Abstract: The present utility model provides a chip-on-film packaging structure, comprising a chip-on-film package body and a heat dissipating sheet configured for covering the chip-on-film package body and dissipating heat of a chip contained in the chip-on-film package body, wherein the heat dissipating sheet comprises a main attachment area and a bulge suppression portion, the main attachment area is covered and bonded to an upper surface of the chip, the bulge suppression portion is disposed at an outer periphery of the main attachment area to prevent the heat dissipating sheet at the four corners of the chip from bulging. The present utility model can smooth the bulge at the corner of the heat dissipating sheet and make the heat dissipating sheet stick to the four side surfaces of the chip more tightly, thereby improving bonding reliability and enhancing heat dissipation efficiency.

Abstract: The invention relates to a contribution incentive-based blockchain collaboration method and system, which is characterized in, comprising: 1) applying from an ordinary node to a qualification assessment node for registered qualification; 2) dividing a task into a number of subject tasks and creating corresponding subject task ledgers respectively, and creating a number of sub-tasks corresponding to the subject task in each of the subject task ledgers; 3) applying from the ordinary node to the qualification assessment node for receiving the sub-tasks; 4) by the qualification assessment node, auditing all sub-tasks which are applied for reception by the ordinary node; 5) submitting completed sub-tasks from the ordinary node to a task quality audit node; 6) by the task quality audit node, calculating contribution incentives and qualification credits for the sub-tasks completed by the ordinary node; 7) by the task quality audit node, traversing through each subject task ledger respectively, for finding out a bloc

Abstract: The present disclosure belongs to the technical field of intelligent kin recognition, and relates to a new biological kin recognition method and system based on unsupervised clustering of mRNA bases, including the following steps: step S1, extracting base codons from an mRNA chain, and re-encoding the base codons according to encoding rules; step S2, converting a re-encoded base chain into a document capable of being identified by a model; step S3, inputting the document into the model to vectorize base texts, and clustering vectorized base texts; and step S4, visualizing clustering results to obtain a biological kin recognition result. The present disclosure does not need to artificially annotate the data, saves labor costs, and avoids effects of artificial factors on taxonomical results, featuring simple use, efficient program run, and fast speed.

Abstract: The present invention relates to a base material for high temperature alloy and a process for manufacturing the same. The base material includes following components (by weight): 10-45% Cr, 0.5-12% Nb, 0.7-2.5% Ti, ?9.0% Mo, ?8.0% W, ?2% Mn, ?1.0% Si, ?2.0% Al, ?0.5% C, ?0.032% O, ?0.032% N,?0.01% S, ?0.02% P, and balance being Fe and unavoidable impurities. The process for manufacturing the base material for high temperature alloy includes following steps: providing raw materials according to the target composition; charging the raw materials in a crucible uniformly layer and layer according to a certain sequence, smelting in vacuum condition; after the materials being melted completely, holding the melt at a temperature; and casting ingot, and cooling to obtain a base material for high temperature alloy.

Abstract: Described is a new stand-alone diguanylate cyclase polypeptide having a GGDEF motif and a mutated I-site that does not bind c-di-GMP. We demonstrate that the production yield of c-di-GMP and analogues was significantly increased by mutation of a conserved residue in the putative regulatory I-site.

Abstract: The present application discloses a method for monitoring abnormal state of Internet information. The method includes obtaining frequency data for current date common words appearing on the current date web pages, combining with a hot words dictionary that Internet users focuses on to determine a list of current date keywords related to the Internet information, determining a weight of each current date keyword, determining an abnormal threshold of the current date keywords, and detecting an abnormal level of the current date keywords to determine current date hot Internet information. The disclose method further calculates an abnormal level of keywords by monitoring the change in the hot words frequency in the Internet information, and generates warning for the abnormal level of hot words frequency change, which allows the Internet users to respond at the first moment.

Abstract: A method for monitoring abnormal state of Internet information by monitoring the change of hot words frequency in the Internet information. The method includes the following steps: 1) obtaining the current date word frequency data of common words appearing in the current date web pages; 2) combining with the hot words dictionary that the user focuses on to determine the current date keywords set of the Internet information; 3) determining the weight of each current date keyword; 4) determining the abnormal threshold of the current date keywords; 5) detecting the abnormal level of the current date keywords to determine the current date hot Internet information. The present invention calculates the abnormal level of keywords by monitoring the change of hot words frequency in the Internet information, predicts and gives alarm for the abnormal level of hot words frequency change, which makes the Internet information user react at the first moment.
