摘要:
The present invention provides self-assembling, finite nucleic acid tiling arrays, and methods for their synthesis and use, which overcome a major hurdle in self-assembled DNA nanostructures, and therefore have numerous potential applications for nanofabrication of complex structures and useful devices, as further disclosed herein.

An atomic force microscope and a method for detecting interactions between a probe and at least one sensed agent on a scanned surface is provided. The microscope has a scanning probe with a tip that is sensitive to a property of said scanned surface; a nucleic acid aptamer tethered to the tip of the probe; and a device for simultaneously recording the displacement of said probe tip as a function of time, topographic images, and the spatial location of interactions between said probe and the at least one sensed agent on said surface.

A network update interface is presented to a user on a network to display network updates from other users of a mutual social-networking site. The network updates shared by the other users are gathered in a stream and supplied to a facet-filtering system including a network update interface. The user controls the display of certain network update items according to facet-filter characteristics enabled in facet-filter selection panels in the network update interface. The facet-filter characteristics are used by a facet filter to select certain network updates for display to the user in the network update interface. Trending links to further articles with content corresponding to the facet-filter characteristics are displayed to the user according to greatest popularity among the other users. Links to the profiles of the users sharing the articles are also provided in the network update interface.
摘要:
Architecture that provides synchronization of delegation permissions between discrete delegation models. For example, the synchronization of the delegation permissions (of a delegator and delegatee) can be performed between a delegation component of a scheduling system and a delegation component of a conferencing system such that the delegatee not only accesses the scheduling system on behalf of the delegator but also the conferencing system on behalf of the delegator. A synchronization component synchronizes the delegation permissions between the server systems (delegation components). Once synchronized, the delegatee administers the communications session, based on on-behalf-of information is validated, the delegatee can then establish the communications session.

Described are CdTe/CdS/ZnS core/shell/shell nanocrystals, methods for making the same, and their use in biomedical and photonic applications, such as sensors for analytes in cells and preparation of field effect transistors. In particular, the disclosure provides a nanocrystal having a CdTe core, a CdS coating over the core, and a ZnS core over the CdS coating, where the nanocrystal has a photoluminescence maximum between about 650 nm and 900 nm.
