  • Publication number: 20180025021
    Abstract: Determination logic for a cloud content states framework is described herein. In implementations, a framework is configured to perform operations for management of cloud content files at the computing device on behalf of cloud storage providers. Determination logic for the framework is utilized to make state determinations in dependence upon a defined set of file sync properties. The framework operates to make assessments of the file sync properties and set states for files in accordance with the assessments. In implementations, file sync properties are related to corresponding states through a mapping data structure that maps file sync property values to different states and enables look-ups of states based on property values. The framework utilizes and references the mapping data structure to match file sync properties identified for cloud content files to corresponding states and then set states for the cloud content files accordingly.

  • Publication number: 20170269029
    Abstract: There is provided a method for sensing the translocation of a molecule through a nanopore. In the method, there is directed to an inlet of a nanopore a molecule that is disposed in a first ionic solution of a first ionic concentration. The molecule is caused to translocate through the nanopore from the inlet of the nanopore to an outlet of the nanopore and into a second ionic solution of a second ionic concentration that is different than the first ionic concentration. An electrical potential, local to that ionic solution, of the first and second ionic solutions, which has a lower ionic concentration, is measured while the molecule is caused to translocate through the nanopore.

  • Patent number: 9638717
    Abstract: The present invention generally relates to nanoscale wires for use in sensors and other applications. In various embodiments, a probe comprising a nanotube (or other nanoscale wire) is provided that can be directly inserted into a cell to determine a property of the cell, e.g., an electrical property. In some cases, only the tip of the nanoscale wire is inserted into the cell; this tip may be very small relative to the cell, allowing for very precise study. In some aspects, the tip of the probe is held by a holding member positioned on a substrate, e.g., at an angle, which makes it easier for the probe to be inserted into the cell. The nanoscale wire may also be connected to electrodes and/or form part of a transistor, such that a property of the nanoscale wire, and thus of the cell, may be determined. Such probes may also be useful for studying other samples besides cells.

  • Patent number: 9595685
    Abstract: The present invention generally relates to nanotechnology, including field effect transistors and other devices used as sensors (for example, for electrophysiological studies), nanotube structures, and applications. Certain aspects of the present invention are generally directed to transistors such as field effect transistors, and other similar devices. In one set of embodiments, a field effect transistor is used where a nanoscale wire, for example, a silicon nanowire, acts as a transistor channel connecting a source electrode to a drain electrode. In some cases, a portion of the transistor channel is exposed to an environment that is to be determined, for example, the interior or cytosol of a cell. A nanotube or other suitable fluidic channel may be extended from the transistor channel into a suitable environment, such as a contained environment within a cell, so that the environment is in electrical communication with the transistor channel via the fluidic channel.
