Abstract: This invention relates to the field of biomedicine and specifically to a porcine interferon-like recombinant protein and its applications. By constructing and screening a PoIFN-? DNA shuffling bacterial library, a highly active recombinant protein Porferon was obtained. Porferon exhibits potent anti-infective activity against a broad range of porcine pathogens, including viruses, bacteria, and parasites. Its biological activity is significantly superior to that of natural porcine interferon. As such, Porferon can be used in the development of therapeutics for the prevention or treatment of infectious diseases in pigs, offering a novel and effective solution for clinical applications in veterinary medicine.

Abstract: Embodiments of this application disclose a random access method and apparatus.

Abstract: The present invention discloses a low signal-to-noise ratio (SNR) seismic event detection model based on a deep residual shrinkage network (DRSN). Considering the different noises contained in seismic records acquired by different seismic sensors, a DRSN based on a residual network was constructed to detect seismic events from low SNR seismic records. In the constructed network, a soft thresholding function (a shrinkage function) was inserted into the deep network structure as a nonlinear transform layer to effectively filter the impact of noise-related features, and an attention mechanism, together with an adaptive soft thresholding block, was also incorporated to automatically obtain the optimal denoising threshold for seismic signals, which ensures different signals are processed to the best effect. After training, the DRSN adaptively determines the denoising threshold so that each seismic signal has its own threshold set and seismic events can be accurately detected under strong background noise.
