Transpirational water use and its regulation in the mountainous terrain of S. Korea
(American Geophysical Union, 2009)
Quantifying water use by forests growing on complex mountainous terrain is difficult and understanding of controls on water use by these forests a challenge. Yet mountains are crucial as water towers and better understanding ...
A comparison of CO2 fluxes via eddy covariance measurements with model predictions in a dominant subtropical forest ecosystem
(Copernicus Publications, 2009)
CO2 fluxes were measured continuously for twelve months (2003) using eddy covariance technique at canopy layer in a dominant subtropical forest in South China. Our results showed that daytime maximum CO2 fluxes of the whole ...
Responses of CO2 exchange and primary production of the ecosystem components to environmental changes in a mountain peatland
(Springer Science+Business Media, 2009)
The complexity of natural ecological systems presents challenges for predicting the impact of global environmental changes on ecosystem structure and function. Grouping of plants into functional types, that is, groups of ...
Overcoming the Challenges of Estimating Water Use in Temperate, Mixed Deciduous Forest of S. Korea
(American Geophysical Union, 2009)
About 80% of forests in Korea occur in mountainous regions and are composed of a rich diversity of mixed deciduous tree species. Mountains in this region receive more rainfall and act as fountains that supply fresh water ...
The algebra of smooth functions of rapid descent
(2009)
A bounded operator with the spectrum lying in a compact set V ⊂ R, has C∞ (V) functional calculus. On the other hand, an operator H acting on a Hilbert space H, admits a C(R) functional calculus if H is self-adjoint. So ...
Operators with slowly growing resolvents towards the spectrum
(Academic Publications, 1/13/2009)
A closed densely defined operator H, on a Banach space X, whose spectrum is contained in R and satisfies
(z −H)−1
≤ c hziα |=z|β ∀ z 6∈ R (0.1) for some α , β ≥ 0; c > 0, is said to be of (α, β)−type R . If instead of (0.1) ...
On the structures of quotient groups
(Academic Publications, 5/22/2009)
Let J be the Jacobson radical of a commutative completely primary
finite ring R such that J
k 6= (0) and J
k+1 = (0). Then R/J ∼= GF(p

The algebra of smooth functions of rapid descent
(2009)
A bounded operator with the spectrum lying in a compact set V ⊂
R, has C∞(V ) functional calculus. On the other hand, an operator H acting on
a Hilbert space H, admits a C(R) functional calculus if H is self-adjoint. So ...
