A device includes a processor. The processor is configured to determine a hit time for each of a plurality of content items based on at least one of users' history of access to the content items on content distribution clusters in a content distribution network, the users' past ratings of the content items, and social network information associated with the users. The hit time of a content item indicates a number of times that the content item is likely to be accessed by the users. The processor is further configured to compute caching priorities of the content items based on a caching policy of the device and the determined hit times, and initiate a redistribution, over a network, of the plurality of content items over the content distribution clusters of the content distribution network based on the caching priorities.
摘要:
Various embodiments are disclosed for generating multiple output bitrates of a video processing device for encoding video. The method comprises receiving video data comprising a plurality of frames encoding, by a single encoding engine, the received video data to generate a plurality of bitstreams corresponding to different bitrates by sharing such coding decisions as which motion vectors to retrieve, intra-mode prediction, and intra and inter-mode decisions. The method further comprises determining an available network bandwidth for transmitting encoded video and transmitting one or more of the plurality of bitstreams generated by the single encoding engine based on the determined available bandwidth.

Disclosed herein are polypeptides, polynucleotides encoding, cells and organisms comprising novel DNA-binding domains, including TALE DNA-binding domains. Also disclosed are methods of using these novel DNA-binding domains for modulation of gene expression and/or genomic editing of endogenous cellular sequences.
摘要:
A computer-implemented method for tracking one or more objects in a sequence of images includes generating a dictionary based on object locations in a first image included in the sequence of images. One or more object landmark candidates are identified in the sequence of images and a plurality of tracking hypothesis for the object landmark candidates are generated. A first tracking hypothesis is selected from the plurality of tracking hypothesis based on the dictionary.
摘要:
A metal clamp with a plastic sleeve, includes a clamp body made of metal, wherein the plastic sleeve is disposed at the clamp body to locate the clamp body. The plastic sleeve can be classified into an integral plastic sleeve and a split type plastic sleeve. The clamp body is fixed to the plastic sleeve by a circumferential groove on the plastic sleeve. The present invention has the advantage as follows. A shaking of the metal clamp in construction is avoided, the plastic pipe and the pipe fitting is able to achieve firm connection. In addition, fittings between the inner diameter on both ends of the plastic sleeve and the plastic pipe is capable of keeping a relative position among the metal clamp, the plastic pipe and the pipe fitting.

Systems, methods, and apparatuses including computer program products for universal language input are provided. In one implementation, a method is provided. The method includes using a first application or operating system component to detect user input to an application interface of a second application. The method also includes, as input is detected in the application interface, automatically using the first application to provide one or more translations of the input including, sending the input to a translation model, receiving translated input from the translation model, and sending the translated input to the application interface of the second application.
摘要:
A trench gate MOSFET device has a drain region, a drift region, a trench gate having a gate electrode and a poly-silicon region, a super junction pillar juxtaposing the trench gate, a body region and a source region. By the interaction among the trench gate, the drift region and the super junction pillar, the break down voltage of the trench gate MOSFET device may be relatively high while the on-state resistance of the trench gate MOSFET device may be maintained relatively small.
摘要:
There is provided a computer-implemented method of performing sentiment analysis. An exemplary method comprises identifying one or more sentences in a microblog. The microblog comprises an entity. The method further includes identifying one or more opinion words in the sentences based on an opinion lexicon. Additionally, the method includes determining, for each of the sentences, an opinion value for the entity. The opinion value is determined based on an opinion value for each of the opinion words in an opinion lexicon.
摘要:
A projection display device includes a first display panel (23a), a second display panel (23b), a PBS (Polarization Beam Splitter) (22) with a first surface (22a) and a second surface (22b) opposite each other, a light recycling device (25a, 25b and 23b), and a projection lens (24). The PBS (22) transmits a first type parallel polarized light and reflects a second type parallel polarized light. The light recycling device (25a, 25b and 23b) transforms the first type parallel polarized light transmitted by the PBS (22) into the second type parallel polarized light which carries a second image information, then reversely transmits the second type parallel polarized light to the second surface (22b) of the PBS (22).The projection display device improves the light utilization efficiency and can be used for 3D display.
