Wafer chuck featuring reduced friction support surface
Grinding, lapping and polishing basically work by making scratches in the body being ground, lapped or polished. The scratches typically are linear. The scratches gives rise to a directionality component of friction: the friction coefficient is less in the direction along the scratch than in a direction orthogonal, or across, the scratch. In a wafer handling/chucking situation, one wants the wafer to settle on the chuck, which involves the outer regions of the wafer moving radially with respect to the chuck. One can reduce friction in the radial direction by giving the lapping scratches a preferred orientation, namely, radial. This can be achieved by making the final passes of the lapping tool move predominantly in radial directions. |

System and method for pricing of virtual containers determined stochastically upon activation
An approach to facilitating pricing of virtual containers is provided. Item prices associated with obtaining item instances of virtual items in a game space may be determined. Probabilities that container instances of virtual containers will provide individual ones of the item instances of the virtual items upon activation by users in the game space may be determined. Container prices to be associated with obtaining the container instances of the virtual containers may be determined based on the determined item prices and/or the determined probabilities. A store interface may present offers to the users to purchase the container instances of the virtual containers at the determined container prices. |

Systems and methods for providing media content over an electronic network
A facility for processing a search query is described. The facility identifies one or more items that satisfy the query, at least one of which is a media sequence. For each identified media sequence, the facility identifies an advertising message based upon the contents of the query. In response to the query, the facility returns a search result that indicates the identified items. When one of the identified media sequences is selected in the search result, the selected media sequence is provided in conjunction with the advertising message identified for it. |

Ad collision reduction
An ad collision machine can be configured to evaluate collision queries for possible ad collisions and is associated with an ad datacenter configured to evaluate and respond to bid requests on behalf of a plurality of advertisers. The ad collision machine can comprise a plurality of nodes and a data cache containing a plurality of user ID-campaign ID keys representing recently submitted bids in response to bid requests. Once a selected node receives a collision query, a user ID-campaign ID key is retrieved from the collision query. If the first key is not found in the data cache, it is written to the data cache by the node and the ad collision machine returns that user ID-campaign ID pair as available to be bid on. |

Method and apparatus for guiding service flow
In an implementation, guiding a service flow is described. Historical behavior data of one or more users who use a target service is obtained for the target service. The historical behavior data is analyzed to obtain one or more user features. One or more target users are selected from one or more users who do not use the target service based on the one or more user features. Each target user has at least one of the one or more user features. Service flow guiding information is sent to each target user. The service flow guiding information guides each target user to use the target service. |

User segment identification based on similarity in content consumption
The present disclosure is directed toward systems and methods for identifying user segments. In particular, the systems and methods described herein evaluate user session logs to gather media content consumption history information associated with a plurality of users. Additionally, the systems and methods described herein analyze items of media content to identify keywords, genres, and other attributes, and further represent the items of media content as vectors. The systems and methods follow an algorithm to group items of media content into clusters and, based on the clusters of media content, further group users of media content into user clusters (e.g., user segments). |

Systems and methods for presenting supplemental information related to an advertisement consumed on a different device within a threshold time period of an end of a corresponding advertisement slot
Systems and methods are described for presenting supplemental information to a user that is related to an advertisement consumed by the user that the user found interesting. It may be determined that a user is interested in receiving supplemental information based on the user starting to use a device within a threshold time period from consuming the advertisement on a different device. The threshold time period may be determined based on the length of the advertisement slot including the advertisement (e.g., the threshold time period may be 30 seconds if the length of the advertisement slot is 30 seconds). In response to determining that the user started using the first device within the threshold period of time from the end of the advertisement, supplemental information associated with the advertisement may be presented to the user. |
