A shared tenet of embodied, embedded, situated and distributed cognition is that people make sense of things interactively. They run a simulation, they exchange words, often taking turns to change and steer the flow of interaction; they gesture, they handle or manipulate things, they write, sketch or model. Because the concept of interaction seems intuitive, and the phenomena so pervasive, rese...

ion of communication theory as an organising principle for multicellular biology could be realised. We highlight the inherent ability of communication theory to be blind to molecular and/or genetic mechanisms. We describe selected applications that analyse the physics of communication and use energy efficiency as a central tenet. Whilst communication theory has and could contribute to understan...

The management of the liver transplant (OLT) candidate with portopulmonary hypertension (PPHTN) has dramatically changed in the past 3 years. Careful preoperative evaluation with functional characterization of right ventricular function plays a critical role. The pulmonary vascular response to epoprostenol infusion serves as a deciding factor for OLT candidacy. Careful perioperative attention t...

A fundamental tenet of sexual selection is that in sexually dimorphic traits, there is variation within a sex. In leopard geckos (Eublepharis macularius), a species with temperature-dependent sex determination, embryonic temperature contributes both to sex determination and polymorphisms within each sex. In this study we report that males from different incubation temperatures, one hitherto unt...

This article explores effectual processes within home-based online businesses. Our empirical evidence provides a number of refinements to the concept of effectuation in this specific domain. First, the ubiquity of non-proprietary online trading platforms encourages the adoption of effectual approaches and removes the importance of forming proprietary strategic alliances and pre-commitments. Sec...

Many investors believe that they can effectively reduce risk by, among other ways, holding large combinations of investment assets. The purpose of this paper is to develop asymptotic approximations of the windfall and shortfall probabilities for an optimal portfolio of risky assets as the number of the assets becomes sufficiently large. We start by proving general large deviations theorems, the...

ÐWe study implementation issues for spatial convolution filters and their Fourier alternative, with the aim to optimize the accuracy of filter output. We focus on Gaussian scale-space filters and show that there exists a trade-off scale that subdivides the available scale range into two subintervals of equal length. Below this trade-off scale Fourier filtering yields more accurate results than ...

This paper presents the uDSSP (“micro DSSP”) programming model which simplifies the development of distributed sensor network applications that make use of complex in-network processing. Using uDSSP, an application is composed of state-centric services. These services interact by accessing the state of other services or by subscribing to changes of that state. uDSSP supports heterogeneous netwo...

This paper investigates the question of whether Krivine’s classical realizability can provide a verificationist interpretation of classical logic. We argue that this kind of realizability can be considered an adequate candidate for this semantic role, provided that the notion of verification involved is no longer based on proofs, but on programs. On this basis, we show that a special reading of...

When thinking about the course “birational geometry for number theorists” I so näıvely agreed to give at the Göttingen summer school, I could not avoid imagining the spirit of the late Serge Lang, not so quietly beseeching one to do things right, keeping the theorems functorial with respect to ideas, and definitions natural. But most important is the fundamental tenet of Diophantine geometry, f...
