A one-dimensional mass and energy balance model was developed to simulate rainfall interception in Sacramento County, California. The model describes tree interception processes: gross precipitation, leaf drip, stem flow, and evaporation. Kriging was used to extend existing meteorological point data over the region. Regional land use/ land cover and tree canopy cover were parameterized with dat...

Trees play a crucial role in the water, carbon and nitrogen cycle on local, regional and global scales. Understanding the exchange of momentum, heat, water, and CO 2 between trees and the atmosphere is important to assess the impact of drought, deforestation and climate change. Unfortunately, ground measurements of tree properties such as mass and canopy interception of precipitation are often ...

In cycler and semi-cycler Mars mission architectures a crew “taxi” docks with the interplanetary transfer vehicle on a hyperbolic flyby trajectory, hence the term “hyperbolic rendezvous.” An algorithm that guides the taxi to intercept the transfer vehicle is presented with a control law for final approach. When navigation and thrust uncertainties are included, the vehicles dock at a closing rat...

This paper presents a new framework for modeling light interception by isolated trees which makes it possible to analyze the in uence of structural tree organization on light capture. The framework is based on a multiscale representation of the plant organization. Tree architecture is decomposed into a collection of components representing clusters of leaves at di erent scales in the tree crown...

Artificial night light has the potential to significantly alter visually-dependent species interactions. However, examples of disruptions of species interactions through changes in light remain rare and how artificial night light may alter predator-prey relationships are particularly understudied. In this study, we examined whether artificial night light could impact prey attraction and interce...

When faced with a fly ball approaching along the sagittal plane, fielders need information for the control of their running to the interception location. This information could be available in the initial part of the ball trajectory, such that the interception location can be predicted from its initial conditions. Alternatively, such predictive information is not available, and running to the i...

Determination of the intercept of the BFKL pomeron is one of the pressing issues in the high energy physics. Earlier we have shown that, at the dipole size r = r∆ = (0.1− 0.2)f, the dipole cross section σ(x, r) which is a solution of the generalized BFKL equation, exhibits a precocious asymptotic behavior σ(x, r) ∝ ( 1 x )∆IP . In this paper we discuss how measuring FL(x,Q ) and ∂FT (x,Q )/∂ lo...

A small proportion of children exhibit extreme and persistent conduct problems through childhood. The present study employed the multiple-domain model of Greenberg and colleagues as the framework for person-oriented analyses examining whether parent-child attachment combines with parenting, family ecology, and child characteristics in particular configurations of risk that are linked to this pr...
