description: We examine the recovery of block sparse signals and extend the framework in two important directions; one by exploiting signals' intra-block correlation and the other by generalizing signals' block structure. We propose two families of algorithms based on the framework of block sparse Bayesian learning (BSBL). One family, directly derived from the BSBL framework, requires knowledge of the block structure. Another family, derived from an expanded BSBL framework, is based on a weaker assumption on the block structure, and can be used when the block structure is completely unknown. Using these algorithms we show that exploiting intra-block correlation is very helpful in improving recovery performance. These algorithms also shed light on how to modify existing algorithms or design new ones to exploit such correlation and improve performance.

description: Considering a nonperishable product which may be stored either in an own warehouse or in both the own and the rented warehouse, this paper deals with the ordering decisions under a generalized trapezoidal-type demand rate in an inventory system. Shortages are allowed and the unsatisfied demand is assumed to be partially backlogged. Furthermore, the existence and uniqueness of the optimal solution to each warehouse mode is proved and used in an easy-to-use algorithm, and a decision-making theorem for measuring whether to adopt a rented warehouse is developed. Finally, numerical examples and a case study are presented to illustrate the feasibility and efficiency of the proposed model and algorithm. The results show that, the storage capacity of the own warehouse and the unit rental cost have remarkable impact on determining whether to use the rented warehouse. When both the unit rental cost and the unit opportunity cost are higher in the external market, the profitability of the inventory system mainly relies on the storage capacity of the own warehouse. Meanwhile, the optimal profit performance is sensitive to the selling price and the purchasing cost, and the optimal rented warehouse’s ordering quantity is sensitive to the order cycle length. But overall, the proposed model is basically robust.
Generalized Error Exponents For Small Sample Universal Hypothesis Testing

description: The small sample universal hypothesis testing problem is investigated in this paper, in which the number of samples $n$ is smaller than the number of possible outcomes $m$. The goal of this work is to find an appropriate criterion to analyze statistical tests in this setting. A suitable model for analysis is the high-dimensional model in which both $n$ and $m$ increase to infinity, and $n=o(m)$. A new performance criterion based on large deviations analysis is proposed and it generalizes the classical error exponent applicable for large sample problems (in which $m=O(n)$). This generalized error exponent criterion provides insights that are not available from asymptotic consistency or central limit theorem analysis. The following results are established for the uniform null distribution: (i) The best achievable probability of error $P_e$ decays as $P_e=\exp\{-(n^2/m) J (1+o(1))\}$ for some $J>0$. (ii) A class of tests based on separable statistics, including the coincidence-based test, attains the optimal generalized error exponents. (iii) Pearson's chi-square test has a zero generalized error exponent and thus its probability of error is asymptotically larger than the optimal test.

Anomalous U(1) Mediation in Large Volume Compactification

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study the general effects of anomalous U(1)_A gauge symmetry on soft supersymmetry (SUSY) breaking terms in large volume scenario, where the MSSM sector is localized on a small cycle whose volume is stabilized by the D-term potential of the U(1)_A. Since it obtains SUSY breaking mass regardless of the detailed form of Kähler potential, the U(1)_A vector superfield acts as a messenger mediating the SUSY breaking in the moduli sector to the MSSM sector. Then, through the loops of U(1)_A vector superfield, there arise soft masses of the order of m_{3/2}^2/8π^2 for scalar mass squares, m_{3/2}/(8π^2)^2 for gaugino masses, and m_{3/2}/8π^2 for A-paramteres. In addition, the massive U(1)_A vector superfield can have non-zero F and D-components through the moduli mixing in the Kähler potential, and this can result in larger soft masses depending upon the details of the moduli mixing. For instance, in the presence of one-loop induced moduli mixing between the visible sector modulus and the large volume modulus, the U(1)_A D-term provides soft scalar mass squares of the order of m_{3/2}^2. However, if the visible sector modulus is mixed only with small cycle moduli, its effect on soft terms depends on how to stabilize the small cycle moduli.

description: We consider theories where the dark matter particle carries flavor quantum numbers, and has renormalizable contact interactions with the Standard Model fields. The phenomenology of this scenario depends sensitively on whether dark matter carries lepton flavor, quark flavor or its own internal flavor quantum numbers. We show that each of these possibilities is associated with a characteristic type of vertex, has different implications for direct detection experiments and gives rise to distinct collider signatures. We find that the region of parameter space where dark matter has the right abundance to be a thermal relic is in general within reach of current direct detection experiments. We focus on a class of models where dark matter carries tau flavor, and show that the collider signals of these models include events with four or more isolated leptons and missing energy. A full simulation of the signal and backgrounds, including detector effects, shows that in a significant part of parameter space these theories can be discovered above Standard Model backgrounds at the Large Hadron Collider. We also study the extent to which flavor and charge correlations among the final state leptons allows models of this type to be distinguished from theories where dark matter couples to leptons but does not carry flavor.

description: We apply a recently developed functional renormalization group (fRG) scheme for quantum spin systems to the spin-1/2 antiferromagnetic XXZ model on a two-dimensional square lattice. Based on an auxiliary fermion representation we derive flow equations which allow a resummation of the perturbation series in the spin-spin interactions. Spin susceptibilities are calculated for different values of the anisotropy parameter. The phase transition between planar and axial ordering at the isotropic point is reproduced correctly. The results for the critical scales from the fRG as quantitative measures for the ordering temperatures are in good agreement with the exact solution in the Ising limit. On the easy-plane side, the deviations from critical temperatures obtained with quantum Monte Carlo are larger but still acceptable. However, at the isotropic point the Mermin-Wagner theorem is violated such that a precise description of the behavior in the vicinity of the phase transition is not possible. We discuss possible reasons for these discrepanies.

Impact of eV-mass sterile neutrinos on neutrino-driven supernova outflows

description: Motivated by recent hints for sterile neutrinos from the reactor anomaly, we study active-sterile conversions in a three-flavor scenario (2 active + 1 sterile families) for three different representative times during the neutrino-cooling evolution of the proto-neutron star born in an electron-capture supernova. In our "early model" (0.5 s post bounce), the nu_e-nu_s MSW effect driven by Delta m^2=2.35 eV^2 is dominated by ordinary matter and leads to a complete nu_e-nu_s swap with little or no trace of collective flavor oscillations. In our "intermediate" (2.9 s p.b.) and "late models" (6.5 s p.b.), neutrinos themselves significantly modify the nu_e-nu_s matter effect, and, in particular in the late model, nu-nu refraction strongly reduces the matter effect, largely suppressing the overall nu_e-nu_s MSW conversion. This phenomenon has not been reported in previous studies of active-sterile supernova neutrino oscillations. We always include the feedback effect on the electron fraction Y_e due to neutrino oscillations. In all examples, Y_e is reduced and therefore the presence of sterile neutrinos can affect the conditions for heavy-element formation in the supernova ejecta, even if probably not enabling the r-process in the investigated outflows of an electron-capture supernova. The impact of neutrino-neutrino refraction is strong but complicated, leaving open the possibility that with a more complete treatment, or for other supernova models, active-sterile neutrino oscillations could generate conditions suitable for the r-process.

Exploring the cohabitation effect : untangling the life course diversity of cohabiting unions
Creators: name: Martin, Todd Forrest
Publisher: name: University of British Columbia
Year: 2013

description: The cohabitation effect has been identified as a factor in former cohabitors’ increased marital instability. Current research on this effect is mixed. Recent data indicates that the cohabitation effect has not only diminished in current cohorts but has now reversed. These findings indicate former cohabitors now have enhanced odds of marital stability. In order to examine the changing dynamics of cohabitation and its effect on later marital stability, this research utilizes cross tabulations, optimal matching analysis and logistic regression to study The British Household Panel Survey, a nationally representative panel data set. First unions that went straight to marriage were compared to first unions that were cohabiting unions but later transformed to marriages. Life course theory and diffusion theory are used to provide the framework for testing whether a cohabitation effects exists, how it may have changed over time, and how predictive variables are changing. The social and historical context of cohabitation is established by looking at the recent histories of marriage, divorce and cohabitation. Cohabitation typologies are presented as well as alternative explanations for the cohabitation effect such as institutionalism, sliding verse deciding, diffusion, sequencing and age and period and cohort effects. The data shows a clearly established cohort effect at the turn of the twentieth century. This effect remained stable until the post WWII period where it began to diminish, paralleling the rise in the adoption and social acceptance of pre-marital cohabitation. As cohabitation became more normative, the effect becomes less discernible. Logistic regression highlighted five main variables of importance across pathways and time: age at first union, diffusion, education, religious and traditional family values. The implication of how these variables changed is discussed in the context of a proposal to move from an emphasis on the cohabitation effect to an emphasis on the effect of each of these variables on union pathway selection and later marital stability.

description: Discrete-time discrete-state random Markov chains with a tridiagonal generator are shown to have a random attractor consisting of singleton subsets, essentially a random path, in the simplex of probability vectors. The proof uses the Hilbert projection metric and the fact that the linear cocycle generated by the Markov chain is a uniformly contractive mapping of the positive cone into itself. The proof does not involve probabilistic properties of the sample path and is thus equally valid in the nonautonomous deterministic context of Markov chains with, say, periodically varying transitions probabilities, in which case the attractor is a periodic path.

description: We study in this paper bond distortion effect on electric polarization in spiral multiferroic magnets based on cluster and chain models. The bond distortion break inversion symmetry and modify the $d$-$p$ hybridization. Consequently, it will affect electric polarization which can be divided into spin-current part and lattice-mediated part. The spin-current polarization can be written in terms of $\vec{e}_{i,j}\times(\vec{e}_{i}\times\vec{e}_{j}) $ and the lattice-mediated polarization exists only when the M-O-M bond is distorted. The electric polarization for three-atom M-O-M and four-atom M-O$_{2}$-M clusters is calculated. We also study possible electric ordering in three kinds of chains made of different clusters. We apply our theory to multiferroics cuprates and find that the results are in agreement with experimental observations.

description: We investigate the structure of halos in the sDGP (self-accelerating branch of the Dvali-Gavadadze-Porrati braneworld gravity) model and the galileon modified gravity model on the basis of the static and spherically symmetric solutions of the collisionless Boltzmann equation, which reduce to the singular isothermal sphere model and the King model in the limit of Newtonian gravity. The common feature of these halos is that the density of a halo in the outer region is larger (smaller) in the sDGP (galileon) model, respectively, in comparison with Newtonian gravity. This comes from the suppression (enhancement) of the effective gravity at large distance in the sDGP (galileon) model, respectively. However, the difference between these modified gravity models and Newtonian gravity only appears outside the halo due to the Vainshtein mechanism, which makes it difficult to distinguish between them. We also discuss the case in which the halo density profile is fixed independently of the gravity model for comparison between our results and previous work.

Il teatro come forma che pensa. Pregiudizio antiteatrale, materialità e abiezione nella scena postdrammatica
Creators: name: Sacchi, Annalisa
Publisher: name: Università degli Studi di Milano
Year: 2013

description: If one turns to the source of the so-called antitheatrical prejudice, Plato, and explores beside his notorious critics to the arts also his statements about the spectatorship, something intriguing appears. It appears that common origins link the theoretical meditation and the theatrical specta-torship, encapsulating these two occupations in the Greek word theoria, in which the sense of sight is crucial to both the act of going to the thea-tre and of engaging in theoretical inquiry. This mutual and ambivalent attraction of theatre toward philosophy and of philosophy toward theatre reaches a sort of climax in the era of post-dramatic theatre. Dismissed the general aversion to “theatricality” – still at stake within the Modern-ism theatre – contemporary theatrical scene has been demonstrating to what extent theatre is in itself a “thinking form”, or a form of thinking embodied in the material presence of the performer. Far from causing the sort of embarrassment and frustration denounced by modernist theatre artists such as Edward Gordon Craig, the actor’s deliberate vulnerability possibly enables our own and prompts us toward empathy and theoreti-cal understanding. Watching live performance is watching the actor dy-ing onstage; sharing that liveness promotes a necessary and moving con-frontation with mortality.

Il collasso del dramma: cosa rimane?
Creators: name: De Carvalho Carneiro, Ana Candida

Year: 2013

description: The Neo-avantgardes of the 20th century left an indelible mark on the idea of theatre, establishing once and for all the concept of drama as a theatrical form, historically defined and based on identifiable criteria. The script as an end in itself was either dismissed – and pure performance was thus preferred –, or it was used as a device or starting point for what was occurring on stage in the hybrid, experimental theatrical forms. The role of playwrights – and therefore that of the script as an independently meaningful structure – fell into a deep crisis. By coming to grips with the new experiences, playwrights were able to explore new modes of textual expression, putting their art back on the right track. What dimensions do the categories of drama take on today? What are the new literary devices and techniques that contemporary playwrights can adopt? In order to try and answer these questions, we will analyse the script La demande d’emploi (The job application) by Michel Vinaver. Although written in 1971 – therefore, at the very beginning of the mentioned revolutionary period –, it already presents very important features of a type of playwriting that can be qualified as post-dramatic, like almost the entirety of the playwright’s work. We will explore and develop concepts like fragment, movement and polyphony, that can be frequently encountered in contemporary theatrical texts and with which both scholars and theatre professionals have to come to terms.

description: Machine learning has become a very important aspect of the development of artificial intelligence (AI) in the world of computing. As a part of the machine learning techniques, reinforcement learning enables an agent to explore and study the unknown environment and through trial and error, the agent learns how to perform desired tasks in an optimum way. In this project, one of the methods to solve reinforcement problems, namely Q-learning, is studied and analysed. A maze problem is set up to count the learning time of an agent to travel from a fixed starting point A to destination B using Q-learning algorithm on Matlab platform. The learning time will be studied and then compared with different sets of maze of different size and complexity. Finally, a thorough discussion on the differences in the learning time and methods to further optimise the Q-learning algorithm will be provided. This document reports the outcome of this project and highlights the problems and challenges encountered and solutions devised.

description: This article provides an introduction to on-shell recursion relations for calculations of tree-level amplitudes. Starting with the basics, such as spinor notations and color decompositions, we expose analytic properties of gauge-boson amplitudes, BCFW-deformations, the large $z$-behavior of amplitudes, and on-shell recursion relations of gluons. We discuss further developments of on-shell recursion relations, including generalization to other quantum field theories, supersymmetric theories in particular, recursion relations for off-shell currents, recursion relation with nonzero boundary contributions, bonus relations, relations for rational parts of one-loop amplitudes, recursion relations in 3D and a proof of CSW rules. Finally, we present samples of applications, including solutions of split helicity amplitudes and of N= 4 SYM theories, consequences of consistent conditions under recursion relation, Kleiss-Kuijf (KK) and Bern-Carrasco-Johansson (BCJ) relations for color-ordered gluon tree amplitudes, Kawai-Lewellen-Tye (KLT) relations.

Esperienza estetica e unità di coscienza

description: Jung considers the symbol as a unifying and transcendent element, as an image capable of unifying the various aspects of consciousness (sensation, intuition, feeling and thought) in a gradual rapprochement to the essential unity of being. However, this point is controversial,  since the symbol is the expression of a sense that while not entirely rational, concern the cognitive sphere. Therefore what Jung attributes to the symbol (its unifying and transcendent power) was transferred to the aesthetic experience of art, where the same aspects of consciousness in the symbol are supported by perceptual elements, according to a level of completeness and unity that only the aesthetic experience of art can achieve.

Da Saramago a Cechov: il teatro musicale di Azio Corghi e il “teatro epico” del ‘900
Creators: name: Seminara, Graziella
Publisher: name: Università degli Studi di Milano
Year: 2013

description: Since his debut, in Gargantua (1984, by François Rabelais), and even more in the works composed in collaboration with José Saramago (Blimunda, 1990; Divara, 1993), Azio Corghi has pursued an idea of drama characterized by a marked ‘aesthetic presence’ of the author and by his vision of the world, typical of the ‘epic’ theatre of the twentieth century. In 2000, composing Tat’jana Repina (2000) by Chekhov, with his ‘open’ theatricality and tormented existential problems, the musician was forced to rethink his musical dramaturgy: the landscapes of History designed by Saramago are replaced by a psychological story, which takes place in a ‘community’ of individuals marked by loneliness and despair; and the choral, ‘collective’ dimension, which in Blimunda and Divara arose from History, is converted into a ‘monological’ chorus which is typically Chekhovian and shows the crisis of communication typical of the modern theatre. To convey the bleak pessimism of Chekhov, in Tat’jana – going beyond Blimunda and Divara’s predominant symbolism – Corghi pushed his writing to the highest level of abstraction, used only at the beginning, during his structuralist period, no more in accordance with the strict determinism of post-Webern avant-garde but according to a free choice, dictated by inner artistic necessity.

description: Η μυκηναϊκή ακρόπολη της Εφύρας στο παράκτιο πέρασμα του Ιονίου πελάγους αποτελεί ίσως τη σημαντικότερη θέση της Υστεροελλαδικής ΙΙΙ περιόδου στην Ήπειρο, ως εμπορικός σταθμός στον κάμπο του Φαναρίου και τις εκβολές του ποταμού Αχέροντα με διαθέσιμη ευλίμενη εγκατάσταση. Ο υπό συζήτηση νέος μυκηναϊκός λακκοειδής τάφος ανακαλύφθηκε τυχαία το έτος 2012 εκτός των τειχών της μυκηναϊκής ακρόπολης της Εφύρας στις εργασίες ανάδειξης των αρχαιολογικών χώρων Νεκρομαντείου και Εφύρας. Ο ανδρικός σκελετός βρέθηκε πλούσια κτερισμένος με χάλκινα όπλα (ένα εγχειρίδιο με λαβή Τ, μια φυλλόσχημη και δύο φλογόσχημες αιχμές δοράτων) και εργαλεία (ένα μονόστομο μαχαίρι, μια επίπεδη σμίλη και μια κωνική σμίλη), λίγα αντικείμενα προσωπικού καλλωπισμού (τρεις οστέινες περόνες και μια χρυσή ψήφος), καθώς και με εννιά μυκηναϊκά αγγεία. Ο νέος τάφος εντοπίστηκε εκτός των τειχών σε επαφή με το οχυρωματικό τείχος και σε μικρή απόσταση από την κύρια νότια πύλη της μυκηναϊκής ακρόπολης. Εξαιτίας της θέσης εύρεσης και του πλούτου ή ποικιλίας των κτερισμάτων διακρίνεται σημαντικά από τους γνωστούς τάφους των τριών ταφικών τύμβων στο εσωτερικό της μυκηναϊκής ακρόπολης, αλλά και όλης της Ηπείρου. Ο προικισμένος με την αρετή της ανδρείας τοπικός «ήρωας της Εφύρας» τιμήθηκε από τους πολίτες της ακμάζουσας μυκηναϊκής κοινότητας σε μια μεταβατική εποχή με πολλές αντιξοότητες.

La pratica attoriale in Richard Schechner: dalla sensazione all’essere. Sulle tracce della fenomenologia di Merleau-Ponty
Creators: name: Giraldo, Mabel
Publisher: name: Università degli Studi di Milano
Year: 2013

description: Against Cartesian dualism and in line with the general twentieth-century rediscovery of body and perception, this paper aims to examine the role of senses for the performer, as presented by Richard Schechner’s theory of performance. Such a theory finds its legitimacy in the pages of the philosopher Mearleu-Ponty, and in the priority the philosopher assigned to perception and senses as sources of knowledge, as well as opening of consciousness to the world.

Topological Susceptibility and Contact Term in QCD. A Toy Model

description: We study a number of different ingredients related to $θ$ dependence, the non-dispersive contribution in topological susceptibility with the "wrong" sign, topological sectors in gauge theories, and related subjects using a simple "deformed QCD". This model is a weakly coupled gauge theory, which however has all the relevant essential elements allowing us to study difficult and nontrivial questions which are known to be present in real strongly coupled QCD. Essentially we want to test the ideas related to the $U(1)_A$ problem in a theoretically controllable manner using the "deformed QCD" as a toy model. One can explicitly see microscopically how the crucial elements work.

description: In this paper, we report the results of constraining the dynamical dark energy with a divergence-free parameterization, $w(z) = w_{0} + w_{a}(\frac{\ln(2+z)}{1+z}-\ln2)$, in the presence of spatial curvature and massive neutrinos, with the 7-yr WMAP temperature and polarization data, the power spectrum of LRGs derived from SDSS DR7, the Type Ia supernova data from Union2 sample, and the new measurements of $H_0$ from HST, by using a MCMC global fit method. Our focus is on the determinations of the spatial curvature, $Ω_k$, and the total mass of neutrinos, $\sum m_ν$, in such a dynamical dark energy scenario, and the influence of these factors to the constraints on the dark energy parameters, $w_0$ and $w_a$. We show that $Ω_k$ and $\sum m_ν$ can be well constrained in this model; the 95% CL limits are: $-0.0153

Microarthropod diversity and distribution in Southwestern Canada
Creators: name: Chen, Youhua
Publisher: name: University of British Columbia
Year: 2013

description: Microarthropod diversity patterns were investigated in southwestern British Columbia, Canada. We surveyed soil microarthropods associated with moss carpets on exposed rocky outcrops. Our survey identified 352 morphospecies in 32 sites spanning a 130 km 60 km area. Previous studies have interpreted strong correlations of species composition with environmental factors as evidence of niche limitation, and strong correlations with spatial factors as evidence of dispersal limitation. Here, we examine 18 ecological variables relevant to either spatial location or environmental aspects of ecological processes, and evaluate their influences on the microarthropod community. We tested whether the relative importance of spatial and environmental factors was concordant between various community attributes including composition, abundance and species richness, and between different taxonomic groups of microarthropods (Oribatida, Mesostigmata, Collembola). We used two different methods (distance-based Mantel and raw data-based ordination methods) to show that spatial variables could not explain composition or compositional turnover for most microarthropod groups, except Collembola. Dispersal limitation of Collembola is surprising given the high dispersal ability of this group. Although environmental factors explained a large amount of spatial variance in composition (raw data-based ordination method) for all microarthropod groups, environmental similarity (distance-based Mantel method) was a poor predictor of compositional similarity for Oribatida and Mesostigmata. Total abundance and species richness could also be explained by combinations of environmental factors, particularly those relating to tree cover and soil-relevant microhabitat variables (i.e, water content/mass, total soil mass and particle mass), but total abundance and richness were themselves only weakly correlated across space. The most important environmental influences on microarthropod communities were tree cover and water mass, followed by distance-to-sea. At the same time, there was a lot of unexplained variance in the composition of microarthropod communities (especially for species incidences) which could not be explained by the available ecological variables. As richness hotspots were dispersed across different habitats for different taxonomic groups, we suggested that species interactions might be equally important as environmental filtering and spatial autocorrelation in shaping microarthropod community structure, especially for patterns in species incidence.
Constraints on the interpretation of the superluminal motion of neutrinos at OPERA

description: Various approaches aim to describe the recent analysis by the OPERA experiment, which indicates that neutrinos travel faster than the speed of light. We demonstrate that any such theoretical or experimental explanation must not destroy the complicated (nonlinear) structure of the proton waveform recovered in the neutrino signal. As one example, consider that only a fraction of the neutrinos travel faster than the speed of light, such as sterile neutrinos. We fit the OPERA data including this fraction as a free variable, assuming that the OPERA result is correct. In our analysis, the best-fit values are 50% of the neutrinos being superluminal and (v-c)/c = 4.5 10^{-5}, where the neutrino velocity increases as the fraction of superluminal neutrinos decreases. The minimal fraction of superluminal neutrinos is found to be 17% (3 sigma), which is constrained by the non-linearity of the proton waveform. This minimal fraction challenges the hypothesis that only sterile neutrinos travel faster than the speed of light. In addition, we demonstrate that an experimental effect introducing a smearing between the proton waveform and neutrino signal, as expected for some systematical errors, is also limited by the shape of the waveform. Finally, we illustrate that even stronger constraints may be obtained from the recent analysis with a short-bunch beam, in spite of the low statistics.
