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...

A two-stage method for the computational prediction of the structure of protein-ligand complexes is proposed. Given an experimentally determined structure of the protein, in the first stage a large number of plausible ligand conformations is generated using the fast docking algorithm FlexX. In the second stage these conformations are minimized and reranked using a method based on a classical fo...

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...

Optoelectronic devices such as vertical cavity surface emitting lasers (VCSEL’s) generate large heat power densities on the order of 100’s of Wlcd . A novel device structure consisting of a two-stage monolithically integrated thin film thermionic and thermoelectric cooler is proposed to accommodate these cooling requirements. By optimizing the geometry of each stage, improved heat spreading can...

Testing and deploying mobile wireless networks and applications are very challenging tasks, due to the network size and administration as well as node mobility management. Well known simulation tools provide a more flexible environment but they do not run in real time and they rely on models of the developed system rather than on the system itself. Emulation is a hybrid approach allowing real a...

This paper presents the design and implementation details of an email synthesizer using two-stage stochastic natural language generation, where the first stage structures the emails according to sender style and topic structure, and the second stage synthesizes text content based on the particulars of an email structure element and the goals of a given communication for surface realization. The...

Typical automotive air conditioning refrigeration systems employ thermostatic expansion valve or orifice tube controls in a single stage refrigerant circuit. A new automotive air conditioning compressor has been developed that has a two stage compression process, which makes designing and producing a two stage refrigerant circuit more practical. Since this compressor can function in a single st...

This paper describes the systems with which we participated in the task Sentiment Analysis in Twitter of SEMEVAL 2013 and specifically the Message Polarity Classification. We used a 2-stage pipeline approach employing a linear SVM classifier at each stage and several features including BOW features, POS based features and lexicon based features. We have also experimented with Naive Bayes classi...
