When working with groups of robots it may be very difficult to determine what characteristics the group requires in order to perform a task most efficiently-i.e., in the least time. Some researchers have used groups of behaviorally differentiated robots-where the robots do not perform the same actions-and others have used behaviorally homogeneous groups. None of this research, however, explicit...

The RNA-binding protein hnRNP Q has been implicated in neuronal mRNA metabolism. Here, we show that knockdown of hnRNP Q increased neurite complexity in cultured rat cortical neurons and induced filopodium formation in mouse neuroblastoma cells. Reexpression of hnRNP Q1 in hnRNP Q-depleted cells abrogated the morphological changes of neurites, indicating a specific role for hnRNP Q1 in neuronal...

The ultrastructural distribution of nuclear ribonucleoproteins (RNP) within spread active chromatin has been investigated using specific anti-RNP antibodies. Monoclonal antibodies directed against the core proteins of heterogeneous nuclear (hn)RNP or against small nuclear (sn)RNP have been incubated directly with lysed mouse or Drosophila tissue culture cells and the bound antibodies visualized...

An important emerging theme is that heterogeneous nuclear ribonucleoproteins (hnRNPs) not only function in the nucleus but also control the fates of mRNAs in the cytoplasm. Here, we show that hnRNP D plays a versatile role in cytoplasmic mRNA turnover by functioning as a negative regulator in an isoform-specific and cell-type-dependent manner. We found that hnRNP D discriminates among the three...

This paper describes an approach of how to support collaborative modelling tasks. The presented system, Cool Modes, implements the approach using “plug-in” reference frames encapsulating the semantics of the used models. Details on the extensibility of the system and the definition and interpretation of these reference frames and models in the framework are shown and the co-operation support us...

Decision processes for solving group decision making problems are composed of two phases: (i) aggregation and, (ii) exploitation. When experts that participate in the group decision making process are not able to express their opinions using a same expression domain, then the use of information assessed in different domains, i.e., heterogeneous information, is necessary. In these cases, the inf...

idiopathic hypereosinophilic syndrome represents a heterogeneous group of leukoprolifrative disorders associated with prolonged eosinophilia of an undetectable cause with multi organ system dysfunction. it is a rare group disorder in children, most cases are reported in adult age group. we report a child with this syndrome who along with the usual features of the syndrome also had the presentat...
