Electron structure, ultra-dense hydrogen and low energy nuclear reactions
2019
In this paper, a simple Zitterbewegung electron model, proposed in a previous work, is presented from a different perspective based on the principle of mass- frequency equivalence. A geometric- electromagnetic interpretation of mass, relativistic mass, De Broglie wavelength, Proca, Klein- Gordon, Dirac and Aharonov- Bohm equations in agreement with the model is proposed. A non-relativistic, Zitterbewegung interpretation of the 3.7 keV deep hydrogen level found by J. Naudts is presented. According to this perspective, ultra-dense hydrogen can be conceived as a coherent chain of bosonic electrons with protons or deuterons located in the center of their Zitterbewegung orbits. This approach sug…
Medical image registration: Interpolations, similarities and optimizations strategies
2010
This paper presents a study conducted for evaluating different interpolation schemes, similarity metrics and optimization algorithms for the purpose of volumetric medical image registration. Each technique has been implemented to be plugged in a modular system. Rotation, translation and scale error has been measured to obtain a performance evaluation for all of the combinations of the considered techniques. Several experimental tests were conducted for validation both on synthetic and real datasets providing an exhaustive overview of the various strategies used.
Comprehensive Uncertainty Management in MDPs
2013
Multistage decision-making in robots involved in real-world tasks is a process affected by uncertainty. The effects of the agent’s actions in a physical en- vironment cannot be always predicted deterministically and in a precise manner. Moreover, observing the environment can be a too onerous for a robot, hence not continuos. Markov Decision Processes (MDPs) are a well-known solution inspired to the classic probabilistic approach for managing uncertainty. On the other hand, including fuzzy logics and possibility theory has widened uncertainty representa- tion. Probability, possibility, fuzzy logics, and epistemic belief allow treating dif- ferent and not always superimposable facets of unce…
Introduzione. Quel che accade nel Mediterraneo centrale come emblema del lato oscuro del diritto
2021
Il contributo introduce lo special Issue "Il lato oscuro del diritto nella criminalizzazione del soccorso in mare" sottolineando come le ricostruzioni e le riflessioni poste in essere in questa raccolta di contributi possano almeno contribuire a descrivere le dinamiche e a porre in evidenza i pericoli intrinseci nello spazio di arbitrio che il lato oscuro del diritto schiude. Argomenta inoltre perché ciò sia possibile proprio a partire dal contesto tanto specifico quanto urgente preso in considerazione, poiché nel Mediterraneo centrale la lotta per il diritto, spesso giocata proprio a partire dai chiaroscuri delle norme, si traduce ogni giorno in vite perdute o vite salvate.
Il costituzionalismo contemporaneo ai tempi del Covid-19
2020
L’indeterminatezza è una delle caratteristiche salienti del diritto negli stati costituzionali contemporanei. Tale caratteristica mette in crisi le concezioni “oggettualistiche” del diritto che riducono il diritto a un insieme di norme o a un insieme di fatti e corrobora quelle concezioni che considerano il diritto una pratica sociale interpretativa. La costituzionalizzazione degli ordinamenti giuridici accresce la flessibilità del diritto a detrimento della certezza e impone a tutti – legislatori, giudici e individui soggetti al diritto – di assumersi le proprie responsabilità e i rischi che ne conseguono. Il modo in cui il legislatore, a diversi livelli, fronteggia l’attuale pandemia da C…
POSITIVISMO JURÍDICO NORMATIVO, NEUTRALIDAD Y ESTADO DE DERECHO
2012
Usually, in jurisprudential debates what is discussed under the rubric of ‘neutrality’ is the claim that jurisprudence is (or at least can, and should be) a conceptual, or descriptive - thus, non-normative, or morally neutral - inquiry. I discuss neutrality in an altogether different sense, namely, neutrality as an ethico-political ideal the law should meet. My starting point is normative legal positivism, or the claim that it is a good and desirable thing that the laws have easily identifiable, readily accessible, as far as possible non-controversial social sources. What justifies normative legal positivism, I claim, is the value - or the ideal - of neutrality, suitably understood. I.e., w…
Law as Power: Two Rule of Law Requirements
2013
Abstract. ‘Law as power’ is a neglected topic in contemporary analytical jurisprudence. Attention has been paid, from Hart (and Kelsen) onwards, to normative powers. ‘Brute’ social power, however, and law’s relation to it, are, in post-Hartian jurisprudence, largely overlooked. The subject of this paper is the shape social power takes when the rule of the law is envisaged as an ethico-political ideal—I discuss, that is, the Rule of Law as a specific mode of the exercise of social power, and what is valuable in it. I concentrate on two Rule of Law requirements, consistency (i.e., the avoidance of conflicts) and compliability (i.e., conformity to the ‘ought’ implies ‘can’ principle). They con…
Lo stato costituzionale di fronte all’emergenza pandemica
2022
La costituzionalizzazione degli ordinamenti giuridici accresce la flessibilità del diritto a detrimento della certezza e impone a tutti – legislatori, giudici e individui soggetti al diritto – di assumersi le proprie responsabilità e i rischi che ne conseguono. Il modo in cui il legislatore, a diversi livelli, fronteggia l’attuale pandemia da Covid-19 costituisce un interessante angolo visuale per riflettere sugli effetti – alcuni positivi, altri negativi – prodotti dall’indeterminatezza del diritto contemporaneo. Legal systems’ constitutionalization increases legal flexibility at the expense of legal certainty; it imposes to legislators, judges and individuals the responsibility and the as…
L’insostenibile leggerezza dell’incertezza del diritto
2020
The paper deals with the structural vagueness of the legal measures enacted by the Italian legislator to manage the Covid-19 pandemic. Can we demand more certain norms? Is personal liberty taken in due account by the legislator? Starting from these and similar questions, the paper proposes a reconstruction of the law and of the underlying legal ideology of contemporary constitutional States.
Agamennone βουληφόρος? La sovranità alla prova del processo deliberativo
2022
Starting with the Iliad, Agamemnon is mostly depicted at the centre of dramatic deliberative situations. This feature is also present in fifth-century literature, particularly in some plays in which Agamemnon’s decision-making ability in uncertainty comes into tension with other characters in order to determine the ‘right’ decision and adequate leadership features. In this paper, I will focus on the Euripides’ play Iphigenia in Aulis (405 a.C.). In this tragedy the behaviour of the Achaean king draws our attention, as he is not equipped to handle his role and responsibilities. In the same years, also historiography is interested in the nature and risks of the deliberative process, as Thucyd…
