Local spectral theory for Drazin invertible operators
2016
Abstract In this paper we investigate the transmission of some local spectral properties from a bounded linear operator R, as SVEP, Dunford property (C), and property (β), to its Drazin inverse S, when this does exist.
PreGarside monoids and groups, parabolicity, amalgamation, and FC property
2012
We define the notion of preGarside group slightly lightening the definition of Garside group so that all Artin–Tits groups are preGarside groups. This paper intends to give a first basic study on these groups. Firstly, we introduce the notion of parabolic subgroup, we prove that any preGarside group has a (partial) complemented presentation, and we characterize the parabolic subgroups in terms of these presentations. Afterwards we prove that the amalgamated product of two preGarside groups along a common parabolic subgroup is again a preGarside group. This enables us to define the family of preGarside groups of FC type as the smallest family of preGarside groups that contains the Garside g…
T cell-independent joint destruction
1998
Rheumatoid Arthritis (RA) is a chronic systemic disorder of unknown etiology. Although, early and late stages of the disease may be driven by different processes, affected joints are characterized by inflammation, synovial hyperplasia, and abnormal immune responses [1]. The abundance of T cells within the rheumatoid synovium as well as the association of certain major histocompatibility complex (MHC) class II molecules with RA [2] implied a central role for T cells in the pathophysiology of the disease. However, recent advances in molecular biology have fostered new concepts for the pathogenesis of RA. Specifically, the investigation of early stages of disease, the development of novel anim…
The Attention Schema Theory: A Foundation for Engineering Artificial Consciousness
2017
The purpose of the attention schema theory is to explain how an information-processing device, the brain, arrives at the claim that it possesses a non-physical, subjective awareness, and assigns a high degree of certainty to that extraordinary claim. The theory does not address how the brain might actually possess a non-physical essence. It is not a theory that deals in the non-physical. It is about the computations that cause a machine to make a claim and to assign a high degree of certainty to the claim. The theory is offered as a possible starting point for building artificial consciousness. Given current technology, it should be possible to build a machine that contains a rich internal …
Neural network approach to solving fuzzy nonlinear equations using Z-numbers
2020
In this article, the fuzzy property is described by means of the Z-number as the coefficients and variables of the fuzzy equations. This alteration for the fuzzy equation is appropriate for system modeling with Z-number parameters. In this article, the fuzzy equation with Z-number coefficients and variables is tended to be used as the models for the uncertain systems. The modeling issue related to the uncertain system is to obtain the Z-number coefficients and variables of the fuzzy equation. Nevertheless, it is extremely hard to get the Z-number coefficients of the fuzzy equations. In this article, in order to model the uncertain nonlinear systems, a novel structure of the multilayer neura…
Property (w) under compact or Riesz perturbations
2010
Si studia la permanenza della proprietà (w), una variante del Teorema di Weyl, nel caso che un operatore sia perturbato da un operatore compatto oppure di Riesz
The role of Intellectual Property Rights in the value capturing of crowdsourcing for innovation contests
2017
In this study, we investigate the role of IPR arrangements in crowdsourcing for innovation challenges. Integrating Property Rights Theory and the open innovation literature, we propose that specific challenge attributes affect the seekers organizations’ choice between alternative IPR arrangements and how this choice, in turn, affects the self-selection of external solvers into solving the challenge. We collected multi-source, interview data with open innovation directors and we built a unique data set of 729 awarded challenges broadcasted on InnoCentive platform from 2010 to 2016. Our findings contribute to the emerging literature on open innovation and crowdsourcing literature by bringing …
LAND AND PROPERTY RIGHTS WITHIN THE URBANISM LAW
2017
The study intends to highlight the functions of property rights in relation to the characteristics of urbanism law. The analyse aims to identify the role of public authorities in the production process of planning public policies, under current regulations in force in Romania. Moreover, while the legislation led to confer a social function of property rights, this conception of property rights comes up against the revival of private property, which is likely to complicate the implementation of public planning policies. The social function of the property law, however, could reach its limits in the coming years. Indeed, the jurisprudence appears to give a boost to the individualistic dimensi…
Quantum Algorithm for Distribution-Free Junta Testing
2019
Inspired by a recent classical distribution-free junta tester by Chen, Liu, Serverdio, Sheng, and Xie (STOC’18), we construct a quantum tester for the same problem with complexity \(O(k/\varepsilon )\), which constitutes a quadratic improvement.
Quantum Dual Adversary for Hidden Subgroups and Beyond
2019
An explicit quantum dual adversary for the S-isomorphism problem is constructed. As a consequence, this gives an alternative proof that the query complexity of the dihedral hidden subgroup problem is polynomial.
