Finite linnaean structures
Springer Science and Business Media LLC - Tập 29 - Trang 191-206 - 1967
This paper considers a class of set-theoretical entities, calledn-rank Linnaean structures, which are intended as abstract models of the taxonomic classificatory systems of biology. In the first part, devoted to formalism, finite Linnaean structures are discussed in complete generality; but, in addition, eight distinct subclasses are noted and some of the properties of their elements are explored....... hiện toàn bộ
A note on the interpretation of perseveration in discrimination
Springer Science and Business Media LLC - Tập 20 - Trang 261-265 - 1958
The effect of one judgment upon the next judgment in a discrimination situation is considered to be the result of two types of perseveration. One arises from the judgment itself. The other results from a persistence, from one trial to the next, of a transient bias. It is shown that the resulting perseveration can then be a function of the difficulty of the first of the pair of choices. Expressions...... hiện toàn bộ
Stochastic kinetic models for small irreversible systems
Springer Science and Business Media LLC - Tập 36 - Trang 219-227 - 1974
The probability distribution of the process level is derived for a general class of irreversible reaction systems. A method of approximating the mean and variance of the process level is developed and shown to be more accurate for small irreversible systems than other approximations used in the stochastic approach to kinetics.

Evolution of Defence Portfolios in Exploiter–Victim Systems
Springer Science and Business Media LLC - Tập 69 - Trang 957-988 - 2007
Some organisms maintain a battery of defensive strategies against their exploiters (predators, parasites or parasitoids), while others fail to employ a defence that seems obvious. In this paper, we shall investigate the circumstances under which defence strategies might be expected to evolve. Brood parasites and their hosts provide our main motivation, and we shall discuss why the reed warbler Acr...... hiện toàn bộ
Spatial Model for Oncolytic Virotherapy with Lytic Cycle Delay
Springer Science and Business Media LLC - Tập 81 - Trang 2396-2427 - 2019
We formulate a mathematical model of functional partial differential equations for oncolytic virotherapy which incorporates virus diffusivity, tumor cell diffusion, and the viral lytic cycle based on a basic oncolytic virus dynamics model. We conduct a detailed analysis for the dynamics of the model and carry out numerical simulations to demonstrate our analytic results. Particularly, we establish...... hiện toàn bộ
A new model for laser-induced thermal damage in the retina
Springer Science and Business Media LLC - Tập 65 - Trang 731-746 - 2003
We describe a new model for laser-induced retinal damage. Our treatment is prompted by the failure of the traditional approach to accurately describe the image size dependence of laser-induced retinal injuries and by a recently reported study which demonstrated that laser injuries to the retina might not appear for up to 48 h post exposure. We propose that at threshold a short-duration, laser-indu...... hiện toàn bộ
Pattern regulation in reaction-diffusion systems-the problem of size invariance
Springer Science and Business Media LLC - Tập 47 Số 4 - Trang 475-487 - 1985
A Lie group topology for normal and abnormal human behavior
Springer Science and Business Media LLC - Tập 31 - Trang 275-293 - 1969
A Lie-topology of human behavior has been generated in terms of a group of continuous transformations in multidimensional reactivity-adaptability coordinates, connections between the conscious and unconscious surfaces being made through a finite number of interpretive parameters. Neuroses and personality disorders are mathematically classified in terms of pure rotation groups, while reactive depre...... hiện toàn bộ
The left ventricle as confocal prolate spheroids
Springer Science and Business Media LLC - Tập 31 - Trang 433-439 - 1969
A model of left ventricle is described which takes into account the physiologic variations of thickness, a function of time and distance prior to and during ejection, by assuming that the prolate spheroids are confocal at a given instant. The hyperbolic segment of arc between innermost and outermost spheroids, confocal with the latter, defines a so-called functional thickness, for which a derivati...... hiện toàn bộ
