The objectives of this study are to better understand controls on bed erodibility in muddy estuaries, including the roles both sediment properties and recent hydrodynamic history. An extensive data set measurements, properties, information was utilized create statistical models predict bed. This includes >160 eroded mass versus applied stress profiles collected over 15 years along York R...

Background: Negative regulatory mechanisms of ROCK signaling are poorly understood. We have discovered a novel mechanism to attenuate ROCK signaling. Results: Coronin1B is a novel binding partner of ROCK2 that inhibits ROCK signaling to myosin. Conclusion: Coronin1B regulates ROCK by a novel signal attenuation mechanism. Significance: Coronin1B attenuation of ROCK signaling is associated with N...

Rock bolts have been widely used as rock reinforcing members in underground coal mine roadways and tunnels. Failures of rock bolts occur as a result of overloading, corrosion, seismic burst and bad grouting, leading to catastrophic economic and personnel losses. Monitoring the health condition of the rock bolts plays an important role in ensuring the safe operation of underground mines. This wo...

[1] Experimental data for alteration of synthetic Martian basalts at pH = 0–1 indicate that chemical fractionations at low pH are vastly different from those observed during terrestrial weathering. Rock surface analyses from Gusev crater are well described by the relationships apparent from low-pH experimental alteration data. A model for rock surface alteration is developed, which indicates th...

In terms of target detection and classification, scattering from exposed rock on the seafloor, (i.e., individual rocks and rock outcrops) presents some of the most difficult challenges for modern MCM and ASW sonar systems in shallow water. Work on characterizing, modeling and simulating mean levels and other statistical measures of acoustic scattering from rocks and rock outcrops is therefore c...
