Questions: How will genetic differentiation and genetic drift in spatially structured populations be affected by different classes of autocorrelated environmental noise? How does dispersal interact with fluctuations generated from the demographic and environmental forcing in shaping the neutral genetic patterns? Model and key assumptions: Populations are regulated locally by density-dependent feed
Objective: Systemic lupus erythematosus (SLE) is a complex multi-organ disease, characterised by relapses and remissions. Designing a high-quality randomised controlled trial poses many challenges. We have developed evidenced-based recommendations for points to consider in conducting clinical trials in patients with SLE. Methods: The EULAR Task Force on SLE comprised 19 specialists and a clinical
Small for gestational age (SGA) is considered as an indicator of intrauterine growth restriction, and multiple maternal and newborn characteristics have been identified as risk factors for SGA. This knowledge is mainly based on measures of average association (ie, OR) that quantify differences in average risk between exposed and unexposed groups. Nevertheless, average associations do not assess th
The objective of the study was to compare disease characteristics over the first 5 years of disease in patients with RA, with disease onset in 1990s and 2000s, respectively.
Antenna Q optimization by a genetic algorithm with method of moments simulation at a single frequency is described. The optimized antennas may have arbitrary shapes within a rectangular region. Simulations using a commercial tool show good agreement between the predicted and realized Q factor. Furthermore, comparison with the physical bound shows that the optimized antennas perform close to the op
Background: Medial temporal lobe atrophy (MTA) is an early sign of Alzheimer's disease (AD). The current method of choice for measuring MTA is volumetric measurement based on 3D magnetic resonance imaging (MRI), but this complicated method has not been implemented clinically. Purpose: To investigate whether simple computed tomography (CT) linear measurements of the brain could be of value in AD wo
AIMS: To evaluate multi-frequency tactilometry as a method to measure vibrotactile sense in the sole of the foot in subjects with diabetes. METHODS: Vibration thresholds were investigated at five frequencies (8, 16, 32, 64 and 125 Hz) at three sites (first and fifth metatarsal heads and heel) in the sole of the foot in subjects with Type 1 and Type 2 diabetes (n = 37). Thresholds were compared wit
Popular Abstract in Swedish Hjärt-kärlsjukdom är en av västvärldens stora folksjukdomar. I Sverige drabbas årligen cirka 10 000 personer av plötsligt hjärtstopp. Den vanligaste orsaken är att en akut hjärtinfarkt orsakar ett ”elektriskt kaos” i hjärtat. Vid ett hjärtstopp upphör blodförsörjningen till hjärnan, vilket leder till medvetslöshet inom några sekunder och inom några få minuter börjar hjäThis thesis focuses on the prognostic value of electroencephalography(EEG) in comatose patients resuscitated after cardiac arrest (CA), using both simplified continuous EEG monitoring (cEEG) and routine EEG. Background: Comatose survivors are admitted to an intensive care unit (ICU) to support vital functions. Postresuscitation care includes target temperature management (TTM) for 24 hours. The d
Human stature as a measurement for evaluating physical status is used by the World Health Organiza-tion (WHO) as well as bioarchaeologists. The reason for this is that only about 80% depends on genetic factors, while 20% depend on the environment. Bad living conditions decrease stature in a population. This paper aims to make a short review of earlier reports on stature in Late Neolithic–Early Bro
Marine microbial protists, in particular, dinoflagellates, produce polyketide toxins with ecosystem-wide and human health impacts. Species of Gambierdiscus produce the polyether ladder compounds ciguatoxins and maitotoxins, which can lead to ciguatera fish poisoning, a serious human illness associated with reef fish consumption. Genes associated with the biosynthesis of polyether ladder compounds
Very little is known about the local power of second generation panel unit root tests that are robust to cross-section dependence. This article derives the local asymptotic power functions of the cross-section argumented Dickey–Fuller Cross-section Augmented Dickey-Fuller (CADF) and CIPS tests of Pesaran (2007), which are among the most popular tests around.
Most fundamentals modes of the water dimer have been experimentally determined, and the frequencies have been measured in either neon or parahydrogen matrices. The band strengths of all intramolecular and most intermolecular fundamentals of the water dimer have been measured. The results are further corroborated by comparison with the corresponding data for the fully deuterated water dimer. DFT ca
Popular Abstract in Swedish Antalet äldre i befolkningen ökar i förhållande till andra åldersgrupper. Detta beskrivs medföra en ekonomisk utmaning för samhället och att fler äldre behöver skjuta upp sin ålderspension. Avhandlingen bygger på fyra studier med det övergripande syftet att bidra till ökad kunskap om faktorer som medverkar till ett förlängt alternativt förkortat arbetsliv bland personerIn most of the industrialised world, the proportion of older and retired people in the population is continuously increasing. This will have budgetary implications for maintaining the welfare state, because the active working section of the population must fund the non-active and old population. Aim: The overall aim of this thesis was to obtain knowledge about older workers’ work and life situatio
