Sentence examples for evolutionary delay from inspiring English sources

We will restrict our attention to systems modeled by evolutionary delay equations that can be expressed in the form x'(t)=fbigl(x t),x t-tau bigr), quad x t-tau bigrn}, t gequad (1.1) Here the 'state' of the system at time t is (x t)), whose rate of change depends explinitly, via the function f, on the past state (x(t-tau)) wheRe^{n}s a fixed time delay.

This evolutionary delay might have been caused by climate changes in Africa.

Conway Morris (2003) further argues that catastrophic events such as asteroid impacts or other major extinction events can delay evolutionary events but ultimately affect only the timing, not the eventual, inexorable result.

The oscillation of solutions for delayed evolutionary equations has received widespread attention; see, for example, [8 14] and the references therein.

Hence, the effects of the periodic environment on evolutionary equations with delays have been the object of intensive analysis by numerous authors, some of the results can be found in [13 18] and the references therein.

Based on individual-based simulations, Claessen et al. (2007) reported delayed evolutionary branching and proposed two reasons: random genetic drift and extinction of incipient branches.

In order to obtain the oscillation of solutions, we first consider the existence and uniqueness conditions of the positive equilibrium of equation (1.1) and give conditions for nonexistence of ultimately positive solution or negative solution of the evolutionary p-Laplacian with delay.

The architecture, called Time-delay Added Evolutionary Forecasting (TAEF), consists of two steps: parameters optimization and phase adjustment.

Furthermore, an experimental analysis is conducted with the proposed method through four Brazilian stock market time series, and the achieved results are discussed and compared to results found with random walk models and the previously introduced Time-delay Added Evolutionary Forecasting (TAEF) and Morphological-Rank-Linear Time-lag Added Evolutionary Forecasting (MRLTAEF) methods.

Sozou's evolutionary theory proposed that hyperbolic delay discounting may be totally attributable to aversion to a decrease in subjective probability of obtaining delayed rewards (SP) which follows a hyperbolic decay function.

In order to explain hyperbolic discounting for delayed rewards, an evolutionary theorist Sozou proposed the following two assumptions [ 13]: (A) subjective probability of obtaining delayed rewards decays hyperbolically, (B) the subjective value of a delayed reward equals a statistical expected value in terms of subjective probability.
