Abstract: Generating an interactive discovery feed of place of interest items (POIs) relevant to a user is provided. A relevant POI discovery feed system curates a collection of narratives about various POIs from multiple sources and generates a plurality of POI content feed items including content items (e.g., photos, maps, links to additional information or related POIs) extracted from the collection of narratives. The system determines a set of POIs relevant to a user based on user-selected topics of interest and user preferences inferred from signals generated from user interactions with the system, and generates a discovery feed of POI content feed items associated with the set of relevant POIs for display to the user. In some examples, the items are presented in a card-based UI. Users are enabled to easily discover new places, view photos, and learn more about POIs in a consistent presentation of POI-related content feed items.

Abstract: The invention relates to orthodontic appliances that simulate the center of resistance in orthodontic treatment. The orthodontic appliance includes at least one bonding pad for attaching said appliance to a corresponding lingual side of a tooth and a netted structure extending in a mesial-distal direction substantially below the at least one bonding pad. The netted structure engages or passes components for delivering force in orthodontic treatment. With aid of the force delivering components engaged or passed in the netted structure, a dentist or a clinician can advantageously simulate the center of resistance in a dentition or a tooth in orthodontic treatment for space closure and/or distalization.

Abstract: A power source converts &agr;-particle energy to electricity for use in electrical systems. Liquid gallium or other liquid medium is subjected to &agr;-particle emissions. Electrons are freed by collision from neutral gallium atoms to provide gallium ions. The electrons migrate to a cathode while the gallium ions migrate to an anode. A current and/or voltage difference then arises between the cathode and anode because of the work function difference of the cathode and anode. Gallium atoms are regenerated by the receiving of electrons from the anode enabling the generation of additional electrons from additional &agr;-particle collisions.
