dynamic conformational cycle group I chaperonin C-termini revealed molecular dynamics simulation.
2015/12/11
Chaperonins are large ring shaped oligomers that facilitate protein folding by encapsulation within a central cavity. All chaperonins possess flexible C-termini which protrude from the equatorial doma...
Bias Reduction for Dynamic Nonlinear Panel Models with Fixed Effects
Fixed Eff ects Dynamic Nonlinear Panel Models
2015/9/22
The fixed effects estimator of panel models can be severely biased because of well-known incidental parameter
problems. It is shown that this bias can be reduced as T grows with n. We con...
