Abstract: Provided is a backflow cascade novel process for producing a lithium-7 isotope. The process comprises an upper backflow section, an extraction section, an enrichment section, a lower backflow section, and a product acquiring section. Upper backflow phase-conversion liquid and lower backflow phase-conversion liquid are respectively added to the upper backflow section and the lower backflow section, and upper backflow phase-conversion liquid and lower backflow phase-conversion liquid of the lithium material are controlled; the product is precisely acquired in the product acquiring section; an organic phase is added to the upper backflow section, and is recycled in the lower backflow section. By means of cascade connection with a high-performance liquid separator, environmental protection, high efficiency, and multi-level enrichment of the lithium-7 isotope are achieved, and a high-abundance lithium-7 isotope product is obtained.

Abstract: A transconductance-enhancing passive frequency mixer comprises a transconductance amplification stage, a frequency mixing stage, and an output transresistance amplifier. The transconductance amplification stage has a pre-amplification transconductance-enhancing structure, so that the transconductance is greatly enhanced, thereby obtaining the same transconductance value at a lower bias current. A radio-frequency current is modulated by the frequency mixing stage to generate an output mid-frequency current signal. The mid-frequency current signal passes through the transresistance amplifier, to form voltage output, and finally obtain a mid-frequency voltage signal. The transresistance amplifier has a transconductance-enhancing structure, thereby further reducing input impedance, and improving current utilization efficiency and port isolation. The frequency mixer has the characteristics of low power consumption, high conversion gain, good port isolation, and the like.

Abstract: A stochastic time-digital converter (STDC) including an input switching circuit, an STDC array, and an encoder. A clock circuit inputs two clock signals into two input terminals of the input switching circuit; the input switching circuit transmits the two clock signals in a cyclic cross-transposition form to two input terminals of the STDC array, and simultaneously outputs a trigger control signal to the encoder; each comparator in the STDC array independently judges the speeds of the two clock signals and sends the judgement results to the encoder for collection and processing; and the encoder outputs the size and positivity or negativity of the phase difference of the two clock signals. The technical solution utilizes the stochastic characteristic of the STDC to double the number of the equivalent comparators in the STDC array, eliminating the effects on the circuitry of device mismatching and processes, power supply voltage, and temperature.

Abstract: The present invention provides novel MDCK-derived adherent non-tumorigenic cell lines that can be grown in the presence or absence of serum. The cell lines of the present invention are useful for the production of vaccine material (e.g., viruses). More specifically, the cell lines of the present invention are useful for the production of influenza viruses in general and ca/ts influenza viruses in particular. The invention further provides methods and media formulations for the adaptation and cultivation of MDCK cells such that they remain non-tumorigenic. Additionally, the present invention provides methods for the production of vaccine material (e.g., influenza virus) in the novel cell lines of the invention.
