The Society for Industrial and Applied Mathematics, (SIAM) was formed in 1951 in Philadelphia, Pennsylvania. Since its inception, SIAM has grown to over 12,000 members with sections in the U.K., East Asia, Bulgaria, Ireland and Argentina. The primary purpose of SIAM is the industrial application of mathematics. The motto is “Science and Industry Advance with Mathematics.” Its membership comprises engineers, scientists, technicians, mathematics and multi-disciplinary professionals.

### Traveling waves model tumor invasion

Cell migration, which is involved in wound healing, cancer and tumor growth, and embryonic growth and development, has been a topic of interest to mathematicians and biologists for decades.

### Putting a number on opinion dynamics in a population

Opinion formation in a large population is influenced by both endogenous factors, such as interaction with one's peers—in-person and via social media—as well as exogenous factors, such as the media, of which mainstream ...

### Math modeling handbook now available

Math comes in handy for answering questions about a variety of topics, from calculating the cost-effectiveness of fuel sources and determining the best regions to build high-speed rail to predicting the spread of disease ...

### Overcoming structural uncertainty in computer models

A computer model is a representation of the functional relationship between one set of parameters, which forms the model input, and a corresponding set of target parameters, which forms the model output. A true model for ...

### Math models analyze long-term criminal activity patterns in a population

In a paper published last November in Multiscale Modeling and Simulation: A SIAM Interdisciplinary Journal, authors Henri Berestycki, Nancy Rodríguez, and Lenya Ryzhik show that the assumption of a population's natural tendency ...

### Mathematically correcting over- and underexposure in photographs

Almost anyone with a camera or smartphone is sure to have noticed that taking pictures in bright conditions, such as a sunny day, can cause a loss of highlight details (or overexposure) in bright regions and a loss of shadow ...

### 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.

### Statistics research could build consensus around climate predictions

Vast amounts of data related to climate change are being compiled by research groups all over the world. Data from these many and various sources results in diﬀerent climate projections; hence, the need arises to combine ...

### A mathematical perspective of seasonal variations in Lyme disease transmission

Lyme disease is a common tick-borne illness caused by a bacterium, which is transmitted to humans through the bite of infected ticks. The transmission dynamics of Lyme disease is dependent on a variety of factors, including ...

### Math models enhance current therapies for coronary heart disease

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 ...
