Stabilized two-phase material point method for hydromechanical coupling problems in solid–fluid porous media
Pubblicazione 2025-08-01Testo<p>For the hydromechanical coupling of solid–fluid porous media, this study presents an explicit stabilized two-phase material point method (MPM) formulation based on the one-point two-phase MPM scheme. To mitigate the spurious pore pressure and maintain the numerical stability, stabilized tec...

Large Gradient Subsidence Monitoring in Mining Area Based on LuTan-1 SAR Images
Pubblicazione 2025-08-01TestoLarge gradient subsidence induced by coal mining generally results in limited applicability of interferometric synthetic aperture radar technique, and even fails to obtain complete and reliable deformation details for mining area. To solve this problem, the LuTan-1 SAR data with L-band and high spat...

Threshold studies of coherent synchrotron radiation induced microwave instability beyond adiabatic approximation
Pubblicazione 2025-07-01TestoIn typical studies of collective effects in a storage ring, an important assumption is that the longitudinal bunch length remains constant over one turn, which is referred to as the adiabatic approximation. This approximation is reasonable for conventional storage rings. However, for extremely short...

Superfluid-Cooled Transmon Qubits under Optical Excitation
Pubblicazione 2025-07-01TestoMicrowave-to-optical quantum state transfer enables the interconnection of remote superconducting quantum processors via optical-fiber links. Achieving high conversion efficiency necessitates an intense optical pump, yet direct optical exposure of superconducting circuits often degrades their perfor...

Rethinking Habitability Using Biogenic Precursors: Formaldehyde in Millimeter Molecular Clouds of the Inner Galaxy
Pubblicazione 2025-01-01TestoWe present a comprehensive study of formaldehyde (H _2 CO) absorption and radio recombination line (H _110 _α ) emission in 215 molecular clouds from the Bolocam Galactic Plane Survey, observed using the Nanshan 25 m radio telescope. H _2 CO was detected in 88 sources (40.93%) with 59 being new dete...
