For many years so-called linear models of science, technology and innovation have been used. In essence they reflect sequential processes mostly starting with a science push and ideally ending in an innovatitive product. These models disregard the extreme uncertainties under which innovation-related decisions have to be taken. For that reason a cyc...
The caracteristics of science-linked technologies are investigated by the examples of laser medicine and polyimides in electronics. Different approaches lead to a very comprehensive picture of the examined areas. Especially, a dual model with a distinction between areas of applied and basic research is introduced, and citations to patent and to non...

We look for methods and conditions to make use of cyclicity in some matrix problems, not only for parallel computation but also to reduce the problem size and accelerate convergence. It has been shown that some form of reducibility, not necessarily cyclicity, is enough for such purposes.

The conjectureE(k)⩽k is proved to be true if and only ifk=1, 2, 3, whereE(k) is the cyclicity of condimensionk generic elementary polycycles. It is also proved that the cyclicity of any codimension 3 ensembles except ensembles with “lips” is ⩽6. By the way, the methods usually used in the study of cyclicity of polycycles such as derivation division...

New conditions for a planar homoclinic loop to have cyclicity two under multiple parameter perturbations have been obtained. As an application it is proved that a homoclinic loop of a nongeneric cubic Hamiltonian has cyclicity two under arbitrary quadratic perturbations.

Analysis of the reproductive dynamics ofCalliptamus italicus during the past 100 years confirmed the dependence of locust invasions on the 11-year cycles of solar activity, which was previously known for other gregarious locusts. Over a considerable part of the species range, the onset of mass reproduction is promoted by a hot and droughty spring a...

Common variogram models, such as spherical or exponential functions, increase monotonically with increasing lag distance. On the other hand, a hole-effect variogram typically exhibits sinusoidal waves that form peaks and troughs, thereby conveying the cyclicity of the underlying phenomenon. In order to incorporate this cyclicity into a stochastic s...

Variograms calculated from binary variables, such as from two lithologies, tend to show sinusoidal forms with decreasing amplitudes for increasing lag distances. This cyclicity is observed often when analyzing drill-hole data for rock sequences with alternating lithologies, and the variograms are thus labeled “hole-effect variograms.” Such variogra...
This paper argues for an implementation of cyclicity through a natural economy condition, the Earliness Principle (EP), which requires a feature to be eliminated as early as possible. EP predicts that the search space for feature checking should increase throughout the derivation with the growth of the phrase marker. This prediction is shown to be ...
