WHEN certain typical plants, such as Cosmos (Cosmos bipinnatus), Salvia (Salvia splendens) and soybeans (Soja max) are exposed to a short photoperiod (7to 8-hour day) and a relatively long one (14to 15-hour day) they exhibit conspicuous differences in rate of growth, time of sexual reproduction and greenness of foliage. The short-day soybean plants, for instance, are lighter in color early in t...

We present constraints on the amplitude and shape of the matter power spectrum and the density of dark matter within the framework of a standard ΛCDM model. We use a Markov chain Monte Carlo approach to combine independent measurements of the three-dimensional weak gravitational lensing shear field by the COSMOS survey, of lowand high-resolution Lyman-α (Lyα) forest flux power spectrum by SDSS ...

We present the results of a search for galaxy clusters in the first 36 XMM-Newton pointings on the COSMOS field. We reach a depth for a total cluster flux in the 0.5–2 keV band of 3× 10 ergs cm s, having one of the widest XMM-Newton contiguous raster surveys, covering an area of 2.1 square degrees. Cluster candidates are identified through a wavelet detection of extended X-ray emission. Verific...

What is the relationship between external—physical and biological—influences on increasingly complex matter over billions of years? In his most recent book, Islands in the Cosmos: the Evolution of Life on Land, Dale Russell attempts to answer this question. Russell is the senior curator of paleontology at the North Carolina Museum of Natural Sciences and, among other things, is well known for p...

On the base of the chosen models, the comparison of simulation and optimization possibilities for languages DYNAMO and COSMIC & COSMOS, is presented. The computational techniques, for example: integration facilities, optimization opportunities, are the main point of interest for this comparison.

A quantum field theory warm inflation model is presented that solves the cosmological horizon/flatness problems. An interpretation of the model is given from supersymmetry and superstring theory. To appear in Proceedings COSMOS 98, Monterey, CA, November 1998
