Abstract: The present disclosure relates to the field of preparation of compound semiconductor nanomaterials, and in particular to a method for in-situ modification of mercury quantum dots in a traditional thermal injection process. It is characterized in that, in the traditional thermal injection process for synthesis of HgTe quantum dots, after a certain reaction time, a low boiling point polar solvent that is incompatible with a reaction solvent is rapidly injected, so that an interfacial separation of two liquid phases occurs in a mixed reaction, and then a selective crystal oriented surface modification is conducted on surfaces of mercury quantum dots.

Abstract: This invention relates to a surfactant composition, production and use thereof in tertiary oil recovery. The present surfactant composition comprises a cationic surfactant and an anionic-nonionic surfactant, and exhibits significantly improved interfacial activity and stability as compared with the prior art. With the present surfactant composition, a flooding fluid composition for tertiary oil recovery with improved oil displacement efficiency and oil washing capability as compared with the prior art could be produced.

Abstract: A UE in cellular communication system may be equipped with multiple User Services Identity Modules (USIMs) to support multiple service subscriptions. The UE having multiple service subscriptions may obtain services from one or more wireless networks with each of the subscriptions. When the UE having multiple service subscriptions needs to make an emergency call, the UE may identify and determine a service subscription to make the emergency call, so that the emergency call can be successfully made. The UE may be implemented with a communication processor (modem) and an application processor (AP). Some information that is useful to identify a service subscription more suitable for the emergency call may be available only at the communication processor. Enhanced techniques for identifying and determining a service subscription to make the emergency call from the multiple service subscriptions through interaction between the communication processor and the application processor are disclosed.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect, while operating in an out-of-service (OOS) mode associated with a first network, that a second network satisfies one or more switching criteria. The UE may increase a time duration associated with a periodic network acquisition scan associated with the first network based at least in part on detecting that the second network satisfies the one or more switching criteria. The UE may switch, while operating in the OOS mode, from using the first network for connectivity to using the second network for connectivity based at least in part on detecting that the second network satisfies the one or more switching criteria. Numerous other aspects are described.

Abstract: Techniques for weather information extraction using image data are described herein. In accordance with the present disclosure, economical weather data collection devices may be installed in any places on the earth, and form a dense network of weather data collection devices. Preferably, these weather data collection devices include image capture components that may capture series of sequential images over time (i.e., image streams) from any particular locations. The disclosed techniques include extracting a sky portion from a series of time-sequenced images. The extracted sky portion may be used for determining cloud coverage, a sun track, and so on, thereby enabling to provide accurate weather forecast as well as other weather data mining abilities.
