Mathematical methods and models for radiation carcinogenesis studies

Mathematical methods and models for radiation carcinogenesis studies.

Research on radiation carcinogenesis requires a twofold approach. Studies of primary molecular lesions and subsequent cytogenetic changes are essential, but they cannot at present provide numerical estimates of the risk of small doses of ionizing radiations. Such estimates require extrapolations from dose, time, and age dependences of tumor rates observed in animal studies and epidemiological i...

Symplectic and symmetric methods for the numerical solution of some mathematical models of celestial objects

In the last years, the theory of numerical methods for system of non-stiff and stiff ordinary differential equations has reached a certain maturity. So, there are many excellent codes which are based on Runge–Kutta methods, linear multistep methods, Obreshkov methods, hybrid methods or general linear methods. Although these methods have good accuracy and desirable stability properties such as A...

Epidemiologic Studies of Carcinogenesis by Ionizing Radiation

In general, we should like to express our lack of sympathy for the expressed purpose of this Symposium, which is the planning of epidemiological studies for the evaluation of effects of major pollutants on humans. Carcinogenesis and leukemogenesis are two particularly worrisome long term effects which deserve consideration with respect to any pollutant. From our experience with ionizing radiati...
