Metabolomics cuts to the chase to chase the cuts.

type II diabetes5. However, like most proteases, a complete picture of the targets of DPP4 is lacking, which makes it difficult to anticipate metabolic function has prompted the development of a number of small-molecule inhibitors of DPP4, including sitagliptin (Januvia), which was recently approved by the US Food Proteases are enzymes that perform the basic task of cutting up other proteins an...

On Regular Reduced Products

Assume 〈א0,א1〉 → 〈λ, λ +〉. Assume M is a model of a first order theory T of cardinality at most λ+ in a vocabulary L(T ) of cardinality ≤ λ. Let N be a model with the same vocabulary. Let ∆ be a set of first order formulas in L(T ) and let D be a regular filter on λ. Then M is ∆-embeddable into the reduced power N /D, provided that every ∆-existential formula true in M is true also in N . We ob...

Stop the Chase

The chase procedure, an algorithm proposed 25+ years ago to fix constraint violations in database instances, has been successfully applied in a variety of contexts, such as query optimization, data exchange, and data integration. Its practicability, however, is limited by the fact that – for an arbitrary set of constraints – it might not terminate; even worse, chase termination is an undecidabl...

The electronic paper chase.

RELATED LINKS It offers excellent resolution and high contrast under a wide range of viewing angles, requires no external power to retain its image, weighs little, costs less and is remarkably flexible (literally and figuratively)-unlike today's computer displays. No wonder traditional ink on paper continues to flourish in a digital world that was expected to all but do away with it. Yet ink on...

The radical cation of syn-tricyclooctadiene and its rearrangement products

The syn dimer of cyclobutadiene (tricyclo[4.2.0.0(2.5)]octa-3,7-diene, TOD) is subjected to ionization under different conditions and the resulting species are probed by optical and ESR spectroscopy. By means of quantum chemical modelling of the potential energy surfaces and the optical spectra, it is possible to assign the different products that arise spontaneously after ionization or after s...
