description: Hundreds of stellar-mass black holes likely form in a typical globular star cluster, with all but one predicted to be ejected through dynamical interactions. Some observational support for this idea is provided by the lack of X-ray-emitting binary stars comprising one black hole and one other star ("black-hole/X-ray binaries") in Milky Way globular clusters, even though many neutron-star/X-ray binaries are known. Although a few black holes have been seen in globular clusters around other galaxies, the masses of these cannot be determined, and some may be intermediate-mass black holes that form through exotic mechanisms. Here we report the presence of two flat-spectrum radio sources in the Milky Way globular cluster M22, and we argue that these objects are black holes of stellar mass (each ~ 10-20 times more massive than the Sun) that are accreting matter. We find a high ratio of radio-to-X-ray flux for these black holes, consistent with the larger predicted masses of black holes in globular clusters compared to those outside. The identification of two black holes in one cluster shows that the ejection of black holes is not as efficient as predicted by most models, and we argue that M22 may contain a total population of ~ 5-100 black holes. The large core radius of M22 could arise from heating produced by the black holes.

description: We derive a class of energy preserving boundary conditions for incompressible Newtonian flows and prove local-in-time well-posedness of the resulting initial boundary value problems, i.e. the Navier-Stokes equations complemented by one of the derived boundary conditions, in an Lp-setting in domains, which are either bounded or unbounded with almost flat, sufficiently smooth boundary. The results are based on maximal regularity properties of the underlying linearisations, which are also established in the above setting.

description: L’articolo evidenzia l’importanza di due fattori, finora trascurati, nel processo di formazione dell’indipendentismo catalano agli inizi del secolo scorso: da un lato l’influenza decisiva della repressione sullo sviluppo e la caratterizzazione di questo movimento, soprattutto dopo gli eventi di ¡Cu-cut! del novembre 1905; dall’altro l’importante ruolo di un gruppo di catalani residenti a Cuba nell’apparizione, nell’ottobre del 1906, delle prime e più esplicite rivendicazioni a favore dell’indipendenza della Catalogna. This article focuses on the relevance of two underestimated factors in the formation of the Catalan independence movement of at the beginning of last century: on the one hand the decisive influence of repression on the development and the consequent characterization of this movement, especially after the so-called “events of ¡Cu-cut!” in November 1905; on the other, the role of a group of Catalan residents in Cuba on the appearance, in October 1906, of the first and more explicit claims of independence for Catalonia.

description: In the field of empirical modeling using Genetic Programming (GP), it is important to evolve solution with good generalization ability. Generalization ability of GP solutions get affected by two important issues: bloat and over-fitting. We surveyed and classified existing literature related to different techniques used by GP research community to deal with these issues. We also point out limitation of these techniques, if any. Moreover, the classification of different bloat control approaches and measures for bloat and over-fitting are also discussed. We believe that this work will be useful to GP practitioners in following ways: (i) to better understand concepts of generalization in GP (ii) comparing existing bloat and over-fitting control techniques and (iii) selecting appropriate approach to improve generalization ability of GP evolved solutions.

description: Globally, the importance of sustainable development is recognized due to a number of interconnected social, environmental, and economic challenges. One of the key tenets of sustainable development is the introduction of clean energy, and specifically renewable energy technologies (RETs). To accelerate the adoption of RETs, however, requires the rate of commercialization of such technologies to increase; classified as multitechnology renewable energy systems (MTRESs) due to the hierarchical nature of such systems, with differing commercialization-based needs. A strategic management framework was subsequently developed as a means to support the establishment of strategies for increasing the commercialization rate of MTRESs, and applied to the case of concentrating solar power in South Africa. The framework serves as a proof-of-concept, given the current industry constraints due to political uncertainties in the energy sector of the country, as well as the type of validation process followed, with the framework yet to be practically implemented. This article encourages dialogue on how different stakeholders may be mobilized in the interests of a given technology, while continuing a recent trend in literature, which seeks to move the conversation from energy analysis to practical measures, aimed at hastening efforts towards a sustainable energy transition.
Classically Scale-invariant B-L Model and Conformal Gravity

description: We consider a coupling of conformal gravity to the classically scale-invariant B-L extended standard model which has been recently proposed as a phenomenologically viable model realizing the Coleman-Weinberg mechanism of breakdown of the electro-weak symmetry. As in a globally scale-invariant dilaton gravity, it is also shown in a locally scale-invariant conformal gravity that without recourse to the Coleman-Weinberg mechanism, the B-L gauge symmetry is broken in the process of spontaneous symmetry breakdown of the local scale invariance (Weyl invariance) at the tree level and as a result the B-L gauge field becomes massive via the Higgs mechanism. As a bonus of conformal gravity, the massless dilaton field does not appear and the parameters in front of the non-minimal coupling of gravity are completely fixed in the present model. This observation clearly shows that the conformal gravity has a practical application even if the scalar field does not possess any dynamical degree of freedom owing to the local scale symmetry.

description: We study a class of SU(N) Heisenberg models, describing Mott insulators of fermionic ultra-cold alkaline earth atoms on the three-dimensional simple cubic lattice. Based on an earlier semiclassical analysis, magnetic order is unlikely, and we focus instead on a solvable large-N limit designed to address the competition among non-magnetic ground states. We find a rich phase diagram as a function of the filling parameter k, composed of a variety of ground states spontaneously breaking lattice symmetries, and in some cases also time reversal symmetry. One particularly striking example is a state spontaneously breaking lattice rotation symmetry, where the cubic lattice breaks up into bilayers, each of which forms a two-dimensional chiral spin liquid state.

description: We report on Bloch-Zener oscillations of an ultracold Fermi gas in a tunable honeycomb lattice. The quasi-momentum distribution of the atoms is measured after sequentially passing through two Dirac points. We observe a double-peak feature in the transferred fraction to the second band, both as a function of the band gap at the Dirac points and the quasi-momentum of the trajectory. Our results are in good agreement with a simple analytical model based on two successive Landau-Zener transitions. Owing to the variation of the potential gradient over the cloud size, coherent Stückelberg oscillations are not visible in our measurements. This effect of the harmonic confinement is confirmed by a numerical simulation of the dynamics of a trapped 2D system.

description: Pair production of light top squarks at the 8-TeV LHC can be used to probe the gaugino-Higgsino sector of the Minimal Supersymmetric Standard Model. The case where the lightest neutralino is a mixture of Bino and Higgsino, satisfying the thermal dark matter relic density, is investigated. In such a scenario, the lightest top squark decays mostly into $(i)$ a top quark plus the second or third lightest neutralino, and $(ii)$ a bottom quark plus the lightest chargino, instead of a decay scenario of the lightest top squark into a top quark and the lightest neutralino. Final states with $\geq 2$ jets, dileptons, and missing energy are expected in a subsequent decay of the second or third lightest neutralinos into the lightest neutralino via an intermediate slepton ("light sleptons" case) or $Z$ boson ("heavy sleptons" case). The opposite-sign same flavor dilepton mass distribution after subtracting the opposite-sign different flavor distribution shows a clear edge in the case of light sleptons. The significance for discovering such a scenario is calculated with optimized cuts in both light and heavy sleptons cases.

Nazionalizzare Kazan’: Architettura e nazionalismo tataro nella capitale del Tatarstan (1991-2010)

description: Alla fine degli anni Ottanta in Tatarstan si diffuse e divenne egemonico un discorso politico nazionalista incentrato sulla necessità della riaffermazione culturale della ‘nazione tatara’ e sulla rivendicazione di una maggiore autonomia e sovranità. L’articolo mostra come la leadership repubblicana abbia cercato con successo di appropriarsene selettivamente, onde da un lato dare legittimità alla richiesta di una maggiore autonomia da Mosca, alle nuove istituzioni e al proprio sistema di potere, dall’altro estromettere i nazionalisti più radicali. L’articolo si focalizza in particolare sul ruolo cruciale svolto in questi sviluppi dal rimodellamento del paesaggio urbano e architettonico di Kazan’, e su come la sua conseguente, parziale ‘tatarizzazione’ sia stata il risultato di un compromesso tra le istanze nazionaliste tatare e la necessità di evitare lo scontro con Mosca e con la popolazione ‘etnicamente russa’ della repubblica. In the end of the 1980s Tatarstan saw the spreading and later the hegemony of a nationalist political discourse centred on the need for a cultural reassertion of the ‘Tatar nation’ and on the claim for more autonomy and sovereignty. The article shows how the republican leadership was successfully in selectively appropriating this discourse in order to give legitimacy to its claim for more autonomy from Moscow and to its new institutions and power system, but also to neutralize radical nationalists. The article focuses in particular on the crucial role played in this context by the reshaping of Kazan’s urban and architectural landscape and on how its subsequent, partial ‘Tatarization’ was the result of a compromise between Tatar nationalist claims and the necessity to avoid a direct confrontation with Moscow and with the republic’s ‘ethnic Russians’.

description: Le politiche di riduzione della spesa pubblica condotte a partire dalla crisi finanziaria del 2008 hanno funto da fattori scatenanti di tutta una serie di riforme territoriali in Europa. Se il potere regionale è più marcato in Italia che in Francia, la questione della struttura territoriale reticolare si è posta in termini simili. Questo articolo ritorna sugli argomenti della controversia sulla soppressione del livello intermedio (province e dipartimenti) e sulla natura dei blocchi politici che contribuiscono alla sua conservazione (perlomeno come circoscrizione statale). The policies of reduction of public spending carried out since the 2008 financial crisis have triggered a whole series of territorial reforms in Europe. If regional power is more marked in Italy than in France, the question of its web-like territorial structure has been posed in similar terms. This article analyzes the arguments of the controversy on the suppression of the intermediate level (provinces and departments) and on the nature of the political blocs that contribute to its maintenance (at least as state constituency).

Partiti e autodeterminazione in Südtirol/Alto Adige: competizione etnica e strategie dei partiti tra autonomia e secessione

description: Dalla chiusura della vertenza sulla «questione sudtirolese» nel 1992, la politica etnica in Alto Adige/Südtirol ha subìto profondi cambiamenti. Il sistema consociativo, implementato per attenuare tendenze centrifughe, da allora ha iniziato a perdere il proprio equilibrio a causa delle pressioni secessioniste provenienti dall’arena intra-etnica tedesca. Adottando una prospettiva strategica verso l’autodeterminazione, il presente contributo analizza l’evoluzione delle strategie dei partiti etnoregionalisti sudtirolesi sulla dimensione territoriale ed europea della competizione elettorale. In linea con le nuove ricerche sulle strategie dei partiti viene dimostrato che i partiti etnici non solo possiedono le capacità strategiche di assumere posizioni riguardo a diverse dimensioni della competizione, ma anche di riformularle in chiave nuova. Mentre la saliente competizione etnica in Sudtirolo ha portato ad un nuovo frame territoriale, il consenso proeuropeo ha assunto le sembianze di un conflitto posizionale. Since the settlement of the controversy on the «South Tyrol question» in 1992, ethnic politics in Alto Adige/Südtirol has deeply changed. Since then, the compromise system implemented to soften the centrifugal tendencies has begun to lose its balance, due to the pressures for secession coming from the German intra-ethnic arena. Adopting a strategic perspective towards self-determination, the present study analyzes the evolution of the strategies of South Tyrol ethno-regionalist parties with regard to the territorial and European dimension of the electoral competition. In line with the new researches on party strategies, it is shown that ethnic parties not only do possess the strategic ability to take up a position on various aspects of the competition, but they are also able to reformulate them in new terms. While the salient ethnic competition in South Tyrol has led to a new territorial frame, the pro-EU consensus has taken the form of a positional conflict.

description: Le origini dell’estinto Partido Andalucista (PA) risalgono al 1965. Negli anni Settanta gli andalusisti promossero l’autogoverno per l’Andalusia ed elaborarono una proposta basata sulle idee di Blas Infante, la teoria della dipendenza, il socialismo autogestionario e il personalismo cristiano. Dopo la costituzione del PSA si estesero in Catalogna in un contesto politico molto complesso. Con l’obiettivo di rappresentare gli interessi degli immigrati andalusi, si presentarono con successo nelle elezioni catalane del 1980. The origins of the no longer existing Partido Andalucista (PA) date back to 1965. In the 1970s Andalusiansts promoted self-government for Andalusia and elaborated a proposal based on Blas Infante’s ideas, on the theory of dependency, autogestionario Socialism, and Christian personalism. After the establishment of the PSA they spread to Catalonia, in a very complex political context. In order to represent the interests of Andalusian immigrants, they successfully took part in the 1980 Catalan elections.

Diagnosing the time-dependence of active region core heating from the emission measure: I. Low-frequency nanoflares

description: Observational measurements of active region emission measures contain clues to the time-dependence of the underlying heating mechanism. A strongly non-linear scaling of the emission measure with temperature indicates a large amount of hot plasma relative to warm plasma. A weakly non-linear (or linear) scaling of the emission measure indicates a relatively large amount of warm plasma, suggesting that the hot active region plasma is allowed to cool and so the heating is impulsive with a long repeat time. This case is called {\it low-frequency} nanoflare heating and we investigate its feasibility as an active region heating scenario here. We explore a parameter space of heating and coronal loop properties with a hydrodynamic model. For each model run, we calculate the slope $α$ of the emission measure distribution $EM(T) \propto T^α$. Our conclusions are: (1) low-frequency nanoflare heating is consistent with about 36% of observed active region cores when uncertainties in the atomic data are not accounted for; (2) proper consideration of uncertainties yields a range in which as many as 77% of observed active regions are consistent with low-frequency nanoflare heating and as few as zero; (3) low-frequency nanoflare heating cannot explain observed slopes greater than 3; (4) the upper limit to the volumetric energy release is in the region of 50 erg cm$^{-3}$ to avoid unphysical magnetic field strengths; (5) the heating timescale may be short for loops of total length less than 40 Mm to be consistent with the observed range of slopes; (6) predicted slopes are consistently steeper for longer loops.

description: Partendo da Taiwan, l’articolo sviluppa una serie di riflessioni sulla storia dei nazionalismi di tipo creolo, ufficiale, linguistico e a lunga distanza in Asia e in Europa, e sulle loro implicazioni per la Cina. Dopo una indagine comparata di vari esempi e modelli di queste varietà di nazionalismi, viene sostenuto che una netta e inequivocabile distinzione tra nazionalismo asiatico ed europeo è priva di qualsivoglia validità scientifica. The article develops a series of reflections from Taiwan on the history of creole and official, linguistic and long-distance nationalisms in Asia and Europe, and their implications for China. After a comparative survey of various instances and patterns of such varieties of nationalism, it argues that any sharp and unequivocal distinction between Asian and European nationalism lacks all scientific validity.

description: The primary challenge for experiments measuring the neutral hydrogen power spectrum from the Epoch of Reionization (EoR) are mode-mixing effects where foregrounds from very bright astrophysical sources interact with the instrument to contaminate the EoR signal. In this paper we identify a new type of mode-mixing that occurs when measurements from non-identical baselines are combined for increased power spectrum sensitivity. This multi-baseline effect dominates the mode-mixing power in our simulations and can contaminate the EoR window, an area in Fourier space previously identified to be relatively free of foreground power.

description: We report on terahertz frequency-domain spectroscopy (THz-FDS) experiments in which we measure charge carrier dynamics and excitations of thin-film superconducting systems at low temperatures in the THz spectral range. The characteristics of the set-up and the experimental procedures are described comprehensively. We discuss the single-particle density of states and a theory of electrodynamic absorption and optical conductivity of conventional superconductors. We present the experimental performance of the setup at low temperatures for a broad spectral range from 0.1 - 1.1 THz by the example of ultra-thin films of weakly disordered superconductors niobium nitride (NbN) and tantalum nitride (TaN) with different values of critical temperatures. Furthermore, we analyze and interpret our experimental data within the framework of conventional Bardeen-Cooper-Schrieffer (BCS) theory of superconductivity.

description: Bosonic Integer Quantum Hall (IQH) phases are a class of symmetry protected topological (SPT) phases that, similar to the fermionic IQH states, support a quantized Hall conductance. They, however, require interactions for their realization. Here we study quantum Hall plateau transitions between a trivial insulator and a bosonic IQH phase, in a clean system. Generically, we find an intervening superfluid phase. The presence of additional symmetries, however, can potentially lead to a direct transition between these phases. We employ a fermionic parton description that captures both the insulating phases as well as the transition between them. The critical theory is massless QED-3 with Nf = 2 fermion flavors. The fermions have a surprisingly simple interpretation - they are vortices of the superfluid. Therefore the universal conductivity at the transition, assuming it is continuous, equals the universal resistivity of Dirac fermions in QED-3. We also briefly comment on sigma model descriptions of the transition and the surface states of related 3D SPT phases.

Dal tabù alla sua incompleta istituzionalizzazione: il caso del potere regionale francese From taboo to its incomplete institutionalization: the case of french regional power

description: Questo articolo si propone di analizzare la dinamica della regionalizzazione francese per mezzo di una duplice prospettiva comparata. Da un lato, la comparazione diacronica permette di cogliere il susseguirsi di tre grandi tappe storiche: inizialmente un lungo periodo di storico rifiuto di un potere regionale, poi l’emergere di una regionalizzazione funzionale che faceva della regione uno spazio di programmazione e coordinamento, e infine l’istituzionalizzazione, tardiva e incompiuta, di una collettività regionale. Dall’altro lato, il ricorso a una comparazione sincronica permette di valutare meglio la natura e i limiti della regionalizzazione francese di fronte alle dinamiche di regionalizzazione indotte dall’integrazione europea e soprattutto quelle osservate nell’ambito degli Stati unitari e regionalizzati. This article intends to analyze the dynamics of regionalization in France by means of a double comparative perspective. On the one hand, a diachronic comparison allows us to identify three important historical stages: first a long period characterized by a traditional refusal of any regional power, then the emergence of a functional regionalization that posited the region as a site of planning and coordination, and finally a late and incomplete institutionalization of regions as a collective subject. On the other hand, a synchronic comparison allows us to better evaluate the nature and the limits of French regionalization compared to the dynamics of regionalization brought about by European integration, most of all those observed in unitary and regionalized states.

description: We present a comprehensive study of the phonon dispersion in an underdoped, superconducting Ca$_{2-x}$CuO$_2$Cl$_2$ crystal. We interpret the results using lattice dynamical calculations based on a shell model, and we compare the results, to other hole-doped cuprates, in particular to the ones isomorphic to La$_{2-x}$Sr$_x$CuO$_4$ (LSCO). We found that an anomalous dip in the Cu-O bond stretching dispersion develops in oxychlorides with a simultaneous marked broadening of the mode. The broadening is maximum at $\approx (π/ (2a) ~ 0 ~ 0)$ that corresponds to the charge-modulations propagation vector. Our analysis also suggests that screening effects in calculations may cause an apparent cosine-shaped bending of the Cu-O bond-stretching dispersion along both the ($q$ 0 0) and ($q$ $q$ 0) directions, that is not observed on the data close to optimal doping. This observation suggests that the discrepancy between experimental data and \textit{ab-initio} calculations on this mode originates from an overestimation of the doping effects on the mode.
Un federalismo plurinazionale a due velocità: i segmenti sociali in Belgio e la loro partecipazione al processo di revisione costituzionale A case of two-speed multinational federalism: Belgium’s social segments and their participation in the constitutional amendment process

description: Il Belgio è una federazione che presenta diverse caratteristiche tipiche del federalismo plurinazionale. Nello Stato belga infatti convivono quattro segmenti sociali politicamente identificabili, sociologicamente distinti e giuridicamente riconosciuti, ossia i fiamminghi, i valloni, i brussellesi e i germanofoni. Eppure il federalismo plurinazionale belga molto spesso procede a due velocità, creando così una sorta di gerarchia fra i fiamminghi e i valloni da una parte e gli abitanti di Bruxelles e i germanofoni dall’altra. Oggetto del presente articolo è una discussione di questo fenomeno per quanto riguarda il processo di revisione costituzionale del Belgio. Un altro obiettivo dell’articolo è quello di formulare due modeste proposte di riforma per mitigare questa situazione. Belgium is a federation with many characteristics of multinational federalism. Indeed, in the Belgian context, there are four politically identifiable, sociologically distinct and legally recognized societal segments: Flemings, Walloons, Brussels’ inhabitants and German-speakers. Nevertheless, Belgian multinational federalism often follows a two-speed path, thus creating a form of hierarchy between, on the one hand, Flemings and Walloons, and, on the other hand, Brussels’ inhabitants and German-speakers. It is the object of this article to discuss this phenomenon, precisely with regard to Belgium’s constitutional amendment process. It is also its aim to articulate two modest proposals of reform to alleviate this situation.

Extreme Sensitivity of Output Directionality to Boundary Perturbation in Wavelength-Scale Microcavities

description: We report a surprising observation that the output directionality from wavelength-scale optical microcavities displays extreme sensitivity to deformations of the cavity shape. A variation of the cavity boundary on the order of ten thousandth of a wavelength may flip the output directions by 180 degrees. Our analysis based on a perturbation theory reveals that a tiny shape variation can cause a strong mixing of nearly degenerate cavity resonances with different angular momenta, and their interference determines the farfield emission pattern. This work shows the possibility of utilizing carefully-designed wavelength-scale microcavities for high-resolution detection and sensing applications.

description: We predict the existence and observational signatures of a new class of objects that assembled early, during the first billion years of cosmic time: Obese Black-hole Galaxies (OBGs). OBGs are objects in which the mass of the central black hole initially exceeds that of the stellar component of the host galaxy, and the luminosity from black-hole accretion dominates the starlight. From a cosmological simulation, we demonstrate that there are sites where star formation is initially inhibited and direct-collapse black holes (DCBHs) form due to the photo-dissociating effect of Lyman-Werner radiation on molecular hydrogen. We show that the formation of OBGs is inevitable, because the probability of finding the required extra-galactic environment and the right physical conditions in a halo conducive to DCBH formation is quite high in the early universe. We estimate an OBG number density of 0.009/Mpc^3 at z~8 and 0.03/Mpc^3 at z~6. Extrapolating from our simulation volume, we infer that the most luminous quasars detected at z~6 likely transited through an earlier OBG phase. We find that these primordial galaxies start off with an over-massive BH and acquire their stellar component from subsequent merging as well as in-situ star formation. In doing so, they inevitably go through an OBG phase dominated by the accretion luminosity at the Eddington rate or below, released from the growing BH. The OBG phase is characterised by an ultra-violet (UV) spectrum with slope of beta ~ -2.3 and the absence of a Balmer Break. OBGs should also be spatially unresolved, and are expected to be brighter than the majority of known high-redshift galaxies. OBGs could potentially be revealed via HST follow-up imaging of samples of brighter Lyman-break galaxies provided by wide-area ground-based surveys such as UltraVISTA, and should be easily uncovered and studied with instruments aboard JWST...(abridged)
