description: Nel 2009 l'Italia attraversa la più grande crisi economica del secondo dopoguerra. Lo studio di ciò che accade, attraverso uno sguardo attento alle principali variabili congiunturali prodotte nel paese, è fondamentale per capire quali sono state le cause che hanno portato a questa situazione e per dare la possibilità  ai policy maker di limitarne gli effetti in futuro. Ma l'Italia non è un territorio dalle caratteristiche monolitiche, è un aggregato di parti molto diverse fra loro. Analizzando il territorio italiano come insieme delle sue parti, osserveremo le medesime condizioni economiche ripetersi in ogni territorio del paese? L'esperienza ci suggerisce di no. La tesi vuole evidenziare come e quanto la  struttura caratteristica del tessuto produttivo regionale è responsabile anche della  performance economica. La tesi è quindi caratterizzata da due parti. Da un lato si è cercato di analizzare quali siano le differenze nei cicli economici regionali, dall'altro, attraverso l'utilizzo di un sistema di valutazione "fuzzy", si è cercato di ricostruire la natura strutturale delle regioni, al fine di determinare quali siano le specializzazioni che ogni territorio è in grado di mettere in campo. 
La tesi si conclude con un'analisi comparativa degli indici di dissimilarità  tra cicli regionali e nazionale e i livelli sintetici di specializzazione, si è verificato che esiste una relazione forte che lega le caratteristiche strutturali delle regioni alle distanze tra i loro cicli, dimostrando quindi la tesi che struttura regionale e performance economica siano strettamente interconnesse.

description: Imparietula Lindholm, 1925 Imparietula Lindholm, 1925: 30, 39. Type species (by monotypy): Bulimus leucodon L. Pfeiffer, 1846. Forcart (1940: 206) considered Pseudochondrula a synonym of Imparietula, which was followed by Gittenberger (1967: 130-137), Akramowski (1976: 154-158) and Hausdorf (1999: 153). Schileyko (1984: 288, 306) separated Pseudochondrula from Imparietula, which was followed by Bank & Neubert (1998: 81). In his latest edition of the Turkish land snails, Schütt (2010: 97-99) also separated Pseudochondrula from Imparietula, and included the following taxa into the latter genus: altenai (Gittenberger, 1967), pelidne (Biggs, 1946), leucodon (L. Pfeiffer, 1846) (with lasistanicus as a synonym), bre- vior (Mousson, 1876) and ridvani Schütt, 1995. Following a taxonomic revision, Páll-Gergely & Bank (in press) raised lasistanica (Lindholm, 1914) to species level, and excluded brevior as a representative of Imparietula. By doing so, Imparietula has become a genus that is endemic for the northeastern part of Turkey. We here introduce another species to the genus.

Synchrotron-Loss Spectral Breaks in Pulsar-Wind Nebulae and Extragalactic Jets

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Flows of synchrotron-emitting material can be found in several astrophysical contexts, including extragalactic jets and pulsar-wind nebulae (PWNe). For X-ray synchrotron emission, flow times are often longer than electron radiative lifetimes, so the effective source size at a given X-ray energy is the distance electrons radiating at that energy can convect before they burn off. Since synchrotron losses vary strongly with electron energy, the source size drops with increasing X-ray energy, resulting in a steepening of the synchrotron spectrum. For homogeneous sources, this burnoff produces the well-known result of a steepening by 0.5 in the source's integrated spectral index. However, for inhomogeneous sources, different amounts of steepening are possible. I exhibit a simple phenomenological picture of an outflow of relativistic electrons with bulk nonrelativistic flow speed, with transverse flow-tube radius, magnetic-field strength, matter density, and flow velocity all varying as different powers of distance from the injection point. For such a picture, I calculate the value of the spectral index above the break as a function of the power-law indices, and show the possible range of steepenings. I show that these simple calculations are confirmed by full integrations of source luminosity, which also include the spectral "bump" below the break from the accumulation of electrons formerly at higher energies. In many cases, extragalactic jets show X-ray synchrotron emission steeper by more than 0.5 than the radio emission; the same phenomenon is exhibited by many pulsar-wind nebulae. It is possible that source inhomogeneities are responsible in at least some cases, so that the amount of spectral steepening becomes a diagnostic for source dynamical or geometrical properties.

description: We study the potential for controlled transfer of population to the biexciton state of a semiconductor quantum dot coupled with a metal nanoparticle, under the influence of an electromagnetic pulse with hyperbolic secant shape, and derive analytical solutions of the density matrix equations, for both zero and nonzero biexciton energy shift. These solutions lead to efficient transfer to the biexciton state, for various interparticle distances, including relatively small values. In certain cases, when the distance between the two particles is small, the transfer of population is strongly modified because of the influence of surface plasmons to the excitons, and the effect is more pronounced for shorter pulses. The hybrid snanostructure that we study has been proposed for generating efficiently polarization-entangled photons, thus the successful biexciton state preparation considered here is expected to contribute in this line of research.

description: We discuss reorganizing finite temperature perturbation theory using hard-thermal-loop (HTL) perturbation theory in order to improve the convergence of successive perturbative approximations to the free energy of a gauge theory. We briefly review the history of the technique and present new results for the three-loop HTL-improved approximation for the free energy of QED. We show that the hard-thermal-loop perturbation reorganization improves the convergence of the successive approximations to the QED free energy at intermediate coupling, e ~ 2. The reorganization is gauge invariant by construction, and due to cancellation among various contributions, one can obtain a completely analytic result for the resummed thermodynamic potential at three loops.

description: Some of the very high energy (VHE) gamma-ray sources detected with the modern generation of Cherenkov telescopes have been identified with previously known X-ray binary systems. These detections demonstrate the richness of non-thermal phenomena in compact galactic objects containing relativistic outflows or winds produced near black holes and neutron stars. Recently, the well-known microquasar Cygnus X-3 seems to be associated with a gamma-ray source detected with AGILE. Here I summarise the main observational results on gamma-ray emission from X-ray binaries, as well as some of the proposed scenarios to explain the production of VHE gamma-rays.

Noise-based logic hyperspace with the superposition of 2^N states in a single wire

description: In the introductory paper, [Physics Letters A 373 (2009) 911-918], arXiv:0808.3162, about noise-based logic, we showed how simple superpositions of single logic basis vectors can be achieved in a single wire. The superposition components were the N orthogonal logic basis vectors. Supposing that the different logic values have "on/off" states only, the resultant discrete superposition state represents a single number with N bit accuracy in a single wire, where N is the number of orthogonal logic vectors in the base. In the present paper, we show that the logic hyperspace (product) vectors defined in the introductory paper can be generalized to provide the discrete superposition of 2^N orthogonal system states. This is equivalent to a multi-valued logic system with 2^(2^N) logic values per wire. This is a similar situation to quantum informatics with N qubits, and hence we introduce the notion of noise-bit. This system has major differences compared to quantum informatics. The noise-based logic system is deterministic and each superposition element is instantly accessible with the high digital accuracy, via a real hardware parallelism, without decoherence and error correction, and without the requirement of repeating the logic operation many times to extract the probabilistic information. Moreover, the states in noise-based logic do not have to be normalized, and non-unitary operations can also be used. As an example, we introduce a string search algorithm which is O(M^0.5) times faster than Grover's quantum algorithm (where M is the number of string entries), while it has the same hardware complexity class as the quantum algorithm.

description: Einkommens- und Vermögensverteilung, Pareto-Verteilung, Allometrie. The discussion of the relations of income and wealth will now be extended to take account of influences in both directions. The starting point will be the regression of income on wealth which seems to be linear as far as our data go. This may be regarded as a case of allometry, in analogy to a "law" well known to biologists: Various parts of an organism grow at different but constant rates and as a result the proportions of their sizes (on log scale) remain constant in the growing body. Thus in our case the income is y=kw+yo, where we suppose that the distribution of income and wealth reflects a growth process which has taken place in the past. (Auszug, S.1)

description: The dwarf galaxy companions to the Milky Way are unique cosmological laboratories. With luminosities as low as 10^-7 L_MW, they inhabit the lowest mass dark matter halos known to host stars and are presently the most direct tracers of the distribution, mass spectrum, and clustering scale of dark matter. Their resolved stellar populations also facilitate detailed studies of their history and mass content. To fully exploit this potential requires a well-defined census of virtually invisible galaxies to the faintest possible limits and to the largest possible distances. I review the past and present impacts of survey astronomy on the census of Milky Way dwarf galaxy companions, and discuss the future of finding ultra-faint dwarf galaxies around the Milky Way and beyond in wide-field survey data.

description: Visual grounding (VG) aims to locate a specific target in an image based on a given language query. The discriminative information from context is important for distinguishing the target from other objects, particularly for the targets that have the same category as others. However, most previous methods underestimate such information. Moreover, they are usually designed for the standard scene (without any novel object), which limits their generalization to the open-vocabulary scene. In this paper, we propose a novel framework with context disentangling and prototype inheriting for robust visual grounding to handle both scenes. Specifically, the context disentangling disentangles the referent and context features, which achieves better discrimination between them. The prototype inheriting inherits the prototypes discovered from the disentangled visual features by a prototype bank to fully utilize the seen data, especially for the open-vocabulary scene. The fused features, obtained by leveraging Hadamard product on disentangled linguistic and visual features of prototypes to avoid sharp adjusting the importance between the two types of features, are then attached with a special token and feed to a vision Transformer encoder for bounding box regression. Extensive experiments are conducted on both standard and open-vocabulary scenes. The performance comparisons indicate that our method outperforms the state-of-the-art methods in both scenarios. {The code is available at https://github.com/WayneTomas/TransCP.

description: Corruption studies must evolve to match the complexity of the modern world. Here, we present three main problems in corruption analysis that need to be address: the complexity of the corruption phenomenon itself and its context, the complexity of the analytical description, and the complexity of the perspectives that different disciplines bring to the table. In this regard, we argue that the interdisciplinary framework of complex systems and network science represent a promising analytical approach to move forward in this endeavor. Furthermore, current research efforts in this direction indicate the dawn of a new interdisciplinary discipline for corruption studies in the 21st century.

description: A detailed morphological description and diagnosis of Tephritis are compiled, phylogenetically significant characters are selected. Phylogenetic analysis based on morphological ab biological characters, and also on nucleotide sequqnces of mtDNA СОІ has confirmed monophyly of Tephritis and its belonging in the monophyletic cluster Tephritis — Trupanea. Ten species groups are recognized; species in most of them are associated with asteraceous plants of certain tribes. Heringina spp. have no essential differences from Tephritis spp., forming an in-group of the genus Tephritis, and the name Heringina Aczél, 1940 is therefore to be synonymized with Tephritis Latreille, 1804. Among the Western Palaearctic species of Tephritis, monophagous (48), narrow olygophagous (29) and broad olygophagous (9) species dominate; the host plants for the rest are unknown. Larvae develop in the flower heads of asteraceous plants of the tribes Anthemideae (20%), Astereae (3%), Cardueae (30%), Cichorieae (26%), Inuleae (8%), Senecionеae (2%), and Calenduleae (1%). Host plants are recorded for the first time for 11 species of flies, and 16 plant species are recorded for the first time as host plants for flies of the genus Tephritis. Palaearctic species of the genus Tephritis are shown to overwinter as adults. Larvae occur exclusively during the warm season. Species of Tephritis inhabit flower buds of the asteraceous plants and usually finalize their preimaginal development before other tephritids, weevils, and moths. The genus Tephritis occurs almost exclusively in the Holarctics, with a few species, penetrating into the Oriental Region by the mountain ridges. Of the 152 known Tephritis species, 117 occur in the Palaearctic Region. The Mediterranean (Ancient Mediterranean) Region (in the sense of Kryzhanovsky, 2004) is by far the richest, with 80 species. Existence of the boreal-montane and European-Caucasian montane and forest areals shows that they were entire in the Pleistocene past. The chains of vicariate species in the mountain systems of the Sahara- Gobian Subregion indicate the main primary distribution and species diversity centre of Tephritis in Pliocene. The most complete key to 83 species occurring in the Western Palaearctics involves also little-known and new key characters (as wing cell and aculeus size, genitalic morphology, etc.).

We use this setup to explain late-time accelerated expansion and crossing of the phantom divide line by the equation of state parameter of this non-minimally coupled dark energy component. By analyzing parameter space of the model, we show that this model accounts for accelerated expansion and crossing of the phantom divide line with a suitable fine-tuning of the nonminimal coupling. Then we study the issue of bouncing solutions in this framework.

description: Recent research has identified discriminatory behavior of automated prediction algorithms towards groups identified on specific protected attributes (e.g., gender, ethnicity, age group, etc.). When deployed in real-world scenarios, such techniques may demonstrate biased predictions resulting in unfair outcomes. Recent literature has witnessed algorithms for mitigating such biased behavior mostly by adding convex surrogates of fairness metrics such as demographic parity or equalized odds in the loss function, which are often not easy to estimate. This research proposes a novel in-processing based GroupMixNorm layer for mitigating bias from deep learning models. The GroupMixNorm layer probabilistically mixes group-level feature statistics of samples across different groups based on the protected attribute. The proposed method improves upon several fairness metrics with minimal impact on overall accuracy. Analysis on benchmark tabular and image datasets demonstrates the efficacy of the proposed method in achieving state-of-the-art performance. Further, the experimental analysis also suggests the robustness of the GroupMixNorm layer against new protected attributes during inference and its utility in eliminating bias from a pre-trained network.

description: Nonlocality lies at the core of quantum mechanics from both a fundamental and applicative point of view. It is typically revealed by a Bell test, that is by violation of a Bell inequality, whose success depends both on the state of the system and on parameters linked to experimental settings. This leads to find, given the state, optimized parameters for a successful test. Here we provide, for a quite general class of quantum states, the explicit expressions of these optimized parameters and point out that, for a continuous change of the state, the corresponding suitable experimental settings may unexpectedly vary discontinuously. We finally show in a paradigmatic open quantum system that this abrupt "jump" of the experimental settings may even occur during the time evolution of the system. These jumps must be taken into account in order not to compromise the correct detection of nonlocality in the system.

description: We present a theoretical study of time-dependent quantum transport in a resonant tunnel junction coupled to a nanomechanical oscillator within the non-equilibrium Green's function technique. An arbitrary voltage is applied to the tunnel junction and electrons in the leads are considered to be at zero temperature. The transient and the steady state behavior of the system is considered here in order to explore the quantum dynamics of the oscillator as a function of time. The properties of the phonon distribution of the nanomechnical oscillator strongly coupled to the electrons on the dot are investigated using a non-perturbative approach. We consider both the energy transferred from the electrons to the oscillator and the Fano factor as a function of time. We discuss the quantum dynamics of the nanomechanical oscillator in terms of pure and mixed states. We have found a significant difference between a quantum and a classical oscillator. In particular, the energy of a classical oscillator will always be dissipated by the electrons whereas the quantum oscillator remains in an excited state. This will provide useful insight for the design of experiments aimed at studying the quantum behavior of an oscillator.

description: In the lenticular galaxy NGC1023 a third population of globular clusters (GCs), called faint fuzzies (FFs), was discovered next to the blue and red GC populations by Larsen & Brodie. While these FFs have colors comparable to the red population, the new population is fainter, larger (R_eff > 7 pc) and, most importantly, shows clear signs of co-rotation with the galactic disk of NGC1023. We present N-body simulations verifying the hypothesis that these disk-associated FFs are related to the young massive cluster complexes (CCs) observed by Bastian et. al in M51, who discovered a mass-radius relation for these CCs. Our models have an initial configuration based on the observations from M51 and are placed on various orbits in a galactic potential derived for NGC1023. All computations end up with a stable object containing 10 to 60% of the initial CC mass after an integration time of 5 Gyr. A conversion to visual magnitudes demonstrates that the resulting objects cover exactly the observed range for FFs. Moreover, the simulated objects show projected half-mass radii between 3.6 and 13.4 pc, in good agreement with the observed FF sizes. We conclude that objects like the young massive CCs in M51 are likely progenitors of the FFs observed in NGC1023.

Despite these stringent quality control checks, individual bulls that pass the quality control checks can still vary in field fertility by up to 25%. A genome-wide association study was undertaken to determine genetic markers associated with prefreeze and post-thaw bull sperm quality traits as well as field fertility. Genome-wide association analysis was performed using a single nucleotide polymorphism (SNP) regression mixed linear model in WOMBAT. Genes within a 250 Kb span of a suggestive (P ≤ 1 × 10−5) SNP were considered as candidate genes. One SNP was associated with adjusted pregnancy rate, and 21 SNPs were associated across the seven semen quality traits (P ≤ 1 × 10−5). Functional candidate genes include SIPA1L2 which was associated with adjusted pregnancy rate. This encodes a Rap GTPase-activating protein involved in Rap1 signalling pathway and was previously found to play a role in the process of sperm differentiation. Gene ontology (GO) analysis also identified significantly enriched biological processes involved protein tyrosine kinase activity including genes such as DYRK1A, TEC and TXK that were associated with sperm motility prior to freezing. Another candidate gene associated with post-thaw sperm motility was FHDC1 which coordinates actin filament and microtubule dynamics. The induced 11 GO terms in the ejaculates rejected after freezing trait were related to ATPase, phosphatase and hydrolase activity. These results reveal novel specific genomic regions and candidate genes associated with economically important phenotypes such as field fertility and semen quality traits.

description: Pair creation in a uniform classical electromagnetic field (Schwinger mechanism) is studied focusing on the time evolution of the distribution of created particles. The time evolution of the distribution in time-dependent fields is also presented as well as effects of back reaction. Motivated by the Glasma flux tube, which may be formed at the initial stage of heavy-ion collisions, we investigate effects of a magnetic field parallel to an electric field, and find that the magnetic field makes the evolution of a fermion system faster.

description: Determining if the brain is developing normally is a key component of pediatric neuroradiology and neurology. Brain magnetic resonance imaging (MRI) of infants demonstrates a specific pattern of development beyond simply myelination. While radiologists have used myelination patterns, brain morphology and size characteristics to determine age-adequate brain maturity, this requires years of experience in pediatric neuroradiology. With no standardized criteria, visual estimation of the structural maturity of the brain from MRI before three years of age remains dominated by inter-observer and intra-observer variability. A more objective estimation of brain developmental age could help physicians identify many neurodevelopmental conditions and diseases earlier and more reliably. Such data, however, is naturally hard to obtain, and the observer ground truth not much of a gold standard due to subjectivity of assessment. In this light, we explore the general feasibility to tackle this task, and the utility of different approaches, including two- and three-dimensional convolutional neural networks (CNN) that were trained on a fusion of T1-weighted, T2-weighted, and proton density (PD) weighted sequences from 84 individual subjects divided into four age groups from birth to 3 years of age. In the best performing approach, we achieved an accuracy of 0.90 [95% CI:0.86-0.94] using a 2D CNN on a central axial thick slab. We discuss the comparison to 3D networks and show how the performance compares to the use of only one sequence (T1w). In conclusion, despite the theoretical superiority of 3D CNN approaches, in limited-data situations, such approaches are inferior to simpler architectures.

description: The increasing diffusion of wireless-enabled portable devices is pushing toward the design of novel service scenarios, promoting temporary and opportunistic interactions in infrastructure-less environments. Mobile Ad Hoc Networks (MANET) are the general model of these higly dynamic networks that can be specialized, depending on application cases, in more specific and refined models such as Vehicular Ad Hoc Networks and Wireless Sensor Networks. Two interesting deployment cases are of increasing relevance: resource diffusion among users equipped with portable devices, such as laptops, smart phones or PDAs in crowded areas (termed dense MANET) and dissemination/indexing of monitoring information collected in Vehicular Sensor Networks. The extreme dynamicity of these scenarios calls for novel distributed protocols and services facilitating application development. To this aim we have designed middleware solutions supporting these
challenging tasks. REDMAN manages, retrieves, and disseminates replicas of software resources in dense MANET; it implements novel lightweight protocols to maintain a desired replication degree despite participants mobility, and efficiently perform resource retrieval. REDMAN exploits the high-density assumption to achieve scalability and limited network overhead. Sensed data gathering and distributed indexing in Vehicular Networks raise similar
issues: we propose a specific middleware support, called MobEyes, exploiting node mobility to opportunistically diffuse data summaries among neighbor vehicles. MobEyes
creates a low-cost opportunistic distributed index to query the distributed storage and to determine the location of needed information. Extensive validation and testing of REDMAN and MobEyes prove the effectiveness of our original solutions in limiting communication overhead while maintaining the required accuracy of replication degree and indexing completeness, and demonstrates the feasibility of the middleware approach.

description: We introduce a new physical parameter, the optical variability amplitude, to the well-established Eigenvector 1 space of quasars and test a sample of long-term B-band light curves of 42 PG quasars monitored by Giveon et al. (1999). We find that the optical variability amplitude strongly correlates with the intensity ratio of Fe II to H$β$, H$β$ width and peak luminosity at 5007$\rmÅ$. We briefly discuss the physical meaning of our findings and suggest that the Eddington ratio may be a key factor in determining a quasar's variability.

description: Excited-state quantum phase transitions (ESQPTs) are critical phenomena that generate singularities in the spectrum of quantum systems. {For systems with a classical counterpart,} these phenomena have their origin in the classical limit when the separatrix of an unstable periodic orbit divides phase space into different regions. Using a semiclassical theory of wave propagation based on the manifolds of unstable periodic orbits, we describe the quantum states associated with an ESQPT {for the quantum standard map: a paradigmatic example of a kicked quantum system}. {Moreover, we show that finite-size precursors of ESQPTs shrink as chaos increases due to the disturbance of the system. This phenomenon is explained through destructive interference between principal homoclinic orbits}

description: Periodic nonuniform sampling is a known method to sample spectrally sparse signals below the Nyquist rate. This strategy relies on the implicit assumption that the individual samplers are exposed to the entire frequency range. This assumption becomes impractical for wideband sparse signals. The current paper proposes an alternative sampling stage that does not require a full-band front end. Instead, signals are captured with an analog front end that consists of a bank of multipliers and lowpass filters whose cutoff is much lower than the Nyquist rate. The problem of recovering the original signal from the low-rate samples can be studied within the framework of compressive sampling. An appropriate parameter selection ensures that the samples uniquely determine the analog input. Moreover, the analog input can be stably reconstructed with digital algorithms. Numerical experiments support the theoretical analysis.

description: Probabilistic omega-automata are variants of nondeterministic automata for infinite words where all choices are resolved by probabilistic distributions. Acceptance of an infinite input word can be defined in different ways: by requiring that (i) the probability for the accepting runs is positive (probable semantics), or (ii) almost all runs are accepting (almost-sure semantics), or (iii) the probability measure of the accepting runs is greater than a certain threshold (threshold semantics). The underlying notion of an accepting run can be defined as for standard omega-automata by means of a Buechi condition or other acceptance conditions, e.g., Rabin or Streett conditions. In this paper, we put the main focus on the probable semantics and provide a summary of the fundamental properties of probabilistic omega-automata concerning expressiveness, efficiency, and decision problems.

Projection of population and industrial employment in the Vancouver C.M.A.
Creators: name: Skene, Patricia Aileen Thelma
Publisher: name: University of British Columbia
Year: 2010

description: The goal of this thesis is to draw together the principal factors affecting regional growth and to apply this knowledge to the Vancouver C.M.A. This involves three objectives. The first objective is to review the literature pertaining to the theory of regional growth. This review appears in Chapters 1, 2, and 4. These chapters constitute an attempt to draw together important factors from an extremely wide field. This work is designed to provide a framework for evaluation of the state of the art in regional projection models. The second objective is to review the literature to find examples of practical applications of the above theory. Specific examples of population and economic models for projection are examined and their major features are presented in Chapters 3 and 5. A model based on the state of the art is created and reported in Chapter 6. This work involves the use of available regional sectoral employment data and a shift-share model to produce employment projections. These employment projections are then combined with an estimate of the historical relationship between migration and employment in the region to produce an estimate of projected migration. The projected migration is an input to the cohort survival model which projects future population. A check on the consistency of the estimates of population and employment is provided by the calculation of the expected employment rate. In conclusion, the literature review reveals the complexity of the phenomenon of regional growth. It also reveals that large scale computer models have not been highly successful in dealing with the problem. This leads to the conclusion that simple models are more desirable for projection purposes. However, in the present case, the simplicity of the shift-share model is perhaps too great. The model, in general, explains less of past growth than does a simple time trend extrapolation model. The population model, while also simple in structure, performs much better. In that case the major factors affecting population growth (fertility, mortality and migration) are treated separately in the model. It would be desirable to explain the separate components of regional economic growth (labour, capital, technical knowledge). The major limiting factor to this task is the quantity and quality of regional data available. Until this is improved, regional analysts will be confined to unsatisfactory projection models.
