These include human resource planning, recruitment and selection, training and development, reward and motivation, career and succession planning, induction, ...

Handle Atoms with Care

Atoms of a (regular) language L were introduced by Brzozowski and Tamm in 2011 as intersections of complemented and uncomplemented quotients of L. They derived tight upper bounds on the complexity of atoms in 2013. In 2014, Brzozowski and Davies characterized the regular languages meeting these bounds. To achieve these results, they used the so-called “átomaton” of a language, introduced by Brz...

Liquid Biopsies: Handle With Care

Possibly the first mention of the term ‘liquid biopsy’ (as it is understood today) in the scientific literature appears in a report about the 7th International Symposium on Minimal Residual Cancer (ISMRC) held in Athens, Greece in 2009.1 The symposium had focused on, among other things, Circulating Tumor Cells (CTCs) and their relationship to Cancer Stem Cells (CSCs). In that symposium, it was ...

Statistics, Handle with Care: Detecting Multiple Model Components with the Likelihood Ratio Test

The likelihood ratio test (LRT) and the related F-test, popularized in astrophysics by Eadie and coworkers in 1971, Bevington in 1969, Lampton, Margon, & Bowyer, in 1976, Cash in 1979, and Avni in 1978, do not (even asymptotically) adhere to their nominal 2 and F-distributions in many statistical tests common in astrophysics, thereby casting many marginal line or source detections and nondetect...
