description: L'interesse per lo studio delle dinamiche economiche regionali è stato a lungo ostacolato dalla carenza di dati utilizzabili. In questo lavoro si descrive la costruzione di una banca dati dello stock di capitale, sia privato che pubblico, nelle regioni italiane. Entrambi sono costruiti con la tecnica dell'inventario permanente. Il capitale privato - disponibile dal 1970 al 1995 per tre tipologie di beni è costruito utilizzando le serie degli investimenti fissi per branca utilizzatrice dell'industria, ottenute a partire da dati di diversa provenienza. L'investimento pubblico aggregato è ripartito per regione e per tipologia di bene utilizando i dati contenuti nella pubblicazione annuale dell'ISTAT ''Opere Pubbliche''. Utilizzando i dati di investimento così ottenuti, si calcolano le stime del capitale publico regionale, per nove categorie di beni, per gli anni dal 1970 al 1996.

description: We report the discovery of a redshift 1.71 supernova in the GOODS North field. The Hubble Space Telescope (HST) ACS spectrum has almost negligible contamination from the host or neighboring galaxies. Although the rest frame sampled range is too blue to include any Si ii line, a principal component analysis allows us to confirm it as a Type Ia supernova with 92% confidence. A recent serendipitous archival HST WFC3 grism spectrum contributed a key element of the confirmation by giving a host-galaxy redshift of 1.713 +/- 0.007. In addition to being the most distant SN Ia with spectroscopic confirmation, this is the most distant Ia with a precision color measurement. We present the ACS WFC and NICMOS 2 photometry and ACS and WFC3 spectroscopy. Our derived supernova distance is in agreement with the prediction of LambdaCDM.

description: We use first-principles calculations to extract two essential microscopic parameters, the charge-transfer energy and the inter-cell oxygen-oxygen hopping, which correlate with the maximum superconducting transition temperature $\Tcmax$ across the cuprates. We explore the superconducting state in the three-band model of the copper-oxygen planes using cluster Dynamical Mean-Field Theory. We find that the variation in the charge-transfer energy largely accounts for the empirical trend in $\Tcmax$, resolving a long-standing contradiction with theoretical calculations.

description: We investigate the properties of a single photon generated by a solid-state emitter subject to strong pure dephasing. We employ a model in which all the elements of the system, including the propagating fields, are treated quantum mechanically. We analytically derive the density matrix of the emitted photon, which contains full information about the photon, such as its pulse profile, power spectrum, and purity. We visualize these analytical results using realistic parameters and reveal the conditions for maximizing the purity of generated photons.

description: This paper reports a novel MMIC sampler based on NLTL technology which has been designed using the Philips ED02AH process. The sampling MMIC can be used to measure waveforms in the (3->34) GHz bandwidth. A tapered microstrip based NLTL pulse generator has been combined with a diode-resistor bridge to minimize on GaAs real estate compared to CPW methodology. The advantage of the designed sampling MMIC is wide bandwidth, compressed size and consequently lower cost. The sampling MMIC finds application in sampling oscilloscopes and Time Domain Reflectometers (TDRs). A CPW based NLTL shock wave generator has also been designed for comparison based on bonding several MMIC NLTL samples together.

description: A new approach, which takes into account both traps and thermal phenomena is proposed for the accurate modeling of deviations between static and dynamic (e.g., pulsed) drain current characteristics in III-V FETs. The model, which is based on the well known "backgating" concept, can easily be identified on the basis of conventional static drain current characteristics and small-signal, low-frequency S parameters. In the paper, the model formulation is developed along with some hints on its implementation in commercially available CAD tools for HB simulations. Experimental validation, consisting of comparisons between simulated and measured pulsed drain current characteristics, is also provided.
Properties comparison of North American manufactured particleboard and medium density fiberboard

Publisher: name: University of British Columbia
Year: 2013

description: A survey of Canadian and US particleboard (PB) and medium density fiberboard (MDF) manufacturers was performed to identify potential candidates for the mechanical and physical properties comparison study. Sixty-three plants across Canada and the United States were contacted and 19 plants participated in the survey. In order to obtain and compare data on mechanical and physical properties of boards from PB and MDF manufacturers, samples were collected from 10 different manufacturing facilities across Canada and the United States (5 PB and 5 MDF). The performed tests included internal bond (IB), bending and elastic moduli (MOR/MOE), thickness swell (TS), linear expansion (LE), vertical density profile (VDP), and face and edge screw withdrawal resistance (SWR). Each manufacturing facility provided 5 full-sized (2440 by 1220 mm) panels that were tested according to North American standards. For particleboard, 4 out of 5 press lines exceeded the American National Standards Institute (ANSI) A208.1-2009 recommendation for IB. Only one of the tested particleboard sets reached the recommended ANSI standard for MOR. Results for the edge SWR showed that none of the tested particleboard manufacturers reached the ANSI recommended value. For MDF, all but one press line exceeded the ANSI standard A208.2-2009 recommended minimum value for MOE. The results for the modulus of rupture for MDF showed two manufacturers exceeding the recommended value, and three failing to meet the recommended value.

description: The solution to the problem of transconductance compression in HEMT devices can be found by means of a new continuous drain-source current (Ids) model. The proposed model is able to reproduce the global I/V device behaviour under both static DC and dynamic pulsed operating conditions with an excellent fitting in all I/V regions, even in the case of using low and medium power HEMT devices. Being able of reproducing second and third order derivatives, the proposed model is also adequate for describing the nonlinear small-signal performance of these devices. Comparisons between experimental and simulated results, using the proposed model and other well-known models, demonstrate the validity of the new Ids model for various gate widths, technologies and gate peripheries.

Comparison between intermodulation distortion prediction capabilities of the COBRA model and of other non-linear FET models

description: The paper presents results from a study carried out on two FET processes, to demonstrate the enhanced prediction capabilities of the general-purpose FET model COBRA [I], to predict the intermodulation distortion (IMD) characteristics of micro-wave and mm-wave FETs, in comparison with other traditional large-signal models. The first, second and third order derivatives of the COBRA I/V model function are analysed and compared with the corresponding functions for the Statz-Raytheon and a modified Materka model. For the COBRA model case, these derivatives are shown to be continuous over the entire bias plane and in agreement with experimental results previously presented in literature for similar devices and extracted from harmonic measurements. In the case of the other two models, the high-order derivatives are described less accurately, especially around critical bias regions such as knee, pinch-off or soft breakdown. A sequence of two-tone (IMD) large-signal test results are presented for the case of a 0.2um PHEMT process designed for mm-wave applications, and operating in four different bias conditions. The results prove the advantages of the COBRA model in comparison with the other two in predicting high order IM products.

description: We carry out a high-precision Monte Carlo study of the shortest-path fractal dimension $\dm$ for percolation in two and three dimensions, using the Leath-Alexandrowicz method which grows a cluster from an active seed site. A variety of quantities are sampled as a function of the chemical distance, including the number of activated sites, a measure of the radius, and the survival probability. By finite-size scaling, we determine $\dm = 1.130 77(2)$ and $1.375 6(6)$ in two and three dimensions, respectively. The result in 2D rules out the recently conjectured value $\dm=217/192$ [Phys. Rev. E 81, 020102(R) (2010)].

description: We focus on the ongoing and future observations for both the 21 cm line and the CMB B-mode polarization produced by a CMB lensing, and study their sensitivities to the effective number of neutrino species, the total neutrino mass, and the neutrino mass hierarchy. We find that combining the CMB observations with future square kilometer arrays optimized for 21 cm line such as Omniscope can determine the neutrino mass hierarchy at 2 sigma. We also show that a more feasible combination of Planck + POLARBEAR and SKA can strongly improve errors of the bounds on the total neutrino mass and the effective number of neutrino species to be Delta Sigma m_nu ~ 0.12 eV and Delta N_nu ~ 0.38 at 2 sigma.

description: The trend in modern communications and radar systems is to move the analog-to digital interface as far forward in the signal path as possible toward the antenna or sensor. Moving the digital interface forward in the signal path eliminates stages of downconversion and analog filtering that are bulky, expensive, drift with temperature, and require calibration. Ultra-fast device technologies are required to perform direct analog-to-digital conversion on radio frequency (RF) or intermediate frequency (IF) signals that enables moving the digital interface forward in the signal path. This paper describes the performance limits of current analog-to-digital converters (ADCs) and shows how the ultra-fast performance of InP HBT technology is extending the performance of ADCs to higher levels to enable all digital approaches to communications receivers.

description: This paper gives a twistor-string formulation for all tree amplitudes of Einstein (super-)gravities for N=0 and 4. Formulae are given with and without cosmological constant and with various possibilities for the gauging. The formulae are justified by use of Maldacena's observation that conformal gravity tree amplitudes with Einstein wave functions and non-zero cosmological constant will correctly give the Einstein tree amplitudes. This justifies the construction of Einstein gravity amplitudes at N=0 from twistor-string theory and is extended to N=4 by requiring the standard relation between the MHV-degree and the degree of the rational curve for Yang-Mills; this systematically excludes the spurious conformal supergravity gravity contributions. For comparison, BCFW recursion is used to obtain twistor-string-like formulae at degree zero and one (anti-MHV and MHV) for amplitudes with N=8 supersymmetry with and without cosmological constant.

description: Nel presente contributo l’A. analizza l’istituto dell’amministrazione di sostegno, introdotto nel nostro ordinamento con la legge 9 gennaio 2004, n. 6, che rappresenta una risposta all’esigenza, sempre più avvertita, di offrire assistenza alle persone disabili. Il lavoro affronta il problema relativo alla distinzione tra la misura di protezione dell’amministrazione di sostegno e quelle ormai desuete dell’interdizione e dell’inabilitazione, per la soluzione del quale vengono presi in esame gli orientamenti espressi dalla Corte costituzionale, dalla Corte di Cassazione e dalla giurisprudenza di merito, nonché le opinioni espresse dalla dottrina. L’A. descrive quindi la categoria dei soggetti deboli e la necessità di offrire piena tutela alle persone svantaggiate, con i loro diritti fondamentali, la loro identità e la loro dignità che non vanno ritagliati su una realtà ristretta e diversa; tutto ciò alla luce dei principi espressi dalla legislazione nazionale e sovranazionale. Il lavoro inoltre prende in considerazione il ricorso per l’istituzione dell’amministrazione di sostegno, con particolare riguardo al ruolo del giudice tutelare, alla scelta dell’amministratore di sostegno e all’oggetto dell’incarico. 
Particolare attenzione è dedicata alle direttive anticipate di trattamenti sanitari, espresse dal beneficiario dell’amministrazione di sostegno.
Firms’ Heterogeneity And Number Of Export Destinations: A Hurdle Negative Binomial Regression Approach

description: Most of the literature on the link between firm’s participation in international markets and firms’ heterogeneity focuses on the choice of firms to export. This paper addresses on an aspect of firms internationalization so far little explored, the choice of the number of export destinations that can be considered as an indicator of the complexity of the export activity. As the outcome variables are a count with an excess of zeros, we operate in a hurdle regression model for count data framework. Besides the variables usually adopted in literature describing firms’ heterogeneity, in order to explore the link  among the firms efficiency in generating profits and the firms internationalization choices, we consider a set of profitability indexes. 
Results we obtain enlighten that the set of the variables related to the decision of exporting and that connected with the number international markets served is different. At first, it seems that not only the larger the number of markets served, the more productive, large and willing to invest is the firm (confirming the features found studying the propensity to export), but also that firms engaged in multiple markets seem to be older, financially stable, and willing to support organizational and managerial innovations. 
By comparing the estimates regarding the propensity to export model and those of the model describing the number of export destinations, some main differences arise. At first the Return on Sales index become significant in the number of destinations model whereas this covariate was not relevant in explaining the propensity to export: it seems that the firms, the more opened to the international markets, are characterized by a better use of investment funds to generate earnings growth. Secondly, in the count model significance has been found for only one type of innovation, the managerial one, indicating that, although the innovation activity seems to be pivotal for exporting, once the firm exports, the change in the managerial and organizational structure become important to align to the more competitive market.

description: Pflanzliche Alkaloide stossen auf grosses Interesse aufgrund ihrer physiologischen Eigenschaften. Stachelmohn Argemone mexicana ist eine pharmazeutisch angewendete Heilpflanze. Sie enthält Alkaloide vom Protoberberin-, Protopin- und Benzophenanthridintyp. Unbeachtet der Fortschritte in der Aufklärung der chemischen Strukturen der Alkaloide, ist die Charakterisierung der Biosynthese dieser Benzylisochinolinalkaloide noch unvollständig. Gründe dafür liegen in der Verzweigung der Biosynthese und in einigen Fällen in der geringen Proteinexpression. In der vorliegenden Arbeit wurde eine EST Bibliothek von Argemone mexicana angelegt. Dies war die Basis für die Isolierung einer FAD abhängigen Oxygenase der Protoberberinbiosynthese. Für eine Beteiligung des Enzymes an der Biosynthese der sich vom Corexime ableitenden Protoberberine spricht dabei die Substratpräferenz des Enzymes für Coreximine, welches auch in der Pflanze nachgewiesen werden konnte. Weitere Enzyme, die funktionell in Spodoptera frugiperda (Sf-9) Zellen exprimiert werden konnten, sind zwei Cytochrom P450 der Stylopinbiosynthese, darunter das bisher noch nicht charakterisierte Methylendioxybrückenbindung formende Enzym (S)-Cheilanthifolinsynthase.
description: Plant alkaloids have attracted much interest owing to their physiological properties. Argemone mexicana is a traditional medicinal plant which contains protoberberine, protopine and benzophenanthridine type alkaloids some of them with medicinal properties. Despite advance in chemical structure elucidation, the biosynthesis of benzylisoquinoline alkaloids is still incompletely characterized, due to the long pathways and in some cases the low expression of enzymes. In the present work, the construction of an EST library from roots of Argemone mexicana, led to the isolation of an FAD dependent oxygenase involved in the biosynthesis of protoberberines. In particular, this enzyme might be involved in the biosynthetic pathway derived from coreximine since this alkaloid was the preferred substrate and was also identified to be present in the plant. Furthermore two cytochromes P450 from the biosynthesis of stylopine, including the missing methylenedioxy bridge forming enzyme (S)-cheilanthifoline synthase were functionally expressed in Spodoptera frugiperda (Sf-9) cells.

In particular, using a quite large dataset based on Industrial Census, we deal with the following aspects: (i) the role of structural change, (ii) the role of convergence and /or persistence of the growth rates, and finally, (iii) the impact of measures of specialisation and of variety on economic growth. The main findings seems to support an idiosyncratic view of the Italian industrial development with respect to the well-established litareature on the topic. In particular, two points emerge: the stability of the model of production specialisation along the period considered, and the role of variety of industrial environment as one of the leading factors in spurring local industrial growth.

description: We study some conformally invariant dynamic ways to construct the Conformal Loop Ensembles with simple loops introduced in earlier papers by Sheffield, and by Sheffield and Werner. One outcome is a conformally invariant way to measure a distance of a CLE(4) loop to the boundary "within" the CLE(4), when one identifies all points of each loop.

description: The issue of the observability of the Lamb shift in systems with non-degenerate energy levels is put to question. To this end, we compute the Lamb shift of such systems in the electromagnetic environment provided by two infinite parallel conducting plates, which is instrumental in demonstrating the existence of the so-called Casimir effect. A formula giving the relative change in the Lamb shift (as compared to the standard one in vacuum) is explicitly obtained for spherical semiconductor Quantum Dots (QD). It is the result of a careful mathematical treatment of divergences in the calculations involving distribution theory, which also settles a controversy on two different expressions in the existing literature. It suggests a possibility of QD non-degenerate energy spectrum fine-tuning for experimental purposes as well as a Gedankenexperiment to observe the Lamb shift in spherical semiconductor quantum dots.

description: Untersucht wurden im Rahmen einer multizentrischen Prävalenzstudie zu Essstörungen die Daten von 359 ambulant behandelten Patienten mit Diabetes mellitus im Alter von 18 bis 65 Jahren (94 Typ-I- und 265 Typ-II-Diabetiker). Als Messinstrument kam das Freiburger Per-sönlichkeitsinventar (revidierte Form - FPI-R) als Persönlichkeits-Struktur-Test zum Einsatz. Bei der Auswertung wurden auch alters- und geschlechtsspezifische Stanine-Werte herange-zogen und Clusteranalysen (5-Cluster) gerechnet. In der Gesamtstichprobe der Studie lagen alle FPI-R-Skalenmittelwerte im unauffälligen Normbereich. Verschiebungen ergaben sich in Richtung Gesundheitssorgen/gesundheits-bewusstes Verhalten (Skala 9). In der geschlechtsspezifischen Auswertung zeigten die weiblichen Probanden eine deutliche Furcht vor Erkrankungen und damit verbunden ein stark gesundheitsbewusstes Verhalten. Die über 45-jährigen Diabetikerinnen hatten den höchsten Anteil angespannter, überforderter Patientinnen. Zudem zeigten besonders die älteren Dia-betikerinnen eine schlechte (HbA1c-Werte 9 - 12 %) und sehr schlechte (> 12 %) Stoffwech-seleinstellung. Mittels Clusteranalyse ergab sich folgender Hinwies: Der einerseits gesundheitsbesorgte, andererseits ehrgeizig-leistungsaktiv-extrovertierte Persönlichkeitstyp charakterisierte eine Gruppe mit erhöhtem HbA1c-Wert.

By means of cluster analysis arose following referred to: on the other hand the ambitious-achievement-activ-extroverted typ of personality on the one hand health-procured characterized a group with increased HbA1c.
A double coset problem for classical groups

description: Let G be a simple algebraic group over an algebraically closed field of characteristic p ≥ 0. In this thesis we address the following problem: classify pairs of closed subgroups H, J ≤ G such that there is a finite numbers of (H, J)-double cosets in G. We restrict our attention to the case where G is a classical group and both H and J are connected. A result of Brundan says that if H and J are maximal reductive then the existence of finitely many (H, J)-double cosets is equivalent to G factorizing as G = HJ. Such factorizations have been classified by Liebeck, Saxl and Seitz. On the other hand if both H and J are parabolic subgroups, by the Bruhat decomposition there are finitely many (H, J)-double cosets. We therefore assume that H is reductive and J is not. Moreover, we only consider the case where H is simple and J is a maximal parabolic. With this setup, the problem has been solved for G = SL(V ) by Guralnick, Liebeck, Macpherson and Seitz. When G = SL(V ), the maximal parabolic subgroups correspond to stabilizers of subspaces, which implies that the problem is equivalent to determining modules for simple algebraic groups with finitely many orbits on subspaces. We deal with the case G = Sp(V ) or G = SO(V ), where the maximal parabolic subgroups are the stabilizers of totally singular subspaces. We do this by classifying all self-dual faithful irreducible modules for simple algebraic groups with finitely many orbits on totally singular subspaces of dimension 1 or 2. Furthermore, we determine a complete list of candidates for simple algebraic groups with finitely many orbits on k-dimensional totally singular subspaces for k > 2. We also prove that when H is simple, k = 1 or k = 2 and V is a faithful self-dual irreducible H-module, there are finitely many orbits on totally singular k-spaces of V if and only if there is a dense orbit. Finally, we extend the results for k = 1 to the case H semisimple and maximal among connected subgroups of G.

description: KIVCET smelter is a modern direct smelting process which has been used to replace conventional sinter/blast furnace technology in pyrometallurgical process of lead and zinc. Although heavy metals including Cd, Pb, Zn, Fe as well as S, O and Cl, are the main elements playing a leading role in the formation of molten phase on the waterwall tubes of the KIVCET waste heat boiler, hot corrosion behavior and electrochemical properties of weld overlay and wrought alloy 625 have not been studied yet in the molten salt environments containing the above-mentioned elements. The present study was carried out to study hot corrosion behavior of the weld overlay and wrought alloy 625 as well as failure mechanism of the weld overlay alloy 625 under the corrosive conditions of the radiant boiler in the KIVCET smelter. It was found that the deposited salt mixtures on the waterwall tubes of the radiant boiler had a strong tendency to form a molten phase at the operating temperature range of the radiant boiler. Presence of the deposited salt mixtures and the formation of the molten phase led to the occurrence of the hot corrosion attack in the waterwall and the ultimate failure of the weld overlay. The dilution and, consequently, the presence of a significant amount of Fe in the weldment composition were the key issues in the alloy 625 weld overlay. High concentrations of sulfur and oxygen in the grain boundaries of the wrought alloy 625 are to blame for the occurrence of the intergranular corrosion together with the internal attack. An electrochemical model (a porous and non-protective barrier layer model) was used to explain the corrosion/electrochemical behavior of the wrought alloy which fit into the obtained EIS data well.
Topological light-matter interactions at the nanoscale: controlling THz frequency light with topological insulator nanostructures

description: Topological nanophotonics combines the high sensitivity of nanophotonic systems with the robustness of topological states, presenting an exciting new platform for both nanotechnological applications and fundamental research in topological light-matter interactions. The work I present in this thesis focuses on topological insulator (TI) nanostructures and their interactions with light, with particular focus on the terahertz (THz) regime. TIs are insulating in their bulk and host symmetry-protected, conducting surface states which are robust against disorder. These surface states manifest as a Dirac cone traversing the bulk band gap. TI nanostructures (all dimensions < 100 nm) exhibit a discretised Dirac cone due to quantum confinement of the topological surface states, with energy levels separated by THz frequencies. Due to their analogy with semiconductor quantum dots and 2D topological insulator quantum dots, I refer to this system as a topological quantum dot (TQD). The results of this thesis are organised thematically into three areas: (i) I expand the current knowledge of TI nanostructure electronic structures, describing the surface states and energy levels for geometries ranging from the infinite nanowire to a flat nanodisk within a single mathematical framework. (ii) I investigate the coupling of TQD states with THz frequency light, including selection rules and the suppression of transitions away from the Dirac point when the TQD is placed in a high quality cavity, allowing for a closed system of energy levels. Using Monte Carlo simulations I demonstrate that a single TQD in a cavity will lase in the THz, with an ultra-low threshold. The creation of robust, low threshold lasers in the THz regime is a crucial frontier in modern applied physics, due to the notorious absence of practical technologies for generating and sensing radiation in the THz gap (0.1-10 THz). I show that thermal photons are abundant enough to pump the system, and present a road map to room-temperature THz lasing with no additional external pumping source. (iii) I describe how the quantised TI surface states modify the bulk properties of the nanostructure via a new polariton mode (the SToP mode) [5], and present the first experimental evidence of the SToP mode. I demonstrate how the SToP mode can be used to manipulate the THz behaviour of light in the environment surrounding a TI nanostructure, by increasing the photonic local density of states by many orders of magnitude. This phenomenon has potential applications in nanotechnology and also presents a new way of probing topological properties of matter using light. I hope that this thesis serves as a guide to students new to the wonderful and interdisciplinary topic of topological nanophotonics, and that my work contributes to a slightly better understanding of topological light-matter interactions at the nanoscale, and the manipulation of THz frequency light.

description: We examine the mode functions of the electromagnetic field on spherically symmetric backgrounds with special attention to the subclass which allows for the foliation as open Friedmann-Lemaitre (FL) spacetime. It is well-known that in certain scalar field theories on open FL background there can exist so-called supercurvature modes, their existence depending on parameters of the theory. Looking at specific open universe models, such as open inflation and the Milne universe, we find that no supercurvature modes are present in the spectrum of the electromagnetic field. This excludes the possibility for superadiabatic evolution of cosmological magnetic fields within these models without relying on new physics or breaking the conformal invariance of electromagnetism.

description: This paper studies the relationship between population ageing and saving formation by Italian households. We use five cross-sectional budget surveys to separately construct the age and cohort profiles of the saving rate. After detrending the data, we isolate the age and cohort effects on saving. Cohort effects show that, in the current Italian population, saving behaviour is markedly different across generations. The estimates obtained on survey data are then used to derive a forecast of the medium and long run tendency of the household saving rate (2000-2050). In the absence of any changes in the saving behaviour of young cohorts, the saving rate falls by 15% at the end of the period. The recent reforms of the pension system could induce the young to increase their saving, but the available empirical evidence leads to a scenario where the effects of the pension reform on the incentive to save and accumulate are low, and may be neutralised by the mechanism of intergenerational transfers. Even in a scenario where the young actually react to the pension reform, the reduction in total household wealth at the end of the life-cycle leads to a decrease in aggregate household saving.
