Clusters at Half Hubble Time: Galaxy Structure and Colors

We study the photometric and structural properties of spectroscopically confirmed members in the two massive X-ray–selected z 0:83 galaxy clustersMS 1054–03 and RX J0152.7 1357 using three-band mosaic imaging with the Hubble Space Telescope Advanced Camera for Surveys. The samples include 105 and 140 members of RX J0152.7 1357 and MS 1054–03, respectively, to i775 < 24:0. A quantitative classif...

Atrioventricular Pressure Half-Time

was less than 25 msec. Although exercise increased the atrioventricular pressure gradient, heart rate, and cardiac output significantly, the half-time was affected only slightly. Mitral regurgitation of various severities did not affect the half-time. The half-time appears to vary inversely with the anatomic orifice area of the mitral valve. The determination of the half-time obviates the need ...

Cognitive semio-linguistics studies the relations between signs and language, between semiological and linguistic structures, as expressions of, and as causes of, the cognitive activities involved in thinking, here called epistemic activities. This short essay displays a leveled analysis of the relations holding between semio-linguistic and epistemic structures active in the human mind. 1. Semi...
