Relativistic MHD Simulations of jets Abstract We have performed 3D RMHD simulations to investigate the stability and structure of highly relativistic MHD precessed jets with three different frequencies. As initial condition preexisting jet flow is established across the computational volume an input the precessional perturbation from the inner boundary. We show the results from simulations of a super-magnetosonic jet surrounded by a fast wind. The simulation results reveal complex pressure structure inside the RMHD jet. The structure will be produced by a combination of the helical surface and body modes excited by the precession. The jet strongly interacts with the external wind. It means significant energy loss from the jet surface. 1.Introduction 2.Simulation model 3.Results Our propose We investigate a detailed analysis of the time-dependent structures of relativistic jets by using 3D relativistic MHD simulations. Relativistic jets can exhibit time-dependent curved structures with superluminally moving component (3C345 etc.) or with both superluminally moving and more slowly moving or stational components (M87, 3C120 etc.). Superluminal motions along curved trajectories can be explained by helical jet model. Helical patterns are the expected result for Kelvin-Helmholtz and Current-driven jet instabilities in relativistic flows.

Control of nonlinear resonant photochemistry of 1,3-cyclohexadiene

Control of nonlinear resonant photochemistry of 1,3-cyclohexadiene

UV spectroscopy shows that more photoproduct was created by the tailored laser pulse than by the most intense pulse. The reaction is coherently driven by a laser pulse with negatively chirped phase (inset). Using a genetic algorithm and optical pulse shaper, we find ultrafast laser pulses that control the multi-photon ring-opening of cyclohexadiene (CHD). J. Chem. Phys., in press (2006).

Pavel B. Klimov Barry M. OConnor University of Michigan, Museum of Zoology, 1109 Geddes Ave., Ann Arbor, MI The next generation of identification tools: interactive programs incorporating multivariate models Context: The vast majority of interactive identification programs use a sequential approach to assign an unknown specimen to a known group. This algorithm works when the distinguishing characters do not have overlapping values. If the boundaries between taxa are overlapping, simultaneous (=probabilistic, matching) methods of identifications are more likely to lead to the correct assignment, but these methods usually require time-consuming measurements or experiments. We discuss how the sequential approach can be enhanced by multivariate statistics incorporated into this method. 1. INTRODUCTION Computer assisted interactive identification allows quick assignment of an unknown specimen to a known taxon with minimal costs in obtaining data and learning about the unknown. The number of characters used in the identification is substantially reduced compared to traditional taxonomic keys. For example, any of 128 taxa can be identified using only eight binary characters, or even fewer numeric or multistate characters. There are two major approaches to identification, sequential (=elimination, diagnostic) and simultaneous (=probabilistic, matching). In the sequential approach, only one character is used at each step of identification until the unknown specimen is assign...

(Bottom) Comparison of mean magnitudes and standard deviation; observed and simulated data have nearly identical characteristics. Figure 3: Time-series data can be folded with a period together with its simulated non-variable counterparts. Application of statistical indices to phase-folded data can reveal variability which were difficult to find from time-domain analysis alone.

INTRODUCTION: Large compilation of photometry data is expected in the era of virtual observatories. Variability indices and period determinations devised so far are not robust enough to allow fully automatic examination of time-series data. We are developing a new approach to detect variability from heterogeneous time series data. The underlying concept is to compare the observation data with a set of simulated ones and examine the presence of relative regularities in both time domain and phase domain. We test the robustness of our approach with samples of OGLE-II and SkyDOT databa... -image captions -arrows pointing to Balmer filaments -lower loop or zoomed Balmer filament image? -references?

Fostering Interest in Information Technology htt://fit.umd.umich.edu Mesut Duran University of Michigan-Dearborn Abstract project is designed to provide opportunities for underrepresented and underserved high-school students, particularly those from disadvantaged urban communities in the Southeastern Michigan to learn about, experience, and use IT within the context of science, technology, engineering, and mathematics (STEM). The project will accomplish its goal through the creation of a “Community of Designers”—an environment where high-school students, K-12 STEM teachers, undergraduate/graduate student assistants (U/GSAs), and post-secondary STEM content experts work together. The project will establish and facilitate four project-based design teams, each focusing on an IT-intensive STEM area. Each design team will consist of 10 high-school students, one school teacher, one U/GSA, and one post-secondary STEM content area expert. The overarching task of each design team is to learn about, experience, and use IT within the context of STEM and explore 21st century career and educational pathways. Each design team's members will participate in several year-round, two-year IT enrichment experiences and opportunities. The project calls for the investment and robust participation of students and parents, area school districts, the University of Michigan-Dearborn (UM-D)'s colleges and schools, and the region’s busine...
