The three dimensional structure of the different types of cytoskeletal filaments (CSK) consti¬ tutes the cell's shape as well as die interior organization of cell organelles. Since changes in the state of cells towards neoplastic transformations are known to affect the morphology of the cell it can be assumed that these deformations can be quantitatively described by means of the cytoskel¬ eton...

From the known statistics of fibre-fibre contacts in random fibre networks, an analytic estimate is obtained for the variance of local porosity in random fibre suspensions and evolving filtrate networks. The variance of local porosity, and hence the distribution of projected areal density, seems to depend on fibre geometry only through the cube of mean diameter. Also, the coefficient of variati...

Spatial structure of genetic variation within populations, an important interacting influence on evolutionary and ecological processes, can be analyzed in detail by using spatial autocorrelation statistics. This paper characterizes the statistical properties of spatial autocorrelation statistics in this context and develops estimators of gene dispersal based on data on standing patterns of gene...

Mobile positioning is recognised to be one of the most promising new sources data for production fast and cost-effective statistics regarding population mobility. Considerable interest has been shown by government institutions in their search a way use mobile produce official statistics, although date there are only few examples successful projects. Apart from access sampling, main challenges r...

In the last few decades, size of spatial and spatio-temporal datasets in many research areas has rapidly increased with development data collection technologies. As a result, classical statistical methods statistics are facing computational challenges. For example, kriging predictor geostatistics becomes prohibitive on traditional hardware architectures for large as it requires high computing p...

In order to opportunistically exploit unused radio spectrum nodes of dynamic spectrum access (DSA) networks monitor the spectrum around them. Such cognitive radios can greatly benefit from a spatial characterization of spectrum use. However, there is need to find an efficient way to describe spatial use, something which has not been studied in details so far. In this paper, we introduce spatial...
