The present invention is natural cell regulating factor P and its preparation process. It is prepared through screening Gram-positive coccus, Gram-negative coccus or bacillus, freezing preservation of strain, conventional culture of the strain at 4-38 deg.c, filtering to filter out harmful thallus while leafing beneficial thallus or extracting natural gene, adding aspartic acid into the natural gene, safety inspection and forming into oral liquid or freeze dried powder. The natural cell regulating factor P product has aspartic acid content the same as that of natural cell regulating factor P. It has the functions of activating and strengthening immune, strengthening TC, repairing and regenerating cell tissue, vessel and epithelium, etc.

The invention discloses a method for denoising a video based on a surfacelet conversion characteristic. The method comprises the following steps of: inputting a video to be denoised; acquiring a high-frequency sub-band coefficient; estimating a noise standard difference; acquiring the energy of a corresponding scale of the surfacelet domain of the video to be denoised; acquiring the regulating factor of the high-frequency sub-band; acquiring a basic threshold value; acquiring the regulating factor of the high-frequency sub-band coefficient; acquiring the threshold value of the high-frequency sub-band coefficient; acquiring a high-frequency sub-band coefficient of the surfacelet domain of the denoised video; and acquiring the denoised video. According to the method, a video and noise are distinguished by using the surfacelet coefficient, so that the relevance existing between the pixel and the frame of the video image is fully utilized, the noise can be effectively removed, and the edge detailed information of the video image can be better kept simultaneously.

The invention relates to the field of molecular microbiology, in particular to an anti-copper binary signal conduction-system regulating factor mutant, as well as a construction and application thereof. The anti-copper binary signal conduction-system regulating factor mutant is a base sequence in a sequence list SEQ ID No.1. The expression method comprises the following steps that pseuclomones fluorescens TSS1 is used as a template, and a product obtained by the PCR amplification of primers CRF19 and CRR9 is used to connect an expression plasmid pLC1 to obtain a plasmid pLC104, the latter undergoes a restriction digestion by SwaI and is then connected with a plasmid pJR20 to obtain a plasmid pJC104 which is transformed into the pseuclomones fluorescens TSS1 to obtain a strain of TSS1 / Pjc104. The regulating protein obtained from the method provided by the invention is a pseuclomones fluorescens anti-copper systemic regulating factor mutant, the expression of which in the pathogenic pseuclomones fluorescens TSS1 can significantly decrease bacterial virulence.

The invention discloses a method for culturing fungi and planting tall gastrodia tuber indoors, which comprises the following steps of: firstly, taking raw materials comprising 90 to 110 parts of saw dust, 50 to 70 parts of wheat bran, 15 to 25 parts of corn flour, 1 to 3 parts of brown sugar and 1 to 3 parts of gypsum powder, and uniformly mixing the raw materials to obtain a mixed filler; and cleaning a fungi culture chamber, and fumigating and sterilizing the fungi culture chamber by using sulfur; partitioning a fungi material into small logs of 15 centimeters, binding the small logs and filling the small logs into a strain bag, tamping gaps in the strain bag by using the prepared mixed filler, then binding the bag mouth, performing sterilization, cooling and inoculation, and finally putting the strain bag into the fungi culture chamber. The growth and development states of hypha can be observed at any time and any place by indoor fungi culture, the growth and the development of the hypha can be affected by regulating factors such as temperature, moisture, illumination and the like for the growth of the hypha in time, the polluted strain bags are cleaned in time, the strain bags which do not produce the hypha can be used for secondary inoculation, and the bag mouths of the strain bags which produce the hypha slowly can be loosened to increase oxygen and promote the growth of the hypha, thus, improving the success rate of the fungi hypha.

The invention discloses a bitter-gourd nutritious food with an auxiliary hypoglycemic effect, which is prepared from the following raw materials in parts by weight: 20-30% of soybean flour, 10-25% of expanded powder, 10-25% of maltodextrin, 5-15% of whole milk powder, 1-15% of ultrafine bitter-gourd powder, 1-10% of activated oat fiber and 1-3% of inulin. The invention further discloses a preparation method of the bitter-gourd nutritious food. The bitter-gourd nutritious food contains a variety of blood sugar regulating factors such as bitter-gourd polysaccharides, saponins and activated oat fiber, has delicate taste, is convenient to eat and easy to accept by the consumers and can be used as the dietary supplement or diet substitute to assist to reducing the blood sugar of the patients with diabetes.

The invention provides a channel estimating method and a system which are based on adjustment factors and used in an orthogonal frequency division multiplexing OFDM system. The method comprises the following steps: when sending the downlink signal, the sending end sends a pilot symbol following one or more OFDM symbols, and the insertion positions of the pilot subcarriers on different pilot symbols in a same sub-frame are different; a receiving end conducts channel estimation after receiving downlink signals, divides the pilot symbols in a same sub-frame into a plurality of groups, for each pilot symbol, the receiving end estimates the channel response of the corresponding sub-carrier on other pilot symbols in the same group according to the channel response on the position of the pilot subcarrier on the pilot symbol, and compares the channel response with the channel response on the position of the pilot subcarrier, calculates the adjustment factors on the position of the corresponding sub-carrier according to the comparison result and the correlativity of the channel time domain, uses the adjustment factors to correct the channel response on the position of the corresponding sub-carrier, and then estimates the channel responses on the positions of all the subcarriers in the sub-frame according to the correction result. The invention further improves performance for estimating channel.
