An algorithm is presented in which the Colour-Dipole Cascade Model as implemented in the Ariadne program is corrected to match the fixed order tree-level matrix elements for e e(+) --> n jets. The result is a full parton level generator for e e(+) annihilation where the generated states are correct on tree-level to fixed order in alpha(s) and to all orders with modified leading logarithmic (MLLA)
We perform a detailed study of the sources of perturbative uncertainty in parton-shower predictions within the Herwig 7 event generator. We benchmark two rather different parton-shower algorithms, based on angular-ordered and dipole-type evolution, against each other. We deliberately choose leading order plus parton shower as the benchmark setting to identify a controllable set of uncertainties. T
We develop a Lyapunov-based analysis of Korpelevich’s extragradient method and show that it achieves an o(1/k) last-iterate convergence rate of the constructed Lyapunov function. This Lyapunov function simultaneously upper bounds several standard measures of optimality, which allows our analysis to sharpen existing last-iterate convergence guarantees for these measures. Moreover, the same analysis
An application of a flexible polyvinylimidazole osmium functionalised polymer for efficient electrical wiring of whole Gluconobacter oxydans cells is described. The performance of the redox polymer as a mediator for intact bacterial cells was tested with glucose, ethanol and glycerol, typical substrates of the periplasmically localised PQQ-dependent membrane bound dehydrogenases. The efficiency of
The development of models that provide accurate spatio-temporal predictions of ambient air pollution at small spatial scales is of great importance for the assessment of potential health effects of air pollution. Here we present a spatio-temporal framework that predicts ambient air pollution by combining data from several different monitoring networks and deterministic air pollution model(s) with
The Anna Lindh Lecture 2016 6 October 2016 Business and Human Rights – Can Business Meet the Challenge? By Anne Ramberg Vice-Chancellor Director Your Excellencies Ladies and gentlemen Students Dear friends, I want to thank the Raoul Wallenberg Institute for having invited me to give this year’s Anna Lindh lecture. I am deeply honoured. Raoul Wallenberg, a businessman, as we all know saved tens of

The emergence of the Faster-Than-Nyquist signaling (FTN) technology has im- proved the tight spectrum resources by compressing the transmission interval between adjacent pulses. In a natural environment, data transmission via a wire- less medium and through multi-path, at a high data rate, the leakage of these paths among symbols can cause severe inter-symbol interference (ISI). In order to compen
The inability of organisations to develop successfully and their lack of a holistic view and of relevant quantitative facts are factors that played a major role in my choice of a research area for this and my licentiate thesis (Ljungberg, 1994). These two theses together represent the work conducted for the PhD degree. There is a strong need in this research area for increased insight into the de
The electron kinetics in nanowire-based hot-carrier solar cells is studied, where both relaxation and extraction are considered concurrently. Our kinetics is formulated in the many-particle basis of the interacting system. Detailed comparison with simplified calculations based on product states shows that this includes the Coulomb interaction both in lowest and higher orders. While relaxation rate
A multi-stage assembly network is considered. A number of end items should be delivered at a certain time. Otherwise a delay cost is incurred. End items and components that are delivered before they are needed will cause holding costs. All operation times are independent stochastic variables. The objective is to choose starting times for different operations in order to minimize the total expected
Addressing the need for modulated spin configurations is crucial, as they serve as the foundational building blocks for next-generation spintronics, particularly in atomically thin structures and at room temperature. In this work, we realize intrinsic ferromagnetism in monolayer flakes and tunable ferro-/antiferromagnetism in (Fe0.56Co0.44)5GeTe2 antiferromagnets. Remarkably, the ferromagnetic ord

Structural properties of encapsidated flexible polyelectrolytes in viral capsids with dodecahedral charge distribution have been investigated by Monte Carlo simulations using a coarse-grained model. Several capsid charge distributions ranging from a homogeneous surface charge distribution (lambda=0) to a complete dodecahedral distribution (lambda=1) at constant total capsid charge and fixed radial
The dynamic mechanical properties and acoustic damping of polyurethane (PU) foams loaded with a hyperbranched polymer (HBP) have been studied. The results show a significant modulus enhancement parallel to an increased vibration damping in the low frequency range of approximate to 1 Hz with increased amount of HBP. Furthermore, an increased acoustic damping in the frequency interval of 500-1600 Hz
