Abstract: Embodiments of the present disclosure propose an Erasing-based Lossless Floating-point compression method, i.e., Elf. The main idea of Elf is to erase the last few bits (i.e., set them to zero) of floating-point values, so the XORed values are supposed to contain many trailing zeros, where the erased bits are determined based on the decimal place count and the digits on the exponent bits.

Abstract: A traffic distribution method and apparatus in a hybrid access network, where the method includes transmitting, by a hybrid access aggregation point (HAAP), probe traffic using a second tunnel after determining that a first tunnel is congested when user traffic is transmitted over the first tunnel, obtaining, by the HAAP, a status of the first tunnel and a status of the second tunnel, determining, by the HAAP according to the status of the first tunnel and the status of the second tunnel, whether the status of the first tunnel and the status of the second tunnel meet an offloading condition, and transmitting, by the HAAP, the user traffic using the first tunnel and the second tunnel after determining that the status of the first tunnel and the status of the second tunnel meet the offloading condition.

Abstract: The invention discloses an avian infectious bronchitis virus purification method. The method uses ordinary avian embryo which was affected by avian bronchitis virus. Using the combination of centrifugation, ultrafiltration, concentration, molecular sieve chromatography and ultrafiltration method can effectively remove miscellaneous protein in embryo-derived infectious bronchitis virus antigen, high virus recovery, and have no effect on the activity of avian infectious bronchitis virus. The avian infectious bronchitis virus purified by this method can be directly used in the preparation of avian infectious bronchitis virus vaccine.

Abstract: The present invention relates to a medium for culturing the M-arc-145 cell, which consists of the following components: the Dulbecco Modified Eagle Medium (DMEM), the solution of gelatin digested by the enzyme and the fetal calf serum; wherein the volume ratio of said DEME, said solution of hydrolytic gelatin by the enzyme and said fetal calf serum is 1 to 2:1 to 5:2 to 5:100. The present invention furthermore provides a preparation method thereof, that is: obtaining the medium by means of taking the solution of gelatin digested by the enzyme, the DEME solution containing the amino acid and the fetal calf serum with the measuring cylinder according to the quantities in the formula, and mixing these components. The medium for culturing the M-arc-145 cell of the present invention may reduce the usage amount of the fetal calf serum during the preparation, hence decreasing the production cost, and of which the preparation method is rather simple and easy to operation.
