Using videos to improve oral presentation skills in distance learning engineering master's degrees
(Taylor & Francis, 2019-09-11)
In this paper we present a pilot study to improve the learning process on distance learning Engineering master's degrees. We propose an activity where the students individually produce a video in which they explain the ...
Efficient time integration methods for Gross-Pitaevskii equations with rotation term
(American Institute of Mathematical Sciences, 2019)
The objective of this work is the introduction and investigation of favourable time integration methods for the Gross-Pitaevskii equation with rotation term. Employing a reformulation in rotating Lagrangian coordinates, ...
Sex differences in gray matter volume: how many and how large are they really?
(BMC, 2019-07-01)
Background:
Studies assessing volumetric sex differences have provided contradictory results. Total intracranial volume (TIV) is a major confounding factor when estimating local volumes of interest (VOIs). We investigated ...
Multiple photon effective Hamiltonians in linear quantum optical networks
(Elsevier, 2019)
We give an alternative derivation for the explicit formula of the effective Hamiltonian describing the evolution
of the quantum state of any number of photons entering a linear optics multiport. The description is based ...
Novel symplectic integrators for the Klein-Gordon equation with space- and time-dependent mass
(Elsevier, 2019-04)
We consider the numerical time-integration of the non-stationary Klein–Gordon equation with position- and time-dependent mass. A novel class of time-averaged symplectic splitting methods involving double commutators is ...
Generalized Weierstrass semigroups and their Poincaré series.
(Elsevier, 2019-07)
We investigate the structure of the generalized Weierstrass semigroups at several points on a curve defined over a finite field. We present a description of these semigroups that enables us to associate them with combinatorial ...
Maximal lp-regularity for discrete time Volterra equations with delay
(Taylor & Francis, 2019-07-08)
In this paper, we investigate the existence and uniqueness of solutions belonging to the vector-valued space ℓp(Z,X) by using Blunck's theorem on the equivalence between operator-valued ℓp-multipliers and the notion of ...
Method to determine which quantum operations can be realized with linear optics with a constructive implementation recipe
(American Physical Society, 2019-08-02)
The evolution of quantum light through linear optical devices can be described by the scattering matrix S of the system. For linear optical systems with m possible modes, the evolution of n input photons is given by a ...
Global and Local Three-dimensional Studies of The Residual Vector Field from 2MASS and Hipparcos-2 Catalog
(Astronomical Society of the PacificIOP, 2019-04)
The Gaia mission will provide a six-parameter solution for millions of stars, including a tridimensional map of our Galaxy. The estimation of distances has been made for the Tycho-Gaia Astrometric Solution (TGAS), while ...
Occultation of Planets by the Moon in European Narrative Medieval Sources
(Sage, 2019-05)
Existing research dealing with astronomical observations from medieval Europe have
extensively covered topics such as solar and lunar eclipses and sightings of comets and meteors, but no
compilation of occultations of ...
