Abstract
We report the crystal structure of Nd–Fe alloys as candidates for grain-boundary phases in Nd–Fe–B sintered magnets. We find that the crystal structure of the fluorite Nd–Fe alloys is stable for a wide composition range. We also demonstrate that solid solution of Ga is effective in stabilizing the fluorite crystal structure of Nd–Fe alloys, which is consistent with experimental observations reporting crystalline Nd–Fe alloys at the grain boundaries of Ga-added Nd–Fe–B permanent magnets.

Unmet Workplace Support Needs and Lost Productivity of Workers With Systemic Sclerosis: A Path Analysis Study
Authors: Jetha Arif , Johnson Sindhu R. , Gignac Monique A. M. 
Published: December 2019

ObjectiveFew studies have examined how workplace support can address work productivity loss among individuals with systemic sclerosis (SSc). The objective was to 1) examine the relationship between unmet workplace support needs and work productivity loss among workers with SSc, and 2) determine whether SSc symptom severity, fatigue, active disease periods, and workplace activity limitations mediate the relationship between unmet workplace support needs and work productivity loss.MethodsA cross‐sectional survey was conducted of employed individuals with SSc who were recruited through rheumatology clinics. Information on work productivity loss (i.e., absenteeism, presenteeism, job disruptions) and the need, availability, and use of workplace supports was collected. SSc symptom severity (e.g., workplace activity limitations, active disease periods, fatigue, and overall SSc symptom severity) and demographic, health, and work context characteristics were collected. Three Bayesian path models examined the association between unmet workplace support needs and each work productivity loss outcome. SSc symptom severity variables were examined as mediators in each model.ResultsA total of 110 employed participants were recruited (mean ± SD ages 49 ± 12.9 years). More than three‐fourths of participants were female (77%) and worked full‐time (77%). The most needed workplace supports included extended health benefits (84%), special equipment (63%), and flextime (59%). Additionally, 61% reported unmet workplace support needs. Path models indicated that indirect relationships between unmet workplace support needs and work productivity loss were significant. For all models, workplace activity limitations mediated the relationship between unmet workplace support needs and productivity loss.ConclusionTo foster productive employment of individuals with SSc, interventions need to address symptom severity and meet workplace support needs.

ObjectiveDigital ulcers (DUs) are a major cause of disease‐related morbidity and are a difficult‐to‐treat vascular complication of systemic sclerosis (SSc). Demonstrating treatment efficacy has traditionally focused on clinician assessment of DUs alone. No existing patient‐reported outcome (PRO) instrument captures the multifaceted impact of SSc‐DU. We report the findings of a multicenter qualitative research study exploring the patient experience of SSc‐DU.MethodsPatient focus groups were conducted across 3 scleroderma units, following a topic guide devised by SSc patients, experts, and experienced qualitative researchers. A purposive sampling framework ensured that the experiences of a diverse group of patients were captured. Focus groups were audio recorded, and information was transcribed, anonymized, and analyzed using inductive thematic analysis. We continued focus groups until thematic saturation was achieved.ResultsTwenty‐nine SSc patients with a history of DU disease participated in 4 focus groups across the UK (Bath, Manchester, and London). Five major interrelated themes (and subthemes) were identified that encompass the patient experience of SSc‐DU: disabling pain and hypersensitivity; deep and broad‐ranging emotional impact; impairment of physical and social activity; factors aggravating occurrence, duration, and impact; and mitigating, managing, and adapting.ConclusionThe patient experience of SSc‐DU is multifaceted and comprises a complex interplay of experiences associated with significant pain and morbidity. Patient experiences of SSc‐DU are not captured using existing SSc‐DU outcomes. Our findings will inform the development of a novel PRO instrument to assess the severity and impact of SSc‐DU for use in future SSc‐DU clinical trials.

Published: December 2019

AbstractA topological insulator (TI) is a kind of novel material hosting a topological band structure and plenty of exotic topological quantum effects. Achieving quantized electrical transport, including the quantum Hall effect (QHE) and the quantum anomalous Hall effect (QAHE), is an important aspect of realizing quantum devices based on TI materials. Intense efforts are made in this field, in which the most essential research is based on the optimization of realistic TI materials. Herein, the TI material development process is reviewed, focusing on the realization of quantized transport. Especially, for QHE, the strategies to increase the surface transport ratio and decrease the threshold magnetic field of QHE are examined. For QAHE, the evolution history of magnetic TIs is introduced, and the recently discovered magnetic TI candidates with intrinsic magnetizations are discussed in detail. Moreover, future research perspectives on these novel topological quantum effects are also evaluated.

AbstractRuddlesden–Popper halide perovskite (RPP) materials are of significant interest for light‐emitting devices since their emission wavelength can be controlled by tuning the number of layers n, resulting in improved spectral stability compared to mixed halide devices. However, RPP films typically contain phases with different n, and the low n phases tend to be unstable upon exposure to humidity, irradiation, and/or elevated temperature which hinders the achievement of pure blue emission from n = 2 films. In this work, two spacer cations are used to form an RPP film with mixed cation bilayer and high n = 2 phase purity, improved stability, and brighter light emission compared to a single spacer cation RPP. The stabilization of n = 2 phase is attributed to favorable formation energy, reduced strain, and reduced electron–phonon coupling compared to the RPP films with only one type of spacer cation. Using this approach, pure blue light‐emitting diodes (LEDs) with Commission Internationale de l'éclairage (CIE) coordinates of (0.156, 0.088) and excellent spectral stability are achieved.

AbstractNegative capacitance in ferroelectrics has seem remarkable progress in recent years. However, direct measurement of negative capacitance has so far been a challenge due to its instable characteristic in the electrostatic field. An ingenious method to design stable negative capacitance by dielectric resonance under high‐frequency alternating electric fields is demonstrated. The well‐pronounced dielectric resonance and electrical property in BaTiO3/SrTiO3 (BT/ST) bulk ceramics consisted of epitaxial core–shell particles are studied. As the negative capacitance can be considered as an inductive behavior, the dielectric resonance of permittivity induced by a LC resonance can be occurred. The dielectric resonance can be described by the Lorentz model and explained by Fano‐like resonance of TO2 phonon in BT. In addition, lowest resonant frequency is observed at effective Curie temperature. Benefiting from negative capacitance in the BT/ST ceramics, both high permittivity and negative permittivity are accompanied with low losses around the resonant frequency, which is useful for developing capacitors and metamaterials. Significantly, this work will provide an initiative avenue to obtain explicit negative capacitance of ferroelectrics in the frequency spectrum.

Published: December 2019

AbstractThe waves of liquid film flow play an important role on the process intensification in spinning disk reactors (SDRs). However, the mechanism of wave formation was still unclear. In this work, a three‐dimensional large eddy simulation was developed to investigate the mechanism, as well as the characteristics of waves in the SDR. Agreed with the imaging results, different wave patterns were identified as: smooth film, concentric, and spiral waves in spreading direction; sine‐like and pulse‐like waves in fluctuating direction. The radial and tangential relative movements among the layers of liquid film were found to dominate the formation of different wave patterns. Local average film thickness (havg) and local wave amplitude (Δh) ranged from 0 to 500 μm and 0 to 200 μm, respectively. The waves can improve the turbulent intensity and enlarge the specific surface area, resulting in the intensification of transfer processes.

AbstractHigher and lower hemoglobin concentrations are associated with coronary heart disease (CHD), but whether this risk is consistent across age, sex, and race is unclear. The Reasons for Geographic And Racial Differences in Stroke (REGARDS) study is an observational cohort study of 30 239 black, and white, adults aged 45 and older recruited 2003‐7. Participants were included if they had hemoglobin measures, were CHD‐free at baseline, and had all baseline variables. The primary outcome was incident CHD. Multivariable Cox proportional hazards models were used to estimate the hazard ratios (HR) and 95% confidence intervals (CI) for incident CHD by hemoglobin concentration. This was expressed as a continuous variable and divided into age‐, sex‐, and race‐specific quintiles. The 16 332 participants were included, contributing 114 362 person‐years of follow‐up and 915 incident CHD events. The mean age was 63 years, 35% were male, 41% were black, and the mean baseline hemoglobin was 13.6 g/dL (SD 1.4). A significant non‐linear association between hemoglobin and CHD was identified (P < .001). This association differed significantly by race (P = .025) but not by sex or age. In whites, the risk for incident CHD was higher in the lowest (HR 2.28, 95% CI 1.61, 3.33) and highest (HR 1.94, 95% CI 1.35, 2.79) hemoglobin quintiles relative to the third quintile. For blacks, only those in the lowest hemoglobin quintile had an increased risk for incident CHD events (HR 1.70, 95% CI 1.20, 2.41). Hemoglobin is an independent risk factor for CHD in whites and blacks but with different hemoglobin concentrations conferring different risks.
Scientific journals still matter in the era of academic search engines and preprint archives

Published: December 2019

AbstractJournals play a critical role in the scientific process because they evaluate the quality of incoming papers and offer an organizing filter for search. However, the role of journals has been called into question because new preprint archives and academic search engines make it easier to find articles independent of the journals that publish them. Research on this issue is complicated by the deeply confounded relationship between article quality and journal reputation. We present an innovative proxy for individual article quality that is divorced from the journal's reputation or impact factor: the number of citations to preprints posted on arXiv.org. Using this measure to study three subfields of physics that were early adopters of arXiv, we show that prior estimates of the effect of journal reputation on an individual article's impact (measured by citations) are likely inflated. While we find that higher‐quality preprints in these subfields are now less likely to be published in journals compared to prior years, we find little systematic evidence that the role of journal reputation on article performance has declined.
