Context. New instrumental capabilities and the wealth of astrophysical information extractable from the near-infrared wavelength region have led to a growing interest in the field of high resolution spectroscopy at 1-5 mu m. Aims. We aim to provide a library of observed high-resolution and high signal-to-noise-ratio near-infrared spectra of stars of various types throughout the Hertzsprung-Russell

Power and energy consumption, today essential in all types of systems, can be reduced by scaling the voltage/frequency at runtime and/or powering down idle components. Efficient management requires not only pertinent decisions, but also early access to workload information, as well as domain specific solutions. This paper focuses on runtime energy management for streaming applications running on m

Experiments performed with the high-contrast 0.7-J 35-fs Ti:sapphire laser at the Lund Laser Centre focused into a helium gas jet have produced quasi-monoenergetic electron beams with energies up to 150 MeV. The beam is produced as a result of controlled wavebreaking of a wakefield generated by the relativistically channeled laser beam. Under the best conditions of laser energy and plasma density,

Background: Array comparative genomic hybridization (aCGH) is commonly used to screen different types of genetic variation in humans and model species. Here, we performed aCGH using an oligonucleotide gene-expression array for a non-model species, the intertidal snail Littorina saxatilis. First, we tested what types of genetic variation can be detected by this method using direct re-sequencing and

Objectives To describe clinical history and ultrasound findings in patients with tubal carcinoma. Methods Patients with a histological diagnosis of tubal cancer who had undergone preoperative ultrasound examination were identified from the databases of 13 ultrasound centers. The tumors were described by the principal investigator at each contributing center on the basis of ultrasound images, ultra

Mutations in pancreatic duodenal homeobox 1 (PDX-1) can cause a monogenic form of diabetes (maturity onset diabetes of the young 4) in humans, and silencing Pdx-1 in pancreatic β-cells of mice causes diabetes. However, it is not established whether epigenetic alterations of PDX-1 influence type 2 diabetes (T2D) in humans. Here we analyzed mRNA expression and DNA methylation of PDX-1 in human pancr

Background: In mental health care practice and research it is increasingly recognized that clients' subjective perceptions of everyday occupations, such as satisfaction, are important in recovery from mental illness. Instruments thus need to be developed to assess satisfaction with everyday occupations. The aim of the present study was to assess psychometric properties of the 13-item Satisfaction

Popular Abstract in Swedish Det enteriska nervsystemet (ENS) utgör mag-tarmkanalens eget nervsystem, ibland refererat till som “the second brain” då det uppvisar stora likheter med det centrala nervsystemet (CNS). Rubbningar i ENS ger bland annat störningar i tarmens motorik. Denna avhandling handlar om två sjukdomar i mag-tarmkanalen hos barn som bägge är uttryck för en rubbad motorik; HirschspruGastrointestinal motility disorders are common in childhood and in this thesis we look at two of them, i.e. Hirschsprung´s Disease (HD) and gastroesophageal reflux disease (GERD) in five different studies. HD is a congenital disease characterized by an abscence of ganglion cells in myenteric and submucous ganglia, most commonly in the distal part of the large bowel. In Paper I, we have studied th

The innate immune system in humans has succeeded in developing numerous mechanisms against the injurious effects of bacteria, along with their toxins as a result of several thousand years of co-evolution. The oral mucosal surface represents such a unique environment, where despite being constantly exposed to microbes and their products, overt infection and damage is a rarity. An important componen

The role of G alpha i proteins coupled to chemokine receptors in directed migration of immune cells is well understood. In this study we show that the separate class of G alpha q/11 proteins is required for the underlying ability of T cells to migrate both randomly and in a directed chemokine-dependent manner. Interfering with G alpha q or G alpha 11 using dominant negative cDNA constructs or siRN

This work deals with electro-viscoelastic modelling and simulation of dielectric elastomer actuators (DEA), including the case of deformation dependent electromechanical coupling. A large deformation modelling framework is adopted, and specific thermo- dynamically consistent material models are established. The general framework is applied to VHB49 polyacrylic polymers which are commonly used in D

We report our experience with surgery for femoral metastatic lesions, based on 216 patients who underwent a total of 245 operations for femoral metastatic lesions. The median age was 66 (30-94) years, and the most common diagnosis breast cancer, followed by prostate cancer. All patients had pain on weight bearing, 196 had pain at rest, 147 were unable to walk preoperatively, and 148 were confined

Using optimality perspectives is now regarded as an essential way of analysing and understanding adaptations and behavioural strategies in bird migration. Optimization analyses in bird migration research have diversified greatly during the two recent decades with respect to methods used as well as to topics addressed. Methods range from simple analytical and geometric models to more complex modeli

We present an overview of recent work on the spectroscopy of tungsten ions, related to tokamak edge plasma. The spectra were recorded from the newly-built low energy electron beam ion traps (EBITs) in the Shanghai EBIT laboratory. By analyzing the spectra with the help of accurate theoretical calculations, using state-of-the-art techniques, we were able to identify term and fine structure splittin

This is a description of the technique used for laparoscopy-assisted colostomy in neonates with anorectal malformations (ARM), using 2 laparoscopic ports only. The technique is easy to use and has the advantages of enabling identification of the sigmoideum, the internal genitals and to establish a stoma leaving only minimal scars in the umbilicus. In our departments, we routinely perform stoma ope
