Modeling and analyzing HIV transmission: the effect of contact patterns
(Elsevier, 1988-12)
A compartmental model is presented for the spread of HIV in a homosexual population divided into subgroups by degree of sexual activity. The model includes constant recruitment rates for the susceptibles in the subgroups. ...
A covalently linked DNA-RNA molecule from human leukemia cells
(Elsevier, 1973-02-20)
An enzyme complex was prepared from the cytoplasm of a continuous line of monocytic human leukemia cells isotopically labeled in culture. Such preparations carry out RNA dependent DNA synthesis using endogenous primers and ...
Vascular tumor growth and treatment: Consequences of polyclonality, competition and dynamic vascular support
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2002-03)
A mathematical model is presented to describe the evolution of a vascular tumor in response to traditional chemotherapeutic treatment. Particular attention is paid to the effects of a dynamic vascular support system in a ...
The spread and persistence of infectious diseases in structured populations
(Elsevier, 1988)
A basic assumption of many epidemic models is that populations are composed of a homogeneous group of randomly mixing individuals. This is not a realistic assumption. Most actual populations are divided into a number of ...
The stochastic SI model with recruitment and deaths I. comparison with the closed SIS model
(Elsevier, 1993)
We compare the stochastic and deterministic version of an SI model with recuitment, background deaths, and deaths due to the disease. For the stochastic version, analysis of the mean number of susceptibles, m, and infecteds, ...
Macrophage response to Mycobacteriumtuberculosis infection
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2004-02)
The immune response to Mycobacteriumtuberculosis (Mtb) infection is the formation of multicellular lesions, or granolomas, in the lung of the individual. However, the structure of the granulomas and the spatial distribution ...
