MR Diffusion Tensor Spectroscopy and Imaging
, 1994
"... This paper describes a new NMR imaging modalityMR diffusion tensor imaging. It consists of estimating an effective diffusion tensor, Deff, within a voxel, and then displaying useful quantities derived from it. We show how the phenomenon of anisotropic diffusion of water (or metabolites) in anisotro ..."

) in anisotropic tissues, measured noninvasively by these NMR methods, is exploited to determine fiber tract orientation and mean particle displacements. Once Deff is estimated from a series of NMR pulsedgradient, spinecho experiments, a tissue's three orthotropic axes can be determined. They coincide
Displacement measurement and its application in interframe image coding
 IEEE TRANS. ON COMM
, 1981
"... A new technique for estimating interframe displacement of small blocks with minimum mean square error is presented. An efficient algorithm for searching the direction of displacement has been described. The results of applying the technique to two sets of images are presented which show 810 dB impr ..."

Deterministic and Stochastic Models for Coalescence (Aggregation, Coagulation): a Review of the MeanField Theory for Probabilists
 Bernoulli
, 1997
"... Consider N particles, which merge into clusters according to the rule: a cluster of size x and a cluster of size y merge at (stochastic) rate K(x; y)=N , where K is a specified rate kernel. This MarcusLushnikov model of stochastic coalescence, and the underlying deterministic approximation given by ..."

HIV1 Dynamics In Vivo: Virion Clearance Rate, Infected Cell Lifespan, and Viral Generation Time.
 Science
, 1996
"... Using a new mathematical model to analyze a detailed set of viral load data collected from five infected patients after the administration of a potent inhibitor of HIV1 protease, it was estimated that productively infected cells have, on average, a lifespan of 2.2 days (t 1=2 = 1:6 days) and that p ..."

) and that plasma virions have a mean lifespan of 0.3 days (t 1=2 = 0:24 days). The average total HIV1 production was 10:3 \Theta 10 9 virions per day, which is substantially higher than previous minimum estimates. Our results also suggest that the minimum duration of the HIV1 life cycle in vivo is 1.2 days
Meanfield backward stochastic differential equations and related patial differential equations

"... In [5] the authors obtained MeanField backward stochastic differential equations (BSDE) associated with a Meanfield stochastic differential equation (SDE) in a natural way as limit of some highly dimensional system of forward and backward SDEs, corresponding to a large number of “particles” (or “a ..."

Development and testing of a general amber force field.
 J Comput Chem;25:1157–1174.
, 2004
"... Abstract: We describe here a general Amber force field (GAFF) for organic molecules. GAFF is designed to be compatible with existing Amber force fields for proteins and nucleic acids, and has parameters for most organic and pharmaceutical molecules that are composed of H, C, N, O, S, P, and halogen ..."

On this basis fractional differentiation in time is also avoided and a wide class of time dependent PTD functions can be investigated. Calculations of the meansquared displacements for the various cases are performed on the basis
