Growth and texture of Spark Plasma Sintered Al2O3 ceramics: a combined analysis of X-rays and Electron Back Scatter Diffraction
Dhanapal Pravarthana, D. Chateigner, L. Lutterotti +7
Textured alumina ceramics were obtained by Spark Plasma Sintering (SPS) of undoped commercial a-Al2O3 powders. Various parameters (density, grain growth, grain size distribution) o…
Real and complex rank for real symmetric tensors with low ranks
Edoardo Ballico, Alessandra Bernardi
We study the case of a real homogeneous polynomial whose minimal real and complex decompositions in terms of powers of linear forms are different. We prove that, if the sum of…
On the gonality sequence of smooth curves: normalizations of singular curves in a quadric surface
Edoardo Ballico
Let be a smooth curve of genus . For each positive integer the -gonality of is the minimal integer such that there is with $h^0(C,L…
An event-based model for contracts
Massimo Bartoletti, Tiziana Cimoli, G. Michele Pinna +1
We introduce a basic model for contracts. Our model extends event structures with a new relation, which faithfully captures the circular dependencies among contract clauses. We est…
The (Un)Reliability of NVD Vulnerable Versions Data: an Empirical Experiment on Google Chrome Vulnerabilities
Viet Hung Nguyen, Fabio Massacci
NVD is one of the most popular databases used by researchers to conduct empirical research on data sets of vulnerabilities. Our recent analysis on Chrome vulnerability data reporte…
Scaling solutions of the two fluid hydrodynamic equations in a harmonically trapped gas at unitarity
Yan-Hua Hou, Lev P. Pitaevskii, Sandro Stringari
We prove that the two fluid Landau hydrodynamic equations, when applied to a gas interacting with infinite scattering length (unitary gas) in the presence of harmonic trapping, adm…
