Under Lock and Key? Setting up a Secure Data Center at GESIS in Germany
Creators: name: Kinder-Kurlanda, Katharina
name: Eder, Christina
Publisher: name: Zenodo
Year: 2013

description: This poster is about the specific challenges in setting up a secure data service at GESIS – Leibniz Institute for the Social Sciences. German data protection law (Bundesdatenschutzgesetz) gives every person the right to protection of their personal data. The re-use of survey data, for example, must be provided in a way that no individual person is identifiable. This usually means that data is anonymized. However, anonymization is often difficult to achieve without compromising the quality of the data. To enable research access to disclosive data, GESIS – Leibniz Institute for the Social Sciences is establishing a secure data center with three controlled access points: A low-level solution employing a comprehensive legal contract, a safe room providing particularly strict access control, and, a remote access system. Using German electoral survey data as a practical example, we will examine the technical and organizational challenges, opportunities and questions that arise when building a secure data service in the context of the German data protection framework, which comprises both federal and state laws. We introduce our strategy of setting up pilots for the usage models. This strategy enables us to better understand the legal framework and GESIS's role within it, and also to improve the service's usability by integrating test users' feedback.

description: EUMETSAT is currently developing the on-ground processing chain of the infrared Fourier transform spectrometers (IRS) on-board of the Meteosat Third Generation sounding satellites (MTG-S). In this context, the authors have investigated the impact of a particular type of radiometric error, called hereafter the calibration ringing. It arises in Fourier transform spectrometers when the instrument Radiometric Transfer Function (RTF) varies within the domain of the instrument Spectral Response Function (SRF). The expected radiometric errors are simulated in the context of the MTG-S IRS instrument in the long wave infrared (LWIR) band. Making use of a principal components (PC) decomposition, a software correction, called RTF uniformisation, is designed and its performance is assessed in the context of MTG-S IRS.

Higgs boson to $γZ$ decay as a probe of flavour changing neutral Yukawa couplings

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

description: With the deeper study of Higgs particle, Higgs precision measurements can be served to probe new physics indirectly. In many new physics models, vector-like quarks $T_L,~T_R$ occur naturally. It is important to probe their couplings with standard model particles. In this work, we consider the singlet $T_L,~T_R$ extended models and show how to constrain the $Tth$ couplings through the $h\rightarrowγZ$ decay at high-luminosity LHC. Firstly, we derive the perturbative unitarity bounds on $|y_{L,~R}^{tT}|$ with other couplings set to be zeros simply. To optimize the situation, we take $m_T$ = 400 GeV and $s_L$ = 0.2 considering the experimental constraints. Under this benchmark point, we find that the future bounds from $h\rightarrowγZ$ decay can limit the real parts of $y_{L,~R}^{tT}$ in the positive direction to be O(1) because of the double enhancement. For the real parts of $y_{L,~R}^{tT}$ in the negative direction, it is always surpassed by the perturbative unitarity. Moreover, we find that the top quark electric dipole moment can give stronger bounds (especially the imaginary parts of $y_{L,~R}^{tT}$) than the perturbative unitarity and $h\rightarrowγZ$ decay in the off-axis regions for some scenarios.

description: Energy transfers in collisions between classical clusters are studied with Classical N Body Dynamics calculations for different entrance channels. It is shown that the energy per particle transferred to thermalised classical clusters does not exceed the energy of the least bound particle in the cluster in its ``ground state''. This limitation is observed during the whole time of the collision, except for the heaviest system.

description: This work presents the first comprehensive study of structure formation at the peak epoch of cosmic star formation over $1.4\leq z \leq 3.6$ in the COSMOS field, including the most massive high redshift galaxy proto-clusters at that era. We apply the extended COSMIC BIRTH algorithm to account for a multi-tracer and multi-survey Bayesian analysis at Lagrangian initial cosmic times. Combining the data of five different spectroscopic redshift surveys (zCOSMOS-deep, VUDS, MOSDEF, ZFIRE, and FMOS-COSMOS), we show that the corresponding unbiased primordial density fields can be inferred, if a proper survey completeness computation from the parent photometric catalogs, and a precise treatment of the non-linear and non-local evolution on the light-cone is taken into account, including (i) gravitational matter displacements, (ii) peculiar velocities, and (iii) galaxy bias. The reconstructions reveal a holistic view on the known proto-clusters in the COSMOS field and the growth of the cosmic web towards lower redshifts. The inferred distant dark matter density fields concurrently with other probes like tomographic reconstructions of the intergalactic medium will explore the interplay of gas and dark matter and are ideally suited to study structure formation at high redshifts in the light of upcoming deep surveys.

description: This paper proposes an extension of generalized autoregressive conditional heteroskedasticity (GARCH) models for a time series to those for spatial data, which are called here spatial GARCH (S-GARCH) models. S-GARCH models are re-expressed as spatial autoregressive moving-average (SARMA) models and a two-step procedure based on quasi-likelihood functions is proposed to estimate the parameters. The consistency and asymptotic normality are proven for the two-step estimators. S-GARCH models are applied to simulated and land-price data in areas of Tokyo to demonstrate the empirical properties.
Focusing Services and Expertise: The Research Data Centre International Survey Programs at GESIS-Leibniz Institure for the Social Sciences

description: The poster will showcase diverse added-value services provided by the GESIS RDC International Survey Programs as a central access point for cross-national and cross-cultural survey databases with a wide thematic scope of attitudinal data and subjective social indicators, encompassing an ever-expanding number of countries across several decades. The RDC International Survey Programs was established in order to focus the institution's expertise and activities in this field, benefiting from prominent involvement in almost all steps of the research data life cycle: from the standard demography development for the ISSP or the multilingual instrument documentation and development in the EVS, over data harmonization and detailed documentation in close cooperation with the principal investigators (CSES, EVS, ISSP) to online access facilities to individual level datasets and related materials, even across distributed platforms where necessary (European Elections Study). To complement the infrastructure components, the analysis potential of the comparative database will be exemplified in research oriented data reports and workshops. The poster will also point to future potentials such as the strengthening of links between comparative survey programs and other data types for multi-level analysis.

description: Standardization and harmonization efforts have reached a consensus towards using a special-purpose Vehicular Public-Key Infrastructure (VPKI) in upcoming Vehicular Communication (VC) systems. However, there are still several technical challenges with no conclusive answers; one such an important yet open challenge is the acquisition of short-term credentials, pseudonym: how should each vehicle interact with the VPKI, e.g., how frequently and for how long? Should each vehicle itself determine the pseudonym lifetime? Answering these questions is far from trivial. Each choice can affect both the user privacy and the system performance and possibly, as a result, its security. In this paper, we make a novel systematic effort to address this multifaceted question. We craft three generally applicable policies and experimentally evaluate the VPKI system performance, leveraging two large-scale mobility datasets. We consider the most promising, in terms of efficiency, pseudonym acquisition policies; we find that within this class of policies, the most promising policy in terms of privacy protection can be supported with moderate overhead. Moreover, in all cases, this work is the first to provide tangible evidence that the state-of-the-art VPKI can serve sizable areas or domain with modest computing resources.

Lightly doped dimerized spin chain in the one-dimensional t-J-J' model

description: We study the one-dimensional t-J-J'-model in the limit of small hole doping $x$ and small $J/t$, $J'/t$. Special emphasis is put on the regime $J'/J \approx .5$ where a spin gap is present at small doping and the undoped spin chain is strongly dimerized. Using a perturbative approach and Luttinger liquid arguments, we demonstrate for this non-integrable class of models that the charge degrees of freedom behave as non-interacting spinless solitons in the dilute hole limit. Our approach is also used to evaluate the energy and mass renormalization of a single hole. Interestingly, the corrections of these quantities are in powers of $\sqrt{J/t}$. At $J'/J=.5$ we construct a variational spin-polaron wave function for the hole and find good agreement with our perturbative results.

Come in and Find out about Research Data: Documenting and Searching for Data in the German Data Reference System
Creators: name: Kratz, Sophia
Publisher: name: Zenodo
Year: 2013

description: Social science research data is produced by various institutions and projects. Although archives enable access to some data in well-established ways, many datasets which could be interesting for other researchers cannot be found because there is no central platform where datasets - archived or not - can be documented. As a consequence, there is no easy way for data creators to showcase the data they have collected. Similarly, it is very difficult for users to find the datasets best fitting their research. The existing information is highly scattered in a dispersed data landscape and cannot be found without further knowledge about institutions and projects. To solve these problems, GESIS - Leibniz Institute for the Social Sciences has started a project to identify and document data sources in Germany, which are currently not documented and made available in a systematic way. This database will also be open for researchers to describe their own data by using a tailored metadata schema and to search for already existing data available for secondary analysis. The aim of the poster is to present the current approach to building the data reference system, its position within the data services of GESIS, as well as its structure and features.

description: The study explores the geographical pattern of the accommodation industry in the Italian insular region of Sicily, focusing on the determinants of the risk of market exit. We adopt a standard framework of business survival analysis where agglomeration economies play an important role. We then extend the analysis by considering the role of geography to explore whether the risk of market exit depends on nearness to desirable amenities. The geography is here measured by the distance from the coast and the altitude of the place where the firm is located. When we look at the entire population of accommodation firms that started between 2010 and 2014, we find evidence that the risk of failure increases for those which are over 2 km from the coast.

description: Carbon and oxygen isotopic ratios are reported for a sample of 51 SRb- and Lb-type variable asymptotic giant branch stars. Vibration-rotation first- and second-overtone CO lines in 1.5-2.5 mum spectra were measured to derive isotopic ratios for 12C/13C, 16O/17O, and 16O/18O. Comparisons with previous measurements for individual stars and with various samples of evolved stars, as available in the extant literature, are discussed. Using the oxygen isotopic ratios, the masses of the SRb stars can be derived. Combining the masses with Gaia luminosities, the SRb stars are shown to be antecedents of the Mira variables. The limiting parameters where plane-parallel, hydrostatic equilibrium model atmospheres can be used for abundance analysis of M giants are explored.

description: We analytically investigate a 1d branching-coalescing model with reflecting boundaries in a canonical ensemble where the total number of particles on the chain is conserved. Exact analytical calculations show that the model has two different phases which are separated by a second-order phase transition. The thermodynamic behavior of the canonical partition function of the model has been calculated exactly in each phase. Density profiles of particles have also been obtained explicitly. It is shown that the exponential part of the density profiles decay on three different length scales which depend on total density of particles.

Let’s go outside : exploring the ways in which students use a newly re-wilded school ground to understand and experience nature
Creators: name: Thiessen, Dayle
Publisher: name: The University of British Columbia
Year: 2023

description: This is a report of a graduating project that involved a qualitative action-based research inquiry where children take on the role of co-researchers. It explores the ways in which we (students and teacher) used a newly re-wilded school ground to understand and experience nature. Throughout the school year, the nature-based inquiries conducted by students were documented in teacher journals, student artwork, student writings, and nature photographs. The Photovoice method was modified to develop a sense of wonder about the natural world. Situated in the research literature of ecology, eco-literacy, nature and place-based learning, it tells the story of taking students outside on a regular basis to reconnect with their home, the natural world. It is an example of how home economics can be integrated at the elementary level of schooling.

description: Non-Hermitian systems offer significant advantages in sensor design, especially at the exceptional points. However, the extreme sensitivity near these points poses great challenges due to fabrication errors and system noises, which degrade sensing performance. To address this, we introduce a novel approach leveraging the polarization degrees of freedom in non-Hermitian systems. In this work, we establish a direct relation between the incident polarization and the transmission phase of a coupled metasurface system and achieve the polarization-controlled phase singularity even post-fabrication. The incident polarization angle can be utilized as a sensing index, which enables indirect and accurate measurement. The theoretical approach is experimentally validated using a general design of THz non-Hermitian metasurface sensors. Our method enhances robustness and sensitivity, opening new avenues for practical applications in ultra-sensitive sensing.

This report provides the first direct measurement of the rate of this reaction using a radioactive 21Na beam, and discusses its astrophysical implications. The energy of the important state was measured to be E$_{c.m.}$= 205.7 $\pm$ 0.5 keV with a resonance strength $ωγ= 1.03\pm0.16_{stat}\pm0.14_{sys}$ meV.

description: To assess the quality of a probabilistic prediction for stochastic dynamical systems (SDSs), scoring rules assign a numerical score based on the predictive distribution and the measured state. In this paper, we propose an $ε$-logarithm score that generalizes the celebrated logarithm score by considering a neighborhood with radius $ε$. We characterize the probabilistic predictability of an SDS by optimizing the expected score over the space of probability measures. We show how the probabilistic predictability is quantitatively determined by the neighborhood radius, the differential entropies of process noises, and the system dimension. Given any predictor, we provide approximations for the expected score with an error of scale $\mathcal{O}(ε)$. In addition to the expected score, we also analyze the asymptotic behaviors of the score on individual trajectories. Specifically, we prove that the score on a trajectory can converge to the expected score when the process noises are independent and identically distributed. Moreover, the convergence speed against the trajectory length $T$ is of scale $\mathcal{O}(T^{-\frac{1}{2}})$ in the sense of probability. Finally, numerical examples are given to elaborate the results.

description: The cluster abundance and its redshift evolution are known to be a powerful tool to constrain the amplitude of mass fluctuations σ_8 and the mass density parameter Ω_m0. We study the impact of the finite decay rate of cold dark matter particles on the cluster abundances. On the basis of spherical model in decaying cold dark matter universe, we calculate the mass function of clusters and compare it with observed cluster abundance. We find the decay of cold dark matter particles significantly changes the evolution of the cluster abundance. In particular, we point out that the lifetime of dark matter particles comparable to the age of the universe lowers the ratio of the local cluster abundance to the high-redshift cluster abundance and can account for the observed evolution of the cluster abundance quite well. The strong dependence of the cluster abundance on the decay rate of dark matter suggests that distant cluster surveys may offer clues to the nature of dark matter.

description: For future nanoelectronic devices - such as room-temperature single electron transistors - the site-controlled formation of single Si nanocrystals (NCs) is a crucial prerequisite. Here, we report an approach to fabricate single Si NCs via medium-energy Si+ or Ne+ ion beam mixing of Si into a buried SiO2 layer followed by thermally activated phase separation. Binary collision approximation and kinetic Monte Carlo methods are conducted to gain atomistic insight into the influence of relevant experimental parameters on the Si NC formation process. Energy-filtered transmission electron microscopy is performed to obtain quantitative values on the Si NC size and distribution in dependence of the layer stack geometry, ion fluence and thermal budget. Employing a focused Ne+ beam from a helium ion microscope, we demonstrate site-controlled self-assembly of single Si NCs. Line irradiation with a fluence of 3000 Ne+/nm2 and a line width of 4 nm leads to the formation of a chain of Si NCs, and a single NC with 2.2 nm diameter is subsequently isolated and visualized in a few nanometer thin lamella prepared by a focused ion beam (FIB). The Si NC is centered between the SiO2 layers and perpendicular to the incident Ne+ beam.

description: Dark matter can capture in neutron stars from scattering off ultra-relativistic electrons. We present a method to calculate the capture rate on degenerate targets with ultra-relativistic momenta in a compact astronomical object. Our treatment accounts for the target momentum and the Fermi degeneracy of the system. We derive scaling relations for scattering with relativistic targets and confirm consistency with the non-relativistic limit and Lorentz invariance. The potential observation of kinetic heating of neutron stars has a larger discovery reach for dark matter-lepton interactions than conventional terrestrial direct detection experiments. We map this reach onto a set of bosonic and fermionic effective contact interactions between dark matter and leptons as well as nucleons. We show the results for the contact operators up to dimension 6 for spin-0 and spin-1/2 dark matter interactions with relativistic as well as non-relativistic Standard Model fermions. Highlights of this program in the case of vector mediated interactions are presented in a companion letter [1]. Our method is generalizable to dark matter scattering in any degenerate medium where the Pauli exclusion principle leads to relativistic targets with a constrained phase space for scattering.

description: We study multi-charged rotating string states on Type IIB regular backgrounds dual to confining SU(N) gauge theories with (softly broken) {\cal N}=1 supersymmetry, in the infra red regime. After exhibiting the classical energy/charge relations for the folded and circular two-charge strings, we compute in the latter case the one loop sigma-model quantum correction. The classical relation has an expansion in positive powers of the analogous of the BMN effective coupling, while the quantum corrections are non perturbative in nature and are not subleading in the limit of infinite charge. We comment about the dual field theory multi-charged hadrons and the implications of our computation for the AdS/{\cal N}=4 duality.

Stellar Active Latitudes from Seismic Travel Times
Creators: name: Kashyap, Samarth Ganesh
Publisher: name: Zenodo
Year: 2024

description: The eleven-year solar magnetic activity cycle is known to affect solar acoustic oscillations; higher activity is correlated with an increase in mode frequencies and a decrease in their lifetimes. Activity related frequency shifts have also been observed in other stars, but are difficult to measure mode by mode. Measuring activity induced changes to seismic mode travel times is an alternate method for activity studies and has been shown to be robust to noise. In this work we use a simple forward model to interpret such measurements for the Sun [1] in terms of magnetic activity versus time and latitude. We derive kernels that capture the sensitivity of travel-time measurement to surface activity to different latitudes. We perform linear inversions for the active latitudes using synthetic data and solar data using a regularized least squares technique. We demonstrate the applicability of this method to infer stellar butterfly diagrams.

description: The DDI Discovery Vocabulary represents the most important parts of DDI-Codebook and DDI-Lifecycle in the Web of Data covering the discovery use case. In various software projects in the statistical domain these elementary concepts are re-used to a large extent. Utilizing the DDI Discovery Vocabulary as the core data model the idea is to create a reusable data model, which can be extended and adjusted to the requirements of an individual project. In this poster, it is shown how the abstract data model can be implemented and how individual software products might leverage this model as a foundation for their own data models. By means of the MISSY use case, it is shown how a well-structured software architecture, based on the model-view-controller software design pattern, might look like, how certain software project layers interact, and how to implement different persistence formats like DDI-XML, DDI-RDF, and relational databases. This poster also will give a step-by-step guidance into how a project, which uses the DDI Discovery Vocabulary as an exchange format and core data model, can be build up from scratch. We will also show a live demonstration of the next generation of the Microdata Information System.

description: We present x-ray reflectivity measurements from the free surface of a liquid gallium-bismuth alloy (Ga-Bi) in the temperature range close to the bulk monotectic temperature $T_{mono} = 222$C. Our measurements indicate a continuous formation of a thick wetting film at the free surface of the binary system driven by the first order transition in the bulk at the monotectic point. We show that the behavior observed is that of a complete wetting at a tetra point of solid-liquid-liquid-vapor coexistance.

description: Electromagnetic relays and solenoid actuators are commonly used for their bistable behavior, which allows for switching between two states in electrical, pneumatic, or hydraulic circuits, among other applications. Although there has been extensive research on modeling, estimation, and control of these electromechanical systems, a gap remains in the analysis area. This paper addresses this gap by presenting an equilibrium and stability analysis to gain deeper insight into their bistability. This analysis leverages a hybrid dynamical model to obtain analytical expressions that relate the physical parameters to the switching conditions. These expressions are useful, e.g., for fundamental understanding, quick analyses, or design optimization. The results are discussed in depth and potential practical applications are explored. Finally, the analysis is validated with experimental results from a real device.

description: The fractal properties of four-dimensional Euclidean simplicial manifold generated by the dynamical triangulation are analyzed on the geodesic distance D between two vertices instead of the usual scale between two simplices. In order to make more unambiguous measurement of the fractal dimension, we employ a different approach from usual, by measuring the box-counting dimension which is computed by counting the number of spheres with the radius D within the manifold. The numerical result is consistent to the result of the random walk model in the branched polymer region. We also measure the box-counting dimension of the manifold with additional matter fields. Numerical results suggest that the fractal dimension takes value of slightly more than 4 near the critical point. Furthermore, we analyze the correlation functions as functions of the geodesic distance. Numerically, it is suggested that the fractal structure of four-dimensional simplicial manifold can be properly analyzed in terms of the distance between two vertices. Moreover, we show that the behavior of the correlation length regards the phase structure of 4D simplicial manifold.

description: The impact of unocculted stellar surface heterogeneities in the form of cool spots and hot faculae on the spectrum of a transiting planet has been a daunting problem for the characterization of exoplanet atmospheres. The wavelength-dependent nature of stellar surface heterogeneities imprinting their signatures on planetary transmission spectra are of concern particularly for systems of sub-Neptunes orbiting M-dwarfs. Here we present a systematic exploration of the impact of this spot-contamination on simulated near infrared transmission spectra of sub-Neptune planets. From our analysis, we find that improper correction of stellar surface heterogeneities on transmission spectra can lead to significant bias when inferring planetary atmospheric properties. However, this bias is negligible for lower fractions of heterogeneities (<1%). Additionally, we find that acquiring a priori knowledge of stellar heterogeneities does not improve precision in constraining planetary parameters if the heterogeneities are appropriately marginalized within a retrieval---however these are conditional on our confidence of stellar atmospheric models being accurate representations of the true photosphere. In sum, to acquire unbiased constraints when characterizing planetary atmospheres with the James Webb Space Telescope, we recommend performing joint retrievals of both the disk-integrated spectrum of the star and the stellar contamination corrected transmission spectrum.

description: We discuss the model consisting of tachyon which may have the negative kinetic energy plus scalar phantom and plus conformal quantum matter. It is demonstrated that such a model naturally admits two deSitter phases where the early universe inflation is produced by quantum effects and the late time accelerating universe is caused by phantom/tachyon. The energy conditions bounds for such cosmology are derived. It is interesting that effective equation of state may change its sign which depends from the proper choice of the combination of phantom/tachyon and quantum effects.

description: Finding and using relations between digital information systems and their respective data sources is a major issue in the area of scientific information management. A use-case in the social sciences is the linking of publications and underlying research data and making the link information directly accessible via integrated information systems. We present an architecture that allows integrating metadata on study research datasets from the public information system da|ra with metadata on literature from the Sowiport portal. The relations are extracted from study metadata and publication full texts using link detection algorithms developed in the InFoLiS project. By this, we show how to extend existing information systems to allow users to navigate between different datasets via relations.
