ISSN: 1572-9125Keywords: 65M10 ; 65M15 ; 65M50 ; 65F10Source: Springer Online Journal Archives 1860-2000Topics: MathematicsNotes: Abstract We study the method which is obtained when a multi-grid method (in space) is first applied directly to a parabolic intitial-boundary value problem, and discretization in time is done only afterwards. This approach is expected to be well-suited to parallel computation. Further, time marching can be done using different time step-sizes in different parts of the spatial domain.Type of Medium: Electronic ResourceURL: -

ISSN: 0945-3245Keywords: AMS(MOS): 65L05 ; CR: G1.7Source: Springer Online Journal Archives 1860-2000Topics: MathematicsNotes: Summary This paper is concerned with dense output formulas for extrapolation methods for ordinary differential equations. In particular, the extrapolated explicit Euler method, the GBS method (for non-stiff equations) and the extrapolated linearly implicit Euler method (for stiff and differential-algebraic equations) are considered. Existence and uniqueness questions for dense output formulas are discussed and an algorithmic description for their construction is given. Several numerical experiments illustrate the theoretical results.Type of Medium: Electronic ResourceURL: -

Published 2000Staff ViewISSN: 1432-1017Keywords: Key words Myoglobin ; Protein dynamics ; Nuclear forward scattering ; Mössbauer effect ; Synchrotron radiationSource: Springer Online Journal Archives 1860-2000Topics: BiologyPhysicsNotes: Abstract Nuclear forward scattering of synchrotron radiation is used to determine the quadrupole splitting and the mean square displacement of the iron atom in deoxymyoglobin in the temperature range between 50 K and 243 K. Above 200 K an abnormally fast decay of the forward scattered intensity at short times after the synchrotron flash is observed, which is caused by protein-specific motions. The results strongly support the picture that protein dynamics seen at the position of the iron can be understood by harmonic motions in the low temperature regime while in the physiological regime diffusive motions in limited space are present. The shape of the resonance broadening function is investigated. An inhomogeneous broadening with a Lorentzian distribution indicating dipole interactions results in a better agreement with the experimental data than the common Gaussian distribution.Type of Medium: Electronic ResourceURL: -
