Methotrexate for the Treatment of Crohn's Disease

Abstract: Background Although corticosteroids are highly effective in improving symptoms of Crohn's disease, they may have substantial toxicity. In some patients, attempts to discontinue corticosteroids are ...

Surface terms as counterterms in the AdS-CFT correspondence

Abstract: We examine the recently proposed technique of adding boundary counterterms to the gravitational action for spacetimes which are locally asymptotic to anti--de Sitter spacetimes. In particular, we explicitly identify higher order counterterms, which allow us to consider spacetimes of dimensions $dl~7.$ As the counterterms eliminate the need of ``background subtraction'' in calculating the action, we apply this technique to study examples where the appropriate background was ambiguous or unknown: topological black holes, Taub-NUT-AdS and Taub-Bolt-AdS. We also identify certain cases where the covariant counterterms fail to render the action finite, and we comment on the dual field theory interpretation of this result. In some examples, the case of a vanishing cosmological constant may be recovered in a limit, which allows us to check results and resolve ambiguities in certain asymptotically flat spacetime computations in the literature.

How NOT To Evaluate Your Dialogue System: An Empirical Study of Unsupervised Evaluation Metrics for Dialogue Response Generation

Abstract: We investigate evaluation metrics for dialogue response generation systems where supervised labels, such as task completion, are not available. Recent works in response generation have adopted metrics from machine translation to compare a model's generated response to a single target response. We show that these metrics correlate very weakly with human judgements in the non-technical Twitter domain, and not at all in the technical Ubuntu domain. We provide quantitative and qualitative results highlighting specific weaknesses in existing metrics, and provide recommendations for future development of better automatic evaluation metrics for dialogue systems.

The Architecture of Simplicity

Abstract: This article argues that over time the world views, goals, strategies, cultures, and processes of successful organizations will become more pure or “simple”: They will come to focus more narrowly on a single theme, activity, or issue at the expense of all others. This is explained by managerial, cultural, structural, and process factors within the organization. It is also attributed to both the complementary way in which these factors configure and the paradox that although simplicity may trigger ultimate failure, it can bring about Initial success. The article offers some illustrative propositions concerning the nature, causes, moderating factors, and consequences of simplicity, and it makes suggestions for conducting further research.
