OESbathy version 1.0:a method for reconstructing ocean bathymetry with generalized continental shelf-slope-rise structures
OESbathy version 1.0 ocean bathymetry continental shelf-slope-rise structures
2015/9/10
We present a method for reconstructing global ocean bathymetry that combines a standard plate cooling model for the oceanic lithosphere based on the age of the oceanic crust, global oceanic sediment t...
Breccia of Frog Lakes:reconstructing Triassic volcanism and subduction initiation in the east-central Sierra Nevada, California

2015/1/16
The Antler and Sonoma orogenies occurred along the southwest-trending passive Pacific margin of North America during the Paleozoic concluding with the accretion of the McCloud Arc. A southeast-trendin...
RECONSTRUCTING PAST ANTARCTIC ICE FLOW PATHS IN THE ROSS EMBAYMENT, ANTARCTICA USING SAND PETROGRAPHY, PARTICLE SIZE AND DETRITAL ZIRCON PROVENANCE
Provenance Antarctica zircons Till
2015/1/16
Tills for this study were analyzed from sites in East Antarctica (EA), West Antarctica (WA) and along a transect in the Ross Sea. Particle size, sand petrography, and detrital zircons were used to pro...
Reconstructing the East Asian monsoon response to major volcanic eruptions: A test of model skill with instrumental and paleoclimate data
Volcanic eruption climate change ancient climate records volcanoes the tropics precipitation
2014/10/22
Global and regional-scale climatic changes caused by volcanic eruptions are difficult to discern conclusively based on limited 20th century climate records. Analyses of paleoclimate records and global...
Reconstructing Structured Sparse Signals from Compressive Samples via a Max-Product EM Algorithm
Belief propagation expectation maximization (EM) algorithm hidden Markovtree(HMT) max-productalgo-rithm,structured sparsity,sparse signal reconstruction.
2012/11/22
We propose a Bayesian expectation-maximization (EM) algorithm for reconstructing structured approximately sparse signals via belief propagation. The measurements follow an underdetermined linear model...
Hypersaline waters pose new challenges for reconstructing environmental histories of fish based on otolith chemistry
Hypersaline waters pose new challenges reconstructing environmental histories fish based otolith chemistry
2014/4/4
We investigated the effect of hypersaline conditions on the water chemistry of the Coorong Lagoon, the terminal estuary of Australia's largest river, and the otolith chemistry of a common fish within ...

Wind and Water: the two competing but major formative processes in sculpturing Murray Basin landscapes. How do we uncouple those processes in environmental analysis?Evidence of progressive reduction i...
Avoiding bias in reconstructing the largest observable scales from partial-sky data
Avoiding bias reconstructing largest observable partial-sky data
2011/10/18
Obscuration due to Galactic emission complicates the extraction of information from cosmological surveys, and requires some combination of the (typically imperfect) modeling and subtraction of foregro...

We derive a method to reconstruct Gaussian signals from linear measurements with Gaussian noise. This new algorithm is intended for applications in astrophysics and other sciences. The starting point ...
A Two-Tiered Correlation of Dark Matter with Missing Transverse Energy: Reconstructing the Lightest Supersymmetric Particle Mass at the LHC
Correlation Dark Matter Missing Transverse Energy Reconstructing Lightest Supersymmetric
2011/10/18
We suggest that non-trivial correlations between the dark matter particle mass and collider based probes of missing transverse energy H_T^miss may facilitate a two tiered approach to the initial disco...
