Theodora (Theo) Colborn: 1927–2014

Theodora Colborn, research scientist and environmental activist, died 14 December 2014 at the age of 87. As the scientist who coined the term “endocrine disruptor,” Theo—as we had the privilege to call her—played a watershed role in the field of environmental health science, particularly in raising public awareness of the effects of chemical contaminants on human health and the environment. It ...

Quinn Tyler Jackson

Although in the realm of artificial language it is possible to construct languages that do not comprise expressions that are at once both ambiguous and semantically legal, some artificial languages, and all natural languages, present ambiguous constructs that are nonetheless semantically legal expressions accepted by the language. We introduce the §-calculus (meta-S), a declarative adaptive par...

Flatons and Peccei-quinn Symmetry

We study in detail a supersymmetric Peccei-Quinn model, which has a DFSZ and a KSVZ version. The fields breaking the Peccei-Quinn (PQ) symmetry correspond to flat directions (flaton fields) and have unsuppressed couplings when PQ symmetry is unbroken. The models have interesting particle physics phenomenology. The PQ scale is naturally generated through radiative corrections; also, in the DFSZ ...

A Stochastic Jurdjevic--Quinn Theorem

The purpose of this paper is to extend to a ne in the control stochastic di erential systems the well{known result of Jurdjevic{Quinn [2]. This result incorporates a previous result in the stochastic context proved in [1].
