Generalized Frequency Division Multiplexing (GFDM) is a recent multi carrier modulation technique that can provide low out-of-band radiation, which makes it an attractive choice for the PHY layer of cognitive radios operating in fragmented TV white spaces. Primary, incumbent signals can now be protected with a geo-location database query mechanism. Even then, sensing opportunistic users (OU) opera

ZnO nanowires were grown on Ag wire with a diameter of similar to 250 mu m and used in an electrochemical sensor. The enzyme glucose oxidase (GOD) was immobilized on the ZnO nanowires, and the Ag wire was connected directly to the gate of a MOSFET. Upon exposure to glucose (1-100 mu M), the electrochemical response from the GOD induced a stable measurable voltage change on the gate leading to a st

Popular Abstract in Swedish Kontrakt som handlas på de internationella finans- och råvarumarknaderna är förenade med komplexa riskstrukturer. Denna avhandling behandlar två specifika typer av risk; marknadsrisk och kreditrisk. Det första kapitlet i avhandlingen undersöker marknadsrisker på den Nordiska elmarknaden. Vi utför in-sample och out-of-sample backtesting av en VaR-modell baserad på GARCContracts traded on international financial and commodity markets are associated with complex risk structures. In this dissertation we are concerned with two specific types of risks; market risks and credit risks. The first chapter investigates market risks in the context of the Nordic electricity market. The paper performs in- and out-of-sample backtesting of a VaR model based on GARCH volatili

Popular Abstract in English Mobile communication systems are now evolving towards the fifth generation (5G). In the near future, we expect an explosive increase in the number of connected devices, such as phones, tablets, wearable accessories, sensors, connected vehicles and so on. We can imagine that much higher data rates than in today's 4G systems are required. Sounds like the future of communiMobile communications are now evolving towards the fifth generation (5G). In the near future, we expect an explosive increase in the number of connected devices, such as phones, tablets, sensors, connected vehicles and so on. Much higher data rates than in today's 4G systems are required. In the 5G visions, better coverage in remote regions is also included, aiming for bringing the current "4 bill

Automation, in terms of systems such as adaptive/active cruise control (ACC) or collision warning systems, is increasingly becoming a part of everyday driving. These systems are not perfect though, and the driver has to be prepared to reclaim control in situations very similar to those the system easily handles by itself. This paper uses a questionnaire answered by 130 ACC users to discuss future

The unimolecular chemiluminescent decomposition of unsubstituted dioxetanone was studied at the complete active space self-consistent field level of theory combined with the multistate second-order multiconfigurational perturbation theory energy correction. The calculations revealed interesting features. Two transition states, two conical intersections, and one intermediate stable biradical struct

Objectives: Does thrombin activation seen in patients with abdominal aortic aneurysms (AAA) relate to the thrombus surface area or volume within the aneurysm? Patients and methods: A total of 130 patients with AAA were analyzed regarding levels of the complex between activated protein C-protein C inhibitor (APC-PCI) and AAA morphology. Analysis of APC-PCI complex was made using a sandwich immunofl

Dataflow descriptions are a natural match to application areas such as signal processing, cryptography, networking, image processing, and media coding. This paper addresses the problem of efficiently executing the basic elements of a dataflow program, its actors, written in a language such as MPEG's RVC-CAL. Using actor machines as an execution model for dataflow actors, we devise a metric for mea

BACKGROUND: & aims: Young individuals with exocrine pancreatic insufficiency (EPI) show growth reduction that can be reversed by dietary pancreatic enzyme supplementation. Here we investigated whether feeding an elemental diet could replace the growth-promoting effect of enzyme supplementation in EPI pigs. METHODS: Weaned pigs with intact pancreas (control) or pancreatic duct-ligated (EPI pigs

Study I: Thirteen patients underwent a modified Ross operation in which the free-standing pulmonary autograft was supported externally by a Dacron vascular prosthetic jacket (DVPJ). The tailor-made DVPJ prevented dilatation of the neo-aortic root significantly following a median follow-up of 47 months compared to a cohort of l3 matched patients undergoing conventional Ross operation. Study II: A

In nature, the same biochemical reaction can be catalyzed by enzymes having fundamentally different folds, reaction mechanisms and origins. For example, the third step of the reductive catabolism of pyrimidines, the conversion of N-carbamyl-beta-alanine to beta-alanine, is catalyzed by two beta-alanine synthase (beta ASase, EC 3.5.1.6) subfamilies. We show that the "prototype" eukaryote beta ASase

The emergence of post-genomic approaches that couple chromatin immunoprecipitation (ChIP) assays to high-throughput technique has greatly advanced our ability to investigate epigenetic features associated with normal cell development and disease. Nevertheless, these techniques exhibit some limitations. Firstly, standard protocols usually require millions of cells, thus limiting their application t

Objective: Quality improvement initiatives in emergency medicine (EM) often suffer from a lack of benchmarking data on the quality of care. The objectives of this study were twofold: 1. To assess the feasibility of collecting benchmarking data from different Swedish emergency departments (EDs) and 2. To evaluate patient throughput times and inflow patterns. Method: We compared patient inflow patte
