Mathematical Models of Hysteresis
Physical Review Letters, 1986A new approach to Preisach's hysteresis model, which emphasizes its phenomenological nature and mathematical generality, is briefly described. Then the theorem which gives the necessary and sufficient conditions for the representation of actual hysteresis nonlinearities by Preisach's model is proven.

Mathematical Modelling of Angiogenesis
Journal of Neuro-Oncology, 2000Angiogenesis, the formation of blood vessels from a pre-existing vasculature, is a process whereby capillary sprouts are formed in response to externally supplied chemical stimuli. The sprouts then grow and develop, driven initially by endothelial cell migration, and organize themselves into a branched, connected network.

Mathematical Modeling in Neuroendocrinology [PDF]
Comprehensive Physiology, 2015 ABSTRACTMathematical models are commonly used in neuroscience, both as tools for integrating data and as devices for designing new experiments that test model predictions. The wide range of relevant spatial and temporal scales in the neuroendocrine system makes neuroendocrinology a branch of neuroscience with great potential for modeling.

JAMA, 1965
Scientific investigation is a particular search for a comprehensive view of nature; it is, in effect, a matter of proposing questions concerning phenomena and then searching for the answers in a systematic manner. An important aspect of this investigation, therefore, is the separation of the currently answerable from the unanswerable questions.

Mathematical models for positioning
1992The code pseudorange at an epoch t can be modeled, cf. Eq. (6.2), by $$R_{i}^{j}(t) = \varrho _{i}^{j}(t) + c\Delta \delta _{i}^{j}(t).$$ (8.1) Here, R i j (t) is the measured code pseudorange between the observing site i and the satellite j, ϱ i j is the geometric distance between the satellite and the observing point, and c is the speed of ...

Mathematical modelling of metabolism
Current Opinion in Plant Biology, 2000Modelling of metabolism attempts to improve our understanding of metabolic regulation by quantifying essential parts or aspects of the metabolic system. Three areas in which modelling has recently made considerable contributions toward this aim can be identified.

Mathematical Modeling and Pure Mathematics
Mathematics Teaching in the Middle School, 2015Common situations, like planning air travel, can become grist for mathematical modeling and can promote the mathematical ideas of variables, formulas, algebraic expressions, functions, and statistics.

In this chapter we derive the system characterizing the stationary oscillations of thin elastic plates with transverse shear deformation proposed in [56]. We assume that the body forces have a time-harmonic form, which we substitute into the full classical three-dimensional elasticity model to obtain a time-independent system.

The Arithmetic Teacher, 1972
Although there is reasonable agreement about which mathematical ideas should be taught in the elementary school (Begle 1966) and that these ideas should be taught meaningfully (Dawson and Rud-dell [a] 1955), there is little agreement on how learning environments should be structured to facilitate this learning.
