description: Here we investigate the dynamics of indirect reciprocity on networks, a type of social dynamics in which the attitude of individuals, either cooperative or antagonistic, toward other individuals changes over time by their actions and mutual monitoring. We observe an absorbing state phase transition as we change the network's link or edge density. When the edge density is either small or large enough, opinions quickly reach an absorbing state, from which opinions never change anymore once reached. In contrast, if the edge density is in the middle range the absorbing state is not reached and the state keeps changing thus being active. The result shows a novel effect of social networks on spontaneous group formation.

description: In this paper, we study a (p-adic) geometric analogue for abelian varieties over a function field of characteristic p of the cyclotomic Iwasawa theory and the non-commutative Iwasawa theory for abelian varieties over a number field initiated by Mazur and Coates respectively. We will prove some analogue of the principal results obtained in the case over a number field and we study new phenomena which did not happen in the case of number field case. We propose also a conjecture which might be considered as a counterpart of the principal conjecture in the case over a number field. \par This is a preprint which is distributed since 2005 which is still in the process of submision. Following a recent modification of some technical mistakes in the previous version of the paper as well as an amelioration of the presentation of the paper, we decide wider distribution via the archive.

description: Recently it has been suggested that fermions whose hopping amplitude is quenched to extremely low values provide a convenient source of local disorder for lattice bosonic systems realized in current experiment on ultracold atoms. Here we investigate the phase diagram of such systems, which provide the experimental realization of a Bose-Hubbard model whose local potentials are randomly extracted from a binary distribution. Adopting a site-dependent Gutzwiller description of the state of the system, we address one- and two-dimensional lattices and obtain results agreeing with previous findings, as far as the compressibility of the system is concerned. We discuss the expected peaks in the experimental excitation spectrum of the system, related to the incompressible phases, and the superfluid character of the {\it partially compressible phases} characterizing the phase diagram of systems with binary disorder. In our investigation we make use of several analytical results whose derivation is described in the appendices, and whose validity is not limited to the system under concern.

Tracing AGN accretion and star formation in Herschel galaxies
Creators: name: Delvecchio, Ivan <1987>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2014
Subjects: FIS/05 Astronomia e astrofisica

description: In this Thesis, we study the physical properties and the cosmic evolution of AGN and their host galaxies since z∼3. Our analysis exploits samples of star forming galaxies detected with Herschel at far-IR wavelengths (from 70 up to 500 micron) in different extragalactic surveys, such as COSMOS and the deep GOODS (South and North) fields. 

The broad-band ancillary data available in COSMOS and the GOODS fields, allows us to implement Herschel and Spitzer photometry with multi-wavelength ancillary data. We perform a multicomponent SED-fitting decomposition to decouple the emission due to star formation from that due to AGN accretion, and to estimate both host-galaxy parameters (such as stellar mass, M* and star formation rate, SFR), and nuclear intrinsic bolometric luminosities. We use the individual estimates of AGN bolometric luminosity obtained through SED-fitting decomposition to reconstruct the redshit evolution of the AGN bolometric luminosity function since z∼3. The resulting trends are used to estimate the overall AGN accretion rate density at different cosmic epochs and to trace the first ever estimate of the AGN accretion history from an IR survey. Later on, we focus our study on the connection between AGN accretion and integrated galaxy properties. We analyse the relationships of AGN accretion with galaxy properties in the SFR-M* plane and at different cosmic epochs. Finally, we infer what is the parameter that best correlates with AGN accretion, comparing our results with previous studies and discussing their physical implications in the context of current scenarios of AGN/galaxy evolution.
The Local Velocity Anomaly

description: There is a velocity discontinuity at about 7 Mpc between the galaxies of the Local Sheet that are moving together with low internal velocity dispersion and the adjacent structures. The Local Sheet bounds the Local Void. The Local Sheet is determined to have a peculiar velocity of 260 km/s away from the center of the void. In order for this large velocity to be generated by an absence of gravity, the Local Void must be at least 45 Mpc in diameter and be very empty.

description: We investigate the ac transport of magnetization in non-itinerant quantum systems such as spin chains described by the XXZ Hamiltonian. Using linear response theory, we calculate the ac magnetization current and the power absorption of such magnetic systems. Remarkably, the difference in the exchange interaction of the spin chain itself and the bulk magnets (i.e. the magnetization reservoirs), to which the spin chain is coupled, strongly influences the absorbed power of the system. This feature can be used in future spintronic devices to control power dissipation. Our analysis allows to make quantitative predictions about the power absorption and we show that magnetic systems are superior to their electronic counter parts.

description: We propose an efficient framework with compatibility between normal printing and printing with special color inks in this paper. Special color inks can be used for printing to represent some particular colors and specific optical properties, which are difficult to express using only CMYK inks. Special color layers are required in addition to the general color layer for printing with special color inks. We introduce a reversible data hiding (RDH) method to embed the special color layers into the general color layer without visible artifacts. The proposed method can realize both normal printing and printing with special color inks by using a single layer. Our experimental results show that the quality of the marked image is virtually identical to that of the original image, i.e., the general color layer.

Learning to discover: expressive Gaussian mixture models for multi-dimensional simulation and parameter inference in the physical sciences

description: We show that density models describing multiple observables with (i) hard boundaries and (ii) dependence on external parameters may be created using an auto-regressive Gaussian mixture model. The model is designed to capture how observable spectra are deformed by hypothesis variations, and is made more expressive by projecting data onto a configurable latent space. It may be used as a statistical model for scientific discovery in interpreting experimental observations, for example when constraining the parameters of a physical model or tuning simulation parameters according to calibration data. The model may also be sampled for use within a Monte Carlo simulation chain, or used to estimate likelihood ratios for event classification. The method is demonstrated on simulated high-energy particle physics data considering the anomalous electroweak production of a $Z$ boson in association with a dijet system at the Large Hadron Collider, and the accuracy of inference is tested using a realistic toy example. The developed methods are domain agnostic; they may be used within any field to perform simulation or inference where a dataset consisting of many real-valued observables has conditional dependence on external parameters.

description: In La morte di Socrate, Guardini cerca di comprendere e presentare il pensiero del Socrate platonico, leggendo attentamente i quattro dialoghi Eutifrone, Apologia, Critone e Fedone, e giustifica il titolo del presente saggio quale interpretazione del suo lavoro ermeneutico su Platone come espressione della sua stessa filosofia: «Lo scopo a cui mira questo lavoro è un'interpretazione filosofica intesa a scoprire che cosa pensi Platone; non già per fissare e derivare storicamente i suoi pensieri, ma per arrivare, sotto la loro guida, più vicino alla verità». In questo spirito, frutto di uno sforzo di interpretazione di Platone, ma allo stesso tempo di “filosofare con Eutifrone, Apologia, Critone e Fedone”, il lavoro di Guardini si compone di quattro grandi sezioni dedicate a un'analisi attenta e diretta alla verità di ciascuno di questi quattro dialoghi platonici. Il presente lavoro si concentrerà solo sul filosofare di Guardini con l'Eutifrone di Platone, un dialogo che affronta questioni decisive di filosofia della religione e di etica.

Bankruptcy : a proportional hazard approach
Creators: name: Betton, Sandra Ann
Publisher: name: University of British Columbia
Year: 2010

description: The recent dramatic increase in the corporate bankruptcy rate, coupled with a similar rate of increase in the bank failure rate, has re-awakened investor, lender and government interest in the area of bankruptcy prediction. Bankruptcy prediction models are of particular value to a firm's current and future creditors who often do not have the benefit of an actively traded market in the firm's securities from which to make inferences about the debtor's viability. The models commonly used by many experts in an endeavour to predict the possibility of disaster are outlined in this paper. The proportional hazard model, pioneered by Cox [1972], assumes that the hazard function, the risk of failure, given failure has not already occurred, is a function of various explanatory variables and estimated coefficients multiplied by an arbitrary and unknown function of time. The Cox Proportional Hazard model is usually applied in medical studies; but, has recently been applied to the bank failure question [Lane, Looney & Wansley, 1986]. The model performed well in the narrowly defined, highly regulated, banking industry. The principal advantage of this approach is that the model incorporates both the survival times observed and any censoring of data thereby using more of the available information in the analysis. Unlike many bankruptcy prediction models, such as logit and probit based regression models, the Cox model estimates the probability distribution of survival times. The proportional hazard model would, therefore, appear to offer a useful addition to the more traditional bankruptcy prediction models mentioned above. This paper evaluates the applicability of the Cox proportional hazard model in the more diverse industrial environment. In order to test this model, a sample of 109 firms was selected from the Compustat Industrial and Research Industrial data tapes. Forty one of these firms filed petitions under the various bankruptcy acts applicable between 1972 and 1985 and were matched to 67 firms which had not filed petitions for bankruptcy during the same period. In view of the dramatic changes in the bankruptcy regulatory environment caused by the Bankruptcy reform act of 1978, the legal framework of the bankruptcy process was also examined. The performance of the estimated Cox model was then evaluated by comparing its classification and descriptive capabilities to those of an estimated discriminant analysis based model. The results of this study indicate that while the classification capability of the Cox model was less than that of discriminant analysis, the model provides additional information beyond that available from the discriminant analysis.

description: We investigate the possibility that a (light) hidden sector extra photon receives its mass via spontaneous symmetry breaking of a hidden sector Higgs boson, the so-called hidden-Higgs. The hidden-photon can mix with the ordinary photon via a gauge kinetic mixing term. The hidden-Higgs can couple to the Standard Model Higgs via a renormalizable quartic term - sometimes called the Higgs Portal. We discuss the implications of this light hidden-Higgs in the context of laser polarization and light-shining-through-the-wall experiments as well as cosmological, astrophysical, and non-Newtonian force measurements. For hidden-photons receiving their mass from a hidden-Higgs we find in the small mass regime significantly stronger bounds than the bounds on massive hidden sector photons alone.

description: A singularly perturbed system for doubly diffusive convection equations, called the artificial compressible system, is considered on a two-dimensional infinite layer for a parameters range where the Hopf bifurcation occurs in the corresponding incompressible system. The spectrum of the linearized operator in a time periodic function space is investigated in detail near the bifurcation point when the singular perturbation parameter is small. The results of this paper are the basis of the study of the nonlinear Hopf bifurcation problem and the singular limit of the time periodic bifurcating solutions.

description: In this paper we discuss local averages of the energy density for the non-minimally coupled scalar quantum field, extending a previous investigation of the classical field. By an explicit example, we show that such averages are unbounded from below on the class of Hadamard states. This contrasts with the minimally coupled field, which obeys a state-independent lower bound known as a Quantum Energy Inequality (QEI). Nonetheless, we derive a generalised QEI for the non-minimally coupled scalar field, in which the lower bound is permitted to be state-dependent. This result applies to general globally hyperbolic curved spacetimes for coupling constants in the range $0

Productivity performance of U.S. trucking in the era of deregulation
Creators: name: Caskey, Kevin
Publisher: name: University of British Columbia
Year: 2010

description: This paper analyzes the impact on the productivity of the U. S. interstate trucking industry of changes in the regulatory climate in 1980. Two methods of analysis are used; Total Factor Productivity (TFP) and Neo-Classical Cost Function analysis. The industry's performance in 1978 is compared to the performance in 1982. Results of the Total Factor Productivity analysis indicate the TFP of the industry in 1982, after deregulation, was lower than that of 1978. However drawing conclusions from this result would be unfounded. TFP analysis assumes constant returns to scale. Cost Function analyses find that the U. S. trucking industry exhibits significant economies of scale. As the trucking industry does not have constant returns to scale, TFP cannot be used to draw conclusions about its economic performance. The results of the Cost Function analyses are dependent on which model is chosen. The variable measuring the effect of deregulation is either positive or negative depending on exactly what other variables are included in the model. In none of the initial models is this variable found to be significantly different from zero. After deleting six data points which produce extreme residuals and correspond to questionable observations, this variable is found to be positive and significant, indicating increased costs in 1982.

description: A singular perturbation problem from the artificial compressible system to the incompressible system is considered for a doubly diffusive convection when a Hopf bifurcation from the motionless state occurs in the incompressible system. It is proved that the Hopf bifurcation also occurs in the artificial compressible system for small singular perturbation parameter, called the artificial Mach number. The time periodic solution branch of the artificial compressible system is shown to converge to the corresponding bifurcating branch of the incompressible system in the singular limit of vanishing artificial Mach number.

description: This paper addresses two vital concerns in the debate on adaptation to climate change. First, how can countries prepare to manage the impact of climate-change induced natural disasters? Second, how can countries ensure that they have the governmental institutions required to manage the phenomenal challenge of adaptation to climate change? A range of economic and institutional measures are tested for their potential effects on natural disaster resilience and the quality of environmental governance. The findings suggest an important role is played by social and political institutions in determining the ability of countries to adapt to climate change and respond to natural disasters, in particular in the degree to which countries have succeeded in gender empowerment and the development of a robust civil society and nonprofit sector. As the climate change challenge moves from that of "proving the facts" to that of "implementing change," the authors suggest that international policymakers, donors, and activists must increasingly focus on building domestic policy environments that are conducive to the delivery of more effective environmental legislation, for example through implementation of gender quotas and provision of support to civil society groups.
Mass Limits on Neutralino Dark Matter

description: We set an upper limit on the mass of a supersymmetric neutralino dark matter particle using the MicrOMEGAS and DarkSUSY software packages and the most recent constraints on relic density from combined WMAP and SDSS data. We explore several different possible scenarios within the MSSM, including coannihilation with charginos and sfermions and annihilation through a massive Higgs resonance, using low energy mass inputs. We find that no coannihilation scenario is consistent with dark matter in observed abundance with a mass greater than 2.5 TeV for a wino--type particle or 1.8 TeV for a Higgsino--type. Contrived scenarios involving Higgs resonances with finely--tuned mass parameters can allow masses as high as 34 TeV. The resulting gamma--ray energy distribution is not in agreement with the recent multi--TeV gamma ray spectrum observed by H.E.S.S. originating from the center of the Milky Way. Our results are relevent only for dark matter densities resulting from a thermal origin.

Publisher: name: Nuovo Giornale di Filosofia della Religione
Year: 2021

description: La lettura della biografia di Madeleine Sémer, convertitasi al Cristianesimo in età adulta e appassionata del pensiero di Friedrich Nietzsche, suggerisce a Guardini un'originale interpretazione della figura intellettuale e spirituale della donna, orgogliosa sino alla fine della propria salute e bellezza, e, insieme, della figura della contemporaneità, nella quale solo un Cristianesimo rinato, riscattato dal sospetto d'essere contrario alla vita e frutto di risentimento, può risultare ancora affascinante e persuasivo. L'articolo, utilizzando anche scritti guardiniani inediti in Italia e il testo della biografia di Sémer, intende mostrare la singolarità della proposta di Guardini, soprattutto ove si considerino i termini del dibattito intorno alla mistica assai vivace negli anni Venti e Trenta del Novecento in ambito teologico e filosofico.

description: The effects that gamma-ray bursts have on their environments is an important and outstanding issue. Dust destruction in particular has long been predicted while observational evidence is difficult to obtain. We examine the evidence for dust destruction by GRB 980703, in which various inconsistent measurements of the host galaxy extinction have been made using the GRB afterglow emission. We construct a spectral energy distribution from nIR to X-ray to measure the extinction at early times and compare this with previous findings. We also construct nIR/optical SEDs at intermediate epochs to examine a previously reported decrease in extinction. The extinction is very high for a GRB host galaxy. The earliest extinction measurement is likely to be lower than previously estimated, and consistent with most later measurements. In a series of SEDs we do not find any evidence of variable extinction. We therefore conclude that there is no clear evidence of dust destruction in this case.

description: The Hubble parameter H0 still not very well measured. Although the Hubble Key Project, Chandra and WMAP gave good estimates, the uncertainties remain quite large. In this brief report, we suggest an original and independent method to derive a lower limit on H0 using the absorption of very high energy gamma-rays by the cosmic infrared background. With conservative hypothesis, we obtain H0>74 km/s/Mpc at the 68% confidence level, which favors the upper end of the intervals allowed by dedicated experiments.

Uomo, natura, cultura. La profezia di Guardini sull'opera in divenire
Creators: name: Grimi, Elisa
Publisher: name: Nuovo Giornale di Filosofia della Religione
Year: 2021

description: Questo studio costituisce una breve riflessione a partire dall'analisi proposta da Guardini in La fine dell'epoca moderna circa la triade natura – soggetto/personalità – cultura. Guardini ripercorre la crisi della modernità rintracciando i punti critici di un'antropologia che sembra talvolta scricchiolare. Parla così di uomo-non- umano, di natura-non-naturale e di cultura-non-culturale (seppur su quest'ultima categoria affermi che la ricerca è ancora in corso). Oggi si può bene osservare ciò che Guardini aveva già sessant'anni fa previsto, e cioè il declino e la trasformazione culturale e sociale, azzardando una definizione più compiuta di ciò che egli aveva sommessamente espresso – poiché non ancora attualizzato – con “non-culturale”. Lontano da una pura analisi linguistica, si osserveranno le implicazioni sociali di tale “rivoluzione” antropologica in riferimento al concetto di “umano”.

Guardini critico del nichilismo

description: L’analisi guardiniana del nuovo orizzonte postmoderno del Cristianesimo si muove nell’ambito di una forte critica della religione – un’eredità dell’Ottocento, specialmente di Nietzsche e, di conseguenza, di Heidegger. Negli anni 1912-1915 Guardini e Heidegger erano compagni di studi a Friburgo, alle lezioni del neokantiano Heinrich Rickert. Negli anni ’30 Guardini leggeva Essere e tempo (1927) e interpretava il nichilismo sia come “morte di Dio” (Nietzsche) sia come mancanza di Dio o della trasformazione ontologico-metafisica di Dio in un essere astratto (Heidegger)1. Da tale interpretazione nacquero i seminari sull’antropologia a Berlino, il cui esito fu l’opera magistrale Mondo e persona (1939)2, pubblicata dopo la cacciata di Guardini a opera dei nazisti dall’università Friedrich-Wilhelm (oggi università Humboldt). Il nichilismo viene brevemente abbozzato nel motto: “Chiudersi nel nulla come limite dell’io”, e nell’acuta critica di Guardini: “L’io come Credo dell’epoca moderna”. È questo il “credo” più pericoloso, perché il nulla è veramente una realtà.

description: Despite being a source of rich information, graphs are limited to pairwise interactions. However, several real-world networks such as social networks, neuronal networks, etc., involve interactions between more than two nodes. Simplicial complexes provide a powerful mathematical framework to model such higher-order interactions. It is well known that the spectrum of the graph Laplacian is indicative of community structure, and this relation is exploited by spectral clustering algorithms. Here we propose that the spectrum of the Hodge Laplacian, a higher-order Laplacian defined on simplicial complexes, encodes simplicial communities. We formulate an algorithm to extract simplicial communities (of arbitrary dimension). We apply this algorithm to simplicial complex benchmarks and to real higher-order network data including social networks and networks extracted using language or text processing tools. However, datasets of simplicial complexes are scarce, and for the vast majority of datasets that may involve higher-order interactions, only the set of pairwise interactions are available. Hence, we use known properties of the data to infer the most likely higher-order interactions. In other words, we introduce an inference method to predict the most likely simplicial complex given the community structure of its network skeleton. This method identifies as most likely the higher-order interactions inducing simplicial communities that maximize the adjusted mutual information measured with respect to ground-truth community structure. Finally, we consider higher-order networks constructed through thresholding the edge weights of collaboration networks (encoding only pairwise interactions) and provide an example of persistent simplicial communities that are sustained over a wide range of the threshold.

progressiva attenuazione del senso dell'essere. L'eredità problematica della religiosità secondo Romano Guardini
Creators: name: Fedeli, Carlo Mario
Publisher: name: Nuovo Giornale di Filosofia della Religione
Year: 2021

description: Il contributo espone la recensione critica della religiosità moderna di Romano Guardini, nei suoi tratti essenziali così come negli aspetti problematici che essa lascia in eredità al post-moderno. Ripercorrendo sinteticamente uno dei lavori più maturi e organici dell’autore, Fenomenologia e teoria della religione, esso intende offrire elementi per verificare se la diagnosi e la prognosi guardiniane risultano ancora oggi valide rispetto allo stato di salute della religiosità nel mondo contemporaneo.

ambiente personale come Umwelt. La ricezione della biologia teorica di Jakob von Uexküll nella teoria della persona di Romano Guardini
Creators: name: Brentari, Carlo
Publisher: name: Nuovo Giornale di Filosofia della Religione
Year: 2021

description: l biologo e filosofo della biologia estone-tedesco Jakob von Uexküll (1864-1944) gioca un ruolo di primo piano nello sviluppo del pensiero etico e antropologico di Romano Guardini. Elementi della biologia teorica di Uexküll entrano in gioco, in particolare, nella determinazione guardiniana del concetto di persona. Se da un lato la persona viene letta da Guardini come una configurazione gestaltica (e qui Guardini si rifà invece all’approccio di Wolfgang Köhler), dall’altro lato essa è vista come istanza formatrice di una sfera individuale del senso e del valore, di un mondo-ambiente originale e irripetibile. In questo secondo aspetto, Guardini sfrutta pienamente le potenzialità del concetto uexkülliano di Umwelt, recependone anche un tratto (la variabilità intra-specifica) spesso ignorato dagli interpreti.

dottrina dell'illuminazione. Romano Guardini interprete di Bonaventura da Bagnoregio
Creators: name: Bozza, Martino
Publisher: name: Nuovo Giornale di Filosofia della Religione
Year: 2021

description: Romano Guardini si occupa del pensiero bonaventuriano solo nella sua giovinezza, tuttavia l'accurata analisi delle opere del Dottore serafico rappresenta una fonte di ispirazione per il prosieguo del suo percorso di pensiero. In particolare appare interessante l'attenta e approfondita riflessione che Guardini sviluppa intorno alla dottrina dell'illuminazione di Bonaventura. Tale dottrina viene recepita e analizzata in una duplice prospettiva. Da un lato infatti viene approfondito come la conoscenza dell'idea sia frutto di una vera e propria illuminazione che procede attraverso la similitudine dell'anima con le idee e con Dio, a sottolineare l'attenzione per la modalità attraverso la quale il rapporto tra Dio e l'uomo debba essere considerato anche un rapporto che struttura e rende possibile la conoscenza. Dall'altro lato vi è tutta una rivalutazione del sentire, la luce indica di fatto una certezza, un'immediatezza che non giunge all'uomo in modo analitico, discorsivo, ma è invece una certezza che deriva dal fatto stesso che il soggetto si sente partecipe di quelle idee, è l'anima stessa che entra in contatto con le idee. Da qui la certezza indubitabile, la sicurezza di avere un giudizio vero perché si è fatta esperienza di quell'idea attraverso l'anima. Si evidenzia dunque una tipologia di conoscenza che non è quella semplicemente empirica, certo il punto di partenza è il mondo sensibile, ma allo stesso tempo la certezza delle idee è un'esperienza dell'anima, che nulla ha di empirico. Questa, allora, l'originalità di una lettura di Bonaventura che sottolinea la rivalutazione del sentire, la rivisitazione del concetto di coscienza come facoltà sapienziale. In questo percorso di veggenza verso la Verità, Guardini evidenzia come il culmine dell'illuminazione che permette l'innalzamento ascetico sostenuto da Bonaventura sia l'azione dell'unico mediatore, il Cristo, solo con questa presenza, dunque, è inverata la possibilità dell'autentica ascesi.
