Quantum annealing is a promising approach for obtaining good approximate solutions to difficult optimization problems. Folding a protein sequence into its minimum-energy structure represents such a problem. For testing new algorithms and technologies for this task, the minimal lattice-based [hydrophobic (H) or polar (P) beads] HP model is well suited, as it represents a considerable challenge desp
Various mechanisms of secondary ice production (SIP) cause multiplication of numbers of ice particle, after the onset of primary ice. A measure of SIP is the ice enhancement ratio (“IE ratio”) defined here as the ratio between number concentrations of total ice (excluding homogeneously nucleated ice) and active ice-nucleating particles (INPs). A convective line observed on 11 May 2011 over the Sou
OBJECTIVE: To explore and quantify the relative strengths of the genetic contribution vs the contribution of modifiable environmental factors to severe osteoarthritis (OA) having progressed to total joint arthroplasty.DESIGN: Incident data from the Norwegian Arthroplasty Registry were linked with the Norwegian Twin Registry on the National ID-number in 2014 in a population-based prospective cohort
OBJECTIVE: To explore factors related to hand pain in persons with radiographic hand osteoarthritis (OA).METHODS: Persons in the Musculoskeletal Pain in Ullensaker Study with radiographic hand OA (≥1 joint with Kellgren/Lawrence grade ≥2) were included (n = 530). We examined the cross-sectional association between possible explanatory variables and hand pain in the entire sample and in 2 hand OA p
This is the story of how a large research facility of broad European and global interest, the European Spallation Source (ESS), ended up in the small university town of Lund in Sweden. This happened in spite of the fact that a number of influential European countries were at one time or another competitors to host the facility. It is also a story about politics which attempts to illustrate how clo
Context: Offspring of women with gestational diabetes (O-GDM) or type 1 diabetes mellitus (O-T1DM) have been exposed to hyperglycemia in utero and have an increased risk of developing metabolic disease in adulthood. Design: In total, we recruited 206 adult offspring comprising the two fetal hyperglycemic groups, O-GDM and O-T1DM, and, as a control group, offspring from the background population (O
Lung Clearance Index (LCI) provides an overall measurement of ventilation inhomogeneity. This population-based study examines whether LCI predicts pulmonary obstruction and incidence of chronic obstructive pulmonary disease (COPD) events over a long-term follow-up. Multiple breath nitrogen washout and spirometry were performed in 674 men from the cohort “Men born in 1914” at age 55 years. Subjects
Aim: To explore pain screening in CPUP, a follow-up surveillance programme for people with cerebral palsy (CP), specifically to describe reported pain prevalence, localizations, patterns of distribution; to compare with studies using psychometrically sound assessment instruments; and to assess agreement between pain documented in CPUP and medical records. Method: Registry study of a population wit
Objective: The aim of this study was to evaluate clinically relevant complications within 14 days after extracorporeal shockwave lithotripsy (ESWL) in a modern setting. Materials and methods: Consecutive ESWL treatments between 2009 and 2015 in Ängelholm Hospital, Sweden, were analyzed retrospectively. The primary outcome was complications in patients seeking medical attention within 14 days after
Background: Switch from first line antiretroviral therapy (ART) to second-line ART is common in clinical practice. However, there is limited knowledge of to which extent different reason for therapy switch are associated with differences in long-term consequences and sustainability of the second line ART. Material and methods: Data from 869 patients with 14601 clinical visits between 1999–2014 wer
Objective. Our aim was to test the hypothesis that a combination of markers for Type 1 diabetes (glutamate decarboxylase and IA-2 autoantibodies) and for Type 2 diabetes [oral glucose tolerance test (OGTT) and body mass index (BMI)], would predict clinical diabetes in a regional population. Design. A population-based follow-up cohort study. Setting. Participants visited the primary health care cen
Membrane hybrid processes-coagulation coupled with ultrafiltration (UF)-have become a common method to comply with the legal, chemical, and microbiological requirements for drinking water. The main advantages of integrating coagulation with membrane filtration are the enhanced removal of natural organic matter (NOM) and reduced membrane fouling. With in-line coagulation, coagulants are patched int
Effects of the bluff-body's position on diffusion flame structures and flame instability characteristics were investigated experimentally. A flame regime diagram together with the corresponding flow fields were proposed to evaluate the influences caused by the alternation of bluff-body's position. The disk shape bluff-body was placed 10 mm downstream or at the same height with the annular channel
Introduction: To investigate the incidence of neonatal early-onset group B streptococcal (GBS) infection in Sweden after promulgation of guidelines (2008) for risk factor-based intrapartum antibiotic prophylaxis, and evaluate the presence of risk factors and obstetric management in mothers. Material and methods: National registers were searched for infants with early-onset GBS infection during 200
In circumpolar regions, coastlines offer rich constellations of diverse resources, and have long been a focus of human habitation. Despite the rich archaeological records that are located along many northern coastlines, there is a relatively limited understanding of the range of factors that informed local settlement strategies. Northern Norway has one of the world’s longest and best-preserved arc
The effect of human recombinant cystatin C, a cysteine proteinase inhibitor, on bone resorption in vitro was evaluated. Bone resorption was assessed by analyzing the release of 45Ca and 3H from mouse calvarial bones prelabeled in vivo by injections with 45Ca or [3H]proline, respectively. In 24 h cultures, cystatin C (50 micrograms/ml) significantly inhibited the release of 45Ca and 3H stimulated b
OBJECTIVES: There is a need for updated haematological reference data in infancy. This study aimed to define intervals for haemoglobin and red blood cell biomarkers based on data from a large cohort of longitudinally followed Swedish infants. DESIGN: Longitudinal cohort study. SETTING: Two Swedish study centres. PARTICIPANTS: Three community-based populations including 442 presumably healthy infan
Objective: Both auditory and visual hypersensitivity are clinical features of mental fatigue after acquired brain damage or in neurological disorders. Both types of hypersensitivity are also associated with attention deficits, especially in neurodevelopmental syndromes. The aim of this study was to examine auditory and visual hypersensitivity, and associations to attention, in a group of children
Context. 55 Cnc e is a transiting super-Earth (radius 1.88 R⊕ and mass 8 M⊕) orbiting a G8V host star on a 17-h orbit. Spitzer observations of the planet's phase curve at 4.5 μm revealed a time-varying occultation depth, and MOST optical observations are consistent with a time-varying phase curve amplitude and phase offset of maximum light. Both broadband and high-resolution spectroscopic analyses
