Wannier90 as a community code: new features and applications
2019
Wannier90 is an open-source computer program for calculating maximally-localised Wannier functions (MLWFs) from a set of Bloch states. It is interfaced to many widely used electronic-structure codes thanks to its independence from the basis sets representing these Bloch states. In the past few years the development of Wannier90 has transitioned to a community-driven model; this has resulted in a number of new developments that have been recently released in Wannier90 v3.0. In this article we describe these new functionalities, that include the implementation of new features for wannierisation and disentanglement (symmetry-adapted Wannier functions, selectively-localised Wannier functions, s…
CRACK PROPAGATION IN FINITE ELEMENTS AUGMENTED WITH EMBEDDED INTERPHASES
2022
In the FE analysis of quasi-brittle materials, one of the main issues is how to correctly capture cracks propagation. In particular, under specific load intensity, strains progressively localize in narrow bands, leading to a global nonlinear softening response until collapse. A variety of FE models have been proposed, which may be separated in two main groups: discrete crack models and continuous models. Discrete crack models introduce a discontinuity along the inter-element boundaries or inside elements (intra-element discontinuity). Continuous models modify the constitutive relations of the local material to better describe its behaviour in presence of a fracture. In the framework of intr…
"Young people, from problem to resource": a model of youth policy
2018
[Resumen] A partir de los últimos diagnósticos relativos a la juventud en el espacio iberoamericano (CEPAL/OIJ, 2004 y 2008), se identificaron una serie de tensiones y paradojas que enfrentan los jóvenes en sus procesos de desarrollo y de inclusión social. Para conciliar estas paradojas y lograr que los jóvenes de la región puedan realizar su potencial y contribuir a construir sociedades más igualitarias y productivas, se requieren políticas que consideren al sujeto joven en su integralidad. El artículo presenta una política juvenil, desarrollada en el Sur de Italia desde 2006 hasta la actualidad, dirigida a los jóvenes y orientada a la promoción de su activación. El planteamiento de esta p…
Trattamento endovescicale alternativo al BCG nel carcinoma vescicale NMI a rischio intermedio o elevato
2013
Endovesical treatment as an alternative to BCG for intermediate or high-risk NMI bladder cancer A shortage of BCG is foreseen till the end of 2013. Which will be the management of intermediate and high-risk NMI-BC if BCG will not be available? In patients harboring high-risk NMI tumors, particularly T1G3 and Tis, the first therapeutic choice is radical cystectomy. Device-assisted therapies, although showing promising results, should be considered only for selected patients. In intermediate risk patients, intravesical chemotherapy remains a legitimate option even if BCG is available. Thus, in a period of BCG shortage, intravesical chemotherapy should be offered, preferably preceded by early …
Pedagogia Social i investigació aplicada. Aproximació a una dècada de quefer universitari a Galícia
2012
Aquest article presenta els elements clau de sis projectes d'investigació alicada dins la realitat local gallega entre els anys 2001 i 2011. Tots ells han sigut realitzats pel grup SEPA (Pedagogia Social i Educació Ambiental) de la Universitat de Santiago de Compostela en conveni amb diverses entitats; en els casos que s'analitzen, ajuntaments, Diputació, Fundació Ciutat de la Cultura de Galicia i Eix Atlàntic del Nord-oest Peninsular. També s'ofereix una reflexió des de l'experiència respecte al potencial i las limitacions d'aquesta mena d'investigació.
Strain localization and fracture in isotropic damaging materials: a novel augmented-finite element strategy

The assignment of powers in an open-ended European Union
2003
Presented at CESIFO Conference “A Constitution for the EU”, February 2003; International audience; A major characteristic of the European Union is its transitional or evolving nature, in particular with regard to the assignment of powers between the two main levels of government. More precisely, under current constitutional arrangements, this evolving nature takes the form of an integration process which tends to be monotonous, that is, which can only with great difficulty be reversed. The paper is mainly devoted to the explanation of how this comes about and what effects this has on other features of the process. As a concluding remark, however, it suggests that an additional criterion for…
Horizontal competition in multilevel governmental settings
2013
28 pages; Governments situated on the same level of a multi-level governmental system compete with each other as well as with governments placed higher or lower. This paper is concerned with horizontal competition only. It discusses both competition based on the mobility of agents and competition based on comparisons of performance across jurisdictions - i.e., yardstick competition. With regard to the first kind, the focus is on the capacity of governments and voters to decide policies in spite of the mobility of agents. Some attention is also given to non-standard mechanisms in which mobility is manipulated so as to change the structure of the electorate. The paper considers two forms of h…
How significant is yardstick competition among governments? Three reasons to dig deeper
2013
22 pages; The significance of yardstick competition among governments is now confirmed with regard to fiscal variables. This is an important result but the significance of the mechanism must also be sought in a context broader than that of fiscal federalism and without limitation to relations and processes fully observable. Three points are made. Even in the case of governments trying to mimic each other over a single variable, additional variables are involved in an important way. Yardstick competition can be latent without being ineffective. Its major effect, then, is to set bounds to the choices that office-holders could think of making. Finally, the mechanism is a hidden albeit essentia…
