Abstract: A background offset drift calibration circuit and method for comparator are proposed. The background calibration circuit and method are designed based on the approximate linear characteristic of the offset drift of a comparator caused by the variation of temperature and power supply. The calibration circuit for the comparators obtains the offset drift characteristic of each comparator by performing twice foreground calibration and selects the comparator with the largest drift as the reference comparator and other comparators as working comparators. The reference comparator is configured to track the offset drift and trigger the background calibration circuit of other working comparators. The working comparators compensate for the offset drift caused by the temperature or the power supply in the background by linear interpolation based on the offset drift characteristic of each comparator.

Abstract: A protocol to determine chemical shift-specific T1 constants in inhomogeneous fields. Based on intermolecular double-quantum coherences and spatial encoding techniques, the method can resolve overlapped peaks in inhomogeneous fields using the conventional method. With inversion recovery involved, the amplitude of peaks will be modulated by the time of inversion recovery. After fitting the amplitude curves, the corresponding longitudinal relaxation time can be achieved. With the measured T1 values in inhomogeneous fields, we can have insights into the chemical exchange rates, signal optimization and data quantitation.
Abstract: This invention provides a NMR multi-dimensional method for measuring coupling constants within several coupling networks. At first, a 90° hard pulse was performed to flip the magnetization from the Z axis to the XY plane. After t1/2, a selective 180° pulse is implemented with a simultaneous Z-direction gradient, thus reversing different protons at different slices. Then the PSYCHE element is implemented. After another t1/2, the gradient G1 and Gp are implemented. At last, the EPSI readout is used to simultaneously record both the chemical-shift and the spatial information. As a result, from different specific slices, we can extract the scalar couplings between the proton reversed at this slice and other protons. These couplings lead to splittings in the indirect dimension, from which relevant coupling constants can be measured.

Abstract: The invention relates to a method for embedding a load based on gel high hydrostatic pressure liquefaction. Using the phenomenon that the physical gel is liquefied under high pressure, the vacuum-packaged high-methoxyl pectin gel is treated under a pressure of 400-600 MPa for 5-30 min, mixed with the load, and then subjected to a pressure of 400-600 MPa for homogenization treatment for 5 to 30 min After pressure relief, the liquefied gel is poured into a mold for reshaping, followed by removal of free water and coating treatment. This method combines the advantages of high hydrostatic pressure technology in modification and sterilization. It has mild embedding conditions and wide sources of raw materials to prepare the carrier, which has excellent biocompatibility and biodegradability. It can be widely used for embedding microorganisms, enzymes, proteins and small molecular substances. The loaded gel prepared by the method has high microbial safety, can effectively maintain the activity of the load.

Abstract: A combined cycle propulsion system (CCPS) module combines a low-speed propulsion system (LSPS) such as a turbojet and a high-speed propulsion system (HSPS) such as dual mode ramjet engines with a mid-speed propulsion system (MSPS) such as a ejector ramjet engine to close a thrust gap between the upper operation limit of the LSPS and the lower operation limit of the HSPS in a flight vehicle. A cooling system ensures thermal protection of the non-operating LSPS during MSPS or HSPS operation by cooling tapped air from the MSPS or HSPS using a heat exchanger and expansion in a turbine/generator and directing cooled tapped air into the LSPS.
