This paper describes initial research into the development of an eeective parallel implementation of the direct simulation Monte Carlo (DSMC) method. DSMC is a widely established particle simulation method for the computation of rareeed gas ows, and in many cases is the only eeective means of ow prediction. The method is however computationally expensive in terms of time and memory usage, and f...

Although transnational corporations play the crucial role as transplanters of technology, skills and access to the world market, how they facilitate structural upgrading and economic growth in developing countries has not been adequately conceptualized in terms of a theory of economic development. This article develops a dynamic paradigm o TNC-assisted development by recognizing five key struct...

Joshua Weiner et al. demonstrate that cadherin-related -protocadherins are directly involved in synaptic development. This gene cluster has been suspected to be involved in synaptic specificity, but functional tests of this idea were lacking. Previous research from their group showed that mice lacking the cluster of the three protocadherin (Pcdh) gene clusters ( , , and ) had decreased spinal c...
