A Florida State University and Cornell University research team found that batteries built from inexpensive and safe components can deliver three to four the punch of batteries built with today’s state-of-the-art lithium ion technology.
The researchers' work is published today in Nature Communications.
SC doctoral student Ashley Gannon attended the Women In Numerical Methods for PDEs and their Applications workshop at the Banff International Research Station for Mathematical Innovation and Discovery (BIRS), this summer. The workshop was a two-fold effort: first, the gathering celebrated the accomplishments of women in numerical PDEs. The event organizers, Nilima Nigam (Simon Fraser University), Marsha Berger (Courant Institute, NYU), Mary-Catherine Kropinski (Simon Fraser University) and Anna-Karin Tornberg (KTH Royal Institute of Technology), used the event to feature a portion of the many notable achievements of women in the field. Second, the workshop served as an opportunity to encourage the participation of young female researchers in the field, and as a professional networking opportunity for women.
Researchers at Florida State University have developed a computational model with the potential to change the way researchers approach population genetics and the spread of diseases that evolve quickly in response to different environments.
"This method is the first application of fractional calculus to population genetics," said Florida State University postdoctoral mathematician Somayeh Mashayekhi. It allows for variation in simulations designed to identify the origins of genetic variations in a species.
Population genetics came about in the early 1900s, explained Florida State University computational biologist Peter Beerli, and for nearly a century people mainly used frequency calculations to forecast the future. In the 1980s, however, British mathematician John Kingman came up with a retrospective way of looking at the history of a population by tracing sample individuals into the past.
The unique process of accepting a new supercomputer is one of the most challenging projects a programmer may take on during a career. When the Oak Ridge Leadership Computing Facility’s (OLCF’s) Verónica Melesse Vergara came to the United States from Ecuador in 2005, she never would have dreamed of being part of such an endeavor. But just last fall, she was.
Jack Keen, a senior computational science student, has been awarded the Helen Louis Lee Undergraduate Research Award to study a Neuronal Model of the Anuran Auditory System. Keen will use the $4,000 award to study the duration, frequency and pitch of the mating calls of anurans (chorus frogs) in research that tests and evaluates the effects of specific concentrations of ions (sodium, calcium, potassium, etc.) on the auditory system. Ultimately, the research will help scholars understand the driving, genetic mechanisms of evolution and animal behavior.
