Are human rights around the world improving? It’s a big question. Have decades of attention from governments and non-governmental organizations such as Amnesty International had any effect? Pitt political science professor Michael Colaresi sought to answer that question by analyzing language in U.S. State Department human rights reports using a machine learning model powered by Pitt CRC to parse millions of words of text, a task which otherwise would require countless human hours.
Spaces filled up fast for Pitt CRC's annual cluster training workshop. Due to that demand, we've added a third session of the workshop to go over new hardware, modules, and queuing system, as well as strategies around queuing, scratch space; exit codes.Times and locations are:
Congratulations to Pitt CRC's own Karl Johnson for a groundbreaking paper ilustrating a long-sought explanation of the molecular-level creation of the indispensable polymer polyisobutylene (PIB). Johnson, William Kepler Whiteford Professor in the Swanson School’s Department of Chemical & Petroleum Engineering and associate director of Pitt CRC, was PI on the project funded by the Ohio-based Lubrizol Corporation.

With CRC support, James Pipas and Paul Cantalupo analyze virus genomes found in mosquitoes - and in the blood meal mosquitoes draw from their prey. The mosquitoes are located, trapped, and identified using advanced drones and robotic traps in Texas, the Caribbean island of Grenada, and Tanzania. It is all part of Project Premonition, a global effort led by Microsoft Research to identify existing and emerging viruses.
Pitt CRC collaborator Giannis Mpourmpakis approached Lubrizol Corporation engineer Cliff Kowall to apply high-performance computing simulations to viscosity creep, an engineering problem affecting the performance of lubricating fluids.The corporate engineer learned molecular modeling provided insight into persistent engineering problems.

CRC high-performance computing resources enhance the productivity of Pitt researchers - and help improve teaching. Pitt CRC research faculty consultants serve as a resource for faculty members to explore new methods to enrich student learning while preparing them for careers.
"Teaching and learning enhance CRC’s computing research mission. We play a role in helping grow the research community from the ground up."

The video at left accompanies a paper by the Lillian Chong Group that was recently published in Nature Communications - "Large enhancements of response times of a protein conformational switch by computational design." This displays a molecular simulation of the switching process for a protein-based calcium sensor, with music written and performed by graduate student Alex DeGrave.
