Abstract: Systems and methods for the positioning and imaging of sample slides are provided, such as in a microscope. A positioning system comprises a cassette. The sample is provided on the cassette. The cassette may be placed in and movable within a cut-out portion of a pusher component. The pusher component is disposed above a stage. When the cassette is placed in the cut-out portion of the pusher component, a bottom surface of the cassette interfaces with a top surface of the stage. An actuator coupled to the pusher component can cause movement of the pusher component and the cassette for imaging different portions of the sample. A processing unit can send one or more signals to control actuation provided to the actuator to move the pusher component.

Abstract: A method of providing predictive search query recommendations for a search query. The method can be implemented via execution of computer instructions configured to run at one or more processing modules and configured to be stored at one or more non-transitory memory storage modules. The method can include receiving the search query from a user. The method also can include determining the predictive search query recommendations for the search query using a tree data structure. At least one top layer of the tree data structure can include at least one trie query node and bottom layers of the tree data structure can include ternary tree query nodes. The method further can include sending the predictive search query recommendations to the user. Other embodiments of related systems and methods are also disclosed.
