Abstract: A dental appliance includes a base and a coating layer. The base includes a 3D shell-shaped structure configured according to a treatment plan, polymeric materials, and unbound small molecules. The ratio of the weight of the unbound small molecules to the weight of the base is greater than a first predetermined value for improving ductility and toughness of the base. The coating layer is formed over an inner surface and an outer surface of the base. The coating layer surrounds the base and blocks movements of the unbound small molecules.

Abstract: Provided are a mobile phone-based biological testing method and apparatus. The method includes: selecting N kinds of quantum dots of specific wavelengths to label N to-be-tested biomarkers in a sample, where N is 1, 2 or 3; exciting to-be-tested biomarker-quantum dot compounds using excitation light; photographing the above excited compounds for multiple times, so as to obtain a first original image file in a RAW format with a 16-bit depth; photographing unlabeled quantum dots to obtain a second original image file in a RAW format with a 16-bit depth; calculating a matrix of transition coefficients of fluorescence intensities of the quantum dots received by channels in the second original image file; calculating a fluorescence intensity of each of the to-be-tested biomarker-quantum dot compounds in the first original image file; and obtaining a concentration of each of the to-be-tested biomarkers according to the fluorescence intensity, so as to complete biological testing.

Abstract: A system for package pre-fetching for a remote program installation includes a service node having a processor, a computing node type database, and a cache, the service node being configured to receive at least one package request for a package required for an installation of an operating system and at least one peripheral application thereof from a computing node, and determine a package request sequence by which the computing node issues the at least one package request according to a type of the computing node. In another embodiment, a method includes receiving a package request from a computing node, and determining a package request sequence by which the computing node issues at least one package request according to a type of the computing node, so as to pre-read a subsequent package into a cache before the computing node issues a request for the subsequent package.

Abstract: A system for a package pre-fetching for a remote program installation. The system includes a cache and a service program unit. The service program unit receives a request for a package required for an installation of an operating system and at least one peripheral application thereof from a computing node. The service program unit determines a package request sequence by which the computer node issues one or more package requests according to a type of the computing node, so as to pre-read a subsequent package from an external storage device into the cache before the computing node issues a request for the subsequent package.
