Ejaculate volume and sex ratios were checked for correlations in the red millipede genus Centrobolus. There was a significant relationship between ejaculate volumes and sex ratio (Kendall's τ: r=-0.27854301, Z score=-120000, n=8, p=0). This suggests the pattern of mate guarding was positively associated with ejaculate volume and the intensity of in...

This paper provides a comprehensive cross-linguistic overview of over-counting, whereby a target numeral is expressed by counting toward the next-higher multiple of the base. I identify three major morphological patterns in overcounting numerals: P-connector, V-connector and no overt connector. I then zoom in on the structure of overcounting numera...

We report the existence of deterministic patterns in statistical plots of single-cell transcriptomic data. We develop a theory showing that the patterns are neither artifacts introduced by the measurement process nor due to underlying biological mechanisms. Rather they naturally emerge from finite sample size effects. The theory precisely predicts...

The problem of finding the cardinality of various avoidance classes of C_n has been an ongoing object of study, and members of C_n avoiding one or two cla...

The symmetry aspects of close packing of hexagonal layers of equal spheres are usually presented with reference to the two basic patterns: AB… (P63/mmc) and ABC… (Fm3m), of which the latter is the fundament of the Kepler conjecture, published in 1611, stating that no arrangement of equal spheres can achieve higher density. In fact, however, there a...

It is well known that the number of 123-avoiding and 321-avoiding permutations is the same, and these numbers correspond to the Catalan numbers. However, patterns 123 and 321 are not equidistributed. In the context of mesh patterns, patterns formed by the permutations 123 and 321 with identical shadings are sometimes jointly equidistributed. In thi...
