Integrating Density into Dispersal and Establishment Limitation Equations in Tropical Forests
Forests, 2018 Plant recruitment in tropical forests reflects the chance that seeds arrive at a site resulting in seedling establishment. To inform tropical forest restoration, we ask how seed and seedling densities differentially affect dispersal and establishment ...

DISPERSAL LIMITATION AND PATCH OCCUPANCY IN FOREST HERBS
Ecology, 2000 The distribution of species depends on the availability of suitable habitats, the capacity to disperse to these habitats, and the capacity of populations to persist after establishment.

Forests, 2018 Factors that influence tropical-forest regeneration have been of interest across the tropics. We tested the degree of dispersal and establishment limitation of pioneer and non-pioneer tree species with different dispersal modes and seed sizes, using data

Linear Dispersion Codes with Limited Feedback
IEICE Transactions on Communications, 2007LDCs system with finite-rate error-free feedback is proposed in this letter. The optimal transmission codeword is selected at the receiver and the codeword index is sent to the transmitter. A simple random search algorithm is introduced for codebook generation. Moreover, the max-min singular value criterion is adopted for codeword selection. Simulation

Limit Theorems for Dispersing Billiards with Cusps
Communications in Mathematical Physics, 2011This paper investigates certain probability limit theorems for dispersing billiards with cusps. Since these systems enjoy only polynomial decay of correlations of order \(1/n\), they exhibit weak and delicate statistical properties. The authors first prove the central limit theorem (CLT) for dynamical systems under fairly general conditions and then ...

Error Limits in Dispersion Analysis
Optical Interference Coatings, 1997There is a wide variety of methods for determination of the optical functions N(λ)=n(λ)+ik(λ) or ε(w)=ε1(ω)+iε2(ω), often named "constants", from experimental measurements.1 The methods can be split into two main categories a) One measurement over an extended wavelength range and b) two (or more) measurements at a single wavelength.

Theoretical Limits for the Dispersion Limited Optical Channel
2006In this paper, we study the theoretical limits of optical communication channels affected by chromatic dispersion. By using as a metric the energy transfer ratio, we find the optimal transmitted pulse shape that allows minimizing the impact of dispersion, together with an interesting definition of the dispersive channel equivalent bandwidth. This paper,

Limitations to dispersion relations
Annals of Physics, 1960Abstract We attempt to understand the limitations to the validity of dispersion relations by considering fourth-order terms for elastic scattering in perturbation theory. For the exchange scattering of equal mass, scalar, neutral bosons, we obtain Δ max 2 = 2 m 2 for the limit of the validity of the general proof, but closer inspection shows ...

Spatial autocorrelation and dispersal limitation in freshwater organisms
Oecologia, 2008Dispersal can limit the ranges of species and the diversity of communities. Despite its importance, little is known about its role in freshwater habitats and its relation to habitat type (lentic vs. lotic), especially for organisms with cryptic dispersal methods such as plankton.
