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, ...
Study of lead levels in soils by weathering of metallic Pb bullets used in dove hunting in Córdoba, Argentina
(2014)
A study of level of Pb in soils of the center-north of the Province of Córdoba, a worldwide recognized tourist region for dove hunting, was performed in this work. The native forest of the region has a great population ...
Implementation of an F-statistic all-sky search for continuous gravitational waves in Virgo VSR1 data
(2014)
We present an implementation of the F -statistic to carry out the first
search in data from the Virgo laser interferometric gravitational wave detector for
periodic gravitational waves from a priori unknown, isolated ...
Recent developments in GEANT 4
(2016)
GEANT4 is a software toolkit for the simulation of the passage of particles through matter. It is used by a large number of experiments and projects in a variety of application domains, including high energy physics, ...
Inverse transition in the dipolar frustrated Ising ferromagnet : the role of domain walls
(2014)
We present a theoretical study aimed at elucidating the origin of the inverse symmetry-breaking transition observed in ultrathin magnetic films with perpendicular anisotropy. We study the behavior of the dipolar frustrated ...
Memory and long-range correlations in chess games
(2014)
In this paper we report the existence of long-range memory in the opening moves of a chronologically ordered set of chess games using an extensive chess database. We used two mapping rules to build discrete time series and ...
Inequality between size and charge in spherical symmetry
(2016)
We prove that, for a charged spherically symmetric body, twice the radius is always strictly greater than the charge of the body. We also prove that this inequality is sharp. Finally, we discuss the physical implications ...
Influence of β-cyclodextrin on the Properties of Norfloxacin Form A
(2014-12-16)
Cyclodextrins are able to form host-guest complexes with hydrophobic molecules to result in the formation of inclusion complexes. The complex formation between norfloxacin form A and β-cyclodextrin was studied by exploring ...
Existence of nonnegative solutions for singular elliptic problems
(2016)
We prove the existence of nonnegative nontrivial weak solutions to the problem −∆u = au−αχ{u>0} − bup in Ω, u = 0 on ∂Ω, where Ω is a bounded domain in Rn. A sufficient condition for the existence of a continuous and ...
