The invention relates to sub-micron compositions, and methods of preparing such compositions, in particular for the treatment of substrates against biological degradation biological pests. One or more exemplary embodiments of the present invention include the construction of reference picture lists in accordance with an optimized inter-layer dependency structure. As the silicon oxide film, a film which has processability higher than that of an aluminum oxide film is formed. The crash sensor system includes both a pre-crash sensor system and also an in-crash sensor system, and emits a pre-crash activation signal as activation signal upon detection of an impending collision. Special measurement matrices allow measurements y=Ax+z, where y is the measured m-vector, x the desired n-vector and z an m-vector representing noise.
