Abstract: Embodiments of the present application provide a character recognition method and device. The method includes obtaining a target image to be analyzed which contains a character (S101); inputting the target image into a pre-trained deep neural network to determine a feature map corresponding to a character region of the target image (S102); and performing character recognition on the feature map corresponding to the character region by the deep neural network to obtain the character contained in the target image (S103). The deep neural network is obtained by training with sample images, a result of labeling character regions in the sample images, and characters contained in the sample images. The method can improve the accuracy of character recognition.

Abstract: The present disclosure relates to passive optical network (PON) systems, optical line terminals (OTLs), and optical network units (ONUs). One example PON system includes an OLT and at least two ONUs. The OLT and the ONUs exchange data on one downstream channel and two upstream channels. The OLT sends downstream data to each ONU on the downstream channel, where the downstream data includes an upstream bandwidth grant used to control each ONU to send upstream data. Each ONU receives the downstream data on the downstream channel, and sends the upstream data on a first upstream channel or a second upstream channel based on the upstream bandwidth grant included in the downstream data. The OLT receives, on the first upstream channel and the second upstream channel, the upstream data sent by each ONU, where a registration function is disabled on the first upstream channel, and enabled on the second upstream channel.

Abstract: Systems, apparatuses, and methods for aligning active and idle phases of components in a computing system are disclosed. A computing system includes components that can be forced into an active or idle phase and components that cannot be forced into an active or idle phase. The system implements schemes for aligning the active and idle phases of the components within the system. For example, a timer starts counting when a processor and memory subsystem go from a low power state to an operational state. If the amount of time spent by the processor and memory subsystems in the operational state without transitioning to the low power state exceeds a threshold, the system forces active-to-idle and idle-to-active phase transitions of components in the system in order to cause a realignment of active and idle phases of the various components within the system.

Abstract: The application relates to liposomal nanovesicles comprising porphyrin-lipid conjugates within the liposomal lipid bilayer. Said porphyrin-lipid conjugate comprise porphyrins that are modified with a —CH(R1)—O—R2 group and that chelate a metal ion. Such modifications of the porphyrin allow for ordered assembly in the lipid bilayer of the nanovesicles while resulting in a bathochromic shift in the wavelength of light absorbed by the porphyrin chromophore. These nanovesicles can be used for photothermal therapy, photodynamic therapy, photoacoustic imaging and fluorescence imaging. The application also teaches methods for preparing the porphyrin-lipid conjugates and the nanovesicles.
