摘要： Disclosed is an epitaxial substrate with a 2D material interposer on a surface of a polycrystalline substrate. The ultra-thin 2D material interposer is grown by van der Waals epitaxy. The lattice constant of a surface layer of the ultra-thin 2D material interposer and the coefficient of thermal expansion of the substrate base are highly fit with those of AlGaN or GaN. The ultra-thin 2D material interposer is of a single-layer structure or a composite-layer structure. An AlGaN or GaN single crystalline epitaxial layer is grown on the ultra-thin 2D material interposer by virtue of the van der Waals epitaxy. Therefore, the large-size substrate may be manufactured with far lower costs than related single crystal wafers.

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.
