Philosophical pleasure canes in about as many shapes and sizes as personal computers do, but one of the keenest pleasures, at least to my way of thinking, is having an article or book actually convince an intelligent reader of an important truth (or at least supposed truth) not previous1y believed. That, however, is as rare as it is satisfying, and anyone who thinks it his/her due dreams, as Sp...

Theoretical accounts of face processing often emphasise feature shapes as the primary visual cue to the recognition of facial expressions. However, changes in facial expression also affect the surface properties of the face. In this study, we investigated whether this surface information can also be used in the recognition of facial expression. First, participants identified facial expressions ...

We show that the families of robustly transitive diffeomorphisms of Mañé and Bonatti–Viana have unique equilibrium states for natural classes of potentials. In particular, for any Hölder continuous potential on the phase space of one of these families, we construct a C-open neighborhood of a diffeomorphism in that family for which the potential has a unique equilibrium state. We also characteri...

Protection buyers share risk with protection sellers, whose assets are only imperfectly pledgeable because of moral hazard. To mitigate moral hazard, privately optimal contracts involve variation margins. When margins are called, protection sellers must sell some of their assets to other investors. We analyse, in a general equilibrium framework, whether this leads to ine¢ cient …re sales. If ma...

“Somebody says, ‘You know, you people always say that space is continuous. How do you know when you get to a small enough dimension that there really are enough points in between, that it isn’t just a lot of dots separated by little distances?’ Or they say, ‘You know those quantum mechanical amplitudes you told me about, they’re so complicated and absurd, what makes you think those are right? M...

The authors retain copyright over this work. This work was presented at the CrossFAB workshop at CHI 2016. Abstract This paper introduces embedded device generation, a design and synthesis process that allows anyone who can write code to develop embedded hardware. The key insight is that a simple program can serve as a complete design specification for the embedded device that runs it. We envis...

This paper considers the relationship between the demographic mechanisms of population control and the energetics of the individuals who comprise the population. We examine the equilibrium properties of a class of structured population models in which individuals compete for some environmental resource (such as food) and demonstrate that population demography is independent of the nature of the...

We consider Bohm's second-order dynamics for arbitrary initial conditions in phase space. In principle, Bohm's dynamics allows for 'extended' non-equilibrium, with initial momenta not equal to the gradient of phase of the wave function (as well as initial positions whose distribution departs from the Born rule). We show that extended non-equilibrium does not relax in general and is in fact unst...

This paper develops a model of an economy with clubs where individuals may belong to multiple clubs and where there may be ever increasing returns to club size. Clubs may be large, as large as the total agent set. The main condition required is that sufficient wealth can compensate for memberships in larger and larger clubs. Notions of price taking equilibrium and the core, both with communicat...
