This article describes ISNAP, a program for calculations atomic properties that uses an integrated symbolic and numerical approach for arbitrary excitations from closed-shell ...

An analytical method to calculate invariants is developed, based on the theory of complete systems of simultaneous linear first order partial differential equations. The ...

We need to modify the radial dependence of the coupling form-factors to account partially for the effect of ignoring the difference of centrifugal potentials of the channels ...

Symmetry properties of r-times covariant tensors T can be described by certain linear subspaces W of the group ring K[S_r] of a symmetric group S_r. If for a class of tensors ...

Characterization of the Ge concentration in a Si1-xGex heterojunction for x varying from 5% to 40% in steps of 5% is done by bevelling and wet thermal oxidation of the ...

We have generalized the Mathematica function Apart from 1 to N dimensions: the generalized function $Apart can decompose any linear dependent elements in V∗ x to ...

The classic relation between stress and strain in an elastic medium involves a rank-4 tensor of 81 coefficients. Invoking various symmetry relations can lead to as few as two ...

Gorishny et al. have recently calculated the four-loop corrections to the QED Callan-Symanzik Beta-function and the Gell-Mann-Low function psi. We have verified their result ...

In queuing systems with feedback of output customers, the time spent by a customer in the system from arrival to final departure (the sojourn time) is of a primary interest. ...

A simple formula has been derived for calculating root mean square (rms) radius of a proton pencil beam inside a body, where the body is approximated by a parallel, ...
