Weak lensing observations and supernova observations, combined with CMB observations, can both provide powerful constraints on dark energy properties. Considering statistical errors only, we find luminosity distances inferred from 2000 supernovae and large-scale (l < 1000) angular power spectra inferred from redshift-binned cosmic shear maps place complementary constraints on w 0 and w a where ...

introduction: peripheral vascular disease (pvd) is a major cause of morbidity and is associated with coronary artery disease (cad). we aimed to perform lower limb perfusion scan (llps) in patients referred for myocardial perfusion imaging (mpi) and estimate prevalence of pvd in subgroups with normal and abnormal mpi results. we also compared quantitative indices of llps in patients with and wit...

Our previous investigations on the returning behavior of rats (Eukaszewska 1963, 1966ab) suggested that frontal rats are more dependent on visual stimuli than normal subjects. This suggestion was derived from the following findings: (i) frontal Ss performed on a lower level than normal Ss, (ii) the performance of frontal Ss improved considerably lafter blinding, and (iii) the performance of nor...
