  • Publication number: 20160205154
    Abstract: In one embodiment, a method includes identifying a first device as being located at a first physical location associated with a meeting, and determining when the first device is no longer located at the first physical location during the meeting. When it is determined that the first device is no longer located at the first physical location during the meeting, the method also includes determining whether to provide a meeting link to the first device, the meeting link being arranged to allow the first device to join the meeting. Finally, the method includes providing the meeting link to the first device if it is determined that the meeting link is to be provided to the first device.

  • Publication number: 20160102306
    Abstract: Compositions and methods are provided for enzymes with altered properties that involve a systematic approach to mutagenesis and a screening assay that permits selection of the desired proteins. Embodiments of the method are particularly suited for modifying specific properties of restriction endonucleases such as star activity. The compositions includes restriction endonucleases with reduced star activity as defined by an overall fidelity index improvement factor.

  • Publication number: 20150058748
    Abstract: In a sharing session between a presenter and several attendees, the presenter can share any type of document quickly and without substantial prior preparation. The presenter's device identifies an active document-sharing window within the desktop sharing environment, and detects if there is a shared document in the active window. The presenter's device creates a framework for any detected shared document that is transmitted to each of the attendee devices. The framework contains information about the pages in the shared document, such that an attendee device can request a specific page in the shared document. At least the first page of the shared document is rendered to a page image and transmitted to the attendee devices. Upon request from an attendee device, page images of any of the remaining pages may be sent to the attendee device, allowing each attendee to view a different page than the presenter.
