Biophysical models that describe the outcome of white matter diffusion MRI experiments have various degrees of complexity. While the simplest models assume equal-sized and parallel axons, more elaborate ones may include distributions of axon diameters and axonal orientation dispersions. These microstructural features can be inferred from diffusion-weighted signal attenuation curves by solving an i

Purpose Hip dislocation after arthroplasty for femoral neck fractures (FNF) remains a serious complication. The aim of our study was to investigate FNF patients treated with THA, with a special focus of comparing the effect of surgical approach and femoral head size on the risk of revision for dislocation. Methods Data were derived from the Lithuanian Arthroplasty Register, and we calculated the c

The discipline of epidemiology, which holds major influence on public health policy as well as on clinical medical practice, has in recent decades to a large extent been concerned with the identification of factors and markers of risk for disease. Much health information and intervention is thus informed by a wealth of studies on a variety of risk factors, of which the individual is encouraged to

Many developing countries would like to increase employment in the formal sectors. One way to accomplish this goal may be to encourage the entrance of foreign firms. We examine employment growth in Indonesian plants taken over by foreign owners from domestic ones. We also examine the effect of FDI during different trade regimes and the timing of employment effects following an acquisition. For pla

Application of C-rich plant residues can change the soil system from C-limitation for microbial growth to limitation by other nutrients. However, the initial nutrient status of the soil may interact with the added amount of residues in determining limitation. We studied this interactive effect in soils from the Harvard Forest LTER, where annual addition of N since 1988 has resulted in soils with d

Background: Screening for bacterial colonization and antimicrobial resistance (AMR) among a defined population could aid in the identification of at-risk populations and provide targets for antibiotic stewardship and infection control programmes. Methods: Two hundred and sixty-eight participants at 11 Swedish nursing homes underwent serial screening for colonization with Escherichia coli between M

Internal erosion is one of the major reasons for embankment dam failures. Despite this, the knowledge of the temporal development of internal erosion in full scale structures is limited. Detection of internal erosion is complicated using conventional methods, and new or improved methods are appreciated. Hallby was the first Swedish embankment to get a permanently installed monitoring system intend

The use of factor-augmented panel regressions has become very popular in recent years. Existing methods for such regressions require that the common factors are strong, an assumption that is likely to be mistaken in practice. Motivated by this, the current paper offers an analysis of the effect of weak, semi-weak and semi-strong factors on two of the most popular estimators for factor-augmented re

Popular Abstract in Swedish Hos barn med cerebral pares (CP) spastisk diplegi är förhöjd muskelspänning s.k. spasticitet är ett vanligt symptom som påverkar kvalitén på rörelser. Muskler blir stela och förkortas och felställningar i leder kan uppstå. Selektiv Dorsal Rhizotomi (SDR) är ett ingrepp som används för att minska spasticitet i benen och som i kombination med sjukgymnastik kan ge beståendThe overall aim of the thesis was to describe long-term development of functional outcomes in children with cerebral palsy undergoing selective dorsal rhizotomy (SDR) combined with physiotherapy and to evaluate measures used in follow-up. Five years after SDR muscle tone was reduced, passive range of motion (PROM) increased in hip, knee and foot, gross motor function measured by the Gross Motor F

Popular Abstract in Swedish Utgångspunkten för denna avhandling är passet som det utformades och användes i den Europeiska Unionen från 1999 till 2001, närmare bestämt som en förutsättning för att få passera EU:s yttre gränser och som en symbol för ett förenat Europa fritt från medlemsstaternas spektakulära nationalism. Enligt nationalismen skulle varje nation ha sin egen stat och varje stat skulThe vantage point for this thesis is the passport as it was understood and used in the European Union from 1999 to 2001, as a requirement to cross the external borders of the EU and as a symbol of a united Europe free from a spectacular nationalism of the member states. According to nationalism, every nation should have its own state, and every state should be legitimized by a nation. If the mode

This article expands current acquisition literature to include sociocultural challenges on inter-organizational levels following acquisitions of young, innovative firms. Socioculture here denotes network parties' shared values, belief systems, and practices. Three acquisitions illustrate their consequences. The young, innovative firms and their acquirers are part of different networks, have dissim

Literacy practice and discursive practice are two distinct concepts, belonging to different research traditions (new literacy studies, NLS, and critical discourse analysis, CDA). This article is an effort to enlighten the discussion of these concepts by comparing the history and scope of the concepts, the research interest and the different research methods used. Exemplifying with an analysis of 1

Context. Stars are born together from giant molecular clouds and, if we assume that the priors were chemically homogeneous and well-mixed, we expect them to share the same chemical composition. Most of the stellar aggregates are disrupted while orbiting the Galaxy and most of the dynamic information is lost, thus the only possibility of reconstructing the stellar formation history is to analyze th

Accurate assessment of energy expenditure (EE) is important for the study of energy balance and metabolic disorders. Combined heart rate (HR) and acceleration (ACC) sensing may increase precision of physical activity EE (PAEE) which is the most variable component of total EE (TEE).

In the first three years of the physics program at the relativistic heavy ion collider (RHIC) a picture was established in which the suppression of hadrons at high transverse momenta (pT) in central Au+Au collisions is explained by energy loss of quark and gluon jets in a medium of high color-charge density. Measurements of single-particle spectra for a smaller nucleus (Cu), for different center-o
