Rethinking Set Theory

open access: yesThe American Mathematical Monthly, 2014
Mathematicians manipulate sets with confidence almost every day, rarely making mistakes. Few of us, however, could accurately quote what are often referred to as "the" axioms of set theory. This suggests that we all carry around with us, perhaps subconsciously, a reliable body of operating principles for manipulating sets.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

On Operations over Language Families [PDF]

open access: yesComputer Science Journal of Moldova, 2019
Let $O$ and $\F$ be an operation and a language family, respectively. So far, in terms of closure properties, the classical language theory has only investigated whether $O(\F) \subseteq \F$, where $O(\F)$ is the family resulting from $O$ applied to all ...
