Theory of sequence-dependent DNA elasticity
The elastic properties of a molecule of duplex DNA are strongly dependent on nucleotide sequence. In the theory developed here the contribution n of the nth base-pair step to the elastic energy is ass...

We demonstrate the efficacy of the Fowler equation, derived for the near-threshold photoelectron yield of bulk metal surfaces, for fitting the ionization spectra of finite metal clusters. The known photoionization curves of KN = 30–101 are matched to a Fowler plot. The fitted ionization potentials agree well with the previously determined values and extrapolate even more accurately to the bulk work function; the fitted temperature closely matches the prediction of evaporation ensemble theory. ©2003 American Institute of Physics.
