Process-based models not always better than empirical models for predicting budburst of Norway spruce and birch in Europe.

Budburst models have mainly been developed to capture the processes of individual trees, and vary in their complexity and plant physiological realism. We evaluated how well eleven models capture the variation in budburst of birch and Norway spruce in Germany, Austria, the United Kingdom and Finland. The comparison was based on the models performance in relation to their underlying physiological as

Multi-professional and multi-dimensional group education - a key to action in elderly persons

Purpose: This study was intended to evaluate a multi-professional health-promoting and disease-preventive intervention organized as multi-professional senior group meetings, which addressed home-dwelling, independently living, cognitively intact elderly persons (80 +/-), by exploring the participants' experiences of the intervention. Method: The focus group methodology was used to interview a tota

Social Network Characteristics and Daily Smoking among Young Adults in Sweden

A large number of studies have shown that friends’ smoking behavior is strongly associated with an individual’s own risk for smoking. However, few studies have examined whether other features of social networks, independently or conjointly with friends’ smoking behavior, may influence the risk for smoking. Because it is characterized by the growing importance of friendship networks, the transition

A search for t(t)over-bar resonances in lepton plus jets events with highly boosted top quarks collected in pp collisions at root s=7 TeV with the ATLAS detector

A search for resonant production of high-mass top-quark pairs is performed on 2.05 fb(-1) of proton-proton collisions at root s = 7 TeV collected in 2011 with the ATLAS experiment at the Large Hadron Collider. This analysis of the lepton+jets final state is specifically designed for the particular topology that arises from the decay of highly boosted top quarks. The observed t (t) over bar invaria

Re-Os and U-Pb constraints on gold mineralisation events in the Meso- to Neoarchaean Storo greenstone belt, Storo, southern West Greenland

The Storo greenstone belt in Godthabsfjord, southern West Greenland consists of juxtaposed rock units of different age and origin, and hosts gold mineralisation that is associated with arsenopyrite along a contact between lithological units and along the axial plane of a large fold core. The age and origin of the gold is debatable, but in this paper, we present new arsenopyrite Re-Os and zircon U-

Molecular Dynamics Simulations of Intrinsically Disordered Proteins: Force Field Evaluation and Comparison with Experiment

An increasing number of studies using molecular dynamics (MD) simulations of unfolded and intrinsically disordered proteins (IDPs) suggest that current force fields sample conformations that are overly collapsed. Here, we study the applicability of several state-of-the-art MD force fields, of the AMBER and GROMOS variety, for the simulation of Histatin 5, a short (24 residues) cationic salivary ID

Efficient broadcasting in radio networks with long-range interference

We study broadcasting, also known as one-to-all communication, in synchronous radio networks with known topology modeled by undirected (symmetric) graphs, where the interference range of a node is likely exceeding its transmission range. In this model, if two nodes are connected by a transmission edge they can communicate directly. On the other hand, if two nodes are connected by an interference e

Environmental clustering of drug abuse in households and communities: multi-level modeling of a national Swedish sample

Both epidemiological and genetically informative studies indicate that shared environmental influences contribute to resemblance in siblings for drug abuse (DA). To what degree do these influences arise from living in the same household versus residing in the same community? We performed a cross-classified multi-level logistic regression on all individuals born in Sweden 1975-1990 (N = 1558,654).

Economic considerations related to choice of intraocular lens (IOL) and posterior capsule opacification frequency - a comparison of three different IOLs.

Purpose: To evaluate the posterior capsule opacification (PCO) rates in three different modern standard intraocular lenses (IOL) and analyse the related cost. Methods: Retrospective study of medical records from 1527 patients who underwent uneventful cataract surgery by phacoemulsification with posterior chamber implantation of either AcrySof SN60 (n = 375), Akreos Adapt (n = 350) or Tecnis Acryl

Search for squarks and gluinos with the ATLAS detector in final states with jets and missing transverse momentum using 4:7 fb(-1) of root s=7 TeV proton-proton collision data

A search for squarks and gluinos in final states containing jets, missing transverse momentum and no high-p(T) electrons or muons is presented. The data represent the complete sample recorded in 2011 by the ATLAS experiment in 7 TeV proton-proton collisions at the Large Hadron Collider, with a total integrated luminosity of 4.7 fb(-1). No excess above the Standard Model background expectation is o

Determination of the biodistribution and dosimetry of (123)I-FP-CIT in male patients with suspected Parkinsonism or Lewy body dementia using planar and combined planar and SPECT/CT imaging.

In this study, (123)I-FP-CIT biodistribution and dosimetry was determined in 10 adult male patients using planar gamma camera imaging alone or in combination with single photon emission computed tomography /X-ray computed tomography (SPECT/CT) imaging. Dosimetric assessment using planar plus SPECT/CT imaging resulted in significantly different estimates of organ-absorbed doses compared to estimate

Tests of HPGe- and scintillation-based backpack γ-radiation survey systems.

The performance of three different backpack-mounted γ-radiation survey systems has been investigated. The systems are based on a LaBr3:Ce detector and a NaI(Tl) detector both with active volume dimensions of 76.2 mm in diameter and 76.2 mm length and a 123% relative efficiency HPGe detector. The detection limits of the systems were tested in a controlled outdoor environment in Sweden, followed by

Phase Coexistence in a Dynamic Phase Diagram.

Metastability and phase coexistence are important concepts in colloidal science. Typically, the phase diagram of colloidal systems is considered at the equilibrium without the presence of an external field. However, several studies have reported phase transition under mechanical deformation. The reason behind phase coexistence under shear flow is not fully understood. Here, multilamellar vesicle (

TOA-Based Self-Calibration of Dual-Microphone Array

In this paper, we study the time-of-arrival (TOA) based self-calibration problem of dual-microphone array for known and unknown rack distance, and also for different combinations of dimension for the affine spaces spanned by the receivers and by the senders. Particularly, we analyze the minimum cases and present minimum solvers for the case of microphones and speakers in 3-D/3-D, in 2-D/3-D, and i

Using item response theory improved responsiveness of patient-reported outcomes measures in carpal tunnel syndrome

Objective: To compare responsiveness based on item response theory (IRT) with that based on conventional scoring for two patient-reported outcomes measures in carpal tunnel syndrome (CTS); the short disabilities of the arm, shoulder, and hand (QuickDASH) measure, and the 6-item CTS symptoms scale (CTS-6). Study Design and Setting: Prospective cohort study of patients with CTS undergoing carpal tun

The influence of climate on C-13/C-12 and O-18/O-16 ratios in tree ring cellulose of Pinus sylvestris L. growing in the central Scandinavian Mountains

The stable isotope composition of tree rings is known to contain valuable information of past climatic and environmental changes, which may be used as a complement to tree ring width and maximum latewood density in climate reconstructions. In this study we examine the character and strength of the climate signal captured in the delta O-18 and delta C-13 values of Scots pine (Pinus sylvestris L.) t

Peace mediation and the minefield of international recognition games

This article analyzes the intricate dynamics between international mediation and the quest for recognition in protracted conflict. The overarching aim is two-fold: to analyze how the struggle for recognition relates to protracted conflict, and why, when and in what ways recognition poses a barrier to efficient peace diplomacy and mediation. The article explores how preferences and interests are in
