Wireless distributed computing: a survey of research challenges
Datla, Dinesh,Chen, X.,Tsou, T.,Raghunandan, S.,Hasan, S. M. S.,Reed, J. H.,Dietrich, C. B.,Bose, T.,Fette, B.,Kim, J. IEEE 2012 IEEE communications magazine Vol.50 No.1
<P>Recent advancements in radio technology provide great flexibility and enhanced capabilities in executing wireless services. One of these capabilities that can provide significant advantages over traditional approaches is the concept of collaborative computing in wireless networks. With collaborative radio nodes, multiple independent radio nodes operate together to form a wireless distributed computing (WDC) network with significantly increased performance, operating efficiency, and abilities over a single node. WDC exploits wireless connectivity to share processing- intensive tasks among multiple devices. The goals are to reduce per-node and network resource requirements, and enable complex applications not otherwise possible, e.g., image processing in a network of small form factor radio nodes. As discussed in this article, WDC research aims to quantify the benefits of distributed processing over local processing, extend traditional distributed computing (DC) approaches to allow operation in dynamic radio environments, and meet design and implementation challenges unique to WDC with the help of recently available enabling technologies, such as software radios and cognitive radios.</P>

TOP-1β is broadly localized to the nuclei of many cells at all developmental stages and concentrated in nucleoli in embryo gut and oogenic cells. However, TOP-1α is specifically localized to centrosomes, neuronal cells, excretory cells and chromosomes of germ cells in embryonic and larval stages. Reporter gene analysis also shows that <I>top-1</I> transcription is highly activated in several sensory neurons, speculating the possible role of TOP-1α in neuronal development. From RNA interference (RNAi) experiments, we demonstrated that <I>C. elegans</I> TOP-1 is required for chromosomal segregation, germline proliferation and gonadal migration, which are all correlated with the expression and activity of TOP-1. Therefore, our findings may provide an insight into a new role of TOP-1 in development of multicellular organisms.</P>
Intercellular Trafficking of Homeodomain Proteins

Homeotic proteins have pivotal roles during the development of both plant and animals. Many homeotic proteins exert control over cell fate in cells where their genes are not expressed, i.e., in a non-cell autonomous manner. Cell-to-cell communication, which delivers critical information for position-dependent specification of cell fate, is an essential biological process in multicellular organisms. In plants, there are two pathways for intercellular communication that have been identified: the ligand/receptor-mediated apoplastic pathway and the plasmodesmata-mediated symplasmic pathway. Regulatory proteins and RNAs traffic symplasmically via plasmodesmata and play a critical role in intercellular communication. Thus, the non-cell autonomous function of homeotic proteins can be explained by the recent discovery of cell-to-cell trafficking of proteins or RNAs. This article specifically focuses on understanding the intercellular movement of homeodomain proteins, a family of homeotic proteins.

Intercellular signaling is a crucial biological process for the coordination of cell differentiation, organ development and whole plant physiology. The intercellular movement of macromolecule signals such as proteins and RNAs has emerged as a novel mechanism of cell-to-cell communication in plant. Plasmodesmata, which are intercellular symplasmic channels, provide a key pathway for cell-to-cell trafficking of regulatory proteins / RNAs. This review specifically focuses on integrating the recent understanding on non-cell autonomous macromolecules, their function and regulatory mechanisms of intercellular trafficking through plasmodesmata.

<P> Intercellular trafficking of maize KNOTTED1 and its homologous KNOTTED1-related homeobox (KNOX) proteins has been reported; however, little is known about the functional significance of KNOX trafficking in plant development. In this study, we showed that intercellular movement of BREVIPEDICELLUS (BP or KNAT1), the closest Arabidopsis homologue of KNOTTED1, is tissue-specific and takes place through a selective pathway. When BP was fused to a red fluorescent mCherry construct, it could move from the mesophyll to epidermal cells of leaves, although it could not move out from the cortex/endodermis of roots. Using a trichome rescue-trafficking assay, we also showed that BP fusion could confer gain-of-trafficking function to the cell-autonomous GLABROUS1 (GL1) protein. In the wild type, BP transcripts are expressed in the sub-epidermal cortical cell layers of the inflorescence stem and pedicel. However, bp mutant phenotypes include defects in epidermal cell differentiation suggesting a non-cell-autonomous function. Expression of a GFP:BP fusion under the control of a BP promoter specific to the stem cortex layers resulted in epidermal GFP fluorescence suggesting its movement from subepidermis to epidermis. Here, we provide evidence from complementation analyses using cell autonomous or non-cell-autonomous BP fusions that the intercellular trafficking of BP protein is important for plant architecture and epidermal differentiation. </P>
