Acoustic Visualization of Patch Dynamics in Oceanic Ecosystems
Land ecosystem dynamics plankton
2015/8/17
Over the past 25 years, investigations of patch dynamics in terrestrial and intertidal ecosystems have thoroughly revised our concepts of the processes structuring many natural communities (Levin et a...
Ecology of a Chaetoceros socialis Lauder Patch on Georges Bank: Distribution, Microbial Associations, and Grazing Losses
Georges Bank: Distribution Microbial Associations
2015/8/6
The presence of patches and layers in marine pelagic ecosystems may play an important role in providing food for higher trophic levels at concentrations high enough to support the metabolism, growth, ...
Low friction along the high slip patch of the 2011 Mw 9.0 Tohoku-Oki earthquake required from the wedge structure and extensional splay faults
Low friction along the high slip patch 2011 Mw 9.0 Tohoku-Oki earthquake required the wedge structure extensional splay faults
2014/4/15
We analyze the mechanical properties needed to account for the large shallow slip during the 2011 Tohoku-Oki earthquake and the activation of landward normal faulting within the forearc. We show that ...
Patch exploitation by planktivorous fish and the concept of aggregation as an antipredation defense in zooplankton
zooplankton antipredation defense
2014/4/2
Contrary to the suggestion that swarming can be used as an antipredation defense in zooplankton, the
individual risk of a planktonic prey (Daphnia) increased rather than decreased with prey density u...
Geometric continuity and compatibility conditions for 4-patch surfaces
4-patch surface tangent plane continuity curvature continuity compatibility conditions
2010/11/29
When considering regularity of surfaces, it is its geometry that is of interest. Thus, the concept of geometric regularity or geometric continuity of a specific order is a relevant concept. In this pa...
Patch behaviour and predictability properties of modelled finite-amplitude sand ridges on the inner shelf
Patch behaviour predictability properties modelled finite-amplitude sand ridges inner shelf
2009/11/2
The long-term evolution of shoreface-connected sand ridges is investigated with a nonlinear spectral model which governs the dynamics of waves, currents, sediment transport and the bed level on the in...
Using a spatio-temporal dynamic state-space model with the EM algorithm to patch gaps in daily riverflow series
patch gaps daily riverflow series
2009/5/18
A spatio-temporal linear dynamic model has been developed for patching short gaps in daily river runoff series. The model was cast in a state-space form in which the state variable was estimated using...
Partial rupture of a locked patch ofthe Sumatra megathrust during the 2007 earthquake sequence
Partial rupture a locked patch Sumatra megathrustearthquake sequence
2014/4/15
The great Sumatra-Andaman earthquake and tsunami of 2004 was a dramatic reminder of the importance of understanding the seismic and tsunami hazards of subduction zones1-4. In March 2005, the Sunda meg...
Full-spectrum study of small patch of sky yields portrait of maturing universe（图）

2007/3/12
6 March 2007，BERKELEY – A massive project to generate an all-color map of the galaxies in a small area of sky, utilizing four satellite telescopes and four ground-based telescopes, is yielding new inf...
