Dynamics Of The Dbi Spike Soliton, David Kastor, Jennie Traschen Dec 1999

Dynamics Of The Dbi Spike Soliton, David Kastor, Jennie Traschen

David Kastor

We compare oscillations of a fundamental string ending on a D3-brane in two different settings: (1) a test-string radially threading the horizon of an extremal black D3-brane and (2) the spike soliton of the DBI effective action for a D3-brane. Previous work has shown that overall transverse modes of the test-string appear as l=0 modes of the transverse scalar fields of the DBI system. We identify DBI world-volume degrees of freedom that have dynamics matching those of the test-string relative transverse modes. We show that there is a map, resembling T-duality, between relative and overall transverse modes for the test-string …


Reduction Of Fe(Iii), Mn(Iv), And Toxic Metal At 100 Degrees C By Pyrobaculum Islandicum, Kazem Kashefi, Derek Lovley Dec 1999

Reduction Of Fe(Iii), Mn(Iv), And Toxic Metal At 100 Degrees C By Pyrobaculum Islandicum, Kazem Kashefi, Derek Lovley

Derek Lovley

It has recently been noted that a diversity of hyperthermophilic microorganisms have the ability to reduce Fe(III) with hydrogen as the electron donor, but the reduction of Fe(III) or other metals by these organisms has not been previously examined in detail. When Pyrobaculum islandicum was grown at 100 degrees C in a medium with hydrogen as the electron donor and Fe(III)-citrate as the electron acceptor, the increase in cell numbers of P. islandicum per mole of Fe(III) reduced was found to be ca. 10-fold higher than previously reported. Poorly crystalline Fe(III) oxide could also serve as the electron acceptor for …

Climate Variability In The Andes Of Ecuador And Its Relation To Tropical Pacific And Atlantic Sea Surface Temperature Anomalies, Mathias Vuille, Raymond S. Bradley, Frank Keimig Oct 1999

Climate Variability In The Andes Of Ecuador And Its Relation To Tropical Pacific And Atlantic Sea Surface Temperature Anomalies, Mathias Vuille, Raymond S. Bradley, Frank Keimig

Raymond S Bradley

The main spatiotemporal modes of seasonal precipitation and temperature variability in the Andes of Ecuador (1N–4S) and their relation to tropical Pacific and Atlantic sea surface temperature anomalies (SSTAs) between 1963–92 are identified based on rotated principal component analysis and cross-correlation techniques. Outgoing longwave radiation composites are analyzed during periods of strong oceanic forcing to confirm the proposed physical mechanisms. Despite the close proximity to the Pacific, precipitation variability in the Andes of Ecuador is not related to SSTA in the tropical Pacific domain alone. The El Nin˜o–Southern Oscillation influence is most dominant in the northwestern part of the Andes …
