Hosts are often infected by a variety of different parasites, leading to competition for hosts and coevolution between parasite species. There is increasing evidence that some vertically transmitted parasitic symbionts may protect their hosts from further infection and that this protection may be an important reason for their persistence in nature. Here, we examine theoretically when protection...

Patterns in nature result from dynamic relationships of forces and constraints. What is analogous for patterns in art? Art is created by human hands motivated by inspiration and thought. It is the product of creativity and skill. Creativity is constrained by cognitive processes and skill by the limits of technology. Based upon the author’s studies of Oriental carpets, this paper suggests that p...

Introduction Measures of farm diversification Data and model specification Econometric results Discussion Summary and conclusions Acknowledgements References Appendix Abstract. Farm planning often focuses on optimal diversification with respect to risk, where the riskmanagement strategies combine production, marketing, financial and environmental aspects of the farmfirm. In this study an empiri...

Incomplete Nature is about an important and difficult subject: how life and mind evolved from a world of inanimate matter. It is also about what are the right concepts to use in understanding the nature and workings of life and mind. We need to be able to conceive them in such a way that it becomes intelligible that they could have arisen naturally from the kinds of inanimate processes describe...

some legal systems recognize a general right to personality from which all concrete rights of personality flow or special laws about some of instances of this right has been adopted. others have developed a wide-ranging protection of personality rights on the basis of general delictual principles. intermixture of intangible rights to personality and human rights arises this question whether for...

A novel method is proposed to retrieve image sequences with the goal of forecasting complex and timevarying natural patterns. To that end, we introduce a framework called Memory-Based Forecasting; it provides forecast information based on the temporal development of past retrieved sequences. This paper targets the radar echo patterns in weather radar images, and aims to realize an image retriev...

Artificially produced chemical elements heavier than uranium have been known for more than seventy years and the number of superheavy elements continues to grow. Presently 26 transuranic elements are known. This paper examines the earliest scientific interest in the very heavy elements and the related question of an upper limit of the periodic system. In the period from the 1880s to the early 1...

Motivations for drawing hierarchical structures are probably as diverse as datasets to visualize. This ubiquity of tree structures has lead to a manifold of tree layout algorithms and tree visualization systems. While many tree layouts exist, increasingly massive data sets, expanding computational power, and still relatively limited display space make tree layout algorithms a topic of ongoing i...

A novel method and a framework called Memory-Based Forecasting are proposed to forecast complex and timevarying natural patterns with the goal of supporting experts’ decision making. This paper targets the local precipitation phenomena captured as echo patterns in weather radar images, and aims to realize a tool that supports weather forecasters. In our framework, past image patterns similar to...
