Recent work by Jaffe and Scardicchio has expressed the optical approximation to the Casimir effect as a sum over geometric quantities. The first two authors have developed a technique which uses the complex geometry of the space of oriented affine lines in R to describe reflection of rays off a surface. This allows the quantities in the optical approximation to the Casimir effect to be calculat...

TO THE EDITOR—We are pleased that our article prompted discussion on the path-ogenesis of bacterial vaginosis (BV) [1]. As a conceptual model with testable hypotheses , this was exactly what we had hoped for, to continue the dialogue on an important topic that has been stagnant until the recent emergence of new work on Gardnerella vaginalis from various investigators. As Hickey and Forney point...

We thank Hickey et al. [1] for their insightful comments with regard to our validation study on EuroSCORE II [2]. With regard to the era of patients, a time bias almost certainly does exist. This is a limitation of many retrospective singleinstitution validation studies, as most units do not have the number, and thus the statistical power, to use a small reference time period. It has already be...

It has come to our attention that there appears to be an error in the recent article by Nashef et al. [1].

However, in Table 7, it states that the Hosmer–Lemeshow test was applied to 15 952 records (of which 605 died). A reader might conclude tha...

The first of the two sentences in (1) entails the second; necessarily, if the first is true then so is the second. Moreover, (1) is an instance of a more general pattern whose validity doesn’t seem to depend on the specific meanings of the words in (1). The adverb ‘quickly’, for example, can be replaced with any of a wide range of adverbs without loss of validity; analogous remarks hold for the...
