To learn how well ungapped sequence comparisons of multiple species can predict cis-regulatory elements in Caenorhabditis elegans, we made such predictions across the large, complex ceh-13/lin-39 locus and tested them transgenically. We also examined how prediction quality varied with different genomes and parameters in our comparisons. Specifically, we sequenced approximately 0.5% of the C. br...

The purpose of this paper is to present a framework for the empirical analysis of price and quality choice by a multiproduct monopolist. We do so by demonstrating that well-known techniques from the optimal screening literature used in the theoretical analysis of nonlinear pricing map naturally to the empirical analysis of di erentiated product markets. We then apply a generalized one-dimension...

background: musa creek, suitable place for spawning of many fish species and other organisms, is one of the most important and voluble ecosystems in the west of iran that received so many attentions due to existents of various industries around this part of persian gulf. previous studies confirmed that marine fish have collected high amounts of pollutants in this area which could be lead to sev...

background: determination of digestive enzymes activity would provide critical information in the design of appropriate diet. sobaity, sparidentex hasta is found in the persian gulf and  cultured in countries adjacent to it. objectives: this study investigated proteolytic, amylase and lipase activities in the intestine of sparidentex hasta captured from the  persian gulf. methods: 60 immature s...

 The present work has been carried out to investigate the probable effects of fish cage culture on benthic communities as a pollution and stress indicator and to evaluate the biotic health condition using BOPA index, in Ghazale Creek (Khowre-Mussa - Persian Gulf). Monthly sampling from 4 stations was carried out from June 2007 to March 2008 (during nine months). Stations were selected from unde...

In laboratory settings, motor learning has typically been studied in the context of adaptation paradigms in which subjects must learn to compensate for a systematic perturbation—either some manipulation of visual feedback (Krakauer et al. 2000) or a change in the dynamics of the motor apparatus, e.g., a force applied to the hand (Shadmehr and Mussa-Ivaldi 1994), Coriolis forces induced by rotat...

Economic models for hedonic markets characterize the pricing of bundles of attributes and the demand and supply of these attributes under different assumptions about market structure, preferences, and technology (see Jan Tinbergen [1956], Sherwin Rosen [1974], and Dennis Epple [1987] for contributions to this literature). While the theory is well formulated and delivers some elegant analytical ...

This chapter is concerned with modeling the economic linkages among countries. Although there are by now a number of multicountry macroeconometric models in existence, it seems safe to say with respect to the treatment of capital Rows and exchange rates that econometric work has not kept pace with theoretical developments. Since Mundell’s pioneering theoretical work (1968) in the 1960s. the pot...

Introduction Since the inauguration of modern, general equilibrium analysis of smuggling by Bhagwati and Hansen (1973), the standard framework for analysis has been some version of the Hecksher-Ohlin-Samuelson (HOS) model. Moreover, with the notable exception of Sheikh (1974), the standard framework depicts smuggling as an activity that uses no domestic resources. In this article we alter the s...
