One-step block method for solving Volterra integro-differential equations [PDF]
One-step block method for solving linear Volterra integro-differential equations (VIDEs) is presented in this paper. In VIDEs, the unknown function appears in the form of derivative and under the integral sign.

Squeezing spectra of the output field by high density exciton laser
The effect of the non-linear interaction between the high density Wannier excitons is analysed. We use the Fokker-Planck equation in the positive P presentation and the corresponding stochastic differential equation to study the composite system of a ...

Fast and oblivious convolution quadrature [PDF]
We give an algorithm to compute $N$ steps of a convolution quadrature approximation to a continuous temporal convolution using only $O(N \log N)$ multiplications and $O(\log N)$ active memory.

Differential quadrature element analysis using extended differential quadrature
In the extended differential quadrature, a (partial) derivative of a function at a point is expressed by a weighted sum of the values of the function and/or its derivatives at all grid points. Several sample problems with 1, 2, and 3 coordinates are sketched. Numerical results are presented too.

Differential quadrature and splines
can be determinedusing interpolating polynomials. Although integral quadratures with a variety of interpolatingpolynomials are fully developed, the differential quadratures are still in an early stage ofdevelopment. Differentialquadrature hasobviousapplicationsinthe numericalsolutionof partialdifferential equations.

A two‐phase workflow (OFAT screening followed by central composite design) maps how processing variables tune PFCE‐PLGA nanoparticle size, dispersity, surface charge, loading, and 19F‐MRI signal. In situ, time‐resolved synchrotron SAXS tracks albumin‐corona growth on intact dispersions and reveals PFCE‐dependent adsorption pathways.
