Geological records on earth are largely set in stone, or at least the distinctive fossils to be found in different layers of rock. The geological time scale also tends to span millions of years though more recently they have comprised mere millennia, with the most recent epoch, the Holocene, traced back to have begun just 11,700 years ago at the end of the last ice age. But geologists are now c...

We have modelled the process of reionization of the intergalactic medium (IGM) by photoionization by galaxies, in order to learn what galaxy formation in the framework of the CDM model predicts for the epoch of reionization. We use a sophisticated semi-analytic model of galaxy formation to track the formation of these galaxies, their influence on the IGM, and the back-reaction of the state of t...

Book Review cerebellum. The distilled message of these five well-The Cerebellar Epoch presented chapters is two new proposed nomenclature systems. The first is a so-called quadrapartite lobular Development of the Cerebellar System in Relation to division of the cerebellum into an anterior lobe (vermal The authors justify this view based on others' physiological studies and on their own embryolo...

(b). Substructure generation in the 3-D nite element mesh shown in Fig. 4 using Competitive learning. tures for domain decomposition using ANN paradigms. This study demonstrates the usefulness of neural networks for solving large optimization problems with reasonable speed, that are nontrivial, but may not be as hard as for example, the traveling salesman problem. Both techniques yield signican...

We have obtained a second epoch of Hubble Space Telescope NICMOS observations of seven Young Stellar Objects: HH 30, L1551 IRS5, IRAS 04016+2610, IRAS 04302+2247, Haro 6-5B, CoKu Tau/1 and DG Tau B. The first epoch observations were taken in 1997 as part of two different programs, while the second epoch were obtained in 2004 as part program to measure polarization in these objects. Data obtaine...
