Decidability Problems for Actor Systems [PDF]
Logical Methods in Computer Science, 2014 We introduce a nominal actor-based language and study its expressive power. We have identified the presence/absence of fields as a crucial feature: the dynamic creation of names in combination with fields gives rise to Turing completeness.

Roadsides and neighboring field edges harbor different weed compositions
Frontiers in Agronomy, 2022 Roadsides are vectors of spread for invasive and other non-native plants. Therefore, fields located along roadsides could harbour more weeds and less native species compared to more isolated fields. To determine if field edges that are close to roadsides

The Professional Landscape: The Historical Development of Professions in Sweden
Professions and Professionalism, 2013 This special issue of Professions & Professionalism seeks to explain the transition of occupations from non-professions to professions and the conditions and causes that generate professions (i.e., the bases of professionalization).

Manuscripta Mathematica, 1992 The author extends Hasse's classical class number formula for biquadratic number fields to biquadratic dicyclic extensions over a totally real base field, which has odd class number, only one dyadic prime and units with independent signs. The proofs use the cohomological device of the ``exact hexagon'' developed by \textit{P. E.

, 2022 Associated to an open subgroup $G$ of $\GL_2(\Zhat)$ satisfying conditions $-I \in G$ and $\det(G) \subsetneq (\Zhat)^{\times}$ there is a modular curve $X_G$ which is a smooth compact curve defined over an extension of $\Q.$ In this article, we give a complete list of all such prime power level genus $0$ modular curves with a point.
