Sequential Monte Carlo smoothing with application to parameter estimation in nonlinear state space models
This paper concerns the use of sequential Monte Carlo methods (SMC) for smoothing in general state space models. A well-known problem when applying the standard SMC technique in the smoothing mode is that the resampling mechanism introduces degeneracy of the approximation in the path space. However, when performing maximum likelihood estimation via the EM algorithm, all functionals involved are of

Cationic uremic toxins affect human renal proximal tubule cell functioning through interaction with the organic cation transporter
Several organic cations, such as guanidino compounds and polyamines, have been found to accumulate in plasma of patients with kidney failure due to inadequate renal clearance. Here, we studied the interaction of cationic uremic toxins with renal organic cation transport in a conditionally immortalized human proximal tubule epithelial cell line (ciPTEC). Transporter activity was measured and valida
Music and Musicology in the Light of Intermediality and Intermedial Studies
In this article I show how aesthetic disciplines, to which musicology belongs, have suffered from a crisis of creativity for the past decade or so. By crisis of creativity I mean the development of new theories, which can contribute to new knowledge about music, from both historical and contemporary prespectives. With help from theories that normally lies outside of the institutional discourse of

Measurement of gamma(1S+2S+3S) production in p plus p and Au plus Au collisions at root sNN=200 GeV
Measurements of bottomonium production in heavy-ion and p + p collisions at the Relativistic Heavy Ion Collider (RHIC) are presented. The inclusive yield of the three states, (1S + 2S + 3S), was measured in the PHENIX experiment via electron-positron decay pairs at midrapidity for Au + Au and p + p collisions at root sNN = 200 GeV. The (1S + 2S + 3S) -> e(+)e(-) differential cross section at midra
Complex timing of Marsh Harrier Circus aeruginosus migration due to pre- and post-migratory movements
We tracked three juvenile and 14 adult Marsh Harriers Circus aeruginosus from southern Sweden via satellite to investigate migration strategies. Four individuals were tracked for at least two years. All three juveniles and four of the adults made west-oriented pre-migratory movements well before the onset of autumn migration, and trans-Saharan migrants visited post-migratory stopover areas in trop

Sample sizes for estimating key ecosystem characteristics in a tropical terra firme rainforest
This study evaluated the sample sizes necessary to estimate several soil and vegetation characteristics within 10% confidence intervals with 95% probability in three terra firme tropical rainforest sites. Across all three plots, the most spatially heterogeneous variables were measurements of total standing crop root mass, ground surface litter mass, litter fall, root growth and soil respiration wh
Social determinants and the role of maternal health care services for equity in maternal health in Ghana from 1988 – 2008
Popular Abstract in Swedish Avhandlingen utgår från förhållandet att mödradödligheten traditionellt varit en tungt vägande faktor för kvinnors totala sjukdomsbörda i låginkomstländer. Mödradödligheten är starkt knuten till såväl allmänna levnadsförhållanden i samhället som till tillgång och kvalitet av professionell hälsovård. Det är därför inte förvånande att mer än 99 av 100 mödradödsfall i värlMaternal health services are the least equitable health care services in most low- and middle-income countries. Improving maternal health in Ghana continues to be a major public health challenge. Socio-economic inequalities within the country are greatly reducing the use of maternal health care services despite government policy reforms to improve access to maternal health care services and interv
Screening of women for intimate partner violence: a pilot intervention at an outpatient department in Tanzania
Intimate partner violence (IPV) is a public health problem in Tanzania with limited health care interventions. Objectives: To study the feasibility of using an abuse screening tool for women attending an outpatient department, and describe how health care workers perceived its benefits and challenges. Methods: Prior to screening, 39 health care workers attended training on gender-based violence an

Geometric integration of Hamiltonian systems perturbed by Rayleigh damping
Explicit and semi-explicit geometric integration schemes for dissipative perturbations of Hamiltonian systems are analyzed. The dissipation is characterized by a small parameter epsilon, and the schemes under study preserve the symplectic structure in the case epsilon=0. In the case 0
Screening for osteoporosis reduced new fracture incidence by almost half A 6-year follow-up of 592 fracture patients from an osteoporosis screening program
Background and purpose Fractures can be prevented if osteoporosis is identified and treated. In 2002, we initiated a screening program at our orthopedics department, in which patients between 50 and 75 years of age with a wrist, shoulder, vertebral, or hip fracture are assessed by DEXA of the hip and spine and encouraged to see their doctor for decision on treatment regarding osteoporosis. The pat
First results from the Lund NMP particle detector system
The design and first results from a Double Sided Silicon Strip Detector (DSSSD) recently installed at the Lund Nuclear Microprobe facility (NMP) are presented. The detector has 64 sector strips and 32 ring strips, which in combination give more than 2000 detector cells, each with characteristics comparable with a standard surface barrier detector (SBD). The detector has been tested both with radio
Comparative analysis of the effects of neurotrophic factors CDNF and GDNF in a nonhuman primate model of Parkinson’s disease
Cerebral dopamine neurotrophic factor (CDNF) belongs to a newly discovered family of evolutionarily conserved neurotrophic factors.We demonstrate for the first time a therapeutic effect of CDNF in a unilateral 6-hydroxydopamine (6-OHDA) lesion model of Parkinson’s disease in marmoset monkeys. Furthermore, we tested the impact of high chronic doses of human recombinant CDNF on unlesionedmonkeys and
Att se empatiskt - Samtida fotografiers möte med globaliserade rörelser, samspel och konflikter
This article takes a selection of works of contemporary photography as starting points in a discussion about globalised movements, connections, and conflicts. The aim of the article is two-fold; first, to bring out and analyze how contemporary photography today finds new strategies with which to engage with aspects of the phenomenon of globalisation, and second, to contribute to a beginning tenden
A beta Immunotherapy Protects Morphology and Survival of Adult-Born Neurons in Doubly Transgenic APP/PS1 Mice
The hippocampus is heavily affected by progressive neurodegeneration and beta-amyloid pathology in Alzheimer's disease (AD). The hippocampus is also one of the few brain regions that generate new neurons throughout adulthood. Because hippocampal neurogenesis is regulated by both endogenous and environmental factors, we determined whether it benefits from therapeutic reduction of beta-amyloid pepti
The Impact of Domestication on the Chicken Optical Apparatus
Domestication processes tend to release animals from natural selection and favour traits desired by humans, such as food-production and co-operative behaviour. A side effect of such selective breeding is the alteration of unintended traits. In this paper, we investigate how active selection for egg production in chickens has affected the visual system, in particular the optical sensitivity that re
