The growth of ice particles in a mixed phase environment based on laboratory observations
(2014)
This paper describes new laboratory observations about the size evolution of ice crystals and cloud droplets immersed in a mixed-phase cloud. The experiments were performed by using a cloud chamber facility for three ...
New geometries for the characterization of dark matter phenomena
(2014)
We present some new geometries with spheroidal symmetry, with and without mass, that involve new kind of energy momentum tensors, and which are suitable for the description of dark matter phenomena.
Search for gravitational wave ringdowns from perturbed intermediate mass black holes in LIGO-Virgo data from 2005-2010
(2014)
We report results from a search for gravitational waves produced by perturbed intermediate mass black holes (IMBH) in data collected by LIGO and Virgo between 2005 and 2010. The search was sensitive to astrophysical sources ...
The index of symmetry of compact naturally reductive spaces
(2014)
We introduce a geometric invariant that we call the index of symmetry, which measures how far is a Riemannian manifold from being a symmetric space. We compute, in a geometric way, the index of symmetry of compact naturally ...
Irradiated graphene as a tunable Floquet topological insulator
(2014)
In the presence of a circularly polarized mid-infrared radiation graphene develops dynamical band gaps in its quasienergy band structure and becomes a Floquet insulator. Here, we analyze how topologically protected edge ...
Virtual laboratory for a first experience in dynamics
(2014)
New technologies contribute to the learning process of scientific disciplines. In particular Physics learning may take advantage of these techniques by implementing experimental practices in simulation environments. Our ...
A Tool for GIXRF/XRR simulation and data analysis
(2014)
The IAEA has developed a beamline end-station facility that it is currently installed at the newly developed XRF beamline of Elettra Sincrotrone Trieste, ItalyThe end-station called Ultra High Vacuum Chamber (UHVC) is ...
Generalization of entropy based divergence measures for symbolic sequence analysis
(2014)
Entropy based measures have been frequently used in symbolic sequence analysis. A symmetrized and smoothed form of Kullback-Leibler divergence or relative entropy, the Jensen-Shannon divergence (JSD), is of particular ...
Isomorphism and disorder in o-chlorohalobenzenes studied by NQR
(2014)
In this work we present experimental results that allow to characterize different solid modifications found in o-chlorohalobenzenes. Three disordered phases have been found in o-chlorobromobenzene. The stable phase at ...
Algebraic functions in quasiprimal algebras
(2014)
A function is algebraic on an algebra A if it can be implicitly defined by a system of equations on A. In this note we give a semantic characterization for algebraic functions on quasiprimal algebras. This characterization ...
