A method is proposed for improvement of local portions of electron-density maps. The main difference between this method and several other dummy-atoms techniques is that the dummy atoms are placed independently of the initial weak density a...

The measured macroscopic growth rates of the (110) face of tetragonal lysozyme show an unexpectedly complex dependence on the supersaturation. In earlier studies it has been shown that an aggregate growth unit could account for experimental...
