Oscillations of the purity in the repeated-measurement-based generation of quantum states
2008
Repeated observations of a quantum system interacting with another one can drive the latter toward a particular quantum state, irrespectively of its initial condition, because of an {\em effective non-unitary evolution}. If the target state is a pure one, the degree of purity of the system approaches unity, even when the initial condition of the system is a mixed state. In this paper we study the behavior of the purity from the initial value to the final one, that is unity. Depending on the parameters, after a finite number of measurements, the purity exhibits oscillations, that brings about a lower purity than that of the initial state, which is a point to be taken care of in concrete appl…
Hierarchy and dynamics of trace distance correlations
2013
We define and analyze measures of correlations for bipartite states based on trace distance. For Bell diagonal states of two qubits, in addition to the known expression for quantum correlations using this metric, we provide analytic expressions for the classical and total correlations. The ensuing hierarchy of correlations based on trace distance is compared to the ones based on relative entropy and Hilbert-Schmidt norm. Although some common features can be found, the trace distance measure is shown to differentiate from the others in that the closest uncorrelated state to a given bipartite quantum state is not given by the product of the marginals, and further, the total correlations are s…
Fundacje zakładane przez osoby prawne kościoła katolickiego w Polsce a fundacje pobożne
2013
Przedmiotem artykułu jest analiza statusu prawnego fundacji zakładanych przez osoby prawne Kościoła katolickiego, o których mowa w art. 26 konkordatu między Stolicą Apostolską i Rzecząpospolitą Polską z 1993 r. i art. 58 ustawy z dnia 17 maja 1989 r. o stosunku Państwa do Kościoła Katolickiego w Rzeczypospolitej Polskiej (fundacje kościelne) oraz pobożnych fundacji, o których mowa w przepisach Kodeksu Prawa Kanonicznego z 1983 r. Ponadto w artykule poruszono zagadnienie wpływu systemu prawa polskiego i systemu prawa kanonicznego na działalność wymienionych fundacji. Przeprowadzone analizy prowadzą do wniosku, że fundacje zakładane przez osoby prawne Kościoła katolickiego na forum państwowym…
[Evolution and scientific impact of research grants from the spanish society of cardiology and spanish heart foundation (2000-2006)].
2011
Abstract Introduction and objectives The Sociedad Espanola de Cardiologia (Spanish Society of Cardiology) every year awards grants to finance research in the field of cardiovascular diseases. The aim of this study is to identify the impact of these investments during the period 2000-2006 from the subsequently published articles in scientific journals. Methods Using the identifying data of each project as search terms, all articles that resulted from these grants were located in the Spanish Indice Medico Espanol and Indice Bibliografico Espanol en Ciencias de la Salud databases, and in Science Citation Index-Expanded and Scopus. Descriptive statistical analysis of these articles included typ…
Some basic theorems on the foundations of mathematics and their philosophical implications
1995
Research in the foundations of mathematics during the past few decades has produced some results, which seem to me of interest, not only in themselves, but also with regard to their implications for the traditional philosophical problems about the nature of mathematics. The results themselves, I believe, are fairly widely known, but nevertheless, I think, it will be useful to present them in outline once again, especially in view of the fact that, due to the work of various mathematicians, they have taken on a much more satisfactory form, than they had had originally. The greatest improvement was made possible through the precise definition of the concept of finite procedure, which plays a …
Central Themes and Impact of Pieri’s Work
2021
The first book of this series, The Legacy of Mario Pieri in Geometry and Arithmetic (cited here as M&S 2007), presented an overview of Pieri’s life and research, and a deeper study of the background of his work in foundations of geometry and arithmetic.
L'Islam di fronte e attraverso
2020
Il volume raccogliei testi delle lezioni introduttive di Cultura islamica tenutesi a Mazara del Vallo nel 2019 con l'intento di proporre al lettore degli argomenti di livello scientifico ma di carattere divulgativo. La cornice è quella di un contesto che desidera far conoscere e tenere vivo un antico legame con gli abitanti giunti da una sponda che non si vuole definire "opposta", ma piuttosto transfrontaliera e che quotidianamente ci attraversa e con noi si interseca. The volume collects the texts of the introductory lessons of Islamic culture held in Mazara del Vallo in 2019 with the aim of proposing to the reader topics of a scientific level but informative. The frame is that of a contex…
Understanding the Microfoundations of Entrepreneurial Ecosystems: Toward a Value-Based Method and Theory
2023
Despite the progress made by scholars, empirically investigating entrepreneurial ecosystems (EEs) remains problematic because of the inherent complexities and nonlinearities of interactions among EE actors. The research to date has shown a tendency to focus on macrolevel ecosystem dynamics while neglecting the microfoundations of EEs. We contend that this negligence is due to a lack of appropriate methodologies that can capture EE microfoundations through a systemic value-based perspective. To fill this gap, in this article, we propose a novel methodological approach, the value system method, which enables framing EEs through critical causal interdependences between key actors’ business mod…
Inside-out Internal and External Limits to Rights: Does it matter?
2019
Literature is rich on whether and how rights are limited by external considerations, such as other rights or particularly important general interests. This article concentrates on what could be a different type of limit of rights: internal limits stemming from the very foundations of a right. Its aim is to understand whether these hypothetically different internal limits actually collapse on the idea of internal limits of coherence theories; or whether they are equivalent, in terms of effects, to external limits to rights. In order to show the origin of the troubling with internal limits, the article begins with a brief introduction of biocultural rights of indigenous peoples and local com…
El protagonismo de las fundaciones americanas en la institucionalización de la sociología (1945-1960)
2001
Este artículo expone el protagonismo que desempeñaron las fundaciones Rockefeller, Carnegie y Ford en la institucionalización de la sociología después de la Segunda Guerra Mundial. Estas instituciones han tenido grandes cantidades de dinero a su disposición y la mayor parte del trabajo empírico en ciencias sociales sólo se puede llevar a cabo si hay dinero disponible para cubrir sus gastos. Pero, ¿quiénes se beneficiaron de estas ayudas en Europa y Estados Unidos? El dinero público y privado ha desempeñado un papel significativo y cada vez mayor en el desarrollo de la sociología, pero cabe también preguntarse cómo ha afectado a la investigación el origen de este dinero. La Ford, por ejemplo…
