The purpose of this study was to examine the effect of sampling epoch on total time spent walking and number of walking bouts per day in persons with stroke. Ninety-eight persons with average age of 63.8 yr and average time poststroke of 43.6 mo participated. Participants wore a StepWatch Activity Monitor for 3 to 5 consecutive days. The number of strides taken was collected in consecutive 5 s ...

Context. There is observed a trend that a lower mass galaxy forms stars at a later epoch. This downsizing of star-forming galaxies has been attributed to hydrodynamical or radiative feedback processes that regulate star formation. Aims. We explain the downsizing by gravitational processes alone, in the bottom-up scenario where galaxies evolve from subgalactic-scale objects. Methods. Using the t...

Previous work investigating the role of MDR-1 overexpression in relapsed and refractory lymphoma led us to investigate a possible role for multidrug resistance-associated protein (MRP) as a cause of resistance in patients who did not overexpress MDR-1. A quantitative polymerase chain reaction (PCR) method for measuring MRP expression was validated. Immunoblot analysis suggested that no major di...

A summary of the photometric data obtained by the Hipparcos and Tycho missions is presented. The photometric signals and their reduction to magnitudes are described, as well as the passbands and their evolution. The main mission photometry provided on average 110 observations for each of the 118 000 stars observed during the mission. The accuracies for this epoch photometry range from a few mil...

A scrutiny of the existing time differencing carrier phase (TDCP) velocity estimation algorithms has revealed several shortcomings which could be further improved. One of those is that the velocity estimation at epoch t would require the receiver positions at epoch t+Δt or more are available. Another one is the usage of satellite velocities in the calculations which would increase the receiver ...

Abstract The episode of widespread organic carbon deposition marked by peak black shale sedimentation during the Palaeoproterozoic is also reflected in exceptionally abundant graphite deposits this age. Worldwide anoxic/euxinic sediments were preserved as a deep crustal reservoir both carbon, and sulphur accompanying pyrite, commonly >1 wt %. carbon- sulphur-rich crust interacted with mafic ...

A general theory of epoch extraction of overlapping nonidentical waveforms is presented. The theory is applied to outputs of models of voiced speech production mechanism and to actual speech data. Some typical glottal waveshapes are considered to explain their effect on the speech output. It is shown that the points of excitation of the vocal tract can be precisely identified for continuous spe...

I present a biased review of when the epoch of formation of galaxies (both disks and ellipticals) maybe took place. I base my arguments in simple (mostly) analytic models that have been recently developed to reproduce most of the observed photometric, chemical and dynamical properties of galaxies both at low and high redshift.
