Branching diffusions in random environment
Branching process random environment diffusion approximation Laplace transform survival probability backbone construction
2011/9/6
Abstract: We consider the diffusion approximation of branching processes in random environment (BPREs). This diffusion approximation is similar to and mathematically more tractable than BPREs. We obta...
The Nature of Star Formation at 24 microns in the Group Environment at 0.3 < z < 0.55
Nature Star Formation Group Environment
2011/10/8
Galaxy star formation rates (SFRs) are sensitive to the local environment; for example, the high-density regions at the cores of dense clusters are known to suppress star formation. It has been sugges...
Preparation of Environment-Friendly Composite from Waste Paper Fiber and Waste Collagen
Composite Waste Collagen Waste Newspaper Fiber
2011/12/15
Waste newspaper fiber was filled in the collagen cross-linked by glutaraldehyde. The effects of deinking fiber, glycerol dosage, glutaraldehyde dosage on the mechanical properties of composite were in...

Cable-Stayed Bridge Field Investigation Numerical Simulation West Midlands Region Wind Environment
2011/12/16
The area of mountain ridge accounts for the most part of our country land. With the development of economic construction, more and more long span bridges have been built in the mountainous region of t...
Characteristics of Atmospheric Elemental Carbon (Char and Soot) in Ultrafine and Fine Particles in a Roadside Environment, Japan
Black carbon (BC) Ultrafine particles Char-EC Soot-EC Diesel exhausts
2016/3/28
Atmospheric carbonaceous components, particularly char and soot in ultrafine particles (UFPs; Dp < 0.1 m) and fine
particles (FPs; Dp < 2.5 m), were measured four times during one...
Changes in Tropical Cyclone Number in the Western North Pacific in a Warming Environment as Implied by Classical Thermodynamics
Second Law of Thermodynamics Global Warming Thermal Wind Relation Sea Surface Temperature
2013/3/6
Observational analyses show that the equatorial trough in the western North Pacific (WNP) is a well-known origin for tropical cyclones (TC) which have tended to weaken in intensity and decrease in num...
HESS Opinions: Hydrologic predictions in a changing environment: behavioral modeling
Hydrologic predictions changing environment behavioral modeling
2011/3/15
Most hydrological models are valid at most only in a few places and cannot be reasonably transferred to other places or to far distant time periods. Transfer in space is difficult because the models a...
