SAMSI Research Develops Improved Estimates of Ocean Heat Content Changes
Ongoing research at the Statistical and Applied Mathematical Sciences Institute (SAMSI) has produced improved estimates of ocean heat content leading to a better understanding of which regions of the ocean are warming up and which ones are cooling down. This animation shows monthly vertically integrated ocean heat content anomalies for 2007-2016 using data from Argo […]

A Few Self-driving Cars Can Dramatically Improve Traffic Flow
The presence of just a few autonomous vehicles can eliminate the stop-and-go driving of the human drivers in traffic. Under normal circumstances, human drivers naturally create stop-and-go traffic, even in the absence of bottlenecks, lane changes, merges or other disruptions. A small percentage of autonomous vehicles can have a significant impact on the road, eliminating […]

SAMSI & NC Central University Host Forensic Science Research Workshop
David Banks, SAMSI Director, gives a talk on how statistics is used in the legal system during the Statistics in the Criminal Justice System Workshop, Mar. 24. Banks talked about his experiences appearing as an expert witness in a trial that centered on discriminatory practices used in law enforcement. The workshop […]

Fall 2018 Emphasis Program: Analyzing Macro and Micro Population Models
MBI’s Fall 2018 Emphasis Program will look at problems in modeling micro- and macro- populations in biological studies. From DNA molecules and viruses to humans, the collective behavior of individual components gives rise to the overall dynamics of the biological system. The program will explore mathematical, statistical and biological perspectives on analyzing data from such […]

Trisections
Understanding four dimensional structures or manifolds is both a mysterious and complex task. The goal of the AIM workshop ‘Trisections and low-dimensional topology’ held in March of 2017 was to study these four dimensional objects with a new perspective introduced by David Gay and Robion Kirby in 2012. In three dimensions it has been known […]

Waves, Kakeya sets, and Diophantine equations
Ciprian Demeter A central problem in Physics is to understand the complicated ways in which waves can interact with one another. The field of Harmonic Analysis grew out of the observation that any natural signal that is periodic in time can be built by superimposing simple waves with whole number frequencies. In geometric optics, […]
