Parasite transmission in size-structured populations
Ecology, 2022Abstract Host heterogeneity can impact parasite transmission, but determining underlying traits and incorporating them into transmission models remains challenging. Body size is easily measured and influences numerous ecological interactions, including transmission.

The effect of sample particle size on the determination of pore structure parameters in shales
International Journal of Coal Geology, 2016 The combination of low-pressure N-2 and CO2 adsorption could provide an effective approach for characterizing the pore structure of shales. Although gas adsorption methods generally do not destroy the pore structure during experimental process, sample ...

Bounds on the Size of Ultrametric Structures
Physical Review Letters, 1986We present theorems on the possible sizes of ultrametric and almost-ultrametric structures and discuss implications for the entropy of spin-glasses, the traveling salesman problem, and neural network memories.

Capacitive nature of atomic-sized structures
Physical Review B, 1995The capacitance of an N-electron system is established by deriving the atomistic connection between the capacitive energy, the ionization potential, and the electron affinity of the charged system; it is shown further that this connection leads to the linkage of the capacitive energy to the difference between the lowest unoccupied and the highest ...

Size, Structure and Devaluation
SSRN Electronic Journal, 2015Exchange rate devaluations have been used by economies around the world in an attempt to enhance their external price competitiveness. This paper evaluates the efficacy of this strategy in small-island developing states. We classify countries around the world into two broad categories, large or small according to population, land area and economic size,

On the Structure of Semiovals of Small Size
Journal of Combinatorial Designs, 2013AbstractThe classification of all semiovals and blocking semiovals in PG(2, 8) is determined. Also, new theoretical results on the structure of semiovals containing a‐secant and some nonexistence results are presented.

Structure Size Enhanced Histogram
2009Direct volume visualization requires the definition of transfer functions (TFs) for the assignment of opacity and color. Multi-dimensional TFs are based on at least two image properties, and are specified by means of 2D histograms. In this work we propose a new type of a 2D histogram which combines gray value with information about the size of the ...

The Evolution of Size in Size-Structured Populations
1988In many populations of animals and plants, particularly those with indeterminate growth, size is the dominant ecological attribute of individuals (see Caswell 1982 and this Vol.; Peters 1983; Werner and Gilliam 1984; Sauer and Slade 1987; Sebens 1987). Understanding the evolution of size is therefore critical to understanding the population biology of ...

Optimal Size at Maturity in Size-Structured Populations
Journal of Theoretical Biology, 1997Abstract Maturity is a critical point in the life cycle, and determining the optimal age or size at maturity is a classical problem in life history theory. Most organisms spend some time in non-reproductive immature stage. To explain the widespread occurrence of delayed maturity, a number of authors made mathematical models with the age-specific ...
