BACKGROUND SEN virus is a blood-borne, single-stranded, nonenveloped DNA virus. Two of its strains (D and H), appear to be associated with non-A-to-E hepatitis more frequently than the others, although it is not clear whether this observation has any significance. The prevalence of SEN virus in otherwise healthy individuals, including blood donors, differs markedly by geographic region. In this...

In the transmissible spongiform encephalopathies, normal prion protein (PrP-sen) is converted to a protease-resistant isoform, PrP-res, by an apparent self-propagating activity of the latter. Here we describe new, more physiological cell-free systems for analyzing the initial binding and subsequent conversion reactions between PrP-sen and PrP-res. These systems allowed the use of antibodies to ...

We study equational axiomatizations of bisimulation equivalence for the language obtained by extending Milner's basic CCS with string iteration. String iteration is a variation on the original binary version of the Kleene star operation p q obtained by restricting the rst argument to be a non-empty sequence of atomic actions. We show that, for every positive integer k, bisimulation equivalence ...

In this paper I maintain that Amartya Sen’s Capability Approach (CA) implies a recuperation of practical science in Economics. Sen’s proposal has some problems closely related to this practical character: the heterogeneity and incommensurability of capabilities, its ambiguity concerning the use of the term “capability”, and the consequent lack of operative character of the CA. Sen recognizes th...

BACKGROUND Short bowel syndrome (SBS) can lead to intestinal failure and require total or supplemental parenteral nutrition (TPN or PN, respectively). Glucagon-like peptide 2 (GLP-2) is a nutrient-dependent, proglucagon-derived gut hormone that stimulates intestinal adaptation. OBJECTIVE Our objective was to determine whether supplemental enteral nutrients (SEN) modulate the intestinotrophic ...

The use of computational steering for smog prediction is described. This application is representative for many underlying issues found in steering high performance applications: high computing times, large data sets, and many diierent input parameters. After a short description of the smog prediction model, its visualization and steering are described. The amount of computation needed to solve...

Computational steering is a technique that combines simulation and visualization. The user is continuously provided with visual feedback about the state of the simulation, and can change parameters on the y. Designers can vary parameters to optimize their product, users can detect errors in the input early, researchers can do qualitative sensitivity analyses easily. The implementation of comput...

We present a method for the deenition of multiple views in 3D interfaces for computational steering. The method uses the concept of a point-based parametrizable camera object. This concept enables a user to create and conngure multiple views on his custom 3D interface in an intuitive graphical manner. Each view can be coupled to objects present in the interface, parametrized to (simulation) dat...
