In this article we show that hypomorphic loss-of-function alleles of the JIL-1 histone H3S10 kinase are strong suppressors of position effect variegation (PEV) of the wm4 allele and that lack of JIL-1 activity can counteract the effect of the dominant enhancer Evar2-1 on PEV.

In a previous paper (Webster & Wolpert, 1966 a) it was shown that during regulation the time required for the determination of the dominant region, the hypostome, was dependent on the original position of the hypostome-forming region on the linear axis. Hypostome determination occurred more quickly from distal than from proximal regions, suggesting an axial gradient. As Spiegelman (1945) has po...

This paper describes a visual landmark detection and description system for mobile robotic environment mapping. At the detection stage, the proposal employs a perceptual-based hierarchical mechanism which has been previously used to successfully solve the segmentation of natural images. At the description stage, visual landmarks are characterized by a kernel-based representation and by the set ...

Background: Recent studies have revealed that adiponectin, a novel adipocytokine, and its two receptors (AdipoR1 and AdipoR2) are involved in regulation of ovarian function in various farm animal species. The aim of this study was to investigate the gene expression pattern of Adiponectin and its receptors in ovarian cells of dominant (DFs) and non- dominant follicles (NDFs) in the bovine. Mater...

As health care moves to value orientation, radiology's traditional business model faces challenges to adapt. The authors describe a strategic value framework that radiology practices can use to best position themselves in their environments. This simplified construct encourages practices to define their dominant value propositions. There are 3 main value propositions that form a conceptual tria...

Abstract: The online identification of power system dominated inter-area oscillations interface based on the incremental energy function method is proposed in this paper. The dominant inter-area oscillations interface can be obtained by calculating branch oscillation potential energy, which is tie-line concentrated by oscillations energy. To get the oscillation energy caused by the different me...

We investigate the different dominant propagation mechanisms in an urban macroand microcellular base station (BS) installation with a special focus on the application of smart antennas by means of adaptive antenna array measurements. We demonstrate that the congruence of the geometrical mobile station (MS) position and the dominant direction of arrival is only fulfilled for macrocellular BS ins...

Throughout the software products industry, companies everywhere strive for a common goal: to develop and deliver a software product that reaches a dominant position in the marketplace. To achieve this goal, the software team must deliver the right product to the market -one that meets the individual user's needs, has the right features, and delivers the right benefits, including economic advant...
