2. Materials and Methods 2.1. Theoretical FormulaAt present, the calculation methods of gas–liquid phase equilibrium usually include the equation of state method, activity coefficient method and so on. The equation of state method is usually suitable for the calculation under medium and high pressure and can obtain the corresponding thermodynamic properties. Therefore, the equation of state method is used to calculate the gas–liquid phase equilibrium of the binary mixed system.

Animals such as raccoon dogs, mink and muskrats are farmed for fur and are sometimes used as food or medicinal products1,2, yet they are also potential reservoirs of emerging pathogens3. Here we performed single-sample metatranscriptomic sequencing of internal tissues from 461 individual fur animals that were found dead due to disease. We characterized 125 virus species, including 36 that were novel and 39 at potentially high risk of cross-species transmission, including zoonotic spillover. Notably, we identified seven species of coronaviruses, expanding their known host range, and documented the cross-species transmission of a novel canine respiratory coronavirus to raccoon dogs and of bat HKU5-like coronaviruses to mink, present at a high abundance in lung tissues. Three subtypes of influenza A virus—H1N2, H5N6 and H6N2—were detected in the lungs of guinea pig, mink and muskrat, respectively. Multiple known zoonotic viruses, such as Japanese encephalitis virus and mammalian orthoreovirus4,5, were detected in guinea pigs. Raccoon dogs and mink carried the highest number of potentially high-risk viruses, while viruses from the Coronaviridae, Paramyxoviridae and Sedoreoviridae families commonly infected multiple hosts. These data also reveal potential virus transmission between farmed animals and wild animals, and from humans to farmed animals, indicating that fur farming represents an important transmission hub for viral zoonoses. Fur farming represents an important hub of cross-species transmission for viral zoonoses.

1. IntroductionThe classification and identification of underwater acoustic targets are important in the fields of marine resource exploitation and national defense [1,2]. Among them, effective ship target recognition technology is pivotal for rights protection cruises and monitoring of infringing vessels in sensitive territories.

4.2. Denoising Experiment of Test Signals 4.2.1. SVMD of Simulation SignalsTo verify the effectiveness and feasibility of the proposed method, the SVMD-FuDE-WPD was applied to four test signals. Taking the Blocks signal as an example, the noisy Blocks (−6 dB) was decomposed using SVMD into eight IMFs. Figure 3 shows the decomposition results of the noisy Blocks. In Figure 3, the frequency increases with the increase in IMF order.
