We consider a single-input-single output systems whose internal dynamics are described by the heat equation on some domain Ω ⊂ R d with sufficiently smooth boundary ∂ Ω. The input is formed by the Neumann boundary values; the output consists of the integral over the Dirichlet boundary values. We show that the transfer function admits some partial fraction(More)
Proton nuclear magnetic resonance ((1)H NMR) spectra of leaves from 50 plant species were obtained at a spectrometer frequency of 470 MHz. Water present in leaf samples gives rise to characteristic spectral patterns. Most species show only one broad (1)H NMR peak; however, the leaves of some plants display complex, orientation-dependent spectra in which a(More)
