description: We describe the structural relations between nested harmonic sums emerging in the description of physical single scale quantities up to the 3--loop level in renormalizable gauge field theories. These are weight {\sf w=6} harmonic sums. We identify universal basic functions which allow to describe a large class of physical quantities and derive their complex analysis. For the 3--loop QCD Wilson coefficients 35 basic functions are required, whereas a subset of 15 describes the 3--loop anomalous dimensions.

description: We provide the first comprehensive study of hyperons in neutron star mergers and quantify their specific impact. We discuss the thermal behavior of hyperonic equations of state~(EoSs) as a distinguishing feature from purely nucleonic models in the remnants of binary mergers using a large set of numerical simulations. Finite temperature enhances the production of hyperons, which leads to a reduced pressure as highly degenerate nucleons are depopulated. This results in a characteristic increase of the dominant postmerger gravitational-wave frequency by up to $\sim150$~Hz compared to purely nucleonic EoS models. By our comparative approach we can directly link this effect to the occurrence of hyperons. Although this feature is generally weak, it is in principle measurable if the EoS and stellar parameters of cold neutron stars are sufficiently well determined. Considering that the mass-radius relations of purely nucleonic and hyperonic EoSs may be indistinguishable and the overall challenge to infer the presence of hyperons in neutron stars, these findings are important as a new route to answer the outstanding question about hyperonic degrees of freedom in high-density matter.

description: We briefly review the five possible real polynomial solutions of hypergeometric differential equations. Three of them are the well known classical orthogonal polynomials, but the other two are different with respect to their orthogonality properties. We then focus on the family of polynomials which exhibits a finite orthogonality. This family, to be referred to as the Romanovski polynomials, is required in exact solutions of several physics problems ranging from quantum mechanics and quark physics to random matrix theory. It appears timely to draw attention to it by the present study. Our survey also includes several new observations on the orthogonality properties of the Romanovski polynomials and new developments from their Rodrigues formula.

description: For a quiver with potential, Derksen, Weyman and Zelevinsky defined a combinatorial transformation - mutations. Mukhopadhyay and Ray, on the other hand, tell us how to compute Seiberg dual quivers for some quivers with potentials through a tilting procedure, thus obtaining derived equivalent algebras. In this text, we compare mutations with the concept of Seiberg duality, concluding that for a certain class of potentials (the good ones) mutations coincide with Seiberg duality, therefore giving derived equivalences.

description: Health care delivery occurs within a complex organization which have different professional figures. Competing priorities within this structure of health care often result in conflicts between the work teams. In order to better understand the conflict among Medical Health Manager and subordinates the approach requires a general comprehension of the context and the different impacting variables. Infact the workers are becoming more and more interdependent in their actions and responsible for more decision-making processes. These changes mean new types of conflicts may arise among different groups of workers than were experienced in bureaucratically structured organizations (Janssen, Van de Vliert & Veenstra, 1999). On this basis, the research question and the hypotheses that address this study arise from analysis of the literature. The first purpose is to know how conflict styles are defined in academic literature; the second purpose is to understand the conflict style in a sample of Medical Health Manager.

description: Nowadays the provision of social services represents one of the most relevant challenges for a Municipality, due to the growing needs of people asking for more care and to the reduction of resources. The present research analyzes in-depth the experience of a public network created among a group of small Municipalities in Veneto Region, in North-East of Italy, searching to redesign these services, with attention to both effectiveness and efficiency.  It started in 2012 and it is still ongoing towards its complete definition.

Specifically, the study focuses on the role of the different identities involved into the whole process, from the first stage aiming to define the conditions of a new pluralistic configuration for social services based to the development of a strategic and operative alliance.

The case study is an interesting example for public institutions engaged in winning the challenge for a better government in time of resource constraints and institutional pressure towards such kind of initiatives.

description: Spatial resolution in optical microscopy has traditionally been treated as a fixed parameter of the optical system. Here, we present an approach to enhance transverse resolution in beam-scanned optical coherence tomography (OCT) beyond its aberration-free resolution limit, without any modification to the optical system. Based on the theorem of invariance of information capacity, resolution-enhanced (RE)-OCT navigates the exchange of information between resolution and signal-to-noise ratio (SNR) by exploiting efficient noise suppression via coherent averaging and a simple computational bandwidth expansion procedure. We demonstrate a resolution enhancement of 1.5 times relative to the aberration-free limit while maintaining comparable SNR in silicone phantom. We show that RE-OCT can significantly enhance the visualization of fine microstructural features in collagen gel and ex vivo mouse brain. Beyond RE-OCT, our analysis in the spatial-frequency domain leads to an expanded framework of information capacity and resolution in coherent imaging that contributes new implications to the theory of coherent imaging. RE-OCT can be readily implemented on most OCT systems worldwide, immediately unlocking information that is beyond their current imaging capabilities, and so has the potential for widespread impact in the numerous areas in which OCT is utilized, including the basic sciences and translational medicine.

description: The effects of particle discreteness in N-body simulations of Lambda Cold Dark Matter (LambdaCDM) are still an intensively debated issue. In this paper we explore such effects, taking into account the scatter caused by the randomness of the initial conditions, and focusing on the statistical properties of the cosmological density field. For this purpose, we run large sets of LambdaCDM simulations and analyse them using a large variety of diagnostics, including new and powerful wavelet statistics. Among other facts, we point out (1) that dynamical evolution does not propagate discreteness noise up from the small scales at which it is introduced, and (2) that one should aim to satisfy the condition epsilon ~ 2d, where "epsilon" is the force resolution and "d" is the interparticle distance. We clarify what such a condition means, and how to implement it in modern cosmological codes.

description: We adopt a geometric perspective on Fock space to provide two complementary insights into the eigenstates in many-body-localized fermionic systems. On the one hand, individual many-bodylocalized eigenstates are well approximated by a Slater determinant of single-particle orbitals. On the other hand, the orbitals of different eigenstates in a given system display a varying, and generally imperfect, degree of compatibility, as we quantify by a measure based on the projectors onto the corresponding single-particle subspaces. We study this incompatibility between states of fixed and differing particle number, as well as inside and outside the many-body-localized regime. This gives detailed insights into the emergence and strongly correlated nature of quasiparticle-like excitations in many-body localized systems, revealing intricate correlations between states of different particle number down to the level of individual realizations.

Pudlo Pudlat : images of change

Publisher: name: University of British Columbia
Year: 2010

description: Two problems in the appreciation of Inuit art are firstly, the commercial cornerstone and, secondly, the cultural gap, in most cases, between the viewer and the artist. With regard to the first, although commercialism is a fact, it should not cloud the obvious visual and informative expressiveness of the works of such artists as Pudlo Pudlat, the subject of this thesis. Rather than dwell upon the negative aspects of commercialism, we concentrate on the benefits. For, without the monetary impulse, many artists might not have begun to externalize, and thereby record, the events and feelings associated with a culture both removed from our own and also undergoing the dramatic changes of acculturation. This is the essence of the second problem. It is one which faces anybody wishing to approach the unfamiliar. In this particular case it required the reading of sociological, anthropological, and psychological abstracts, among others. None of these as good as the primary experience, yet all geared to helping lower the barriers of one's own cultural bias. In short, extensive background information on traditional and acculturational life in the North is a necessity. Pudlo has been drawing for over twenty years, since the beginning of print-making. In reviewing the development of his oeuvre, one comes to an appreciation of his work and of the development of print-making in the Canadian Arctic in general, as well as in Cape Dorset, specifically. The themes of Pudlo's prints reveal his brand of historicism to be more than a documentation of traditional life in the North. The hunter-turned-artist infuses information with a profound depth of emotion. His shamanic images educate the less well informed and surely evoke memories and feelings in the initiated. Portrayals of the land and animals project the Inuit's long-standing respect for, and intimate bond with, nature. Pudlo is one of the very few Inuit artists to include modern objects in his drawings. In his choice and use of these motifs, he creates a continuum between his shamanic past and the rapidly changing present.

description: Interest has focussed recently on low energy implications of a nontrivial scale invariant sector of an effective field theory with an IR fixed point, manifest in terms of ``unparticles'' with peculiar properties. If unparticle stuff exists it could couple to the stress tensor and mediate a new 'fifth' force which we call 'ungravity' arising from the exchange of unparticles between massive particles, which in turn could modify the inverse square law. Under the assumption of strict conformal invariance in the hidden sector down to low energies, we compute the lowest order ungravity correction to the Newtonian gravitational potential and find scale invariant power law corrections of type $(R_{G}/r)^{2d_{\cal U} -1}$ where $d_{\cal U}$ is an anomalous unparticle dimension and $R_{G}$ is a characteristic length scale where the ungravity interactions become significant. $d_{\cal U}$ is constrained to lie the range $ d_{\cal U} > 3 (2)$ for a spin 2 (spin 0) unparticle coupling to the stress tensor (and its trace) and leads to modification of the inverse square law with $r$ dependence in the range between $1/r^{4+2δ} (δ>0)$, while extra dimension models with warping modify the force law with corrections beginning with terms O$(1/r^3)$ for small $r$ but exponentially suppressed for large $r$. Thus a discrimination between extra dimension models and ungravity is possible in future improved submillimeter tests of gravity.

description: Recent PVLAS data put stringent constraints on the measurement of birefringence and dichroism of electromagnetic waves travelling in a constant and homogeneous magnetic field. There have been theoretical predictions in favour of such phenomena when appropriate axion-electromagnetic coupling is assumed. Origin of such a coupling can be traced in a low energy string action from the requirement of quantum consistency. The resulting couplings in such models are an artifact of the compactification of the extra dimensions present inevitably in a string scenario. The moduli parameters which encode the compact manifold therefore play a crucial role in determining the axion-photon coupling. In this work we examine the possible bounds on the value of compact modulus that emerge from the experimental limits on the coupling obtained from the PVLAS data. In particular we focus into the Randall-Sundrum (RS) type of warped geometry model whose modulus parameter is already restricted from the requirement of the resolution of gauge hierarchy problem in connection with the mass of the Higgs. We explore the bound on the modulus for a wide range of the axion mass for both the birefringence and the dichroism data in PVLAS. We show that the proposed value of the modulus in the RS scenario can only be accommodated for axion mass $\gsim$ 0.3 eV.

Collapsing and static thin massive charged dust shells in a Reissner-Nordström black hole background in higher dimensions

description: The problem of a spherically symmetric charged thin shell of dust collapsing gravitationally into a charged Reissner-Nordström black hole in $d$ spacetime dimensions is studied within the theory of general relativity. Static charged shells in such a background are also analyzed. First a derivation of the equation of motion of such a shell in a $d$-dimensional spacetime is given. Then a proof of the cosmic censorship conjecture in a charged collapsing framework is presented, and a useful constraint which leads to an upper bound for the rest mass of a charged shell with an empty interior is derived. It is also proved that a shell with total mass equal to charge, i.e., an extremal shell, in an empty interior, can only stay in neutral equilibrium outside its gravitational radius. This implies that it is not possible to generate a regular extremal black hole by placing an extremal dust thin shell within its own gravitational radius. Moreover, it is shown, for an empty interior, that the rest mass of the shell is limited from above. Then several types of behavior of oscillatory charged shells are studied. In the presence of a horizon, it is shown that an oscillatory shell always enters the horizon and reemerges in a new asymptotically flat region of the extended Reissner-Nordström spacetime. On the other hand, for an overcharged interior, i.e., a shell with no horizons, an example showing that the shell can achieve a stable equilibrium position is presented. The results presented have applications in brane scenarios with extra large dimensions, where the creation of tiny higher dimensional charged black holes in current particle accelerators might be a real possibility, and generalize to higher dimensions previous calculations on the dynamics of charged shells in four dimensions.

description: Language model based methods are powerful techniques for text classification. However, the models have several shortcomings. (1) It is difficult to integrate human knowledge such as keywords. (2) It needs a lot of resources to train the models. (3) It relied on large text data to pretrain. In this paper, we propose Semi-Supervised vMF Neural Topic Modeling (S2vNTM) to overcome these difficulties. S2vNTM takes a few seed keywords as input for topics. S2vNTM leverages the pattern of keywords to identify potential topics, as well as optimize the quality of topics' keywords sets. Across a variety of datasets, S2vNTM outperforms existing semi-supervised topic modeling methods in classification accuracy with limited keywords provided. S2vNTM is at least twice as fast as baselines.

description: We derive semiclassical approximations for wavefunctions, Green's functions and expectation values for classically chaotic quantum systems. Our method consists of applying singular and regular perturbations to quantum Hamiltonians. The wavefunctions, Green's functions and expectation values of the unperturbed Hamiltonian are expressed in terms of the spectral determinant of the perturbed Hamiltonian. Semiclassical resummation methods for spectral determinants are applied and yield approximations in terms of a finite number of classical trajectories. The final formulas have a simple form. In contrast to Poincare surface of section methods, the resummation is done in terms of the periods of the trajectories.

An investigation of intuitive thinking as it relates to the visual decision-making process
Creators: name: Dyer, Marilyn Rose
Publisher: name: University of British Columbia
Year: 2010

description: This thesis advances the proposition that intuitive thinking, although difficult to observe, explain or measure, can be the subject of investigation and is amenable to analysis. The nature of intuitive thinking is reviewed, and its characteristics applied to an observable situation during a summer school course in which the subjects and the instructor/researcher recorded their awareness of intuitive thinking in journal form while involved in solving a variety of visual and creative problems. It is shown through the analysis of these evidences that four basic types of intuitive thinking are used during the creative problem-solving process. Further analysis shows that thinkers are sensitive to a variety of external influences, which either inhibit or facilitate intuitive behaviour. The study concludes that it is useful for educators involved in visual problem-solving activities to be cognizant of the physical and psychological factors that influence intuitive thinking and that it is possible to cultivate those heuristic behaviours which facilitate this form of non-deliberate thinking.

description: It is of high interest, in the context of Adiabatic Quantum Computation, to better understand the complex dynamics of a quantum system subject to a time-dependent Hamiltonian, when driven across a quantum phase transition. We present here such a study in the Lipkin-Meshkov-Glick (LMG) model with one variable parameter. We first display numerical results on the dynamical evolution across the LMG quantum phase transition, which clearly shows a pronounced effect of the spectral avoided level crossings. We then derive a phenomenological (classical) transition model, which already shows some closeness to the numerical results. Finally, we show how a simplified quantum transition model can be built which strongly improve the classical approach, and shed light on the physical processes involved in the whole LMG quantum evolution. From our results, we argue that the commonly used description in term of Landau-Zener transitions is not appropriate for our model.

description: We consider an Euclidean supersymmetric field theory in $Z^3$ given by a supersymmetric $Φ^4$ perturbation of an underlying massless Gaussian measure on scalar bosonic and Grassmann fields with covariance the Green's function of a (stable) Lévy random walk in $Z^3$. The Green's function depends on the Lévy-Khintchine parameter $α={3+ε\over 2}$ with $00$ sufficiently small and initial parameters held in an appropriate domain the existence of a global renormalization group trajectory uniformly bounded on all renormalization group scales and therefore on lattices which become arbitrarily fine. At the same time we establish the existence of the critical (stable) manifold. The interactions are uniformly bounded away from zero on all scales and therefore we are constructing a non-Gaussian supersymmetric field theory on all scales. The interest of this theory comes from the easily established fact that the Green's function of a (weakly) self-avoiding Lévy walk in $Z^3$ is a second moment (two point correlation function) of the supersymmetric measure governing this model. The control of the renormalization group trajectory is a preparation for the study of the asymptotics of this Green's function.

description: We investigate the conjecture by Sikora, Stawarz & Lasota (2007) that the observed AGN--radio-loudness bimodality can be explained by the morphology-related bimodality of black-hole spin distribution in the centers of galaxies: central black holes in giant elliptical galaxies may have (on average) much larger spins than black holes in spiral/disc galaxies. We study how accretion from a warped disc influences the evolution of black hole spins and conclude that within the cosmological framework, where the most massive BHs have grown in mass via merger driven accretion, one indeed expects most supermassive black holes in elliptical galaxies to have on average higher spin than black holes in spiral galaxies, where random, small accretion episodes (e.g. tidally disrupted stars, accretion of molecular clouds) might have played a more important role.

description: Teenager detection is an important case of the age detection task in social media, which aims to detect teenage users to protect them from negative influences. The teenager detection task suffers from the scarcity of labelled data, which exacerbates the ability to perform well across social media platforms. To further research in teenager detection in settings where no labelled data is available for a platform, we propose a novel cross-platform framework based on Adversarial BERT. Our framework can operate with a limited amount of labelled instances from the source platform and with no labelled data from the target platform, transferring knowledge from the source to the target social media. We experiment on four publicly available datasets, obtaining results demonstrating that our framework can significantly improve over competitive baseline models on the cross-platform teenager detection task.

description: Connectivity is a fundamental structural feature of a network that determines the outcome of any dynamics that happens on top of it. However, an analytical approach to obtain connection probabilities between nodes associated to paths of different lengths is still missing. Here, we derive exact expressions for random-walk connectivity probabilities across any range of numbers of steps in a generic temporal, directed and weighted network. This allows characterizing explicit connectivity realized by causal paths as well as implicit connectivity related to motifs of three nodes and two links called here pitchforks. We directly link such probabilities to the processes of tagging and sampling any quantity exchanged across the network, hence providing a natural framework to assess transport dynamics. Finally, we apply our theoretical framework to study ocean transport features in the Mediterranean Sea. We find that relevant transport structures, such as fluid barriers and corridors, can generate contrasting and counter-intuitive connectivity patterns bringing novel insights into how ocean currents drive seascape connectivity.

description: Fibres of ultralong and aligned carbon nanotubes (CNT) have axial properties above reference engineering materials, proving to be exceptional materials for application in structural composites, energy storage and other devices. For CNT fibres produced by direct spinning from floating catalyst chemical vapor deposition (FCCVD), a scaled-up method, the challenge is to simultaneously achieve high process conversion and high-performance properties. This work presents a parametric study of the CNT fibre spinning process by establishing the relation between synthesis conditions, molecular composition (i.e. CNT type), fibre mechanical and electrical properties, and conversion. It demonstrates tensile properties (strength 2.1 N/tex, modulus 107 N/tex) above some carbon fibres, combined with carbon conversion about 5%, significantly above literature on similar materials. The combined improvement in conversion and properties is obtained by conducing the reaction at high temperature (1300 °C), using toluene as a carbon source, and through adjustment of the promotor to carbon ratio (S/C) to favor formation of few-layer, collapsed CNTs that maximize packing at relatively high conversions. Lower S/C ratios produce low-defect single-wall CNT, but weaker fibres. An increase in electrical conductivity to 3 x 10^5 S/m is also observed, with the data suggesting a correlation with longitudinal modulus.

description: We present high-resolution echelle spectra of [Ne II] 12.81 micron emission from the classical T Tauri star (CTTS) TW Hya obtained with MICHELLE on Gemini North. The line is centered at the stellar radial velocity and has an intrinsic FWHM of 21\pm 4 km/s. The line width is broader than other narrow emission lines typically associated with the disk around TW Hya. If formed in a disk, the line broadening could result from turbulence in a warm disk atmosphere, Keplerian rotation at an average distance of 0.1 AU from the star, or a photoevaporative flow from the optically-thin region of the disk. We place upper limits on the [Ne II] emission flux from the CTTSs DP Tau and BP Tau.

description: The pressure on firms to be socially responsible continuously increases. Social initiatives, however, are not without controversy. Drawing from stakeholder theory, and the main literature on engagement and social enterprise, our research aims to verify the role of the social dimension as a driver of active stakeholder engagement in the social enterprise domain. The research project is based on a survey involving 268 active stakeholders (both internal and external) of 12 Italian SEs. Based on the structural equation modelling technique, our results provide empirical evidence on the antecedents of engagement, distinguishing between job and organization engagement. They confirm the relevance of the social meaningfulness of the work and of adherence to the social values of the organization as pertinent and appropriate engagement drivers.

description: Drawing on social media and identity literatures our study aims at investigating the use of social media in the recruitment process by adopting the job seekers’ perspective. Using a qualitative methodology with the analysis of pre and post task diaries made by 171 Millennials, the paper explores their behaviors and the tools they used in searching for a job position. Furthermore, the paper investigates how online identity and its co-creation process influence Millennials’ willingness to use social media for recruitment purposes. Lastly, the research aims at exploring if and, potentially, how professional and non-professional social media, with their different features, users and goals, are constantly changing the recruitment process, thus offering suggestions for the design of effective recruitment practices.

description: Optically driven electronic spins coupled in quantum dots to nuclear spins show a pre-pulse signal (revival amplitude) after having been trained by long periodic sequences of pulses. The size of this revival amplitude depends on the external magnetic field in a specific way due to the varying commensurability of the nuclear Larmor precession period with the time $T_\text{rep}$ between two consecutive pulses. In theoretical simulations, sharp dips occur at fields when an integer number of precessions fits in $T_\text{rep}$; this feature could be used to identify nuclear isotopes spectroscopically. But these sharp and characteristic dips have not (yet) been detected in experiment. We study whether the nuclear quadrupolar interaction is the reason for this discrepancy because it perturbs the nuclear precessions. But our simulations show that the absolute width of the dips and their relative depth are not changed by quadrupolar interactions. Only the absolute depth decreases. We conclude that quadrupolar interaction alone cannot be the reason for the absence of the characteristic dips in experiment.
