Temporal Trends of Stroke Epidemiology in Southern Sweden : A Population-Based Study on Stroke Incidence and Early Case-Fatality

Background: Up-to-date epidemiological stroke studies are important for healthcare planning and evaluating prevention strategies. This population-based study investigates temporal trends in stroke incidence and case-fatality in southern Sweden. Methods: First-ever stroke cases in the local catchment area of Skåne University Hospital in Lund, Sweden, between March, 2015 and February, 2016, were inc

Accurate and Efficient Evaluation of Characteristic Modes

A new method to improve the accuracy and efficiency of CM decomposition for perfectly conducting bodies is presented. The method uses the expansion of the Green dyadic in spherical vector waves. This expansion is utilized in the MoM solution of the EFIE to factorize the real part of the impedance matrix. The factorization is then employed in the computation of CM, which improves the accuracy as we

Digital Predistortion for Hybrid MIMO Transmitters

This article investigates digital predistortion (DPD) linearization of hybrid beamforming large-scale antenna transmitters. We propose a novel DPD processing and learning technique for an antenna sub-array, which utilizes a combined signal of the individual power amplifier (PA) outputs in conjunction with a decorrelation-based learning rule. In effect, the proposed approach results in minimizing t

Effect of Ge autodoping during III-V MOVPE growth on Ge substrates

During the MOVPE growth of III-V layers on Ge substrates, Ge atoms can be evaporated or etched from the back of the wafer and reach the growth surface, becoming incorporated into the epilayers. This is the so-called Ge autodoping effect, which we have studied through a set of growth experiments of GaInP and Ga(In)As layers lattice matched to Ge substrates, which have been characterized by Secondar

Survival after PICU admission : The impact of multiple admissions and complex chronic conditions

Objective Factors predicting survival over time after pediatric intensive care unit (PICU) admissions are not fully understood. The primary aim of the current study was to investigate whether multiple admissions (MADM) compared to single PICU admissions (SADM) were associated with poor survival over time after being admitted to PICU facilities. Our secondary aim was to investigate if the presence

Family symmetries and radiative corrections in multi-scalar extensions of the Standard Model

Människans vilja att förstå universums mest fundamentala byggstenar och dess naturlagar är den drivkraft som ligger till grund för elementarpartikelfysiken. Den teoretiska forskningen inom detta område vägleds idag till stor del av data från LHC-experimentet utanför Genève (LHC förkortar `Large Hadron Collider', dvs.~den Stora Hadronacceleratorn). Vid LHC accelereras protoner till extremt höga hasThe four articles contained in this thesis all concern aspects of model building beyond the Standard Model (BSM). While Paper I mainly serves as a ``tool paper'' in which the results can be used to simplify certain calculations of one-loop effects from new heavy particles, Paper II--IV all deal with consequences of family symmetries in several BSM scenarios. Paper I. We derive expressions for any

How a terror attack affects right-wing authoritarianism, social dominance orientation, and their relationship to torture attitudes

Self‐reported level of right‐wing authoritarianism (RWA), the two facets of social dominance orientation (SDO‐Dominance and SDO‐Egalitarianism) and pro‐torture attitudes were measured both in the immediate aftermath (terror salience, N = 152) of the terror attacks in Paris and Brussels and when terrorism was not salient (non‐salience, N = 140). Results showed that RWA and pro‐torture attitudes, bu

Development of a tool for rapidly assessing the implementation difficulty and emissions benefits of innovations

Consumer goods manufacturers aiming to reduce the environmental impact associated with their products commonly pursue incremental change strategies, but more radical approaches may be required if we are to address the challenges of sustainable consumption. One strategy to realize step change reductions is to prepare a portfolio of innovations providing different levels of impact reduction in excha

A value mapping tool for sustainable business modelling

Purpose: Although business models that deliver sustainability are increasingly popular in the literature, few tools that assist in sustainable business modelling have been identified. This paper investigates how businesses might create balanced social, environmental and economic value through integrating sustainability more fully into the core of their business. A value mapping tool is developed t

Understanding environmental performance variation in manufacturing companies

Purpose: Sustainability is an area of increasing interest for industry and its stakeholders, and some companies now aspire to address sustainability issues (e.g. carbon emissions) at strategic and operational levels. As companies are exploring the issues, they attempt to embed sustainability in their planning and management systems. It is at this point that the domains of environmental concern and

Embedding sustainability in business modelling through multi-stakeholder value innovation

This paper investigates how businesses might create balanced social, environmental and economic value through integrating sustainability more fully into the core of their business. For this purpose a more systematic approach to business model innovation for sustainability is required. A novel value mapping tool is proposed to help firms create value propositions better suited for sustainability. T

From refining sugar to growing tomatoes : Industrial ecology and business model evolution

This article seeks to advance the understanding of the relationship between industrial ecology (IE) and business model innovation for sustainability as a means and driver of new value creation and competitive advantage by expanding the understanding of industrial symbiosis (IS) and internal symbiosis. This is explored through the case study of British Sugar, which, at the time of writing, is the U

Evaluation of Different Turbocharger Configurations for a Heavy-Duty Partially Premixed Combustion Engine

The engine concept partially premixed combustion (PPC) has proved higher gross indicated efficiency compared to conventional diesel combustion engines. The relatively simple implementation of the concept is an advantage, however, high gas exchange losses has made its use challenging in multi-cylinder heavy duty engines. With high rates of exhaust gas recirculation (EGR) to dilute the charge and he

Smart cities as organizational fields : A framework for mapping sustainability-enabling configurations

Despite the impressive growth of smart city initiatives worldwide, an organizational theory of smart city has yet to be developed, and we lack models addressing the unprecedented organizational and management challenges that emerge in smart city contexts. Traditional models are often of little use, because smart cities pursue different goals than traditional organizations, are based on networked,

Incommensurability and vagueness in spectrum arguments : options for saving transitivity of betterness

The spectrum argument purports to show that the better-than relation is not transitive, and consequently that orthodox value theory is built on dubious foundations. The argument works by constructing a sequence of increasingly less painful but more drawn-out experiences, such that each experience in the spectrum is worse than the previous one, yet the final experience is better than the experience

GAD65-specific autoantibodies enhance the presentation of an immunodominant T-cell epitope from GAD65

GAD65 autoantibodies (GAD65Ab) are highly prevalent in type 1 diabetes, but their functional role in the pathogenesis of the disease and their relationship to T-cell reactivity to GAD65 is still unclear. We tested the hypothesis that GAD65Ab modulate presentation of GAD65 to T-cells. T-cell hybridoma T33.1, which recognizes the GAD65 274-286 epitope in the context of HLA-DRB1*0401, was incubated w

Prognostic factors for the course of β cell function in autoimmune diabetes

This study presents a 2-yr follow-up of 281 patients, aged 15-34 yr, diagnosed with diabetes between 1992 and 1993. At diagnosis, 224 (80%) patients were positive for at least one of the following autoantibodies: islet cell antibodies (ICAs), glutamic acid decarboxylase antibodies (GADAs), or tyrosine phosphatase antibodies (IA-2As); the remaining 57 (20%) patients were negative for all three auto

Newly diagnosed latent autoimmune diabetes in adults (LADA) is associated with low level glutamate decarboxylase (GAD65) and IA-2 autoantibodies

A quantitative assay with microSepharose was used to determine GAD65Ab and IA-2Ab levels in 771 population-based patients diagnosed with diabetes mellitus at 15 to 34 years of age, and in 828 matched controls. Among the patients, 587 (76%) were classified with type I, 108 (14%) with type II, and 76 (10%) with unclassifiable diabetes. The levels above normal demonstrated a prevalence of GAD65Ab in
