The MAX IV facility in Lund, Sweden consists of two storage rings for production of synchrotron radiation. The larger 3 GeV ring has been delivering light to the first users since November 2016, while the smaller 1.5 GeV ring is being commissioned. Coupled-Bunch Mode Instabilities (CBMIs) have been observed in both rings, and they have a degrading effect on the beam quality since they increase the
MAX IV and SOLARIS are two synchrotron light sources located in Lund and in Krakow, respectively. A stripline is a standard multi-purpose component that is used in many accelerators and consists of one or multiple electrodes. The currents that are induced by the Lorentz contracted fields of the electron beam at the electrodes can be used for beam diagnostics, or one can excite the electrodes in or
Africa is facing resource problems due to increasing demand combined with potential climate-induced changes in supply. Here we aim to quantify resources in terms of net primary production (NPP [g C m−2 yr−1]) of vegetation in the Sahel region for 2000–2014.Using time series of the enhanced vegetation index (EVI) from MODIS, NPP was estimated for the Sahel region with a 500 × 500 m spatial resoluti
The purpose of this paper is to describe a novel approach to economic evaluation of infrastructure, the benefit analyses in the Swedish high-speed rail project, and to analyse what role these can play in the decision-making process. The reports identify benefits from infrastructure investment at the local level and were intended to assist in making co-financing agreements and as a basis for decisiThe purpose of this paper is to describe a novel approach to economic evaluation of infrastructure, the benefit analyses in the Swedish high-speed rail project, and to analyse what role these can play in the decision-making process.

We will give a short introduction to foreground/background estimation and Hidden Markov fortracking. More information about the topics can be found in the papers listed at the end.
Objective: To explore how persons with late effects of polio experience falls and what strategies they use to manage the consequences of falls. Design: A qualitative study with face-To-face interviews. Data were analysed by systematic text condensation. Participants: Fourteen ambulatory persons (7 women; mean age 70 years) with late effects of polio. Results: Analysis resulted in one main theme, "
Sofisterna, de första retorikteoretikerna, har inget särskilt gott rykte. Enligt våra uppslagsverk betyder sofism medvetet logiskt felslut. I retoriska handböcker brukar benämningen sofister användas för ett antal retoriskt intresserade lärare och tänkare från antikens Grekland. Det är enligt forskare på området lite oegentligt att tala om sofister, som om det vore någon enhetlig rörelse, vilket d
Reference Attribute Grammars (RAGs) is a declarative executable formalism used for constructing compilers and related tools. Existing implementations support concurrent evaluation only with global evaluation locks. This may lead to long latencies in interactive tools, where interactive and background threads query attributes concurrently.We present lock-free algorithms for concurrent attribute eva
Cancer cells reside in a complex microenvironment comprising stromal cells and immune cells embedded in an extracellular matrix (ECM). Early on in tumor progression, cells reach a critical volume beyond which blood supply is impaired, leading to a decrease in oxygen levels (hypoxia) and nutrient supply. This situation triggers a stress response characterized by a metabolic switch to glycolysis, wh
BACKGROUND: Body height has been associated with an increased risk of venous thromboembolism (VTE), but the association can be confounded with shared familial factors (genetic/environmental). A cosibling design is useful for deeper understanding about the relationship between VTE and height.METHODS AND RESULTS: From Swedish national registry databases, we used a corelative design with full sibling
BACKGROUND: Klinefelter syndrome (KS) is the most common sex chromosome disorder. The genetic background is the extra X chromosome. Venous thromboembolism (VTE) has been observed among KS patients. The aim of the present study was to examine whether KS is associated with VTE.METHODS AND RESULTS: We followed up all hospital in- and outpatients (N=1085) in Sweden with a diagnosis of KS between Janua
Background:Due to new legislation in 2011 and 2013, the Swedish public healthcare system has undergone change as regards incident reporting and supervision. Focus has turned to learning from adverse events and sharing this learning with actors within the system. The aim of this study was to explore with what underlying safety ontology adverse events in the incident reporting system are investigate
One classic approach to real-time object detection is to use adaboost to a train a set of look up tables of discrete features. By utilizing a discrete feature set, from features such as local binary patterns, efficient classifiers can be designed. However, these classifiers include interpolation operations while scaling the images over various scales. In this work, we propose the use of real value
