This work discusses three aspects of net theory: compositionality of nets, analysis of nets and high-level nets. Net theory has often been criticised for the diiculty of giving a compositional semantics to a net. In this work we discuss this problem form a category theoretic point of view. In category theory compositionality is represented by colimits. We show how a high-level net can be mapped...

Genomic DNA sequences display compositional heterogeneity on many scales. In this paper we analyzed tendencies and anomalies in the occurence of mono, di and trinucleotides in structural regions of plant genes. Representation of these trends as a function of position along genic sequences highlighted compositional features peculiar of either monocots or eudicots that were remarkably uniform wit...

Composition technologies improve reuse in the development of large-scale complex systems. Safety critical systems require intensive validation and verification activities. These activities should be compositional in order to reduce the amount of residual verification activities that must be conducted on the composite in addition to the ones conducted on each components. In order to ensure the c...

Simpson’s paradox, also known as amalgamation or aggregation paradox, appears when dealing with proportions. Proportions are by construction parts of a whole, which can be interpreted as compositions assuming they only carry relative information. The Aitchison inner product space structure of the simplex, the sample space of compositions, explains the appearance of the paradox, given that amalg...

This paper is motivated by the recent interest in the analysis of high dimensional microbiome data. A key feature of this data is the presence of ‘structural zeros’ which are microbes missing from an observation vector due to an underlying biological process and not due to error in measurement. Typical notions of missingness are insufficient to model these structural zeros. We define a general ...

The efficiency of the boron (B) nutritional status in soybean (Glycine max (L.) Merr.) was evaluated by degree agreement (DA) indicators using different diagnostic methods and prescient analysis (PDA). objective this study to evaluate two interpretation B soybean, that is, compositional nutrient diagnosis (CND) critical level (CL). An experimental trial conducted a randomized block design with ...
