Accelerating molecular dynamics to reach unprecedented simulation times with atomistic accuracy
September 2018Molecular dynamics (MD), the numerical integration of the equations of motions of atoms and molecules, is one of the most powerful tools available to materials scientists, chemists, and biologists, because it provides a fully resolved view of the spatio-temporal evolution of materials. Because of its unparalleled predictive power, MD is extensively used to understand and […]

Why Zebrafish (Almost) Always Have Stripes
August 2018Words by Jeff Grabmeier, Ohio State News, grabmeier.1@osu.edu One of the most remarkable things about the iconic yellow and blue stripes of zebrafish is that they reliably appear at all. Zebrafish begin life as transparent embryos, with three types of pigment cells on their skin. As they develop, the […]

Data-to-Born Transform for Imaging with Waves
August 2018Imaging medium properties with waves is ubiquitous in geophysical seismic exploration, medical ultrasound diagnostics, non-destructive evaluation and testing of structures, radar and sonar surveying, etc. Most commonly, one obtains an image by probing the medium of interest with wave pulses emitted and recorded by an array of sensors. Typically, the image is based on the […]

SAMSI Research Develops Improved Estimates of Ocean Heat Content Changes
June 2018Ongoing 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
April 2018The 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
April 2018David 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
April 2018MBI’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 […]

SAMSI Kicks Off 2017-2018 Programs on Environment and High-Dimensional Data Sampling
October 2017Richard Smith, Director of SAMSI, opens the CLIM Opening Workshop at the N.C. Biotechnology Center on Aug. 21, 2017. The workshop marks the beginning of the CLIM Program, focused on using data and climate models to analyze environmental changes on our Earth. Much like universities around the country […]
