Abstract: A rapid, ultrasensitive and inexpensive nanoplasmon-enhanced scattering (nPES) assay that directly quantifies tumor-derived EVs from as little as 1 ?L of plasma is described herein. This assay uses binding of gold nanospheres and nanorods with EV- and tumor-derived EV-specificities to produce a local plasmon effect that enhances tumor-derived EV detection sensitivity and specificity. This nPES approach is also a non-invasive method for assessing pancreatic cancer stage and treatment response that can be easily refined for clinical use, and is readily adapted for diagnosis and monitoring of other conditions with disease-specific EV proteins.

Abstract: The present application relates to a temperature detection circuit and method, an electronic device, and a computer-readable storage medium. The temperature detection circuit includes: a temperature detection module, configured to charge a charging module based on a detected temperature; a timing module, configured to detect the voltage of the charging module to determine a charging rate of the temperature detection module, generate a first time signal corresponding to the charging rate, and send the first time signal to the processing module; and a processing module, configured to determine a target temperature value through the first time signal. The temperature detection module is configured to charge the charging module based on the detected temperature, so that the charging rate can quickly reflect the detected temperature, which ensures the rate of temperature detection. Meanwhile, the charging rate can accurately match the target temperature value corresponding to the current temperature.

Abstract: A rapid, ultrasensitive and inexpensive nanoplasmon-enhanced scattering (nPES) assay that directly quantifies tumor-derived EVs from as little as 1 ?{umlaut over ({acute over (?)})}, of plasma is described herein. This assay uses binding of gold nanospheres and nanorods with EV- and tumor-derived EV-specificities to produce a local plasmon effect that enhances tumor-derived EV detection sensitivity and specificity.

Abstract: A method for evaluating brittleness of a deep shale reservoir and a computer readable storage medium. The method includes determining a Rickman brittleness index of the deep shale reservoir and determining an effective pressure of the deep shale reservoir according to a pore pressure and an overlying formation pressure of the deep shale reservoir. The Rickman brittleness index is adjusted to obtain the brittleness index of the deep shale reservoir according to an exponential relationship of the brittleness index with the effective pressure of the deep shale reservoir. Inherent properties, such as rock brittle mineral content and the like, are better indicated by the Rickamn brittleness index, and then the brittleness index of the deep shale reservoir is obtained by utilizing the exponential relationship of the brittleness index with the effective pressure of the deep shale reservoir, to realize reasonable evaluation for the brittleness of the deep shale reservoir.

Abstract: Aspects of the present disclosure relate to systems and methods for creating compliance boundaries. In one example, compliance boundaries may be implemented via a compliance tool. Data associated with a tenant may be segregated using a plurality of layers defining one or more compliance boundaries. In response to an action initiated by a compliance administrator using the compliance tool for accessing the data, it may be determined which data is within the one or more compliance boundaries associated with the compliance administrator. Access to the data determined to be within the one or more compliance boundaries associated with the compliance administrator may be authorized.

The fins are spirally wound about the refrigeration pipe and integrally formed by stamping a strip-shaped sheet material, at least including first heat-absorbing and heat-radiating bodies and second heat-absorbing and heat-radiating bodies. Broken lines are arranged between adjacent heat-absorbing and heat-radiating bodies, and each heat-absorbing and heat-radiating body forms a wavy structure. Relative wave crests and wave troughs are formed at each broken line between the adjacent heat-absorbing and heat-radiating bodies, wherein the crests and troughs form a honeycomb structure together. The wavy edges of the first heat-absorbing and heat-radiating bodies make contact with the outer wall of the refrigeration pipe at equal screw pitches.
