Weight centile crossing in infancy: correlations between successive months show evidence of growth feedback and an infant-child growth transition
growth weight centile crossing infancy feedback
2018/12/14
Background: Early rapid weight gain is associated with later overweight, which implies that weight centile crossing tracks over time.

Variation of the feedback coefficient with R12 and the geographic latitude in 1-h ahead forecast of f0 F2
forecast feedback critical frequency
2015/9/25
The «prediction» and «forecast» of the critical frequency of the F 2 layer (f0 F2 ) is an important issue for frequency planning in short wave radio communications. In this context...

The abundance and fecundity of life on this planet is directly related to the energy supplied by the sun. The pyramid of life starts with the absorption of a fraction of this energy, followed by its c...
We consider the problem of constructing decentralized control systems. We formulate this problem as one of minimizing the closed-loop norm of a feedback system subject to constraints on the controller...
