Step by step rare-earth catalyzed SiOx annealing and simultaneous formation of Europium- silicide by low coverage of Eu doped Gd2O3 nanoparticles

We report the formation of silicide by annealing of a SiOx surface, with low coverage of Eu doped Gd2O3 nanoparticles. The annealing temperature required for removal of native oxide from the Si substrate decreases with close to 200 °C in presence of the nanoparticles. X-ray photoemission electron microscopy, low-energy electron microscopy and mirror electron microscopy are used to monitor the sili

Toeplitz-based blind deconvolution of underwater acoustic channels using wideband integrated dictionaries

In this paper, we propose a blind channel deconvolution method based on a sparse reconstruction framework exploiting a wideband dictionary under the (relatively weak) assumption that the transmitted signal may be assumed to be well modelled as a sum of sinusoids. Using a Toeplitz structured formulation of the received signal, we form an iterative blind deconvolution scheme, alternatively estimatin

Resolving mobility anisotropy in quasi-free-standing epitaxial graphene by terahertz optical Hall effect

In this work, we demonstrate the application of terahertz-optical Hall effect (THz-OHE) to determine directionally dependent free charge carrier properties of ambient-doped monolayer and quasi-free-standing-bilayer epitaxial graphene on 4H–SiC(0001). Directionally independent free hole mobility parameters are found for the monolayer graphene. In contrast, anisotropic hole mobility parameters with

Aerotaxy : gas-phase epitaxy of quasi 1D nanostructures

Cost- and resource-efficient growth is necessary for many applications of semiconductor nanowires. We here present the design, operational details and theory behind Aerotaxy, a scalable alternative technology for producing quality crystalline nanowires at a remarkably high growth rate and throughput. Using size-controlled Au seed particles and organometallic precursors, Aerotaxy can produce nanowi

Experimental and kinetic modeling study of NO formation in premixed CH4+O2+N2 flames

The nitric oxide (NO) formation in methane (CH4) flames has been widely investigated, with quite a few kinetic mechanisms available in the literature. However, studies have shown that there are often discrepancies between the simulations using various mechanisms and the experimental results. To elucidate reactions leading to these discrepancies, experiments were designed to measure the NO formatio

Plasma Metabolome and Circulating Vitamins Stratified Onset Age of an Initial Islet Autoantibody and Progression to Type 1 Diabetes : the TEDDY Study

Children's plasma metabolome, especially lipidome reflects gene regulation and dietary exposures, heralding the development of islet autoantibodies (IA) and type 1 diabetes (T1D). The TEDDY study enrolled 8676 newborns by screening HLA-DR-DQ genotypes at six clinical centers in four countries; profiled metabolome and measured concentrations of ascorbic acid, 25-hydroxyvitamin D (25(OH)D), erythroc

Urban cooling : Which façade orientation has the most impact on a microclimate?

Deploying solar reflective materials on urban surfaces is known as an effective heat mitigation strategy. Several studies have shown their cooling impacts; however, most of them have focused on rooftops rather than facades. The novelty of this paper is related to exploring the impact of each façade orientation on the corresponding microclimate and energy balance. High albedo materials were impleme

Governing the sharing economy : Towards a comprehensive analytical framework of municipal governance

The sharing economy is having a transformative impact on our cities, and many municipalities are facing a challenge – how to systematically engage with the sharing economy to both mitigate its negative and enhance its positive impacts. Academic understanding of municipal governance mechanisms of the sharing economy remains poor. To address this gap, we develop a comprehensive analytical framework

Tiden har runnit ikapp Sverige : Sju principer för god vattenstyrning och hantering

Vi vill med den här artikeln peka på att Sveriges städer har flera utmaningar kring styrning och hantering av vatten, samt föreslår sju principer för lösningar. Klimatförändringarna och den urbana tillväxten gör att åtgärder behövs nu för att hantera både vattenbrist och översvämning på ett integrerat sätt. Här fokuserar vi på kommunnivå och urbana områden, där vi argumenterar för att det behövs eWe argue in this paper that Swedish urban areas have several urgent challenges when it comes to water governance and we propose seven principles for addressing them. Climate change and urban growth call for swift action to manage both water scarcity and flooding in an integrated way. This paper focuses on the municipal level for which we argue that there is a need for a more systematic approach. T

Women’s Inclusion in the Malian Peace Negotiations: Norms and Practices

This article studies the implementation of the global norm of women’s inclusion in the Malian peace negotiations. It constructs a theoretical framework for analyzing practices of resistance, which object to the validity of the norm, and practices of refinement, which engage with the application of the norm. Based on interviews with women who attended the Malian peace negotiations it finds that wom

Cross-classified Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA) to evaluate hospital performance : the case of hospital differences in patient survival after acute myocardial infarction

OBJECTIVE: To describe a novel strategy, Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA) to evaluate hospital performance, by analysing differences in 30-day mortality after a first-ever acute myocardial infarction (AMI) in Sweden.DESIGN: Cross-classified study.SETTING: 68 Swedish hospitals.PARTICIPANTS: 43 247 patients admitted between 2007 and 2009, with a fi

Identification of Women at High Risk of Breast Cancer Who Need Supplemental Screening

Background Mammography screening reduces breast cancer mortality, but a proportion of breast cancers are missed and are detected at later stages or develop during between-screening intervals. Purpose To develop a risk model based on negative mammograms that identifies women likely to be diagnosed with breast cancer before or at the next screening examination. Materials and Methods This study was b

Metalinguistic relativity : Does one's ontology determine one's view on linguistic relativity?

Linguistic relativity is a notion that has been met with both praise and scorn. We argue that there is correlation between theorists’ general conceptions of the nature of language, and their stance toward linguistic relativity. Starting with the proponents of the thesis, we distinguish between the relativists of the early days (Boas, Whorf) and modern neo-Whofians (Levinson, Slobin), showing that

Flame retardancy of rigid polyurethane foams containing thermoregulating microcapsules with phosphazene-based monomers

Abstract: Thermoregulating microcapsules (MC) with flame-retardant properties were used to produce polyurethane (PU) foams. Thermogravimetric analyses of the microcapsules performed under atmospheric air and nitrogen confirmed that the hexa(methacryloylethylenedioxy) cyclotriphosphazene (PNC-HEMA) monomer raised the amount of residue after exposure to high temperature, proving the formation of a t

Subject-specific FE models of the human femur predict fracture path and bone strength under single-leg-stance loading

Hip fractures are a major health problem with high socio-economic costs. Subject-specific finite element (FE) models have been suggested to improve the fracture risk assessment, as compared to clinical tools based on areal bone mineral density, by adding an estimate of bone strength. Typically, such FE models are limited to estimate bone strength and possibly the fracture onset, but do not model t

”Gå eller rulla – Alla vill knulla!” : Funktionsrättsaktivism i nyliberala landskap

This study follows groups in Sweden that are involved in a political struggle to change norms regarding sexuality and disability. The groups are mostly connected to the disability movement or the movement of sexual politics. The following questions have guided the research process: How do the groups describe their activities? What strategies do they use? What relations can be identified between th

The role of location on complexity of firms’ innovation outcome

In this paper we analyze how the location of firms influences their innovation outcomes, particularly the complexity of the outcomes. Using three waves of the Community Innovation Survey in Sweden for a balanced panel of firms from 2006 to 2012, we identified a range of innovation outcome categories, i.e. simple and complex (low-, medium-, highly-complex). The backbone of such categorization is ba

Reinterpretation of LHC results for new physics: Status and recommendations after run 2

We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpretation Forum. We detail current experimental offerings in direct searches for new particles, measurements, technical implementations and Open Data, and provide a set of recommendations for further improving the presentati

Mesial temporal tau is related to worse cognitive performance and greater neocortical tau load in amyloid-β–negative cognitively normal individuals

We examined whether mesial temporal (Me) tau relates to cognitive performance in 47 amyloid-β (Aβ)-negative, cognitively normal older adults (>60 years old). Me-tau was measured using [18F]flortaucipir–positron emission tomography standardized uptake value ratio. The effect of continuous and categorical (stratified at standardized uptake value ratio = 1.2 [21% Me-positive]) Me-tau on cognition (mi

Predictors of health care practitioners’ normative attitudes and practices towards sexual and reproductive health and rights : a cross-sectional study of participants from low-income countries enrolled in a capacity-building program

Background: Sexual and Reproductive Health and Rights (SRHR) is a concept of human rights applied to sexuality and reproduction. Suboptimal access to SRHR services in many low-income countries results in poor health outcomes. Sustainable development goals (3.7 and 5.6) give a new impetus to the aspiration of universal access to high-quality SRHR services. Indispensable stakeholders in this process
