  • ICF from an occupational therapy perspective in adult care : an integrative literature review
  • 2012
  • Ingår i: Scandinavian Journal of Occupational Therapy. - London, United Kingdom : Informa Healthcare. - 1103-8128 .- 1651-2014. ; 19:3, s. 260-273

    • Since its launch there has been increasing interest in the International Classification of Functioning, Disability and Health (ICF) within occupational therapy (OT). The aim of this study was to perform an integrative literature review, in order to present an overview of knowledge, where the ICF constitutes a significant part in relation to OT. A systematic literature search, covering the period 2001–2008, was performed in the databases MEDLINE, AMED, and CINAHL. A total of 112 articles were included and the majority had exploratory and descriptive designs. The results showed that ICF was valuable for research, clinical practice, and education. ICF was used to link existing instruments and to construct new outcome measures. Occupational therapists have been members of expert groups involved in the development of Core Sets for certain health conditions. Several positive aspects were described, e.g. an effective medium for communication at different levels. Many limitations were mentioned, such as unclear concepts and lack of subjective experiences. Suggestions for improvements were described. The conclusion was that the ICF has been used for a broad spectrum of purposes. The results indicated that further research is needed concerning application of the ICF in clinical practice and education.

  • Simulation Aided Design and Testing of Hydromechanical Transmissions
  • 2014
  • Ingår i: The 9th JFPS International Symposium on Fluid Power, Matsue, 2014. - 4931070108
  • Konferensbidrag (refereegranskat)abstract
    • This paper demonstrates the use of high-speed simulation in transmission conceptual design and presents a transmission test bed for hardware-in-the-loop simulations of hydromechanical transmission concepts. Complex transmissions, such as multiple-mode hydromechanical transmissions and hydraulic hybrid transmissions, present new difficulties and costs in the development process. There is today a greater demand for more efficient product development and more work has shifted towards simulation. The Hopsan simulation package allows robust, high-speed simulations suitable for both offline and hardware-in-the-loop simulation. New simulation models for hydromechanical transmissions are developed and used to simulate a known two-mode transmission concept. The same concept is also tested in hardware-in-the-loop simulations in the proposed transmission test bed. Results show good agreement with the hardware tests and highlight the proficiency of the simulation tools.

  • Amplitude analysis and branching fraction measurement of D-s(+)-> K- K+ pi(+) pi(0)
  • 2021
  • Ingår i: Physical Review D. - : American Physical Society. - 2470-0010 .- 2470-0029. ; 104:3
  • Tidskriftsartikel (refereegranskat)abstract
    • The first amplitude analysis of the decay D-s(+)-> K- K+ pi(+) pi(0) is presented using the data samples, corresponding to an integrated luminosity of 6.32 fb(-1), collected with the BESIII detector at e(+)e(-) center-of-mass energies between 4.178 and 4.226 GeV. More than 3000 events selected with a purity of 97.5% are used to perform the amplitude analysis, and nine components are found necessary to describe the data.

  • Ingår i: Journal of High Energy Physics (JHEP). - : Springer Nature. - 1126-6708 .- 1029-8479. ; :6
  • Tidskriftsartikel (refereegranskat)abstract
    • By using 6.32 fb(-1) of data collected with the BESIII detector at center-of-mass energies between 4.178 and 4.226 GeV, we perform an amplitude analysis of the decay D-s(+) -> K-S(0) pi(+)pi(0) and determine the relative fractions and phase differences of different intermediate processes, which include K-S(0) rho(770)(+), K-S(0)rho(1450)(+), K*(892)(0) pi(+), K* (892)(+) pi(0), and K* (1410)(0) pi(+). With the detection efficiency based on the amplitude analysis results, the absolute branching fraction is measured to be B(D-s(+) -> K-S(0) pi(+) pi(0)) = (5.43 +/- 0.30(stat) +/- 0.15(syst)) x 10(-3).

  • Amplitude analysis and branching-fraction measurement of D+s → K0SK−π+π
  • 2021
  • Ingår i: Physical Review D. - : American Physical Society. - 2470-0010 .- 2470-0029. ; 103:9
  • Tidskriftsartikel (refereegranskat)abstract
    • Using 6.32  fb−1 of e+e− collision data collected by the BESIII detector at the center-of-mass energies between 4.178 and 4.226 GeV, an amplitude analysis of the D+s → K0SK−π+π+ decays is performed for the first time to determine the intermediate-resonant contributions. The dominant component is the D+s → K∗(892)+¯K∗(892)0 decay with a fraction of (40.6±2.9stat±4.9sys)%. Our results of the amplitude analysis are used to obtain a more precise measurement of the branching fraction of the D+s → K0SK−π+π+ decay, which is determined to be (1.46±0.05stat±0.05sys)%.

  • Tidskriftsartikel (refereegranskat)abstract
    • Using e(+)e(-) annihilation data corresponding to a total integrated luminosity of 6.32 fb(-1) collected at the center-of-mass energies between 4.178 and 4.226 GeV with the BE- SIII detector, we perform an amplitude analysis of the decay D-s(+) -> K-K+pi(+)pi(+)pi(-) and de-termine the relative fractions and phases of different intermediate processes. Absolute branch- ing fraction of D-s(+) -> K-K+pi(+)pi(+)pi(-) decay is measured to be (6.60 +/- 0.47(stat). +/- 0.38(syst).) x 10(-3). The dominant intermediate process is D-s(+) -> a(1) (1260)(+)phi,phi -> K- K+, a(1)(1260)(+) -> rho pi(+), rho -> pi(+)pi(-), with a branching fraction of (5.15 +/- 0.41(stat.) +/- 0.32(syst.)) x 10(-3).

  • Amplitude analysis and branching-fraction measurement of D+s → π+π0η′
  • 2022
  • Ingår i: Journal of High Energy Physics (JHEP). - : Springer Nature. - 1126-6708 .- 1029-8479. ; :4
  • Tidskriftsartikel (refereegranskat)abstract
    • Using data collected with the BESIII detector in e(+)e(-) collisions at center-of-mass energies between 4.178 and 4.226 GeV and corresponding to 6.32 fb(-1) of integrated luminosity, we report the amplitude analysis and branching-fraction measurement of the D-s(+) -> pi(+)pi(0)eta' decay. We find that the dominant intermediate process is D-s(+) -> rho(+)eta' and the significances of other resonant and nonresonant processes are all less than 3 sigma. The upper limits on the branching fractions of S-wave and P-wave nonresonant components are set to 0.10% and 0.74% at the 90% confidence level, respectively. In addition, the branching fraction of the D-s(+) -> pi(+)pi(0)eta' decay is measured to be (6.15 +/- 0.25(stat.) +/- 0.18(syst.))%, which receives significant contribution only from D-s(+) -> rho(+)eta' according to the amplitude analysis.

  • Amplitude analysis and branching fraction measurement of Ds+ → K+K-π
  • 2021
  • Ingår i: Physical Review D. - : American Physical Society. - 2470-0010 .- 2470-0029. ; 104:1
  • Tidskriftsartikel (refereegranskat)abstract
    • We report an amplitude analysis and branching fraction measurement of D-s(+) -> K+K-pi(+) decay using a data sample of 3.19 fb(-1) recorded with BESIII detector at a center-of-mass energy of 4.178 GeV. We perform a model-independent partial wave analysis in the low K+K- mass region to determine the K+K- S-wave line shape, followed by an amplitude analysis of our very pure high-statistics sample. With the detection efficiency based on the amplitude analysis results, the absolute branching fraction is measured to be B(D-s(+) -> K+K-pi(+)) = (5.47 +/- 0.08(stat) +/- 0.13(sys))%.
