Abstract: The present disclosure provides a method for an accurate well-seismic tie based on stepwise matching and optimization, including: determining target seismic data as a seismic trace near well and performing first data processing on the target seismic data; performing second data processing on the logging information to determine a reflection coefficient sequence; extracting seismic wavelets, convoluting the seismic wavelets with the reflection coefficient sequence, determining a synthetic seismic record of the target calibration object in a time domain, performing third data processing on the synthetic seismic record; determining a correlation between the seismic trace near well and the synthetic seismic record, determining a global time shift between the synthetic seismic record and the seismic trace near well, performing a preliminary alignment on the synthetic seismic record; and calculating a local time shift between the seismic trace near well and the synthetic seismic record and accurately calibrating th

Abstract: The embodiment of the present disclosure provides an imaging method for a dispersion energy spectrum of surface waves, an electronic device, and a storage medium. The imaging method includes: obtaining first surface wave data, and the first surface wave data corresponding to a space-time domain representation; processing the first surface wave data to obtain the second surface wave data, and the second surface wave data corresponding to a space-frequency domain representation; and processing the second surface wave data based on a preset algorithm to obtain a first imaging result, the first imaging result corresponding to a slowness-frequency domain representation.

Abstract: The present disclosure discloses a denoising method and a system for preserving amplitude variation with offset (AVO) features of pre-stack seismic data. The method includes: acquiring seismic wave data at at least one receiving point through a seismic signal acquisition device, and storing the seismic wave data in a memory; in response to ending of an acquisition operation of the seismic signal with the seismic signal acquisition device, determining, based on the seismic wave data in the memory, pre-denoising angle gather data through a processing device; and obtaining and outputting a denoised angle gather signal through inputting the pre-denoising angle gather data to a denoising device and performing denoising processing on the pre-denoising angle gather data based on the denoising device.

Abstract: The present disclosure provides method and composition for protection, prevention, and/or treatment against viral infections via activation of ILCs induced by certain virus, including but not limited to, influenza and/or non-replicating adenoviruses. The present disclosure further provides that activation of ILCs is an intervention strategy against not only influenza viral infectious epidemic and/or pandemic before a strain-matched vaccine is available but also against other viruses for which prophylactic vaccines may not be available.

Abstract: An animal memory training system with a closed rotary maze comprises a maze device and a stimulating device. A rotary wheel (6) driven by a motor (4) is provided on the bottom of the case (1) of the maze device. The motor (4) is set in a central column, and its output shaft is tightly connected with the rotary wheel (6) along the central column shaft direction, thus the rotary wheel (6) is driven by the motor (4) to rotate around said central column. A number of pulleys (12) are set on the lower periphery of the frame of the case (1) to support said rotary wheel (6), and a sieve-like supporting net (5) is arranged above the rotary wheel (6). The stimulating device includes an automatic manipulator stimulating device and a remote control stimulating device. Compared with the existing maze model, the rotary drive action of the training system's rotary wheel is moderate, and is more coincident with the movement actual of animals' normal physiological behavior.
