description: It was recently demonstrated that in La_{2-x}Sr_{x}CuO_{4} the magnetic-field (H) dependence of the low-temperature thermal conductivity κup to 16 T reflects whether the normal state is a metal or an insulator. We measure the H dependence of κin YBa_{2}Cu_{3}O_{y} (YBCO) at subkelvin temperatures for a wide doping range, and find that at low doping the κ(H) behavior signifies the change in the ground state in this system as well. Surprisingly, the critical doping is found to be located deeply inside the underdoped region, about the hole doping of 0.07 hole/Cu; this critical doping is apparently related to the stripe correlations as revealed by the in-plane resistivity anisotropy.

description: We present a systematic search for variability among the ROSAT All-Sky Survey (RASS) X-ray sources. We generated lightcurves for about 30000 X-ray point sources detected sufficiently high above background. For our variability study different search algorithms were developed in order to recognize flares, periods and trends, respectively. The variable X-ray sources were optically identified with counterparts in the SIMBAD, the USNO-A2.0 and NED data bases, but a significant part of the X-ray sources remains without cataloged optical counterparts. Out of the 1207 sources classified as variable 767 (63.5 %) were identified with stars, 118 (9.8 %) are of extragalactic origin, 10 (0.8 %) are identified with other sources and 312 (25.8 %) could not uniquely be identified with entries in optical catalogs. We give a statistical analysis of the variable X-ray population and present some outstanding examples of X-ray variability detected in the ROSAT all-sky survey. Most prominent among these sources are white dwarfs, apparently single, yet nevertheless showing periodic variability. Many flares from hitherto unrecognised flare stars have been detected as well as long term variability in the BL Lac 1E1757.7+7034.

description: Located in Hostomel, Ukraine, this project focuses on healing and renewing a site devastated by conflict. Drawing inspiration from the Ukrainian Antonov An-225 Mriya, the world’s largest aircraft ever built by the Soviet Union, the project repurposes the craters left by the aircraft’s destruction on February 24, 2022, at Antonov International Airport as symbols of resilience and hope. Employing ecological restoration measures, a series of strategies are used to transform the craters into features that celebrate life and renewal, while also honoring the past and looking towards the future. This innovative approach to monument-making is a testament to the transformative power of humanism, demonstrating how creativity and a sustainable mindset can contribute towards a more peaceful and harmonious world. Aiming to encourage others to work towards a better future, this project emphasizes the value of community, resilience, and hope in the face of tragedy. Through its creative vision and dedication to sustainability, it offers a powerful example of how we can find strength in adversity and rebuild in harmony with the environment.
The Central 300 pc of the Galaxy probed by infrared spectra of H$_3^+$ and CO: part I. Predominance of warm and diffuse gas and high H$_2$ ionization rate

description: The molecular gas in the Central Molecular Zone (CMZ) of the Galaxy has been studied using infrared absorption spectra of H$_3^+$ lines at 3.5-4.0 $μ$m and CO lines near 2.34 $μ$m. In addition to the previously reported spectra of these lines toward 8 stars located within 30 pc of Sgr A$^\ast$, there are now spectra toward $\sim$30 bright stars located from 140 pc west to 120 pc east of Sgr A$^\ast$. The spectra show the presence of warm ($T\sim 200$ K) and diffuse ($n < 100 $cm$^{-3}$) gas with $N$(H$_3^+$) $\sim 3 \times 10^{15} $cm$^{-2}$ on majority of sightlines. Instead of our previous analysis in which only electrons from photoionization of carbon atoms were considered, we have developed a simple model calculation in which the cosmic ray ionization of H$_2$ and H are also taken into account. We conclude: (1) Warm and diffuse gas dominates the volume of the CMZ. The volume filling factor of dense gas must be much less than 0.1 and the CMZ is not as opaque as previously considered. The X-ray emitting ultra-hot 10$^8 $K plasma, which some thought to dominate the CMZ, does not exist over extended regions. (2) The cosmic ray ionization rate is $ζ\sim 2 \times 10^{-14} $s$^{-1}$, higher than in Galactic dense clouds and diffuse clouds by factors of $\sim$1000 and $\sim$100, respectively. If the equipartition law stands, this suggests a pervading magnetic field on the order of $\sim$100 $μ$G.

description: A double source plane (DSP) system is a precious probe for the density profile of distant galaxies and cosmological parameters. However, these measurements could be affected by the surrounding environment of the lens galaxy. Thus, it is important to evaluate the cluster-scale mass for detailed mass modeling. We observed the {\it Eye of Horus}, a DSP system discovered by the Subaru HSC--SSP, with XMM--Newton. We detected two X-ray extended emissions, originating from two clusters, one centered at the {\it Eye of Horus}, and the other located $\sim100$ arcsec northeast to the {\it Eye of Horus}. We determined the dynamical mass assuming hydrostatic equilibrium, and evaluated their contributions to the lens mass interior of the Einstein radius. The contribution of the former cluster is $1.1^{+1.2}_{-0.5}\times10^{12}~M_{\odot}$, which is $21-76\%$ of the total mass within the Einstein radius. The discrepancy is likely due to the complex gravitational structure along the line of sight. On the other hand, the contribution of the latter cluster is only $\sim2\%$ on the {\it Eye of Horus}. Therefore, the influence associated with this cluster can be ignored.

Following the successful 2016 launch of the Big Ten Academic Alliance Geoportal (https://geo.btaa.org/), we now turn our attention to progressing into a sustainable growing project.This presentation will detail the Geoportal's content and interface and the collaboration structure of the project. Additionally, we will discuss a novel user study with results showing interesting differences between users of varied expertise, which fueled changes in the Geoportal interface. Attendees will be oriented to various considerations involved in establishing and maintaining an aggregation of geospatial information from diverse sources, including the access stability issues involved in data hosted by local governments, the generation of metadata for geospatial datasets and digitized maps, and project structure evolution. We hope our experiences will inspire others toward similar kinds of large-scale collaborative projects.

description: We give some classes of power maps with low $c$-differential uniformity over finite fields of odd characteristic, {for $c=-1$}. Moreover, we give a necessary and sufficient condition for a linearized polynomial to be a perfect $c$-nonlinear function and investigate conditions when perturbations of perfect $c$-nonlinear (or not) function via an arbitrary Boolean or $p$-ary function is perfect $c$-nonlinear. In the process, we obtain a class of polynomials that are perfect $c$-nonlinear for all $c\neq 1$, in every characteristic. The affine, extended affine and CCZ-equivalence is also looked at, as it relates to $c$-differential uniformity.

Year: 2024
Subjects: Data privacy, AI governance, Technology law, Innovation, Security

description: This paper examined the dual objectives of fostering innovation through AI while ensuring robust data privacy. The paper adopted the doctrinal method of research by relying on both primary and secondary sources of information or data. Primarily, it utilises a legal approach using data such as the European Union Artificial Intelligence Act, the General Data Protection Regulation, the California Consumer Protection Act and the Nigeria Data Protection Act. The secondary sources of data used include textbooks, online articles in learned journals, relevant materials from the internet, magazines, newspapers, other periodicals, dictionaries and reports. The study found that a multi-faceted approach is necessary to navigate the intersection of AI and data privacy, ensuring that technological progress does not compromise individual rights and trust in AI systems and finally make recommendations which include technical solutions such as differential privacy, federated learning, and homomorphic encryption which aim to balance data utility and privacy

description: As scanning tunneling microscopy is pushed towards fast local dynamics, a quantitative understanding of tunnel junctions under the influence of a fast AC driving signal is required, especially at the ultra-low temperatures relevant to spin dynamics and correlated electron states. We subject a superconductor-insulator-superconductor junction to a microwave signal from an antenna mounted \textit{in situ} and examine the DC response of the contact to this driving signal. Quasi-particle tunneling and the Josephson effect can be interpreted in the framework of Tien-Gordon theory. The situation is more complex when it comes to higher order effects such as multiple Andreev reflections. Microwave assisted tunneling unravel these complex processes, providing deeper insights into tunneling than are available in a pure DC measurement.

description: The Continuous Capture of Metadata Project (C²Metadata) aims to automate the process of describing and documenting research data that are managed and analyzed in leading statistical software packages (SPSS®, SAS®, Stata®, R). Statistics packages offer limited ways of describing data, and they provide little help in documenting data transformations and provenance. At best the operations performed by the statistical package are described in a script, which more often than not is unavailable to future data users. Even if DDI metadata exists, updating it to reflect changes made by a statistics package is a manual process. C²Metadata is creating tools that read scripts for the four main statistics packages and insert data transformation metadata into DDI files. We are creating a Standard Data Transformation Language (SDTL), which represents data transformations in a JSON format that is independent of the original statistics package. Our software will also render SDTL metadata into human-readable forms for inclusion in codebooks and other forms of documentation. This session will describe and demonstrate these new tools.

Year: 1976

description: The purpose of this study was to examine the effects of hypothesizing on concept learning. Such effects may depend upon task requirements. A 3 X 2 X 2 factorial design was used to assess the variables of time of hypothesizing (early in the task, late in the task, or no hypothesizing), rule type (conjunctive or conditional), and amount of information in the instructions (low amount as defined by a complete learning task or high amount as defined by an attribute identification task). The conjunctive rule was solved significantly more quickly than the conditional rule and attribute identification was solved significantly faster than complete learning, findings which concur with previous research. Interactions with the hypothesizing variable were not significant. The latter results were interpreted in terms of possible biasing effects of the experimental instructions.

description: Data ingest -- the process by which data and related materials are deposited with an archive -- is the crucial entry point upon which all subsequent curation, preservation, and dissemination activities rely. Ingest includes describing and transferring files, as well as obtaining legal permissions necessary to establish adequate legal and intellectual control over digital objects. This presentation discusses recent activities at ICPSR to optimize the data ingest process. By optimization, we mean making the process as easy and convenient for the depositor while gathering as much information about the data collection to enable reuse and preservation. Specific discussion points will include (1) a brief history of ICPSR's data ingest process; (2) a comparison of other archives' data ingest processes; (3) recent improvements and enhancements to the ICPSR data ingest process, including from a major update in June 2017; and (4) lessons learned from the June 2017 update.

description: One of the best tools we have in geophysical modelling is the ability to interpolate the horizontal geomagnetic field at the surface of the Earth. This is especially useful in regions, such as southern Africa, where there is a sparse array of absolute magnetometers available for geomagnetic field measurements. In terms of geomagnetic field interpolation, the spherical elementary current systems (SECS) spatial interpolation scheme has shown to be very successful, and the planar approximation of this method adequate for modelling at mid-latitudes. The SECS interpolation scheme is physics based, making use of the Biot-Savart law and equivalent ionospheric currents to interpolate measured geomagnetic field data. As with most interpolation methods, more data points result in lower error. Therefore, we adapt the SECS method to work with variometers. These instruments measure variations in magnetic field and are more abundant in southern Africa. Merging the two resulting interpolated datasets, the initial absolute geomagnetic field interpolation can be significantly improved. This improved interpolation scheme is not only incredibly useful locally, where a sparse magnetometer array is a challenge, but can also be applied just as effectively in other cases across the globe where there are numerous magnetometers and variometers available.

The main feature of this model is that it is a simple TeV scale model, a scale accessible in near future machines, with a minimal particle content. Both supersymmetric and non-supersymmetric versions of the model are feasible. This model also gives left-handed neutrino masses compatible with all current data from direct and indirect neutrino experiments.

description: The magnetic solitons such as chiral solitons, magnetic skyrmions, and magnetic hopfions, exhibiting particlelike nature widely emerge in magnets depending on spatial dimension. As their number directly gives rise to an impact on magnetic properties and electronic properties, it is of great importance to control the number of solitons. However, a systematic study on dynamical processes to control the number of solitons, particularly by adding the desired number of solitons to the ground state exhibiting periodic arrangements of solitons, has been limited thus far. Here, we theoretically perform the systematic analysis for the dynamical control of the number of chiral solitons in monoaxial chiral magnets by effectively utilizing the edge modes whose excitation is localized near the edges. By studying the dynamical process associated with this edge mode in an applied rotating magnetic field by using the Landau-Lifshitz-Gilbert equation, we show that multiple soliton penetrations can take place until the system reaches the nonequilibrium steady state, and the number of infiltrated solitons successively increases with the amplitude of the rotating magnetic field after surpassing the threshold. We also clarify that the threshold amplitude of the rotating magnetic field can be reduced through the static magnetic field. Our results reveal that the desired number of solitons can be added within a certain range by taking advantage of the edge modes that appear without any special processing at the edges of the system. These results contribute to the development of an experimental way to control the number of solitons and are expected to be further applied to a wide range of magnetic solitons, not limited to chiral solitons.

description: We present configuration-space estimators for the auto- and cross-covariance of two- and three-point correlation functions (2PCF and 3PCF) in general survey geometries. These are derived in the Gaussian limit (setting higher-order correlation functions to zero), but for arbitrary non-linear 2PCFs (which may be estimated from the survey itself), with a shot-noise rescaling parameter included to capture non-Gaussianity. We generalize previous approaches to include Legendre moments via a geometry-correction function calibrated from measured pair and triple counts. Making use of importance sampling and random particle catalogs, we can estimate model covariances in fractions of the time required to do so with mocks, obtaining estimates with negligible sampling noise in $\sim 10$ ($\sim 100$) CPU-hours for the 2PCF (3PCF) auto-covariance. We compare results to sample covariances from a suite of BOSS DR12 mocks and find the matrices to be in good agreement, assuming a shot-noise rescaling parameter of $1.03$ ($1.20$) for the 2PCF (3PCF). To obtain strongest constraints on cosmological parameters we must use multiple statistics in concert; having robust methods to measure their covariances at low computational cost is thus of great relevance to upcoming surveys.

description: In the area of the empirical social sciences, research data have always played a major role for advancing knowledge. However, expectations regarding availability of data for research have increased tremendously over the past years. At the same time, higher complexity of datasets and more diverse origins of data lead to even more demanding challenges. In response to those challenges a great number of services were developed to support researchers with the task of research data management. Examples at GESIS -- Leibniz-Institute for the Social Sciences Data Archive for the Social Sciences are da|ra (DOI registration agency), datorium (data repository service), and SowiDataNet (comprehensive research data infrastructure). The latter supports institutional data management in research organizations already in an early stage of empirical projects. The presentation will show the current state of affairs with the implemented SowiDataNet service and the interplay between the tools. Special consideration will be given to data curation workflows, the roles of data depositors -- institutional or individual -- and curators. In addition, the presentation will focus on the functionalities provided by SowiDataNet, e.g. checklists for basic and more advanced workflow steps, versioning of data and documentation, and assignment of persistent identifiers (DOIs). Finally, future developments towards an integration of different services will be presented.

description: In the framework of the topcolor-assisted technicolor (TC2) models, we study the production of the top-pions $π^{0}_{t}$, $π_{t}^{\pm}$ via the processes $ep\toγc\toπ^{0}_{t}c$ and $ep\toγc\toπ^{\pm}_{t}b$ mediated by the anomalous top coupling $tcγ$. We find that the production cross section of the process $ep\toγc\toπ^{0}_{t}c$ is very small. With reasonable values of the parameters in TC2 models, the production cross section of the process $ep\toγc\toπ^{\pm}_{t}b$ can reach $ 1.2pb$. The charged top-pions $π^{\pm}_{t}$ might be directly observed via this process at the THERA collider based $γp$ collisions.

description: Most of the major planets in the Solar System support populations of co-orbiting bodies, known as Trojans, at their L4 and L5 Lagrange points. In contrast, Earth has only one known co-orbiting companion. This paper presents the results from a search for Earth Trojans using the DECam instrument on the Blanco Telescope at CTIO. This search found no additional Trojans in spite of greater coverage compared to previous surveys of the L5 point. Therefore, the main result of this work is to place the most stringent constraints to date on the population of Earth Trojans. These constraints depend on assumptions regarding the underlying population properties, especially the slope of the magnitude distribution (which in turn depends on the size and albedo distributions of the objects). For standard assumptions, we calculate upper limits to a 90% confidence limit on the L5 population of $N_{ET}<1$ for magnitude $H<15.5$, $N_{ET}=60-85$ for $H<19.7$, and $N_{ET}\ $= 97 for $H=20.4$. This latter magnitude limit corresponds to Trojans $\sim$300 m in size for albedo $0.15$. At H=19.7, these upper limits are consistent with previous L4 Earth Trojan constraints and significantly improve L5 constraints.

description: We study the expected volume of random polytopes generated by taking the convex hull of independent identically distributed points from a given distribution. We show that for log-concave distributions supported on convex bodies, we need at least exponentially many (in dimension) samples for the expected volume to be significant and that super-exponentially many samples suffice for concave measures when their parameter of concavity is positive.

description: The objectives of this study were to extract and purify Bixin from the seeds of Bixa orellana and to evaluate its hypoglycemic activity in vivo, as well as, to conduct an in silico study of selectivity on peroxisome proliferator-activated receptors via molecular docking and molecular dynamics simulations. Oral administration of Bixin (10mg/kg) significantly reduced their glucose level that was alloxan-induced diabetic rats. Bixin showed in silico selectivity on peroxisome proliferator-activated receptors (PPARs), particularly by the peroxisome proliferator-activated receptor gamma (PPARγ), which supports the hypoglycemic activity of Bixin. From the results obtained, it can be inferred that Bixin presents hypoglycemic characteristics, which was confirmed by the results obtained from the in vivo and in silico tests. Bixin may act by other pathways to control blood glucose and thus it is possible that it presents a different toxicity profile than troglitazone, rosiglitazone and pioglitazone. However, more studies on the activity and toxicity of Bixin are needed to evaluate for further clinical use.

description: The high frequency peaked blazar PKS 2155-304 is one of the brightest and most intensively studied prototype of BL Lac objects. Gamma-rays from PKS 2155-304 have been detected from the MeV to TeV ranges. We computed a synchrotron self-Compton (SSC) model, based on the temporal behavior of the particles distribution, responsible for the high-energy emission. Using the available simultaneous multiwavelength data, we simulated the overall spectral energy distribution (SED) and the spectral variability of this source.

FORSbase: Implementing the fair principles for social science data archives
Creators: name: Buerli, Stefan
Publisher: name: Zenodo
Year: 2018

description: For a social science data archive, Open Science in the strict sense is a generally a no-go for obvious data protection reasons. However, the FAIR principles can be implemented while at the same time satisfying the data producer, the data user, and data protection laws. In order to reach that objective, FORS -- the Swiss Centre for Expertise in the Social Sciences -- developed FORSbase, an online web application that makes data discovery, deposit, and delivery as convenient and as open as possible for data in the social sciences. Its goal is to combine within a single system and database a wide range of archiving functions and tools for researchers themselves to document and deposit their data, to choose between different degrees of openness regarding delivery, to access data and metadata, and to establish contacts and communicate with other researchers. In sum, for the social sciences appropriate infrastructure is needed to mediate the specific needs of data producers and users in relation to FAIR principles and data protection laws. FORSbase provides just such a technical solution, facilitating the sharing and use of secondary data, while at the same time protecting the confidentiality of research participants.

description: We present some recent theory and simulation results addressing the phenomena of colloidal gelation at both high and low volume fractions, in the presence of short-range attractive interactions. We discuss the ability of mode-coupling theory and its adaptations to address situations with strong heterogeneity in density and/or dynamics. We include a discussion of the effect of attractions on the shear-thinning and yield behaviour under flow.

Ruin[ed] : adjective /ˈro͞oˌind/ : reduced to a state of decay, collapse, or disintegration : having been irreparably damaged or harmed.
Creators: name: Brekelmans, Nicole
Publisher: name: The University of British Columbia
Year: 2023

description: The Anthropocene can be defined by many things, but within this project it is defined as “The age of ruins” – degradation of communities from both social and ecological disasters, many of which were never reconciled and hidden under the layers of the landscape. Ruin[ed] explores landscape architecture as storytelling through the process of disaster repair – allowing memories both painful and hopeful to be embedded into the land and for reflection and healing to take place. Situated within the aftermath of the “Big One” at UBC the project engages with two disasters – the earthquake itself, and the disaster of UBC’s ongoing harm of developing on and profiting from stolen land, exploiting resources, and destroying habitat. Thrusted into this state of transformation out of human’s control, as a collective we will begin to ask what is ruined, what has been ruined in the past, and how can we begin to reconcile such anthropogenic and institutional ruins through ongoing acts of care and repair?

description: 2D materials offer an ideal platform to study the strain fields induced by individual atomic defects, yet challenges associated with radiation damage have so-far limited electron microscopy methods to probe these atomic-scale strain fields. Here, we demonstrate an approach to probe single-atom defects with sub-picometer precision in a monolayer 2D transition metal dichalcogenide, WSe$_{2-2x}$Te$_{2x}$. We utilize deep learning to mine large datasets of aberration-corrected scanning transmission electron microscopy images to locate and classify point defects. By combining hundreds of images of nominally identical defects, we generate high signal-to-noise class-averages which allow us to measure 2D atomic coordinates with up to 0.3 pm precision. Our methods reveal that Se vacancies introduce complex, oscillating strain fields in the WSe$_{2-2x}$Te$_{2x}$ lattice which cannot be explained by continuum elastic theory. These results indicate the potential impact of computer vision for the development of high-precision electron microscopy methods for beam-sensitive materials.

Caring for sharing: Improving self-deposit repository publishing systems
Creators: name: Vlad, Anca Daniela
Publisher: name: Zenodo
Year: 2018

description: ReShare is the self-deposit data repository of the UK Data Service, now in its third year and holding some 1,200 collections of data, spanning a wide disciplinary range of research assets. It has become the primary publishing system for social science research data in the United Kingdom, and over time has sought to continuously improve its publishing process. Areas of focus have been on enabling an easy-to-use interface and an intuitive workflow, and adding useful metrics for us as data publishers. The tool itself has also been an excellent opportunity to raise awareness of creating high quality sharable data, fulfilling our mission to support and train researchers in good data management practices. The presentation will walk through the main features of ReShare and what has been improved, provide an overview of data collections ingested, and speak to possible future improvements. Finally, it will demonstrate the tracking metrics collected via Google Analytics on active users, sessions, locations and devices being used, as well as a segment on broader ReShare metrics, showing compliance with the COUNTER Code of Practice for metrics

description: This paper describes the characterization of a new infectious bronchitis virus (IBV) strain D181, that rapidly evolved from a low-level incidental finding in 2017 to become the second most isolated IBV strain in Dutch layers and breeders in 2018, as well as being found in samples from Germany and Belgium. Based on the sequence of the S gene and the results of cross-neutralization tests, D181 can be considered as a new serotype and the second lineage within genotype II (GII-2). The experimental infection of SPF hens confirmed the ability of D181 to cause a drop in egg production, and immunohistochemistry showed presence of the virus in the trachea, lung and conjunctiva at 5 days post inoculation and in the caecal tonsils at 5 and 8 days post inoculation. In silico analysis of several widely used PCR primers indicated that primer sets adapted for GII might be needed to detect D181, as many general S1 primers might miss it.
