  • Metadata standards and practices in related disciplines and standards for linking different sources : DELIVERABLE D7.6 - Data without Boundaries (DwB) WORK PACKAGE 7 - Standards Development
  • 2015
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Standards development is a key concern for system and infrastructure development when the goal is to support interdisciplinary research by providing access to data from different sources and disciplines for re-use to improve the knowledge base. Metadata is a key concept in the development of better data access as well as to communicate knowledge about discipline specific data to a wider research community to improve the analysis potential of standard data sources like statistical or survey data hosted by NSIs, DAs or universities. This report begins by investigating options and practises to foster extension of existing metadata, applying research data and results e.g. from health and geospatial research disciplines. Secondly the report describes concepts, standards and practices linking data, publication and further research assets to create rich contextual metadata sources. Both facets of metadata are of relevance for interdisciplinary re-use of available data to innovate answers to research questions using different data sources in a rich data and metadata environment. The audience for this report are statistical institutes, data archives and metadata experts with interests in standards development to foster data re-use and knowledge discovery.

  • Structural trends in atomic nuclei from laser spectroscopy of tin
  • 2020
  • Ingår i: Communications Physics. - : Springer Nature. - 2399-3650. ; 3:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Tin is the chemical element with the largest number of stable isotopes. Its complete proton shell, comparable with the closed electron shells in the chemically inert noble gases, is not a mere precursor to extended stability; since the protons carry the nuclear charge, their spatial arrangement also drives the nuclear electromagnetism. We report high-precision measurements of the electromagnetic moments and isomeric differences in charge radii between the lowest 1/2(+), 3/2(+), and 11/2(-) states in Sn117-131, obtained by collinear laser spectroscopy. Supported by state-of-the-art atomic-structure calculations, the data accurately show a considerable attenuation of the quadrupole moments in the closed-shell tin isotopes relative to those of cadmium, with two protons less. Linear and quadratic mass-dependent trends are observed. While microscopic density functional theory explains the global behaviour of the measured quantities, interpretation of the local patterns demands higher-fidelity modelling. Measurements of the hyperfine structure of chemical elements isotopes provide unique insight into the atomic nucleus in a nuclear model-independent way. The authors present collinear laser spectroscopy data obtained at the CERN ISOLDE and measure hyperfine splitting along a long chain of odd-mass tin isotopes.

  • Integrated and differential fiducial cross-section measurements for the vector boson fusion production of the Higgs boson in the H → WW* → eνμν decay channel at 13 TeV with the ATLAS detector
  • 2023
  • Ingår i: Physical Review D. - : AMER PHYSICAL SOC. - 2470-0010 .- 2470-0029. ; 108:7
  • Tidskriftsartikel (refereegranskat)abstract
    • The vector-boson production cross section for the Higgs boson decay in the H→WW*→eνμν channel is measured as a function of kinematic observables sensitive to the Higgs boson production and decay properties as well as integrated in a fiducial phase space. The analysis is performed using the proton-proton collision data collected by the ATLAS detector in Run 2 of the LHC at √s=13  TeV center-of-mass energy, corresponding to an integrated luminosity of 139  fb−1. The different flavor final state is studied by selecting an electron and a muon originating from a pair of W bosons and compatible with the Higgs boson decay. The data are corrected for the effects of detector inefficiency and resolution, and the measurements are compared with different state-of-the-art theoretical predictions. The differential cross sections are used to constrain anomalous interactions described by dimension-six operators in an effective field theory.

  • Luminosity determination in pp collisions at √s=13 TeV using the ATLAS detector at the LHC
  • 2023
  • Ingår i: European Physical Journal C. - : Institute for Ionics. - 1434-6044 .- 1434-6052. ; 83:10
  • Tidskriftsartikel (refereegranskat)abstract
    • The luminosity determination for the ATLAS detector at the LHC during Run 2 is presented, with pp collisions at a centre-of-mass energy s=13 TeV. The absolute luminosity scale is determined using van der Meer beam separation scans during dedicated running periods in each year, and extrapolated to the physics data-taking regime using complementary measurements from several luminosity-sensitive detectors. The total uncertainties in the integrated luminosity for each individual year of data-taking range from 0.9% to 1.1%, and are partially correlated between years. After standard data-quality selections, the full Run 2 pp data sample corresponds to an integrated luminosity of 140.1 ± 1.2 fb - 1 , i.e. an uncertainty of 0.83%. A dedicated sample of low-pileup data recorded in 2017–2018 for precision Standard Model physics measurements is analysed separately, and has an integrated luminosity of 338.1 ± 3.1 pb - 1 . © 2023, The Author(s).

  • Measurement of the Sensitivity of Two-Particle Correlations in pp Collisions to the Presence of Hard Scatterings
  • 2023
  • Ingår i: Physical Review Letters. - : American Physical Society. - 0031-9007 .- 1079-7114. ; 131:16
  • Tidskriftsartikel (refereegranskat)abstract
    • A key open question in the study of multiparticle production in high-energy pp collisions is the relationship between the “ridge”—i.e., the observed azimuthal correlations between particles in the underlying event that extend over all rapidities—and hard or semihard scattering processes. In particular, it is not known whether jets or their soft fragments are correlated with particles in the underlying event. To address this question, two-particle correlations are measured in pp collisions at √s=13  TeV using data collected by the ATLAS experiment at the LHC, with an integrated luminosity of 15.8  pb−1, in two different configurations. In the first case, charged particles associated with jets are excluded from the correlation analysis, while in the second case, correlations are measured between particles within jets and charged particles from the underlying event. Second-order flow coefficients, v2, are presented as a function of event multiplicity and transverse momentum. These measurements show that excluding particles associated with jets does not affect the measured correlations. Moreover, particles associated with jets do not exhibit any significant azimuthal correlations with the underlying event, ruling out hard processes contributing to the ridge.

  • Observation of Single-Top-Quark Production in Association with a Photon Using the ATLAS Detector
  • 2023
  • Ingår i: Physical Review Letters. - : American Physical Society (APS). - 0031-9007 .- 1079-7114. ; 131:18
  • Tidskriftsartikel (refereegranskat)abstract
    • This Letter reports the observation of single top quarks produced together with a photon, which directly probes the electroweak coupling of the top quark. The analysis uses 139  fb−1 of 13 TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider. Requiring a photon with transverse momentum larger than 20 GeV and within the detector acceptance, the fiducial cross section is measured to be 688±23(stat) , to be compared with the standard model prediction of at next-to-leading order in QCD.

  • Early disturbance of microvascular function precedes chemotherapy-induced intestinal injury
  • 2005
  • Ingår i: Dig Dis Sci. - : Springer Science and Business Media LLC. - 0163-2116. ; 50:9, s. 1729-33
  • Tidskriftsartikel (refereegranskat)abstract
    • Intestinal injury 4-48 hr after cytotoxic therapy (etoposide phosphate, 100 mg/kg body weight [bw], intravenously [i.v.]) was studied in rats using ligated intestinal loops. Chromium-51 ethylenediaminetetraacetic acid ((51)Cr-EDTA) and rubidium-86 chloride ((86)RbCl) were deposited intraluminally to determine the extent of the increase in intestinal permeability and ion channel disruption. Evans Blue (EB) was used for detection of endothelial leakage. Intestinal morphology was documented. Endothelial dysfunction, as observed by an increased extravasation of EB, was evident already 4 hr after cytotoxic therapy. Intestinal epithelial injury, as observed by an increase in (51)Cr-EDTA permeation and a decrease in (86)Rb absorption, occurred after 48 hr. Finally, histology disclosed a reduced crypt cell proliferation, displayed as a decrease in Ki67-positive cells. The findings suggest that, in the development of intestinal injury after cytotoxic therapy, endothelial disruption is an early event, whereafter epithelial dysfunction and crypt stem cell arrest occur. This knowledge could be of importance in the design of future intervention trials.

  • Achievements and experiences from science–policy interaction in the field of air pollution : Synthesising 20 years of research and outreach,thinking about future needs
  • 2021
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • For 20 years, the Swedish Environmental Protection Agency together with the MISTRA research foundation have funded five air pollution research programmes with focus on producing knowledge that supports policy and emission control in national and international arenas. The research has been multidisciplinary and has included research on emissions, atmospheric transport and transformation processes, human health effects, ecosystem effects, and emission control strategies. Research has also been conducted on the interaction between air pollution and climate change.Over these years, the link between the research programmes and the development of emission control strategies and policies in Sweden, the EU, and the UNECE Air Convention has been of high importance. This report presents how the research programmes have created societal benefits through support for the development of air pollution policies and emission control measures. The report also identifies future research needs to ensure continued progress towards even better air quality for future generations.

  • 2015
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • The present Deliverable (1.3) comprises of two joint reports: former Deliverable 1.3 (User Requirements and Case Studies report) and Deliverable 1.6 (Content Strategy Report). As a product of a multi-scale, interdisciplinary effort, Deliverable 1.3 (User Requirements and Case Studies report / Content Strategy Report) employs a multi-faceted approach to make sense of the information needs and behaviour of Humanities and Social Sciences researchers both within and outside the Europeana ecosystem, while achieving profound understanding of the ways these communities interact with existing Europeana content and metadata. Through extensive and widely-levelled empirical research (Case Studies, Web Survey, Interviews, Focus Groups) complimented by thorough desk research (Literature review, study of particular thematic areas), and building on work previously conducted in the context of other Digital Humanities Research Infrastructures (DARIAH, EHRI, ARIADNE, NeDiMAH) Work Package 1 managed to reach a long list of non-prioritized User Requirements as well as a set of flexible Content Recommendations for the upcoming development of Europeana Research.

  • High performance thin layer chromatography (HPTLC), an improved technique for screening lichen substances.
  • 1993
  • Ingår i: The Lichenologist. - : Cambridge University Press (CUP). - 0024-2829 .- 1096-1135. ; 25, s. 61-71
  • Tidskriftsartikel (refereegranskat)abstract
    • High performance thin layer chromatography (HPTLC) is a method that can be used for screening lichen substances. It is as simple to use as standard TLC, but has many advantages: It is more sensitive, it is possible to run more samples in a shorter period of time, and the amount of solvent used is much smaller. The material needed and the methods used are described in detail. Horizontal chromatogram development was used. Since two of the solvents used in system B have been substituted, and since the properties of the HPTLC plates are slightly different, our results are not entirely in accordance with the standardized TLC method. A revised table for the identification of 69 lichen substances (obtained from 62 taxa) is accordingly presented.

    • On 19 July 2009 Ingvar Kärnefelt celebrated his 65th birthday. This could have meant that we, his former students, would be celebrating him in his retirement from his position as head of the Biological Museums at Lund University. We are grateful that this is not the case, as Ingvar will carry on, probably for at least one or two more years. Instead, we celebrate Ingvar because he is the main reason for all of us having studied lichenology in Lund. This special issue of The Lichenologist is dedicated to him as a birthday tribute in honour of his long and fruitful lichenological career. The main authors of all the papers in this issue are former students of Ingvar. For several of us he has not only acted as supervisor but later also as the director of the Botanical Museum where we meet him in our daily work.

  • The sister group relation of Parmeliaceae (Lecanorales, Ascomycota)
  • 2007
  • Ingår i: Mycologia. - : Informa UK Limited. - 0027-5514 .- 1557-2536. ; 99:1, s. 42-49
  • Tidskriftsartikel (refereegranskat)abstract
    • The family Parmeliaceae (Lecanorales, Ascomycota) is possibly the largest, best known and most thoroughly studied lichen family within its order. Despite this fact the relationship between Parmeliaceae and other groups in Lecanorales is still poorly known. The aim of the present study is to contribute to finding the sister group of Parmeliaceae as an aid in future studies on the phylogeny and character evolution of the group. We do this by sampling all potential relatives to the Parmeliaceae that we have identified, i.e. Cypsoplaca, Japewia, Mycoblastus, Protoparmelia, and Tephromela, a good representation of the major groups within the Parmeliaceae s. lat. and a good representation of other taxa in the core Lecanorales. We use molecular data from two genes, the large subunit of the nuclear ribosomal RNA gene (nrLSU) and the small subunit of the mitochondrial ribosomal RNA gene (mrSSU), and a Bayesian analysis of the combined data. The results show that the closest relatives to Parmeliaceae are the two genera Protoparmelia and Gypsoplaca, which are crustose lichens. Parmeliaceae in our sense is a well supported group, including also the family segregates Alectoriaceae, Hypogymniaceae, Usneaceae and Anziaceae.

  • Neural Lineage Progression Controlled by a Temporal Proliferation Program.

    • Great progress has been made in identifying transcriptional programs that establish stem cell identity. In contrast, we have limited insight into how these programs are down-graded in a timely manner to halt proliferation and allow for cellular differentiation. Drosophila embryonic neuroblasts undergo such a temporal progression, initially dividing to bud off daughters that divide once (type I), then switching to generating non-dividing daughters (type 0), and finally exiting the cell cycle. We identify six early transcription factors that drive neuroblast and type I daughter proliferation. Early factors are gradually replaced by three late factors, acting to trigger the type I→0 daughter proliferation switch and eventually to stop neuroblasts. Early and late factors regulate each other and four key cell-cycle genes, providing a logical genetic pathway for these transitions. The identification of this extensive driver-stopper temporal program controlling neuroblast lineage progression may have implications for studies in many other systems.less thanbr /greater than (Copyright © 2017 Elsevier Inc.

  • Specification of neuronal identities by feedforward combinatorial coding.
  • 2007
  • Ingår i: PLoS biology. - : Public Library of Science (PLoS). - 1544-9173 .- 1545-7885. ; 5:2, s. 0295-0308
  • Tidskriftsartikel (refereegranskat)abstract
    • Neuronal specification is often seen as a multistep process: earlier regulators confer broad neuronal identity and are followed by combinatorial codes specifying neuronal properties unique to specific subtypes. However, it is still unclear whether early regulators are re-deployed in subtype-specific combinatorial codes, and whether early patterning events act to restrict the developmental potential of postmitotic cells. Here, we use the differential peptidergic fate of two lineage-related peptidergic neurons in the Drosophila ventral nerve cord to show how, in a feedforward mechanism, earlier determinants become critical players in later combinatorial codes. Amongst the progeny of neuroblast 5-6 are two peptidergic neurons: one expresses FMRFamide and the other one expresses Nplp1 and the dopamine receptor DopR. We show the HLH gene collier functions at three different levels to progressively restrict neuronal identity in the 5-6 lineage. At the final step, collier is the critical combinatorial factor that differentiates two partially overlapping combinatorial codes that define FMRFamide versus Nplp1/DopR identity. Misexpression experiments reveal that both codes can activate neuropeptide gene expression in vast numbers of neurons. Despite their partially overlapping composition, we find that the codes are remarkably specific, with each code activating only the proper neuropeptide gene. These results indicate that a limited number of regulators may constitute a potent combinatorial code that dictates unique neuronal cell fate, and that such codes show a surprising disregard for many global instructive cues.

  • Reflecting on and Refracting User Needs through Case Studies in the Light of Europeana Research
  • 2016
  • Ingår i: Digital Humanities 2016, 11-16 juli, 2016, Krakow, Polen.
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • This poster presents work on documenting user needs in the Humanities and Social Sciences as illustrated through Case Studies in the context of the Europeana Cloud “Unlocking Europe's Research via the Cloud” project. Conducted as part of a wider methodological effort including desk research, expert fora and a web survey, methodology and findings of actual use of innovative digital tools and services will be visually represented. This work will form the basis of the Europeana Research Case Studies which will seek to gather and process an evidence-based record of the information practices, needs and scholarly methods in the respective communities. This poster reports on collaborative, cross-European work conducted during 2013-2015 in the context of the Europeana Cloud “Unlocking Europe's Research via the Cloud” project, and touches upon planned activities in the context of Europeana Research in 2016. Europeana Research is an initiative which aims to create stronger links between the cultural heritage sector and academia. More particularly, it aims to ensure that open, high-quality data from the cultural sector is available for reuse by the digital humanities community. One of the main objectives of Europeana Cloud was the enhancement of the understanding of digital tools, research processes and scholarly content used in the Humanities and Social Sciences, thus informing the development of tools and aggregation of content in Europeana for research purposes. To this end, and in order to contribute towards the development of the new platform of Europeana Research, Case Studies were developed as part of a wider methodological effort which included desk research, expert fora and web survey for reaching user requirements. The purpose of this poster is to visually represent the methodology followed and results reached in documenting actual use of innovative digital tools and services in the Humanities and Social Sciences research communities illustrated in three main Case Studies in the disciplines of Education, Art History and Sociology, and further complemented by satellite cases. The Case Studies were initially selected based on the disciplines and tools that might best make use of current Europeana content. By defining “innovative” as “either performing functions that were previously unavailable, or performing already available functions in a qualitatively different way”, three tools were identified as best fitting this criteria (Transana, HyperImage, NodeXL) enriched by two “satellite” tools more frequently used in the respective research disciplines (NVivo, Voyant). These were further approached following a threefold methodology of semi-structured interviews, empirical observation of the tools and background research. The results were then discussed both from the perspective of the discipline area, and through the lens of the scholarly primitives (Unsworth 2000, Palmer et al 2009), to determine their use with Europeana content. The poster will also highlight the importance of accessibility of data for research infrastructures and research groups and need to focus on high quality metadata and content both for Europeana Research and the wider GLAM sector, and will illustrate how digital tools are not themselves a guarantee of good research, as researchers do not necessarily use the same digital tool throughout the research process; rather they use one tool per step (one tool = one research primitive). This poster will also present future work planned to be undertaken in the context of Europeana Research in 2016. Based on Europeana Cloud, a series of new Case Studies will be developed and expanded towards different research communities. The Europeana Research Case Studies will be undertaken in collaboration with existing European research initiatives, and will seek to gather and process an evidence-based record of the information practices, needs and scholarly methods of arts and humanities and social sciences researchers within the broad Europeana ecosystem and particularly in relation to Europeana content. Τhe Case Studies will employ a mixed methods approach combining various ways of gathering empirical evidence on the information needs and scholarly methods employed in digitally-enabled arts and humanities and social sciences research across Europe and beyond.

  • State of the art report on digital research practices, tools and scholarly content use : Deliverable D1.2
  • 2013
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • This document constitutes desk research to analyse the current situation related to digital research practices, tools and content for the humanities and social sciences research communities and it comprises of three Milestones submitted separately in the course of the first nine months of the Project, each corresponding to digital research practices, tools and content respectively. Moreover, this report will serve as an exploratory stage which will provide the basis for the confirmation stage, that is the web survey undertaken within Task 1.3, relying heavily on work previously presented in Deliverable 1.1 (Research Communities Identification and Definition Report), in which the humanities and social sciences research communities were largely identified. The Research Communities Web Survey (T.1.3.4), which has been completed and is currently being processed, encompasses - amongst others -questions pertaining to the activities undertaken by Humanities and Social Sciences researchers, as well as questions regarding the use of content and metadata. This current document provides the background work which guided the design of the Web Survey and is meant to complement the related Web Survey findings which will comprise the User Requirements and Case Studies Analysis report, D1.3. Moreover, this work draws from and complements Deliverable 1.5 (Case Studies Expert Forum Report. The present desk research seeks to analyse the current situation related to digital research practices, tools and content for the humanities and social sciences research community, and will serve as an exploratory stage which will provide the basis for the confirmatory stage, that is the Content Strategy and User Requirements reports, due later on in the Project.

  • Energy structure and transition rates in the Ne-like sequence from relativistic CI calculations
  • 2012
  • Ingår i: Europhysics Conference Abstracts;36C. - : European Physical Society. ; , s. 128-128
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Atomic data are important in astrophysical applications and transition rates can be used in the determination of element abundances and plasma diagnostics. To provide for the extensive data needs a number of general computer codes such as SUPERSTRUCTURE, CIV3, and ATSP2K have been developed. As an alternative to these codes, which all rely on the Breit-Pauli approximation, the fully relativistic GRASP2K code can be used. GRASP2K is based on the multiconfiguration Dirac-Hartree-Fock method and implements a bi-orthogonal transformation method that permits initial and final states in a transition array to be optimized separately, which, in many cases, leads to more accurate values of the resulting rates. The GRASP2K package also contains modules to compute diagonal and off-diagonal hyperfine interaction constants, isotope shifts, Land´e gJ factors, and splittings of magnetic sub-state in intermediate and strong magnetic fields. In this work, GRASP2K has been applied to provide highly accurate spectroscopic data for ions in the Ne-like sequence between Mg III and Kr XXVII. Valence, core-valence, and core-core correlation effects were accounted for through SD-MR expansions to increasing sets of active orbitals. In Mg III, Al IV, Si V, P VI, S VII, and Ar IX, for which experimental energies are known to high accuracy, the mean error in the calculated energies is only 0.011%. For ions with no available experimental energy levels the calculated values should be most valuable in various applications. The high accuracy of the calculated energies makes it possible, in some cases, to to point out experimental values that are in error. Babushkin (length) and Coulomb (velocity) forms of transition rates are computed and agree to within a few percent for the majority of the allowed transitions. Computed lifetimes for states belonging to the 2p33s and 2p53d configurations are in good agreement with values from beam-foil measurements as well as from accurate MCHF Breit-Pauli calculations.

  • Protein Detection Using the Multiplexed Proximity Extension Assay (PEA) from Plasma and Vaginal Fluid Applied to the Indicating FTA Elute Micro Card™
  • 2016
  • Ingår i: Journal of Circulating Biomarkers. - : SAGE Publications. - 1849-4544. ; 5
  • Tidskriftsartikel (refereegranskat)abstract
    • The indicating FTA elute micro card? has been developed to collect and stabilize the nucleic acid in biological samples and is widely used in human and veterinary medicine and other disciplines. This card is not recommended for protein analyses, since surface treatment may denature proteins. We studied the ability to analyse proteins in human plasma and vaginal fluid as applied to the indicating FTA elute micro card? using the sensitive proximity extension assay (PEA). Among 92 proteins in the Proseek Multiplex Oncology Iv2 panel, 87 were above the limit of detection (LOD) in liquid plasma and 56 among 92 above LOD in plasma applied to FTA cards. Washing and protein elution protocols were compared to identify an optimal method. Liquid-based cytology samples showed a lower number of proteins above LOD than FTA cards with vaginal fluid samples applied. Our results demonstrate that samples applied to the indicating FTA elute micro card? are amendable to protein analyses, given that a sensitive protein detection assay is used. The results imply that biological samples applied to FTA cards can be used for DNA, RNA and protein detection.

  • Dual-headed Coincidence PET vs. Dedicated PET/CT in the Evaluation of Thoracic Malignancies
  • 2010
  • Ingår i: In Vivo. - 0258-851X .- 1791-7549. ; 24:2, s. 235-238
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study was to evaluate the usefulness of coincidence PET imaging as compared with dedicated PET/CT in cancer staging. Patients and Methods: Sixteen patients with thoracic malignancies referred to a PET/CT examination accepted to repeat the acquisition with a coincidence PET system. One experienced nuclear medicine physician compiled a report from the PET/CT examinations and the coincidence PET images. The reports were compared and evaluated according to the degree of agreement: no agreement, unsatisfactory, acceptable or satisfying agreement. Results: Satisfying or acceptable agreement between the PET/CT and the coincidence PET examination was found in 14 out of 16 patients (88%). The main issue for the examining physician was to anatomically locate the FDG uptake in the mediastinum in The coincidence PET images. Conclusion: The data from this small study imply that the staging results obtained with coincidence PET are in most cases concordant with those obtained with dedicated PET/CT.

  • Tidskriftsartikel (refereegranskat)abstract
    • Research on assessing a group’s maturity in data-driven culture is rare and fragmented. This article investigates how maturity in data-driven culture can be assessed from a historical perspective. A case study was done on how the Education Council evolved in analytics maturity and as a group during 2014-2023. The assessment showed that the Education Council experienced both successful progression of group development and usage of analytics, as well as regression in group development and analytics usage. The practical implications of the findings are that group leaders need to be aware of the interplay between analytics usage and group development when planning to improve their group’s maturity in data-driven culture.

  • Radical prostatectomy versus watchful waiting in localized prostate cancer : the Scandinavian prostate cancer group-4 randomized trial
  • 2008
  • Ingår i: Journal of the National Cancer Institute. - : Oxford University Press. - 0027-8874 .- 1460-2105. ; 100:16, s. 1144-1154
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The benefit of radical prostatectomy in patients with early prostate cancer has been assessed in only one randomized trial. In 2005, we reported that radical prostatectomy improved prostate cancer survival compared with watchful waiting after a median of 8.2 years of follow-up. We now report results after 3 more years of follow-up.METHODS: From October 1, 1989, through February 28, 1999, 695 men with clinically localized prostate cancer were randomly assigned to radical prostatectomy (n = 347) or watchful waiting (n = 348). Follow-up was complete through December 31, 2006, with histopathologic review and blinded evaluation of causes of death. Relative risks (RRs) were estimated using the Cox proportional hazards model. Statistical tests were two-sided.RESULTS: During a median of 10.8 years of follow-up (range = 3 weeks to 17.2 years), 137 men in the surgery group and 156 in the watchful waiting group died (P = .09). For 47 of the 347 men (13.5%) who were randomly assigned to surgery and 68 of the 348 men (19.5%) who were not, death was due to prostate cancer. The difference in cumulative incidence of death due to prostate cancer remained stable after about 10 years of follow-up. At 12 years, 12.5% of the surgery group and 17.9% of the watchful waiting group had died of prostate cancer (difference = 5.4%, 95% confidence interval [CI] = 0.2 to 11.1%), for a relative risk of 0.65 (95% CI = 0.45 to 0.94; P = .03). The difference in cumulative incidence of distant metastases did not increase beyond 10 years of follow-up. At 12 years, 19.3% of men in the surgery group and 26% of men in the watchful waiting group had been diagnosed with distant metastases (difference = 6.7%, 95% CI = 0.2 to 13.2%), for a relative risk of 0.65 (95% CI = 0.47 to 0.88; P = .006). Among men who underwent radical prostatectomy, those with extracapsular tumor growth had 14 times the risk of prostate cancer death as those without it (RR = 14.2, 95% CI = 3.3 to 61.8; P < .001).CONCLUSION: Radical prostatectomy reduces prostate cancer mortality and risk of metastases with little or no further increase in benefit 10 or more years after surgery.

  • PIP degron-stabilized Dacapo/p21(Cip)(1) and mutations in ago act in an anti- versus pro-proliferative manner, yet both trigger an increase in Cyclin E levels
  • 2019
  • Ingår i: Development. - : COMPANY BIOLOGISTS LTD. - 0950-1991 .- 1477-9129. ; 146:13
  • Tidskriftsartikel (refereegranskat)abstract
    • During cell cycle progression, the activity of the CycE-Cdk2 complex gates S-phase entry. CycE-Cdk2 is inhibited by CDK inhibitors (CKIs) of the Cip/Kip family, which include the human p21(Cip)(1) and Drosophila Dacapo (Dap) proteins. Both the CycE and Cip/Kip family proteins are under elaborate control via protein degradation, mediated by the Cullin-RING ligase (CRL) family of ubiquitin ligase complexes. The CRL complex SCFFoxw7/Ago targets phosphorylated CycE, whereas p21(Cip)(1) and Dap are targeted by the CRLCdf2 complex, binding to the PIP degron. The role of CRL-mediated degradation of CycE and Cip/Kip proteins during CNS development is not well understood. Here, we analyse the role of ago (Fbxw7)-mediated CycE degradation, and of Dap and p21(Cip)(1) degradation during Drosophila CNS development. We find that ago mutants display over-proliferation, accompanied by elevated CycE expression levels. By contrast, expression of PIP degron mutant Dap and p21(Cip)(1) transgenes inhibit proliferation. However, surprisingly, this is also accompanied by elevated CycE levels. Hence, ago mutation and PIP degron Cip/Kip transgenic expression trigger opposite effects on proliferation, but similar effects on CycE levels.

  • Randomized Trials of Systemic Medically-treated Malignant Mesothelioma : A Systematic Review
  • 2015
  • Ingår i: Anticancer Research. - 0250-7005 .- 1791-7530. ; 35:5, s. 2493-2501

    • Malignant pleural mesothelioma (MPM) is a rare but aggressive malignancy mainly localized to the pleura. Malignant mesothelioma grows highly invasive into surrounding tissue and has a low tendency to metastasize. The median overall survival (OS) of locally advanced or metastatic disease without treatment is 4-13 months but, during recent years, improvement in survival has been achieved since treatment for patients with mesothelioma has improved with better palliative care, systemic medical treatment, surgery and improved diagnostics methods. The present review aims at describing available data from randomized trials considering systemic medical treatment for this patient category.

  • Cost effectiveness of cardiac resynchronization therapy in the Nordic region : an analysis based on the CARE-HF trial
  • 2008
  • Ingår i: European Journal of Heart Failure. - : Wiley. - 1388-9842 .- 1879-0844. ; 10:9, s. 869-877
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The aim of this study was to investigate the cost-effectiveness of cardiac resynchronization therapy (CRT) in Denmark, Finland and Sweden. The analysis was based on the CARE-HF trial, a randomised clinical trial investigating the efficacy of adding CRT (n=409) to optimal pharmacological treatment (n=404) in patients with moderate to severe heart failure with markers of cardiac dyssynchrony. The average follow-up time was 29.4 months. METHODS: The health effects were measured in terms of quality-adjusted life years (QALYs) gained. Data on health care resource consumption from CARE-HF was combined with costs for CRT implantation and hospitalisation from university hospitals in Denmark, Finland and Sweden. Calculations were based on patients' expected life time. The expected device lifetime (6 years) was used for CRT, and no additional gains in clinical effects were assumed after the 6 years. RESULTS: The cost-effectiveness ratio per QALY gained was 4800 euros in Denmark, 3600 euros in Finland and 6700 euros in Sweden. The 95% confidence intervals for the cost per QALY gained varied between a lower limit of 1169 euros in Finland to an upper limit of 17,482 euros in Sweden. These values were all below the threshold for being cost-effective in Denmark, Finland and Sweden. CONCLUSIONS: The study indicates that CRT is a cost-effective treatment in Scandinavian health care settings compared to traditional pharmacological therapy and can therefore be recommended for routine use in patients with moderate to severe heart failure and markers of dyssynchrony.

  • Statistical Anomaly Detection for Train Fleets
  • 2012. - 9
  • Ingår i: Proceedings of the National Conference on Artificial Intelligence, vol. 3, 2012. - Toronto, Canada. - 9781577355687 ; , s. 2217-2223
  • Konferensbidrag (refereegranskat)abstract
    • We have developed a method for statistical anomaly detection which has been deployed in a tool for condition monitoring of train fleets. The tool is currently used by several railway operators over the world to inspect and visualize the occurrence of "event messages" generated on the trains. The anomaly detection component helps the operators to quickly find significant deviations from normal behavior and to detect early indications for possible problems. The savings in maintenance costs comes mainly from avoiding costly breakdowns, and have been estimated to several million Euros per year for the tool. In the long run, it is expected that maintenance costs can be reduced with between 5 and 10 % by using the tool.

    • CLARIN is a European Research Infrastructure Consortium (ERIC), which aims at (a) making extensive language-based materials available as primary research data to the humanities and social sciences (HSS); and (b) offering state-of-the-art language technology (LT) as an eresearch tool for this purpose, positioning CLARIN centrally in what is often referred to as the digital humanities (DH). The Swedish CLARIN node Swe-Clarin was established in 2015 with funding from the Swedish Research Council.In this paper, we describe the composition and activities of Swe-Clarin, aiming at meeting the requirements of all HSS and other researchers whose research involves using text and speech as primary research data, and spreading the awareness of what Swe-Clarin can offer these research communities. We focus on one of the central means for doing this: pilot projects conducted in collaboration between HSS researchers and Swe-Clarin, together formulating a research question, the addressing of which requires working with large language-based materials. Four such pilot projects are described in more detail, illustrating research on rhetorical history, second-language acquisition, literature, and political science. A common thread to these projects is an aspiration to meet the challenge of conducting research on the basis of very large amounts of textual data in a consistent way without losing sight of the individual cases making up the mass of data, i.e., to be able to move between Moretti’s “distant” and “close reading” modes.While the pilot projects clearly make substantial contributions to DH, they also reveal some needs for more development, and in particular a need for document-level access to the text materials. As a consequence of this, work has now been initiated in Swe-Clarin to meet this need, so that Swe-Clarin together with HSS scholars investigating intricate research questions can take on the methodological challenges of big-data language-based digital humanities.

  • Sources and propagation of eectromagnetic transients in railway systems, S01-3915/08. Final Report
  • 2005
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • The railway system is continuously being updated. Upgrading axle loads, introducing new engines with increasing power needs and advanced motor control give unwanted electromagnetic consequences for electronic-, telecommunication-, and signalling systems along the track. This can, for example, lead to failure in detector systems and traffic control systems and increased cost due to corrective maintenance. This research project was initiated with the purpose of understanding origin and propagation of radiated and conducted electromagnetic transients in the railway system. To investigate the problem of radiated and conducted electromagnetic interference, it has been necessary to develop new measuring methods. Measurements have been conducted to determine if the more sensitive low voltage systems are influenced by higher voltage systems. An existing electromagnetic modeling tool has been utilized, to model crosstalk between the rails and the overhead line catenary system, and modified to incorporate a combination of two- and three- dimensional models to reduce time and space complexity. The resulting simulation environment can be used to analyze possible sources of electromagnetic disturbances in the coexisting signaling circuitry of today, and to reduce the influence of these sources. This gives a new application of the measurement method and further development of a simulation tool. One of the objectives in this project has been to find out the tolerance of the low voltage detector systems in presence of the higher voltage system used in the railways. One of the conclusions is that correct installation is important and that failure to comply with installation procedures results in high electromagnetic interference. There is no correlation between the presence of trains and randomly occurring disturbances.

  • New records, range extensions and nomenclatural innovations for lichens and lichenicolous fungi from Alaska, USA
  • 2012

    • New records, range extensions and nomenclatural innovations for lichens and lichenicolous fungi from Alaska, U.S.A. - Herzogia 25: 177-210. Surveys of lichens and lichenicolous fungi have been taking place in the U.S. state of Alaska for more than 160 years, but until now assessing the full extent of their diversity has been hampered by the lack of a comprehensive and synonymized baseline inventory. In this paper we will begin to redress this by resolving outstanding nomenclatural issues and providing voucher data for a forthcoming catalog of Alaskan lichens, specifically: 1) synonymization,and/or resolution of status of species previously reported from Alaska, with emphasis on Alaskan types; 2) species new to the Alaska lichen biota; and 3) biogeographically significant new records from within Alaska. We report 91 species new to the flora of Alaska, including 65 lichens, three saprophytic calicioid fungi and 23 lichenicolous fungi. Of these, we report thirteen species, Biatora sphaeroidiza, Biatorella conspurcans, Chaenothecopsis arthoniae, Collemopsidium foveolatum, Dactylospora frigida, Halospora discrepans, Lecanora bryopsora, Opegrapha geographicola, Peltigera lyngei, Petractis clausa, Protoblastenia cyclospora, Thelocarpon impressellum and Usnea cylindrica as new to North America. In addition, Arthonia pruinata and Flavocetraria minuscula are new to Canada and Adelococcus alpestris new to the United States. We further place the following five names into synonymy: Lecania disceptans (Nyl.) Lynge [= Halecania alpivaga (Th.Fr.) M.Mayrhofer], Lecidea pallidella Nyl. [= Lecania subfuscula (Nyl.) S.Ekman], Lempholemma triptodes (Nyl.) Zahlbr. Leciophysma finmarkicum Th.Fr.), Polyblastia obtenta (Nyl.) Lynge [= Sporodictyon terrestre (Th.Fr.) S.Savic & Tibell], and Verrucaria pernigrata Nyl. [= Protothelenella sphinctrinoides (Nyl.) H.Mayrhofer & Poelt]. We propose restoring the long overlooked taxon Polyblastia exalbida (Nyl.) Zahlbr., currently known only from Alaska, to the North American lichen checklist. Finally, we propose the new combination Puttea caesia (Fr.) M.Svensson & T.Sprib. to replace Lecidea symmictella Nyl., which becomes a synonym.

  • Do beta-blockers reduce negative intrusive thoughts and anxiety in cancer survivors? – An emulated trial
  • 2024
  • Ingår i: BMC Cancer. - 1471-2407. ; 24:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: High rates of negative intrusivethoughts have been reported among cancer patients. Prevalent users of beta-blocker therapy have reported lower levels of cancer related intrusive thoughts than non-user. The aim of this study is to investigate if initiation of beta-blocker therapy reduces the prevalence and severity of intrusive thoughts (co-primary endpoints) and the prevalence of anxiety, depressed mood, and low quality of life (secondary endpoints) in cancer survivors. Methods: Data on patient-reported outcomes from three cohort studies of Swedish patients diagnosed with colon, prostate or rectal cancer were combined with data on beta-blocker prescriptions retrieved from the Swedish Prescribed Drug Register. Two randomized controlled trials were emulated. Trial 1 had follow-up 1year after diagnosis, trial 2 had follow-up 2years after diagnosis, baseline in both trials was 12months before follow-up. Those who initiated beta-blocker therapy between baseline and follow-up was assigned Active group, those who did not was assigned Control group. All endpoints were analysed using Bayesian ordered logistic regression. Results: Trial 1 consisted of Active group, n = 59, and Control group, n = 3936. Trial 2 consisted of Active group, n = 87, and Control group, n = 3132. The majority of participants were men, 83% in trial 1 and 94% in trial 2. The prevalence and severity of intrusive thoughts were lower in the Active group in trial 1, but no significant differences between groups were found in either trial. The prevalence of depressed mood, worse quality of life and periods of anxiety were higher in the Active group in both trials with significant differences for quality of life in trial 1 and anxiety in trial 2. Conclusions: The emulated trials demonstrated no evidence of a protective effect of beta-blocker therapy against intrusive thoughts. The Active group had reduced quality of life and elevated anxiety compared to the Control group. Trial registration: The three cohort studies were registered at isrctn.com/clinicaltrials.gov (ISRCTN06393679, NCT02530593 and NCT01477229).

  • Ingår i: Acta Oncologica. - : TAYLOR & FRANCIS LTD. - 0284-186X .- 1651-226X. ; 58:7, s. 997-1002
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Childhood cancer survivors treated before 1992, when blood donor screening for hepatitis C virus (HCV) infection was introduced, are at risk of transfusion-transmitted HCV infection. A national HCV screening campaign targeting blood transfusion recipients was launched in Sweden in 2007-2010. The aims of this study were to, among adult childhood cancer survivors in Stockholm County, investigate the prevalence of HCV infection, the natural course of infection, treatment outcome and anti-HCV testing frequency before, during and after the screening campaign and finally to actively screen the untested ones.Material and Methods: This was a combined retrospective register based and prospective screening study of adult childhood cancer survivors (n=686) treated for malignancy in Stockholm before 1992. In the first part, we investigated the prevalence of HCV infection and previous anti-HCV testing, and in the second part, we actively traced and HCV-screened the remaining untested cohort living in Stockholm. Analysis of previous documented anti-HCV tests in medical records, laboratory records, and the national communicable disease registry was performed. In the second part, 231 presumably untested individuals were contacted by mail and offered an anti-HCV test. The natural course of HCV infection and treatment outcome was analyzed for those found to be chronically infected.Results: In total, 235 patients were tested and 11 were HCV-RNA positive. The overall prevalence of chronic HCV infection among the tested childhood cancer survivors was thus 4.7% (95% CI = 2.6-8.2%), which is almost 10 times higher than the national prevalence of 0.5%. Only 12% of the Stockholm cohort were tested during the screening campaign in 2007-2010, while the test uptake using active tracing screening within this study was 40% (p<.001).Conclusion: With today's effective treatment options, active tracing and HCV screening of childhood cancer survivors are recommended.

  • Tidskriftsartikel (refereegranskat)abstract
    • Extensive self-consistent multiconfiguration Dirac-Hartree-Fock (MCDHF) calculations and subsequent relativistic configuration in- teraction calculations are performed for 262 states belonging to the 15 configurations 2s22p2, 2s2p3, 2p4, 2s22p3l, 2s2p23l, 2p33l and 2s22p4l (l = 0,1,2) in selected carbon-like ions from Ar XIII to Zn XXV. Electron correlation effects are accounted for through large configuration state function expansions. Calculated energy levels are compared with existing theoretical calculations and data from the Chianti and NIST databases. In addition, Landé gJ -factors and radiative electric dipole transition rates are given for all ions. The accuracy of the calculations are high enough to facilitate the identification of observed spectral lines.

  • Cost-effectiveness of the Taxus paclitaxel-eluting stent in the Swedish healthcare system
  • 2006
  • Ingår i: Scandinavian Cardiovascular Journal. - : Informa UK Limited. - 1401-7431 .- 1651-2006. ; 40:1, s. 17-24
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To analyse the cost-effectiveness of Taxus compared to a bare-metal stent in patients with coronary artery disease in the Swedish healthcare setting. DESIGN: A decision-analytic model combining clinical data on revascularization rates with Swedish unit costs for medical resources and utility data from the literature. RESULTS: For patients of moderate risk, the average cost per patient at 12 months is 72,200 SEK for Taxus and 66,900 SEK for a bare-metal stent, while the average cost for high risk patients is nearly equivalent (73,000 vs. 71,700 SEK). The cost per revascularization avoided is generally favourable, while the incremental cost per QALY gained varies depending on the assumptions made; from 2,351,000 SEK for patients of moderate risk at 12-months to cost saving at 24 months for high risk patients. Budget impact scenarios at 12 months are cost-neutral. CONCLUSION: The Taxus stent is cost-effective in high risk patients, particularly at 24 months. Although it may be less cost-effective for the general population, there is still a substantial offset of initial procedure costs through lower rate of repeat revascularizations.
