Abstract: A write request directed to the non-volatile memory device is received. A stripe associated with an address specified by the write request is present in the volatile memory device is determined. The volatile memory device includes a plurality of stripes, each stripe of the plurality of stripes having a plurality of managed units. The write request on a managed unit of the stripe in the volatile memory device is performed. The stripe in the volatile memory device is evicted to a stripe in the non-volatile memory device.

Abstract: The present invention pertains to the field of nutrition and medicine, and relates to a drug combination for anti-aging and its use.

Abstract: The invention relates to a method for fermentation production of DHA, in particular a method for producing DHA through solid culture and liquid fermentation of Schizochytrium. The method comprises steps of activation of a strain, preparation of a suspension of the strain, preparation of a primary seed, preparation of a secondary solid seed, enlarging cultivation of the secondary solid seed in a fermentor, collection of cells after fermentation, and extraction of DHA oil. With the fermentation method, the seed preparation method is improved, the seed enlarging technology is simplified, the period of seed culture and fermentation is shortened, and therefore the investment is reduced and the cost is saved; in addition, the solid culture medium is of eutrophy and rich in a plurality of growth factors, and is more beneficial to the growth of the seed; cells are strong in viability and good in synchronism in solid culture medium.

Abstract: The present invention discloses a multi-rotor structure applied to an unmanned aerial vehicle, and belongs to the technical field of unmanned aerial vehicles. The unmanned aerial vehicle includes a fuselage, first rotors, second rotors and rotor shafts; and the multi-rotor structure includes first rotary connecting pieces and second rotary connecting pieces.
