TL;DR: This framework fundamentally extends previous work on shape priors in level set segmentation by directly addressing the central question of where to apply which prior and may selectively use specific shape knowledge for simultaneously enhancing segmentation and recognizing shape.
Abstract: We propose a variational framework for the integration of multiple competing shape priors into level set based segmentation schemes. By optimizing an appropriate cost functional with respect to both a level set function and a (vector-valued) labeling function, we jointly generate a segmentation (by the level set function) and a recognition-driven partition of the image domain (by the labeling function) which indicates where to enforce certain shape priors. Our framework fundamentally extends previous work on shape priors in level set segmentation by directly addressing the central question of where to apply which prior. It allows for the seamless integration of numerous shape priors such that--while segmenting both multiple known and unknown objects--the level set process may selectively use specific shape knowledge for simultaneously enhancing segmentation and recognizing shape.

01 Jan 2000TL;DR: For arbitrary compact quantizable Kahler manifolds, a natural formal deformation quantization (star-product) can be obtained via Berezin-Toeplitz operators as discussed by the authors.
Abstract: For arbitrary compact quantizable Kahler manifolds it is shown how a natural formal deformation quantization (star-product) can be obtained via Berezin-Toeplitz operators. Results on their semi-classical behaviour (their asymptotic expansion) due to Bordemann, Meinrenken, and Schlichenmaier are used in an essential manner. It is shown that the star-product is null on constants and fulfills parity. A trace is constructed and the relation to deformation quantization by geometric quantization is given.

TL;DR: The authors construct a life cycle model that delivers realistic behavior for both equity holdings and borrowing, where the key model ingredient is a wedge between the cost of borrowing and the risk-free investment return.
Abstract: We construct a life cycle model that delivers realistic behavior for both equity holdings and borrowing. The key model ingredient is a wedge between the cost of borrowing and the risk-free investment return. Borrowing can either raise or lower equity demand, depending on the cost of borrowing. A borrowing rate equal to the expected return on equity—which we show roughly matches the data—minimizes the demand for equity. Alternative models with no borrowing or limited borrowing at the risk-free rate cannot simultaneously fit empirical evidence on borrowing and equity holdings.

TL;DR: In this paper, the authors consider a setting where several privately informed agents bid for a price and all bidders bear a cost of bidding that is an increasing function of their bids, and moreover, bids may be capped.
Abstract: We study contests where several privately informed agents bid for a price. All bidders bear a cost of bidding that is an increasing function of their bids, and, moreover, bids may be capped. We show that, regardless of the number of bidders, if agents have linear or concave cost functions then setting a bid cap is not profitable for a designer who wishes to maximize the average bid. On the other hand, if agents have convex cost functions (i.e. an increasing marginal cost) then affectively capping the bids is profitable for a designer facing a sufficiently large number of bidders.

TL;DR: In this article, an intergroup randomized trial of adjuvant imatinib versus no further therapy after R0-R1 surgery patients with localized, high- or intermediate-risk GI stromal tumor (GIST) was conducted.
Abstract: Purpose In 2004, we started an intergroup randomized trial of adjuvant imatinib versus no further therapy after R0-R1 surgery patients with localized, high- or intermediate-risk GI stromal tumor (GIST). Patients and Methods Patients were randomly assigned to 2 years of imatinib 400 mg daily or no further therapy after surgery. The primary end point was overall survival; relapse-free survival (RFS), relapse-free interval, and toxicity were secondary end points. In 2009, given the concurrent improvement in prognosis of patients with advanced GIST, we changed the primary end point to imatinib failure–free survival (IFFS), with agreement of the independent data monitoring committee. We report on a planned interim analysis. Results A total of 908 patients were randomly assigned between December 2004 and October 2008: 454 to imatinib and 454 to observation. Of these, 835 patients were eligible. With a median follow-up of 4.7 years, 5-year IFFS was 87% in the imatinib arm versus 84% in the control arm (hazard ra...
