description: We discuss the method of conformal mappings applied to perturbative QCD. The approach is based on the Borel-Laplace integral regulated with the principal value prescription and the expansion of the Borel transform in powers of the variable which performs the conformal mapping of the cut Borel plane onto the unit disk. We write down the expression of the conformal mapping for the most general location of the singularities of the Borel transform and review the properties of the corresponding expansions of the correlators. Unlike the standard perturbative expansions, which are divergent, the modified expansions have a tamed behaviour at large orders and may even converge under some conditions. On the other hand, the expansion functions exhibit nonperturbative features similar to those of the expanded function. Using these properties, it was suggested recently that the expansions based on the conformal mapping of the Borel plane may provide an alternative to the standard OPE. We briefly review the arguments in favour of this conjecture and discuss the application of the method to the Adler function for massless quarks and the static quark self-energy calculated in lattice QCD.

description: Crosstalk is a leading source of failure in multiqubit quantum information processors. It can arise from a wide range of disparate physical phenomena, and can introduce subtle correlations in the errors experienced by a device. Several hardware characterization protocols are able to detect the presence of crosstalk, but few provide sufficient information to distinguish various crosstalk errors from one another. In this article we describe how gate set tomography, a protocol for detailed characterization of quantum operations, can be used to identify and characterize crosstalk errors in quantum information processors. We demonstrate our methods on a two-qubit trapped-ion processor and a two-qubit subsystem of a superconducting transmon processor.

A purely reflective large wide-field telescope

subject: FOS: Physical sciences

description: Two versions of a fast, purely reflective Paul-Baker type telescope are discussed, each with an 8.4-m aperture, 3 deg diameter flat field and f/1.25 focal ratio. The first version is based on a common, even asphere type of surface with zero conic constant. The primary and tertiary mirrors are 6th order aspheres, while the secondary mirror is an 8th order asphere (referred to here for brevity, as the 6/8/6 configuration). The D_80 diameter of a star image varies from 0''.18 on the optical axis up to 0''.27 at the edge of the field (9.3-13.5 mcm). The second version of the telescope is based on a polysag surface type which uses a polynomial expansion in the sag z, r^2 = 2R_0z - (1+b)z^2 + a_3 z^3 + a_4 z^4 + ... + a_N z^N, instead of the common form of an aspheric surface. This approach results in somewhat better images, with D_80 ranging from 0''.16 to 0''.23, using a lower-order 3/4/3 combination of powers for the mirror surfaces. An additional example with 3.5-m aperture, 3.5 deg diameter flat field, and f/1.25 focal ratio featuring near-diffraction-limited image quality is also presented.

An economic analysis of multiple use forestry using FORPLAN-Version 2
Creators: name: Hackett, James Simpson
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines a mathematical programming model called FORPLAN as a planning tool for strategic analysis of forest management alternatives. This model uses economic efficiency as the objective of forest management planning. The dynamic theory of multiple use forestry is analyzed and expressed as a linear programming analogue in FORPLAN. The main weakness of this theory is that it focuses on single stand analysis. Even so, forest wide constraints applied to certain FORPLAN formulations compensate for this weakness. A strata-based forest management problem is developed to show the economic implications of four forest management alternatives: (1) timber production; (2) timber production subject to a non-declining yield limitation; (3) timber and black-tailed deer (Odocolieus hemionus columbianus) production; and (4) timber and black-tailed deer production, again including a non-declining yield of timber. Demand curves for two analysis areas and a supply curve for deer winter range are developed using parametric analysis. The ability of FORPLAN to address economic implications of current forest management policies is discussed. Economic analysis of forest management alternatives would play a useful role in forest planning in British Columbia. The need for such evaluation is underlined by the ever increasing number of resource conflicts caused by the dominance of the timber industry and the continually growing demand for other forest resources. Three conclusions are drawn from this study. First, FORPLAN has the technical capability to be an effective tool for analyzing strategic multiple use plans under economic efficiency criteria. It does not have the timber bias of earlier models and the capability of FORPLAN to integrate area and strata-based variables makes it a very powerful model. Second, parametric programming of FORPLAN solutions provides marginal analysis for inputs and outputs. Comparative examination of these curves and their elasticities provide information about the relative importance of different analysis areas. Lastly, managing for timber and hunting services for black-tailed deer by preserving old growth winter range is not an economically viable management option. The relative value of the timber is significantly greater than the hunting services for the deer that it is just not worth managing for both.

description: The spectral problem for the quantum dispersionless Korteweg-de Vries (KdV) hierarchy, aka the quantum Hopf hierarchy, is solved by Dubrovin. In this article, following Dubrovin, we study Buryak-Rossi's quantum KdV hierarchy. In particular, we prove a symmetry property and a non-degeneracy property for the quantum KdV Hamiltonians. On the basis of this we construct a complete set of common eigenvectors. The analysis underlying this spectral problem implies certain vanishing identities for combinations of characters of the symmetric group. We also comment on the geometry of the spectral curves of the quantum KdV hierarchy and we give a representation of the quantum dispersionless KdV Hamiltonians in terms of multiplication operators in the class algebra of the symmetric group.

description: The magnetic critical properties of two-dimensional Ising spin glasses are controversial. Using exact ground state determination, we extract the properties of clusters flipped when increasing continuously a uniform field. We show that these clusters have many holes but otherwise have statistical properties similar to those of zero-field droplets. A detailed analysis gives for the magnetization exponent delta = 1.30 +/- 0.02 using lattice sizes up to 80x80; this is compatible with the droplet model prediction delta = 1.282. The reason for previous disagreements stems from the need to analyze both singular and analytic contributions in the low-field regime.

description: This book collects contributions on questions of justice. It proposes a reflection on justice observed from different disciplinary perspectives (organization, philosophy, labor law, economics, work psychology) concerning the basic assumptions underlying the research approaches on this topic. Then, the book considers justice in relation to different issues that are widely debated in the social arena (corporate governance, organizational design, well-being, digitalization of work processes, smart working). A critical point of view on the different positions is adopted. We believe that recognizing the specificities of single disciplines and their defining and applicative problems is a fundamental premise in order to face the new challenges that a subject as ancient as justice seems to bring to the forefront of today’s society.
Thin elastic shells with variable thickness for lithospheric flexure of one-plate planets

description: Planetary topography can either be modeled as a load supported by the lithosphere, or as a dynamical effect due to lithospheric flexure caused by mantle convection. In both cases the response of the lithosphere to external forces can be calculated with the theory of thin elastic plates or shells. On one-plate planets the spherical geometry of the lithospheric shell plays an important role in the flexure mechanism. So far the equations governing the deformations and stresses of a spherical shell have only been derived under the assumption of a shell of constant thickness. However local studies of gravity and topography data suggest large variations in the thickness of the lithosphere. In this article we obtain the scalar flexure equations governing the deformations of a thin spherical shell with variable thickness or variable Young's modulus. The resulting equations can be solved in succession, except for a system of two simultaneous equations, the solutions of which are the transverse deflection and an associated stress function. In order to include bottom loading generated by mantle convection, we extend the method of stress functions to include loads with a toroidal tangential component. We further show that toroidal tangential displacement always occurs if the shell thickness varies, even in the absence of toroidal loads. We finally prove that the degree-one harmonic components of the transverse deflection and of the toroidal tangential displacement are independent of the elastic properties of the shell and are associated with translational and rotational freedom. The flexure equations for a shell of variable thickness are useful not only for the prediction of the gravity signal in local admittance studies, but also for the construction of stress maps in tectonic analysis.

description: Influenced by the field of Computer Vision, Generative Adversarial Networks (GANs) are often adopted for the audio domain using fixed-size two-dimensional spectrogram representations as the "image data". However, in the (musical) audio domain, it is often desired to generate output of variable duration. This paper presents VQCPC-GAN, an adversarial framework for synthesizing variable-length audio by exploiting Vector-Quantized Contrastive Predictive Coding (VQCPC). A sequence of VQCPC tokens extracted from real audio data serves as conditional input to a GAN architecture, providing step-wise time-dependent features of the generated content. The input noise z (characteristic in adversarial architectures) remains fixed over time, ensuring temporal consistency of global features. We evaluate the proposed model by comparing a diverse set of metrics against various strong baselines. Results show that, even though the baselines score best, VQCPC-GAN achieves comparable performance even when generating variable-length audio. Numerous sound examples are provided in the accompanying website, and we release the code for reproducibility.

description: In Weyl semimetals the application of parallel electric and magnetic fields leads to valley polarization -- an occupation disbalance of valleys of opposite chirality -- a direct consequence of the chiral anomaly. In this work, we present numerical tools to explore such nonequilibrium effects in spatially confined three-dimensional systems with a variable disorder potential, giving exact solutions to leading order in the disorder potential and the applied electric field. Application to a Weyl-metal slab shows that valley polarization also occurs without an external magnetic field as an effect of chiral anomaly "trapping": Spatial confinement produces chiral bulk states, which enable the valley polarization in a similar way as the chiral states induced by a magnetic field. Despite its finite-size origin, the valley polarization can persist up to macroscopic length scales if the disorder potential is sufficiently long ranged, so that direct inter-valley scattering is suppressed and the relaxation then goes via the Fermi-arc surface states.

description: Spin-dependent transport measurements through a double quantum dot are a valuable tool for detecting both the coherent evolution of the spin state of a single electron as well as the hybridization of two-electron spin states. In this paper, we discuss a model that describes the transport cycle in this regime, including the effects of an oscillating magnetic field (causing electron spin resonance) and the effective nuclear fields on the spin states in the two dots. We numerically calculate the current flow due to the induced spin flips via electron spin resonance and we study the detector efficiency for a range of parameters. The experimental data are compared with the model and we find a reasonable agreement.

description: pyGDM is a python toolkit for electro-dynamical simulations of individual nano-structures, based on the Green Dyadic Method (GDM). pyGDM uses the concept of a generalized propagator, which allows to solve cost-efficiently monochromatic problems with a large number of varying illumination conditions such as incident angle scans or focused beam raster-scan simulations. We provide an overview of new features added since the initial publication [Wiecha, Computer Physics Communications 233, pp.167-192 (2018)]. The updated version of pyGDM is implemented in pure python, removing the former dependency on fortran-based binaries. In the course of this re-write, the toolkit's internal architecture has been completely redesigned to offer a much wider range of possibilities to the user such as the choice of the dyadic Green's functions describing the environment. A new class of dyads allows to perform 2D simulations of infinitely long nanostructures. While the Green's dyads in pyGDM are based on a quasistatic description for interfaces, we also provide as new external python package pyGDM2_retard a module with retarded Green's tensors for an environment with two interfaces. We have furthermore added functionalities for simulations using fast-electron excitation, namely electron energy loss spectroscopy and cathodoluminescence. Along with several further new tools and improvements, the update includes also the possibility to calculate the magnetic field and the magnetic LDOS inside nanostructures, field-gradients in- and outside a nanoparticle, optical forces or the chirality of nearfields. All new functionalities remain compatible with the evolutionary optimization module of pyGDM for nano-photonics inverse design.

title: Performing stragismo and counter-spectacularisation: Italian right-wing terrorism and its legacies

subject: Theatre and performance

description: This practice-based PhD project is interested in how spectacularity, particularly the spectacle of political violence, influences collective memory. In pursuing this analysis, the project questions how spectacularity permeates the public discourse through the language of power and the media. The case study is the partially erased collective memory of Italian right-wing political violence (1969-1980) and its intergenerational transmission. During the 1970s, Italy experienced a high number of terrorist attacks, perpetrated by both left- and right-wing extremists. Due to judicially verified collusion with secret services and political personalities, the right-wing bombing attacks were and are known as “stragi di stato” [state massacres] by a large segment of the population. However, the historical and social contexts of these attacks, along with the factual and judicial truths, are largely forgotten. This project asks what factors contributed to this collective erasure and what strategies, drawn from theatre and performance theory and practice, can be implemented to develop collective memory. The project theorises ‘counterspectacularisation’ as a set of strategies created by the public, as well as by theatre and performance practitioners, in response to the spectacular violence of terrorists. Practice and theoretical examination inform each other, with counterspectacularisation being analysed through theories of theatre and performance, case studies of performances and and four original artworks that I developed as part of my personal practice, all of which examine how to address memory gaps ethically and respectfully.
Absence of obvious tidal tails around the globular cluster NGC 6397

description: In this work, we use $N-$body simulations performed on GPU to trace the past 10 Gyr dynamical history of a globular cluster (GC) similar to NGC~6397 in the tidal field of a Milky Way-like galaxy and we compare our simulated GCs with data from the third Gaia early data release. Our simulations predict, in contrast to what is deduced from the data, that such a cluster should present strong and extended tidal tails by more than 6 Gyr ago (right after the first third of its life), exceeding 1 kpc of length, and should be roughly disrupted by current time. We analyzed each of our initial conditions, such as initial mass and density parameters, as well as the dark matter shape, and we argue that the most likely reason for such discrepancy between the data and our simulations is related to the fact that we consider a purely baryonic cluster in the beginning of each model we test. We discuss that if our globular cluster was initially embedded in a dark matter minihalo, the latter could act as a protecting envelope, which prevents the tidal stripping of the luminous matter, while being itself gradually disrupted and removed in the course of the cluster evolution. This could explain why an insignificant amount of dark matter is required to describe the velocity dispersion in NGC~6397, up to at least a few half-mass radii.

description: The hierarchy of conformally invariant k-th powers of the Laplacian acting on a scalar field with scaling dimensions $Δ_{(k)}=k-d/2$, k=1,2,3 as obtained in the recent work [1] is rederived using the Fefferman-Graham d+2 dimensional ambient space approach. The corresponding mysterious "holographic" structure of these operators is clarified. We explore also the d+2 dimensional ambient space origin of the Ricci gauging procedure proposed by A. Iorio, L. O'Raifeartaigh, I. Sachs and C. Wiesendanger as another method of constructing the Weyl invariant Lagrangians. The corresponding \emph{gauged} ambient metric, Fefferman-Graham expansion and extended Penrose-Brown-Henneaux transformations are proposed and analyzed.

Use of benefit cost analysis with equity considerations to evaluate social forestry projects in India
Creators: name: Khetarpal, S. K.
Publisher: name: University of British Columbia
Year: 2010

description: Benefit cost analysis (BCA) has been found to be an inadequate tool for evaluating social forestry projects because of its indifference, to income distribution and inability to evaluate some environmental benefits (Sirivastava and Pant, 1979). Application of BCA, with consideration of income distribution, to the evaluation of social forestry projects in India is the subject of this thesis. A social forestry project has been implemented since 1982 in Maharashtra State (India) with the help of the Government of the U.S.A. to meet increasing requirements for fuelwood, fodder and small timber, to save existing forests, and to improve income distribution. Most of the village (common) lands included in the project for establishing fuelwood and fodder plantations are degraded and severely overgrazed. More productive but distant public forest lands are also available for establishing plantations. Whether or not the use of public forest lands for establishing fuelwood plantations is socially more efficient than planting on village (common) lands, is investigated and answered. The various approaches to incorporating equity in economic benefits are reviewed and the Squire and Van der Tak (1975) method is used. Five alternative plantation programs are considered in this thesis. Three of the plantation programs have been implemented since 1982 under the Maharashtra State social forestry project. The other two plantation' programs; are plantation programs on the public forest lands proposed to meet social forestry objectives. Costs other than the labour employed during the off-agriculture season have been valued at market prices. The labour cost during the off-agriculture season is valued at the shadow price of labour. A methodology is established for valuation of indirect benefits from saving the forests from deforestation. Social benefits are valued by attaching equity weights. From the results of the economic and social benefit cost analysis it is concluded that the program of distributing free seedlings to the farmers for planting on the field boundaries is economically and socially far more efficient than any other plantation program considered in this thesis. Establishing of fuelwood and fodder plantations on public forest lands is economically and socially more efficient than establishing plantations on degraded and severely overgrazed village (common) lands.

description: We describe XMM-Newton observations taken 4.3 days prior to and 1.5 days subsequent to two remarkable events that were detected with Swift on 2006 September 21 from the candidate magnetar CXOU J164710.2-455216: (1) a 20 ms burst with an energy of 1e37 erg (15-150 keV), and (2) a rapid spin-down (glitch) with a fractionap period change of 1e-4. We find that the luminosity of the pulsar increased by a factor of 100 in the interval between observations, from 1e33 to 1e35 erg/s (0.5-8.0 keV), and that its spectrum hardened. The pulsed count rate increased by a factor of 10 (0.5-8.0 keV), but the fractional rms amplitude of the pulses decreased from 65 to 11 per cent, and their profile changed from being single-peaked to exhibiting three peaks. Similar changes have been observed from other magnetars in response to outbursts, such as that of 1E 2259+586 in 2002 June. We suggest that a plastic deformation of the neutron star's crust induced a very slight twist in the external magnetic field, which in turn generated currents in the magnetosphere that were the direct cause of the X-ray outburst.

On slow-fading non-separable correlation MIMO systems

description: In a frequency selective slow-fading channel in a MIMO system, the channel matrix is of the form of a block matrix. We propose a method to calculate the limit of the eigenvalue distribution of block matrices if the size of the blocks tends to infinity. We will also calculate the asymptotic eigenvalue distribution of $HH^*$, where the entries of $H$ are jointly Gaussian, with a correlation of the form $E[h_{pj}\bar h_{qk}]= \sum_{s=1}^t Ψ^{(s)}_{jk}\hatΨ^{(s)}_{pq}$ (where $t$ is fixed and does not increase with the size of the matrix). We will use an operator-valued free probability approach to achieve this goal. Using this method, we derive a system of equations, which can be solved numerically to compute the desired eigenvalue distribution.

Further Evidence that the Redshifts of AGN Galaxies May Contain Intrinsic Components
Creators: name: Bell, M. B.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In the decreasing intrinsic redshift (DIR) model galaxies are assumed to be born as compact objects that have been ejected with large intrinsic redshift components, z_(i), out of the nuclei of mature AGN galaxies. As young AGN (quasars) they are initially several magnitudes sub-luminous to mature galaxies but their luminosity gradually increases over 10^8 yrs, as z_(i) decreases and they evolve into mature AGN (Seyferts and radio galaxies). Evidence presented here that low- and intermediate-redshift AGN are unquestionably sub-luminous to radio galaxies is then strong support for this model and makes it likely that the high-redshift AGN (quasars) are also sub-luminous, having simply been pushed above the radio galaxies on a logz-m_(v) plot by the presence of a large intrinsic component in their redshifts. An increase in luminosity below z = 0.06 is also seen. It is associated in the DIR model with an increase in luminosity as the sources mature but, if real, is difficult to interpret in the cosmological redshift (CR) model since at this low redshift it is unlikely to be associated with a higher star formation rate or an increase in the material used to build galaxies. Whether it might be possible in the CR model to explain these results by selection effects is also examined.

The Generation and Dissipation of Interstellar Turbulence - Results from Large Scale High Resolution Simulations

description: We study, by means of adaptive mesh refinement hydro- and magnetohydrodynamical simulations that cover a wide range of scales (from kpc to sub-parsec), the dimension of the most dissipative structures and the injection scale of the turbulent interstellar gas, which we find to be about 75 pc, in agreement with observations. This is however smaller than the average size of superbubbles, but consistent with significant density and pressure changes in the ISM, which leads to the break-up of bubbles locally and hence to injection of turbulence. The scalings of the structure functions are consistent with log-Poisson statistics of supersonic turbulence where energy is dissipated mainly through shocks. Our simulations are different from previous ones by other authors as (i) we do not assume an isothermal gas, but have temperature variations of several orders of magnitude and (ii) we have no artificial forcing of the fluid with some ad hoc Fourier spectrum, but drive turbulence by stellar explosions at the Galactic rate, self-regulated by density and temperature thresholds imposed on the ISM gas.

Zwischen Transfer- und Pionierforschung: Zwölf Problemfelder einer Agenda europabezogener Gewerkschaftsforschung

Year: 2015

description: Based on earlier works that scrutinized the linkage between German trade unions and European integration this article intends to identify twelve systematic approaches to further academic research in the field of history. In order to benefit from the academic research that has been carried out so far an exchange between different disciplines seems to be inevitable. In particular, the conclusions from social sciences have to be taken into account by the humanities in order to draw a more nuanced picture and to rest on a more salient basis for further explorations. The interdisciplinary exchange has to be endorsed by further archive studies and the recourse to genuinely historical approaches.

description: For the past dozen years, UNC-Chapel Hill has been developing a unique, survey-level astronomy curriculum, primarily for undergraduate students, with the goal of significantly boosting STEM enrollments on a national scale, as well as boosting students' technical and research skills. Called "Our Place In Space!", or OPIS!, this curriculum leverages "Skynet" - a global network of ~2 dozen, fully automated, or robotic, professional-grade telescopes that we have deployed at some of the world's best observing sites. The curriculum has now been adopted by ~2 dozen institutions, and we have just received $1.85M from NSF's IUSE program to expand it nationwide, with funding for participating instructors. The curriculum works equally well online as in person.
