BACKGROUND We hypothesized that certain patient characteristics have different effects on the risk of early stem loosening in total hip arthroplasty (THA). We therefore conducted a case-control study using register-database records with the aim of identifying patient-specific risk factors associated with radiographic signs of aseptic loosening of the(More)
Global warming leads to increased intensity and frequency of weather extremes. Such increased environmental variability might in turn result in increased variation in the demographic rates of interacting species with potentially important consequences for the dynamics of food webs. Using a theoretical approach, we here explore the response of food webs to a(More)
The outcomes of 106 total knee arthroplasties implanted using a soft tissue balancing surgical technique at one surgical centre were used to assess the accuracy maintaining the knee’s original joint line (JL). The aim of the study was to determine whether there is a shift of the presumed joint line after surgery. Preoperative and post-operative radiographs(More)
We postulated that certain patient characteristics have different effects on early THA component loosening. With two matched case-control studies we assessed 3,028 cups and 5,224 stems. Loosening was defined using signs of mechanical component failure on routine follow-up radiographs or revision for aseptic loosening. Women and men had similar cup-loosening(More)
Climate change is increasingly affecting the structure and dynamics of ecological communities both at local and at regional scales, and this can be expected to have important consequences for their robustness and long-term persistence. The aim of the present work is to analyse how the spatial structure of the landscape and dispersal patterns of species(More)
Technological and economic trends determining the development of High Performance Computing (HPC) hardware architectures and systems in the time range 2006–2011 is investigated, as well as its implications for scientific applications in the area of molecular modeling. In part I of the report, information regarding the HPC development has been obtained by(More)
The initial formation stages (i.e., island nucleation, island growth, and island coa-lescence) set characteristic length scales during growth of thin films from the vapor phase. They are, thus, decisive for morphological and microstructural features of films and nanostructures. Each of the initial formation stages has previously been well-investigated(More)
Investigations of activation energy barriers for Al surface hopping on α-Al2O3 (0001) surfaces have been carried out by means of first-principles density functional theory calculations and the nudged elastic band method. Results show that surface diffusion on the (most stable) Al-terminated surface is relatively fast with an energy barrier of 0.75 eV,(More)
