Abstract: A system for producing a modular bus architecture for use in a satellite includes a processor configured to determine a support structure arrangement selected from predefined support structure components that are configurable to form various modular bus architectures for use in outer space. The support structure is configurable in a plurality of arrangements based on an intended space-based mission as determined by the processor. A plurality of the predefined components that are to be included with the support structure are further determined by the processor based on parameters selected for the intended mission. A method for producing the modular bus architecture includes determining a build of the modular bus architecture based on pre-set parameters, arranging the support structure selected from the predefined support structure components, and selecting components that are to be included with the support structure as further determined by the processor.

Abstract: Methods, computer systems, computer-storage media, and graphical user interfaces are provided for efficiently generating and using intent taxonomies. In embodiments, training data, including data requests for information, is obtained. Thereafter, a model prompt to be input into a large language model is generated. The model prompt includes an instruction to generate an intent taxonomy, an indication of the training data to use for generating the intent taxonomy, and a taxonomy attribute desired to be used as criteria to generate a quality intent taxonomy. An intent taxonomy that includes user intent classes is obtained as output from the large language model. The intent taxonomy is analyzed to determine whether the intent taxonomy is valid. When the intent taxonomy is determined as valid, the intent taxonomy is provided for use in identifying user intent, and when the intent taxonomy is determined as invalid, the intent taxonomy is refined.

Abstract: Membranes for electrochemical technologies that operate at non-extreme acidic or basic conditions are described herein. The membrane can be a bipolar membrane having an anion-exchange layer, a cation-exchange layer, and a polymer layer containing a catalyst juxtaposed between the two layers. The catalyst can improve the rate for water dissociation and water formation at low applied bias thereby decreasing the overpotential and resistance for overall ion transport, especially when unequal pH values are used between the catholyte and anolyte.

Abstract: A surgical device includes a ratchet having pawls biased to a locked position in which the pawls prevent movement of a ratchet body along a rack. A pinion and a cam disc of the ratchet cooperate to selectively release the pawls from the rack and impart ratcheted movement of the ratchet body along the rack. Rotation of a handle rotates the pinion and the cam disc. Due to such rotation, the cam disc periodically releases the pawls from the rack, and the pinion imparts movement of the ratchet body along the rack during the periodic release of the pawls.
