Les indéterminations augustiniennes. Gilson’s reading of the Augustinian thought
Creators: name: Chiappetta, Federico
Publisher: name: Università degli Studi di Milano
Year: 2016

description: Étienne Gilson ha dedicato numerosi lavori alla riflessione filosofica di Agostino e alla tradizione agostiniana medievale. Lo storico francese ha cercato di rilevare i tratti principali e lo spirito della filosofia agostiniana e si è interessato ai complessi sviluppi dell’agostinismo. Gilson ha introdotto la categoria storiografica delle indeterminazioni agostiniane per esprimere la complessità del pensiero di Agostino: questa filosofia sarebbe caratterizzata da numerose questioni irrisolte dovute al tentativo agostiniano di dare alla filosofia neoplatonica un significato cristiano. In alcuni suoi lavori, Gilson ha sostenuto che la convergenza fra queste indeterminazioni e alcuni sistemi di pensiero, giunti nell’occidente latino fra il XII e il XIII secolo, avrebbe ispirato la cosiddetta riforma tomista. A questo proposito è molto importante un articolo del 1926, Pourquoi saint Thomas a critiqué saint Augustin. L’articolo mostra l’importanza delle indeterminazioni negli studi dello storico: questa intrinseca incompletezza dell’opera di Agostino consentirebbe di comprendere non solo gli sviluppi del pensiero agostiniano, ma anche il pensiero di Tommaso d’Aquino e della scuola domenicana. L’articolo tratteggia, inoltre, l’interpretazione di Gilson del pensiero agostiniano in relazione all’adesione dello storico alla filosofia neoscolastica.

Étienne Gilson devoted several studies to Augustine’s thought and to medieval Augustinian tradition. The French historian attempted to paint the main tracts and the spirit of Augustine’s philosophy and he studied the complex developments of Augustinianism. Gilson introduced the historical category of the indéterminations augustiniennes to express the problematic nature of Augustine’s thought: this philosophy would be characterized by several unexplained questions due to the Augustinian attempt to attach a Christian meaning to the Neoplatonic philosophy. In numerous of his works, Gilson pointed out that the confluence of these indéterminations and some philosophies, penetrated into Latin west during XII-XIII centuries, would have inspired the so-called Thomistic reform. On this subject it is very revealing an essay written in 1926, “Pourquoi saint Thomas a critiqué saint Augustin”. This paper aims to outline the importance of the indéterminations in the Gilsonian studies: this intrinsic incompleteness of the Augustinian texts would allow understanding not only the Augustinian tradition, but also Thomas Aquinas’ philosophy and Dominican thought. This article outlines Gilson’s reading of the Augustinian thought with regard to Gilsonian Neo-Scholastic philosophy.

description: Proponents tout the positive incentive-to-innovate effects of intellectual property rights (IPRs), while others maintain that the expanding subject matter and geographical extent of IPRs are stifling crop research, especially research and development (R&D) dealing with developing-country crop concerns. Much of this debate relies on anecdotes and misleading or incomplete evidence on the extent and nature of the IPRs pertaining to crop technologies, including the jurisdictional extent of the property rights and their practice. In this paper we review the evidence on the scope of agricultural R&D worldwide, provide new data on the structure of crop-related IPRs, and summarize trends on the uptake of proprietary bioengineered crops.

Traduzione tradizione innovazione
Creators: name: Pullano, Francesca
Publisher: name: Università degli Studi di Milano
Year: 2016

description: Che cosa vuol dire tradurre? Con questa interessante domanda, Umberto Eco inizia la sua riflessione sulla traduzione. Quando si traduce, in gioco non c'è solamente il testo ma un intero mondo possibile; il compito del traduttore è fare un'ipotesi su questo mondo possibile e la traduzione funzionerà meglio tanto più l’ipotesi risulterà plausibile. Per quanto la traduzione sia ben riuscita, non si arriva mai a dire la stessa cosa, si può solo dire quasi la stessa cosa.

Tradurre un capolavoro di un’epoca lontana, tenendo presente la filosofia contemporanea, è un modo di rapportarsi alla tradizione, farla propria e rinnovarla. Si possono confrontare alcune traduzioni e discuterne la correttezza filologica e le implicazioni teoriche, prendendo come esempio un brevissimo passo delle Confessioni di Agostino, particolarmente importante e ricco di significati: interrogatio mea intentio mea et responsio eorum species eorum. È significativo non solo il confronto tra diverse traduzioni italiane, ma anche tra alcune traduzioni in lingue diverse dall’italiano. In alcuni casi le traduzioni un po’più libere e audaci, risultano più efficaci rispetto a quelle più semplici e letterali.

What does to translate means? With this interesting question, Umberto Eco begins his consideration about the translation. When translating, at stake it is not only the text but an entire possible world; the translator's task is make a hypothesis about this possible world, and if the hypothesis is credible the translation will work well. Although the translation is successful, you never manage to say the same thing, you can only say almost the same thing.

Translating a masterpiece of bygone age, keeping in mind the contemporary philosophy, is a way of relating to tradition, make it own and renew it. You can compare a few translations and discuss the correct philological and theoretical implications, taking as an example a very short passage from the Confessions of Augustine, which is particularly important and meaningful: interrogatio mea intentio mea et responsio eorum species eorum. It is significant not only comparing different Italian translations, but also comparing some translations in other languages. Sometimes the translations a bit more free and brave are more effective than the most simple and literal.

Seismic performance of braced timber frames
Creators: name: Popovski, Marjan
Publisher: name: University of British Columbia
Year: 2009

description: Braced timber frames are efficient lateral load resistance systems in buildings where large open spaces are required, and the more commonly used timber shear wall systems cannot be utilized. Braced timber frames allow for flexibility in the design and use the wood in its strongest direction - parallel to grain in tension or compression. For application in high-risk earthquake zones, however, the ductility of the system is a concern, since energy absorption is typically limited to the connection region. This study focused on seismic behaviour of braced timber frames with particular emphasis on investigating the influence of different connection details on the overall stiffness, strength and seismic energy absorption capacity of the frame. Monotonic tension and cyclic quasi-static tests were conducted on a variety of connections typically used in braced timber frames, utilizing different diameter bolts and high strength glulam rivets with steel side plates. Shake table tests were subsequently conducted on a selected number of single storey braced frames with some of the connections previously tested and on a two storey braced timber frame model with riveted connections. The experimental results from quasi-static tests and shake table tests were used to establish and verify non-linear analytical models representing the load-deformation behaviour of different connections. These hysteresis curves were then introduced in analytical braced frame models. These models were used in a number of non-linear static and dynamic analyses to determine the response of braced frames to the input of five different records from previous earthquakes. From these analyses it was possible to determine the influence of different connection details on the seismic response of the selected types of braced timber frames. Based on the results from the analytical part of the study, an estimate was made on the appropriate force modification factors (R-factors) for earthquake resistant design of braced timber frames, as used in the National Building Code of Canada. Finally, some design and construction recommendations are discussed to inform the reader of the details required to obtain an adequate seismic performance. Possible ways of improving the seismic behaviour of braced timber frames are presented as well.

description: Lo scopo del presente contributo è quello di riflettere da un punto di vista storiografico sull’interesse che la recente filosofia analitica ha mostrato nei confronti del pensiero tomista. Dopo aver contestualizzato la nascita di una vera e propria corrente denominata Tomismo analitico e averla adeguatamente definita, indicherò come essa si sia potuta sviluppare attraverso l’uso del criterio di ricorsività e di cinque massime storiografiche. Nella seconda parte prenderò in considerazione un caso particolare, analizzando la Serie metafisica tomista e metafisica analitica attualmente in corso di pubblicazione presso la case editrice Carocci. Concluderò sottolineando come lo studio di domande ricorrenti, la commensurabilità dei paradigmi e una notevole consapevolezza storica siano i presupposti che rendono possibile il confronto tra due ontologia appartenenti a due epoche storiche così distanti.

The aim of this paper is to ponder over the interest that more recent analytic philosophy has displayed for Thomism from a historiographical point of view. In the first section, the current called Analytical Thomism will be defined, and its origin will be adequately contextualized in order to underline how its existence and relevance are possible thanks to the use of the criterion of recursivity and of five historiographic precepts. In the following sections, a distinctive case will be taken into consideration; in fact the Collection of Thomistic Metaphysics and Analytic Metaphysics now published by Carocci will be analysed. In the conclusion, I will critically expound the posited criteria that make it possible to compare these two ontologies belonging to so different historical backgrounds: to pay attention to recurring requests, to consider different paradigms as commensurable as well as a great historic awareness.

description: L’analisi informatica di testi filosofici, la creazione di database, ipertesti o edizioni elettroniche non costituiscono più unicamente una ricerca di frontiera, ma sono da molti anni una risorsa preziosa per gli studi umanistici. Ora, non si tratta di richiedere alle macchine un ulteriore sforzo per comprendere il linguaggio umano, quanto piuttosto di perfezionare gli strumenti affinché esse possano essere a tutti gli effetti collaboratori di ricerca. Questo articolo è concepito come il resoconto di un esperimento finalizzato a documentare come le associazioni lessicali di un gruppo selezionato di testi medievali possa offrire qualche suggerimento in merito ai loro contenuti teorici.

Computer analysis of texts, creation of databases hypertexts and digital editions are not the final frontier of research anymore. Quite the contrary, from many years they have been representing a significant contribution to medieval studies. Therefore, we do not mean to make the computer able to grasp the meaning of human language and penetrate its secrets, but rather we aim at improving their tools, so that they will become an even more efficient equipment employed in research activities. This paper is thought as a sort of technical report with the proposed task to verify if an automatic identification of some word associations within a selected groups of medieval writings produces suggestions on the subject of the processed texts, able to be used in a theoretical inquiry.

description: The transient stability of traditional power systems is concerned with the ability of generators to stay synchronized with the positive-sequence voltage of the network, whether for symmetrical or asymmetrical faults. In contrast, both positive- and negative-sequence synchronizations should be of concern for inverter-based generation (IBG) under asymmetrical faults. This is because the latest grid codes stipulate that IBG should inject dual-sequence current when riding through asymmetrical faults. Currently, much less is known about the synchronization stability during asymmetrical faults. This significantly differs from the positive-sequence synchronization alone because the coupled dual-sequence synchronization is involved. This paper aims to fill this gap. Considering the sequence coupling under asymmetrical faults, the dual-sequence synchronization model of IBG is developed. Based on the model, the conditions that steady-state equilibrium points should follow are identified. The conditions throw light on the possible types of synchronization instability, including the positive-sequence dominated instability and the negative-sequence dominated one. For different types of instability, the dominant factors are analyzed quantitatively, which are reflected by the limit on the current injection amplitude. Exceeding the limit will lead to the loss of both positive- and negative-sequence synchronizations. The model and the analysis are verified by simulations and hardware-in-the-loop experiments.
The imprint of ultralight vector fields on gravitational wave propagation

description: We study the effects of ultralight vector field (ULVF) dark matter on gravitational-wave propagation. We find that the coherent oscillations of the vector field induce an anisotropic suppression of the gravitational-wave amplitude as compared to the $Λ$CDM prediction. The effect is enhanced for smaller vector field masses and peaks for modes around $k=H_0/\sqrt{a(H=m)}$. The suppression is negligible for astrophysically generated gravitational waves but could be sizeable for primordial gravity waves. We discuss the possibility of detecting such an effect on the tensor power spectrum with future CMB B-mode polarization detectors. We find that for the sensitivity of the upcoming LiteBIRD mission, the correction to the tensor power spectrum at decoupling time could be distinguishable from that of $Λ$CDM for ULVF masses $m\lesssim 10^{-26}$ eV and sufficiently large abundances.

description: Maxwell and Dirac fields in Friedmann-Robertson-Walker spacetime is investigated using the Newman-Penrose method. The variables are all separable, with the angular dependence given by the spin-weighted spherical harmonics. All the radial parts reduce to the barrier penetration problem, with mostly repulsive potentials representing the centrifugal energies. Both the helicity states of the photon field see the same potential, but that of the Dirac field see different ones; one component even sees attractive potential in the open universe. The massless fields have the usual exponential time dependencies; that of the massive Dirac field is coupled to the evolution of the cosmic scale factor $a$. The case of the radiation filled flat universe is solved in terms of the Whittaker function. A formal series solution, valid in any FRW universe, is also presented. The energy density of the Maxwell field is explicitly shown to scale as $a^{-4}$. The co-moving particle number density of the massless Dirac field is found to be conserved, but that of the massive one is not. Particles flow out of certain regions, and into others, creating regions that are depleted of certain linear and angular momenta states, and others with excess. Such current of charged particles would constitute an electric current that could generate a cosmic magnetic field. In contrast, the energy density of these massive particles still scales as $a^{-4}$.

description: The transfer learning of a neural network is one of its most outstanding aspects and has given supervised learning with neural networks a prominent place in data science. Here we explore this feature in the context of strongly interacting many-body systems. Through case studies, we test the potential of this deep learning technique to detect phases and their transitions in frustrated spin systems, using fully-connected and convolutional neural networks. In addition, we explore a recently-introduced technique, which is at the middle point of supervised and unsupervised learning. It consists in evaluating the performance of a neural network that has been deliberately "confused" during its training. To properly demonstrate the capability of the "confusion" and transfer learning techniques, we apply them to a paradigmatic model of frustrated magnetism in two dimensions, to determine its phase diagram and compare it with high-performance Monte Carlo simulations.

Entropy and Area in Loop Quantum Gravity

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Black hole thermodynamics suggests that the maximum entropy that can be contained in a region of space is proportional to the area enclosing it rather than its volume. I argue that this follows naturally from loop quantum gravity and a result of Kolmogorov and Bardzin' on the the realizability of networks in three dimensions. This represents an alternative to other approaches in which some sort of correlation between field configurations helps limit the degrees of freedom within a region. It also provides an approach to thinking about black hole entropy in terms of states inside rather than on its surface. Intuitively, a spin network complicated enough to imbue a region with volume only lets that volume grow as quickly as the area bounding it.

description: We exploit the theoretical strength of the supervariable and Becchi-Rouet-Stora-Tyutin (BRST) formalisms to derive the proper (i.e. off-shell nilpotent and absolutely anticommuting) (anti-)BRST symmetry transformations for the reparameterization invariant model of a non-relativistic (NR) free particle whose space $(x)$ and time $(t)$ variables are function of an evolution parameter $(τ)$. The infinitesimal reparameterization (i.e. 1D diffeomorphism) symmetry transformation of our theory is defined w.r.t. this evolution parameter $(τ)$. We apply the modified Bonora-Tonin (BT) supervariable approach (MBTSA) as well as the (anti-)chiral supervariable approach (ACSA) to BRST formalism to discuss various aspects of our present system. For this purpose, our 1D ordinary theory (parameterized by $τ$) is generalized onto a $(1, 2)$-dimensional supermanifold which is characterized by the superspace coordinates $Z^M = (τ, θ, \barθ)$ where a pair of Grassmannian variables satisfy the fermionic relationships: $θ^2 = {\barθ}^2 = 0, \, θ\,\barθ+ \barθ\,θ= 0$ and $τ$ is the bosonic evolution parameter. In the context of ACSA, we take into account only the (1, 1)-dimensional (anti-)chiral super sub-manifolds of the general (1, 2)-dimensional supermanifold. The derivation of the universal Curci-Ferrari (CF)-type restriction, from various underlying theoretical methods, is a novel observation in our present endeavor. Furthermore, we note that the form of the gauge-fixing and Faddeev-Popov ghost terms for our NR and non-SUSY system is exactly same as that of the reparameterization invariant SUSY (i.e. spinning) and non-SUSY (i.e. scalar) relativistic particles. This is a novel observation, too.

description: The next generation of gravitational-wave observatories will reach low frequency limits on the orders of a few Hz, thus enabling the detection of gravitational wave signals of very long duration. The run time of standard parameter estimation techniques with these long waveforms can be months or even years, making it impractical with existing Bayesian inference pipelines. Reduced order modeling and reduced order quadrature integration rule have recently been exploited as promising techniques that can greatly reduce parameter estimation computational costs. We describe a Python-based reduced order quadrature building code, PyROQ, which builds the reduced order quadrature data needed to accelerate parameter estimation of gravitational waves. We present the first bases for the IMRPhenomXPHM waveform model of binary-black-hole coalescences, including subdominant harmonic modes and precessing spins effects. Furthermore, the code infrastructure makes it directly applicable to the gravitational wave inference for space-borne detectors such as the Laser Interferometer Space Antenna (LISA).

Channel assignment schemes in cellular communication systems
Creators: name: Chong, Peter H. J.
Publisher: name: University of British Columbia
Year: 2009

description: The demand for mobile cellular communications services is increasing rapidly. Much effort is being devoted to the design of techniques to support a large number of users in a limited radio frequency band. One approach is to employ a more efficient channel assignment scheme. Packet-switching will also be used in future mobile cellular systems since it is expected that most of the traffic sources carried in future systems will be very bursty due to the combination of voice, data and video communications services. The objective of this thesis is to study various types of channel assignment methods, fixed channel assignment (FCA) and dynamic channel assignment (DCA), in order to improve capacity in current ox future cellular systems. The performance of a Reuse Partitioning (RP) system using FCA (FRP) with and without handoff is first analyzed. RP uses n cluster sizes instead of one as used in a conventional FCA system. It is shown that the performance of FCA can be substantially improved by using RP. With mobile users, the capacity improvement of FRP relative to FCA decreases with the average handoff rate. A new distributed DCA scheme, known as DCA with interference information (DCA-WI), is then proposed and studied by computer simulation. In this scheme, a base station in a cell assigns a channel to a call based on the channel information in its neighboring cells. It is shown that DCA-WI outperforms previous channel assignment schemes in both uniform and nonuniform traffic distributions. To support bursty traffic, FCA and DCA schemes used in conjunction with packet reservation multiple access (PRMA) and PRMA++ in a packet-switched voice cellular system are studied. Two measurement-based protocols, DCA/PRMA and DCA/PRMA++, are studied to cope with the highly unpredictable and time-varying microcellular environment. A channel reassignment technique is suggested which reduces the number of packets lost due to out-of-cell interference during speech talkspurts. It is shown that channel reassignment can improve the performance significantly.

description: Physical qubits in experimental quantum information processors are inevitably exposed to different sources of noise and imperfections, which lead to errors that typically accumulate hindering our ability to perform long computations reliably. Progress towards scalable and robust quantum computation relies on exploiting quantum error correction (QEC) to actively battle these undesired effects. In this work, we present a comprehensive study of crosstalk errors in a quantum-computing architecture based on a single string of ions confined by a radio-frequency trap, and manipulated by individually-addressed laser beams. This type of errors affects spectator qubits that, ideally, should remain unaltered during the application of single- and two-qubit quantum gates addressed at a different set of active qubits. We microscopically model crosstalk errors from first principles and present a detailed study showing the importance of using a coherent vs incoherent error modelling and, moreover, discuss strategies to actively suppress this crosstalk at the gate level. Finally, we study the impact of residual crosstalk errors on the performance of fault-tolerant QEC numerically, identifying the experimental target values that need to be achieved in near-term trapped-ion experiments to reach the break-even point for beneficial QEC with low-distance topological codes.

description: We study eta meson properties in the infinite nuclear matter and in atomic nuclei with an emphasis on effects of the eta coupling to N*(1535)--nucleon-hole modes. The N*(1535) resonance, which dominates the low-energy eta-nucleon scattering, can be seen as a chiral partner of the nucleon. The change of the chiral mass gap between the N* and the nucleon in a nuclear medium has an impact on the properties of the eta-nucleus system. If the N*-nucleon mass gap decreases with a density increase (chiral symmetry restoration) the calculations show the existence of the resonance state at the energy about 60 MeV and two bound eta-nucleus states with the binding energies about -80 MeV. These states can have strong effect on predicted cross sections of the ^12C (gamma,p) ^11B reaction with eta-meson production.

description: Für Falko Peschel (2012, S. 71) enthält ein Arbeitsblatt „vorwiegend rein reproduktive Aufgabenstellungen mit festgelegter Zugangsmöglichkeit zum Stoff (statt entdeckendes oder herausforderndes Lernen zu unterstützen).“ Die empirische Forschung dieser Masterarbeit ist viergeteilt und gründet auf einer Sammlung von Arbeitsblättern aus den Fachbereichen Deutsch, Mathematik, Sachunterricht und Kunst. Eine erste Auswertung ergab, dass Arbeitsblätter vorzugsweise in den MINT-Fächern zum Einsatz kamen, wobei der Sachunterricht den höchsten prozentualen „Arbeitsblatteinsatz“ zu verzeichnen hatte. Dieser Bereich wurde zur Stichprobenauswahl bestimmt und ein geschlossener Fragebogen für eine weitere dreiteilige Analyse entwickelt. Die Analyse basiert auf den Kriterien der folgenden Bereiche, die im Theorieteil dieser Arbeit eingehend behandelt werden: a) den grundlegenden Gestaltungskriterien des Layouts und Designs, b) den Modellvorstellungen zum Textverstehen und c) der Unterscheidung von Arbeitsblättern nach ihrer Art und Funktion. Die Auswertung hat ein positives Bild im Bereich der Umsetzung typografischer Empfehlungen gezeigt. Ein negativer Trend konnte bezüglich der sachunterrichtlichen „Arbeitsblatt-Praxis“ im Kontext des entdeckenden und forschenden Lernens festgestellt werden. Die Arbeitsblätter waren von ihrer Art und Funktion her kaum für ein solches Lernen ausgelegt und es bestätigte sich eher Peschels oben genannte Ansicht einer vorwiegend reproduktiven Aufgabenstellung.

description: I review several central open questions concerning GRB Jets. 1) I discuss a new estimates of the beaming correction for the rate of GRBs ~ 75 +- 20. 2) I discuss the universal structured jet (USJ) model and conclude that while jets might be structured they are less likely to be universal. 3) I discuss recent observations of a sideways expansion of a GRB afterglow and compare these with current hydrodynamics simulations of jet evolution. 4) I discuss the implications of resent outliers to the energy-angle relation.

description: We generalize Lindeberg's proof of the central limit theorem to an invariance principle for arbitrary smooth functions of independent and weakly dependent random variables. The result is applied to get a similar theorem for smooth functions of exchangeable random variables. This theorem allows us to identify, for the first time, the limiting spectral distributions of Wigner matrices with exchangeable entries.

description: We report systematic, high-precision measurements of the low-T (down to 70 mK) thermal conductivity κof YBa_{2}Cu_{3}O_{y}, La_{2-x}Sr_{x}CuO_{4} and Bi_{2}Sr_{2}CaCu_{2}O_{8+δ}. Careful examinations of the Zn- and hole-doping dependences of the residual thermal conductivity κ_{0}/T, as well as the in-plane anisotropy of κ_{0}/T in Bi_{2}Sr_{2}CaCu_{2}O_{8+δ}, indicate a breakdown of the universal thermal conductivity, a notable theoretical prediction for d-wave superconductors. Our results point to an important role of electronic inhomogeneities, that are not considered in the standard perturbation theory for thermal conductivity, in the under- to optimally-doped regime.

description: Effects of resonant acoustic phonon scattering on magnetoresistivity are examined in two-dimensional electron systems at low temperatures by using a balance-equation magnetotransport scheme direct controlled by the current. The experimentally observed resonances in linear resistivity are shown to result from the conventional bulk phonon modes in a GaAs-based system, without invoking leaky interface phonons. Due to quick heating of electrons, phonon resonances can be dramatically enhanced by a finite bias current. When the electron drift velocity increases to the speed of sound, additional and prominent phonon resonance peaks begin to emerge. As a result, remarkable resistance oscillation and negative differential resistivity can appear in nonlinear transport in a modest mobility sample at low temperatures, which is in agreement with recent experiments.

description: We study algebraic neural networks (AlgNNs) with commutative algebras which unify diverse architectures such as Euclidean convolutional neural networks, graph neural networks, and group neural networks under the umbrella of algebraic signal processing. An AlgNN is a stacked layered information processing structure where each layer is conformed by an algebra, a vector space and a homomorphism between the algebra and the space of endomorphisms of the vector space. Signals are modeled as elements of the vector space and are processed by convolutional filters that are defined as the images of the elements of the algebra under the action of the homomorphism. We analyze stability of algebraic filters and AlgNNs to deformations of the homomorphism and derive conditions on filters that lead to Lipschitz stable operators. We conclude that stable algebraic filters have frequency responses -- defined as eigenvalue domain representations -- whose derivative is inversely proportional to the frequency -- defined as eigenvalue magnitudes. It follows that for a given level of discriminability, AlgNNs are more stable than algebraic filters, thereby explaining their better empirical performance. This same phenomenon has been proven for Euclidean convolutional neural networks and graph neural networks. Our analysis shows that this is a deep algebraic property shared by a number of architectures.

description: The real-estate market is "where" a multiplicity of economic, cultural, social and demographic factors are synthesised with respect to choices regarding the qualitative and locational aspects of a property. The spatial analysis of the real-estate market and, in particular, of the factors which contribute to determining prices, is a very useful instrument in outlining the geography of the economic development of vast areas. The aim of the paper is the construction of a simulation model, on a spatial level, of real-estate values with reference to the housing market in the urban area of the city of Treviso (I). The model was built using a neural network which gives the possibility of analysing the marginal contribution of single real-estate characteristics independently of the a priori choice of the interpolation function; at the same time it works well even in the presence of statistical correlation among the explicative variables, a serious drawback in multiple regression models. The work is divided into several parts. First, a synthetic picture of the real-estate market of the area studied has been drawn up with reference to the main conditioning factors. Then the problem of the selection of a neural network model for the appraisal of property values is presented. Finally, there is the description of the procedure for the spatialization of obtained results from the neural model for the definition of a values map. The results shows the notable interpretative and predictive capacity of the neural model and it seems very useful in appraisals. Furthermore, the mapping of value fluctuations enables first-hand verification of the "goodness" of the assessed model and its capacity to portray the real situation. The general approach presented seems, therefore, useful both as an instrument of support for urban and territorial planning, as well as a permanent monitoring system of the real-estate market with the aim of creating an informative system of support for the analysis of real-estate investment.

Justification of the Asymptotic Coupled Mode Approximation of Out-of-Plane Gap Solitons in Maxwell Equations

description: In periodic media gap solitons with frequencies inside a spectral gap but close to a spectral band can be formally approximated by a slowly varying envelope ansatz. The ansatz is based on the linear Bloch waves at the edge of the band and on effective coupled mode equations (CMEs) for the envelopes. We provide a rigorous justification of such CME asymptotics in two-dimensional photonic crystals described by the Kerr nonlinear Maxwell system. We use a Lyapunov-Schmidt reduction procedure and a nested fixed point argument in the Bloch variables. The theorem provides an error estimate in $H^2(\mathbb R^2)$ between the exact solution and the envelope approximation. The results justify the formal and numerical CME-approximation in [Dohnal and Dörfler, Multiscale Model. Simul., p. 162-191, 11 (2013)].

description: Equine influenza (EI) is a highly contagious acute respiratory disease of equines that is caused mainly by the H3N8 subtype of influenza A virus. Vaccinating horses against EI is the most effective strategy to prevent the infection. The current study aimed to compare the kinetics of EI-specific humoral- and cell-mediated immunity (CMI) in horses receiving either identical or mixed vaccinations. Two groups of horses were previously (six months prior) vaccinated with either Calvenza 03 EIV EHV® (G1) or Fluvac Innovator® (G2) vaccine. Subsequently, both groups received a booster single dose of Calvenza 03 EIV EHV®. Immune responses were assessed after 10 weeks using single radial hemolysis (SRH), virus neutralization (VN), and EliSpot assays. Our results revealed that Calvenza-03 EIV/EHV®-immunized horses had significantly higher protective EI-specific SRH antibodies and VN antibodies. Booster immunization with Calvenza-03 EIV/EHV® vaccine significantly stimulated cell-mediated immune response as evidenced by significant increase in interferon-γ-secreting peripheral blood mononuclear cells. In conclusion, Calvenza-03 EIV/EHV® vaccine can be safely and effectively used for booster immunization to elicit optimal long persisting humoral and CMI responses even if the horses were previously immunized with a heterogeneous vaccine.
