Background: Spirometry reference values differ by race/ethnicity, which is controversial. We evaluated the effect of race-specific references on prevalence of lung function impairment and its relation to breathlessness and mortality in the US population. Methods: Population-based analysis of the National Health and Nutrition Examination Survey (NHANES) 2007–2012. Race/ethnicity was analyzed as bla
Activation functions play a central role in deep learning since they form an essential building stone of neural networks. In the last few years, the focus has been shifting towards investigating new types of activations that outperform the classical Rectified Linear Unit (ReLU) in modern neural architectures. Most recently, rational activation functions (RAFs) have awakened interest because they w
Many hand-held or mixed reality devices are used with a single sensor for 3D reconstruction, although they often comprise multiple sensors. Multi-sensor depth fusion is able to substantially improve the robustness and accuracy of 3D reconstruction methods, but existing techniques are not robust enough to handle sensors which operate with diverse value ranges as well as noise and outlier statistics
There exist several datasets for developing self-driving car methodologies. Manually collected datasets impose inherent limitations on the variability of test cases and it is particularly difficult to acquire challenging scenarios, e.g. ones involving collisions with pedestrians. A way to alleviate this is to consider automatic generation of safety-critical scenarios for autonomous vehicle (AV) te
The phase gradient autofocus (PGA) is a robust autofocusing approach that can efficiently refocus defocused synthetic aperture radar (SAR) imagery produced by frequency-domain algorithms. However, from a conventional viewpoint, PGA cannot be extended to refocus SAR imagery produced by time-domain algorithms, such as the filtered backprojection (FBP), as the spectrum of the FBP imagery is range amb
We present the first results of K2-OjOS, a collaborative project between professional and amateur astronomers primarily aimed to detect, characterize, and validate new extrasolar planets. For this work, 10 amateur astronomers looked for planetary signals by visually inspecting the 20 427 light curves of K2 campaign 18 (C18). They found 42 planet candidates, of which 18 are new detections and 24 ha
Loss of soil organic carbon (SOC) from farmland is a key threat to the capacity of soils to provide ecosystem services and exacerbates climate change. In alignment with a published protocol, we conducted a review and meta-analysis of time series of SOC measurements in long-term agricultural experiments to study absolute SOC changes under different agricultural management regimes. Our results show
I denna avhandling undersöks opinionsundersökningens introduktion i Sverige under mitten av 1900-talet. Fokus ligger på Svenska Gallupinstitutet AB, som 1941 etablerades som landets första opinionsinstitut och som introducerade den urvalsbaserade enkätundersökningen som ett nytt medium genom vilket den allmänna opinionen kunde representeras. De hade i princip monopol på området till 1950-talets miThis thesis examines the introduction and impact of opinion polling in Sweden during the mid-twentieth century, focusing on the activities of the Swedish Gallup Institute (Svenska Gallupinstitutet). Established in 1941 as the country’s first polling organization, the institute introduced sample surveys as a new means of representing public opinion and had a near-monopoly on polling until its decli
Background: Patients with diabetes admitted to emergency care face a higher risk of complications, including prolonged hospital stays, admissions to the intensive care unit and mortality. Aim: To develop a machine learning (ML) model to predict 30-day mortality in patients with diabetes admitted to the emergency department (ED). Design and setting: A cohort study utilizing data from all nine ED’s
Nepal has made major progress in expanding its national electricity grid, creating the potential for a double transition as increased access to electricity benefits the energy-poor while setting the infrastructural ground for a transition to renewable energy sources. However, despite increased access, many households in Nepalcontinue to rely on traditional and transition fuels such as firewood and
Litter decomposition is a source of gaseous products, including volatile organic compounds (VOCs) to the atmosphere. The quantity and the chemical composition of the VOC blends released from litter vary between plant species and depend on environmental factors and litter microbial communities. Here, we assessed VOC release from decomposing litter in a 3-year incubation conducted in a climate manip
Randomised controlled trial (RCT) protocols contain essential details needed to understand and evaluate the trial's planned aims, design, data collection methods, monitoring, data analysis, and participants' safety. However, key information is often omitted from paediatric RCT protocols, including details on dose adjustments of interventions based on age, body surface area, or weight; developmenta
In this country report, as well as the accompanying general report, the authors revisit a 1999 European Taxation article discussing tax avoidance, which stemmed from the first European Association of Tax Law Professors meeting. The authors explore shifts in tax avoidance perception due to the introduction of the treaty general anti-avoidance rule (GAAR) (principal purpose test), EU GAAR and specif
Scholarship in peace and conflict studies is paying increasing attention to the role of the environment for conflict transformation and peacebuilding. However, a closer analysis on how different understandings of “nature” implicate policy proposals and approaches to peacebuilding is lacking. In this study, we provide a critical reflection on the diverse understandings and valuations of nature at t
In this paper, we describe the conversion of a heart trans- plantation dataset in the RDF format and its application in a survival prediction program. The International Society for Heart & Lung Trans- plantation (ISHLT) maintains a registry of heart transplantations that it gathers from operations performed worldwide. The US United Net- work for Organ Sharing (UNOS) and the Scandinavian Scandi
For theologians such as Karl Barth the support for Germany’s militaristic ambitions and actions voiced in the manifesto "An die Kulturwelt", published in 1914, was a consequence of the historicization of theology. Ernst Troeltsch (1865-1923), whose interdisciplinary thinking revolved around the significance of history for theology, was labeled the theologian of historicism. Although he had not sig
Drawing on collective experience from ten collaborative research projects focused on the Global South, we identify three major challenges that impede the translation of research on sustainability and resilience into better-informed choices by individuals and policy-makers that in turn can support transformation to a sustainable future. The three challenges comprise: (i) converting knowledge produc
Background: Well-developed vocabulary skills are crucial for academic success. Students having the language of instruction as a second language and students from lower socioeconomic backgrounds often have lower performance on vocabulary assessments. Teachers play an important role in supporting the vocabulary development of all students, regardless of background and educational needs.Aims: To inve
