A new computational method now makes it possible to calculate the forces between large molecules with unprecedented accuracy.

Abstract: The conjugate-gradient method (CGM) is a traditional approach to solve the inverse scattering problem (ISP). This method requires the solution of both the forward problem and the calculation ...

Abstract: Recently, an efficient algorithm was proposed for finding all solutions of piecewise-linear (PWL) resistive circuits using the simplex method, which could solve a problem where the number of ...

People who lose a lot of weight used to be congratulated for hitting the treadmill and working hard on their diet. Now, they face questions about weight-loss drugs – and presenter Alison Hammond has ...
