conventional Haber-Bosch catalytic reaction. Herein, ...

The alhambra survey: evolution of galaxy spectral segregation
(IOP Publishing Ltd., 2016-02-20)
We study the clustering of galaxies as a function of spectral type and redshift in the range 0.35 <z <1.1 using data from the Advanced Large Homogeneous Area Medium Band Redshift Astronomical (ALHAMBRA) survey. The data ...

Reactions induced by 9Be in a four-body continuum-discretized coupled-channels framework
(Springer Nature, 2015-06-01)
We investigate the elastic scattering of 9Be on 208Pb at beam energies above (50MeV) and below (40MeV) the Coulomb barrier. The reaction is described within a four-body framework using the Continuum-Discretized Coupled-Channels ...
