Microseismic joint location and anisotropic velocity inversion for hydraulic fracturing in a tight Bakken reservoir
(Society of Exploration Geophysicists, 2014-07)To improve the accuracy of microseismic event locations, we developed a new inversion method with double-difference constraints for determining the hypocenters and the anisotropic velocity model for unconventional reservoirs. ... -
Microseismic mapping and source characterization for hydrofracture monitoring : a full-waveform approach
(Massachusetts Institute of Technology, 2013)The objective of this thesis is to improve the microseismic mapping capability for hydrofracture monitoring by using full-waveform information and understand fracturing mechanisms via microsesimic source mechanism inversion. ... -

Microstimulation Activates a Handful of Muscle Synergies
(Elsevier, 2012-12)Muscle synergies have been proposed as a mechanism to simplify movement control. Whether these coactivation patterns have any physiological reality within the nervous system remains unknown. Here we applied electrical ... -
Microstimulation of primate neocortex targeting striosomes induces negative decision-making
(Wiley, 2019-08)Affective judgment and decision-making are strongly modulated by the pregenual anterior cingulate (pACC) and caudal orbitofrontal (cOFC) cortical regions. By combining MRI-guided electrical microstimulation with viral ... -
Microstress cycle and contact fatigue of spiral bevel gears by rolling-sliding of asperity contact
(Tsinghua University Press, 2020-01-04)Abstract The rolling contact fatigue (RCF) model is commonly used to predict the contact fatigue life when the sliding is insignificant in contact surfaces. However, many studies reveal that the sliding, ... -
Microstrip-antenna-coupled distributed feedback terahertz quantum-cascade lasers
(SPIE, 2013-12-18)By introducing coupled microstrip antennas on THz Distributed Feedback (DFB) Quantum Cascade Lasers (QCLs), the radiation efficiency of each feedback aperture is greatly enhanced. Single mode emission ∼3 THz from a 31-period ... -
