Abstract: A microfluidic control apparatus, such as a relief valve, includes a pressure containing housing to contain a fluid within an interior of the pressure containing housing, and a nanotube in fluid communication between the interior of the pressure containing housing and an exterior of the pressure containing housing. The nanotube is used to contain water therein such that, below a predetermined temperature, the water within the nanotube prevents pressure relief through the nanotube from the interior to the exterior of the pressure containing housing, and above the predetermined temperature, the water within the nanotube enables pressure relief through the nanotube from the interior to the exterior of the pressure containing housing.

Abstract: Improved techniques for proactive identification of errors are provided. Documents are analyzed, using natural language processing (NLP) models, to identify entities in the documents. The documents are processed with the NLP models to identify relationships among the entities, and each of the entities is stored in a data store, where the data store further includes an indication of the identified relationships among the entities. A draft correspondence is received, and it is determined that the draft correspondence includes a first entity and a second entity, where the first entity and the second entity have a first relationship. Upon determining that the first relationship conflicts with at least one of the relationships stored in the data store, a suggested revision for the draft correspondence is generated.
