    摘要: The present invention provides methods for enhancing the efficiency of cell electroporation using dielectrophoresis-assisted cell localization and uses thereof in a microfluidic biochip system. Cells are first subject to dielectrophoresis and localized to regions where the electric field intensity is high enough to render cells electroporated. The invention enhances the efficiency of in situ cell electroporation on a traditional microfluidic biochip.

    摘要: A slow release apparatus for slowly releasing a compound in a nasal passage. The apparatus comprises a connection mechanism, two expansion mechanisms, and two release mechanisms; two ends of the connection mechanism are respectively integrally or detachably connected to the two expansion mechanisms that are symmetrically arranged in nasal passages at two sides; and the two release mechanisms are symmetrically arranged, and each release mechanism is correspondingly provided in one of the expansion mechanisms. The slow release apparatus is convenient to carry, and capable of slowly releasing a compound in the nasal passage and synchronously expanding the nasal passage to ensure smooth breathing, while considering functionality, practicability and comfort.

    摘要: A method of moving a string assembly within a wellbore is disclosed. In some embodiments, the method comprises moving the string assembly within the wellbore; obtaining surface data regarding at least one parameter associated with moving the string assembly within the wellbore over a range of depths; modeling the at least one parameter over the range of depths for a plurality of assumed friction factors to obtain modeled data for each assumed friction factor; calculating a derivative of the surface data over the range of depths; calculating a derivative of the modeled data over the range of depths; comparing the derivative of the surface data to the derivative of the modeled data; determining one or more local friction factors for the range of depths based on the comparison; and adjusting at least one string assembly operating parameter based on the one or more local friction factors.

    摘要: Systems and methods for characterizing a spatial frequency of interface regions within a subterranean formation. A first method may include drilling a wellbore with a drilling assembly and measuring a downhole parameter during the drilling. The downhole parameter may be indicative of a lithology of a portion of the subterranean formation that is proximal to the drilling assembly. The first method also may include calculating an information entropy of the downhole parameter and characterizing the spatial frequency of the interface regions based upon the information entropy. A second method may include calculating the information entropy as a function of distance within a first wellbore and characterizing the spatial frequency of the interface regions. The second method also may include drilling a second wellbore within the subterranean formation and regulating the drilling based upon the spatial frequency of the interface regions. The systems include systems that perform the methods.
