We present a framework for a declarative approach to spatiotemporal reasoning on geographical data, based on the constraint logical language STACLP, which offers deductive and inductive capabilities. It can be exploited for a deductive rule-based approach to represent domain knowledge on data. Furthermore it is well suited to model trajectories of moving objects, which can be analysed by using ...

Successful honey bee foragers communicate where they have found a good resource with the waggle dance, a symbolic language that encodes a distance and direction. Both of these components are repeated several times (1 to > 100) within the same dance. Additionally, both these components vary within a dance. Here we discuss some causes and consequences of intra-dance and inter-dance angular variat...

A kivo Lenzner, an Estonian professor emeritus of the University of Tartu since 1993 and a well-known researcher of microbial ecology, passed away on 27th of April 2012 at the age of 85. Akivo Lenzner was of Jewish origin, was born in Tartu, and graduated from a high-level Estonian language gymnasium. His father Aron Lenzner had served as a doctor in the Estonian first independence war in 1918Á...

A catastrophe is a type of instability in a simple dynamic system whose unfolding (=evolution) is structurally stable. Examples of commonly experienced catastrophes are sudden changes in a real system, e.g. switches between two states in a buckling plate or the breakdown of stability as in a bridge which collapses. These physical models show the direction for more abstract models as in the case...

This paper addresses two aspects of the Língua Geral Amazônica (LGA). First, we propose that as a technical term in Portuguese was inspired by administrative practices Spain’s American colonies and that, given contemporary usage, should be understood functionally any Tupi-Guarani variety broadly mutually comprehensible with colonial Old Tupi, rather than structurally modified or speech particul...

The disciplines of physiology and ecology are united by the shared centrality of the concept of homeostasis: the stability of a complex system via internal mechanisms of self-regulation, resilient to external perturbation. In the past decade, these fields of study have been bridged by the discovery of the lung microbiome. The respiratory tract, long considered sterile, is in fact a dynamic ecos...
