Predators often consume multiple prey and by mutually subsidizing a shared predator, the prey may reciprocally harm each other. When predation levels are high, this apparent competition can culminate in a prey species being displaced. Coupling quantitative genetics and Lotka-Volterra models, we study how predator evolution alters this and other ecological outcomes. These models account for a tr...

We take it for granted that objects continue to exist after being occluded. This knowledge - known as object permanence - is present even in childhood, but its neural basis is not fully understood. Here, we show that monkey inferior temporal (IT) neurons carry potential signals of object permanence even in animals that received no explicit behavioral training. We compared two conditions with id...

Concept drift means that the concept about which data is obtained may shift from time to time, each time after some minimum permanence. Except for this minimum permanence, the concept shifts may not have to satisfy any further requirements and may occur infinitely often. Within this work is studied to what extent it is still possible to predict or learn values for a data sequence produced by dr...

This study was an investigation of the effects of a motor handicap on the development of object permanence in the young child. Motor abilities were evaluated for 12 infants aged 13 to 29 months. Based on this evaluation, the children were described as manipulators or nonmanipulators in reference to their upper extremity skills. Their stage of object permanence was assessed using traditional and...

General dynamic models of systems with two prey and one or two predators are considered. After rescaling the equations so that both prey have the same intrinsic rate of growth, it is shown that there exists a generalist predator that can mediate permanence if and only if there is a population density of a prey at which its per-capita growth rate is positive yet less than its competitor’s invasi...

We study a stochastic SIS (susceptible-infected-susceptible) epidemic dynamics on network, under the effect of Markovian regime-switching. first prove existence unique global positive solution, and find invariant set for system. Then, we sufficient conditions a.s. extinction permanence, showing also their relation with stationary probability distribution Markov chain that governs switching netw...

ABSTRACT Purpose to verify the efficacy of speech therapy in early return oral intake patients with post-orotracheal intubation dysphagia. Methods It was a double-blinded randomized controlled trial for two years intensive care units hospital. Study inclusion criteria were orotracheal intubation>48hours, age≥18 old, clinical stability, and Exclusion tracheotomy, score 4 7 Functional Oral Int...
