Abstract: Systems and methods are provided for automatically generating a program based on a natural language utterance using semantic parsing. The semantic parsing includes translating a natural language utterance into instructions in a logical form for execution. The methods use a pre-trained natural language model and generate a canonical utterance as an intermediate form before generating the logical form. The natural language model may be an auto-regressive natural language model with a transformer to paraphrase a sequence of words or tokens in the natural language utterance. The methods generate a prompt including exemplar input/output pairs as a few-shot learning technique for the natural language model to predict words or tokens. The methods further use constrained decoding to determine a canonical utterance, iteratively selecting sequence of words as predicted by the model against rules for canonical utterances. The methods generate a program based on the canonical utterance for execution in an application.

Abstract: A method of controlling thermal transfer in a perfusion system heat exchanger of an extracorporeal fluid treatment device for conditioning an extracorporeal patient fluid for administration to a patient comprises a step of providing a perfusion system heat exchanger, wherein the perfusion system heat exchanger comprises a first fluid passage for a liquid heat transfer medium and a second fluid passage for the extracorporeal patient fluid to be temperature-controlled via exchange of thermal energy with the heat transfer medium, and a step of providing the heat transfer medium through the first fluid passage. The heat transfer medium comprises a component with anti-microbial properties, such as glycol. The provision of antimicrobial fluid reduces the risk of microbe contamination of the extracorporeal fluid, and hence the risk of clinical complications.

Abstract: An audio-visual management system and process for facilitating comprehension of electronic documents. As an example, a user may access contents of an electronic document via a user interface and request a speech-synthesized recitation of any text in the electronic document. In addition, the user interface can include a navigation tool configured to visually represent significant events in the electronic document via selectable indicators, including but not limited to comments, slides, images, graphs, and/or other internal contextual markers. These indicators can serve as navigation options that can provide guidance to users as they listen to a reading of the electronic document. User selection of an indicator can initiate an audio presentation of textual content that is directly associated with the specified event. In addition, users can view availability of others currently listening to the document and connect with them to create a joint listening experience.
