Characterizing uncertainties in atmospheric inversions of fossil fuel CO2 emissions in California

Atmospheric inverse modelling has become an increasingly useful tool for evaluating emissions of greenhouse gases including methane, nitrous oxide, and synthetic gases such as hydrofluorocarbons (HFCs). Atmospheric inversions for emissions of CO2 from fossil fuel combustion (ffCO2) are currently being developed. The aim of this paper is to investigate potential errors and uncertainties related to

Comparison of four inverse modelling systems applied to the estimation of HFC-125, HFC-134a, and SF6 emissions over Europe

Hydrofluorocarbons (HFCs) are used in a range of industrial applications and have largely replaced previously used gases (CFCs and HCFCs). HFCs are not ozone-depleting but have large global warming potentials and are, therefore, reported to the United Nations Framework Convention on Climate Change (UNFCCC). Here, we use four independent inverse models to estimate European emissions of the two HFCs

Co-Creative Knitting : explorations of an improvisational practices

This proposal addresses the profile area: Art, Technology, Materiality, by focusing on discussions of the nature of the materiality of artistic practice and its implications. The proposal considers the interplay between making and thinking, encompassing both the human and the non-human, resulting in co-constructed knowledge and meaning through performative and textile practices. This performative

Morganella morganii bloodstream infection affects the elderly in close contact with healthcare

BackgroundWe aimed to fill the gaps of knowledge concerning incidence rates and temporal trend, clinical features and risk factors for death for M. morganii bloodstream infections in south Sweden.MethodsThis was an observational, population-based study including all patients with at least one blood culture positive for Morganella morganii between 2013-2023 in Skåne, south Sweden.ResultsA total of

Pandrug-resistant Klebsiella pneumoniae isolated from Ukrainian war victims are hypervirulent

OBJECTIVES: Carbapenem- and colistin-resistant Klebsiella pneumoniae were isolated from war victims treated in hospitals in Ukraine. The question was whether these pandrug-resistant K. pneumoniae are pathogenic and capable of causing disease in a broader context.METHODS: Klebsiella pneumoniae clinical isolates (n = 37) were tested for antibiotic resistance and subjected to whole-genome sequencing

Low-Complexity Channel Estimation and Localization with Random Beamspace Observations

We investigate the problem of low-complexity, high-dimensional channel estimation with beamspace observations, for the purpose of localization. Existing work on beamspace ESPRIT (estimation of signal parameters via rotational invariance technique) approaches requires either a shift-invariance structure of the transformation matrix, or a full-column rank condition. We extend these beamspace ESPRIT

Lyckat experiment banar väg för nytt grundämne

Scientists have found an alternative way to produce atoms of the superheavy element livermorium. The new method opens up the possibility of creating another element that could be the heaviest in the world so far: number 120.

Antihistamine use and osteoarthritis or joint pain

Objectives: Antihistamines have been reported to be linked with less pain in osteoarthritis. We aimed to estimate associations between antihistamine use and three outcomes: prevalent osteoarthritis, current joint pain, and developing osteoarthritis. Methods: We included 25 003 participants of EpiHealth – a cohort of persons aged 45 to 75 from Malmö/Uppsala in Sweden. Participants self-reported the

Two-Phase Fluid Dynamics in Proton Exchange Membrane Fuel Cells : Counter-Flow Liquid Inlets and Gas Outlets at the Electrolyte-Cathode Interface

Understanding the counter-flow of liquid inlet and gas outlet at the interface between the electrolyte and cathode gas diffusion layer (GDL) is crucial for water management in proton exchange membrane fuel cells. Existing studies typically overlook air outlets and assume a fixed liquid inlet direction. This study uses a volume of fluid method to model two-phase interactions in a T-shaped GDL and g

Longitudinal assessment of the impact of prevalent diabetes on hospital admissions and mortality in the general population: a prospective population-based study with 19 years of follow-up

BackgroundHospitalization indicates the presence of severe disease and constitutes a leading cost in health care. We aimed to prospectively assess if prevalent diabetes mellitus contributes to excess all-cause and cause-specific hospital admissions and mortality at the population level.MethodsWe used a Swedish prospective population-based cohort, including 25,642 individuals of whom 4.2% had preva

Fueling radical and renewable innovations? An analysis of public innovation funding in Sweden, 1970-2021

In the face of climate change, governments are scaling up public investments in mitigation efforts and green technologies. However, critics question the ability of public funding agencies to promote the most promising innovations. This paper contributes to this debate by presenting a long-term database, that directly links Swedish innovations to public funding between 1970 and 2021. We use logisti

Exploring Artificial Intelligence in Emergency Medicine for Predicting Disposition, Death, and Diagnosis

In the emergency department (ED), physicians and nurses make rapid, critical decisions. With the advancement of artificial intelligence (AI), we aimed to explore whether AI decision support could offer clinical benefits in the ED. Paper I: This study found no correlation between ED hospital admission likelihood and in-hospital bed occupancy levels, suggesting that previous findings may vary acrossIn the emergency department (ED), physicians and nurses make rapid, critical decisions.

Concentrations of glutamate and N-acetylaspartate detected by magnetic resonance spectroscopy in the rat hippocampus correlate with hippocampal-dependent spatial memory performance

Magnetic resonance spectroscopy (MRS) has been employed to investigate brain metabolite concentrations in vivo, and they vary during neuronal activation, across brain activity states, or upon disease with neurological impact. Whether resting brain metabolites correlate with functioning in behavioral tasks remains to be demonstrated in any of the widely used rodent models. This study tested the hyp

Evidence of a recent decline in UK emissions of hydrofluorocarbons determined by the InTEM inverse model and atmospheric measurements

National greenhouse gas inventories (GHGIs) are submitted annually to the United Nations Framework Convention on Climate Change (UNFCCC). They are estimated in compliance with Intergovernmental Panel on Climate Change (IPCC) methodological guidance using activity data, emission factors and facility-level measurements. For some sources, the outputs from these calculations are very uncertain. Invers

Inverse modelling of CF4 and NF3 emissions in East Asia

Decadal trends in the atmospheric abundances of carbon tetrafluoride (CF4) and nitrogen trifluoride (NF3) have been well characterised and have provided a time series of global total emissions. Information on locations of emissions contributing to the global total, however, is currently poor. We use a unique set of measurements between 2008 and 2015 from the Gosan station, Jeju Island, South Korea

History of chemically and radiatively important atmospheric gases from the Advanced Global Atmospheric Gases Experiment (AGAGE)

We present the organization, instrumentation, datasets, data interpretation, modeling, and accomplishments of the multinational global atmospheric measurement program AGAGE (Advanced Global Atmospheric Gases Experiment). AGAGE is distinguished by its capability to measure globally, at high frequency, and at multiple sites all the important species in the Montreal Protocol and all the important non

Global and regional emissions estimates of 1,1-difluoroethane (HFC-152a, CH3CHF2) from in situ and air archive observations

High frequency, in situ observations from 11 globally distributed sites for the period 1994-2014 and archived air measurements dating from 1978 onward have been used to determine the global growth rate of 1,1-difluoroethane (HFC-152a, CH3CHF2). These observations have been combined with a range of atmospheric transport models to derive global emission estimates in a top-down approach. HFC-152a is
