Abstract: Provided are catechol nanoparticles, catechol protein nanoparticles, and a preparation method and use thereof. The method includes: adding a tannin compound-containing natural herb medicine into water to obtain a mixture, and subjecting the mixture to heating reflux extraction to obtain a herb medicine extract and subjecting the herb medicine extract to fractionation to obtain the catechol nanoparticles.

Abstract: Disclosed is an integrated diaphragm pump, comprising a first stop plate (1), a foaming member (2), a valve plate (5), a diaphragm (7), and a motor (10), wherein the foaming member (2) comprises a gas-liquid mixing tank (21) and a foaming cavity, and an outlet of the gas-liquid mixing tank (21) is in communication with the foaming cavity for mixing a gas and a liquid and foaming same by means of the foaming cavity. The integrated diaphragm pump has the advantages of being high in integration and small in size.

Abstract: A computer-implemented method for preventing the occurrence of performance tickets in a computing system comprising a plurality of virtual machines hosted by a host computing system. The method comprising the steps of: monitoring a resource usage parameter associated with the workload of a virtual machine in order to obtain historic resource usage information; determining information regarding certain dependencies within the historic resource usage information; selecting partial information from the historic resource usage information based on said determined information regarding certain dependencies; estimating the future workload of the virtual machines based on said selected partial information; and resizing the computational resources of one or more virtual machines based on the estimated future workload such that a usage threshold of a computational resource is below a given threshold in order to avoid the generation of a performance ticket.

Abstract: A system and method for tire management is provided. The method includes: generating, by an activator, an activation signal; transmitting, by the activator, the activation signal to a sensor; receiving, by the sensor, the activation signal from the activator; generating, by the sensor, tire information relating to a tire on which the sensor is installed, if the sensor receives the activation signal; transmitting, by the sensor, the tire information to a computing device; receiving, by the computing device, the tire information from the sensor; and generating, by the computing device, an event based on the tire information.
