Physical applications of algebras of unbounded operators
2007
During the past 20 years a long series of papers concerning algebras of unbounded operators appeared in the literature, papers which, though being originally motivated by physical arguments, contain almost no physics at all. On the contrary the mathematical aspects of these algebras have been analyzed in many details and this analysis produced, up to now, the monographes [32] and [2]. Some physics appeared first in [28] and [31], in the attempt to describe systems with a very large (1024) number of degrees of freedom, following some general ideas originally proposed in the famous Haag and Kastler’s paper, [27], on QM∞.
New Twists of 3D Chiral Metamaterials
2018
Rationally designed artificial materials, called metamaterials, allow for tailoring effective material properties beyond ("meta") the properties of their bulk ingredient materials. This statement is especially true for chiral metamaterials, as unlocking certain degrees of freedom necessarily requires broken centrosymmetry. While the field of chiral electromagnetic/optical metamaterials has become rather mature, the field of elastic/mechanical metamaterials is just emerging and wide open. This research news reviews recent theoretical and experimental progress concerning 3D chiral mechanical and optical metamaterials, with special emphasis on work performed at KIT.
Retrieval of atmospheric CH4profiles from Fourier transform infrared data using dimension reduction and MCMC
2016
We introduce an inversion method that uses dimension reduction for the retrieval of atmospheric methane (CH4) profiles. Uncertainty analysis is performed using the Markov chain Monte Carlo (MCMC) statistical estimation. These techniques are used to retrieve CH4 profiles from the ground-based spectral measurements by the Fourier Transform Spectrometer (FTS) instrument at Sodankyla (67.4 degrees N, 26.6 degrees E), Northern Finland. The Sodankyla FTS is part of the Total Carbon Column Observing Network (TCCON), a global network that observes solar spectra in near-infrared wavelengths. The high spectral resolution of the data provides approximately 3 degrees of freedom about the vertical struc…
Freedom and Redistribution
2012
In this paper we study the determinants of peopleís attitudes toward income inequality and their economic consequences. We argue that an individualís atti- tudes toward inequality depend upon the extent of freedom of choice and control over life outcomes he enjoys. We construct a two-stage empirical model where people Örst choose the level of income transfers and then their optimal level of ef- fort. We Önd that the higher the extent of an individualís free choice and control over life outcomes, the greater the probability that he supports larger income di§erences as incentives for individual e§ort. We also show that this relationship determines important consequences for the individualís w…
Protection of the right to freedom of assembly and association under ECHR: compliance difficulties in Azerbaijan
2018
The protection of the right to freedom of peaceful assembly and association under the ECHR and compliance difficulties in Azerbaijan, regarding these rights are discussed in this master thesis. The protection of the right to freedom of peaceful assembly and association is one of the critical elements for the development of democracy, and these rights are protected by international documents such as the European Convention for the Protection of Human Rights and Fundamental Freedoms (hereinafter referred as the European Convention on Human Rights or the ECHR). Furthermore, the protection of these rights at national level must be compatible with the standards of the Council of Europe. The impo…
Tensions and expression in Milos Forman’s American films
2012
Milos Forman’s American films require a plural outlook. The director has always been drawn to stories of conflicts that are essential, according to him, to study human passion. This tension, thematic as well as esthetic, allows him to show the smallest mechanisms that lead to oppression in European and American stories, providing the viewer with a lesson of anatomy that pinpoints the most invisible magnetic forces leading to power. This course is accompanied by a journey to individualism, through forces involved in the identification with attractive though realistic characters, through the rediscovery of individual freedom within primitive or regressive worlds, insisting on the necessity of…
L’ambiguïté de la condition humaine et ses interprétations existentialistes selon Simone de Beauvoir
2018
Simone de Beauvoir perceives existentialism as a philosophy of ambiguity, suggesting that a man should reconcile the contradictions of the human condition. The philosophical essays of the author show the evolution of her thinking. Beauvoir discovers the paradoxes of existentialism, mainly the antimony between responsibility and powerlessness of an individual. Her work captures an image of reality while relativizing philosophical values and maintaining the opposites. Her texts show the ambivalent attitude of the author to existence. Thus, they reflect her point of view, according to which moral consciousness only exists when a person experiences some intellectual dissonance or a sense of fai…
La sentenza della Grande Camera della Corte europea dei diritti umani nel caso S.A.S. c. Francia: una 'sentenza-monito', ma di che tipo?
2015
L'articolo commenta la sentenza S.A.S. c. Francia in cui la Corte EDU ha stabilito che la legge francese 2010-1192, che proibisce la coperura del viso in tutti i luoghi pubblici, non viola il diritto delle donne di religione musulmana di indossare il burqa e il Niqab. Il commento si concentra in particolare sulla questione del valore giuridico che può essere atttribuito ad alcuni "moniti" che la Corte indirizza alla Francia in questa sentenza, i quali sembrano difficilmente collocabili nel solco della precedente giurisprudenza della Corte. In the judgment S.A.S. versus France the ECtHR held that the French law «prohibiting the concealment of one’s face in public spaces» does not violate the…
Modeling of biomolecular machines in non-equilibrium steady states
2021
Numerical computations have become a pillar of all modern quantitative sciences. Any computation involves modeling--even if often this step is not made explicit--and any model has to neglect details while still being physically accurate. Equilibrium statistical mechanics guides both the development of models and numerical methods for dynamics obeying detailed balance. For systems driven away from thermal equilibrium such a universal theoretical framework is missing. For a restricted class of driven systems governed by Markov dynamics and local detailed balance, stochastic thermodynamics has evolved to fill this gap and to provide fundamental constraints and guiding principles. The next step…
Improving the QM/MM Description of Chemical Processes: A Dual Level Strategy To Explore the Potential Energy Surface in Very Large Systems.
2005
Potential energy surfaces are fundamental tools for the analysis of reaction mechanisms. The accuracy of these surfaces for reactions in very large systems is often limited by the size of the system even if hybrid quantum mechanics/molecular mechanics (QM/MM) strategies are employed. The large number of degrees of freedom of the system requires hundreds or even thousands of optimization steps to reach convergence. Reactions in condensed media (such as enzymes or solutions) are thus usually restricted to be analyzed using low level quantum mechanical methods, thus introducing a source of error in the description of the QM region. In this paper, an alternative method is proposed, coupled to t…
