Atmospheric new particle formation (NPF) is an important phenomenon in terms of global particle number concentrations. Here we investigated the frequency of NPF, formation rates of 10 nm particles, and growth rates in the size range of 10–25 nm using at least 1 year of aerosol number size-distribution observations at 36 different locations around the world. The majo
Platinum(II) complexes of the type [Pt(thioether)2Cl]+(thioether = dimethyl sulfide, thioxane) are capable of abstracting a phenyl group from the BPh4 counterion with formation of trans[Pt(thioether)2ClPh] compounds. Thermal reactions proceed both in the solid phase and in nitromethane solution at elevated temperature and have preparative importance. Phenylation of the Pt(II) centre also occurs inPlatinum(II) complexes of the type [Pt(thioether)2Cl]+(thioether = dimethyl sulfide, thioxane) are capable of abstracting a phenyl group from the BPh4 counterion with formation of trans[Pt(thioether)2ClPh] compounds.

Factor IX is a vitamin K-dependent procoagulant zymogen of a serine protease. In the presence of Ca2+ the active form of factor IX (factor IXa beta) forms a complex with factor VIIIa on suitable phospholipid surfaces such as aggregated platelets. This macromolecular complex rapidly activates factor X. We have previously provided data that suggest an interaction between the NH2-terminal epidermal g
Prostate cancer is the most diagnosed cancer in men. The diagnosis is confirmed by pathologists based on ocular inspection of prostate biopsies in order to classify them according to Gleason score. The main goal of this paper is to automate the classification using convolutional neural networks (CNNs). The introduction of CNNs has broadened the field of pattern recognition. It replaces the classic
The effect of fuel ethanol content (10, 85 and 100 %) on primary emissions and on subsequent secondary aerosol formation was investigated for a Euro 5 flex-fuel gasoline vehicle. Emissions were characterized during a New European Driving Cycle (NEDC) using a comprehensive setup of high time-resolution instruments. A detailed chemical composition of the exhaust particulate matter (PM) was studied u
Air-starved combustion of biomass and fossil fuels releases aerosols, including airborne carbonaceous particles, causing negative climatic and health effects. Radiocarbon analysis of the elemental carbon (EC) fraction can help apportion sources of its emission, which is greatly constrained by the challenges in isolation of EC from organic compounds in atmospheric aerosols. The isolation of EC usin
Time-resolved particle emissions from a conventional wood stove were investigated with aerosol mass spectrometry to provide links between combustion conditions, emission factors, mixing state of refractory black carbon and implications for organic tracer methods. The addition of a new batch of fuel results in low temperature pyrolysis as the fuel heats up, resulting in strong, short-lived, variabl
We have prepared electrodes for photo-electro-chemical cells which have enabled to pre-charge colloidal quantum dots in well-controlled fashion. Femtosecond transient absorption measurements were carried out revealing clear speed-up of the photo-induced charge carrier dynamics, particularly the recombination. Such studies allow to understand the behavior of light harvesting materials in operationa
We investigated the risk of developing anastomotic stenosis after radical prostatectomy and found it to be twice as high after open surgery as after robot-assisted prostatectomy. The risk seems to be associated with the number of sutures/takes in the anastomosis.
Portfolio optimization involves a tradeoff between maximizing expected returnand minimizing risk. In practice, useful formulations also include various costs and constraints that regularize the problem and reduce the risk due to estimation errors, resulting in solutions that depend on a number of hyperparameters. As the number of hyperparameters grows, selecting their value becomes increasingly imPortfolio selection involves a trade-off between maximizing expected return and minimizing risk.

The aim of this study was to investigate mental health and emotion regulation strategies of unaccompanied asylum-seeking children and adolescents. A survey was conducted, using questionnaires that also contained queries regarding the participants’ belief of the future. A total of 95 boys in the ages of 13 to 17 years old, living in seven refugee housing facilities, answered the questionnaire “The
Over the last few decades the increase in globalised trade has forced industrial companies all over the world to undergo major organisational reconstruction work, specifically in areas such as logistics and transport. Activities, that used to be managed within the company business model, are being outsourced to third parties to achieve flexibility and more efficient cost management systems. In tod
Avancerad användning av glas som konstruktionsmaterial i pelare och balkar har blivit allt vanligare de senaste åren. Detta arbete redogör för vilka metoder och normer som kan användas för att dimensionera glasbalkar i bärande konstruktioner och vilken typ av glasbalk som är lämpligast ur hållfasthets och säkerhets synpunkt. Tidigare har glaset mest använts i fönster där det inte har haft en bäran
Many people and organizations across the globe work towards a sustainable future. Artificial intelligence (AI) can be a powerful tool in their efforts.AI technologies, which aim to imitate the natural intelligence of humans and animals, have made enormous progress in the past decade. AI has brought us a whole range of futuristic tools — from self-driving cars to virtual assistants, smart home appl
The aim of this study was to establish traceable number concentration measurements of airborne particles beyond 10 μm in particle size. To this end, the primary standards for particle number concentration at the National Metrology Institutes of Switzerland and Japan were further developed to extend their measurement capabilities. Details on the upgraded setup are provided. An inter-comparison of t
Background: Artificial intelligence (AI) systems can potentially aid the diagnostic pathway of prostate cancer by alleviating the increasing workload, preventing overdiagnosis, and reducing the dependence on experienced radiologists. We aimed to investigate the performance of AI systems at detecting clinically significant prostate cancer on MRI in comparison with radiologists using the Prostate Im
It is generally known that, unlike structured proteins, intrinsically disordered proteins, IDPs, exhibit various structures and conformers, the so-called conformational ensemble, CoE. This study aims to better understand the conformers that make up the IDP ensemble by decomposing the CoE into groups separated by their radius of gyration, Rg. A common approach to studying CoE for IDPs is to use low
Introduction Severe osteogenesis imperfecta (OI) is a debilitating disease with no cure or sufficiently effective treatment. Mesenchymal stem cells (MSCs) have good safety profile, show promising effects and can form bone. The Boost Brittle Bones Before Birth (BOOSTB4) trial evaluates administration of allogeneic expanded human first trimester fetal liver MSCs (BOOST cells) for OI type 3 or severe
