20130075702 | Tunable Hot-Electron Transfer Within a Nanostructure - Provided are multimaterial devices, such as coaxial nanowires, that effect hot photoexcited electron transfer across the interface of the materials. Modulation of the transfer rates, manifested as a large tunability of the voltage onset of negative differential resistance and of voltage-current phase, may be effected by modulating electrostatic gating, incident photon energy, and the incident photon intensity. Dynamic manipulation of this transfer rate permits the introduction and control of an adjustable phase delay within a device element. | 03-28-2013 |

20140245115 | SYSTEMS AND METHODS FOR AUTOMATED CONTENT GENERATION - A computerized method for automatically generating display content includes receiving a uniform resource locator, wherein the uniform resource locator specifies a landing resource and extracting visual information from the landing resource, wherein the visual information defines one or more images, texts, and colors displayed on the landing resource. The method further includes selecting one or more images, one or more text snippets, and one or more colors based on the visual information extracted from the landing resource, generating a layout for a content item based on one or more of the selected images or selected text snippets, and assembling the content item by applying the selected images, the selected text snippets, and the selected colors to the generated layout. | 08-28-2014 |
20150206169 | SYSTEMS AND METHODS FOR EXTRACTING AND GENERATING IMAGES FOR DISPLAY CONTENT - Systems and methods for automatically generating display content are provided. A uniform resource locator identifying a landing resource is received from a third-party content provider. One or more images are extracted from the landing resource. The extracted images are analyzed to detect the visual content and semantic content thereof. The extracted images are scored based on at least one of the detected visual content and the detected semantic content. The highest-scoring image is selected from a set of images that includes the images extracted from the landing resource. A third-party content item that includes the selected image is generated and served to a user device. The third-party content item is configured to direct the user device to the landing resource. | 07-23-2015 |

20150286742 | SYSTEMS AND METHODS FOR OPTIMIZING CONTENT LAYOUT USING BEHAVIOR METRICS - Systems and methods for optimizing content layout using behavior metrics are provided. Behavioral data is collected for a content item presented on a client device. The behavioral data indicates various locations within a display area of the content item at which a user action (e.g., clicking) occurs. The behavioral data is used to assign weights to various components of a layout scheme for the content item. A user action that occurs within an area of the content item associated with a particular component of the layout scheme contributes to the weight of the corresponding component. The weights associated with each component of the layout scheme are used to optimize the layout for the content item. Components with greater assigned weights are highlighted or emphasized. The display sizes of components in the optimized layout scheme may correspond to the weights associated with the components. | 10-08-2015 |
