We had earlier identified the pcnB locus as the gene for the major Escherichia coli poly(A) polymerase (PAP I). In this report, we describe the disruption and identification of a candidate gene for a second poly(A) polymerase (PAP II) by an experimental strategy which was based on the assumption that the viability of E. coli depends on the presence of either PAP I or PAP II. The coding region t...

We test Uncovered Interest Parity (UIP) using LIBOR interest rates for a wide range of maturities. In contrast to other markets, LIBOR markets have minimal frictions which could lead to rejecting UIP. Using panel unit root test suggested by Palm, Smeekes, and Urbain (2010) and cointegration techniques by Westerlund (2007), we find that UIP holds for shortterm maturities, when market-specific he...

Article history: Received 17 April 2012 Received in revised form 11 August 2013 Accepted 12 August 2013 Available online 27 August 2013 By incorporating a keeping-up-with-the-Joneses preference into the Redux model, this paper sketches the implications of consumption externalities for the short-run and long-run equilibria. We show that the size of the consumption externality plays a crucial rol...

PROTEOGLYCANS (PGs) consist of a core protein and linear sugar side chains [glycosaminoglycans (GAGs)] attached to the core protein, e.g., agrin, perlecan, glypican, and syndecan. GAGs comprise repeating duplex sugar units made of an aminosugar (e.g., N-acetylglucosamine or N-acetylgalactosamine) linked to a uronic acid (glucuronic acid or iduronic acid) that are sulfated (3). The sulfate and c...
