In this paper the machinery of Hybrid Logic and the logic of public announcements are merged. In order to bring the two logics together properly the underlying hybrid logic has been changed such that nominals only partially denote states. The hybrid logic contains nominals, satisfaction operators, the downarrow binder as well as the global modality. Following this, an axiom system for the Hybrid P
A wireless body area network (WBAN) is a network of compact low power devices that are either wearable or implantable. A compact antenna with suitable radiation pattern and polarization is useful for WBAN applications. Ultra-Wideband (UWB) technology can be used in WBAN applications that require high data rates. This paper present a small wearable (15x17x17 mm) UWB antenna designed and optimized i
The paper describes a debris-free, efficient laser-produced plasma source emitting EUV radiation. The source is based on a double-stream Xe/He gas-puff. Its properties and spectroscopic signatures are characterized and discussed. The spatio-spectral features of the EUV emission are investigated. We show a large body of results related to the intensity and brightness of the EUV emission, its spatia
The use of asymmetric transfer hydrogenation combined with dynamic kinetic resolution for the synthesis of β-hydroxy-α-(tert-butoxycarbonyl)amino esters in water is described. This procedure provides the desired amino alcohols in good yields, diastereoselectivities, and enantioselectivities. A surfactant is employed to achieve good yields due to the hydrophobic nature of both the catalyst and subs
5-Aminolevulinic acid (ALA) is a common biosynthetic intermediate of both chlorophyll and heme. Glutamyl-tRNAGlu reductase, encoded by the hemA gene, is the initial enzyme of ALA biosynthesis. The presence of several hemA genes provides a possible explanation to the ability of plants to meet the different requirement of chlorophyll and heme using a common biosynthetic pathway. In this work, two ba
The focus of the thesis is on chemically cross-linked hydrogels which drastically change their volume when immersed in solutions of different ionic surfactants (with or without added salt). The two main questions addressed are: (1) How useful are simple gel swelling experiments to the study of polymer-surfactant interactions?, and (2) How does the volume of a cross-linked polymer gel change when i
The so-called Glires hypothesis postulates a sister-group relationship between Rodentia (e.g., rat and mouse) and Lagomorpha (e.g., rabbit). Recent molecular phylogenetic analyses have yielded incongruent results, and either supported or refuted the Glires grouping. In order to study this inconsistency we have reconstructed phylogenetic trees based on data sets of 20 orthologous nuclear protein co
The way the fuel is introduced into the combustion chamber is one of the most important parameters for the power output and the generation of emissions in the combustion of liquid fuels. The interaction beween the turbulent gas flow field and the liquid fuel droplets, the vaporisation of them and the mixing of the gaseous fuel with the ambient air that are vital parameters in the combustion proces
The paper presents Jitterbug, a Matlab-basedtoolbox for real-time control performance analysis. The controlsystem is described using a number of connected continuous-time anddiscrete-time linear systems. The control performance is measured bya continuous-time quadratic cost function. A stochastic executionmodel is used to describe when the different discrete-time systemsare updated during the cont
Objectives Studies on health effects of tobacco often rely on self-reported exposure data, which is subjective and can lead to misclassification. The aim of this study was to describe the prevalence of cigarette smoking, snus and e-cigarette use, as well as to validate self-reported tobacco use among young adults in Sweden. Method Participants of a population-based Swedish cohort (n=3052), aged 22
A major issue in Irish economic history is the lack of national accounts before the interwar period. This paper constructs new annual estimates of real GDP between 1842 and 1913 based on a novel two-stage econometric approach. Our results show that while living standards approximately tripled in this period, development was uneven with contractions in economic activity not only during the Great FaA major issue in Irish economic history is the lack of national accounts before the interwar period.

Whilst critical realism (CR) is becoming recognised as a significant meta-theory for the social sciences, there is little guidance on how to produce research which is consistent with its ontological and epistemological assumptions. This article contributes to an emerging discussion about how CR can be applied, drawing on an example of a qualitative study that has sought to understand and explain t
To meet the ever increasing demand for computational speed and use of ever larger datasets, multi GPU installations look very tempting. Lunarc and the Theoretical Astrophysics group at Lund Observatory collaborate on a pilot project to evaluate and utilize multi-GPU architectures for scientific calculations. Starting with a small workshop in 2009, continued investigations eventually lead to the pr
Our aim was to identify a cut-off value for self-reported, abnormal cold sensitivity and to identify cold sensitivity predictors after hand injuries. The Cold Intolerance Symptom Severity (CISS) questionnaire and a VAS question concerning discomfort on exposure to cold were investigated in 94 normal people and 88 patients. A CISS score >450 was defined as abnormal cold sensitivity. Multiple injure
