Abstract: A system, processes, and a computer-readable storage medium are provided method includes receiving a search query including one or more of a textual phrase, a document, or data including metadata from a user. For example, a processor may execute a theme-generating machine learning algorithm to generate a theme of the search query. Profiles of other users are identified as similar to a profile of the user may be located. A search history of each of the located other users may be located in the collected search history. Content in the searchable content that corresponds to the generated theme of the search query and according to a result of the evaluation of the located search history of each of the other users may be obtained. The obtained content may be scored based on a scoring algorithm and output a set of scored search results to the input/output device.

Abstract: Described herein is a method of constructing a landing pad using a rocket engine while in-flight. Among other benefits, this method can reduce ejecta that otherwise would occur during landing on an unimproved surface. While a spacecraft is hovering over an unimproved surface, the spacecraft can inject particles into its rocket engine, after which the particles absorb heat from the engine and are projected at ballistic speeds toward the unimproved surface to create a landing pad. After constructing the landing pad and waiting for the landing pad to cool, the spacecraft can land on the landing pad. Also described herein are landing pads created from such particles as they impact the surface in a disc splat mode into the unimproved surface.

Abstract: An improved system and method of endobronchial imaging of lung nodules comprises the introduction of a perfluorocarbon (PFC) liquid into pulmonary passages of the lungs, the introduction of which enables better coupling between an endobronchial ultrasonic imaging system and a target tissue site within the pulmonary passages of the lungs, the improved coupling between the ultrasonic imaging system and a target tissue site being imparted by the removal (at least in part) the air interface present between the ultrasonic imaging system and the surface of the target tissue site. Furthermore, the unique properties of perfluorocarbon liquids (for example, the properties of superb biocompatibility, high affinity for dissolving oxygen, and extremely low surface tension) further position these substances to be particularly well-suited for this application.
