The Efficiency-Incentive Tradeoff in Double Auction Environments
Double Auction Environments Effi ciency-Incentive Tradeoff
2015/7/15
We consider the tradeoff between efficiency and incentives in large double auction
environments with weak budget balance. No mechanism simultaneously gives agents
perfect incentives to be...
Modeling stomatal conductance in the earth system: linking leaf water-use efficiency and water transport along the soil–plant–atmosphere continuum
earth system leaf water-use effi ciency
2014/12/19
The Ball–Berry stomatal conductance model is
commonly used in earth system models to simulate biotic
regulation of evapotranspiration. However, the dependence
of stomatal conductance (gs) on vapor ...
A model using marginal efficiency of investment to analyze carbon and nitrogen interactions in terrestrial ecosystems (ACONITE Version 1)
marginal effi ciency investment to analyze carbon
2014/12/19
Carbon (C) and nitrogen (N) cycles are coupled
in terrestrial ecosystems through multiple processes including photosynthesis, tissue allocation, respiration, N fixation,
N uptake, and decompos...

Eciency Fairness Competitiveness Nash Bargaining Games
2012/11/30
Recently,dened the class of Linear Nash Bargaining Games (LNB) and obtained combinatorial, polynomial time algorithms for several games in this class. also denes two natural subclasses within LNB, UNB...
E±ciency conditions for multiobjective fractional variational problems

Bacterial metabolism and growth efficiency in lakes: The importance of phosphorus availability
Bacterial metabolism growth effi ciency
2014/5/14
We investigated bacterial responses to variations in dissolved organic carbon (DOC) and nutrient availability by
a comparative analysis of bacterial metabolism in lakes ranging from oligotrophic to e...
Predation efficiency in visual and tactile zooplanktivores
tactile zooplanktivores Predation effi ciency
2014/5/14
Gelatinous zooplanktivores (medusae, siphonophores, and ctenophores) and visual zooplanktivores (fish) interact
through competition, predation, and commensalism. In the search for key factors g...
D-H fractionation in Sporomusa ORIGINAL ARTICLE Blackwell Publishing, Ltd. Hydrogen isotope fractionation during H2 /CO2 acetogenesis: hydrogen utilization efficiency and the origin of lipid-bound hydrogen
ORIGINAL ARTICLE D-H fractionation
2014/4/8
Hydrogen metabolism was studied in the anaerobic bacterium, Sporomusa sp. strain DMG 58, by measuring
natural abundance levels of deuterium in H2
, H2O, and individual fatty acids during acetogenic ...
Effects of ultraviolet-B radiation and vertical mixing on nitrogen uptake by a natural planktonic community shifting from nitrate to silicic acid deficiency
ltraviolet-B radiation vertical mixing
2014/5/20
We investigated the combined effects of mixing regimes and ultraviolet-B radiation (UVBR: 280–320 nm) on
the uptake of nitrate, ammonium, and urea by an estuarine phytoplankton community during a 10-...
Effects of dietary phosphorus deficiency on the abundance, phosphorus balance, and growth of Daphnia cucullata in three hypereutrophic Dutch lakes
dietary phosphorus defi ciency abundance phosphorus balance
2014/5/30
We studied population dynamics, phosphorus balance, and individual growth to evaluate limitation of Daphnia
cucullata by dietary phosphorus (P) in three interconnected, hypereutrophic Dutch lakes. Co...
Orientation in complex chemical landscapes: Spatial arrangement of chemical sources influences crayfish food-finding efficiency in artificial streams
complex chemical landscapes chemical sources infl uences
2014/5/30
Fluid dynamics has been shown to alter ecologically important behaviors of aquatic organisms orienting to distant
chemical sources. Because the fluid dynamics and chemical plumes change across ...
