Nuclear import of proteins with nuclear localization signals (NLSs) is mediated by shuttling carriers, the importins. Some cargoes display more than a single NLS, and among these are homeodomain proteins such as Arx, which is critical for development of multiple tissues. Arx has two functional NLSs. The present studies show that several pathways can import(More)
How has publishing in top economics journals changed since 1970? Using a data set that combines information on all articles published in the top-5 journals from 1970 to 2012 with their Google Scholar citations, we identify nine key trends. First, annual submissions to the top-5 journals nearly doubled from 1990 to 2012. Second, the total number of articles(More)
Importin 13 is a member of the importin beta superfamily of nuclear transport proteins and is expressed in multiple tissues at high levels both in humans and rodents, including fetal lung, brain, and heart. In order to elucidate potential functions of imp13 in the heart, we have used rat imp13 as bait to screen a human heart cDNA library and identified an(More)
Imp13, a member of importin-β superfamily, is found to be one of two bidirectional transport receptors in many nuclear transport activities in mammals. Several cargoes of imp13 have been identified; most of these are essential factors involved in cell cycle and development. The expression and localization of imp13 may influence its cargoes in playing their(More)
Poor readability in concordance result makes the prompt application of corpus in language teaching difficult. This article proposes an adaptive approach to improve concordance readability. The approach, based on the observation that readability is relevant to both text and individual reader, incorporates into the concordance process two types of(More)
Recent DNA sequencing projects and the establishment of high-throughput assays have provided an abundance of sequence information and data on nucleotide polymorphisms in rice. Based on previously identified single-nucleotide polymorphisms (SNPs) and insertions/deletions, we employed denaturing high-performance liquid chromatography (DHPLC) to genotype rice(More)
Academic journals set a variety of policies that affect the supply of new manuscripts. We study the impact of page length policies adopted by the American Economic Review (AER) in 2008 and the Journal of the European Economic Association (JEEA) in 2009, focusing the decision by potential authors to either shorten a longer manuscript, or submit to another(More)
