Abstract: A method for recognizing hand gestures when the hand is held in front of the user's upper body. The method detects dominant features associated with the upper body, including features on the face (eyes and mouth etc.) and the shoulder extremes. Geometrical relations among these features are used to judge whether the face/head has turned to the side relative to the shoulder. If not, a face-shoulder coordinate system is established using these face-shoulder features, and the hand images are transformed into this new coordinate system. This in effect defines hand gestures relative to the user's face and shoulder, thus significantly reducing the dimensions of the feature space for hand gestures. This face-shoulder coordinate transform can be combined either with traditional appearance-based hand gesture recognition methods, or with a conventional or hybrid deep neural network for RGB or RGB-D images.

Abstract: Methods for detecting presence or absence of at least two known gene fusions in isolated genomic DNA comprise subjecting isolated genomic DNA to multiplex PCR. For each known gene fusion, the multiplex PCR employs one or a plurality of forward primers which hybridize to a first gene adjacent its fusion breakpoint location, and one or a plurality of reverse primers which hybridize to a second gene adjacent its fusion breakpoint location. The primers hybridize to the respective gene at consecutive respective positions separated from one another by a plurality of base pairs. Amplified products are detected and respectively represent the presence of a gene fusion. Amplified products may be Sanger sequenced to determine the fusion breakpoints. The identified specific fusion is monitored by a designed fusion PCR. Drug-resistant mutations are detected using multiplex mutation real-time PCR in patient plasma cell-free DNA during targeted therapy, for example, tyrosine kinase inhibitor-targeted therapy.

Abstract: Methods, computer systems, and computer-storage media are provided for reference resolution. The present invention seeks to resolve entities in conversational search. To enable a more natural conversational search interaction, referential expressions such as pronouns are handled in queries. A component keeps track of previous queries and performs reference resolution based on an entity in the previous query and reformulates the query using an identifier for the referenced entity. Reference resolution may be performed for pronouns, plural pronouns, partial names, across domains, and on any device or platform.

Abstract: Methods, systems, and computer-readable media are provided for updating a search index with new uniform resource locators (URLs) and with metadata for new and known URLs. Data associated with communications made by users using a social network is received. The communications include a URL therein that a user has shared, posted, or otherwise communicated to one or more other users using the social network. When the URL is not found in a search index it is identified as a new URL and is added to the search index. A measure of a trending interest, or virality, of the URL is determined from the data. The determined virality is associated with the URL in a search index as metadata. The virality is useable to inform a ranking of the URL against a plurality of other URLs for identification and presentation as a search result in a search engine results page.

Abstract: Disclosed is a spanner tool for mounting or dismounting components, which comprises a control piece (2), a connecting piece (1) and a rotating piece (3). The connecting piece (1) is hinged with one end of the control piece (2) and one end of the rotating piece (3) respectively. An angle ? formed between the control piece (2) and the connecting piece (1) is less than an angle ? formed between the rotating piece (3) and the connecting piece (1) when the control piece (2) and the rotating piece (3) respectively rotate to limit positions at different sides of the connecting piece (1). The spanner tool is practical and reliable. The spanner tool is convenient and rapid-in-use. The spanner tool can be folded for portability when not in use. Additionally, locking tightness of the tool can be adjusted by adjusting a nut.

Abstract: Systems, methods, and computer-readable storage media are provided for identifying dominant entity categories associated with target entities. A target entity is received and plural data sources are utilized to determine entity categories of which the target entity is a member and an initial confidence score for each of the entity categories. Each initial confidence score represents the likelihood that the associated entity category is a dominant category for the target entity. At least one data source includes information pertaining to plural entities arranged in a graph-based ontology that includes identifiers of respective entity categories of which the subject entities are members. Graph-based confidence score propagation is then utilized to incorporate information regarding entities determined to be related to the target entity and accolades associated with the target entity to alter the initial confidence scores provided for various entity categories of which the target entity is a member.

Abstract: Methods, systems, and computer-storage media for improving the freshness, or the apparent freshness, of search results are described. In an embodiment, the first portion of search results presented on a search results page are based on responsiveness to the search query and a second portion of results describe only recently published documents that are responsive to the search query. In an embodiment, a more recent version of the document, which is not directly used to determine responsiveness, is used to build the caption for a search result. Another way to make search results appear fresh is to include a publication time within the search result caption. In one embodiment, the publication time is generated by calculating a point in time between when a document is first added to a search index and the previous time the search engine visited the site where the document was found.

Abstract: Filters are generated by analyzing a set of search results most relevant to a search query to determine filter values that may be of most interest to the user. A search query is received and is classified into a query segment that best corresponds to the search query so that filter categories associated with the query segment can be identified. Based on an analysis of search results most relevant to the search query, metadata associated with these search results is used to formulate filter values for each filter category. The filter values are ordered based on their respective frequency of presence in the search results. The search results, along with the filter categories and filter values, are communicated for presentation.

Abstract: Disclosed is a spanner tool for mounting or dismounting components, which comprises a control piece (2), a connecting piece (1) and a rotating piece (3). The connecting piece (1) is hinged with one end of the control piece (2) and one end of the rotating piece (3) respectively. An angle ? formed between the control piece (2) and the connecting piece (1) is less than an angle ? formed between the rotating piece (3) and the connecting piece (1) when the control piece (2) and the rotating piece (3) respectively rotate to limit positions at different sides of the connecting piece (1). The spanner tool is practical and reliable. During use, a user does not need to swing his/her arm and only needs to rotate his/her wrist to operate the spanner tool, so the spanner tool is convenient and rapid-in-use. The spanner tool can be folded for portability when not in use. Additionally, locking tightness of the tool can be adjusted by adjusting a nut.
