Governance in the metropolitan area of Valencia (Spain): an unfinished business
2023
Metropolitan government is still an unfinished business in Spain. An example of this is the metropolitan area of Valencia. The aim of this article is to learn about the process that has led to the current situation of a lack of metropolitan government and to propose actions that will help to make it a reality in the not-too-distant future. To this end, it analyses the history and the current regulations, and it is completed with the opinions and contributions of academics and politicians. The result is that, although there is no political will to include the consolidation of a metropolitan government in Valencia in the current political agenda, it is possible to set in motion initiatives of…
Analysis of the Autism Spectrum Disorder (ASD) Knowledge of Cuban Teachers in Primary Schools and Preschools
2022
Teachers’ knowledge of autism spectrum disorder (ASD) plays a key role in the successful inclusion of children with ASD in regular schools. The objective of this study was to analyze Cuban teachers’ knowledge of ASD of at inclusive primary schools and preschools and to compare it with the results obtained in previous studies carried out at an international level. To do this, a cross-sectional study was conducted with Cuban teachers from urban and rural areas throughout the country. The sample was selected using a non-probabilistic technique. In total, 131 primary school and preschool teachers participated. Data were collected by applying the Autism Knowledge Questionnaire (AKQ) …
CQ*-Algebras of Operators and Application to Quantum Models
2000
C*-algebras constitute, as known, the cornerstones of the Haag-Kastler [1] algebraic approach to quantum systems, with infinitely many degrees of freedom: one usually starts, in fact, with associating to each bounded region V of the configuration space of the system the C*-algebra A v of local observables in V. The uniform completion A of the algebra A0 generated by the Av’s is then considered as the C*-algebra of observables of the system.
Stability of Hamiltonian Systems of Two Degrees of Freedom and of Formally Conservative Mappings Near a Singular Point
1985
We restrict ourselves to the stability problems considered in our lecture because the length of this paper is limited. In contrast to the lecture, however, we consider here not only area preserving mappings but a more general class of mappings.
Remark on integrable Hamiltonian systems
1980
An extension ton degrees of freedom of the fact is established that forn=1 the time and the energy constant are canonically conjugate variables. This extension is useful in some cases to get action-angle variables from the general solution of a given integrable Hamiltonian system. As an example the Delaunay variables are proved to be canonical.
The KAM Theorem
2016
This theorem guarantees that, under certain assumptions, in the case of a perturbation \(\varepsilon H_{1}(\boldsymbol{J},\boldsymbol{\theta })\) with small enough ɛ, the iterated series for the generator W(θ i 0, J i ) converges (according to Newton’s procedure) and thus the invariant tori are not destroyed. The KAM theorem is valid for systems with two and more degrees of freedom. However, in the following, we shall deal exclusively with the case of two degrees of freedom.
Unifying vectors and matrices of different dimensions through nonlinear embeddings
2020
Complex systems may morph between structures with different dimensionality and degrees of freedom. As a tool for their modelling, nonlinear embeddings are introduced that encompass objects with different dimensionality as a continuous parameter $\kappa \in \mathbb{R}$ is being varied, thus allowing the unification of vectors, matrices and tensors in single mathematical structures. This technique is applied to construct warped models in the passage from supergravity in 10 or 11-dimensional spacetimes to 4-dimensional ones. We also show how nonlinear embeddings can be used to connect cellular automata (CAs) to coupled map lattices (CMLs) and to nonlinear partial differential equations, derivi…
[Clinical guidelines for the management of gastrointestinal stromal tumors]
2006
Treatment of gastrointestinal stromal tumors (GIST) has been revolutioned by the recently discovered molecular mechanism responsible for the oncogenesis of this disease. In addition, due to the rapid progress at molecular and clinical level observed in the last few years, there is a need to review the current state of the art in order to delineate appropriate guidelines for the optimal management of these tumors. A panel of experts from several specialities, including medical oncology, surgery, pathology, molecular biology and imaging, were invited to participate in a meeting to present and discuss a number of pre-selected questions, and to achieve a consensus according to the categories of…
The era of reference genomes in conservation genomics
2022
Progress in genome sequencing now enables the large-scale generation of reference genomes. Various international initiatives aim to generate reference genomes representing global biodiversity. These genomes provide unique insights into genomic diversity and architecture, thereby enabling comprehensive analyses of population and functional genomics, and are expected to revolutionize conservation genomics.
Insula, vincoli e preesistenze. L'insula "0E" e il Cortile Gnazziddi
2012
La scheda descrive uno dei dodici temi di progetto del Prin 2007. In particolare, tratteggia le questioni relative al margine sud-est del quartiere Zen, rimasto incompleto per accogliere un vincolo della Soprintendenza.
