The number of international migrants in the world increased by 21 million between 1990 and 2000, a 14 percent increase, resulting in 175 million people living in a country outside their birth (United Nations 2002). Remittances from migrants have grown rapidly over the same time, with developing countries receiving $126 billion in 2004 (Ratha 2005). The United States holds the largest stock of i...

Elliptic sheaves (which are related to Drinfeld modules) were introduced by Drinfeld and further studied by Laumon–Rapoport–Stuhler and others. They can be viewed as function field analogues of elliptic curves and hence are objects “of dimension 1”. Their higher dimensional generalizations are called abelian sheaves. In the analogy between function fields and number fields, abelian sheaves are ...

We prove a result involving root systems that implies a converse to Mazur’s inequality for all split groups, conjectured by Kottwitz and Rapoport (see [10]). This was previously known for classical groups (see [11]) and G2 (see [5]).

Anti-miRNA antisense inhibitors (AMOs) have demonstrated their utility in miRNA research and potential in miRNA therapy. Here we report a modified AMO approach in which multiple antisense units are engineered into a single unit that is able to simultaneously silence multiple-target miRNAs, the multiple-target AMO or MTg-AMO. We validated the technique with two separate MTg-AMOs: anti-miR-21/ant...

MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression post-transcriptionally. Previous studies, which characterized miRNA function, revealed their involvement in fundamental biological processes. Importantly, miRNA expression is deregulated in many human diseases. Specific inhibition of miRNAs using chemically modified anti-miRNA oligonucleotides (AMOs) can be a potential th...

Information becomes a more and more valuable asset in today’s organizations. Therefore the need of creating an integrated view over all available data sources arises. Several technical problems must be overcome in the design and implementation of a system for integrating different data sources. To the main obstacles count autonomy, data heterogeneity and different query capabilities of the repo...
