## Office of Naval Research to Host S&T Conference in October

The Office of Naval Research (ONR) will host its biennial Naval Science and Technology (S&T) Partnership Conference October 22-24 in Arlington, Virginia. Similar to events hosted by ONR’s Army and Air Force counterparts, the conference provides researchers interested in ONR with the opportunity to hear from agency leadership about current priorities and to learn about how specific research ideas may align with them. As Lewis-Burke Associates LLC has previously reported, the significant autonomy enjoyed by DOD program managers in making funding decisions enhances the importance of building personal relationships and raising profile by attending events like the S&T Conference. Anticipated speakers at the event include Secretary of the Navy Ray Mabus, Chief of Naval Research Matthew Klunder, Marine Corps Commandant James Amos, and other senior Navy officials. ONR program managers will also attend the event, which provides an excellent networking opportunity for interested researchers to engage with staff on future ONR research objectives.

Additional information on the Conference, including a complete agenda and registration information, is available on the ONR website here.

## Travel Grants for MCA 2013

The American Mathematical Society (AMS) has received funds from the National Science Foundation (NSF) to provide partial travel support for up to sixty U.S. mathematicians attending the inaugural meeting of the Mathematical Congress of the Americas (MCA) to be held August 5-9, 2013 in Guanajuato, Mexico.

Instructions on how to apply for support are available on the AMS website here. The application period will be **September 15-October 31, 2012.** This travel grants program will be administered by the Membership and Programs Department of the AMS.

The program is open to U.S. mathematicians (who must be affiliated with a U.S. institution at the time of travel). It is expected that the program will provide travel support for both U.S.-based invited speakers (senior mathematicians) and early career mathematicians. Early career mathematicians (those within six years of their doctorate), women, and members of U.S. groups underrepresented in mathematics are especially encouraged to apply. Invited speakers from U.S. institutions to MCA 2013 should submit applications, if funding is desired.

Applications will be evaluated by a panel of mathematical scientists under the terms of a proposal submitted to the NSF by the AMS.

Mathematicians accepting grants for partial support of travel to MCA 2013 may not supplement them with any other NSF funds. Currently, it is the intention of the NSF’s Division of Mathematical Sciences to provide no additional funds on its other regular research grants for travel to MCA in 2013. However, an individual mathematician who does not receive a travel grant may use regular NSF grant funds, subject to the usual restrictions and prior approval requirements.

All information currently available about the MCA 2013 program, organization and registration procedure is located on the Congress website.

For questions or more information, contact Steven Ferrucci at sxf@ams.org, 800-321-4267, ext. 4113 or 401-455-4113.

SIAM is a sponsor of MCA 2013.

## DMS Name Change. Or Not.

The mathematical sciences community was embroiled in discussions since the fall of 2011 about whether the name of the Division of Mathematical Sciences (DMS) should be changed to include statistics in the title. Societies, including SIAM, became involved in the discussions through the advisory committee for math and physical sciences (MPS Advisory Committee) at NSF. SIAM, along with its sister societies, sought opinions from the community and provided the MPS AC with the commentary we received.

In his letter to the advisory committee, Associate Director for MPS Ed Seidel states that he has decided to retain the DMS name, but will take other steps to recognize the important role of statistics in the mathematical sciences. In particular, Seidel states that say “whenever appropriate, we will specifically mention ‘statistics’ alongside ‘mathematics’ in budget requests and in solicitations in order to recognize the unique and pervasive role of statistical sciences….”

Documentation on the charge to the advisory committee on this issue, along with a summary of responses, and Seidel’s letter announcing his decision may be found here.

## SIAM John von Neumann Lecture awarded to John Ball

The Society for Industrial and Applied Mathematics (SIAM) awarded the 2012 John von Neumann Lecture to Sir John Ball of the University of Oxford in recognition of his deep contributions to our understanding of the mechanics of materials via the calculus of variations and other branches of mathematical analysis.

The citation especially notes his pioneering work on existence theorems and constitutive models for nonlinear elasticity, cavitation in solids, irregular minimizers and material microstructure, and, more recently, defects in liquid crystals.

The John von Neumann Lecture is awarded each year by SIAM to a mathematician or scientist for outstanding contributions to the field of applied mathematical sciences and their effective communication to the community. Established in 1959, SIAM’s flagship lecture is given in honor of the Hungarian-American mathematician after whom it is named, and whose pioneering research encompassed the fields of mathematics, physics, economics, computer science, and statistics.

Professor Ball accepted the prestigious award from SIAM President Nick Trefethen at the Prizes and Awards Luncheon, following which, he delivered The John von Neumann Lecture, Liquid Crystals for Mathematicians, on Tuesday, July 10, at the SIAM Annual Meeting in Minneapolis, Minnesota.

An important and versatile interface for electronic visual displays in a wide range of equipment from calculators to television screens, liquid crystals are the working substance behind a multi-billion dollar industry. Representing a class of soft matter systems that exhibit properties intermediate to solid crystals and isotropic fluids, they present an intriguing subject for mathematical analysis. In a very engaging lecture, Dr. Ball described various branches of mathematics, including partial differential equations, the calculus of variations, multiscale analysis, scientific computation, dynamical systems, algebra and topology, that can explain the math behind liquid crystals.

## Barbara Keyfitz receives awards for research and service in applied mathematics

The Society for Industrial and Applied Mathematics (SIAM) awards the SIAM Prize for Distinguished Service to the Profession to an applied mathematician who has made noteworthy contributions to the furtherance of applied mathematics on the national level. The 2012 award goes to Barbara Lee Keyfitz of The Ohio State University.

Professor Keyfitz is a fitting recipient of the prize, as evidenced by her long-term and pervasive advocacy of applied mathematics in a career spanning several leadership roles. As the Director of the Fields Institute in Toronto (2004-2008), Keyfitz revitalized applied mathematics programming with initiatives such as the successful Fields-MITACS Industrial Problem-Solving workshops. An innovative graduate industrial research internship program was created for students all over Canada during her term on the Board of Directors of MITACS-NCE (Network of Centres of Excellence), a program that has since expanded to cover all disciplines. Closer links between SIAM’s US and Mexican communities are owed in part to Keyfitz’s efforts in organizing numerous SIAM-SMM (Mexican Mathematical Society) conferences. She has served as President of the Association for Women in Mathematics (2005-2006), as SIAM Vice President for Programs (1998-2003), and is currently the President of ICIAM.

If her contributions to the field need any reinforcing, Professor Keyfitz also received this year’s AWM-SIAM Sonia Kovalevsky Lecture for her pioneering and seminal contributions to the field of hyperbolic conservation laws. In collaboration with Herbert Kranzer, she introduced the novel and important notion of singular shocks and made the original study of their properties. Her research group also spearheaded the revival of the rigorous treatment of transonic gas flow, now a very active research area. Important applications of her work include aerodynamics and multiphase flow models in porous media. The AWM-SIAM Sonia Kovalevsky Lecture is awarded annually at the SIAM Annual Meeting to highlight significant contributions of women to applied or computational mathematics.

The Dr. Charles Saltzer Professor of Mathematics at the Ohio State University, Dr. Keyfitz was recognized for her contributions at the SIAM Annual Meeting held in Minneapolis, Minnesota from July 9-13. Dr. Keyfitz delivered the AWM-SIAM Sonia Kovalevsky Lecture, *The Role of Characteristics in Conservation Laws*, on Monday afternoon and accepted her awards the following day at the Prizes and Awards Luncheon.
