Data subset selection by Boolean calculation
(Elsevier, 1984-11)
In this journal in 1969 the authors described an unconventional method, based on concepts from systematic biology, for storing and retrieving data, whose salient features are: (1) data are stored in such a manner that the ...
A reaction-diffusion system of a predator-prey-mutualist model
(Elsevier, 1986-04)
Mutualism is part of many significant processes in nature. Mutualistic benefits arising from modification of predator-prey interactions involve interactions of at least three species. In this paper we investigate the ...
Reproduction numbers and thresholds in stochastic epidemic models I. Homogeneous populations
(Elsevier, 1991-12)
We compare threshold results for the deterministic and stochastic versions of the homogeneous SI model with recruitment, death due to the disease, a background death rate, and transmission rate [beta]cXY / N. If an infective ...
An idealized concept of the true cladistic character
(Elsevier, 1975-04)
Estimating evolutionary relationships is basic to the objectives of systematics. Comparative data, structured as taxonomic characters, are usually the essential considerations on which such estimates are founded. Some ...
Physiological changes during the adaptation of hybridoma cells to low serum and serum-free media
(Wiley Subscription Services, Inc., A Wiley Company, 1991-01-05)
Two murine hybridoma cell lines (167.4G5.3 and S3H5/Γ2bA2) were adapted to grow in low-serum and serum-free media by a weaning procedure. The changes in cell growth, metabolic, and antibody production rates with adaptation ...
Effects of dimethyl sulfoxide on the globally ischemic heart: Possible general relevance to hypothermic organ preservation
(Elsevier, 1982-02)
Isolated perfused rabbit hearts were made globally ischemic for 2 hr, then reperfused. For 5 min before and after ischemia hearts were perfused with hypothermic (20 or 27 [deg]C), hypoxic, substrate-free cardioplegic ...
Population balance between producing and nonproducing hybridoma clones is very sensitive to serum level, state of inoculum, and medium composition
(Wiley Subscription Services, Inc., A Wiley Company, 1992-02-05)
Secreting and nonsecreting hybridoma populations derived from the murine hybridoma cell line 167.4G5.3 were each grown in batch culture in low serum and serum-free media. Under serum-free conditions, a secreting population ...
Numerical parameter identifiability and estimability: Integrating identifiability, estimability, and optimal sampling design
(Elsevier, 1985-12)
We define two levels of parameters. The basic parameters are associated with the model and experiment(s). However, the observations define a set of identifiable observational parameters that are functions of the basic ...
