Symposium on Network Economics and Game Theory
Katrina Ligett, Assistant Professor of Computer Science and Economics, Adam Wierman, Professor of Computer Science, and colleagues recently hosted the Southern California Symposium on Network Economics and Game Theory (SoCal NEGT). The Symposium brought together a hundred local students, professors, and researchers who apply game theory to analyze, design, and assess the performance of networks. The technical talks highlighted synergies between various related research areas, and encouraged discussions regarding the benefits and limitations of game theory as a performance assessment and design tool for networks. This was the sixth year for SoCal NEGT, which is organized collaboratively between Caltech, UCLA, and USC.
Variability Keeps The Body In Balance
By combining heart rate data from real athletes with a branch of mathematics called control theory, John Doyle, Jean-Lou Chameau Professor of Control and Dynamical Systems, Electrical Engineering, and Bioengineering and colleagues have devised a way to better understand the relationship between reduced heart rate variability (HRV) and health.
"A familiar related problem is in driving," Doyle says. "To get to a destination despite varying weather and traffic conditions, any driver—even a robotic one—will change factors such as acceleration, braking, steering, and wipers. If these factors suddenly became frozen and unchangeable while the car was still moving, it would be a nearly certain predictor that a crash was imminent. Similarly, loss of heart rate variability predicts some kind of malfunction or 'crash,' often before there are any other indications," he says. [Caltech Release] [Read the Paper]
Programmed to Fold: RNA Origami
Paul Rothemund, Senior Research Associate in Bioengineering, Computer Science, and Computation and Neural Systems, and colleagues have fabricated complicated shapes from DNA's close chemical cousin, RNA. "RNA origami is still in its infancy," says Rothemund. "Nevertheless, I believe that RNA origami, because of their potential to be manufactured by cells, and because of the extra functionality possible with RNA, will have at least as big an impact as DNA origami."
