Panel: Towards an Integrated Model for Access to Official Microdata in Europe: First Findings from the FP7 DwB Project
Creators: name: Tubaro, Paola
name: Schiller, David
Publisher: name: Zenodo
Year: 2012

description: The session will present for discussions some preliminary outputs from the FP7 Data without Boundaries project about standards and harmonization issues for discovery, metadata, accreditation and access to official microdata within the European context. M. Wittenberg, M.Priddy, J.Sherpherdson ("Desired portal functionality for effective resource discovery on OS data across Europe") present the work undertaken about desired portal functionality for effective resource discovery: researchers expectations, constraints due to diversity in content and technical level of the various resources, metadata issues and identify the next steps for a possible architecture for the portal. C.Jayet, R.Fleureux, A. Mack, Ch. Wolf "(Servicing researchers in the use of European OS microdata") set forth the tools employed to cope with the difficulties encountered in using the existing metadata standards (DDI2 and 3) in the specific European case when documenting study programmes, studies and datasets from numerous institutions and countries and the metadata scheme proposed for documenting European official microdata both at national and European level with the aim of building a Service Centre for OS microdata in Europe. R. Silberman, P. Tubaro, M. Cros, B. Kleiner ("Access to official microdata and researcher accreditation: State of the art and future perspectives in Europe") map similarities and differences in national access and accreditation arrangements while pointing at commonalities for inter-operability and, ideally, adoption of common standards. D. Schiller ("A pilot for an European Remote Access Network - first results and upcoming challenges") presents preliminary outputs about the concept and architecture of a European distributed remote access for confidential official microdata coping with current legal constraints within Europe, security and standard issues, technical feasibility and researchers needs.

description: We study Gabor frames with Hermite window functions. Gröchenig and Lyubarskii provided a sufficient density condition for their frame sets, which leads to what we call the "safety region". For rectangular lattices and Hermite windows of order 4 and higher, we enlarge this safety region by providing new points on the boundary of this region. For this purpose, we employ the Janssen representation of the frame operator to compare its distance to the identity in the operator norm. The calculations lead to estimates on series involving Laguerre polynomials with Gaussian weight functions.

description: Out-of-time-ordered correlators (OTOCs) are of crucial importance for studying a wide variety of fundamental phenomena in quantum physics, ranging from information scrambling to quantum chaos and many-body localization. However, apart from a few special cases, they are notoriously difficult to compute even numerically due to the exponential complexity of generic quantum many-body systems. In this paper, we introduce a machine learning approach to OTOCs based on the restricted-Boltzmann-machine architecture, which features wide applicability and could work for arbitrary-dimensional systems with massive entanglement. We show, through a concrete example involving a two-dimensional transverse field Ising model, that our method is capable of computing early-time OTOCs with respect to random pure quantum states or infinite-temperature thermal ensembles. Our results showcase the great potential for machine learning techniques in computing OTOCs, which open up numerous directions for future studies related to similar physical quantities.

Combining the CP-violating observables of the decays Bd-->pi+pi- and Bs-->K+K- it is possible to extract the gamma angle of the unitarity triangle. The selection of these decays within the current LHCb simulation framework is outlined and the expected annual event yields and background-to-signal ratios are quoted. Then, the results of a study on the sensitivity that LHCb can achieve for the corresponding CP-violating observables are presented.

Subindustria : The Bio-Mechanical Neighbourhood of Tomorrow
Creators: name: Ackerley, Jon
Publisher: name: The University of British Columbia
Year: 2022

description: The suburbs are made possible by sprawling systems of resource extraction, infrastructure, and shipping. The outputs of these systems are accumulated and assembled into recognizable symbols of suburban culture. But the industrial roots of suburbia are obscured by the separation between industry and other suburban typologies. Landscapes of production and landscapes of consumption are kept culturally and physically distant. Land-use mechanisms isolate industrial buildings to minimize their negative effects on surrounding communities. Changing economies distance traditional images of large-scale industry from the Canadian cultural consciousness. The result is a growing invisibility of industry and its role in suburban systems. This invisibility poses an existential threat; not only does it obscure the reality of suburban structures, but it also conceals the systematic devastation of the environment perpetrated by large-scale industrial activity. This thesis proposes a new typology - a community that merges industry and domesticity, melding their iconography together and making industrial systems visible. Here, we can learn what it means to live with industry, and how flattening landscapes of consumption and landscapes of productions can present new opportunities for suburbia. The result is Subindustria, a bio-mechanical community coming soon to a strip of land between a cement plant and a major highway.

description: Family Replicated Gauge Group models of the type SU(n)^N\times SU(m)^N, (SMG)^3 and (SMG\times U(1)_{B-L})^3 are reviewed, where SMG=SU(3)_{c}\times SU(2)_{L}\times U(1)_{Y} is the gauge symmetry group of the Standard Model, $B$ is the baryon and $L$ is the lepton numbers, respectively. It was shown that Family Replicated Gauge Group model of the latter type fits the Standard Model fermion masses and mixing angles and describes all neutrino experiment data order magnitudewise using only 5 free parameters -- five vacuum expectation values of the Higgs fields which break the Family Replicated Gauge Group symmetry to the Standard Model. The possibility of [SU(5)]^3 or [SO(10)]^3 unification at the GUT-scale \sim 10^{18} GeV also is briefly considered.

description: Prediction in quantum cosmology requires a specification of the universe's quantum dynamics and its quantum state. We expect only a few general features of the universe to be predicted with probabilities near unity conditioned on the dynamics and quantum state alone. Most useful predictions are of conditional probabilities that assume additional information beyond the dynamics and quantum state. Anthropic reasoning utilizes probabilities conditioned on `us'. This paper discusses the utility, limitations, and theoretical uncertainty involved in using such probabilities. The predictions resulting from various levels of ignorance of the quantum state are discussed including those related to uncertainty in the vacuum of string theory. Some obstacles to using anthropic reasoning to determine this vacuum are described.

Denoising of Imaginary Time Response Functions with Hankel projections

description: Imaginary-time response functions of finite-temperature quantum systems are often obtained with methods that exhibit stochastic or systematic errors. Reducing these errors comes at a large computational cost -- in quantum Monte Carlo simulations, the reduction of noise by a factor of two incurs a simulation cost of a factor of four. In this paper, we relate certain imaginary-time response functions to an inner product on the space of linear operators on Fock space. We then show that data with noise typically does not respect the positive definiteness of its associated Gramian. The Gramian has the structure of a Hankel matrix. As a method for denoising noisy data, we introduce an alternating projection algorithm that finds the closest positive definite Hankel matrix consistent with noisy data. We test our methodology at the example of fermion Green's functions for continuous-time quantum Monte Carlo data and show remarkable improvements of the error, reducing noise by a factor of up to 20 in practical examples. We argue that Hankel projections should be used whenever finite-temperature imaginary-time data of response functions with errors is analyzed, be it in the context of quantum Monte Carlo, quantum computing, or in approximate semianalytic methodologies.

description: We consider the simplest model for $T$ - linear growth of resistivity in metals.

description: We calculate the unpolarized QED Compton scattering cross section in a manifestly covariant way. Our approach allows a direct implementation of the specific kinematical cuts imposed in the experiments, {\it e. g.} HERA-H1. We compare the 'exact' cross section in terms of the structure functions $F_{1,2} (x_B,Q^2)$, assuming the Callan-Gross relation, with the one obtained using the equivalent photon approximation (EPA) as well as with the experimental results. We find that the agreement with the EPA is better in $x_γ$ bins, where $x_γ$ is the fraction of the longitudinal momentum of the proton carried by the virtual photon, compared to the bins in the leptonic variable $x_l$.

description: Quantum Chromodynamics admits a CP-violating contribution to the action, the $θ$ term, which is expected to give rise to a nonvanishing electric dipole moment of the neutron. Despite intensive search, no CP violations have been found in the strong interaction. This puzzle is referred to as the strong CP problem. There is evidence that CP is conserved in the confining theory, to the extent that color charges are totally screened for $θ> 0$ at large distances. It is not immediately obvious that this implies a vanishing dipole moment though. With this Letter I will close the gap. It is shown that in the infinite volume hadron correlation functions decouple from the topological charge, expressed in terms of the zero modes. The reason is that hadrons have a limited range of interaction, while the density of zero modes vanishes with the inverse root of the volume, thus reducing the probability of finding a zero mode in the vicinity to zero. This implies that CP is conserved in the strong interaction.

Initial Conditions of Inflation in a Bianchi I Universe

description: We investigate the initial conditions of inflation in a Bianchi~I universe that is homogeneous but not isotropic. We use the Eisenhart lift to describe such a theory geometrically as geodesics on a field space manifold. We construct the phase-space manifold of the theory by considering the tangent bundle of the field space and equipping it with a natural metric. We find that the total volume of this manifold is finite for a wide class of inflationary models. We therefore take the initial conditions to be uniformly distributed over it in accordance with Laplace's principle of indifference. This results in a normalisable, reparametrisation invariant measure on the set of initial conditions of inflation in a Bianchi~I universe. We find that this measure favours an initial state in which the inflaton field is at or near its minimum, with a mild preference for some initial anisotropy. Since inflation requires an initial field value with a large displacement from its minimum, we therefore conclude that the theory of inflation requires finely tuned initial conditions.

description: Polyimide-based materials, like Kapton, are widely used in flexible cables and circuitry due to their unique electrical and mechanical characteristics. This study is aimed at investigating the radiopurity of Kapton for use in ultralow background, rare-event physics applications by measuring the $^{238}$U, $^{232}$Th, and $^{nat}$K levels using inductively coupled plasma mass spectrometry. Commercial-off-the-shelf Kapton varieties, measured at approximately 950 and 120 pg/g $^{238}$U and $^{232}$Th (1.2$\times$10$^4$ and 490 $μ$Bq/kg), respectively, can be a significant background source for many current and next-generation ultralow background detectors. This study has found that the dominant contamination is due to the use of dicalcium phosphate (DCP), a nonessential slip additive added during manufacturing. Alternative Kapton materials were obtained that did not contain DCP and were determined to be significantly more radiopure than the commercially-available options with 12 and 19 pg/g $^{238}$U and $^{232}$Th (150 and 77 $μ$Bq/kg), respectively. The lowest radioactivity version produced (Kapton ELJ, which contains an adhesive) was found to contain single digit pg/g levels of $^{238}$U and $^{232}$Th, two-to-three orders of magnitude cleaner than commercial-off-the-shelf options. Moreover, copper-clad polyimide laminates employing Kapton ELJ as the insulator were obtained and shown to be very radiopure at 8.6 and 22 pg/g $^{238}$U and $^{232}$Th (110 and 89 $μ$Bq/kg), respectively.

description: The recently founded Collaborative Research Center (SFB) 882 "From Heterogeneities to Social Inequalities" at the University Bielefeld represents a framework for 17 sub-projects on social inequalities. With the promotion of a Virtual Research Environment (VRE) by the INF project (integral part of the SFB) advisory and developmental services in the domain of information infrastructure will be provided. The VRE combines both a work and a project-specific research platform. The work platform bundles IT resources by bringing together various tools for administration, project management, and time- and location-independent collaboration work in a single environment adapted to researcher's specific working processes. The research component combines data management with further developments of social science methodologies. It provides services for archiving and re-use of datasets and is responsible for the infrastructural and methodological coordination of the data documentation. Almost entire data life-cycle is documented by implementing and applying DDI3 across all projects. In this talk, we present the challenges and barriers in designing and building-up a VRE for the social sciences. We mainly focus on documentation aspects, especially on the unification of varying documentation requirements which came up. Additionally, various key issues of research collaboration, as an outcome of the user requirement analysis, will be discussed.

description: The system of an atom couples to two distinct optical cavities with phase decoherence is studied by making use of a dynamical algebraic method. We adopt the concurrence to characterize the entanglement between atom and cavities or between two optical cavities in the presence of the phase decoherence. It is found that the entanglement between atom and cavities can be controlled by adjusting the detuning parameter. Finally, we show that even if the atom is initially prepared in a maximally mixed state, it can also entangle the two mode cavity fields.

description: Multilayer van der Waals (vdWs) semiconductors have great promising application in high-performance optoelectronic devices. However, the photoconductive photodetectors based on layered semiconductors often suffer from large dark current and high external driven bias voltage. Here, we report a vertical van der Waals heterostructures (vdWHs) consisting of multilayer indium selenide (InSe) and tellurium (Te). The multilayer InSe-Te vdWHs device shows a record high forward rectification ratio greater than 107 at room temperature. Furthermore, an ultrasensitive and broadband photoresponse photodetector is achieved by the vdWHs device with an ultrahigh photo/dark current ratio over 104, a high detectivity of 1013, and a comparable responsivity of 0.45 A/W under visible light illumination with weak incident power. Moreover, the vdWHs device has a photovoltaic effect and can function as a self-powered photodetector (SPPD). The SPPD is also ultrasensitive to the broadband spectra ranging from 300 nm to 1000 nm and is capable of detecting weak light signals. This work offers an opportunity to develop next-generation electronic and optoelectronic devices based on multilayer vdWs structures.

Nature Engaged : An Interactive Approach to Nature-Based Learning
Creators: name: Pitoscia, Sarah
Publisher: name: The University of British Columbia
Year: 2022

description: During the Covid Pandemic, elementary schools experienced a revival of outdoor learning. Educators took the opportunity to curate outdoor learning environments within the existing fabric of elementary schools. However, in their efforts to do so, a clear divide between learning and the outdoors became evident within existing school design and teaching pedagogy. The lack of engagement with nature has had detrimental impacts on the cognitive, physical, and social development of school-aged children. A new approach to learning can improve the health and well-being of students. We can expand beyond the existing walled boundary, to instead approach the entire school site to form a gradient of learning environments from indoors to out. The threshold between these conditions forms dynamic spaces that become the connection piece to the outdoors. Nature can be used as a method of space-making to form transitionary zones that encourage engagement with the landscape. The creation of these spaces can be directly tied into learning objectives where children become active participants in the construction, and maintenance of their learning environments.

description: We report the discovery of extended X-ray emission around the powerful high-redshift quasar GB 1508+5714 at z=4.3, revealed in a long Chandra ACIS observation. The emission feature is 3-4 arcsec away from the quasar core, which corresponds to a projected distance of about 25 kpc. The X-ray spectrum is best fitted with a power law of photon index 1.92+-0.35 (90 per cent c.l.). The X-ray flux and luminosity reach 9.2x10^-15 ergs (0.5-8 keV) and 1.6x10^45 erg s^-1 (2.7-42.4 keV rest frame, Omega_Lambda=0.73, Omega_m=0.27, H_0=71 km s^-1 Mpc^-1), which is about 2 percent of the total X-ray emission of the quasar. We interpret the X-ray emission as inverse Compton scattering of Cosmic Microwave Background photons. The scattering relativistic electron population could either be a quasi-static diffuse cloud fed by the jet, or an outer extension of the jet with a high bulk Lorentz factor. We argue that the lack of an obvious detection of radio emission from the extended component could be a consequence of Compton losses on the electron population, or of a low magnetic field. Extended X-ray emission produced by inverse Compton scattering may be common around high redshift radio galaxies and quasars, demonstrating that significant power is injected into their surrounding by powerful jets.

description: The optical potential without any free parameters for $^7$Li-nucleus interaction system is studied in a microscopic approach. It is obtained by folding the microscopic optical potentials of the constituent nucleons of $^{7}$Li over their density distributions. We employ an isospin-dependent nucleon microscopic optical potential, which is based on the Skyrme nucleon-nucleon effective interaction and derived by using the Green's function method, to be the nucleon optical potential. Harmonic oscillator shell model is used to describe the internal wave function of $^7$Li and get the nucleon density distribution. The $^7$Li microscopic optical potential is used to predict the reaction cross sections and elastic scattering angular distributions for target range from $^{27}$Al to $^{208}$Pb and energy range below 450 MeV. Generally the results can reproduce the measured data reasonably well. In addition, the microscopic optical potential is comparable to a global phenomenological optical potential in fitting the presently existing measured data generally.

description: We analyze the effect of a gate on the conductance of molecules by separately evaluating the gate-induced polarization and the potential shift of the molecule relative to the leads. The calculations use ab initio density functional theory combined with a Green function method for electron transport. For a general view, we study several systems: (1) atomic chains of C or Al sandwiched between Al electrodes, (2) a benzene molecule between Au leads, and (3) (9,0) and (5,5) carbon nanotubes. We find that the polarization effect is small because of screening, while the effect of the potential shift is significant, providing a mechanism for single-molecule transistors.

description: The long-time evolution of a system in interaction with an external environment is usually described by a family of linear maps g_t, generated by master equations of Block-Redfield type. These maps are in general non-positive; a widely adopted cure for this physical inconsistency is to restrict the domain of definition of the dynamical maps to those states for which g_t remains positive. We show that this prescription has to be modified when two systems are immersed in the same environment and evolve with the factorized dynamics g_t x g_t starting from an entangled initial state.

description: Many strongly coupled field theories admit a spectrum of gauge-invariant bound states that includes scalar particles with the same quantum numbers as the vacuum. The challenge naturally arises of how to characterise them. In particular, how can a dilaton---the pseudo-Nambu-Goldstone boson associated with approximate scale invariance---be distinguished from other generic light scalars with the same quantum numbers? We address this problem within the context of gauge-gravity dualities, by analysing the fluctuations of the higher-dimensional gravitational theory. The diagnostic test that we propose consists of comparing the results of the complete calculation, performed by using gauge-invariant fluctuations in the bulk, with the results obtained in the probe approximation. While the former captures the mixing between scalar and metric degrees of freedom, the latter removes by hand the fluctuations that source the dilatation operator of the boundary field-theory. Hence, the probe approximation cannot capture a possible light dilaton, while it should fare well for other scalar particles. We test this idea on a number of holographic models, among which are some of the best known, complete gravity backgrounds constructed within the top-down approach to gauge-gravity dualities. We compute the spectra of scalar and tensor fluctuations, that are interpreted as bound states (glueballs) of the dual field theory, and we highlight those cases in which the probe approximation yields results close to the correct physical ones, as well as those cases where significant discrepancies emerge. We interpret the latter occurrence as an indication that identifying one of the lightest scalar states with the dilaton is legitimate, at least as a leading-order approximation.

description: We present the first results of the angular auto-correlation function of the galaxies detected by the Infrared Array Camera (IRAC) instrument in the First Look Survey (FLS) of the Spitzer Space Telescope. We detect significant signals of galaxy clustering within the survey area. The angular auto-correlation function of the galaxies detected in each of the four IRAC instrument channels is consistent with a power-law form $w(θ)=Aθ^{1-γ}$ out to $θ= 0.2\arcdeg$, with the slope ranging from $γ= 1.5$ to 1.8. We estimate the correlation amplitudes $A$ to be $2.95 \times 10^{-3}$, $2.03 \times 10^{-3}$, $4.53 \times 10^{-3}$, and $2.34 \times 10^{-3}$ at $θ=1\arcdeg$ for galaxies detected in the IRAC 3.6$μ$m, 4.5$μ$m, 5.8$μ$m, and 8.0$μ$m instrument channels, respectively. We compare our measurements at 3.6$μ$m with the previous K-band measurements, and discuss the implications of these results.

Publisher: name: Zenodo
Year: 2012

description: A key objective of the International Household Survey Network is to provide data management tools to producers of microdata. These cover all phases of survey implementation, from survey design to data dissemination. Products include a suite of free, open source, DDI compliant data curation tools, known as the IHSN Microdata Management Toolkit. The IHSN Microdata Management Toolkit is being used in National Statistics Offices, the main data producers in developing countries, as well as increasingly by Universities and large International Development Agencies. This presentation will discuss the latest version of our data dissemination application, the National Data Archive as well as our future roadmap for this tool. We will also introduce our Question Bank and our new citations tool and central survey catalogue. Usage examples will include those at a large International Development Agency, a University and some National Statistics Offices.

description: We report on optical excitations in the magnetically ordered phases of multiferroic Fe$_{1.86}$Zn$_{0.14}$Mo$_3$O$_8$ in the frequency range from 10-130 cm$^{-1}$ (0.3-3.9 THz). In the collinear easy-axis antiferromagnetic phase below $T_N=50$~K eleven optically active modes have been observed in finite magnetic fields, assuming that the lowest-lying mode is doubly degenerate. The large number of modes reflects either a more complex magnetic structure than in pure Fe$_{2}$Mo$_3$O$_8$ or that spin stretching modes become active in addition to the usual spin precessional modes. Their magnetic field dependence, for fields applied along the easy axis, reflects the irreversible magnetic-field driven phase transition from the antiferromagnetic ground state to a ferrimagnetic state, while the number of modes remains unchanged in the covered frequency region. We determined selection rules for some of the AFM modes by investigating all polarization configurations and identified magnetic- and electric-dipole active modes as well. In addition to these sharp resonances, a broad electric-dipole active excitation band, which is not influenced by the external magnetic field, occurs below $T_N$ with an onset at 12 cm$^{-1}$. We are able to model this absorption band as a vibronic excitation related to the lowest-lying Fe$^{2+}$ electronic states in tetrahedral environment.

description: Let $G$ be a connected semisimple Lie group with a finite center, with a maximal compact subgroup $K$. There are two general methods to construct representations of $G$, namely, ordinary parabolic induction and cohomological parabolic induction. We define Eisenstein integrals relative to cohomological inductions which generalize Flensted-Jensen's fundamental functions for discrete series. They are analogous to Harish-Chandra's Eisenstein integrals related to ordinary inductions. We introduce the notion of Li positivity of a $K$ type in a representation of $G$ which is extremely useful in the study of branching laws. As an application of our integral, we show that the minimal $K$ types of many interesting representations are Li positive. These include all irreducible unitary representations with nonzero cohomology.

description: We summarize main mechanisms to realize the vector manifestation (VM), in which the massless vector meson becomes the chiral partner of pion, at the critical temperature in hot QCD within the framework of the model based on the hidden local symmetry. Then, we show a recent analysis on the direct photon-pi-pi coupling which measures the validity of the vector dominance (VD) of the electromagnetic form factor of the pion: The VM predicts that the VD is largely violated at the critical temperature.

VizLab: A Tool for the Interactive Exploration of Geospatial Election Data on the Web
Creators: name: Schaal, Adam
Publisher: name: Zenodo
Year: 2012

description: Advanced desktop tools for geospatial data management and visualization are nothing new. What are new are developments in advanced online tools which help bring some of the same functionalities to the web, and in doing so make the data more accessible to the masses. Each of these solutions has its strengths and its weaknesses- depending on the goals of the application. With a lack of complete solutions (particularly non-commercial ones), custom application development is sometimes needed to meet an institution's goals. Requiring an online visualization/exploration tool for its election and demographic data holdings, the CDSP has developed an application that provides certain features key to its research community. Unlike with most existing tools, the user is able to create custom variables from those already available. Further, users can analyze multiple variables simultaneously through a combination of choropleths, proportional circles, charts, and tables. Also supported is the analysis of geospatial data across changing administrative boundaries. Additionally, the user is able to save the online application state for later analysis, as well as for sharing with colleagues. The online application was developed using entirely free and open source tools.
Sensitivity of Polarization to Grain Shape: II. Aggregates

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: A previous study (Paper I) investigated the polarization properties of a variety of simple convex grain shapes, some of which were found to be consistent with the observed polarization properties of interstellar dust from far-ultraviolet to far-infrared. Here we study the optical properties of 45 non-convex shapes, all aggregates of $N$ equal-sized spheres. We consider $N=2$, $N=3$, and $N=256$ random aggregates obtained from 3 different aggregation schemes. We also consider "trimmed" $N=256$ aggregates obtained by systematically trimming initially random aggregates to increase either flattening or elongation. The "macroporosities" of the studied aggregates range from ${\cal P}_{\rm macro}=0.18$ (for the $N=2$ bisphere) to ${\cal P}_{\rm macro}\approx 0.85$ (for the $N=256$ "BA" aggregates). The only aggregates consistent with observations of starlight polarization and polarized thermal emission are shapes that have been trimmed to increase their asymmetry. If interstellar grains are high-porosity aggregates, there must be processes causing extreme elongation or flattening; if not, interstellar grains must be dominated by fairly compact structures, with at most moderate porosities. The ratio of polarization in the 10$μ$m silicate feature to starlight polarization in the optical is shown to be insensitive to porosity and shape. X-ray scattering may be the best tool to determine the porosity of interstellar grains. We propose that modest porosities of interstellar grains could be the result of "photolytic densification". High polarization fractions observed in some Class-0 cores require processes to reduce porosities and/or increase asymmetries of aggregates in dense regions.
