We define analytic torsion τ (X,E ,H) ∈ detH(X, E ,H) for the twisted de Rham complex, consisting of differential forms on a compact Riemannian manifold X valued in a flat vector bundle E , with a differential given by ∇ +H ∧ · , where ∇ is a flat connection on E , H is an odd-degree closed differential form on X, and H(X, E ,H) denotes the cohomology of this Z2-graded complex. We show that whe...

Crafting satisfying narratives while preserving player freedom is a longstanding challenge for computer games. The quest structure used by many games allows players to experience content nonlinearly, but risks creating disjointed stories when side quests only minimally integrate with the main story. We propose a flexible, scene-based emergent story system that reacts to the player’s actions whi...

The hurricane remains one of the outstanding enigmas of fluid dynamics. This is so, in part, because the phenomenon is comparatively difficult to observe and because no laboratory analogue has been discovered. To this it must be added that hurricanes have received surprisingly little attention from the theoretically inclined fluid dynamicist, perhaps owing to an understandable tendency to avoid...

According to Hans Kamp and Frank Vlach, the two-dimensional tense operators “now” and “then” are ineliminable in quantified tense logic. This is often adduced as an argument against tense logic, and in favor of an extensional account that makes use of explicit quantification over times. The aim of this paper is to defend tense logic against this attack. It is shown that “now” and “then” are eli...

In this contribution we propose an analogue receiver that can perform turbo detection inMIMO systems. We present the case for a receiver that is built from nonlinear analogue devices, which perform detection in a “free-flow” network (no notion of iterations). This contribution can be viewed as an extension of analogue turbo decoder concepts to include MIMO detection. These first analogue implem...
