Mechanisms of bullseye boundary formation in Hibiscus trionum petal patterning
… model system producing flowers with a striking bullseye pattern on the adaxial petal epidermis. Cells in the proximal region are flat, elongated with cuticular striations and accumulate purple anthocyanin pigments, while cells in the distal region are white, conical and smooth. However, the …

Understanding the development, evolution, and function of bullseye pigmentation patterns in Hibiscus trionum
… the development, evolution, and function of the bullseye pigmentation pattern on Hibiscus trionum petals. The bi-coloured bullseye pattern of H.trionum is created from contrast in cell shape, cuticle texture, and pigmentation between the bottom and top of the petal. The bottom petal appears shiny …

Hitting the Bullseye: The Influence of Technical Debt on the Accuracy of Effort Estimation in Agile Projects
As firms rapidly develop solutions in order to increase revenue and market share, software development decisions considered to be temporary shortcuts and/or compromises may be implemented. These shortcuts represent “technical debt,” a metaphor which succinctly describes a software solution that …

Flavonoid diversification in Hibiscus and its impact on petal pattern evolution
… In Hibiscus trionum, a new model system, bullseye patterns are formed by flavonoid pigments including anthocyanins and flavonols. Their flowers display a contrast between a purple base and an off-white distal region. H. trionum belongs to the Trionum Complex native to Australia and New …

Polarity establishment and signalling mechanisms controlling patterning in Hibiscus Trionum petals
… Hibiscus trionum flowers produce a striking bullseye pattern by specifying cells with different pigmentation, shape, and texture in different regions of the adaxial petal epidermis. However, the mechanisms controlling cell differentiation across the petal surface to form such an elaborate and …

ADPATIVE MODE MATCHING UPGRADE FOR ADVANCED LIGO
… optical cavity generates a Laguerre-Gauss bullseyemode LG01. A cylindrical lens mode converting telescope can then optically convert the bullseye mode into a 45! rotated Hermite-Gauss pringle mode HG11. The rotated mode is perfectly shaped for detection by the existing quadrant photodiode …

Cultivar, Mowing Height, and Herbicide Effects on Bermudagrass, Cynodon Dactylon [L.] Pers., Suppression in Tall Fescue, Schedonorus Arundinaceus [Schreb.] Dumort., Nom. Cons.
… for one study and the turf type cultivar ‘Bullseye’ was utilized in the other. In the fall of 2011, glyphosate (Roundup Pro) was applied to selected plots at the rate of 0.36 kg ae/ha. ‘KY 31’ and ‘Bullseye’ tall fescues were sown into an existing mixed stand of common and hybrid …

Applications of Cathodoluminescence in Plasmonic Nanostructures and Ultrathin InAs Quantum Layers
… materials. Furthermore, a hybridized Au/Ag bullseye nanostructure has been designed and fabricated by the focused ion beam milling. Investigated by the CL process, we find that the hybridized plasmonic emission can be manipulated by the excitation position of the electron beam and the …

Diamond nanophotonic devices for quantum information processing and sensing
… qubits. Chapter 6 introduces a circular diamond "bullseye" grating that achieves the highest reported photon collection rate from a single NV center of 4.56 0.08 Mcps at saturation when fitted with the widely-used background counts subtraction method. We also quantified the emission by a …

Pseudomonas spp. Isolated from Soybean Nodules Promote Soybean Growth and Nitrogen Fixation
… spp. strains (referred to in this study as Bullseye, Pancake, and Starfish) and an uninoculated control. Soybeans were harvested at two time points: the R2/R3 growth stage and the R6 growth stage. Following each harvest, measures of growth, yield, and nitrogen fixation were taken, and data …

Effects of deficit irrigation frequency on plant growth, water use and physiology of Pelargonium x hortorum and tomato (Solanum lycopersicum L. cv. Ailsa Craig)
… substrate is limited. Pelargonium x hortorum Bullseye plants were grown in glasshouse conditions under well-watered (WW; daily replacement of 100% of evapotranspiration (ET)), frequent (FDI), or infrequent (IDI) deficit irrigation regimes (50% of ET supplied daily or cumulatively every 4 days, …

Development and Optimisation of an Optofluidic Evanescent Field Nano Tweezer System for Trapping Nanometre Crystals for Synchrotron X-Ray Diffraction Experiments
… shape via the addition of either “doughnut” or “bullseye” nano plasmonic antennas on the surface of the optofluidic chip waveguides. When combined with a 1-D PhC resonator array they formed a hybrid waveguide that increased the electric field intensity from 1.10 × 10<sup>7</sup> V/m to 1.70 × …

Identifying female mobile bully-victim characteristics in selected high schools in South Africa: towards an anti-bullying mobile application
… in the form of a mobile application, called “The BullsEye!” through a Design Science process. The aim of the artefact was to proffer a technical intervention and observe the usefulness of the artefact in dealing with general bullying as well as for addressing, mitigating and providing support for …

Factors Associated with Pollinator Foraging and Floral Morphology of Lawn Weeds
The decline in pollinator populations poses a significant challenge to global food security, necessitating best management practices that minimize pollinator exposure to harmful pesticides. Many common weeds in managed turfgrass systems attract honey bees (Apis mellifera L.) and other pollinators, …
