description: We present 12CO J = 2-1 line observations of G54.1+0.3, a composite supernova remnant with a mid-infrared (MIR) loop surrounding the central pulsar wind nebula (PWN). We mapped an area of 12' x 9' around the PWN and its associated MIR loop. We confirm two velocity components that had been proposed to be possibly interacting with the PWN/MIR-loop; the +53 km/s cloud that appears in contact with the eastern boundary of the PWN and the +23 km/s cloud that has CO emission coincident with the MIR loop. We have not found a direct evidence for the interaction in either of these clouds. Instead, we detected an 5'-long arc-like cloud at +15-+23 km/s with a systematic velocity gradient of ~3 km/s/arcmin and broad-line emitting CO gas having widths (FWHM) of <7 km/s in the western interior of the supernova remnant. We discuss their association with the supernova remnant.

description: The lack of evidence for new physics beyond the standard model at the LHC points to a paucity of new particles near the weak scale. This suggests that the weak scale is tuned and that supersymmetry, if present at all, is realized at higher energies. The measured Higgs mass constrains the scalar sparticles to be below 10^5 TeV, while gauge coupling unification favors Higgsinos below 100 TeV. Nevertheless, in many models gaugino masses are suppressed and remain within reach of the LHC. Tuning the weak scale and the renormalization group evolution of the scalar masses constrain Split model building. Due to the small gaugino masses, either the squarks or the up-higgs often run tachyonic; in the latter case, successful electroweak breaking requires heavy higgsinos near the scalar sparticles. We discuss the consequences of tuning the weak scale and the phenomenology of several models of Split supersymmetry including anomaly mediation, U(1)_(B-L) mediation, and Split gauge mediation.

description: Fitness landscape analysis aims to understand the geometry of a given optimization problem in order to design more efficient search algorithms. However, there is a very little knowledge on the landscape of multiobjective problems. In this work, following a recent proposal by Zitzler et al. (2010), we consider multiobjective optimization as a set problem. Then, we give a general definition of set-based multiobjective fitness landscapes. An experimental set-based fitness landscape analysis is conducted on the multiobjective NK-landscapes with objective correlation. The aim is to adapt and to enhance the comprehensive design of set-based multiobjective search approaches, motivated by an a priori analysis of the corresponding set problem properties.

description: We present high angular resolution Submillimeter Array (SMA) and Karl G. Jansky Very Large Array (VLA) observations of the massive protocluster G18.67+0.03. Previously targeted in maser surveys of GLIMPSE Extended Green Objects (EGOs), this cluster contains three Class I methanol maser sources, providing a unique opportunity to test the proposed role of Class I masers as evolutionary indicators for massive star formation. The millimeter observations reveal bipolar molecular outflows, traced by 13CO(2-1) emission, associated with all three Class I maser sources. Two of these sources (including the EGO) are also associated with 6.7 GHz Class II methanol masers; the Class II masers are coincident with millimeter continuum cores that exhibit hot core line emission and drive active outflows, as indicated by the detection of SiO(5-4). In these cases, the Class I masers are coincident with outflow lobes, and appear as clear cases of excitation by active outflows. In contrast, the third Class I source is associated with an ultracompact HII region, and not with Class II masers. The lack of SiO emission suggests the 13CO outflow is a relic, consistent with its longer dynamical timescale. Our data show that massive young stellar objects associated only with Class I masers are not necessarily young, and provide the first unambiguous evidence that Class I masers may be excited by both young (hot core) and older (UC HII) MYSOs within the same protocluster.

title: A vocabulary of the Antique. An archaeological reconstruction and the reception of the Volta Dorata of the Domus Aurea of Nero
Creators: name: Brunetti, Marco

Year: 2020

description: The aim of my research is to provide a critical analysis and comparison of the graphic documents (prints, watercolors, drawings) that depict and show the decoration of the Volta Dorata in the Domus Aurea of Nero. Precisely, my research is addressed towards two aspects that are strictly related to each other: the first is to reconstruct the original appearance of the Volta Dorata through the comparison of the graphic documentation; the second is to assess how such documentation can help us in understanding how and why artists from the Renaissance age copied this vault. Thanks to the evidence that comes from the graphic documents, in the First Chapter, it has been possible to define how, since the discovery of the underground grottoes in the 70s of the 15th century, antiquarians and artists were able to hypothesize that those paintings might have belonged to the Domus Aurea of Nero. However, since the 17th century, such insight has been replaced by other interpretations, e.g. Titus’ and Trajan’s Baths. Only in the 19th century, because of the study of De Romanis (1822), Piale and, afterward, Lanciani were able to recover the first identification. The Second Chapter consists of the catalogue of the graphic witnesses and the documents are analyzed, focusing the attention on the archaeological aspects and artistic features (i.e. stylistic, material, techniques, and attribution issues). Thanks to the evidence from the catalogue, in the Third Chapter, after a preliminary discussion of room 80 in the Domus Aurea, it has been possible to show which were the colors and the type of decorations of the Volta Dorata but, mostly, to compare the different figural scenes. Thanks to such analysis, a potential iconological message of the decorative system has been detected and put in relation with the literary themes that can be seen in some figural scenes of the Domus Aurea’s ceilings. In the Fourth Chapter, the data that come from the catalog are discussed in order to assess the working methodology of artists from the 16th to 19th century. Precisely, it has been investigated how their interest and practice of copying caused a modification of the scene depicted. Then, considering the 16th century, through some cases of the modern ceilings of Peruzzi, Pinturicchio and Raphael’s workshop, it has been possible to detect the reception and the assimilation of the artistic language that Renaissance artists found in the Volta Dorata.

description: In this paper, we conduct a fitness landscape analysis for multiobjective combinatorial optimization, based on the local optima of multiobjective NK-landscapes with objective correlation. In single-objective optimization, it has become clear that local optima have a strong impact on the performance of metaheuristics. Here, we propose an extension to the multiobjective case, based on the Pareto dominance. We study the co-influence of the problem dimension, the degree of non-linearity, the number of objectives and the correlation degree between objective functions on the number of Pareto local optima.

description: Negli anni Cinquanta Mario Soldati compone un affresco del paesaggio italiano che si snoda tra cinema e televisione. Il primo risultato è un’inchiesta-documentario Viaggio nella Valle del Po alla ricerca dei cibi genuini (1957), con musiche di Nino Rota; il secondo invece Chi legge? Viaggio lungo il Tirreno (1960) con Cesare Zavattini. A soli tre anni di distanza, la rappresentazione dell’identità popolare nei due reportage cambia in modo netto. Nel primo dei due viaggi, Soldati non incontra ancora italiani ma piemontesi, lombardi, veneti, emiliani e si sofferma soprattutto sulle specificità e sulle differenze. Nella seconda prova il paesaggio è animato da persone (gli italiani) e si avverte fortemente l’influenza zavattiniana.

description: We introduce a new method to calculate the multi-scale 3D filamentation of SDSS DR5 galaxy clusters and also applied it to N-body simulations. We compared the filamentation of the observed vs. mock samples in metric space on scales from 8 Mpc to 30 Mpc. Mock samples are closer to the observed sample than random samples, and one of the mock samples behaves better than another one. We also find that the observed sample has a large filamentation value at a scale of 10 Mpc, which is not found from either mock samples or random samples. Key words: filamentation, metric space, galaxy clusters, SDSS DR5.
Dark matter, dark energy, and dark radiation coupled with a transversal interaction

description: We investigate a cosmological scenario with three interacting components that includes dark matter, dark energy, and radiation in the spatially flat Friedmann-Robertson-Walker universe. We introduce a 3-dimensional internal space, the interaction vector $\mathbf{Q}=(Q_{x}, Q_{m}, Q_{r})$ satisfying the constraint plane $Q_{x}+ Q_{m}+ Q_{r}=0$, the barotropic index vector $ \boldmath $γ$=(\ga_x,\ga_m,\ga_r)$ and select a transversal interaction vector $\mathbf{Q_t}$ in a sense that $\mathbf{Q_t}\cdot \boldmath $γ$=0$. We exactly solve the source equation for a linear $\mathbf{Q_t}$, that depends on the total energy density and its derivatives up to third order, and find all the component energy densities. We obtain a large set of interactions for which the source equation admits a power law solution and show its asymptotic stability by constructing the Lyapunov function. We apply the $χ^{2}$ method to the observational Hubble data for constraining the cosmic parameters, and analyze the amount of dark energy in the radiation era for the above linear $\mathbf{Q_t}$. It turns to be that our model fulfills the severe bound of $Ω_{x}(z\simeq 1100)<0.1$ and is consistent with the future constraints achievable by Planck and CMBPol experiments.

Role of bond orientational order in the crystallization of hard spheres

Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: With computer simulations of the hard sphere model, we examine in detail the microscopic pathway connecting the metastable melt to the emergence of crystalline clusters. In particular we will show that the nucleation of the solid phase does not follow a two-step mechanism, where crystals form inside dense precursor regions. On the contrary, we will show that nucleation is driven by fluctuations of orientational order, and not by the density fluctuations. By considering the development of the pair-excess entropy inside crystalline nuclei, we confirm that orientational order precedes positional order. These results are at odd with the idea of a two-step nucleation mechanism for fluids without a metastable liquid-liquid phase separation. Our study suggests the pivotal role of bond orientational ordering in triggering crystal nucleation.

description: The transport of suspended Brownian particles dc-driven along corrugated narrow channels is numerically investigated in the regime of finite damping. We show that inertial corrections cannot be neglected as long as the width of the channel bottlenecks is smaller than an appropriate particle diffusion length, which depends on the the channel corrugation and the drive intensity. Being such a diffusion length inversely proportional to the damping constant, transport through sufficiently narrow obstructions turns out to be always sensitive to the viscosity of the suspension fluid. The inertia corrections to the transport quantifiers, mobility and diffusivity, markedly differ for smoothly and sharply corrugated channels.

In this paper we present a counterpart of this formula, corresponding to the {\it exterior} of a concave hexagon obtained by turning 120 degrees after drawing each side (MacMahon's hexagon is obtained by turning 60 degrees after each step).

description: This paper considers linear regression models when neither the response variable nor the covariates can be directly observed, but are measured with multiplicative distortion measurement errors. The distortion functions for this kind of measurement errors are modelled under a general identifiability condition. For parameter estimation, we propose two calibration procedures: the conditional mean calibration based least squares estimation and the varying coefficient based estimation. The asymptotic normal confidence intervals and empirical likelihood confidence intervals are also proposed. Simulation studies are conducted to compare the proposed calibration procedures and a real example is analysed to illustrate its practical usage.

description: We provide a formalism to describe deterministic emission of single photons with tailored spatial and temporal profiles from a regular array of multi-level atoms. We assume that a single collective excitation is initially shared by all the atoms in a metastable atomic state, and that this state is coupled by a classical laser field to an optically excited state which rapidly decays to the ground atomic state. Our model accounts for the different field polarization components via re-absorption and emission of light by the Zeeman manifold of optically excited states.
Patchy Screening of the Cosmic Microwave Background by Inhomogeneous Reionization

description: We derive a constraint on patchy screening of the cosmic microwave background from inhomogeneous reionization, using off-diagonal TB and TT correlations in WMAP-7 temperature/polarization data. We interpret this as a constraint on the rms optical-depth fluctuation Δτ as a function of a coherence multipole Lc. We relate these parameters to a comoving coherence scale, of bubble size Rc, in a phenomenological model where reionization is instantaneous but occurs on a crinkly surface, and also to the bubble size in a model of "Swiss cheese" reionization where bubbles of fixed size are spread over some range of redshifts. The current WMAP data are still too weak, by several orders of magnitude, to constrain reasonable models, but forthcoming Planck and future EPIC data should begin to approach interesting regimes of parameter space. We also present constraints on the parameter space imposed by the recent results from the EDGES experiment.

description: We consider the decay modes of the heavy $q^\prime\bar{q^\prime}$ bound states originating from Higgs boson exchange between quark -- anti-quark pair. In case of a small coupling between the fourth and lower generation the main decay mode is $q^\prime\bar{q^\prime}$ annihilation. We show that for a vector state the dominant decay modes are Higgs-gamma and Higgs-Z decays, while for a pseudoscalar state the strong two-gluon decay mode dominates. The bound states are very narrow. The ratio of the total width to the binding energy is less than 1% if we are not extremely close to the critical quark mass where the binding energy is very small. The discussed decay modes exist for any fermion-antifermion bound states including heavy leptons and heavy neutrinos if their masses are high enough to form a bound state due to attractive Higgs boson exchange potential.

description: The time-wise and space-wise approaches are generally applied to data processing and error analysis for satellite gravimetry missions. But both the approaches, which are based on least-squares collocation, address the whole effect of measurement errors and estimate the resolution of gravity field models mainly from a numerical point of indirect view. Moreover, requirement for higher accuracy and resolution gravity field models could make the computation more difficult, and serious numerical instabilities arise. In order to overcome the problems, this study focuses on constructing a direct relationship between power spectral density of the satellite gravimetry measurements and coefficients of the Earth's gravity potential. Based on two-dimensional Fourier transform, the relationship is analytically concluded. By taking advantage of the analytical expression, it is efficient and distinct for parameter estimation and error analysis of missions. From the relationship and the simulations, it is analytically confirmed that the low-frequency noise affects the gravity field recovery in all degrees for the instance of satellite gradiometer recovery mission. Furthermore, some other results and suggestions are also described.

description: Starting from the two-point covariance function derived in [1], we have developed a toy model to investigate the effect of gluonic fluctuations on the transverse energy profile predicted by MC-KLN Color-Glass Condensate initial conditions. We find that the effect of these fluctuations on the eccentricity harmonics varies strongly with the correlation length and consequently the value of the fixed saturation momentum Qs used in [1]. Using approximate values for the minimum and maximum saturation momenta probed at RHIC in Au-Au collisions, we estimate the increase in the eccentricity coefficients resulting from gluonic fluctuations is as large as 10 to 20 percent in central collisions.

description: This paper extends a recently proposed model for combinatorial landscapes: Local Optima Networks (LON), to incorporate a first-improvement (greedy-ascent) hill-climbing algorithm, instead of a best-improvement (steepest-ascent) one, for the definition and extraction of the basins of attraction of the landscape optima. A statistical analysis comparing best and first improvement network models for a set of NK landscapes, is presented and discussed. Our results suggest structural differences between the two models with respect to both the network connectivity, and the nature of the basins of attraction. The impact of these differences in the behavior of search heuristics based on first and best improvement local search is thoroughly discussed.

description: We study the algebraic structure of the Dirac fermion state in the organic conductor, α-(BDET-TTF)_2I_3. We find a pair of generators for the Hamiltonian of α-(BDET-TTF)_2I_3 that describes the chirality of Dirac fermions. The phase parameters associated with those generators have an intimate and simple relationship with the positions of the Dirac points in the Brillouin zone. By making use of the form of the generators, a reduced form of the Hamiltonian is constructed that shares some characteristic features of the Dirac fermions with α-(BDET-TTF)_2I_3. For the reduced Hamiltonian we present the analytic expression for the Dirac point position that sits at arbitrary point in the Brillouin zone determined by the hopping parameters.

description: We present recent developments on the role of the running coupling constant at the intersection of perturbative and nonperturbative QCD. A number of experiments show a smooth transition from small to large scales given by the four-momentum transfer in the reactions. This is at variance with perturbative QCD where the running coupling constant becomes infinite when the scale equals $Λ_{\tiny QCD}$. Approaches using an effective coupling constant could help interpret the opposite trend of data as compared to standard perturbative QCD predictions. We give an overview of the role of the coupling constant in the procedure to match nonperturbative hadronic model to perturbative QCD and we propose an extraction of an effective coupling constant from inclusive electron proton scattering data at large Bjorken x.

Θα πρέπει όμως να αναφερθεί ότι η πτωτική πορεία στα έσοδα των ελληνικών νοικοκυριών, δυστυχώς δεν επιτρέπει σε Έλληνες τουρίστες, όχι μόνο τον παρατεταμένο τουρισμό, τουλάχιστον όπως αυτός είχε λάβει τροπή τα έτη προ κρίσης, αλλά και γενικότερα τις διακοπές. Η σημασία του κλάδου των ταξιδιών και του τουρισμού για την οικονομία θα αναλυθεί διεξοδικά στην συγκεκριμένη μελέτη, ενώ θα παρουσιαστούν συγκεκριμένα στατιστικά στοιχεία για τα έτη που προηγήθηκαν σε διάφορα  μεγέθη  του  τουρισμού,  οπότε  και  θα  σημειωθούν  οι  δείκτες  μεταβολής  των συγκεκριμένων μεγεθών και θα πραγματοποιηθεί η σχετική κριτική. Η μελέτη επικεντρώνεται στις περιπτώσεις της Ελλάδας και της Αιγύπτου μέσα μια ιστορική ανασκόπηση αλλά και παρουσίαση της υφιστάμενης κατάστασης.

description: An avoidance problem of configurations in 4-cycle systems is investigated by generalizing the notion of sparseness, which is originally from Erdős' r-sparse conjecture on Steiner triple systems. A 4-cycle system of order v, 4CS(v), is said to be r-sparse if for every integer j satisfying 1 < j < r+1 it contains no configurations consisting of j 4-cycles whose union contains precisely j+3 vertices. If an r-sparse 4CS(v) is also free from copies of a configuration on two 4-cycles sharing a diagonal, called the double-diamond, we say it is strictly r-sparse. In this paper, we show that for every admissible order v there exists a strictly 4-sparse 4CS(v). We also prove that for any positive integer r > 1 and sufficiently large integer v there exists a constant number c such that there exists a strictly r-sparse 4-cycle packing of order v with cv^2 4-cycles.

description: L’operazione di pagamento nella direttiva PSD2 deve essere inquadrata come un procedimento per il trasferimento di fondi. La circostanza che il denaro sia misura e oggetto sia delle obbligazioni risarcitorie sia di quelle restitutorie può portare a confusioni. L’analisi dei ruoli dei prestatori di servizi di pagamento e degli utenti porta a criticare l’attuazione italiana dell’art. 73.2 della direttiva PSD2, per il rischio di overcompensation a carico dei nuovi operatori (TPP - Third Party Providers).

description: Una delle novità più rilevanti della nuova Direttiva sui servizi di pagamento è l’aver disciplinato una nuova categoria di prestatori di servizi, i Third Party Providers (TPP). Si tratta di soggetti che – differentemente da tutti gli altri già regolati dalla Direttiva – non gestiscono somme di denaro della clientela ma informazioni relative a conti di pagamento. Chi sono e cosa fanno i TPP? Quali regole sono previste per loro e quali i rapporti con le banche? Quali sfide per il prossimo futuro ne derivano, per i TPP stessi, le banche e le Autorità di vigilanza? Questo scritto risponde a queste domande.

In einem frechen Mix aus Tempo, Slapstick und Urbanität spiegelten die sogenannten Zeitopern das großstädtische Lebensgefühl wider und setzten die Errungenschaften des Großstadtlebens genussvoll in Szene. Exemplarisch stellte Ernst Kreneks weltweit erfolgreiche Zeitoper „Jonny spielt auf“ das Landleben mit Natur und moralischer Integrität der modernen Großstadt mit Maschinen, Technik und moralischem Verfall gegenüber.

description: In this article we study convex integer maximization problems with composite objective functions of the form $f(Wx)$, where $f$ is a convex function on $\R^d$ and $W$ is a $d\times n$ matrix with small or binary entries, over finite sets $S\subset \Z^n$ of integer points presented by an oracle or by linear inequalities. Continuing the line of research advanced by Uri Rothblum and his colleagues on edge-directions, we introduce here the notion of {\em edge complexity} of $S$, and use it to establish polynomial and constant upper bounds on the number of vertices of the projection $\conv(WS)$ and on the number of linear optimization counterparts needed to solve the above convex problem. Two typical consequences are the following. First, for any $d$, there is a constant $m(d)$ such that the maximum number of vertices of the projection of any matroid $S\subset\{0,1\}^n$ by any binary $d\times n$ matrix $W$ is $m(d)$ regardless of $n$ and $S$; and the convex matroid problem reduces to $m(d)$ greedily solvable linear counterparts. In particular, $m(2)=8$. Second, for any $d,l,m$, there is a constant $t(d;l,m)$ such that the maximum number of vertices of the projection of any three-index $l\times m\times n$ transportation polytope for any $n$ by any binary $d\times(l\times m\times n)$ matrix $W$ is $t(d;l,m)$; and the convex three-index transportation problem reduces to $t(d;l,m)$ linear counterparts solvable in polynomial time.
Breathing mode of two-dimensional atomic Fermi gases in harmonic traps

description: For two-dimensional (2D) atomic Fermi gases in harmonic traps, the SO(2,1) symmetry is broken by the interatomic interaction explicitly via the contact correlation operator. Consequently the frequency of the breathing mode $ω_B$ of the 2D Fermi gas can be different from $2ω_0$, with $ω_0$ the trapping frequency of harmonic potentials. At zero temperature, we use the sum rules of density correlation functions to yield upper bounds for $ω_B$. We further calculate $ω_B$ through the Euler equations in the hydrodynamic regime. The obtained value of $ω_B$ satisfies the upper bounds and shows deviation from $2ω_0$ which can be as large as about 8%.

description: We demonstrate experimentally a new form of induced transparency, i.e., chaos-induced transparency, in a slightly deformed microcavity which support both continuous chaotic modes and discrete regular modes with Q factors exceeding 3X?10^7. When excited by a focused laser beam, the induced transparency in the transmission spectrum originates from the destructive interference of two parallel optical pathways: (i) directly refractive excitation of the chaotic modes, and (ii) excitation of the ultra-high-Q regular mode via chaos-assisted dynamical tunneling mechanism coupling back to the chaotic modes. By controlling the focal position of the laser beam, the induced transparency experiences a highly tunable Fano-like asymmetric lineshape. The experimental results are modeled by a quantum scattering theory and show excellent agreement. This chaos-induced transparency is accompanied by extremely steep normal dispersion, and may open up new possibilities a dramatic slow light behavior and a significant enhancement of nonlinear interactions.

New results in RR Lyrae modeling: convective cycles, additional modes and more

description: Recent theoretical and observational findings breathed new life into the field of RR Lyrae stars. The ever more precise and complete measurements of the space asteroseismology missions revealed new details, such as the period doubling and the presence of the additional modes in the stars. Theoretical work also flourished: period doubling was explained and an additional mode has been detected in hydrodynamic models as well. Although the most intriguing mystery, the Blazhko-effect has remained unsolved, new findings indicate that the convective cycle model can be effectively ruled out for short- and medium-period modulations. On the other hand, the plausibility of the radial resonance model is increasing, as more and more resonances are detected both in models and stars.

description: We present positions, kinematics, and the planetary nebula luminosity function (PNLF) for 35 planetary nebulae (PNe) in the nearest starburst galaxy IC10 extending out to 3kpc from the galaxy's centre. We take advantage of the deep imaging and spectroscopic capabilities provided by the spectrograph FOCAS on the 8.2m Subaru telescope. The PN velocities were measured through the slitless-spectroscopy technique, which allows us to explore the kinematics of IC10 with high precision. Using these velocities, we conclude that there is a kinematic connection between the HI envelope located around IC10 and the galaxy's PN population. By assuming that the PNe in the central regions and in the outskirts have similar ages, our results put strong observational constraints on the past tidal interactions in the Local Group. This is so because by dating the PN central stars, we, therefore, infer the epoch of a major episode of star formation likely linked to the first encounter of the HI extended envelope with the galaxy. Our deep [OIII] images also allow us to use the PNLF to estimate a distance modulus of 24.1+/-0.25, which is in agreement with recent results in the literature based on other techniques.
