Abstract: A rapid detection method for ricin toxin is provided. The rapid detection method for ricin toxin comprises reacting an adenine-containing oligonucleotide chain substrate labeled with a fluorescent group and a quenching group, a buffer solution, a BSA solution, a to-be-detected sample and sterile water, incubating at a constant temperature, detecting a fluorescence signal value, and determining whether the ricin toxin exists based on a difference between an average value of final fluorescence signal values and an average value of final fluorescence signal values of a negative control; wherein the sample is judged as a positive sample when the average value of the detected final fluorescence signal values is greater than the average value of the final fluorescence signal values of the negative control by +3 times standard deviation.

Abstract: A method for configuring and updating random access resources in a multi-antenna multiple-input multiple-output (MIMO) environment is provided, including: initializing a base station; broadcasting, by the base station, the available RACH resources using an SIB2; initiating, by users who have data to be sent in an uplink, random access processes on the RACH resources configured by the base station; and redefining an S state, an I state, and a C state. Configuration of the RACH resources may be gradually and dynamically optimized according to the quantity of antennas of the base station and a utilization rate threshold of the RACH resources, so that waste of random access RACH resources is reduced provided that an MIMO system meets a required user/service access success probability; a utilization of the resources is improved by fully utilizing spatial diversity characteristics of the MIMO system.

Abstract: An aero-engine bearing fault diagnosis method based on variational mode decomposition and residual network includes the following steps: collect signals in different positions and directions with vibration acceleration sensors, which will be used as sample data; convert the said sample data into the target data type through normalization, slicing, variational mode decomposition and labeling, to get a training sample set; build a 1D-Resnet model, input the training sample set into the said 1D-Resnet model for training and save the model parameters when the model converges; diagnose the aero-engine bearing fault with the trained 1D-Resnet model, to get the diagnostic results. The method diagnoses and analyzes faults of the bearings of the rotating mechanical parts in aero-engines based on variational mode decomposition and residual network, which improves the diagnostic accuracy, and can provide an accurate and reliable basis for maintenance workers.

Abstract: A 4,5-disubstituted-1H-pyrrolo(2,3-f)quinolin-2,7,9-tricarboxylate compound, or an analog, or derivative thereof, having a structure of Formula I: R1 and R4 are each independently an atom or group selected from hydrogen, a linear or branched C1-8 alkyl group, a deuterated linear or branched C1-8 alkyl group, an aralkyl group, or a substituted aryl group; R2 is independently an atom or group selected from halogens, a linear or branched C1-8 alkoxy group, or a deuterated linear or branched C1-8 alkoxy group; and R3 is independently an atom or group selected from a linear or branched C1-8 alkoxy group, or a deuterated linear or branched C1-8 alkoxy group. The compound is useful as a reaction intermediate for the synthesis of PQQ. A process in which CAN is used as an oxidant in the synthesis of PQQ in existing patents and literatures is replaced. This makes the process cheaper and more efficient.
