This paper presents the application of a variety of techniques to study jet substructure. The performance of various modified jet algorithms, or jet grooming techniques, for several jet types and event topologies is investigated for jets with transverse momentum larger than 300 GeV. Properties of jets subjected to the mass-drop filtering, trimming, and pruning algorithms are found to have a reduce
In experimental design and 3D reconstruction it is desirable to minimize the number of observations required to reach a prescribed estimation accuracy. Many approaches in the literature attempt to find the next best view from which to measure, and iterate this procedure. This paper discusses a continuous optimization method for finding a whole set of future imaging locations which minimize the rec
Background: The L68Q variant of cystatin C is highly amyloidogenic forming aggregates in individuals with HCCAA. Results: Spermatozoa from mice expressing human L68Q cystatin C exhibit fertility defects and increased levels of amyloid. Conclusion: L68Q epididymal fluid containing cystatin C amyloid is harmful for sperm function. Significance: Amyloid in the reproductive tract may contribute to mal
In this paper, we describe a novel approach to create 3D miniatures of persons using a Kinect sensor and a 3D color printer. To achieve this, we acquire color and depth images while the person is rotating on a swivel chair. We represent the model with a signed distance function which is updated and visualized as the images are captured for immediate feedback. Our approach automatically fills small
Species of Eunicida (polychaetous annelids) have complex jaw apparatuses with ventral mandibles growing throughout life, but dorsal maxillae undergoing successive moulting episodes. Jaw ontogeny was studied in the eunicid Marphysa fauchaldi, from the appearance of the mandibles and larval maxillae through two moults during the transformation to juvenile and sub-adult maxillae. Although larval maxi
Recent technological innovation has opened new avenues in migration research - for instance, by allowing individual migratory animals to be followed over great distances and long periods of time, as well as by recording physiological information. Here, we focus on how technology - specifically applied to bird migration - has advanced our knowledge of migratory connectivity, and the behavior, demog
BACKGROUND: /st>Previous research suggests that the World Health Organization Surgical Safety Checklist time-out reduces communication failures and medical complications and supports development of better safety attitudes. Previous research also indicates that different values can affect the implementation of interventions. OBJECTIVE: /st>To investigate the actual usage of the checklist in practic
We introduce a multi-region model for simultaneous segmentation of medical images. In contrast to many other models, geometric constraints such as inclusion and exclusion between the regions are enforced, which makes it possible to correctly segment different regions even if the intensity distributions are identical. We efficiently optimize the model using a combination of graph cuts and Lagrangia
The performance of new firms is important for economic development but research has produced limited knowledge about the key relationships among growth, profitability, and survival for new firms. Based on evolutionary theory, we develop a model about how new firms resolve uncertainty about their ability to prosper in a market by monitoring changes in profitability. Our model predicts selection pre
The aim of this article is to reach a deeper understanding of women's decision-making process regarding non-attendance at mammography screenings. The article also discusses the health care social workers' role in providing support to women during this decision. Eighteen qualitative semi-structured interviews were conducted with women who had abstained from mammography screening in Malmö, Sweden. T
Systematic background radiation variations can lead to both false positives and failures to detect an orphan source when searching using car-borne mobile gamma-ray spectrometry. The stochastic variation at each point is well described by Poisson statistics, but when moving in a background radiation gradient the mean count rate will continually change, leading to inaccurate background estimations.
Functional analysis of quantitative expression data is becoming common practice within the proteomics and transcriptomics fields; however, a gold standard for this type of analysis has yet not emerged. To grasp the systemic changes in biological systems, efficient and robust methods are needed for data analysis following expression regulation experiments. We discuss several conceptual and practica
The development of a forest stand in south-eastern Norway during the last 9000 years is investigated by pollen and charcoal analyses. The aims are to identify factors that have influenced current biodiversity, which includes the lichen Usnea longissima, and examine the immigration and establishment of the current dominant tree Picea abies. Fire has been a variable but major disturbance factor at t
An increasing body of evidence suggests that a low-glycaemic-index (GI) diet has a therapeutic as well as a preventive potential in relation to the insulin resistance syndrome. The implementation of a low-GI diet, however, will require an extended list of low-GI foods to be available on the market. The tailoring of low-GI bread products offers a particular challenge due to their generally high GI
Background The design of the Exeter stem may facilitate distal migration, but radiostereometric analysis (RSA) studies have been limited to 2 years of follow-up. Patients and methods We followed migration of the Exeter femoral stems in 22 primary hip arthroplasties for 5 years with RSA. Results All stems migrated distally and the median migration at 2 years was 1.34 mm, while at 5 years it was 1
Abstract in Norwegian Bakgrunn. Fallulykker er et viktig helseproblem hos eldre. Både balansetesting og registrering av egenrapportert funksjon kan være måter å forutse fremtidige ulykker på. Materiale og metode. I en kohortstudie ble egenrapportert gangfunksjon kartlagt hos 307 tilfeldig utvalgte hjemmeboende kvinner 75 år og eldre. Kvinnene gjennomgikk også testing av balanse og gangfunksjon, oBACKGROUND: Falls represent an important health problem among the elderly. Balance testing as well as registration of self-reported balance problems may be appropriate in order to predict the risk of future falls. MATERIALS AND METHODS: Self-reported walking was assessed in 307 randomly selected women 75 years or older living at home. The women underwent testing of gait and balance and were follow
Background and Purpose: Currently, only 4.4% of the forested area in Croatia has been mapped in terms of the critical load of acidity, with exceedances reported for a couple of sites in the region of Gorski Kotar However, some sensitive areas such as the eastern part of Croatia, have not yet been mapped and as a result the exceedance of the critical load of acidity could be much larger than the on
We present numerical simulations that reproduce the salient features of the amazingly strong [Fe ii andFe ii emission spectra in the B and D Weigelt blobs of Carinae. For our studies we have used spectraobtained during the 1998 epoch observations with the Hubble Space Telescope (HST). The spectrum of the Band D Weigelt blobs dominates in [Fe ii and Fe ii emission lines. The same observations show
ABSTRACT Aims: To compare two versions of a questionnaire translated using forward-backward (FB) translation and dual-panel (DP) methodologies regarding preference of wording and psychometric properties. Methods: The Rheumatoid Arthritis Quality of Life instrument was adapted into Swedish by two independent groups using FB and DP methodologies, respectively. Seven out of thirty resulting items wer
