Let’s Move Together

Working together to move ahead.

Functional abdominal pain: time to get together and move forward.

Functional gastrointestinal disorders (FGID) include a combination of chronic or recurrent symptoms not explained by known biochemical or structural abnormalities. They represent a challenging group of conditions that are frequently misdiagnosed in children and are associated with significant morbidity and high health care costs. They account for more than 50% of the consultations in pediatric ...

Lets Come Together - Social Navigation Behaviors of Virtual and Real Humans

In this paper, we present a game-like scenario that is based on a model of social group dynamics inspired by theories from the social sciences. The model is augmented by a model of proxemics that simulates the role of distance and spatial orientation in human-human communication. By means of proxemics, a group of human participants may signal other humans whether they welcome new group members ...

Constructability of Trip-lets

A trip-let is an object as shown on the cover of Hofstadter’s book Gödel, Escher, Bach: a solid, threedimensional object that, when viewed from three orthogonal directions, shows three different letters. In this paper we consider two problems related to the construction of such objects for a given set of three letters. First, we want to know whether the silhouettes of the object correspond to t...

On Desugaring Polymorphic Lets

Existing type literature has conflicting views on desugaring polymorphic lets to lambda terms. The conflict arises because, in certain cases, desugaring does not preserve typing. We describe a transformation of polymorphic lets to monomorphic lets such that, when the monomorphic lets are desugared, the typing is preserved. Our transformation requires no changes to either term or type syntax. Th...
