Abstract: A mine clearing system and method remotely deploys line charge from a remotely controlled two-wheeled vehicle. The wheels are connected together via a central hub shaft. Individual battery operated hub motors on each wheel communicate with a central controller and receiver mounted inside the hub shaft. The power source for the motors is contained within the hub shaft, with a battery recharge port located on the hub shaft. The line charge is wrapped around the central hub shaft. An operator uses a remote control console in communication with the receiver and central controller in the hub shaft to independently control each wheel of the vehicle. A camera can hang from a hub shaft bearing on the outside of one wheel so as to be gravitationally stabilized during vehicle movement. The camera can broadcast signals to a display at the remote control console.

Abstract: A seed cluster comprising a group of users who share a particular attribute and/or affiliation is determined by a social networking system. For each user of the seed cluster, other users and/or entities connected to the user in the social networking system are retrieved. For each retrieved other user or entity, the social networking system may determine whether the other user or entity exhibits the attribute or affiliation based on a random walk algorithm. A resulting targeting cluster of users and/or entities may be used for targeting advertisements targeting to members. A social networking system may also infer an affiliation for a user based on the user's interaction with a page, application, or entity where other users who interacted with the same page, application, or entity have the same affiliation.

Abstract: A social networking system user's interaction with a brand page may be tailored to match the user's interests. Content providers or page administrators of a brand page associate keywords with content posted to the brand page. A keyword may define a characteristic of a social networking system user to receive the content or may describe a characteristic of the content. The keywords are compared to a user profile of a user requesting the brand page and content posted to the brand page is selected for presentation to the user based on the user profile and the keywords. For example, content is presented to a user having a characteristic defined by criteria keyword. The selected content posted to the brand page is presented to the user requesting the brand page.

Abstract: Users of a social networking system perform actions on various objects maintained by the social networking system. Some of these actions may indicate that the user has a negative sentiment for an object. To make use of this negative sentiment when providing content to the user, when the social networking system determines a user performs an action on an object, the social networking system identifies topics associated with the object and associates the negative sentiment with one or more of the topics. This association between one or more topics and negative sentiment may be used to decrease the likelihood that the social networking system presents content associated with a topic that is associated with a negative sentiment of the user.

Abstract: Content posted to a brand page is associated with one or more tags defined by an entity associated with the brand page. Tags associated with content with which the user interacts are identified. As users of a social networking system interact with the content, the tags allow identification of user interests based on interaction with content items. Interactions with the tagged content allow the entity to use the tags to infer content in which different users have an interest. Because the tags are defined by the entity, distribution lists of users interested in content, such as content associated with business segments, may be created by the entity. The entity may also correlate user interests to aspects of user profiles, thereby developing an understanding of its consumers.

Abstract: An entity having a brand page maintained by a social networking system defines a sequence of content items associated with a brand page is determined. Different content items in the sequence include different information that is dependent on interaction between a user and the sequence. For example, content items in the sequence provide increasingly more detailed or complex information when progressing from the first content item to the last content item in the sequence. When a viewing user of a social networking system interacts with the brand page, prior interactions with the sequence by the viewing user are used to classify the viewing user and to select a content item from the sequence that is communicated to the viewing user.

Abstract: The present disclosure describes environmentally responsive polypeptides capable of displaying stimuli-triggered conformational changes in a reversible or irreversible manner that may be accompanied by aggregation. Polypeptides include a number of repeated motifs and may be elastomeric or non-elastomeric. The polypeptides may be used to deliver therapeutics to a biological site and to develop bioactive polypeptides that are environmentally responsive.

Abstract: A system for reducing the operational efficiency of a watercraft's propulsion system includes a self-propelled and variable-speed unmanned underwater vehicle (UUV) that has at least one homing device adapted to direct the UUV towards an origin of a targeted watercraft's propulsion wake. At least one rod is coupled to a forward end of the UUV and extends forward therefrom at least when the UUV is in proximity to the origin of the targeted watercraft's propulsion wake. At this point, the UUV is directed and accelerated to drive the rod into the targeted watercraft's propulsor.

Abstract: A story describing an activity performed by an interacting user is distributed to viewing users according to the influencer scores for the viewing users. Each influencer score can be calculated based at least in part on the influence of a viewing user on those users connected to the viewing user, and on the influencer scores for the users connected to the viewing user. Based on the determined influencer scores, at least one of the viewing users can be provided with the story describing the activity performed by the interacting user.

Abstract: A structure, e.g. a pop-up tent, usable in extremes of temperature, wind, and aridity. One side of the structure's fabric reflects heat, and the other absorbs heat. The structure is reversible, so that, depending which side is outside and which inside, the structure either rejects or absorbs ambient heat, making the structure cooler in hot environments, and warmer in cool environments. The structure can have a detachable base with a hollow chamber in which one can put thermally insulating fluid (e.g. water) to add further comfort, which also provides additional physical and thermal stability to the structure. An optional moisture collector is disposable inside to collect condensate for recycling, and the fabric of the structure can be hydrophobic to direct other condensate to the base and away from occupants.

Means for altering the trajectory of a projectile entering said plenum are dispersed within the plenum.

Abstract: A method and system for neutralizing mines has a vehicle carrying fluid connected to a pump and cavitation pressure vessel that creates high pressure fluid. An actuator valve modifies the flow characteristics of the high pressure fluid to be pulsating at selectively different frequencies, pressures, and flow rate. Nozzles on the vehicle jet high pressure fluid therethrough and a framework on the vehicle orients the nozzles to direct the jetted flow of high pressure fluid downward and into ground under a roadway. An abrasive and/or explosive can be added to the high pressure fluid before it reaches the nozzles. The jetted flow from the nozzles can displace ground and exert pressure to detonate and cut mines and neutralize them on and under the roadway. Cavitation can be created in the jetted flow to increase the dynamic force of the jetted flow.
