In the influential paper in which he proved that every graph with m edges can be embedded in a book with O(m1/2) pages, Malitz proved the existence of d-regular n-vertex graphs that require Ω(n 1 2 − 1 d ) pages. In view of the O(m1/2) bound, this last bound is tight when d > log n, and Malitz asked if it is also tight when d < log n. We answer negatively to this question, by showing that there...

This paper describes the work of the LaHC lab of SaintÉtienne for the Social Book Search lab at CLEF 2015. Our goals were i) to study a field-based retrieval model (BM25F), exploiting various topics and documents fields, in order to build a strong baseline for further experiments, ii) to compare it with a Log logistic (LGD) retrieval model, and iii) to exploit some documents related to each top...

This paper explores the ability of theoretically-based asset pricing models such as the CAPM and the consumption CAPM referred to jointly as the (C)CAPM to explain the cross-section of average stock returns. Unlike many previous empirical tests of the (C)CAPM, we specify the pricing kernel as a conditional linear factor model, as would be expected if risk premia vary over time. Central to our a...

Social networking sites supporting federated identities offer a convenient and increasingly popular mechanism for cross-site authentication. Unfortunately, they also exacerbate many privacy and tracking risks. We propose Crypto-Book, an anonymizing layer enabling cross-site authentication while reducing these risks. Crypto-Book relies on a set of independently managed servers that collectively ...
