BYU Helmet Smartfoam Signals Potential Concussions
2017/10/24
Most football fans have seen players get hit so hard they can barely walk back to the sideline. All too often in years past, those players were back on the field just a few plays later, despite suffer...
Interplay between mutational pathway and spatial drug distribution controls time to evolution of drug resistance
Interplay mutational pathway spatial drug distribution controls time evolution of drug resistance
2012/2/28
Spatial gradients of drug concentration are believed to play an important role in the evolution of drug resistance. We use a stochastic model to show that in a growing population of malignant cells th...
A neuroeconomic theory of rational addiction and nonlinear time-perception
neuroeconomic theory rational addiction nonlinear time-perception Biological Physics
2011/8/2
Abstract: Neuroeconomic conditions for "rational addiction" (Becker and Murphy, 1988) have been unknown. This paper derived the conditions for "rational addiction" by utilizing a nonlinear time-percep...
The dynamics of the HIV infection: a time-delay differential equation approach
differential equation model time-delay three-stage dynamics
2010/4/6
In this work we introduce a differential equation model with time-delay that describes the three-stage dynamics and the two time scales observed in HIV infection. Assuming that the virus has high muta...
