We explore the halo structure of four gravitational lenses with well-observed, thin Einstein rings. We find that the gravitational potentials are well described by ellipsoidal density distributions in the sense that the best-fit nonellipsoidal models have parameters consistent with their ellipsoidal counterparts. We find upper limits on the standard parameters for the deviation from an ellipse ...

This paper studies a moral hazard problem in which the agent can borrow on future wages before undertaking a costly e¤ort. The game between the agent and potential lenders is modelled as an in…nite stochastic game with an exogenous stopping probability. It is shown that regardless of the initial wage contract the agent sequentially enters into multiple borrowing agreements which dilute e¤ort in...

OBJECTIVE The direct trocar technique is an alternative to Veress needle insertion and open laparoscopy for accessing the abdominal cavity for operative laparoscopy. We review our approach to abdominal entry in 1385 laparoscopies performed between September 1993 and June 2000 by our group at Stanford University Hospital, a tertiary Medical Center. METHODS We performed a retrospective chart re...

This is the first deliverable under work package WP1 of the HYBRIDGE project. The aim of the report is to provide a list of safety critical operational situations in air traffic management. A “gate to gate” view is presented of the safety critical situations an aircraft may encounter in normal flight conditions. Particular attention is devoted to cases likely to become more prominent as air tra...

An artificial neural network has been used to model the irradiation hardening of lowactivation ferritic/martensitic steels. The data used to create the model span a range of displacement damage of 0 90 dpa, within a temperature range of 273 973 K and contain 1800 points. The trained model has been able to capture the non-linear dependence of yield strength on the chemical composition and irradi...
