Neutron capture cross section of unstable 63Ni: implications for stellar nucleosynthesis
C. Lederer, C. Massimi, S. Altstadt +102
The Ni() cross section has been measured for the first time at the neutron time-of-flight facility n\_TOF at CERN from thermal neutron energies up to 200 keV. In total…
Universal Lagrangian Bundles
Daniele Sepe
The obstruction to construct a Lagrangian bundle over a fixed integral affine manifold was constructed by Dazord and Delzant in \cite{daz_delz} and shown to be given by `twisted' c…
Beyond Concordance Cosmology with Magnification of Gravitational-Wave Standard Sirens
Stefano Camera, Atsushi Nishizawa
We show how future gravitational-wave detectors would be able of discriminating between the concordance LCDM cosmological model and up-to-date competing alternatives, e.g. dynamica…
The Redner - Ben-Avraham - Kahng cluster system
F. P da Costa, J. T. Pinto, R. Sasportes
We consider a coagulation model first introduced by Redner, Ben-Avraham and Krapivsky in [Redner, Ben-Avraham, Kahng: Kinetics of 'cluster eating', J. Phys. A: Math. Gen., 20 (1987…
Towards the Rapid Development of a Natural Language Understanding Module
Catarina Moreira, Ana Cristina Mendes, Luísa Coheur +1
When developing a conversational agent, there is often an urgent need to have a prototype available in order to test the application with real users. A Wizard of Oz is a possibilit…
Learning to Rank for Expert Search in Digital Libraries of Academic Publications
Catarina Moreira, Pável Calado, Bruno Martins
The task of expert finding has been getting increasing attention in information retrieval literature. However, the current state-of-the-art is still lacking in principled approache…
