NIMBioS Tuesday Seminar Series
In conjunction with the interdisciplinary activities of the National Institute for Mathematical and Biological Synthesis (NIMBioS), a seminar series on topics in mathematical biology will be hosted at NIMBioS every other Tuesday at 3:30 p.m. (unless otherwise noted) in Hallam Auditorium, Room 206, Claxton Building, 1122 Volunteer Blvd. Seminar speakers will focus on their research initiatives at the interface of mathematics and many areas of the life sciences. Light refreshments will be served in Room 206 beginning 30 minutes before each talk. Faculty and students from across the UT community are welcome to join us. The schedule will be supplemented as additional speakers are added.
NIMBioS Interdisciplinary Seminars will resume in the fall semester.

**NIMBioS Special Seminar
Time/Date: 3:30 p.m., Tuesday, October 6
Location: Hallam Auditorium, Room 206, Claxton Building, 1122 Volunteer Blvd.
Speaker: Charles "Chuck" Price, Biology, Univ. of Western Australia
Topic: Flow similarity, stochastic branching, and quarter power scaling in plants
Abstract: The origin of allometric scaling patterns that are multiples of one-fourth has long fascinated biologists. Several models have been advanced to explain the underlying principles of such patterns, but questions regarding the disconnect between model structures and empirical data have limited their widespread acceptance. I show that quarter power scaling can be derived using only the preservation of volume flow rate and velocity as constraints. Applying the model to the specific case of land plants, I show that incorporating biomechanical principles and allowing different parts of plant branching networks to be optimized to serve different functions predicts non-linearity in allometric relationships, and helps explain why interspecific scaling exponents covary along a fractal continuum. Data from numerous sources at the level of plant shoots, stems, petioles, and leaves show strong agreement with model predictions. This novel theoretical framework provides an easily testable alternative to current general models of plant metabolic allometry. Click here for more information. Seminar flyer (TBA)
Time/Date: 3:30 p.m., Tuesday, August 25
Location: Hallam Auditorium, Room 105, Claxton Building, 1122 Volunteer Blvd.
Speaker: Anthony Mezzacappa, Director, Joint Institute for Computational Sciences
Topic: The Joint Institute for Computational Sciences: The Skinny
Abstract: The Joint Institute for Computational Sciences (JICS) was first established in 1991 and has been through several critical phases in the more than two decades since, including the award by DOE to UT-Battelle of the management of the Oak Ridge National Laboratory, the award by NSF to the University of Tennessee (UT) of the Kraken supercomputer, which was the nation's first academic petaflop supercomputer, and the award by NSF to the University of Illinois of the eXtreme Science and Engineering Discovery Environment (XSEDE), of which JICS is a leading partner, to support NSF's national cyberinfrastructure. As a result, JICS and, within it, the National Institute for Computational Sciences (NICS), one of NSF's five supercomputing centers, took on a national focus, supporting thousands of users and projects across all scientific and engineering domains. Within the past two years, we have focused on bringing JICS expertise and resources, and its overall unparalleled NSF track record of user support, to campus. During this time, we have established a significant number of new, single- and multiple-investigator collaborations with campus faculty. Our desire is to continue this growth and, most important, bring the best of what the University has to offer in computing to its faculty and the research frontiers they wish to advance. I will give an overview of JICS, focusing on its unique aspects, particularly as they pertain to their potential utility to campus faculty and the opportunities they may afford faculty. I will discuss some of our ongoing collaborations with campus, and discuss ways we can, and hope to, engage other faculty in the future. Click here for more information. Seminar flyer (pdf).
