description: IPUMS has finalized databases for each of the United States population censuses from 1850 to 1880. These data are the result of collaborations between FamilySearch and Ancestry.com, which provided the raw data, and IPUMS, which enhanced the data with editing, standardized coding, inter-census harmonization, and documentation. We discuss the data capture process conducted by the nineteenth-century United States Census Office, construction of the modern datasets, and variable availability. We conclude by briefly discussing the potential and limitations of these data for social science research. The public data are distributed by IPUMS and available for researchers to use free of charge.

Universal quantum computation with spin-1/2 pairs and Heisenberg exchange
Creators: name: Levy, Jeremy
Publisher: name: arXiv
Year: 2001
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: An efficient and intuitive framework for universal quantum computation is presented that uses pairs of spin-1/2 particles to form logical qubits and a single physical interaction, Heisenberg exchange, to produce all gate operations. Only two Heisenberg gate operations are required to produce a controlled pi-phase shift, compared to 19 for exchange-only proposals employing three spins. Evolved from well-studied decoherence-free subspaces, this architecture inherits immunity from collective decoherence mechanisms. The simplicity and adaptability of this approach should make it attractive for spin-based quantum computing architectures.

The measurement of bovine pericardium density and its implications on leaflet stress distribution in bioprosthetic heart valves
Creators: name: Sadipour, Masod

Publisher: name: arXiv
Year: 2023
Subjects: subject: Tissues and Organs (q-bio.TO)
subject: FOS: Biological sciences

description: Purpose: Bioprosthetic Heart Valves (BHVs) are currently in widespread use with promising outcomes. Computational modeling provides a framework for quantitatively describing BHVs in the preclinical phase. To obtain reliable solutions in computational modeling, it is essential to consider accurate leaflet properties such as mechanical properties and density. Bovine pericardium (BP) is widely used as BHV leaflets. Previous computational studies assume BP density to be close to the density of water or blood. However, BP leaflets undergo multiple treatments such as fixation and anti-calcification. The present study aims to measure the density of the BP used in BHVs and determine its effect on leaflet stress distribution.
 Methods: We determined the density of eight square BP samples laser cut from Edwards BP patches. The weight of specimens was measured using an A&D Analytical Balance, and volume was measured by high-resolution imaging. Finite element models of a BHV similar to PERIMOUNT Magna were developed in ABAQUS.
 Results: The average density value of the BP samples was 1410 kg/m3. In the acceleration phase of a cardiac cycle, the maximum stress value reached 1.89 MPa for a density value of 1410 kg/m3 , and 2.47 MPa for a density of 1000 kg/m3(30.7% difference). In the deceleration, the maximum stress value reached 713 and 669 kPa, respectively.
 Conclusion: Stress distribution and deformation of BHV leaflets are dependent upon the magnitude of density. Ascertaining an accurate value for the density of BHV leaflets is essential for computational models.

description: Background: Arterial hypertension is associated with obstructive sleep apnoea, poor quality and duration of sleep, which might contribute to hypertension-mediated organ damage. Methods: We investigated the presence of insomnia, restless legs syndrome, and obstructive sleep apnoea using validated questionnaires (Insomnia Severity Index, Restless Legs Syndrome Rating Scale, and STOP-Bang), and their relationship with hypertension-mediated organ damage, in hypertensive patients. Results: In 159 consecutive consenting hypertensive patients [age 47(11) years, median and (interquartile range), body mass index 25.5(5.9) kg/m2, office systolic and diastolic blood pressure 144(23)/92(12) mmHg], the STOP-Bang, but not the other scores, predicted cardiac remodelling: compared to patients with a STOP-Bang score < 3, those at high risk of obstructive sleep apnoea showed higher left ventricular mass index [49.8(11.9) vs. 43.3(11.9) g/m2.7, p vs. 25.0(2.8) ml/m2, p = 0.003], and aortic root diameter [33.6(3.0) vs. 33.0(3.7) mm, p Conclusions: In consecutive hypertensive stage I patients the STOP-Bang questionnaire allowed identification of a high-risk cohort featuring a more prominent cardiac damage.

title: The IPUMS Business Process Model: Instituting a Workflow Mapping Strategy to Support Archival Processes
Creators: name: Magnuson, Diana L.
Publisher: name: Minneapolis, MN: IPUMS
Year: 2024

description: The IPUMS Preservation Archive is instituting a workflow mapping strategy to further identify IPUMS process and metadata capture points to expand its holdings in the data archive. Drawing on two business process models, the Generic Statistical Business Process Model (GSBPM) and the Generic Longitudinal Business Process Model (GLBPM), archival staff have created an IPUMS Business Process Model (IPUMS BPM). The IPUMS BPM reflects the use of secondary data sources and the work of harmonization and integration to create a data infrastructure that supports research across time and space. Internally, the IPUMS BPM provides a clear visualization of the IPUMS workflow from external submission of data, harmonization process, documentation, extraction systems, and archival preservation of metadata. The challenge for archival staff is furthering the understanding and adoption of the IPUMS BPM within the IPUMS project groups, and to identify metadata production points that require the intervention of the archive for provenance and preservation purposes. This paper identifies the value of instituting this mapping approach to gain a clearer understanding of the role of the archive within project work cycles, points where production and preservaton activities intersect, and opportunities to expand archival holdings.

The three point solid-solid correlation function is derived and utilised in the evaluation of the Beran-Milton bounds. Simulations are used to calculate $σ_e$ for a variety of fields and volume fractions at several different conductivity contrasts. Relatively large differences in $σ_e$ are observed between the Gaussian media and the identical overlapping sphere model used previously as a `model' amorphous medium. In contrast $σ_e$ shows little variability between different Gaussian media.

description: For 25 years, the US federal standards for collecting data on race have required that people be allowed to report multiple races. The current federal race/ethnicity data collection standards have proven challenging for analysts who find the large number of categories impractical. Also, some data sources have been slower to collect high-quality and analyzable multiple-race data. To enable studies that use data sources with different race/ethnic collection strategies, multiple-race responses must be “bridged” into a small number of simplified categories. The simplified categories are meaningful and inclusive, making them useful for other analytic purposes as well. This report describes the development of updated coefficients for bridging and provides them to interested readers. It also describes three ways that resulting data are being disseminated: as microdata with whole allocation, as microdata with fractional allocation, and as aggregate data based on fractional allocation. The race/ethnic categories in the simplified, bridged race/ethnicity variables are: Hispanic/Latino, non Hispanic/Latino (NH) American Indian or Alaska Native, NH Asian or Pacific Islander, NH Black, and NH White. To illustrate the utility of the simplified race/ethnicity variables, the report ends by showing the estimated total number of US persons who would have been reported as one of the five simplified race/ethnicity groups in 2000 to 2019.

description: We investigate the influence of fractal structure on material properties. We calculate the statistical correlation functions of fractal media defined by level-cut Gaussian random fields. This allows the modeling of both surface fractal and mass fractal materials. Variational bounds on the conductivity, diffusivity and elastic moduli of the materials are evaluated. We find that a fractally rough interface has a relatively strong influence on the properties of composites. In contrast a fractal volume (mass) has little effect on material properties.

description: IPUMS recently released final versions of full count census data for the United States 1900-1930. The information contained in these files is the product of three broad work stages: historical census enumeration, digitization, and IPUMS processing. The data were produced within an evolving institutional context and subjected to subsequent processes that had important ramifications on the final product. This paper documents these histories and processes and their implications for research. Because of the datasets’ sheer size and scale, the development of these files necessitated applying different methods and approaches to assess data quality and correct the data. We document cases where data quality was affected not only by choices made by the Census historically, but also by data transcription errors in the modern day. Finally, we describe our approaches to processing the data, and we note some of the implications for research these various decisions have. As with any dataset, researchers should use this resource critically for their particular research questions and consider the data creation process from respondent to digital dataset. Despite some limitations and liabilities, the IPUMS full count data provide a powerful and valuable resource to study demographic effects on a variety of health and socioeconomic questions.

description: As self-management support is a cost-effective way to enable patients to take an active role in managing their own condition and to address the chronic disease burden, there is a need for contextually appropriate self-management support tools. This study explored the feasibility of using a contextually adapted self-management care-plan booklet for diabetes and hypertension for use in medical consultations in a middle-income country. Focus groups and individual interviews with patients and health care providers were conducted in three primary health care facilities. Four relevant focus areas for feasibility studies were used as the lens for data analysis: acceptability, demand, implementation, practicality. The study revealed a high acceptance of the care-plan booklet by both patients and providers. Patients reported that the booklet increased their knowledge of their conditions. They also indicated that they would share the booklet with friends and families and expressed the need to use it with their providers. Providers mentioned that community health workers and health promoters could play an important role in implementing the tool. The findings of this study contribute to the knowledge base needed for the development and adoption of the self-management component of the South African integrated chronic diseases model. The care-plan booklet can be used to stimulate the interaction between patients, providers and/or family and friends.

We then detail our plans for expansion and improvement of MLP over the next five years, including the incorporation of additional data sources, the development of a "linkage hub" to connect MLP with other major record linkage efforts, and the refinement of our technology and dissemination efforts. We conclude by describing a few early examples of MLP-based research.

description: Collecting and annotating images with pixel-wise labels is time-consuming and laborious. In contrast, synthetic data can be freely available using a generative model (e.g., DALL-E, Stable Diffusion). In this paper, we show that it is possible to automatically obtain accurate semantic masks of synthetic images generated by the Off-the-shelf Stable Diffusion model, which uses only text-image pairs during training. Our approach, called DiffuMask, exploits the potential of the cross-attention map between text and image, which is natural and seamless to extend the text-driven image synthesis to semantic mask generation. DiffuMask uses text-guided cross-attention information to localize class/word-specific regions, which are combined with practical techniques to create a novel high-resolution and class-discriminative pixel-wise mask. The methods help to reduce data collection and annotation costs obviously. Experiments demonstrate that the existing segmentation methods trained on synthetic data of DiffuMask can achieve a competitive performance over the counterpart of real data (VOC 2012, Cityscapes). For some classes (e.g., bird), DiffuMask presents promising performance, close to the stateof-the-art result of real data (within 3% mIoU gap). Moreover, in the open-vocabulary segmentation (zero-shot) setting, DiffuMask achieves a new SOTA result on Unseen class of VOC 2012.

description: We present a novel inequality on the purity of a bipartite state depending solely on the difference of the local Bloch vector lengths. For two qubits this inequality is tight for all marginal states and so extends the previously known solution for the 2-qubit marginal problem and opens a new research avenue. We further use this inequality to construct a 3-dimensional Bloch model of the 2-qubit quantum state space in terms of Bloch lengths, thus providing a geometrically pleasing visualization of this difficult to access high-dimensional state space. This allows to characterize quantum states relying on a strongly reduced set of parameters alone and to investigate the interplay between local properties of the marginal systems and global properties encoded in the correlations.

description: Ursolic acid (UA), a plant-derived compound, has many properties beneficial to health. In the present study, we synthesised three series of novel UA derivatives and evaluated their anti-Toxoplasma gondii activity both in vitro and in vivo. Most derivatives exhibited an improved anti-T. gondii activity in vitro when compared with UA (parent compound), whereas compound 3d exhibited the most potent anti-T. gondii activity in vivo. Spiramycin served as the positive control. Additionally, determination of biochemical parameters, including the liver and spleen indexes, indicated compound 3d to effectively reduce hepatotoxicity and significantly enhance anti-oxidative effects, as compared with UA. Furthermore, our molecular docking study indicated compound 3d to possess a strong binding affinity for T. gondii calcium-dependent protein kinase 1 (TgCDPK1). Based on these findings, we conclude that compound 3d, a derivative of UA, could act as a potential inhibitor of TgCDPK1.

description: Neural video game simulators emerged as powerful tools to generate and edit videos. Their idea is to represent games as the evolution of an environment's state driven by the actions of its agents. While such a paradigm enables users to play a game action-by-action, its rigidity precludes more semantic forms of control. To overcome this limitation, we augment game models with prompts specified as a set of natural language actions and desired states. The result-a Promptable Game Model (PGM)-makes it possible for a user to play the game by prompting it with high- and low-level action sequences. Most captivatingly, our PGM unlocks the director's mode, where the game is played by specifying goals for the agents in the form of a prompt. This requires learning "game AI", encapsulated by our animation model, to navigate the scene using high-level constraints, play against an adversary, and devise a strategy to win a point. To render the resulting state, we use a compositional NeRF representation encapsulated in our synthesis model. To foster future research, we present newly collected, annotated and calibrated Tennis and Minecraft datasets. Our method significantly outperforms existing neural video game simulators in terms of rendering quality and unlocks applications beyond the capabilities of the current state of the art. Our framework, data, and models are available at https://snap-research.github.io/promptable-game-models/.

description: Some spectroscopies are intrinsically poorly sensitive, such as nuclear magnetic resonance (NMR) and Raman spectroscopy. This drawback can be overcome by using singular value decomposition (SVD) and low-rank approximation to denoise spectra and consequently increase sensitivity. However, SVD limits have not been deeply investigated until now. We applied SVD to NMR and Raman spectra and showed that best results were obtained with a square data set in time domain. Automatic thresholding was applied using Malinowski’s indicators. 6 × 7380 noisy spectra with 41 signal-to-noise ratios were compared to their non-noisy counterparts, highlighting that SVD induces a systematic error for Gaussian peaks but faithfully reproduces shape of Lorentzian peaks, thus allowing quantification. Used carefully, SVD can decrease experimental time by a factor of 2.3 for spectroscopies. This study may help scientists to apply SVD to denoise spectra in a more efficient way, without falling into pitfalls.

description: A number of dense particle suspensions experience a dramatic increase in viscosity with the shear stress, up to a solid-like response. This shear-thickening process is understood as a transition under flow of the nature of the contacts, from lubricated to frictional, between initially repellent particles. Most systems are now assumed to fit in with this scenario, which is questionable. Using an in-house pressure sensor array, we provide a spatio-temporal map of the normal stresses in the flows of two shear-thickening fluids: a stabilised calcium carbonate suspension, known to fit in with the standard scenario, and a cornstarch suspension, which spectacular thickening behavior remains poorly understood. We evidence in cornstarch a unique, stable heterogeneous structure, which moves in the velocity direction and does not appear in calcium carbonate. Its nature changes from a stress wave to a rolling solid jammed aggregate at high solid fraction and small gap width. The modeling of these heterogenities points to an adhesive force between cornstarch particles at high stress, also evidenced in microscopic measurements. Cornstarch being also attractive at low stress, it stands out of the classical shear-thickening frame, and might be part of a larger family of adhesive and attractive shear-thickening fluids.

description: Using first-principles calculations based on a variational density functional perturbation theory, we investigate the lattice dynamics of solid solutions of barium and strontium titanates. Averaging the information available for the related pure compounds yields results equivalent to those obtained within the virtual crystal approximation, providing frequencies which are a good approximation to those computed for a (111) ordered supercell. Using the same averaging technique we report the evolution of the ferroelectric and antiferrodistortive instabilities with composition.

description: Mechanical and tribological properties of Aluminium-1100 substrate modified locally by infusing multi-walled carbon nanotubes (MWCNTs) are presented in this paper. MWCNTs were mechanically impregnated onto Al-1100 substrate through an electric resistance heat-assisted solid-state processing route. Presence of MWCNTS with extraordinary mechanical properties and, high specific surface area enhances the surface mechanical behaviour of Al-1100 to a great extent. The microhardness results show an improvement >250%. An in-depth tribological study was carried out, and the findings suggest that the specific wear rate and the coefficient of friction reduced by >90%. Detailed microstructural analysis, Raman spectroscopy and X-ray diffraction studies corroborate the experimental observations.

description: The equilibrium properties of isolated ring molecules were investigated using an off-lattice model with no excluded volume but with dynamics that preserve the topological class. Using an efficient set of long range moves, chains of more than 2000 monomers were studied. Despite the lack of any excluded volume interaction, the radius of gyration scaled like that of a self avoiding walk, as had been previously conjectured. However this scaling was only seen for chains greater than 500 monomers.

description: Entanglement in fishing gear is inhibiting the recovery of North Atlantic right whales (Eubalaena glacialis). Low breaking-strength (LBS) modifications have the potential to reduce severity of entanglements. The first part of this thesis aims to assess if LBS components have sufficient strength to withstand conditions in the Newfoundland and Labrador snow crab (Chionoecetes opilio) fishery by documenting tensions while hauling. Results showed that tension regularly exceeded the 771 kgf LBS threshold when hauling traps, suggesting that they are not suitable for this fishery. The second part involved assessing time-tension line cutters (TTLCs), a double-threshold (time and tension) entanglement mitigation device. Due to their use of hydraulic fluid and the known effect of temperature on its viscosity, a controlled laboratory experiment reflecting the conditions of Atlantic fisheries was conducted to evaluate the effect of temperature on time to cut (TTC). Results revealed that for every unit increase in temperature (1°C), time to cut was reduced by 0.759 min. Additionally, extreme TTC values at the lowest temperature tested showed further development and testing are needed. This thesis presents several novel methods and findings with direct application to one of Canada’s most economically important fisheries and the innovation of entanglement mitigation devices.

description: The visual world paradigm (VWP) studies of spoken word recognition rely on a linking hypothesis that connects lexical activation to the probability of looking at the referent of a word. The standard hypothesis is that fixation probabilities track activation levels transformed via the Luce Choice Rule. Under this assumption, given enough power, any difference between positive activations should be detectable using VWP. We argue that looking at a referent of a word is a decision, made when the word’s activation exceeds a context-specific threshold. Subthreshold activations do not drive saccades, and differences among such activations are undetectable in VWP. Evidence is provided by VWP experiments on Japanese. Bayesian analyses indicate a relatively high threshold: saccades to cohort competitors do not exceed those to unrelated distractors unless the cohort competitor shares the initial CVC with the target. We argue that threshold setting constitutes an understudied source of variability in VWP data.

description: We consider two families of exactly solvable models describing thermal fluctuations in two-dimensional superconductors coupled to phonons living in an insulating layer, and study the stability of the superconducting state with respect to vortices. The two families are characterized by one or two superconducting planes. The results suggest that the effective critical temperature increases with the thickness of the insulating layer. Also the presence of the additional superconducting layer has the same effect.

description: Colombian Pacific region is a global biodiversity hotspot. Mangroves are among the most dynamic and productive ecosystem on earth and serve many important functions providing a range of fundamental goods and services which contribute to the livelihoods, well – being, and local community’s security. Integral mangroves valuation seeks to understand the socio-ecological interaction and the relationship between functional ecosystems (ecosystem services – ES), market interaction and the ability to support human well – being. Despite the importance, mangroves are continuing to be threatened and degraded because of socio-environmental conflicts such as land use change and port infrastructure which will impact on ecosystem services quality and offer. This article identifies an approach to the potential ecological, sociocultural and economic impact of a Deepwater port on the Tribugá Gulf mangroves ecosystem services offer and its effects on the well – being of Nuquí communities.

description: Achieving topologically-protected robust transport in optical systems has recently been of great interest. Most topological photonic structures can be understood by solving the eigenvalue problem of Maxwell's equations for a static linear system. Here, we extend topological phases into dynamically driven nonlinear systems and achieve a Floquet Chern insulator of light in nonlinear photonic crystals (PhCs). Specifically, we start by presenting the Floquet eigenvalue problem in driven two-dimensional PhCs and show it is necessarily non-Hermitian. We then define topological invariants associated with Floquet bands using non-Hermitian topological band theory, and show that topological band gaps with non-zero Chern number can be opened by breaking time-reversal symmetry through the driving field. Furthermore, we show that topological phase transitions between Floquet Chern insulators and normal insulators occur at synthetic Weyl points in a three-dimensional parameter space consisting of two momenta and the driving frequency. Finally, we numerically demonstrate the existence of chiral edge states at the interfaces between a Floquet Chern insulator and normal insulators, where the transport is non-reciprocal and uni-directional. Our work paves the way to further exploring topological phases in driven nonlinear optical systems and their optoelectronic applications, and our method of inducing Floquet topological phases is also applicable to other wave systems, such as phonons, excitons, and polaritons.
