20140283091 | DIFFERENTIALLY PRIVATE LINEAR QUERIES ON HISTOGRAMS - The privacy of linear queries on histograms is protected. A database containing private data is queried. Base decomposition is performed to recursively compute an orthonormal basis for the database space. Using correlated (or Gaussian) noise and/or least squares estimation, an answer having differential privacy is generated and provided in response to the query. In some implementations, the differential privacy is ε-differential privacy (pure differential privacy) or is (ε,δ)-differential privacy (i.e., approximate differential privacy). In some implementations, the data in the database may be dense. Such implementations may use correlated noise without using least squares estimation. In other implementations, the data in the database may be sparse. Such implementations may use least squares estimation with or without using correlated noise. | 09-18-2014 |

20130212690 | PRIVATE DECAYED SUM ESTIMATION UNDER CONTINUAL OBSERVATION - Described herein is a method and system for providing privacy guarantees with an improved privacy-accuracy trade-off. Dynamic data can be accessed from a database. A sum model is selected from window sum, exponential decay sum, and polynomial decay sum. An algorithm is initiated that produces polylogarithmic bounded error in the range of a sum function associated with the selected sum model and independent of time steps. The data can be assembled in a dyadic tree structure. A non-linearity component can be added to nodes of the dyadic tree structure. For example, this can be a noise components or a weight applied to the update. This can be done, for example, to different nodes differently. Differential private estimators can be constructed for fixed steps of time. The differential private estimators can be applied to a query means or filtering system to enhance privacy protection from potential adversaries. | 08-15-2013 |

20080317763 | Regulation of Metalloprotease Cleavage of Cell Surface Proteins - Elucidation of the crystal structure of an ADAM10 substrate-recognition and proteinase-positioning module comprising the protein cysteine-rich and disintegrin domains, and detailed functional analysis revealed that an acidic pocket within the cysteine-rich domain forms a substrate-recognition site. The binding of this pocket to receptor/ligand complexes facilitates effective ligand cleavage, which is prevented when critical residues within the pocket are changed. This provides use of the surface pocket within the extracellular domain of ADAM10, and the corresponding structure in related proteases such as ADAM17, as a target for structure-based computational and high-throughput screens for small-molecule substrate-specific inhibitors or monoclonal antibodies that inhibit ADAM protease cleavage of ephrins and other ADAM10 or ADAM17 substrates. These inhibitors will be useful in therapeutic intervention of tumour development, invasion and metastasis and other diseases which involve the activity of the ADAM10 and ADAM17 proteases, such as inflammation, cardio-vascular disease, arthritis and other auto-immune diseases. | 12-25-2008 |

20130167156 | WEB PAGE TO TOOLBAR COMMUNICATION - A web page may initiate communication with a browser toolbar. In one example, the web page contains an invisible iframe, and code that causes the iframe to load a specific Uniform Resource Locator (“URL”). When the iframe loads that URL, it generates an onload event. The toolbar may subscribe to the iframe's onload event, and may contain a handler for that event. When the page wants to send a message to the toolbar, the page adds the message to a URL and then executes the code that causes the iframe to load that URL, thereby generating an onload event. The handler in the toolbar receives the onload event, and extracts the message from the URL. The handler may then execute additional code to perform an action in response to the message. | 06-27-2013 |
