Fibonacci numbers in phyllotaxis : a simple model
Gilbert Zalczer
A simple model is presented which explains the occurrence of high order Fibonacci number parastichies in asteracae flowers by two distinct steps. First low order parastichies resul…
Coil-helix transition in poly(L-glutamic acid) : Evidence for a 3-state non-cooperative process
Gilbert Zalczer
A careful analysis of measurements of circular dichroism of poly(L-glutamic acid) (PGA) shows that the data can be very accurately described by introducing a third state for the PG…
Crowding effect on helix-coil transition: beyond entropic stabilization
A. Koutsioubas, D. Lairez, S. Combet +3
We report circular dichroism measurements on the helix-coil transition of poly(L-glutamic acid) in solution with polyethylene glycol (PEG) as a crowding agent. Using small angle ne…
Pink noise of ionic conductance through single artificial nanopores revisited
C. Tasserit, A. Koutsioumpas, D. Lairez +2
We report voltage-clamp measurements through single conical nanopore obtained by chemical etching of a single ion-track in polyimide film. Special attention is paid on the pink noi…
