Designing for Nature and Sustainability
(International Journal of Sustainable Development and World Ecology, 2006)
Humankind is now using natural resources more rapidly than natural systems can replace them and has been doing so for approximately two and one half decades. Moreover, both natural capital and the ecosystem services it ...
Consumerism and the 21st Century
(Science and Society, 2006)
Although people, even nations, worldwide in the 21st century want more material possessions, the United States is pivotal because (1) although it has only 4% of the world s population, it consumes approximately 25% of the ...
The S-wave from the decay
chaotic advection, diffusion, and reactions in open flows
(AIP Publishing, 2000-03)
We review and generalize recent results on advection of particles in open time-periodic hydrodynamical flows. First, the problem of passive advection is considered, and its fractal and chaotic nature is pointed out. Next, ...
Complexity, fractals, disease time, and cancer
(American Physical Society, 2004-12)
Despite many years of research, a method to precisely and quantitatively determine cancer disease state remains elusive. Current practice for characterizing solid tumors involves the use of varying systems of tumor grading ...
Breathing dynamics in heteropolymer DNA
(CELL PRESS, 2007-04)
While the statistical mechanical description of DNA has a long tradition, renewed interest in DNA melting from a physics perspective is nourished by measurements of the fluctuation dynamics of local denaturation bubbles ...
Convergence theorems for intermediate problems. II
(Cambridge University Press, 2002)
Convergence theorems for the practical eigenvector free methods of Gay and Goerisch are obtained under a variety of hypotheses, so that our theorems apply to both traditional boundary-value problems and atomic problems. ...
Texture and structural refinement using neutron diffraction data from molybdite (MoO3) and calcite (CaCO3) powders and a Ni-rich Ni50.7Ti49.30 alloy
(Cambridge University Press, 2009-12)
Preferred orientation or texture is a common feature of experimental powder patterns. The mathematics of two commonly used models for preferred orientation-the March-Dollase and the generalized spherical-harmonic models-is ...
In situ structural and texture analyses of monoclinic phase for polycrystalline Ni-rich T49.86Ni50.14 alloy from neutron diffraction data
(Cambridge University Press, 2008-03)
Phase transformation temperatures of a polycrystalline Ni-rich Ti49.86Ni50.14 shape memory alloy were investigated using a differential scanning calorimeter. In situ structural and texture analyses of the monoclinic ...
Growth of functions in cercles de remplissage
(Cambridge University Press, 2002-02)
Suppose that f is meromorphic in the plane, and that there is a sequence z(n) --> infinity and a sequence of positive numbers epsilon(n) --> 0, such that epsilon(n)\z(n)f(#)(z(n))/log\z(n)\ --> infinity. It is shown that ...
