Narrow-band search of continuous gravitational-wave signals from Crab and Vela pulsars in Virgo VSR4 data
(2015)
In this paper we present the results of a coherent narrow-band search for continuous gravitational-wave signals from the Crab and Vela pulsars conducted on Virgo VSR4 data. In order to take into account a possible small ...
Adapting a Fourier pseudospectral method to Dirichlet boundary conditions for Rayleigh–Bénard convection
(2015)
We present the adaptation to non–free boundary conditions of a pseudospectral method based on the (complex) Fourier transform. The method is applied to the numerical integration of the Oberbeck–Boussinesq equations in a ...
Internal - External stimulus competition in a system of interacting moving particles : persuasion vs propaganda
(2015)
We propose a general nonlinear analytical framework to study the effect of an external stimulus in the internal state of a population of moving particles. This novel scheme allows us to study a broad range of excitation ...
Sustainable chemotherapy schedules
(2015)
We used a discrete time version of viabilitytheory in order to study the sustainable therapies againstthe cancer. We assume that the tumor is composed of twosubpopulations, one resistant and the another sensitive. Weconsider ...
Explicit matrix inverses for lower triangular matrices with entries involving Jacobi polynomials
(2015)
For a two-parameter family of lower triangular matrices with entries involving Jacobi polynomials an explicit inverse is given, with entries involving a sum of two Jacobi polynomials. The formula simplifies in the Gegenbauer ...
Weighted estimates for integral operators on local BMO type spaces
(2015)
We prove the weighted boundedness for a family of integral operators Tα on Lebesgue spaces and local BMO type spaces. To this end we show that Tα can be controlled by the Calder ́on operator and a local maximal operator. ...
Directed search for gravitational waves from Scorpius X-1 with initial LIGO data
(2015)
We present results of a search for continuously emitted gravitational radiation, directed at the brightest low-mass x-ray binary, Scorpius X-1. Our semicoherent analysis covers 10 days of LIGO S5 data ranging from 50–550 ...
Experimental determination of multiple ionization cross sections in Si by electron impact
(2015)
The thin sample method is often used to experimentally determine ionization cross sections, specially when focusing on the low overvoltage region. The simplicity of the formalism involved in this method is very appealing, ...
Normal holonomy of orbits and Veronese submanifolds
(2015)
It was conjectured, twenty years ago, the following result that would generalize the so-called rank rigidity theorem for homogeneous Euclidean submanifolds: let Mn, n ≥ 2, be a full and irreducible homogeneous submanifold ...
Combining semi-supervised and active learning to recognize minority senses in a new corpus
(2015)
In this paper we study the impact of combining active learning with bootstrapping to grow a small annotated corpus from a different, unannotated corpus. The intuition underlying our approach is that bootstrapping includes ...
