Structural and magnetic changes induced by electron and ion irradiation on HOPG
(2015)
In recent decades, many studies reported magnetism in carbon-based materials. This phenomenon was attributed to structural defects within the sample. Many authors showed an increase of magnetization in HOPG (Highly Oriented ...
On stochastic spatial patterns and neuronal polarity
(2014)
Polarization refers to asymmetric changes in cellular organization that occur in response to external or internal signals. Although neurons can spontaneously establish and maintain asymmetric distributions of signalling ...
Lightning activity in the Southern Coast of Chile
(2014)
Based on eight years of lightning data (from January 2005 to December 2012) from the World Wide Lightning Location Network (WWLLN) we describe the spatial distribution and temporal variability of lightning activity over ...
Reaction rate in an evanescent random walkers system
(2015)
Diffusion mediated reaction models are particularly ubiquitous in the description of phys-ical, chemical or biological processes. The random walk schema is a useful tool for formu-lating these models. Recently, evanescent ...
Floquet chiral edge states in graphene
(2014)
We report on the emergence of laser-induced chiral edge states in graphene ribbons. Insights on the nature of these Floquet states is provided by an analytical solution which is complemented with numerical simulations of ...
On a mathematical theory of complex systems on networs with application to opinion formation
(2014)
This paper presents a development of the so-called kinetic theory for active particles to the modeling of living, hence complex, systems localized in networks. The overall system is viewed as a network of interacting nodes, ...
Internal dosimetry for alpha emitters radiopharmaceuticals in biological tissue studied with the FLUKA code
(2014)
Nuclear medicine clinical practices for neoplasic disease diagnose and treatment are based on the incorporation of α, β and γ radiotracers and radiopharmaceuticals, which might be associated with potential damage. Thus, ...
On the theorem of the primitive element with applications to the representation theory of associative and Lie algebras
(2014)
We describe all finite dimensional uniserial representations of a commutative associative (resp. abelian Lie) algebra over a perfect (resp. sufficiently large perfect) field. In the Lie case the size of the field depends ...
Intrinsic angular momentum for radiating spacetimes which agrees with the Komar integral in the axisymmetric case
(2014)
Here, we present a new definition of intrinsic angular momentum at future null infinity, based on the charge-integral approach. This definition is suitable for the general case of radiating spacetimes without symmetries, ...
A Natural Language Instructor for pedestrian navigation based in generation by selection
(Association for Computational Linguistics, 2014)
In this paper we describe a method for developing a virtual instructor for pedestrian navigation based on real interactions between a human instructor and a human pedestrian. A virtual instructor is an agent capable ...
