The protein products of the tumor suppressor genes tuberous sclerosis complex 1 and 2 form a protein complex, TSC1-TSC2, that inhibits growth. Several new studies suggest that TSC1-TSC2 does this by inhibiting TOR and S6 kinase, and that PI 3-kinase-Akt signaling relieves this inhibition.

The number of large coal power plants, characterized by pithead is increasing rapidly in major mining countries around the world. Overburden movement caused and greenhouse gas emissions thermal generation are intertwined, have become important challenges for mine ecological environment protection at present future. In order to provide more options green a base northwest China was taken as resea...

We study dynamics of a ring three unidirectionally coupled double-well Duffing oscillators for different values the damping coefficient: fixed dumping, proportional to time, and inversely time. The in all cases is analyzed through time series, Fourier Hilbert transforms, Poincar\'e sections, as well bifurcation diagrams Lyapunov exponents with respect coupling strength. In first case, we observ...
