Volcanic eruptions contribute to climate variability, but quantifying these contributions has been limited by inconsistencies in the timing of atmospheric volcanic aerosol loading determined from ice cores and subsequent cooling from climate proxies such as tree rings. Here we resolve these inconsistencies and show that large eruptions in the tropics and high latitudes were primary drivers of inte
The assumption that voters systematically defend the welfare state is challenged by recent research showing that parties are on average not punished and sometimes even rewarded for welfare state retrenchment. We work to understand better the micro-foundations for this finding of non-punishment by exploring individuals’ preferences over social policy. In particular, we distinguish general support f
The oxygen-atom transfer reaction catalyzed by the mononuclear molybdenum enzyme dimethyl sulfoxide reductase (DMSOR) has attracted considerable attention through both experimental and theoretical studies. We show here that this reaction is more sensitive to details of quantum mechanical calculations than what has previously been appreciated Basis sets of at least triple-zeta quality are needed to
The weighted Weiss conjecture states that the system theoretic property of weighted admissibility can be characterized by a resolvent growth condition. For positive weights, it is known that the conjecture is true if the system is governed by a normal operator; however, the conjecture fails if the system operator is the unilateral shift on the Hardy space (discrete time) or the right-shift semigro
L-DOPA-induced dyskinesia is a major problem in the treatment of Parkinson's disease. Today there are few anti-dyskinetic treatments available for the patients, and all of them have major limitations. Recent findings have revealed an important role of the serotonin system in L-DOPA-induced dyskinesia. In the parkinsonian brain, serotonin axon terminals can compensate for the dopamine loss by conve
In Europe, 6,000 young people die of cancer yearly, the commonest disease causing death beyond the age of 1 year. In addition, 300,000-500,000 European citizens are survivors of a childhood cancer and up to 30% of them have severe long-term sequelae of their treatment. Increasing both cure and quality of cure are the two goals of the European paediatric haematology/oncology community. SIOPE coordi
Ensembles of (J,K)-regular low-density parity-check convolutional (LDPCC) codes are known to be asymptotically good, in the sense that the minimum free distance grows linearly with the constraint length. In this paper, we use a protograph-based analysis of terminated LDPCC codes to obtain an upper bound on the free distance growth rate of ensembles of periodically time-varying LDPCC codes. This bo
Tri-methyl-indium (TMI) is used as an indium transport molecule to introduce indium atoms to reactive hot gas flows/combustion environments for spectroscopic diagnostics. A seeding system was constructed to allow the addition of an inert TMI laden carrier gas into an air/fuel mixture burning consequently on a burner. The amount of the seeded TMI in the carrier gas can be readily varied by controll
This work proposes and demonstrates an acoustic trapping system where the trapping frequency is automatically determined and can be used to analyse changes in the acoustic trap. Critical for the functionality of this system is the use of a kerfed transducer that removes spurious resonances. This makes it possible to determine the optimal trapping frequency by analysing electrical impedance. It is
To elucidate the molecular requirements for cancer cell internalization of the extracellular cysteine protease inhibitor cystatin C, 12 variants of the protein were produced and used for uptake experiments in MCF-7 cells. Variants with alterations in the cysteine cathepsin binding region ((Δ1-10)-, K5A-, R8G-, (R8G,L9G,V10G)-, (R8G,L9G,V10G, W106G)-, and W106G-cystatin C) were internalized to a ve
Abstract in UndeterminedVehicular communication channels are characterized by a nonstationary time-frequency-selective fading process due to rapid changes in the environment. The nonstationary fading process can be characterized by assuming local stationarity for a region with finite extent in time and frequency. For this finite region, the wide-sense stationarity and uncorrelated scattering assum
Forest carbon cycles play an important role in efforts to understand and mitigate climate change. Large amounts of carbon (C) are stored in deep mineral forest soils, but are often not considered in accounting for global C fluxes because mineral soil C is commonly thought to be relatively stable. We explore C fluxes associated with forest management practices by examining existing data on forest C
This paper presents a new Hardware (HW) im- plementation proposal for Discrete Fourier Transform (DFT) based channel estimators. The presented algorithm uses the high time correlation property of the channel estimates to reduce the complexity and the power consumption by utilizing a lower number of bits for the FFT in the channel estimator, compared to a traditional approach. The idea is that the
Socialization is an undertheorized concept representing a challenge to constructivist approaches to European integration. Although references to the capacity of international institutions to shape actor preferences are common, the processes through which actors are thought to be socialized are not yet specified within the field. Once resolved, this challenge will turn out to strengthen the constru
