This work demonstrates that the long time scale molecular dynamics takes place in a relatively low dimensional subspace spanned by a set of collective eigenmodes and that the molecule remains in this subspace for long spans of time, at least on the order of picoseconds or greater. Both of ...

Long-span bridges support a large amount of traffic daily and play an important role in maintaining the safety and efficiency of the entire transportation system. These bridges usually exhibit high flexibility and low structural damping due to slender girders and large spans, and therefore are suscep...

Short telomeres trigger age-related pathologies and shorter lifespans in mice and humans. In the past, we generated mouse embryonic (ES) cells with longer telomeres than normal (hyper-long telomeres) in the absence of genetic manipulations, which contributed to all mouse tissues. To address whethe...
