Rheumatic Pains: Some Concepts and Hypotheses

Formalizing Hypotheses with Concepts

The frequently used strategy of forming hypotheses, based on observations, to generate predictions can be formalized in several ways. We study an elaborated approach that has some conceptual flavour and translate the basic ideas in the language of Formal Concept Analysis, blazing the trail for applications to other conceptual structures as well. We investigate the relation to pseudo intents, di...

A Review of Some Hypotheses

Barcoding a Quantified Food Web: Crypsis, Concepts, Ecology and Hypotheses

The efficient and effective monitoring of individuals and populations is critically dependent on correct species identification. While this point may seem obvious, identifying the majority of the more than 100 natural enemies involved in the spruce budworm (Choristoneura fumiferana--SBW) food web remains a non-trivial endeavor. Insect parasitoids play a major role in the processes governing the...
