Constraining the dynamics of volcanic eruptions by characterization of pumice textures
Phlegraean Fields Plinian eruptions vesicle textures magma ascent dynamics
font style='font-size:12px;'>
2015/9/10
We have characterized the textures of pumice clasts from Phlegraean Fields to gain insights into the conduit
flow-dynamics of alkaline explosive eruptions. Vesicularities, vesicle number densities, a...
Constraining fault interpretation through tomographic velocity gradients: application to northern Cascadia
Constraining fault interpretation velocity gradients
font style='font-size:12px;'>
2015/1/4
Spatial gradients of tomographic velocities are
seldom used in interpretation of subsurface fault structures.
This study shows that spatial velocity gradients can be used
effectively in identifying...

2012/2/21
In this paper, we report the results of constraining the dynamical dark energy with a divergence-free parameterization, $w(z) = w_{0} + w_{a}(\frac{\ln(2+z)}{1+z}-\ln2)$, in the presence of spatial cu...
Constraining density functional approximations to yield self-interaction free potentials
Constraining density functional approximations self-interaction free potentials

2011/8/18
Abstract: Self-interactions (SIs) are a major problem in density functional approximations and the source of serious divergence from experimental results. Here, we propose to constrain the effective l...
The WiggleZ Dark Energy Survey: constraining the evolution of Newton's constant using the growth rate of structure
constraining evolution constant using growth rate structure
font style='font-size:12px;'>
2011/10/11
We constrain the evolution of Newton's constant using the growth rate of large-scale structure measured by the WiggleZ Dark Energy Survey in the redshift range $0.1 < z < 0.9$. We use this data in two...
