A Potential Earthquake with Magnitude Mw 7.2 on the Northern Xiaojiang Fault Revealed by GNSS Measurement

open access: yesRemote Sensing, 2023
We used near-field and regional GNSS (Global Navigation Satellite System) data to quantify the deformation and locking ratio of the Xiaojiang fault (XJF) in southeastern Tibet.

Laser photothermoacoustic heterodyned lock-in depth profilometry in turbid tissue phantoms [PDF]

open access: yesPhysical Review E, 2005
Frequency-domain correlation and spectral analysis photothermoacoustic FD-PTA imaging is a promisingnew technique, which is being developed to detect tumor masses in turbid biological tissue. Unlike conventional biomedical photoacoustics which uses time-of-flight acoustic information induced by a pulsed laser to indicate the tumor size and location, in

Design and Simulation Analysis of Docking Interface of Linked In-Orbit Replacement Module

open access: yesMachines, 2023
On-orbit service for spacecraft relies heavily on on-orbit docking with the orbital replacement unit docking interface. Foreign research on the docking interface of the orbit replaceable unit has been in-depth, while the domestic work is still limited ...

Locking Status and Earthquake Potential Hazard along the Middle-South Xianshuihe Fault

open access: yesRemote Sensing, 2018
By combining the seismogenic environment, seismic recurrence periods of strong historical earthquakes, precise locations of small⁻moderate earthquakes, and Coulomb stress changes of moderate⁻strong earthquakes, we analyze the potential ...

Passive Mode-Locking of Monolithic InGaAs/AlGaAs Double Quantum Well Lasers at 42GHz Repetition Rate [PDF]

open access: yes, 1990
Pulse trains with a 42GHz repetition rate were generated by monolithic InGaAs/AlGaAs double quantum well lasers at a wavelength of 985 [angstroms]. The cavity was electrically divided into three regions, one providing gain and the other two providing ...

Present‐Day Activity of the Anninghe Fault and Zemuhe Fault, Southeastern Tibetan Plateau, Derived From Soil Gas CO2 Emissions and Locking Degree

open access: yesEarth and Space Science, 2021
The Anninghe fault (ANHF) and the Zemuhe fault (ZMHF), located in the southeast of the Tibetan Plateau, have a high level of seismic hazard and are among the most active faults in China.

Effect of surface waves on full depth lock exchange gravity currents hydrodynamics [PDF]

open access: yesRiver Flow 2016, 2016
Hydrodynamics of full depth lock exchange gravity currents is investigated by means of a numerical model which takes into account both surface wave propagation and gravity currents. The adopted modeling approach couples a Boussinesq-type of model for surface waves and a gravity current model for stratified flows.

Estimates of Seismic Potential in the Marmara Sea Region from Block Models of Secular Deformation Constrained by Global Positioning System Measurements [PDF]

open access: yes, 2014
We model the geodetically observed secular velocity field in northwestern Turkey with a block model that accounts for recoverable elastic-strain accumulation. The block model allows us to estimate internally consistent fault slip rates and locking depths.

Slip rates and spatially variable creep on faults of the northern San Andreas system inferred through Bayesian inversion of Global Positioning System data [PDF]

open access: yes, 2014
Fault creep, depending on its rate and spatial extent, is thought to reduce earthquake hazard by releasing tectonic strain aseismically. We use Bayesian inversion and a newly expanded GPS data set to infer the deep slip rates below assigned locking ...
