Long range dispersal and spatial pattern formation in biological invasions

Mathematical Biosciences, 2006
In this paper we explore the consequences of long distance dispersal in biological invasion processes through simulations using a recently developed cellular automaton model. We show that long distance dispersal generate characteristic spatial patterns with several stationary scale-invariant properties.

Dispersion in the ocean by physical, geochemical and biological processes

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1986
The physical, geochemical and biological processes that lead to the dispersion of radionuclides throughout the marine environment and to interactions with man and his food chain are outlined. Although much remains to be understood about the details of these processes, certain limits may be put on radionuclide transport rates.

Control of the Biological Dispersion of Therapeutic Proteins

1990
Proteins have immense structural variety and variability, ergo their consideration and use of therapeutic agents able to elicit a pharmacological response. As for conventional drugs, much of today’s activity with therapeutic proteins in classical research and development environments ignores the issues of site(s) of action and routes, rates, and ...

Inverse Problems for Dispersive Biological Media

1990
Recently electromagnetic pulses with widths of picoseconds, 10−12 s, and even femtoseconds, 10−15 s, have become available. This opens a new field of inquiry called ultrafast spectroscopy. This new family of tools also provides new ways to look at old problems.

Ultrasonic absorption and dispersion in biological media: A postulated model

The Journal of the Acoustical Society of America, 1982
An integrated approach for the absorption of ultrasound by liquids and tissues is proposed from the solution of a one-dimensional wave equation of propagation. The proposed model explains the square and linear power dependence of absorption on frequency for liquids and tissues, respectively. The study also provides a new index, specific heat ratio (γ),

Theory of broadband dispersion of permittivity of biological cell suspensions

Colloid Journal, 2010
The classical Pauly-Schwan electrical model of the biological cell is generalized by considering the diffusion processes that occur due to the selective (with respect to ions of different signes of charges) conductivity of surface cell structures (cytoplasmic membrane and electrical double layer).

On the FDTD Formulations for Biological Tissues With Cole–Cole Dispersion

IEEE Microwave and Wireless Components Letters, 2010
The rationale behind several previously reported FDTD formulations for directly implementing fractional-ordered Cole-Cole models is investigated from another perspective. The explicit expressions of their numerical permittivities are derived, respectively, which makes a quantitative comparison of their modeling ability on a Cole-Cole medium possible ...
