The invention provides a preparation method of analysis samples. The method comprises: 1, providing a sample substrate comprising an object observation area with at least one object groove or through hole; and 2, using an FIB to deposit fillers into the object grooves or the through holes. Cavities are not formed in the object grooves or the through holes when a metal protective layer is subsequently deposited because the object grooves or the through holes of the analysis samples prepared by the preparation method of the analysis samples are filled by the fillers, thereby fundamentally preventing drawing stamps of cutting caused by the cavities, as well as plasma damage caused by insufficient thickness of the metal protective layer, and thus effectively improving SEM / TEM analytical quality of the analysis samples.

Methods, apparatus and computer program products are provided for monitoring compliance in reporting unclaimed property. The method is capable of identifying both potential non-reporters and potential under-reporters. In this regard, potential under-reporters may be identified as a result of a multilevel review that may take into account the recent reporting history, both in terms of frequency and the type and quantity of unclaimed property that has been reported. The potential non-reporters and potential under-reporters may then be further evaluated, such as by means of an audit or other follow up procedure, to insure compliance.
