To assess muscle strength in the knee extensors, knee flexors and ankle dorsiflexors in persons with late effects of polio, and determine how much muscle strength, gender, age and BMI are related to gait performance.
Qualitative description of spray structure and geometry in the near-field region of atomizing sprays is particularly challenging due to the lack of visibility through such optically dense media. Similarly, quantitative determination of the optical depth can be particularly underestimated as a result of detecting photons which have experienced a number of scattering events. In this paper we demonst
About 1% of giant stars have been shown to have large surface Li abundances, which is unexpected according to standard stellar evolution models. Several scenarios for lithium production have been proposed, but it is still unclear why these Li-rich giants exist. A missing piece in this puzzle is the knowledge of the exact stage of evolution of these stars. Using low-and-high-resolution spectroscopi
A mesoscale model of microstructure evolution is formulated in the present work by combining a crystal plasticity model with a graph-based vertex algorithm. This provides a versatile formulation capable of capturing finite-strain deformations, development of texture and microstructure evolution through recrystallization. The crystal plasticity model is employed in a finite element setting and allo
The aim of the study was to assess the ability to recognize ventricular fibrillation (VF) concomitant with pacing artifacts presented either alone or with clinical scenario indicating the cardiac arrest in a patient with implanted pacemaker by members of the medical emergency team.
The results of a search for supersymmetry in events with large missing transverse momentum and heavy-flavor jets using an integrated luminosity corresponding to 2.05 fb(-1) of pp collisions at root s = 7 TeV recorded with the ATLAS detector at the Large Hadron Collider are reported. No significant excess is observed with respect to the prediction for standard model processes. Results are interpret
Although the nuclear era and the Cold War superpower competition have long since passed, governments are still investing in Big Science, although these large facilities are nowadays mostly geared towards areas of use closer to utility. Investments in Big Science are also motivated not only by promises of scientific breakthroughs but also by expectations (and demands) of measurable impact, and with
We analyze a system consisting of two spherical particles immersed in a polydispersed polymer solution under theta conditions. An exact theory is developed to describe the potential of mean force between the spheres for the case where the polymer molecular weight dispersity is described by the Schulz-Flory distribution. Exact results can be derived for the protein regime, where the sphere radius (
Searches for heavy long-lived charged particles are performed using a data sample of 19.1 fb(-1) from proton-proton collisions at a centre-of-mass energy of root s = 8 TeV collected by the ATLAS detector at the Large Hadron Collider. No excess is observed above the estimated background and limits are placed on the mass of long-lived particles in various supersymmetric models. Long-lived tau slepto
Background and purpose - A shortened tibial stem could influence the early prosthetic fixation. We therefore compared the short stem to the standard-length stem using radiostereometric analysis (RSA) as primary outcome measure. Patients and methods - 60 patients were randomized to receive a cemented Triathlon total knee arthroplasty (TKA) with a tibial tray of either standard or short stem length.
In this paper, the problem of detecting target in system-dependent clutter (SDC) background with a single observation from the test cell is researched. Classical detectors, such as the generalized likelihood ratio detectors (GLRDs) and the adaptive matched filters (AMFs), etc., usually deal with the clutter and the noise as a whole. The low rank detectors (LRDs) make use of the low rank property o
In spring 1986, Lindsay Anderson appeared in a television programme on British cinema. This was part of a series of three under the heading British Cinema: Personal View, produced by Thames Television. Anderson’s contribution, Free Cinema 1956–? An Essay on Film by Lindsay Anderson, was written and directed by him. He was also the star of the programme, providing a lecture on the history of Britis
Protein conformational dynamics can be critical for ligand binding in two ways that relate to kinetics and thermodynamics respectively. First, conformational transitions between different substates can control access to the binding site (kinetics). Secondly, differences between free and ligand-bound states in their conformational fluctuations contribute to the entropy of ligand binding (thermodyna
Streptococcus pyogenes is an important human pathogen that causes a variety of diseases including life-threatening invasive diseases, such as toxic shock and deep tissue infections. Although S. pyogenes are classically considered extracellular pathogens, a clinical significance of an intracellular source has been emphasized. In patients with deep tissue infections, an intracellular reservoir of S.
This study investigated how visitors and staff in community-based activity centers in Sweden perceived the psychosocial atmosphere and whether this could be explained by the centers' orientation (work-oriented versus meeting place-oriented centers). Eighty-eight visitors and 37 staff members at three work-oriented and three meeting place-oriented centers participated. The Community-oriented Progra
Background: Only about half the studies that have collected information on the relevance of women's height and body mass index to their risk of developing ovarian cancer have published their results, and findings are inconsistent. Here, we bring together the worldwide evidence, published and unpublished, and describe these relationships. Methods and Findings: Individual data on 25,157 women with o
Genome editing via CRISPR/Cas9 has rapidly become the tool of choice by virtue of its efficacy and ease of use. However, CRISPR/Cas9-mediated genome editing in clinically relevant human somatic cells remains untested. Here, we report CRISPR/Cas9 targeting of two clinically relevant genes, B2M and CCR5, in primary human CD4(+) T cells and CD34(+) hematopoietic stem and progenitor cells (HSPCs). Use
Between 2008 and 2010, Lund University took part in three international benchmarking projects, E-xcellence+, the eLearning Benchmarking Exercise 2009, and the First Dual-Mode Distance Learning Benchmarking Club. A comparison of these models revealed a rather high level of correspondence. From this finding and from desktop studies of the current discourse regarding e-learning, a conceptual framewor
