Recent advances in stroke outcomes research: contributions from Canada.
Stroke is a devastating disease for patients, families and the healthcare system. Outcomes research can contribute with the analysis, evaluation and dissemination of the result of specific treatment, processes of care or medical procedures to improve patient outcomes. According to the Agency for Healthcare Research and Quality (2000), outcomes research "seeks to understand the end results of sp...
متن کاملRare Kaon
Recent experiments on rare kaon decays are described, with emphasis on the program at the Brookhaven National Laboratory Alternating Gradient Synchrotron. New limits on the modes KL + pe and Kr, -v ee and a preliminary new measurement of the Kr. + pp branching ratio are presented from AGS Experiment 791. Other modes, including K+ + x+p’+e-, K+ + r+ + nothing, and KL -+ r’e+e-, which have been t...
متن کاملKaon Physics
The most recent progress and future prospects in kaon physics are reviewed. Main results are the first observation of the rare decays KS → π ee and KS → π μμ by NA48, newK → πνν event observed by E949 and new precision measurements of KS,L → πeν decays by KTeV, KLOE and NA48 made in an effort to resolve the slight deviation from the unitarity in the CKM matrix, involving the |Vus| coupling.
متن کاملKaon-Nucleus Drell-Yan Processes and Kaon Structure Functions
We investigate the information which could be obtained from Drell-Yan processes with sufficiently intense beams of charged kaons on isoscalar targets. It is found that combinations of K and K− Drell-Yan measurements on isoscalar nuclear targets would allow one to extract the kaon sea quark distributions. These cross sections are also sensitive to the strange valence quark distribution in the ka...
متن کاملCovariant kaon dynamics and kaon flow in heavy ion collisions
The influence of the chiral mean field on the K transverse flow in heavy ion collisions at SIS energy is investigated within covariant kaon dynamics. For the kaon mesons inside the nuclear medium a quasi-particle picture including scalar and vector fields is adopted and compared to the standard treatment with a static potential. It is confirmed that a Lorentz force from spatial component of the...
