Ad hoc networks, being able to organize themselves without user intervention, can easily provide their users with mobility, multimedia support and group communication. However, they have to combine quality of service (QoS) and multicast routing strategies. This article defines the resource management and admission control components of the ad hoc QoS multicast (AQM) routing protocol, which achieve
Background: As a part of a set of reforms launched in 1995, 10 pilot case management services were established in Sweden, which have been subject to an evaluation with regard to outcome and changes in use of services. The present study was designed to provide information about client outcomes over a 6-year follow-up period. Aims: The aim of the study was to investigate changes during the follow-up
BACKGROUND: The primary systemic vasculitides usually associated with autoantibodies to neutrophil cytoplasmic antigens include Wegener's granulomatosis and microscopic polyangiitis. We investigated whether exposure to cyclophosphamide in patients with generalized vasculitis could be reduced by substitution of azathioprine at remission. METHODS: We studied patients with a new diagnosis of generali
BACKGROUND: In patients with atrial septal defect (ASD) the P-wave is prolonged as a marker of delayed atrial conduction which is associated with atrial fibrillation. The study aim was to analyse the impact of ASD closure in adults on P-wave duration and morphology by means of signal-averaged P-waves (PSA-ECG) and to investigate potential mechano-electrical interactions. METHODS: PSA-ECG was obtai
In the wood-to-ethanol process, pretreatment of the material is necessary prior to enzymatic hydrolysis to obtain high overall yields of sugar and ethanol. Steam pretreatment of fast-growing Salix either with or without SO2 impregnation has been investigated by varying different parameters. Overall glucose yields of above 90% and overall xylose yields higher than 80% were obtained both with and wi
This study is a long-term follow-up of a previously published study that used the internet in the rehabilitation of people on long-term sick leave owing to chronic pain and/or burnout. The follow-up was to assess the effects over time of this kind of rehabilitation. The goals of the first study were to improve the participants' health and work capacity. Sixty people were randomly assigned to eithe
We present a new density functional theory of ideal polymer fluids, assuming nearest-neighbor bonding constraints. The free energy functional is expressed in terms of end site densities of chain segments and thus has a simpler mathematical structure than previously used expressions using multipoint distributions. This work is based on a formalism proposed by Tripathi and Chapman [Phys. Rev. Lett.
To describe fractures revealed by magnetic resonance imaging (MRI) in a series of skeletally mature patients with radial wrist pain after an acute injury and clinically suspected to have a scaphoid fracture. Additionally, we attempted to assess the diagnostic value of radiographs and computed tomography (CT) in patients with scaphoid and other carpal fractures verified by MRI.
Two different main concepts for the treatment of severe traumatic brain injury have been established during the last 15 years, namely the more conventional concept recommended in well-established guidelines (eg, the US Guideline, European Guideline, Addelbrook's Guideline from Cambridge) on the one hand, and the Lund concept from the University Hospital of Lund, Sweden on the other. Owing to the l
The problem of classifying short atrial fibrillatory segments in ambulatory ECG recordings as being either paroxysmal or persistent is addressed by investigating a robust approach to signal characterization. The method comprises preprocessing, estimation of the dominant atrial frequency for the purpose of controlling the subbands of a filter bank, and computation of the relative subband (harmonics
Popular Abstract in Swedish Utveckling av nya industriella produkter sker allt oftare med hjälp av datormodeller. Dessa modeller beskriver fysiken för respektive produkt, vilket exempelvis kan vara en bil eller ett kraftverk. Med hjälp av modellerna kan en stor del av analyserna på de framtida produkterna ske med hjälp av datorer, varför färre prototyper behöver konstrueras, vilket medför kortare Simulation of coupled dynamical systems, where the subsystems are bundled with their own internal solver, is important in industry. This is due to that in many cases, with complex systems, this is the only viable option. In this setting, the dynamics of each system is hidden and information between subsystems is exchanged through sampled inputs and outputs, a weakly coupled system. While a new ind
To determine if primary hand osteoarthritis (OA) is associated with abnormal bone and anthropometric traits.
BACKGROUND: Childhood pre-B acute lymphoblastic leukemia (ALL) is a bone marrow (BM) derived disease, which often disseminates out of the BM cavity, where malignant cells to a variable degree can be found circulating in the peripheral blood (PB). Normal pre-B cells are absolutely dependent on BM stroma for survival and differentiation. It is not known whether transformed pre-B ALL cells retain any
Conditionally replicative adenovirus (CRAD) represents a promising approach for cancer therapy. Several CRADs controlled by the human telomerase reverse transcriptase promoter have been developed. However, because of their replicative capacity, the importance of cancer specificity for CRADs needs to be further emphasized. In this study, we have developed a novel dual-regulated CRAD, CNHK500-mE, wh
In this paper we will prove the uniqueness of a solution to Helmholtz' equation for two halfspaces of different media in $n$ dimensions. The theorem allows a finite number of bounded inhomogeneities in each half space. The surface separating the half spaces is assumed to be a cone of arbitrary cross section far away from the origin and is furthermore assumed to be smooth. We assume all space to be

A search for the decays of the Higgs and Z bosons to a φ meson and a photon is performed with a pp collision data sample corresponding to an integrated luminosity of 2.7 fb-1 collected at s=13 TeV with the ATLAS detector at the LHC. No significant excess of events is observed above the background, and 95% confidence level upper limits on the branching fractions of the Higgs and Z boson decays to φ
