An efficient method for large-scale slack allocation
timing graph slack allocation delay budgeting convex optimization truncated Newton method
2015/8/7
We consider a timing or project graph, with given delays on the edges and given arrival times at the source and sink nodes. We are to find the arrival times at the other nodes; these determine the tim...
Micro- to Fine-Scale Chemical Gradients and Layers in Stratified Coastal Waters
Stratified Coastal Waters Chemical Gradients and Layers
2015/8/6
Models of biogeochemical dynamics and chemical variability in coastal waters have traditionally relied on the assumption that small-scale mixing processes are sufficiently strong and isotropic to rapi...
Thin Layers: Observations of Small-Scale Patterns and Processes in the Upper Ocean
Small-Scale Patterns Processes
2015/8/6
Fore decades, marine scientists have been asking questions about the response of planktonic distributions and processes to physical forcing across a range of temporal and spatial scales. The mismatch ...
Acoustical Sensing of Small-Scale Vertical Structures in Zooplankton Assemblages
Small-Scale Vertical Structures Zooplankton Assemblages
2015/8/6
Observation of aquatic animals in their natural environments remains a major challenge in both biological oceanography and limnology. Critical processes in feeding, reproduction, growth, and predation...
Small-Scale Planktonic Structure: Persistence and Trophic Consequences
Persistence Trophic Consequences
2015/8/6
Most conventional sampling methods limit our ability to resolve planktonic distributions over vertical scales less than a few meters. Estimates of in situ biological rates also are limited by equipmen...
ICON–ART 1.0 – a new online-coupled model system from the global to regional scale
online-coupled model system regional scale
2015/8/6
We present the first stage of a new online-coupled
global to regional-scale modeling framework for the simulation of the spatiotemporal evolution of aerosols and trace
gases. The underlying me...
A large-scale simulation model to assess karstic groundwater recharge over Europe and the Mediterranean
Europe and the Mediterranean large-scale simulation
2015/8/6
Karst develops through the dissolution of carbonate rock and is a major source of groundwater contributing up
to half of the total drinking water supply in some European
countries.ate rock and is a ...
Comparisons of local infiltration-excess, overland flow and associated erosion behaviour with river behaviour at the catchment scale
Hydrologic modeling overland flow erosion catchment scale
2015/8/6
Modeling overland flow and erosional behaviour is a very important scientific task today to prevent environmental impacts from human activities as well as physical disasters such as floods and deserti...
Toward a Global Scale Coastal Ocean Observing System
Global Scale Coastal Ocean Observing System Ocean Observing System
2015/8/5
The concept of the Global Ocean Observing System (GOOS) is that of an integrated global network that systematically acquires and disseminates data and data products in response to the information need...
NEPTUNE: Real-Time Ocean and Earth Sciences at the Scale of a Tectonic Plate
Real-Time Ocean Earth Sciences
2015/8/5
Since the Challenger Expedition in the 1870s, oceanographers have explored and sampled across two-thirds of our planet using ships as primary observational platforms. In the past several decades, sate...
A Simple Model of Unbounded Evolutionary Versatility as a Largest-Scale Trend in Organismal Evolution
Largest-Scale Trend Organismal Evolution
2015/7/31
The idea that there are any large-scale trends in the evolution of biological organisms is
highly controversial. It is commonly believed, for example, that there is a large-scale trend in
evolution ...

2015/7/30
Many researchers agree on the basic architecture of the "world model" where knowledge about the
world required for organization of agent's intelligent behavior is represented. However, most proposals...
Varied observations over Oregon's continental shelf illustrate the beauty and complexity of geophysical flows in coastal waters. Rapid, creative, and sometimes fortuitous sampling from ships and moori...
Climate-Associated Regime Shifts Drive Decadal-Scale Variability in Recovery of North Atlantic Right Whale Population
Climate-Associated Decadal-Scale Variability North Atlantic Right Whale Population
2015/7/20
Despite an elevated mortality rate from lethal interactions with humans, the North Atlantic right whale population has continued to grow during the first decade of the new millennium. This unexpected ...
A New Database to Explore the Findings from Large-Scale Ocean Iron Enrichment Experiments
New Database Large-Scale Ocean Iron Enrichment Experiments
2015/7/15
Some of the largest scientific manipulation experiments conducted on our planet have enriched broad swaths of the surface ocean with iron. Surface ocean signatures of these iron enrichment experiments...
