62 former patients, who had been treated at our department for tibial shaft fracture (n 38) or knee ligament injury (n 24) 15-38 years earlier, were re-evaluated for post-traumatic osteopenia. 62 age- and sex-matched subjects without fracture served as controls. By means of a Lunar DEXA apparatus we measured the bone mineral density (BMD) in the total body, the hips and special regions of interest
Scaling attosecond sources to higher pulse energy and/or repetition rate can benefit many applications. We present a scaling framework for nonlinear light-matter interactions, applicable to attosecond pulse generation and other nonlinear phenomena as e.g. filamentation.
This paper focuses on the event-based distributed robust leaderless synchronization control for multiple Euler-Lagrange systems with directed communication topology that contains a directed spanning tree. Update frequency of the system is reduced by taking advantages of the event-triggered approach, which can help extend the service life of the controller. Robust control theory is employed to guar
Electrocardiographic (ECG) criteria for the diagnosis of inferior myocardial infarction (IMI) have high specificity but low sensitivity. Vectorcardiographic IMI criteria attain higher sensitivity without sacrificing specificity. One approach to improving ECG interpretation is to synthesize VCG loops from the 12-lead ECG. The performance of synthesized VCG (SVCG) was assessed, using the Frank VCG c
Various applications of the mean field theory (MFT) technique for obtaining solutions close to optimal minima in feedback networks are reviewed. Using this method in the context of the Boltzmann machine gives rise to a fast deterministic learning algorithm with a performance comparable with that of the backpropagation algorithm (BP) in feature recognition applications. Since MFT learning is bidire
This special issue brings together scholars of media, sociology, and political science to examine the discursive opportunities for radical-right populist politics across Eastern Europe. The articles concentrate on such soft factors as the role of media, the radicalization of public discourse, and the communication repertoires of radical-right populist actors across the region. The contributions em
Some years ago it was decided that a European curriculum should be developed for medical physicists professionally engaged in the support of clinical diagnostic imaging departments. With this in mind, EFOMP (European Federation of Organisations for Medical Physics) in association with ESR (European Society of Radiology) nominated an expert working group. This curriculum is now to hand. The curricu
The Natura 2000 network of protected sites is one of the means to enable biodiversity conservation in Europe. EU member states have to undertake surveillance of habitats and species of community interest protected under the Habitat Directive. Remote sensing techniques have been applied successfully to monitor biodiversity aspects according to Natura 2000, but many challenges remain in assessing dy
The burdens of resource constraints in publicly funded healthcare systems urge decision makers in countries like Sweden, Norway and the UK to find new financial solutions. One proposal that has been put forward is co-payment—a financial model where some treatment or care is made available to patients who are willing and able to pay the costs that exceed the available alternatives fully covered by
Advanced 1-D models for secondary clarifiers aim to incorporate more realism by explicitly accounting for several phenomena that influence the settling process. For each of them a valid mathematical expression needs to be selected to obtain a calibrated model that can be used for operation and control. The presented work evaluates different available expressions for hinderedsettling based on long
The tourism sector has recommitted itself to be ‘climate neutral’ by 2050 through its 2021 Glasgow Declaration: A Commitment to a Decade of Tourism Climate Action. The declared ambition is consistent with the Paris Climate Agreement and net-zero emission targets; however, lacks specific actions by which such a transition might be achieved. The highly influential International Energy Agency (IEA) h
Phylogenetic reconstruction of cancer cell populations remains challenging. There is a particular lack of tools that deconvolve clones based on copy number aberration analyses of multiple tumor biopsies separated in time and space from the same patient. This has hampered investigations of tumors rich in aneuploidy but few point mutations, as in many childhood cancers and high-risk adult cancer. He
Äldreomsorgen är ett fält där det finns kolliderande rättigheter.Rätten till lika omsorg för alla kan vara svår att kombinera med kraven på ett förstå den enskildes behov och att erbjuda individanpassade insatser. Inte minst i frågan om rätten till att kunna utöva sin religion och leva enligt religiösa och kulturella traditioner på ett äldreboende ställs stora krav på både verksamheter och det lok
