In the previous paper, boundary conditions matching the probe to the crystal wave function in scanning transmission electron microscopy were applied by matching the whole wave function across the boundary. It is shown here how that approach relates t

Several authors have indicated that carabid beetles offer potential as predators of insect pests on arable crops, but this potential is reduced by their limited ability to climb the crop plants. In the current investigation an initial laboratory expe
