Diffusion Processes on Manifolds
, 2008 This is an informal introduction to stochastic analysis on both Riemannian and Lorentzian manifolds. We review the basics underlying the construction of diffusions on manifolds, highlighting the important differences between the Riemannian and Lorentzian cases. We also discuss a few recent applications which range from biophysics to cosmology.

On the Transformation of Diffusion Processes into the Wiener Process [PDF]
SIAM Journal on Applied Mathematics, 1980 Necessary and sufficient conditions are given for transforming (constructively) a one-dimensional diffusion process described by a Kolmogorov equation into the Wiener process. These conditions are shown to be equivalent to invariance of a parabolic partial differential equation under a six-parameter Lie group of point transformations.

Diffusion as a Process of Creative Adoption [PDF]
The Journal of Technology Transfer, 2006 This paper elaborates an integrated framework for understanding diffusion as a process of creative adoptions in the business sector. Within the context of the economics of localized technological change, adoption is viewed as a complementary component of a broader process of adjusting the technology when unexpected events in the product and factor ...

FEBS Open Bio, EarlyView.The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.

A spatial model of the diffusion of mobile communications within the European Union [PDF]
Innovation diffusion studies have been popular. However, usually the focus has been on two dimensions: Either the innovation's diffusion is studied on the micro level by examining the individual's adoption of an innovation, or on the macro-level by ...

Possible role of human ribonuclease dicer in the regulation of R loops
FEBS Open Bio, EarlyView.R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible
