We understand a lot about fiber bundle F → E → B, when F is a vector space and the structure group is a linear group. We can compute their cohomology completely. However, if we consider other bundles, such as bundles with fiber F a manifold, where the structure group is the diffeomorphism group, we know nearly nothing at all. In this article, we discuss surface bundles, which is the first step ...

It has been a great honor to represent you dur ing this last year, and it is a great challenge to stand before you now. Table I presents some of the multiple titles I have considered for this pre sentation over the last 10 months. I had a diffi cult time, in early August, when I had to select a final topic and fax my actual title to the Sci entific Program Chair, Bill Petri. I originally though...

The Albany cagera showed that they a r e a team to be reckoned with Monday as they survived a 10 minute period of woeful shooting and miserable passing, and still came on strong at the end to win by 7. The Sauersmen played as well as would be expected for the first 20 minutes, and the Indians from Loudonvllle definitely appeared to be outclassed in almost . all aspects of the game. However, whe...

A large number of patients discuss treatments in online health communities (OHCs). One research question of interest to health researchers is whether treatments being discussed in OHCs are eventually used by community members in their real lives. In this paper, we rely on machine learning methods to automatically identify attributions of mentions of treatments from an online autism community. T...

“All models are wrong but some are useful" [1]. We address the problem of identifying which diagnosis models are more useful than others. Models are critical to diagnostics inference, yet little work exists to be able to compare models. We define the role of models in diagnostics inference, propose metrics for models, and apply these metrics to a tank benchmark system. Given the many approaches...

An analysis of the climate parametrization scheme adopted by conventional forest gap models revealed that most models assume a constant climate and are difficult to calibrate consistently. Tree growth showed unrealistically sensitive threshold effects along ecological gradients of temperature and precipitation. A new parametrization was compared with its predecessors in terms of the model's cap...

Title: Oscillometric measure of blood pressure detects association between orthostatic hypotension and depression in population based study of older adults Author's response to reviews: see over Dear Sir/Madam The authors would like to thank the reviewers for their comments and suggestions with regard to the manuscript entitled 'Oscillometric measure of blood pressure detects association betwee...

BACKGROUND Pay for performance (P4P) schemes have become increasingly popular innovations in primary care and have generated questions about their effect on improving quality of care. AIMS To provide a brief outline of the international evidence on the relationship between P4P schemes and quality improvement. METHOD We conducted a literature search using relevant databases and reference lis...
