Dynamic Size Counting in Population Protocols [PDF]

open access: yes, 2022
The population protocol model describes a network of anonymous agents that interact asynchronously in pairs chosen at random. Each agent starts in the same initial state s. We introduce the dynamic size counting problem: approximately counting the number

Ecological importance of lepidopteran defoliators on eucalyptus plantations based in faunistic and natural enemy analyses [PDF]

open access: yesBrazilian Journal of Biology, 2023
Areas planted with Eucalyptus urophylla S.T. Blake variety platyphylla F. Muell. (Myrtaceae) expand annually in most regions of Brazil. Many lepidopteran species defoliate this plant, but with damage varying per species.

Resource allocation with population dynamics [PDF]

open access: yes2017 55th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2017
Many analyses of resource-allocation problems employ simplistic models of the population. Using the example of a resource-allocation problem of Marecek et al. [arXiv:1406.7639], we introduce rather a general behavioural model, where the evolution of a heterogeneous population of agents is governed by a Markov chain.

The Cotton Mealybug, Phenacoccus Solenopsis Tinsley (Homoptera : Pseudococcidae) as a New Insect on Soybean Plants in Egypt and its Population Dynamic [PDF]

open access: yesJournal of Plant Protection and Pathology, 2017
The cotton mealybug, Phenacoccus  solenopsis Tinsley (Homoptera :Pseudococcidae) is an important insect pest worldwide causing economic damage to several crops. The insect was noticed for the first time on soybean, Glycine max L. plants (var.

Population Dynamics in River Networks [PDF]

open access: yesJournal of Nonlinear Science, 2019
Natural rivers connect to each other to form networks. The geometric structure of a river network can significantly influence spatial dynamics of populations in the system. We consider a process-oriented model to describe population dynamics in river networks of trees, establish the fundamental theories of the corresponding parabolic problems and ...

A Dynamical Model for Human Population [PDF]

open access: yesProceedings of the National Academy of Sciences, 1974
We analyze a simple, deterministic model of the dynamics of population changes in a bisexual, reproductive system based on marriage. Our model is one of a general class, special cases of which have been previously discussed within the framework of population biology by D. G. Kendall, L. A. Goodman, J. H. Pollard, and others.

POPULATION DYNAMICS [PDF]

open access: yesJournal of the American Mosquito Control Association, 2007
This chapter reviews aspects of population dynamics that may be conceptually important for biological control of mosquitoes. Density dependent population regulation among immature stages has important implications for biological control of mosquito populations, primarily because it can lead to compensatory or overcompensatory mortality due to additions
