Some examples of non-existent combinators

Non-existent authors.

Authorship of bioscientific papers is a serious business. Most journals have policies that encourage transparency, making it clear who did what, but some authors take it less seriously than editors might like, and indexers don’t always get it right. Searching for common abbreviations (⇓) in PubMed (1809–2017), Embase (1974–2017), Ovid Medline (1946–2017), Philosopher’s Index (1966–2016), and Ps...

Examples of non-quasicommutative semigroups decomposed into unions of groups

Decomposability of an algebraic structure into the union of its sub-structures goes back to G. Scorza's Theorem of 1926 for groups. An analogue of this theorem for rings has been recently studied by A. Lucchini in 2012. On the study of this problem for non-group semigroups, the first attempt is due to Clifford's work of 1961 for the regular semigroups. Since then, N.P. Mukherjee in 1972 studied...

Citation of non-English peer review publications – some Chinese examples

Articles published in English language journals with citations of non-English peer reviewed materials are not very common today. However, as epidemiologists are becoming more aware of data and information being readily available and accessible in the non-English literature, the question of whether non-English materials can be cited in English language journals and if so, how should they be cite...

Monad Combinators, Non-Determinism and Probabilistic Choice

We test Lüth and Ghani’s proposal [11, 12, 13] to use coproducts of monads as a basis for modularity by applying their ideas to Varacca’s work [20] on combining non-determinism and probabilistic choice. In particular, we discuss i) the coproduct of non-determinism and probabilistic choice; ii) how monad compositions based upon distributivity possess a universal property; and iii) Capretta’s [4]...
