imputation

description: The Current Population Survey (CPS) is the nation's primary source of information on labor force participation and is typically used to generate national- and state-level estimates for a wide variety of indicators. Scientists are increasingly interested in linking contextual data measured over finer-grained geographies to the CPS. Geographic units such as metropolitan areas, cities, and counties are identified in the CPS, but a close examination reveals counties with large populations absent from the data while counties with smaller populations in the same metropolitan area are identified. We describe the process used to assign geographic identifiers to respondents and how that process leads to counties with large population being left off. We also describe strategies to recover or assign county identifiers for respondents who are missing them. These strategies consider the complex spatial relationships among metropolitan areas, cities, and counties.

description: We consider theoretically the interplay between Zeeman coupling and exchange-induced swap action in spin-based quantum dot quantum computer models in the presence of inhomogeneous magnetic fields, which are invariably present in real systems. We estimate quantitatively swap errors caused by the inhomogeneous field, establishing that error correction would, in principle, be possible in the presence of non-uniform magnetic fields in realistic structures.

description: The Current Population Survey (CPS) is the primary source for U.S. labor force data. In addition to its monthly coverage of demographic and employment information, the CPS contains occasional supplemental data on various topics including participation in and engagement with the arts. IPUMS CPS offers the Public Participation in the Arts and the Annual Arts Benchmarking surveys together under the name “Public Arts.” In this paper, we describe the challenges in weighting the CPS Public Participation in the Arts samples due to a complex survey design that varies across years, discuss our strategy for taking differences in weighting schemes into account when harmonizing Public Participation in the Arts and Annual Arts Benchmarking data, and provide guidance for researchers to tailor IPUMS CPS Public Arts supplement weights to their specific needs when necessary.

description: This white paper, published by Springer Nature, proposes and discusses key ways to improve on research data sharing practices. The related infographic is available in figshare: https://doi.org/10.6084/m9.figshare.7937195.v1
The report builds on previous white papers on research data sharing, summarising the findings and data from large-scale surveys into researcher views and behaviours. The findings are summarised as five essential factors on what needs to be done to make good research data practice common and widespread. This includes an analysis of the currently data policy landscape and impacts, researcher motivations for sharing data and practical solutions to making data more FAIR.
Specifically, this follows up with research conducted in China and Japan to complement the existing outputs based in North America and Europe. The report also summarises evidence from external sources on the impact of, and need for, data sharing.
All reports and summary data are openly available in the figshare repository from the links below. Data were collected in online surveys run between 2017-2019 and are stored in Excel spreadsheet format. Individual surveys vary slightly in methodology, with respondents self-selecting to an extent. See individual datasets for more detail.
Additional data supporting the findings of this report (for example the 2016 Nature online survey on reproducibility) are linked under References.

description: Identifying the magnetic state of materials is of great interest in a wide range of applications, but direct identification is not always straightforward due to limitations in neutron scattering experiments. In this work, we present a machine-learning approach using decision-tree algorithms to identify magnetism from the spin-integrated excitation spectrum, such as the density of states. The dataset was generated by Hartree-Fock mean-field calculations of candidate antiferromagnetic orders on a Wannier Hamiltonian, extracted from first-principle calculations targeting BaOsO$_3$. Our machine learning model was trained using various types of spectral data, including local density of states, momentum-resolved density of states at high-symmetry points, and the lowest excitation energies from the Fermi level. Although the density of states shows good performance for machine learning, the broadening method had a significant impact on the model's performance. We improved the model's performance by designing the excitation energy as a feature for machine learning, resulting in excellent classification of antiferromagnetic order, even for test samples generated by different methods from the training samples used for machine learning.

description: The American Time Use Survey (ATUS) is the premier dataset in the U.S. for understanding how Americans allocate their time across the multiple domains of daily life and is ideal for comparing time use during the COVID period and prior to the onset of the COVID-19 pandemic. However, data collection was paused in March 2020 and resumed in May 2020. This paper investigates the impact of this data collection pause and the partial-year sample weights on sample characteristics and time use outcomes. Our recommendation to researchers is to use full-year 2003-2019 data for trend analyses and the COVID-period 2020 data to focus on the impact of the COVID-19 pandemic on changes in time use. Based on several analyses, we conclude that there are multiple options for addressing the gap in 2020 data collection given the robustness of the sample and time use estimates to this omission. Comparing the full year of 2019 data and the May to December 2020 data, our time use analyses indicate that time spent in leisure, telephone calls, and household production increased during the pandemic, while time spent volunteering, traveling, religious activities, and shopping decreased significantly.

description: A Bianchi IX Mixmaster spacetime is the most general spatially homogeneous solution of Einstein's equations and it can represent the space-averaged Universe. We introduce two novel mechanisms resulting in a Mixmaster Universe with non-singular bounces which are quasi-isotropic. A fluid with a non-linear equation of state allows non-singular bounces. Using negative anisotropic stresses successfully isotropises this Universe and mitigates the well known Mixmaster chaotic behaviour. Thus the Universe can be an eternal Mixmaster, going through an infinite series of different cycles separated by bounces, with a sizable fraction of cycles isotropic enough to be well approximated by a standard Friedmann-Lemaître-Robertson-Walker model from the radiation era onward.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Geodetic earthquake early warning (EEW) algorithms complement point-source seismic systems by estimating fault-finiteness and unsaturated moment magnitude for the largest, most damaging earthquakes. Because such earthquakes are rare, it has been difficult to demonstrate that geodetic warnings improve ground motion estimation significantly. Here, we quantify and compare timeliness and accuracy of magnitude and ground motion estimates in simulated real time from seismic and geodetic observations for a suite of globally-distributed, large earthquakes. Magnitude solutions saturate for the seismic EEW algorithm (we use ElarmS) while the ElarmS-triggered Geodetic Alarm System (G-larmS) reduces the error even for its first solutions. Shaking intensity (MMI) time series calculated for each station and each event are assessed based on MMI-threshold crossings, allowing us to accurately characterize warning times per-station. We classify alerts and find that MMI 4 thresholds result in only 12.3% true positive (TP) alerts with a median warning time of 16.3 +- 20.9 s for ElarmS, but 44.4% TP alerts with a longer median warning time of 50.2 +- 49.8 s for G-larmS. The geodetic EEW system reduces the number of missed alerts for thresholds of MMI 3 and 4 by over 30%. If G-larmS was triggered instantaneously at the earthquake origin time, the performance statistics are similar, with slightly longer warning times and slightly more accurate magnitudes. By quantifying increased accuracy in magnitude, ground motion estimation, and alert timeliness; we demonstrate that geodetic algorithms add significant value, including better cost savings performance, to EEW systems.

description: The Institute for Social Research and Data Innovation (ISRDI) at the University of Minnesota submitted an application for approval to the Core Trust Seal (CTS) in June 2022. In the course of the protracted process of preparing ISRDI materials for the application, we learned five lessons that expanded our perspective on the role of the archive within our organization and committed the Institute to building a sustainable metadata culture. After reviewing the specialized nature of ISRDI as it developed over time, clarifying and documenting the processes that developed as the Intitute matured and expanded, and applying the standards and guidelines supported by the CTS, ISDRI staff are now better positioned to identify areas of future process development and to address outstanding needs for documenting and preserving the Institute’s work. These lessons are applicable to research organizations responsible for preserving a record of their work in the mid- and long-term.

description: Non-Hermitian quantum systems exhibit fascinating characteristics such as non-Hermitian topological phenomena and skin effect, yet their studies are limited by the intrinsic difficulties associated with their eigenvalue problems, especially in larger systems and higher dimensions. In Hermitian systems, the semiclassical theory has played an active role in analyzing spectrum, eigenstate, phase, transport properties, etc. Here, we establish a complex semiclassical theory applicable to non-Hermitian quantum systems by an analytical continuation of the physical variables such as momentum, position, time, and energy in the equations of motion and quantization condition to the complex domain. Further, we propose a closed-orbit scheme and physical meaning under such complex variables. We demonstrate that such a framework straightforwardly yields complex energy spectra and quantum states, topological phases and transitions, and even the skin effect in non-Hermitian quantum systems, presenting an unprecedented perspective toward nontrivial non-Hermitian physics, even with larger systems and higher dimensions.

Current Population Survey

description: The Current Population Survey (CPS) is the primary source of labor force data in the United States; the panel component of the CPS provides an excellent opportunity for studying short-run change in areas such as labor force participation and poverty. The Census Bureau's recommended procedures for linking CPS data occasionally yield a collection of matched observations that appears — based on demographic information — to represent different people rather than a single person across CPS files. We describe our methodology for assigning a unique identifier to records that share Census Bureau identifiers and have demographic characteristics that are consistent across observations. The identifier eliminates a currently-recommended step when working with linked CPS data – checking to ensure that records with a shared identifier look like the same individual based on age, sex, and race – and provides researchers a common starting point for analyzing validated CPS panel data. This identifier extends previous efforts at IPUMS CPS to create unique identifiers for leveraging the panel aspect of the CPS and are available from IPUMS CPS.

description: We report on the successful completion of a project to upgrade the positional accuracy of every response to the 1990, 2000, and 2010 U.S. decennial censuses. The resulting data set, called Optimized Spatial Census Information Linked Across Time (OSCILAT), resides within the restricted-access data warehouse of the Federal Statistical Research Data Center (FSRDC) system where it is available for use with approval from the U.S. Census Bureau. OSCILAT greatly improves the accuracy and completeness of spatial information for older censuses conducted prior to major quality improvements undertaken by the Bureau. Our work enables more precise spatial and longitudinal analysis of census data and supports exact tabulations of census responses for arbitrary spatial units, including tabulating responses from 1990, 2000, and 2010 within 2020 block boundaries for precise measures of change over time for small geographic areas.

description: The possibility of prescribing local interactions between nano- and microscopic components that direct them to assemble in a predictable fashion is a central goal of nanotechnology research. In this article we advance a new paradigm in which self-assembly of DNA-functionalized colloidal particles is programmed using linker oligonucleotides dispersed in solution. We find a phase diagram that is surprisingly rich compared to phase diagrams typical of other DNA-functionalized colloidal particles that interact by direct hybridization, including a re-entrant melting transition upon increasing linker concentration, and show that multiple linker species can be combined together to prescribe many interactions simultaneously. A new theory predicts the observed phase behavior quantitatively without any fitting parameters. Taken together, these experiments and model lay the groundwork for future research in programmable self-assembly, enabling the possibility of programming the hundreds of specific interactions needed to assemble fully-addressable, mesoscopic structures, while also expanding our fundamental understanding of the unique phase behavior possible in colloidal suspensions.

description: The thiophene extraction from model fuel by using N-methyl-2-pyrrolidone [NMP], dimethylformamide [DMF] and ethylene glycol [EG] as solvents had been carried out at atmospheric pressure. It is found that NMP showed the best performance with 98% removal of thiophene for 1 h. A detail parametric study was performed to investigate the effect of different process parameters on the extraction of thiophene by using NMP as the solvent. Finally Box-Behnken design (BBD) explores the relationship between output, sulfur removal efficiency and inputs parameters like time, temperature and solvent to model fuel volume ratio.

Two configurations are examined, for linear- and circular-polarized laser radiation, with the applied magnetic field collinear to the laser light wavevector. We describe the peculiarities of the Hanle signal for linearly-polarized laser excitation, characterized by narrow bright resonances at low laser intensities. The mechanism behind this effect is identified, and numerical solutions for the optical Bloch equations are presented for different transitions.

description: Basement membranes (BMs) are thin layers of condensed extracellular matrix proteins serving as permeability filters, cellular anchoring sites, and barriers against cancer cell invasion. It is believed that their biomechanical properties play a crucial role in determining cellular behavior and response, especially in mechanically active tissues like breast glands. In spite of this, so far relatively little attention has been dedicated to their analysis due to the difficulty of isolating and handling such thin layers of material. Here, we isolated basement membranes derived from MCF10A spheroids - 3D breast glands model systems mimicking in-vitro the most relevant phenotypic characteristics of human breast lobules - and characterized them by atomic force microscopy (AFM), enhanced resolution confocal microscopy (LSM), and scanning electron microscopy (SEM). By performing AFM height-clamp experiments, we obtained force relaxation curves that offered the first biomechanical data on isolated breast gland BMs. Based on LSM and SEM imaging data, we modeled the system as a polymer network immersed in liquid and described it as a poroelastic material. Finite Element (FE) simulations matching the experimental force relaxation curves allowed for the first quantification of the bulk and shear moduli of the membrane, as well as its water permeability. These results represent a first step towards a deeper understanding of the mechanism of tensional homeostasis regulating mammary gland activity, as well as its disruption during processes of membrane breaching and metastatic invasion.

description: IPUMS at the University of Minnesota has created the world's largest accessible database of census and survey microdata. The IPUMS suite of products contains nine harmonized data products. The largest of these projects, IPUMS International (IPUMS-I) has supported the curation and preservation of ancillary materials received during data acquisition efforts. Archival staff have preserved thousands of unique pieces of census and survey documentation, creating bibliographic records using an extended Dublin Core profile that supports the use of controlled vocabularies to enhance findability. The goal of this curation work was to create a searchable, and downloadable document access system for our internal use and to support IPUMS researchers. This paper describes our experience constructing a tool that supports exploration and dissemination of these archived materials. During this development, we gained valuable insight about stewarding our resources that are applicable to research organizations responsible for curating, preserving, and disseminating similar archival materials.

description: Objective: We investigated adherence barriers to inhaled medicines among older compared to younger adults with asthma in Japan. Methods: Adherence barriers to inhaled medicines were evaluated in 251 Japanese older (n = 138) and younger (n = 113) adults with asthma using the self-reporting “Adherence Starts with Knowledge 20” (ASK-20) questionnaire. Results: There were fewer older adults with poor adherence to inhaled medicines than younger adults. The ASK-20 questionnaire revealed (odds ratio [95% confidence interval]) item Q11 (“My doctor/nurse and I work together to make decisions”; 2.94 [1.31, 6.61]; p < 0.05) as an independent adherence barrier to inhaled medicines among older adults, whereas younger adults reported item Q3 (“My use of alcohol gets in the way of taking my medicines”; 3.91 [1.02 to 15.1]; p < 0.05) and item Q16 (“Taken a medicine more or less often than prescribed? “; 2.31 [1.32 to 4.06]; p < 0.05) as barriers. Older adults with poor adherence identified item Q1 (“I just forget to take my inhaled medicines some of the time”; 4.43 [1.77, 11.1]; p < 0.05) as a barrier, although the total ASK-20 scores and total barrier counts were significantly higher in older (both, p < 0.05) and younger (both, p < 0.05) adults with poor adherence than in those with good adherence. Conclusion: Older Japanese patients had better adherence to inhaled medicines than younger patients. Barriers were different between older and younger adults. These results will help personalize education for inhaled medicines in Japanese asthmatics.

description: We demonstrate slow dynamics and constrained motion of domain walls in one-dimensional (1D) interacting bosons with double-well dispersion. In the symmetry-broken regime, the domain-wall motion is ``fractonlike'' -- a single domain wall cannot move freely, while two nearby domain walls can move collectively. Consequently, we find an Ohmic-like linear response and a vanishing superfluid stiffness, which are atypical for a Bose condensate in a 1D translation invariant closed quantum system. Near Lifshitz quantum critical point, we obtain superfluid stiffness $ρ_s\sim T$ and sound velocity $v_s\sim T^{1/2}$, showing similar unconventional low-temperature slow dynamics to the symmetry-broken regime. Particularly, the superfluid stiffness suggests an order by disorder effect as $ρ_s$ increases with temperature. Our results pave the way for studying fractons in ultracold atom experiments.

description: We study the time evolution of a sessile liquid droplet, which is initially put onto a solid surface in a non-equilibrium configuration and then evolves towards its equilibrium shape. We adapt here the standard approach to the dynamics of mechanical dissipative systems, in which the driving force, i.e. the gradient of the system's Lagrangian function, is balanced against the rate of the dissipation function. In our case the driving force is the loss of the droplet's free energy due to the increase of its base radius, while the dissipation occurs due to viscous flows in the core of the droplet and due to frictional processes in the vicinity of the advancing contact line, associated with attachment of fluid particles to solid. Within this approach we derive closed-form equations for the evolution of the droplet's base radius, and specify several regimes at which different dissipation channels dominate. Our analytical predictions compare very well with experimental data.

description: The superconductor to insulator or metal transition in two dimensions (2D) provides a valuable platform for studying continuous quantum phase transitions (QPTs) and critical phenomena. Distinct theoretical models, including both fermionic and bosonic localization scenarios, have been developed, but many questions remain unsettled despite decades of research. Extending Nernst experiments down to millikelvin temperatures, we uncover anomalous quantum fluctuations and identify an unconventional superconducting quantum critical point (QCP) in a gate-tuned excitonic quantum spin Hall insulator (QSHI), the monolayer tungsten ditelluride (WTe2). The observed vortex Nernst effect reveals singular superconducting fluctuations in the resistive normal state induced by magnetic fields or temperature, even well above the transition. Near the doping-induced QCP, the Nernst signal driven by quantum fluctuations is exceptionally large in the millikelvin regime, with a coefficient of ~ 4,100 uV/KT at zero magnetic field, an indication of the proliferation of vortices. Surprisingly, the Nernst signal abruptly disappears when the doping falls below the critical value, in striking conflict with conventional expectations. This series of phenomena, which have no prior analogue, call for careful examinations of the mechanism of the QCP, including the possibility of a continuous QPT between two distinct ordered phases in the monolayer. Our experiments open a new avenue for studying unconventional QPTs and quantum critical matter.
Leveraging eBPF for programmable network functions with IPv6 Segment Routing

description: With the advent of Software Defined Networks (SDN), Network Function Virtualisation (NFV) or Service Function Chaining (SFC), operators expect networks to support flexible services beyond the mere forwarding of packets. The network programmability framework which is being developed within the IETF by leveraging IPv6 Segment Routing enables the realisation of in-network functions. In this paper, we demonstrate that this vision of in-network programmability can be realised. By leveraging the eBPF support in the Linux kernel, we implement a flexible framework that allows network operators to encode their own network functions as eBPF code that is automatically executed while processing specific packets. Our lab measurements indicate that the overhead of calling such eBPF functions remains acceptable. Thanks to eBPF, operators can implement a variety of network functions. We describe the architecture of our implementation in the Linux kernel. This extension has been released with Linux 4.18. We illustrate the flexibility of our approach with three different use cases: delay measurements, hybrid networks and network discovery. Our lab measurements also indicate that the performance penalty of running eBPF network functions on Linux routers does not incur a significant overhead.

description: This article describes the development of IPUMS full count datasets of the censuses of slave inhabitants of the United States in 1850 and 1860. These data are a result of two collaborations. The 1850 slave dataset stems from a collaboration between the Church of Jesus Christ of Latter-day Saints, whose volunteers transcribed the original manuscript forms, and IPUMS, which enhanced the raw data with editing, standardized coding procedures, constructed variables, and documentation. The 1860 dataset was the result of a similar collaboration between the genealogical company Ancestry and IPUMS. The article discusses the features of these datasets, their limitations, and suggests possible research uses.

Distinctly different dependences of coherence times on mobility, quantization energy, and temperature are found from previous calculations. Quantitative agreement between our calculations and measurements is found for GaAs/AlGaAs, InGaAs/InP, and GaSb/AlSb quantum wells.
