Language Bootstrapping: Learning Word Meanings From Perception-Action Association
Giampiero Salvi, Luis Montesano, Alexandre Bernardino +1
We address the problem of bootstrapping language acquisition for an artificial system similarly to what is observed in experiments with human infants. Our method works by associati…
The wind and the magnetospheric accretion onto the T Tauri star S Coronae Australis at sub-au resolution
R. Garcia Lopez, K. Perraut, A. Caratti o Garatti +70
To investigate the inner regions of protoplanetary disks, we performed near-infrared interferometric observations of the classical TTauri binary system S CrA. We present the first…
Comparison between measured and predicted turbulence frequency spectra in ITG and TEM regimes
J. Citrin, H. Arnichand, J. Bernardo +6
The observation of distinct peaks in tokamak core reflectometry measurements - named quasi-coherent-modes (QCMs) - are identified as a signature of Trapped-Electron-Mode (TEM) turb…
BPS states, knots and quivers
Piotr Kucharski, Markus Reineke, Marko Stosic +1
We argue how to identify supersymmetric quiver quantum mechanics description of BPS states, which arise in string theory in brane systems representing knots. This leads to a surpri…
Covariant spectator theory of quark-antiquark bound states: Mass spectra and vertex functions of heavy and heavy-light mesons
Sofia Leitão, Alfred Stadler, M. T. Peña +1
We use the covariant spectator theory with an effective quark-antiquark interaction, containing Lorentz scalar, pseudoscalar, and vector contributions, to calculate the masses and…
A Theoretical Study of the Outer Layers of Eight Kepler F-stars: The Relevance of Ionization Processes
Ana Brito, Ilídio Lopes
We have analyzed the theoretical model envelopes of eight Kepler F-stars by computing the phase shift of the acoustic waves, , and its related function, . The latter is…
