Engaging in Engineering Initiative with Centennial Place Academy

Yanzhi Xu Alice Grossman Atiyya Shaw Parbha Pratyaksa Aaron Greenwood

Transportation engineering researchers at the Georgia Institute of Technology developed an active learning outreach program for Centennial Place Academy, a metro Atlanta public school that serves a racially and economically diverse student population with the majority of students falling into lower income brackets and minority populations. Georgia Tech researchers visited the school to conduct an initial session with the entire fifth grade class; this was followed by two full day sessions with a smaller subset of the same students after they had moved into the sixth grade. The program was designed to utilize cutting-edge technology to implement Science, Technology, Engineering, and Mathematics (STEM) education with elementary and middle school students through guided inquiry. The purpose of the program was to show students that engineering is an accessible discipline that utilizes many skillsets and encompasses multiple aspects of their lives. The program resulted in a wealth of ready-to-use materials that can be implemented in future engineering outreach initiatives.

Mode identification from spectroscopy of gravity-mode pulsators

Proceedings of the International Astronomical Union (2013)

K. R. Pollard E. Brunsden P. L. Cottrell M. W. Davie Aaron Greenwood

Abstract The gravity modes present in γ Doradus stars probe the deep stellar interiors and are thus of particular interest in asteroseismology. For the MUSICIAN programme at the University of Canterbury, we obtain extensive high-resolution echelle spectra of γ Dor stars from the Mt John University Observatory in New Zealand. We analyze these to obtain the pulsational frequencies and identify these with the multiple pulsational modes excited in the star. A summary of recent results from our spectroscopic mode-identification programme is given.

Spectroscopic mode identification of γ Doradus stars: frequencies, modes, rotation and wave leakage

Proceedings of the International Astronomical Union (2015)

K. R. Pollard E. Brunsden M. W. Davie Aaron Greenwood P. L. Cottrell

Abstract The gravity modes present in γ Doradus stars probe the deep stellar interiors and are thus of particular interest in asteroseismology. The MUSICIAN programme at the University of Canterbury has been successfully identifying frequencies and pulsation modes in many γ Doradus stars using hundreds of precise, high resolution spectroscopic observations obtained with the 1.0 m telescope and HERCULES spectrograph at the Mt John Observatory in New Zealand. In this paper we present a summary of our spectroscopic frequency and mode identifications. Of particular interest from our spectroscopic analyses are: the prevalence of (ℓ, m ) = 1, 1 modes in many γ Dor stars; the importance of stellar rotation in the interpretation of the frequency and mode identification; and finally, possible evidence of wave leakage in one of these stars.

Crystal structure of an idiotype-anti-idiotype Fabcomplex.

Proceedings of the National Academy of Sciences (1994)

Nenad Ban Carlos Escobar R. Garcia Karl W. Hasel John Day

Anti-idiotypic monoclonal antibody 409.5.3 is raised against an antibody that neutralizes feline infectious peritonitis virus. This antibody, used as an immunogen, elicits the production of anti-anti-idiotypic antibodies that in turn neutralize the virus. The crystal structure of the complex between anti-idiotypic Fab 409.5.3 and idiotypic Fab fragment of virus-neutralizing antibody has been solved by molecular replacement using real-space Patterson search and filtering by Patterson correlation-coefficient refinement. The structure has been refined to an R value of 0.21 based on 21,310 unique reflections between 40.0 and 2.9 A. The three-dimensional structure reveals extensive, specific interactions that involve 118 van der Waals contacts and at least 9 probable hydrogen bonds. The two Fabs are rotated 61 degrees with respect to each other around the approximate long axis of the complex and are within 26 degrees being aligned along their major axes.
