Problem statement: The heterogeneity in the choice of simulation platforms for real time scheduling stands behind the difficulty of developing a common simulation environment. A Discrete Event Simulation (DES) for a real time scheduling domain encompassing event definition, time advancing mechanism and scheduler has yet to be developed. Approach: The study focused on the proposed and the develo...

The 5'-untranslated leader sequences of several plant RNA viruses, and a portion of the 5'-leader of an animal retrovirus, were tested for their ability to enhance expression of contiguous open reading frames for chloramphenicol acetyltransferase (CAT) or beta-glucuronidase (GUS) in tobacco mesophyll protoplasts, Escherichia coli and oocytes of Xenopus laevis. Translation of capped or uncapped ...

The pool of tubulin protein in tissues of Arabidopsis is provided by the expression of multiple alpha-tubulin (TUA) and beta-tubulin genes. Whereas most tubulin genes are expressed in many tissues, previous evidence suggested that the TUA1 gene might be expressed primarily in pollen. We now report a detailed analysis of TUA1 expression during Arabidopsis development. In RNA from tissues of diss...

In one of 30 transgenic tobacco (Nicotiana tabacum) plants, the expression of an introduced beta-glucuronidase (GUS) gene driven by the cauliflower mosaic virus 35S promoter, was found to be repressed as the plant matured, whereas the endogenous GUS activity was unaffected. Plants grown from seeds or regenerated from leaf discs derived from this plant showed a similar temporal pattern of expres...

To study whether DNA pairing that influences gene expression can take place in somatic plant cells, a system designed to mimic transvection was established in transgenic tobacco. Pairing was evaluated by testing whether an enhancerless GUS gene on one allele could be activated in trans by an enhancer on the second allele. The required heteroalleles were obtained at four genomic locations using ...

A stable Agrobacterium-mediated transformation system was established using bialaphos as the selective agent in soybeans [Glycine max (L.) Merr.]. The cotyledonary node explants of the soybean cultivar ‘NY-1001’ were inoculated with the Agrobacterium tumefaciens strain EHA105, harboring the vector pCAMBIA3301 containing the gus gene as the reporter gene and the bar gene conferring bialaphos res...

The role of resistance (R) genes in plant pathogen interaction has been studied extensively due to its economical impact on agriculture. Interaction between tobacco mosaic virus (TMV) and the N protein from tobacco is one of the most widely used models to understand various aspects of pathogen resistance. The transcription activity governed by N gene promoter is one of the least understood elem...

Fragile X tremor ataxia syndrome (FXTAS) is a late-onset disorder manifesting in a proportion of FMR1 premutation individuals (PM: 55-199 CGG triplet expansions). FXTAS is associated with elevated levels of FMR1 mRNA which are toxic. In this study, relationships between neurocognitive and intra-step gait variability measures with mRNA levels, measured in blood samples, were examined in 35 PM an...

Transient expression profiles for several chimeric beta-glucuronidase (GUS) gene constructs were determined in tissues (young leaves, mature leaves and roots) of creeping bentgrass (Agrostis palustris, cv. Penn A4) following microprojectile bombardment. The constructs analyzed consisted of the uidA (GUS) reporter gene driven by four different promoters (ubiquitin 3-potato, ubiquitin corn, ubiqu...

In this letter, we study the deployment of Unmanned Aerial Vehicle mounted Base Stations (UAV-BSs) in multi-UAV cellular networks. We model problem as a user satisfaction maximization problem, that is, maximizing proportion served ground users (GUs) meet given minimum data rate requirement. propose an interference-aware (IAD) algorithm for serving arbitrarily distributed outdoor GUs. The propos...
