Nonlinear Analysis B: in press, 2004. The Swift-Hohenberg fluid convection system with both local and nonlocal nonlinearities under the influence of white noise is studied. The objective is to understand the difference in the dynamical behavior in both local and nonlocal cases. It is proved that when sufficiently many of its Fourier modes are forced, the system has a unique invariant measure, o...

The Oxford SWIFT spectrograph, an I & z band (6500–10500 Å) integral field spectrograph, is designed to operate as a facility instrument at the 200 inch Hale Telescope on Palomar Mountain, in conjunction with the Palomar laser guide star adaptive optics system PALAO (and its upgrade to PALM3000). SWIFT provides spectra at R( / )~4000 of a contiguous two-dimensional field, 44 89 spatial pixels (...

Little is known of the life-history of many parasitic species. This hinders a full understanding of host-parasitic interactions. The common swift louse fly, Crataerina pallida Latreille (Diptera: Hippoboscidae), an obligate haematophagous parasite of the Common Swift, Apus apus Linnaeus 1758, is one such species. No detrimental effect of its parasitism upon the host has been found. This may be ...

On 5 July 2001, SWIFT and FIX Protocol Limited (FPL) announced that the two organisations will seek convergence of their respective messaging protocols by centering on the development and adoption of ISO 15022 XML as a common industry standard. SWIFT and FPL will actively support the efforts of ISO Working Group 10, the group focused on the migration to XML of ISO 15022, which is the current st...

With the rapid technological advances in high-performance computing, access to parallel computing resources is becoming more prevalent in the scientific community. Scientific computation has been proven to be an invaluable tool for tackling challenges faced by science, but writing massivelyparallel software for scientific applications remains difficult and requires years of training and practic...

What factors affect client perception of vendor preference in a crowdsourcing marketplace? We approach this question from two theoretical perspectives in this study. First, extending the knowledge of e-commerce transaction, we propose the concept of vendor-task fit in this study and test its relationship to vendor preference. Second, we posit that swift trust also influences client decisions. O...

We show that Gamma Ray Bursts (GRBs) of known redshift and rest frame optical extinction detected by the Swift satellite fully confirm earlier results concerning the distribution of the optical afterglow luminosity at 12 hours after trigger (rest frame time). This distribution is bimodal and relatively narrow, especially for the high luminosity branch. This is intriguing, given that Swift GRBs ...

The Swift-Hohenberg equation is a central nonlinear model in modern physics. Originally derived to describe the onset and evolution of roll patterns in Rayleigh-Bénard convection, it has also been applied to study a variety of complex fluids and biological materials, including neural tissues. The Swift-Hohenberg equation may be derived from a Lyapunov functional using a variational argument. He...

A good fraction of GRBs detected by Swift are at a large redshift (up to z = 6.3, so far). Their study allows us to investigate, among other things, the cosmic star formation in the early Universe (possibly up to the re-ionization era) and the chemical enrichment of the high-redshift gas. Here we present and discuss a method of selection which identifies high-redshift candidates based only upon...

Mathematical models have become an important tool for understanding the control of eye movements during reading. Main goals of the development of the SWIFT model (R. Engbert, A. Longtin, & R. Kliegl, 2002) were to investigate the possibility of spatially distributed processing and to implement a general mechanism for all types of eye movements observed in reading experiments. The authors presen...
