1 Can RhinOPlaSty Be a 2-StaGe OPeRatiOn? The idea is to inform patients with large noses, especially those with a family background of large noses, of the possibility of 2 stages of surgery. Any operation to reduce the size of the nose substantially can subject the patient to the possibility of pollybeak deformity and disappointment, followed by reconstruction of the nose with a graft, etc. I ...

We investigate the viability of a two-stage inflationary scenario in the context of supergravity, so as to resolve the problem of initial conditions for hybrid inflation. We allow for non-renormalizable terms in the superpotential and consider the most general form of the Kähler potential and the gauge kinetic function. We construct a model with two stages of inflation, the first driven by D-te...

We study the computational complexity of computing a manipulation of a two stage voting rule. An example of a two stage voting rule is Black’s procedure. The first stage of Black’s procedure selects the Condorcet winner if they exist, otherwise the second stage selects the Borda winner. In general, we argue that there is no connection between the computational complexity of manipulating the two...

We develop a two stage model of a manufacturing supply chain. This two stage production transportation model features capacitated production in two stages, and a fixed cost (or concave cost) for transporting the product between the stages. We prove several properties of this model, which we call the Two Stage Production Distribution Problem (2SPDP) model. By placing “non-speculative” assumption...

A typical recognition system consists of a sequential combination of two experts, called a detector and classifier respectively. The two stages are usually designed independently, but we show that this may be suboptimal due to interaction between the stages. In this paper we consider the two stages holistically, as components of a multiple classifier system. This allows for an optimal design th...
