[Aspuru-Guzik group list] special group meeting tomorrow for Excitonics and QUBE

by Ryan Babbush

Hi Everyone, This is a reminder that tomorrow afternoon at 3-5pm there is a special group meeting that should be considered mandatory for people related to the QUBE projects with Seth Lloyd and Jianshu Cao. The meeting is in the QI Common Room, Room 26-201 at MIT. There is also information about it on the calendar. Please note, this is not a general group meeting and we will still have group meeting this Friday at 2pm. -- Ryan Babbush | PhD Student in Chemistry (949) 331-3943 | babbush(a)fas.harvard.edu Harvard University | Aspuru-Guzik Research Group 12 Oxford Street, Box 400 | Cambridge, MA 02138

[Aspuru-Guzik group list] Cheminformatics, data-mining, and finding correlation between variables in large data sets

by Laszlo Seress

Hi Everyone, My friend just sent me a paper regarding a tactic for data-mining large dimensional data sets and finding correlations between variables (kind of what we're trying to do with the cheminformatics). The link to the paper is here: http://www.sciencemag.org/content/334/6062/1518 Abstract: Identifying interesting relationships between pairs of variables in large data sets is increasingly important. Here, we present a measure of dependence for two-variable relationships: the maximal information coefficient (MIC). MIC captures a wide range of associations both functional and not, and for functional relationships provides a score that roughly equals the coefficient of determination (*R*2) of the data relative to the regression function. MIC belongs to a larger class of maximal information-based nonparametric exploration (MINE) statistics for identifying and classifying relationships. We apply MIC and MINE to data sets in global health, gene expression, major-league baseball, and the human gut microbiota and identify known and novel relationships. I'm not sure if it's exactly what we need, but I thought I'd pass it along. Best, Laszlo P.S. cc-d Aspuru-Group in case anyone else is interested. -- Laszlo Ryan Seress

This seminar originally was developed two years ago by a committee led by Professor Eric Mazur of the School of Engineering and Applied Sciences. While in the past we have limited the pilot presentations to PRISE fellows, this year’s seminar, taught by Director of Physical Sciences Education Logan McCarty, is open to all undergraduates who are in the Boston/Cambridge area conducting research this summer. The interactive approach focuses on three interesting case studies to help students identify and consider fundamental matters of responsible conduct in research. As you may know, the National Science Foundation is now requiring institutional certification in proposal submissions articulating a plan for guidance and training of undergraduates, graduate students, and postdoctoral fellows on research integrity. The seminar is offered in part to fulfill this obligation to the NSF as an institutional benchmark of awareness at the undergraduate level. I would appreciate it if you could spread the word among faculty in your department and/or research unit that this training is available and encourage their undergraduate researchers to attend. Students who are interested in attending the seminar may RSVP at * undergradresearch(a)fas.harvard.edu* <undergradresearch(a)fas.harvard.edu>, or simply show up (after which they will be asked to sign in at the end of the session). My office will keep record of all Harvard undergraduates who have participated in the seminar. Please let me know if you have any questions, and thanks for your help promoting this opportunity to our undergraduates conducting research. With all best wishes, Yours truly—Greg Llacer. *Gregory A.

[Aspuru-Guzik group list] Fwd: Summer School "Efficient Algorithms in Computational Physics"

by sarah mostame

Dear colleague, we would like to draw your attention to our DPG-School on Physics Efficient Algorithms in Computational Physics Physics Center Bad Honnef, Germany, 10. - 14. September 2012 http://www.dpg-physik.de/dpg/pbh/aktuelles/S112.html?lang=en& Computer simulations play an ever increasing role in physics research. This school will provide an introduction to the field, including up-to-date research topics. A particular emphasis of this school will be efficient algorithms, which allow one to study larger system sizes than with standard approaches. Since doing computer simulations means learning by doing, the school comprises, in addition to lectures, of a considerable amount of HANDS-ON EXERCISES at the computer, which makes this school rather special in its field. The school addresses students which have a physics background and basic knowledge in a higher programming language. like Pascal, C/C++, or Fortran. The language used throughout the school will be the C programming language (and some Python scripts). The school is highly subsidized by the German Physical Society (DPG), which result in small fees, e.g., for students who are DPG members only 215 Euros for full boarding and including lodging. There is no registration deadline, but we have a limited number of places. The registration is FIRST-COME-FIRST-SERVED. The school is organized by Alexander K. Hartmann (Oldenburg) and A. Peter Young (Santa Cruz). Other Lecturers: Anthonius Coolen, King's College, London, UK Helmut G. Katzgraber, Texas A&M University, College Station, USA Werner Krauth, Ecole Normale Superieure Paris, France Frauke Liers, University of Cologne, Germany Roger G. Melko, University of Waterloo, Canada Heiko Rieger, University of Saarbruecken, Germany Robert M. Ziff, University of Michigan, Ann Abor, USA More information, poster, application form, etc, see http://www.dpg-physik.de/dpg/pbh/aktuelles/S112.html?lang=en& Please forward this announcement to people who might be interested in the school. Thank you very much. Best regards Alexander Hartmann and Peter Young ------------------------------------------------------ Prof. Dr. Alexander K.

[Aspuru-Guzik group list] [Aspuru-meetings-list] AMP Seminar Friday, June 15, Yi Liu (Inst. of Atmospheric Physics Chinese Academy of Sciences) The Chinese carbon dioxide observation satellite (TanSat) project

by James F. Babb

Please join us for an informal seminar sponsored by the Atomic and Molecular Physics Division, Harvard-Smithsonian Center for Astrophysics. (Complete schedule at http://www.cfa.harvard.edu/amp/events.html) 11:00 AM Friday, June 15, 2012 Phillips Auditorium 60 Garden St, Cambridge, MA The Chinese carbon dioxide observation satellite (TanSat) project Yi Liu (Key Laboratory of Middle Atmosphere and Global Environmental Observation, Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing) The Chinese carbon dioxide observation satellite (TanSat) project is one of the national high technology research and development programs. It is funded by the ministry of science and technology of the People¢s Republic of China and the Chinese Academy of Sciences. The TanSat will be launched in 2015 to monitor the carbon dioxide in Sun-Synchronous orbit. Two instruments will be onboard the TanSat. The main instrument is a high resolution grating spectrometer that measures reflected sunlight with the 0.76 micron O2 A-band and two CO2 bands at 1.61 and 2.06 micron. The second instrument is the Cloud and Aerosol polarization Imager (CAPI). It is a wide field of view moderate resolution imaging spectrometer, and it includes 0.38, 0.67, 0.87, 1.375 and 1.64 micron channels, with polarization channels at 0.67 micron and 1.64 micron. Soundings recorded from main instrument will be used to retrieve the column-averaged CO2 dry air mole fraction (XCO2), while data from CAPI will be used to correct for cloud and aerosol interferences. A full physical optimal estimation method is being developed as a retrieval method of XCO2, while other sensitive parameters will be inversed at the same time. A ground based observation network will be established around China to validate satellite observation of CO2, aerosol and cloud. The CO2 observation consists of 3 Bruker IFS125 and 3 Optical Spectrum Analyzers, and the aerosol observation is achieved by 10 CE-318 sunphotometers. The object of TanSat is to monitor XCO2 from space with precision of 1~4 ppmv. Global and regional CO2 sources and sinks will be derived from XCO2 observations based on a data assimilation system. _______________________________________________ Aspuru-meetings-list mailing list Aspuru-meetings-list(a)lists.fas.harvard.edu https://lists.fas.harvard.edu/mailman/listinfo/aspuru-meetings-list
