Towards a precise determination of the topological susceptibility in the SU(3) Yang-Mills theory
An ongoing effort to compute the topological susceptibility for the SU(3)
Yang-Mills theory in the continuum limit with a precison of about 2% is
reported. The susceptibility is computed by using the definition of the charge
suggested by Neuberger fermions for two values of the negative mass parameter
s. Finite volume and discretization effects are estimated to meet this level of
precision. The large statistics required has been obtained by using PCs of the
INFN-GRID. Simulations with larger lattice volumes are necessary in order to
better understanding the continuum limit at small lattice spacing values.Comment: 8 pages, 2 figures, The XXVII International Symposium on Lattice

Large statistics study of the topological charge distribution in the SU(3) gauge theory
We present preliminary results for a high statistics study of the topological
charge distribution in the SU(3) Yang-Mills theory obtained by using the
definition of the charge suggested by Neuberger fermions. We find statistical
evidence for deviations from a gaussian distribution. The large statistics
required has been obtained by using PCs of the INFN-GRID.Comment: Talk given at the 24th International Symposium on Lattice Field

Reply to âComment on âDependence of shear wave seismoelectrics on soil textures: a numerical study in the vadose zone by F.I. Zyserman, L.B. Monachesi and L. Jouniauxâ by Revil, A.â
In this paper we reply to a the comment made by Revil (2017) on our paper (2017, Geophys. J. Int., 208), where we describe seismoelectric phenomena in the vadose zone based on the theory of Pride empirically extended for unsaturated conditions. We analyse and answer each one of the enumerated critics, and reaffirm the conclusions of our work. In particular, we prove that using the conductivity model suggested by Revil (2017) does not change our predictions significantly, contrary to what was argued in the comment. Further, in the light of previous and new theoretical and experimental results existing in the literature, we confirm the reasonability of having tested a non-monotonic saturation dependent streaming potential coefficient model besides the monotonic one, and discuss the suitability of assuming a linear relation between the permeability and the excess charge.Fil: Zyserman, Fabio Ivan.

Solvability and uniqueness criteria for generalized Sylvester-type equations
We provide necessary and sufficient conditions for the generalized
-Sylvester matrix equation, , to have exactly one
solution for any right-hand side E. These conditions are given for arbitrary
coefficient matrices (either square or rectangular) and generalize
existing results for the same equation with square coefficients. We also review
the known results regarding the existence and uniqueness of solution for
generalized Sylvester and -Sylvester equations.Comment: This new version corrects some inaccuracies in corollaries 7 and
Smart Specialisation Strategies for Supporting Europe 2020 Vision. Looking at the American Experience: the Case of the Boston Area
These reflections aim to highlight the crucial challenge that European Regions are called to face applying the âResearch and Innovation Strategies for Smart Specializationâ policy for pursuing the virtuous implementation of EU Cohesion Policy and âEurope 2020â Agenda. The original cultural style of the âUS Smart Specialization modelâ, supported by the âcluster theoryâ and the âinnovation paradigmâ, represents a significant lesson in Boston area
