Obtained expanded graphite can realize 50-1500 times of volume expansion, and an sp2 hybridization structure of a graphene sheet layer is basically not damaged; and the obtained expanded graphite can be widely applied to the fields of energy storage, heat management, photoelectronic devices, solar cells, anti-corrosive materials, various composite materials, and the like.

Abstract: An online system maintains a plurality of content items. The online system selects and provides content items to users of the online system in response to impression opportunities to provide content items to users. A plurality of segments of the impression opportunities are determined. Each segment categorizes the impression opportunities. A relationship between a value metric and computing resources used in the selection process are determined for each segment. Each relationship provides a rate of increase of the value metric given an increase in computing resources used. An allocation of computing resources used per impression opportunity for each of segment is determined based on the rates. A plurality of impression opportunities are identified. In response, one or more content items are selected for each impression opportunity using computing resources according to the determined allocation for the segment to which each impression opportunity belongs.

Abstract: A communication receiver receives a signal sample stream of an orthogonal frequency division multiplexing (OFDM) signal, splits the signal sample stream into blocks, where each block corresponds to a symbol or a gap of the OFDM signal, determines an estimate of a periodic noise in the OFDM signal by averaging signal samples over a number of blocks, generates a noise-suppressed signal by subtracting the estimate of the periodic noise from the signal sample stream, and performs further receiver-side processing on the noise-suppressed signal.

Abstract: Content provider systems publish content via content publishing platforms. An online system is associated with multiple content publishing platforms. Each content publishing platform is associated with policies that determine whether a content item is acceptable for publishing via the content publishing platform. For example, the policy may specify dimensions of a media object of the content item, keywords that are unacceptable for publishing via the content publishing platform, and so on. The online system receives requests from content provider systems to publish content via a particular content publishing platform. The online system determines whether the content item is suitable for publishing via one or more other content publishing platforms. The online system determines whether the content provider system approves publishing content via any of the identified content publishing platforms.

Abstract: An online system receives advertisements from advertisers and reviews the advertisement for compliance with policies enforced by the online system. The online system computes scores for each advertisement based on an expected revenue from presenting various advertisement and/or interactions with various advertisements and orders advertisements for review based on their scores. If a predicted time for the online system to review an advertisement is greater than a threshold amount of time, the online system allows the online system to be evaluated for presentation to users. As the online system receives interactions with the advertisement, the online system may modify the score for the advertisement and modify the order of the advertisement for review based on the modified score.
