Minimum contradiction matrices are a useful complement to distance-based phylogenies. A minimum contradiction matrix represents phylogenetic information under the form of an ordered distance matrix Y(i) (,) (j) (n). A matrix element corresponds to the distance from a reference vertex n to the path (i, j). For an X-tree or a split network, the minimum contradiction matrix is a Robinson matrix. I...

This paper presents an analysis of contradictions in urban low carbon transitions as engines of change. Following Kojève’s reading of contradiction in Hegel’s oeuvre, I argue that contradiction is a constitutive feature of low carbon interventions. This is an alternative to conventional readings of contradiction as a provisional encounter of opposites in which one will eventually cancel out the...

Analysis of opinions (reviews) generated by users becomes increasingly exploited by a variety of applications. It allows to follow the evolution of the opinions or to carry out investigations on products. The detection of contradictory opinions about a Web resource (e.g., courses, movies, products, etc.) is an important task to evaluate the latter. In this paper, we focus on the problem of dete...

This paper describes (1) the status of the use of biotechnology for conservation and utilization of biodiversity and interaction among them, (2) the status of use of biotechnology for sustainable agriculture, (3) how real are the contradictions among biotechnology, biodiversity and sustainable agriculture , (4) issues and efforts in resolving the concerns and contradictions, and (5) the way ahe...

We demonstrate a contradiction of quantum mechanics with local hidden variable theories for continuous quadrature phase amplitude ~‘‘position’’ and ‘‘momentum’’! measurements. A contradiction is shown possible for two quantum states: a pair-coherent state, and a superpositions of two coherent states, where the superposition state has been squeezed by the action of a two-mode squeezing operator....

The goals of this paper are two-fold: I wish to clarify the Aristotelian conception of the law of non-contradiction as a metaphysical rather than a semantic or logical principle, and to defend the truth of the principle in this sense. First I will explain what it in fact means that the law of non-contradiction is a metaphysical principle. The core idea is that the law of non-contradiction is a ...

We apply to normal logic programs with integrity rules a contradiction removal approach, and use it to uniformly treat diagnosis and debugging, and as a matter of fact envisage programs as artifacts and fault-nding as debugging. Our originality resides in applying to such programs the principle that if an assumption leads to contradiction then it should be revised: assumptions are not A literal...
