Abstract Advances in genomics have expedited the improvement of several agriculturally important crops but similar efforts wheat ( Triticum spp.) been more challenging. This is largely owing to size and complexity genome 1 , lack genome-assembly data for multiple lines 2,3 . Here we generated ten chromosome pseudomolecule five scaffold assemblies hexaploid explore genomic diversity among from global breeding programs. Comparative analysis revealed extensive structural rearrangements,...
Open-source software development projects are almost always collaborative and distributed. Despite the difficulties imposed by distance, these have managed to produce large, complex, successful systems. However, there is still little known about how open-source teams manage their collaboration. In this paper we look at one aspect of issue: distributed developers maintain group awareness. We interviewed developers, read project communication, looked artifacts from three open source projects....
Guidelines for designing information charts (such as bar charts) often state that the presentation should reduce or remove 'chart junk' - visual embellishments are not essential to understanding data. In contrast, some popular chart designers wrap presented data in detailed and elaborate imagery, raising questions of whether this imagery is really detrimental has been proposed, embellishment may have other benefits. To investigate these issues, we conducted an experiment compared embellished...
Interactive systems often require calibration to ensure that input and output are optimally configured. Without calibration, user performance can degrade (e.g., if an device is not adjusted for the user's abilities), errors increase color spaces matched), some interactions may be possible use of eye tracker). The value lost, however, because many processes tedious unenjoyable, users avoid them altogether. To address this problem, we propose games gather data in engaging entertaining manner....

We designed, implemented, and evaluated a new concept for visualizing searching databases utilizing direct manipulation called dynamic queries. Dynamic queries allow users to formulate by adjusting graphical widgets, such as sliders, see the results immediately. By providing visualization of database search results, can find trends exceptions easily. User testing was done with eighteen undergraduate students who performed significantly faster using interface compared both natural language...
Researchers in Computer Supported Cooperative Work have recently developed discount evaluation methods for shared-workspace groupware. Most rely on some understanding of the context which groupware systems will be used, means that evaluators need to model tasks groups perform. However, existing task analysis schemes are not well suited needs evaluation: they either do deal with collaboration issues, use an appropriate level concrete assessment usability interfaces, or adequately represent...

Menus are a primary control in current interfaces, but there has been relatively little theoretical work to model their performance. We propose of menu performance that goes beyond previous by incorporating components for Fitts' Law pointing time, visual search time when novice, Hick-Hyman decision expert, and the transition from novice expert behaviour. The is able predict many different designs, including adaptive split menus, items with frequencies sizes, multi-level menus. tested...
We introduce a conceptual framework that articulates the mechanics of collaboration for shared-workspace groupware: low level actions and interactions must be carried out to complete task in shared manner. These include communication, coordination, planning, monitoring, assistance, protection. The also includes three general measures these mechanics: effectiveness, efficiency, satisfaction. underlying idea is some usability problems groupware systems are not inherently tied social context...
Tag clouds are a popular method for visualizing and linking socially-organized information on websites. represent variables of interest (such as popularity) in the visual appearance keywords themselves - using text properties such font size, weight, or colour. Although tag becoming common, there is still little about which features tags draw attention viewers. As attempt to wider range with properties, it becomes difficult predict what will appear visually important viewer. To investigate...

To overcome display limitations of small-screen devices, researchers have proposed techniques that point users to objects located off-screen. Arrow-based such as City Lights convey only direction. Halo conveys direction and distance, but is susceptible clutter resulting from overlapping halos. We present Wedge, a visualization technique yet avoids overlap clutter. Wedge represents each off-screen location using an acute isosceles triangle: the tip coincides with locations, two corners are...
