In order to improve the reaction efficiency and rate of Al powder with seawater, highly active Al base powder (Al-Mg-Sn-Bi alloy powder, AMSB) was prepared by adding low melting metal (Sn and Bi) by atomizing. The hydrogen generation rate and open ci

Investigating line-locked phenomena within quasars is crucial for understanding the dynamics of quasar outflows, the role of radiation pressure in astrophysical flows, and the star formation history and metallicity of the early universe. We have init

The inter-band lags among the optical broad-band continua of active galactic nuclei (AGNs) have been intensively explored over the past decade. However, the nature of the lags remains under debate. Here utilizing two distinct scenarios for AGN variab

We report the evidence of a hidden black hole (BH) in a low-mass galaxy, MaNGA 9885-9102, and provide a new method to identify active BH in low mass galaxies. This galaxy is originally selected from the MaNGA survey with distinctive bipolar H$\alpha$

Galactic-wide outflows driven by active galactic nuclei (AGNs) is a routinely invoked feedback mechanism in galaxy evolution models. Hitherto, the interplay among the interstellar gas on galactic scales, the propagation of AGN outflows and the fundam

Wireless Capsule Endoscopy (WCE) is highly valued for its non-invasive and painless approach, though its effectiveness is compromised by uneven illumination from hardware constraints and complex internal dynamics, leading to overexposed or underexpos

The FEM has been widely adopted to solve electromagnetic field problems. The accuracy of FEM is highly effected by the number of system units and the complexity of computational order,leading to low computational efficiency. In order to improve the c
