Numerous mammalian taxa exhibit reproductive delays, pauses in reproduction that occur between mating and fertilization, between fertilization and implantation of the embryo, or after an embryo has implanted. Of the 27 mammalian orders, 9 are known to exhibit reproductive delays, including Diptrotodontia, Dasyuromorphia, Eulipotyphyta, Cingulata, Carnivora, Rodentia, Chiroptera, Lagomorpha and ...

This paper deals with fuzzy cellular neural networks (FCNNs) with leakage delays and proportional delays. Applying the differential inequality strategy, fixed point theorem and almost periodic function principle, some sufficient criteria which ensure the existence and global attractivity of a unique almost periodic solution for fuzzy cellular neuralnetworks with leakage delays and p...

This letter studies the consensus tracking control for multi-agent systems (MASs) of general linear dynamics considering heterogeneous constant known input and communication delays under a directed graph containing spanning tree. First, open-loop stable MASs, distributed predictive observer is proposed to estimate error construct that does not involve any integral term (which time-efficient in ...

Abstract This paper studies the general decay synchronization (GDS) of a class nonautonomous bidirectional associative memory recurrent neural networks (BAMRNNs) with mixed time delays. By employing Lyapunov method and useful inequality techniques, some sufficient conditions on for BAMRNNs are derived. In addition, an example numerical simulations is presented to illustrate obtained theoretical...

Abstract. New necessary and sufficient conditions for the asymptotic stability of positive 2D linear systems with delays described by the general model, Fornasini-Marchesini models and Roesser model are established. It is shown that checking of the asymptotic stability of positive 2D linear systems with delays can be reduced to the checking of the asymptotic stability of corresponding positive ...

This work investigates the representational and inductive capabilities of time-delay neural networks (TDNNs) in general, and of two subclasses of TDNN, those with delays only on the inputs (IDNN), and those which include delays on hidden units (HDNN) . Both architectures are capable of representing the same class of languages, the definite memory machine (DMM) languages, but the delays on the h...

ABSTRACT. We study impulsive Cohen-Grossberg neural networks with S-type distributed delays. This type of delays in the presence of impulses is more general than the usual types of delays studied in the literature. Using analysis techniques we prove the existence of a unique equilibrium point. By means of simple and efficient Lyapunov functions we present some sufficient conditions for the expo...

It is known that task scheduling problem of a complete kary intree with unit time tasks and general communication delays onto an unlimited number of processors is NP-complete. In this paper, we show that such a problem can be solved in linear time if we restrict communication delays within the range from (k− 1) to k unit times. We also show that naive scheduling is optimal if communication dela...
