We perform a minimum distance analysis of a class of two-dimensional intersymbol interference (ISI) channels applicable to multitrack magnetic recording and orthogonal frequency division multiplex transmission systems. Exact minimum distance for a wide class of ISI responses is derived. The fundamental analytical technique is to transform the channel into an equivalent minimum phase channel. The r
Objective. Due to the high incidence of neonatal complications in diabetic pregnancies, the aim of our study was to investigate whether elective cesarean section could prevent adverse neonatal outcome. Design. Population-based study. Setting. Data were extracted from the Swedish Medical Birth Registry. Population. All women (n=13 491) with diabetic pregnancies during the period 1990-2007. Methods.
Väl fungerande bytespunkter är viktiga för kollektivtrafikens konkurrenskraft. Själva bytet, som är en del av varje resa, kan upplevas som en stor del av reskedjan, varför det är viktigt att bytestiden minimeras men även att bytespunkten erbjuder så hög komfort- och servicenivå som möjligt. Grunden för projektet är konstaterandet att våra kunskaper är bristfälliga när det gäller hur viktig bytespu
Denna artikel analyserar den Europeiska upphovsrättens stigberoende (path dependence) i termer av en rättslig inlåsning oförmögen att anpassa sig till nyare sociala praktiker i ett digitalt samhälle. Artikeln härleder inlåsningen till framförallt tre huvudskäl relaterade till a) transaktionskostnader, b) makt, och c) nyckelmetaforers relation till tankestrukturer. Genom att analysera den moderna e
Aims: To examine biomarkers of oxidative stress (oxs), and endothelin (ET)-1, in hypertensive patients with atherosclerotic renal artery stenosis (ARAS) and to evaluate the effect of percutaneous transluminal renal angioplasty (PTRA). Methods: Baseline measurements were made immediately before renal angiography in patients with suspected ARAS (significant ARAS, n = 83, and non-RAS, n = 59) and in
Feedbacks mechanisms are essential components of our climate system, as they either increase or decrease changes in climate-related quantities in the presence of external forcings. In this work, we provide the first quantitative estimate regarding the terrestrial climate feedback loop connecting the increasing atmospheric carbon dioxide concentration, changes in gross primary production (GPP) asso
Orchestral playing is a central practice within Western European classical music. Previous research in the field of orchestral musicians’ learning and knowledge has mainly focused on students’ learning orchestral playing. Working conditions and work-related problems were also emphasized in previous studies. This thesis, however, focuses on professional orchestral musicians’ knowledge and learning.
My research has been focused on eye and limb development with regard to the transcription factor PITX2. In the first paper we present an Axenfeld-Rieger syndrome PITX2 gain-of-function eye mouse model. Axenfeld-Rieger syndrome is a rare autosomal disorder affecting the development of eyes, teeth and abdomen. The eye defects consist of anomalies in the anterior segment. In addition, almost 50% of A
The introduction of total prostate specific antigen (total PSA) testing in blood has revolutionized the detection and management of men with prostate cancer (PCa). The objective of this review was to discuss the challenges of PCa biomarker research, definition of the type of PCa biomarkers, the statistical considerations for biomarker discovery and validation, and to review the literature regardin
A predicting model for soft dielectric elastomer generators (DEGs) must consider a realistic model of the electromechanical behaviour of the elastomer filling, the variable capacitor and of the electrical circuit connecting all elements of the device. In this paper such an objective is achieved by proposing a framework for reliable simulations of soft energy harvesters. In particular, a simple ele
We present measurements of e+e- production at midrapidity in Au+Au collisions at sNN=200 GeV. The invariant yield is studied within the PHENIX detector acceptance over a wide range of mass (mee<5 GeV/c2) and pair transverse momentum (pT<5 GeV/c) for minimum bias and for five centrality classes. The e+e- yield is compared to the expectations from known sources. In the low-mass region (mee=0.30-0.76
Background: Refugees have often been exposed to torture in their countries of origin. Rehabilitation of tortured refugees living in Denmark is offered by the specialized Rehabilitation and Research Centre for Torture Victims in Copenhagen. After an interdisciplinary assessment eligible patients are recommended rehabilitation. Objective: To explore tortured refugees' expectations of the multidiscip
In web-based health promotion programs, large variations in participant engagement are common. The aim was to investigate determinants of high use of a worksite self-help web-based program for stress management. Two versions of the program were offered to randomly selected departments in IT and media companies. A static version of the program including health screening tool, diary and information
In this thesis model reduction methods for linear time invariant systems are investigated. The reduced models are computed using semidefinite programming. Two ways of imposing the stability constraint are considered. However, both approaches add a positivity constraint to the program. The input to the algorithms is a number of frequency response samples of the original model. This makes the comput
The Lund dipole model DIPSY is based on BFKL evolution and saturation. It can be applied to collisions between electrons, protons, and nuclei. In this paper, I present some recent results for exclusive final states in inelastic collisions, a method to generate final states in diffractive excitation, and some results for collisions with nuclei.
Signaling of platelet derived growth factor receptor alpha (PDGFRA) is critically involved in the development of gliomas. However, the clinical relevance of PDGFRA expression in glioma subtypes and the mechanisms of PDGFRA expression in gliomas have been controversial. Under the supervision of morphological diagnosis, analysis of the GSE16011 and the Repository of Molecular Brain Neoplasia Data (R
Landfill leachates usually need to be treated before discharged. and using soil-plant systems for this has gained substantial interest in Sweden and in the UK A three-year field study was conducted in central Sweden to quantify plant response, treatment efficiency and impact on groundwater quality of landfill leachate irrigation of short-rotation willow coppice (Salix) Two willow varieties were te
