Nonlocal Delaunay surfaces
(2016)
We construct codimension 1 surfaces of any dimension that minimize a periodic nonlocal perimeter functional among surfaces that are periodic, cylindrically symmetric and decreasing. These surfaces may be seen as a nonlocal ...
The stability of hollow nanoparticles and the simulation temperature ramp
(2018)
Hollow nanoparticles (hNPs) are of interest because their large cavities and small thickness give rise to a large surface to volume ratio. However, in general they are not in equilibrium and far from their global energy ...
Antispeciesist apories related to death in nonhuman animals
(2018)
The problem of speciesism, is not only related to the fact of the deliberated infliction of pain or suffering to nonhuman animals, but also with the phenomenon of putting an end to their lives. From this consideration, ...
Default. Design and neuroscience: interactive work on brain activity at rest
(2018)
Contrary to what was previously thought, the brain is never inactive. In fact, its greatest lucidity is evidenced when it does not pay attention to external stimuli. The interactive installation Default arises from this ...
Negative interest rates: why and how?
(2017)
Interest rates (or nominal yields) can be negative, this is an unavoidable fact which has already been visible during the Great Depression (1929-39). Nowadays we can find negative rates easily by e.g. auditing. Several ...
On the c-1 robust transitivity of the geometric lorenz attractor
(2017)
The geometric Lorenz attractor is an attractor set constructed in such a way that it satisfies the main qualitative properties evidenced on the Lorenz system equations, particularly the fact that this attractor is a robustly ...
Saddle node bifurcation: appearance mechanism of pulses in the subcritical complex Ginzburg-Landau equation
(2003)
We study stationary, localized solutions in the complex subcritical Ginzburg-Landau equation in the region where there exists coexistence of homogeneous attractors. Using a matching approach, we report on the fact that the ...
Shh activity and localization is regulated by perlecan.
(2011)
Proliferation and cell fate determination in the developing embryo are extrinsically regulated by multiple interactions among diverse secreted factors, such as Sonic Hedgehog (SHh), which act in a concentration-dependent ...
