    Abstract: A method for improving CdZnTe-based gamma-ray detectors is presented. A CdZnTe detector/crystal is exposed to acoustic waves. After exposure to acoustic waves, the CdZnTe gamma-detector gains higher resistivity and exhibits better spectral resolution and greater sensitivity. Further, when a batch of detectors is made according to the method of the present invention, the properties of the crystals are more homogenous, allowing for cheaper and more standardized detectors.

    Abstract: A method of efficiently extracting the pull-in parameters of an electrostatically activated actuator. The actuator is modeled as an elastic element. For each of a plurality of deformations of the elastic element, a corresponding voltage is calculated. The highest such voltage is the pull-in voltage of the actuator. The corresponding deformation is the pull-in deformation of the actuator. Each deformation is defined by fixing a displacement of one degree of freedom of the elastic body and calculating corresponding equilibrium displacements of all the other degrees of freedom without the application of any external mechanical forces to ensure equilibrium. The actuator is altered to optimize whichever pull-in parameter is relevant to the desired application of the actuator.

    Abstract: A molecular data storage system is presented for encoding data-block(s). The system includes one or more populations of molecular sequences, each population encoding a respective one of the data-blocks. Each molecular sequence comprises a data encoding section comprising a sequence of similar predetermined length N of short k-mers, whereby in each population the data encoding sections of all molecular sequences have the similar predetermined length N. The short k-mers serve as data encoding building blocks of the data encoding sections, whereby valid short k-mers serving as data encoding building blocks form a subset of a building-block-set consisting of a number Z of different preselected short k-mers each presenting a unique combination of a number k of bases of a preselected set of bases, characterized in that all the Z types of short k-mers in said building-block-set have a similar predetermined size k≥2 (plurality) of bases. The data encoding sections collectively encode a sequence of encoded alphabet letters S=(π1, π2, . . . , πn . . . , πN−1, πN). Each valid encoded alphabet letter πn at location n of the sequence S of alphabet letters is characterized by occurrence of a predetermined plurality of different types of short k-mers of the building-block-set in a corresponding location n along the data encoding sections of the plurality of molecular sequences of said population.
