Observable Signature of Merging Stellar-mass Black Holes in Active Galactic Nuclei

open access: yesThe Astrophysical Journal, 2023
The origin of stellar-mass black hole mergers discovered through gravitational waves is being widely debated. Mergers in the disks of active galactic nuclei (AGNs) represent a promising source of origin, with possible observational clues in the ...

Optimization and Transient Analysis of Distributed Asynchronous Condenser

open access: yesIEEE Access, 2022
After the high proportion of new energy is connected, the decrease of the proportion of synchronous machine in power system will cause a series of stability hazards, such as the lack of inertia.

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology

open access: yesAdvanced Engineering Materials, EarlyView.
We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Transient electromagnetic sounding for groundwater

open access: yesGeophysics, 1986
Abstract The feasibility of using the transient electromagnetic sounding (TS or TDEM) method for groundwater exploration can be studied by means of numerical models. As examples of its applicability to groundwater exploration, we study four groundwater exploration problems: (1) mapping of alluvial fill and gravel zones over bedrock ...
