A Prediction Model Based on the Long Electrode Source for Fault Anomaly in Tunnel
Geofluids, 2023 The resistivity method has been widely used to predict the water-bearing structure of tunnels. The traditional resistivity uses the point electrode (PE) source in the tunnel to excite the electric field.

Signal from noise retrieval from one and two-point Green's function - comparison
, 2015 We compare two methods of eigen-inference from large sets of data, based on the analysis of one-point and two-point Green's functions, respectively. Our analysis points at the superiority of eigen-inference based on one-point Green's function. First, the

New point-like sources and a conducting surface in Maxwell–Chern–Simons electrodynamics
European Physical Journal C: Particles and Fields, 2020 We investigate some aspects of the Maxwell–Chern–Simons electrodynamics focusing on physical effects produced by the presence of stationary sources and a perfectly conducting plate (mirror).

2SXPS: An Improved and Expanded Swift X-Ray Telescope Point-source Catalog [PDF]
Astrophysical Journal Supplement Series, 2019 We present the 2SXPS (Swift-XRT Point Source) catalog, containing 206,335 point sources detected by the Swift X-ray Telescope (XRT) in the 0.3–10 keV energy range. This catalog represents a significant improvement over 1SXPS, with double the sky coverage
