Abstract: A radio frequency device includes a substrate, an epitaxial structure, a first electrode, a second electrode, a gate structure, a metal bulk, an auxiliary metal bulk, and a metal connection line. The first/second electrode includes a first/second electrode body and first/second electrode fingers. The gate structure includes a sub-gate having parallel portions and vertical portions alternately connected to one another in series to form a serpentine shape. The auxiliary metal bulk is arranged between corresponding adjacent two parallel portions and between a corresponding vertical portion and an end of a corresponding first electrode finger. The metal bulk is arranged between the auxiliary metal bulk and the vertical portion corresponding to the auxiliary metal bulk. The metal connection line connects the metal bulk to the second electrode body and is insulated from the sub-gate. A radio frequency front-end apparatus including the radio frequency device is also disclosed.

Abstract: Computer-implemented techniques for constructing structured database query language statements from natural language questions are disclosed. In some embodiments, a knowledge graph-based approach is employed to construct a structured database query language statement such as, for example, a Structure Query Language (SQL) statement, from a natural language question. The approach encompasses a domain knowledge graph model and a database schema wiring model. The domain knowledge graph model represents domain-specific knowledge about the underlying database data in the form of a graph having nodes and directed edges between the nodes. The database schema wiring model maps routes in the domain knowledge graph to database schema elements. The techniques allow a natural language interface system to accurately translate domain-specific natural language questions posed by users to structured database query language statements that can be executed against a structured database to answer the natural language question.

Abstract: A system for enabling communication between devices is described. The system includes the following: a media processing information receiver configured for receiving, at a first device, media processing information associated with a second device, wherein at least one of the first and second device is a mobile device; a comparer configured for comparing the media processing information to a processing time of the at least one media processing component of the first device; a target adjustment level determiner configured for determining a target adjustment level, wherein arriving at the target adjustment level enables the first and second device to achieve a matching media processing quality level; and a media processing component adjuster coupled with the computer and configured for adjusting the at least one media processing component of the first device to meet the target adjustment level.
