and transport costs can lead to extensive vertical specialization, large trade growth, and large gains from trade. We formally illustrate these points by developing an extension of the Dornbusch-Fischer-Samuelson Ricardian trade model.

points out three causal links: (i) retailers may choose to remain separated to avoid the producer's vertical extension, (ii)

devices. A router configuration is a directed graph with elements at the vertices; packets flow along the edges of the graph. Configurations are written in a declarative language that supports user-defined abstractions. This language is both readable by humans and easily manipulated by tools. We present

We present an object recognition system based on the Dynamic Link Architecture, which is an extension to classical Artificial Neural Networks. The Dynamic Link Architecture ex-ploits correlations in the fine-scale temporal structure of cellular signals in order to group neurons dynamically

that respect the metric of the (possibly weighted) graph. Given a graph G we map its vertices to a normed space in an attempt to (i) Keep down the dimension of the host space and (ii) Guarantee a small distortion, i.e., make sure that distances between vertices in G closely match the dis-tances between

Abstract-An efficient and reliable algorithm for computing the Euclidean distance between a pair of convex sets in Rm is described. Extensive numerical experience with a broad family of polytopes in R3 shows that the computational cost is approximately linear in the total number of vertices

We present extensions to a traditional cellular [Ses95] handoff system to handle the simultaneous operation of multiple wireless network interfaces. This new system allows mobile users to roam in a "Wireless Overlay Network" structure consisting of room-size, building-size, and wide

) and the Predictive Motion Vector Field Adaptive Search Technique (PMVFAST), multihypothesis motion compensation, but also an additional motion classification phase where, depending on the motion of a pixel, additional spatial and temporal information is also considered to further improve performance. Extensive

on the framework of the NCAR MATCH transport model, and can be run using a variety meteorogical input datasets. Surface emissions are based on recent emission inventories. We have extensively evaluated the results of MOZART-2 by comparison with observations. MOZART-2 successfully simulates most features

Drawing on research on range-frequency theory we investigate the effects of price point distance and parent brand's price range on evaluations of vertical extensions. In a series of three experiments we firstly show that price distance has an asymmetric effect of extension evaluation
