Competitively Coupled Maps and Spatial Pattern Formation
Competitively Coupled Maps Spatial Pattern Formation
2012/4/26
Spatial pattern formation is a key feature of many natural systems in physics, chemistry and biology. The essential theoretical issue in understanding pattern formation is to explain how a spatially h...
Spatial and temporal trends for water-fl ow velocity and bed-material sediment transport in the lower Mississippi River
Spatial and temporal trends water-fl ow velocity bed-material sediment transport the lower Mississippi River
2014/4/8
Where rivers near the coastline, the receiving basin begins to infl uence fl ow, and gradually varied, nonuniform fl ow conditions arise. The section of the river affected by nonuniform fl ow is typic...
Dynamics of optomechanical spatial solitons in dual-nanoweb structures
Dynamics of optomechanical spatial solitons dual-nanoweb structures Optics
2012/4/20
We theoretically investigate the stability and dynamics of self-channelled beams that form via nonlocal optomechanical interactions in dual-nanoweb microstructured fibers. These "optomechanicons" repr...
Spatial distribution of intact polar lipids in North Sea surface waters: Relationship with environmental conditions and microbial community composition
Spatial distribution intact polar lipids North Sea surface waters Relationship with environmental conditions microbial community composition
2014/4/4
We characterized and quantified the intact polar lipid (IPL) composition of the surface waters of the North Sea and investigated its relationships with environmental conditions, microbial abundances, ...
Real-world road networks have an approximate scale-invariance property; can one devise mathematical models of random networks whose distributions are {\em exactly} invariant under Euclidean scaling? T...

We characterized and quantified the intact polar lipid (IPL) composition of the surface waters of the North Sea and investigated its relationships with environmental conditions, microbial abundances, ...
Internalwavesandmixingin theepilimnionof a lake affects spatial patterns of zooplankton in a body-size dependent manner
stratifi cation, wind, plankton distribution
2014/4/1
Zooplankton are not uniformly distributed in space but are patchy at multiple scales as a result of
interactions between their directed motion and both large- and small-scale water currents. Using &#...
Interplay between mutational pathway and spatial drug distribution controls time to evolution of drug resistance
Interplay mutational pathway spatial drug distribution controls time evolution of drug resistance
2012/2/28
Spatial gradients of drug concentration are believed to play an important role in the evolution of drug resistance. We use a stochastic model to show that in a growing population of malignant cells th...
Constraining dynamical dark energy with a divergence-free parametrization in the presence of spatial curvature and massive neutrinos
Constraining dynamical dark energy divergence-free parametrization presence spatial curvature massive neutrinos
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...
The role of mineral surfaces in the preservation and transformation of organic carbon: meso- to nano– scale spatial complexity of organic matter forms in organic-rich shales
mineral surfaces preservation transformation organic carbon meso- to nano– scale spatial complexity organic matter forms organic-rich shales
2012/3/30
Sequestration of organic matter (OM) in sediments is a fundamental biogeochemical process that regulates planetary temperature, the flux of free oxygen to the atmosphere and oceans, and the distributi...
4Pi focusing of spatial ly modula ted radially polarized vorte x beams
4 Pifocusing spatially modulated radially polarized vortex beams
2013/7/3
We propose a method for generating focal beams with special intensity distributions using radially polarized vortex beams in a 4Pi configuration. A spherical dark-hollow beam and hollow beam array can...
The spatial variation of coercivity on patterned magneto-optical ~MO! materials has been studied with a Kerr microscope. Our results show that the coercivity values on arrays made by holes are larger ...
