With their application as seed coatings, the use of neonicotinoid insecticides increased dramatically during the last decade. They are now frequently detected in aquatic ecosystems at concentrations susceptible to harm aquatic invertebrates at individual and population levels. This study intent was to document surface runoff and subsurface tile drain losses of two common neonicotinoids (thiamet...

Tile logic is a framework to reason about the dynamic evolution of concurrent systems in a modular way, and it extends rewriting logic (in the unconditional case) by rewriting synchronization and side eeects. The subject of this dissertation concerns some interesting tile models of computation such that the mathematical structures representing conngurations (i.e., system states) and eeects (i.e...

Applying non-photorealistic rendering techniques to stylise portraits needs to be done with care, as facial artifacts are particularly disagreeable. This paper describes a technique for watercolour rendering that uses a facial model to preserve distinctive facial characteristics and reduce unpleasing distortions of the face, while maintaining abstraction and stylisation of the overall image, em...

In this work we propose a generalization of Winfree’s abstract Tile Assembly Model (aTAM) in which tile types are assigned rigid shapes, or geometries, along each tile face. We examine the number of distinct tile types needed to assemble shapes within this model, the temperature required for efficient assembly, and the problem of designing compact geometric faces to meet given compatibility spe...

BACKGROUND Pelvic fractures are severe injuries with frequently associated multi-system trauma and a high mortality rate. The value of the pelvic fracture pattern for predicting transfusion requirements and mortality is not entirely clear. To address hemorrhage from pelvic injuries, the early application of pelvic binders is now recommended and arterial angio-embolization is widely used for con...

An aperiodic tile set is a finite set of tiles which can tile the plane (i.e. cover it without overlap), but not in a periodic way (i.e., no tiling is invariant by a translation). To prove the undecidability of the the Domino problem, Robert Berger constructed in 1966 the first aperiodic tile set [1]. His proof was simplified in 1971 by Rafael Robinson, who introduced a six-tile set and proved ...
