here, a predator-prey model with hassell-varley type functional responses is studied. some sufficient conditions are obtained for the permanence and global asymptotic stability of the system by using comparison theorem and constructing a suitable lyapunov functional. moreover, an example is illustrated to verify the results by simulation.

This work was designed to investigate individual differences in hands-and-knees crawling and frontal brain electrical activity with respect to object permanence performance in 76 eight-month-old infants. Four groups of infants (one prelocomotor and 3 with varying lengths of hands-and-knees crawling experience) were tested on an object permanence scale in a research design similar to that used b...

Children who have been removed from their parents need stability and permanence; this is as true for disabled children as it is for others. Yet many children are subject to extended periods of uncertainty and instability.

The primary goals of reserve selection are to represent all chosen units of biodiversity and to ensure their long-term persistence while minimizing costs. We considered two simple proxies of species persistence: a time series of point-count data to calculate abundance and a time series of presence-absence data to calculate permanence (a measure of consistent occupancy over time). Using two 10-y...

Recognizing people based on their biological or behavioral characteristics, called biometric authentication, has been applied over hundred years. Two important issues, 1) distinctiveness and 2) permanence should be considered for biometric authentication. Distinctiveness of a biometric refers to that any two persons should be sufficiently different in terms of the features in the biometrics. Pe...
