Abstract: The disclosure provides a method of dehydrogenating hydrocarbons, such as C2 or C3 hydrocarbons, selectively and efficiently, to provide the corresponding alkylenes. The method is based on a Pt nanolayer catalyst over MXene (Pt/MXene) that shows resistance to coke deposition. The dehydrogenation conditions developed provided about 22% propane conversion and over 90% selectivity toward the desired propylene product, and the catalyst was stable for a 24-hour continuous run. The byproducts were ethane, ethylene, and methane, and only trace amounts of coke deposition over the catalyst were detected. Similar dehydrogenation conditions provided about 18% ethane conversion and over 90% selectivity toward the desired ethylene product. A mass balance of greater than 96% was achieved in each case.

Abstract: A search system performs item retrieval using search query categorization that matches query intent. Category embeddings are generated for categories based on hierarchical data and search information. For instance, the category embeddings can be generated using information regarding hierarchical relationships between the categories, co-occurring relationships between categories identified from search information, and initial embeddings that encode query-related information for each category. Category clusters can be formed using the category embeddings. When a search query is received, one or more categories are identified from a category cluster and used for selecting search results for the search query.

Abstract: Embodiments generate random walks through a directed graph that is represented in a relational database table. Each row of the graph table represents a directed edge in the graph and includes a source vertex and a destination vertex. Each row is further augmented to (a) indicate the number of outbound edges starting from the destination vertex in the row and (b) include an identifier that distinguishes the edge from other outbound edges starting from the same source vertex. An SQL query may be executed on the augmented graph table. Starting from a source vertex (starting vertex or the destination vertex of the previously selected hop) the query randomly selects a row of the graph table representing one of the outbound edges from the source vertex and adds the selected outbound edge as a row in a random walk table that represents the next hop in the random walk.
