Dear SIAM members,
Did you know that SIAM offers discounted member rates for members of other mathematical societies? SIAM has a reciprocity agreement with 12 societies: view the entire list. If you would like to change your membership to a “reciprocal” category, contact SIAM Customer Service at firstname.lastname@example.org.
SIAM is pleased to announce the 2014 Class of SIAM Fellows. These distinguished members were nominated for their exemplary research as well as outstanding service to the community. Through their contributions, SIAM Fellows help advance the fields of applied mathematics and computational science.
SIAM would like to congratulate these 32 members of the community listed below in alphabetical order:
Mark Ainsworth, Brown University
John S. Baras, University of Maryland, College Park
Lorenz T. Biegler, Carnegie Mellon University
Åke Björck, Linköping University, Emeritus
Each year, the Society for Industrial and Applied Mathematics (SIAM) designates as Fellows of the society members who have made outstanding contributions to fields served by SIAM.
This year, SIAM is happy to recognize 32 members of the community for this honor. Fellows are nominated by peers for their distinguished contributions to the fields of applied mathematics and computational science and related disciplines.
The book, Mathematics and Climate, published by SIAM last October, has been honored by the Atmospheric Science Librarians International (ASLI) as the best book of 2013 in the fields of meteorology, climatology, and atmospheric sciences.
Mathematics and Climate is a timely textbook with wide appeal. It is aimed at students and researchers in mathematics and statistics who are interested in current issues of climate science, as well as at climate scientists who wish to become familiar with qualitative and quantitative methods of mathematics and statistics. The authors emphasize conceptual models that capture important aspects of Earth’s climate system and present the mathematical and statistical techniques that can be applied to their analysis. Topics from climate science include the Earth’s energy balance, temperature distribution, ocean circulation patterns such as El Niño–Southern Oscillation, ice caps and glaciation periods, the carbon cycle, and the biological pump. Among the mathematical and statistical techniques presented in the text are dynamical systems and bifurcation theory, Fourier analysis, conservation laws, regression analysis, and extreme value theory.

Improving radiation therapies for cancer mathematically
In a paper published in December in the SIAM Journal on Scientific Computing, authors Li-Tien Cheng, Bin Dong, Chunhua Men, Xun Jia, and Steve Jiang propose a method to optimize radiation therapy treatments in cancer patients.
Radiation therapy is one of the primary methods used for cancer treatment, along with chemotherapy and surgery. While doses of radiation are delivered to eliminate cancerous tissue, care is taken to keep radiation within acceptable levels so as not to affect neighboring tissues and organs. The most common type of therapy delivers high-energy radiation via a medical linear accelerator mounted on a rotating apparatus to adjust the direction, and a collimator to shape the beam of radiation. In the recently developed volumetric modulated arc therapy (VMAT), beams continuously deliver doses as the delivery device rotates around the patient. Enhancement of radiotherapy treatment is challenged by complexities of shape optimization, due to the mechanics of the equipment involved as well as the apertures of devices delivering the beams of radiation.

Philadelphia, PA—Vast amounts of data related to climate change are being compiled by research groups all over the world. Data from these many and varied sources results in diﬀerent climate projections; hence, the need arises to combine information across data sets to arrive at a consensus regarding future climate estimates.
In a paper published last December in the SIAM Journal on Uncertainty Quantification, authors Matthew Heaton, Tamara Greasby, and Stephan Sain propose a statistical hierarchical Bayesian model that consolidates climate change information from observation-based data sets and climate models.
“The vast array of climate data—from reconstructions of historic temperatures and modern observational temperature measurements to climate model projections of future climate—seems to agree that global temperatures are changing,” says author Matthew Heaton. “Where these data sources disagree, however, is by how much temperatures have changed and are expected to change in the future. Our research seeks to combine many different sources of climate data, in a statistically rigorous way, to determine a consensus on how much temperatures are changing.” Read the rest of this entry »

Dear SIAM members,
Here’s wishing you the very best in 2014! As we ring in the New Year, we welcome our new Board, Council and Activity Group officers. Read details on them below.
Though 2013 is past us, we don’t have to leave Mathematics of Planet Earth behind. The successful year-long initiative continues on. Please visit mpe2013.org for details on what to expect in 2014. Read the rest of this entry »
Equations help explain key parameters of stents that combat artherosclerosis
Philadelphia, PA—Coronary heart disease accounts for 18% of deaths in the United States every year. The disease results from a blockage of one or more arteries that supply blood to the heart muscle. This occurs as a result of a complex inflammatory condition called artherosclerosis, which leads to progressive buildup of fatty plaque near the surface of the arterial wall.
In a paper published last month in the SIAM Journal on Applied Mathematics, authors Sean McGinty, Sean McKee, Roger Wadsworth, and Christopher McCormick devise a mathematical model to improve currently-employed treatments of coronary heart disease (CHD).
“CHD remains the leading global cause of death, and mathematical modeling has a crucial role to play in the development of practical and effective treatments for this disease,” says lead author Sean McGinty. “The use of mathematics allows often highly complex biological processes and treatment responses to be simplified and written in terms of equations which describe the key parameters of the system. The solution of these equations invariably provides invaluable insight and understanding that will be crucial to the development of better treatments for patients in the future.” Read the rest of this entry »
From the Simons Foundation. Please read full announcement here.
The Simons Foundation’s Division for Mathematics and the Physical Sciences invites applications for grants to mathematicians to stimulate collaboration in the field primarily through the funding of travel and related expenditures.
The goal of the program is to support the ‘mathematical marketplace’ by substantially increasing collaborative contacts between mathematicians. The foundation will make a large number of grants to accomplished, active researchers in the United States who do not otherwise have access to funding for research that supports travel and visitors.
Applicants must have a tenure-track or tenured position, or be a professor emeritus, at a U.S. institution of higher education. They must have a current record of active research and publication in high-quality journals and not hold any other grants of over $3,000 per year that allow for support for travel or visitors during the Collaboration Grant award period.
Applicants may apply through proposalCENTRAL beginning September 1, 2013. The deadline to apply is January 31, 2014.
