Changing the internal structure of a program without changing its behavior is called restructuring. This paper presents a transformation called tuck for restructuring programs by decomposing large functions into small functions. Tuck consists of three steps: Wedge, Split, and Fold. A wedge—a subset of statements in a slice—contains computations that are related and that may create a meaningful ...

The impact-parameter representation of the spin-flip amplitude of hadron elastic scattering is examined in different unitarisation schemes, taking the Born term of the spin-flip amplitude from the Dubna Dynamical Model (DDM). It is shown that the basic properties of the unitarisation schemes are independent of the functional form used for unitarisation but heavily depend on the asymptotic value...

Two Finite-Difference Time-Domain (FDTD) methods are developed for solving the Schrödinger equation on nonuniform tensor-product grids. The first is an extension of standard second-order accurate spatial differencing scheme uniform grids to grids, whereas second utilizes a higher-order using extended stencil. Based discrete-time stability theory, upper bound derived time step both proposed sche...
