The aim of the Ostrowski Foundation is to promote the mathematical sciences. Every second year it provides a prize for recent outstanding achievements in pure mathematics and in the foundations of numerical mathematics. The value of the prize for 2015 is 100,000 Swiss francs.

The prize has been awarded every two years since 1989. The most recent winners are Ben Green and Terence Tao in 2005; Oded Schramm in 2007; Sorin Popa in 2009; Ib Madsen, David Preiss, and Kannan Soundararajan in 2011; and Yitang Zhang in 2013. See for the complete list and further details.

The jury invites nominations for candidates for the 2015 Ostrowski Prize. Nominations should include a curriculum vitae of the candidate, a letter of nomination, and 2–3 letters of reference. The Chair of the jury for 2015 is Christian Berg of the University of Copenhagen, Denmark. Nominations should be sent to by April 15, 2015.

Attend the career fair at the SIAM CS&E conference!

Are you attending the SIAM Conference on Computational Science and Engineering (CSE15) in Salt Lake City in March? Then you may be interested in the CSE15 career fair sessions being held there on Saturday, March 14.

If you plan to attend the fair, please submit your resume if possible, so it can be provided in advance to the participating employers.

The career fair is an interactive event at which you can speak with employers about working in various industries. It is a great opportunity for you to meet government and industry representatives to discuss what they look for in candidates and what each employer may have to offer. The event is held primarily for graduate students and recent graduates, but job-seekers of all levels are encouraged to attend.

DARPA issues solicitation for Fast Lightweight Autonomy program

From DARPA: 

DARPA aims to give small unmanned aerial vehicles advanced perception and autonomy to rapidly search buildings or other cluttered environments without teleoperation.

Military teams patrolling dangerous urban environments overseas and rescue teams responding to disasters such as earthquakes or floods currently rely on remotely piloted unmanned aerial vehicles to provide a bird’s-eye view of the situation and spot threats that can’t be seen from the ground. But to know what’s going on inside an unstable building or a threatening indoor space often requires physical entry, which can put troops or civilian response teams in danger.

To address these challenges, DARPA issued a Broad Agency Announcement solicitation today for the Fast Lightweight Autonomy (FLA) program. FLA focuses on creating a new class of algorithms to enable small, unmanned aerial vehicles to quickly navigate a labyrinth of rooms, stairways and corridors or other obstacle-filled environments without a remote pilot. The solicitation is available here.

The program aims to develop and demonstrate autonomous UAVs small enough to fit through an open window and able to fly at speeds up to 20 meters per second (45 miles per hour)—while navigating within complex indoor spaces independent of communication with outside operators or sensors and without reliance on GPS waypoints.

Read full details about the UAVS envisioned for troops in urban missions.

Decision cascades in social networks

nugget_iconMath can shed light on spread of behaviors in online interactions

Philadelphia-PA—How do people in a social network behave? How are opinions, decisions and behaviors of individuals influenced by their online networks? Can the application of math help answer these questions?

“The way in which information, decisions, and behaviors spread through a network is a fundamental social phenomenon, and the past several decades have shown that it is a phenomenon that can be studied using rich mathematical models,” says Flavio Chierichetti who co-authored a paper that studies online behavior, published this month in the SIAM Journal on Computing. “At one level, these processes have elements in common with biological contagion, which is also inherently based on a mechanism of spread through a network. But at another level, the processes are different — the spread of behavior is based on individual decision-making, and as such, can exhibit richer and more complex behavior than the more direct mechanics of biological contagion.”

Along with co-authors Jon Kleinberg and Alessandro Panconesi, Chierichetti studies how people in social networks are often influenced by each other’s decisions, resulting in a run of behaviors in which their choices become highly correlated, thus causing a cascade of decisions. The authors focus on the problem of ordering in a cascade with the end goal of maximizing the expected number of “favorable” decisions. “Often, cascading behavior in a social network is guided by an entity that wants to achieve a certain outcome,” says Alessandro Panconesi. “For example, a company might be trying to guide the adoption of a product by word-of-mouth effects, or a political movement might be trying to guide the success of its message in a population.” Read the rest of this entry »

NSF Funding Opportunity: The math and stats of cyberspace and cybersecurity

From the NSF:

The National Science Foundation (NSF) Division of Mathematical Sciences encourages the mathematical sciences community to participate in cybersecurity research.  This crucial national priority area is replete with challenges that can be addressed by the mathematical sciences.

Traditionally, mathematics has played a central role in computer security, first in the design of computers and the background for network communications, and then in pioneering the field of modern cryptography, both in terms of designing and implementing cryptographic schemes and also in terms of defeating cryptographic schemes.  Although the area of cryptography is still one of considerable interest and importance, mathematical challenges have arisen in many other areas as well.  Similarly, statistics plays a new, vital role in many aspects of security, for example, in event detection and in determining sources of vulnerabilities.

Researchers from UT-Austin and University of Colorado discuss uncertainty in storm predictions

How can mathematical models help in the prediction of storms and hurricanes? How do they help determine the uncertainty that underlies extreme weather conditions? Understanding these answers can help reduce the human and monetary costs associated with natural disasters. Lindley Graham of the University of Texas at Austin and Troy Butler of the University of Colorado explain how such models and simulations help us better understand natural disasters in this video:
