Multilevel Power Relations and Planning Conflicts in a ‘Land of Exception’: The Case of the Sughereta di Niscemi Reserve in Sicily
2019
This article aims to investigate how the asymmetrical (political and economic) power relations can influence the effectiveness of planning systems at the local governance level, producing conflicting forms between land transformation and protection of natural interest sites. The article demonstrates how this condition can generate severe forms of environmental and social injustice through the case study of the M.U.O.S. of Niscemi (Mobile User Objective System). M.U.O.S. of Niscemi is a ground station for military communications satellite system, constructed by the United States Navy (Department of Defense) in Zone B of the natural reserve of "Sughereta di Niscemi" (the most relevant relict …
Management and Control of the Read Out Processors (tpps) of the Aleph Time Projection Chamber
1989
The readout of the Aleph time projection chamber (TPC) relies on a set of 72 time projection processors (TPPs), which are based on a Motorola 68020 microprocessor running a real-time operating system. The advanced processing capabilities of the TPPs allow them to perform in parallel a number of tasks, both during and outside of data acquisition, which are outlined. The management and control of such a large number of intelligent devices is presented. The discussion covers the hardware configuration of the TPPs; the software running the TPPs; their management, status, and control; exception handling and message logging; and the TPP monitoring tasks. >

Phenomenology in Ortega and in Zubiri
2002
Jose Ortega y Gasset (1883–1955) and Xavier Zubiri (b. 1898) represent an exceptional point in the reception and assimilation of phenomenology in Spain. There can be no possible contextualization of Ortega’s and Zubiri’s thought outside its connections with phenomenology.1
Exceptional points in a non-Hermitian extension of the Jaynes-Cummings Hamiltonian
2016
We consider a generalization of the non-Hermitian \({\mathcal PT}\) symmetric Jaynes-Cummings Hamiltonian, recently introduced for studying optical phenomena with time-dependent physical parameters, that includes environment-induced decay. In particular, we investigate the interaction of a two-level fermionic system (such as a two-level atom) with a single bosonic field mode in a cavity. The states of the two-level system are allowed to decay because of the interaction with the environment, and this is included phenomenologically in our non-Hermitian Hamiltonian by introducing complex energies for the fermion system. We focus our attention on the occurrence of exceptional points in the spec…
Model pseudofermionic systems: Connections with exceptional points
2014
We discuss the role of pseudo-fermions in the analysis of some two-dimensional models, recently introduced in connection with non self-adjoint hamiltonians. Among other aspects, we discuss the appearance of exceptional points in connection with the validity of the extended anti-commutation rules which define the pseudo-fermionic structure.
Il principio del non refoulement tra controllo dell'accesso al territorio dell'Unione europea e protezione dei diritti umani
2020
Nonostante il non-refoulement sia un principio cardine del diritto internazionale dei rifugiati, il suo preciso ambito di applicazione e l’esatta individuazione degli obblighi a carico degli Stati sono oggetto di incertezza per la tensione costante tra due opposte tendenze. In quanto espressione di un valore umanitario fondamentale, sono fiorite interpretazioni estensive, ma, in quanto limite al potere sovrano dello Stato di regolare l’accesso al territorio, sono emerse tendenze di segno restrittivo. L’articolo presenta la politica comune di asilo come sottoposta alla stessa tensione e ne descrive per grandi linee gli aspetti che costituiscono un ampliamento della protezione offerta dal dir…

Characterization of the atmospheric muon flux in IceCube
2015
Muons produced in atmospheric cosmic ray showers account for the by far dominant part of the event yield in large-volume underground particle detectors. The IceCube detector, with an instrumented volume of about a cubic kilometer, has the potential to conduct unique investigations on atmospheric muons by exploiting the large collection area and the possibility to track particles over a long distance. Through detailed reconstruction of energy deposition along the tracks, the characteristics of muon bundles can be quantified, and individual particles of exceptionally high energy identified. The data can then be used to constrain the cosmic ray primary flux and the contribution to atmospheric …
