Sentence examples for harvesting terms from inspiring English sources

The main difficulty is that the techniques used in continuous population models with harvesting terms are generally not available to population models with harvesting terms on time scales.

For example, Hou [4] discussed a ratio-dependent predator prey system with multiple harvesting terms.

Wei [5] discussed a three-species periodic predator prey system with Holling III type functional response and harvesting terms.

In this paper, a class of neutral delay Nicholson's blowflies model with leakage delays and linear harvesting terms is considered.

The results of this paper could be generalized to Nicholson's model involving multiple delays and multiple linear harvesting terms.

This paper is concerned with a class of neutral Nicholson blowflies models with leakage delays and linear harvesting terms.

We consider a discrete Nicholson's blowflies model involving a linear harvesting term.

This paper is concerned with a discrete Nicholson's blowflies model, which involves a linear harvesting term.

Following this trend, we study the almost periodic behavior of a discrete analogue of Nicholson's blowflies model involving a linear harvesting term of form (1.3).

We refer the reader to [7, 9 11, 13, 14, 16] and references therein for some of recent works on the Nicholson's blowflies model with harvesting term.

Especially, Berezansky et al. [6] proposed the following Nicholson's blowflies model with linear harvesting term: x'(t)=-delta x t)+px t-tau e^{-gamma x(t-tau)}-H(t-sigma). Since the work of Berezansky et al. [6], it has attracted much attention of many researchers to study the qualitative properties of the Nicholson's blowflies model with harvesting term.
