Construction, validation and application of nocturnal pollen transport networks in an agro-ecosystem: datasets collected using light microscopy and DNA metabarcoding
<p>This dataset contains all data required to reproduce the analyses conducted in Macgregor <em>et al. </em>(2018), using the R Notebook archived at doi: <a href="https://dx.doi.org/10.5281/zenodo.1322712">10.5281/zenodo.1322712</a>.</p> <p>Specifically, the dataset contains details of pollen transport detected on two matched samples, each containing 311 moths of 41 species, using two methods: a traditional light microscopy approach and a novel DNA metabarcoding approach. Both raw and manually-curated versions of each dataset are archived for full clarity. The dataset additionally contains all metadata required to fully interpret these data, including the RGB tables used to prepare Fig 4 in Macgregor <em>et al. </em>(2018).</p> <p>Macgregor <em>et al. </em>(2018) Construction, validation and application of nocturnal pollen transport networks in an agro-ecosystem: a comparison using light microscopy and DNA metabarcoding. <em>Ecological Entomology</em>, doi: <a href="https://dx.doi.org/10.1111/een.12674">10.1111/een.12674</a>.</p>

Diurnal regulation of photosynthetic light absorption, electron transport and carbon fixation in two contrasting oceanic environments
<p>Dataset accompanying the publication Schuback N & Tortell PD, Diurnal regulation of photosynthetic light absorption, electron transport and carbon fixation in two contrasting oceanic environments, Biogeosciences, 2019. https://doi.org/10.5194/bg-2018-524.</p>
Gone in 60 Nanoseconds: Transient Light Transport in Cornell Box
<p>Transient light transport in the Cornell Box using transient photon map in RADIANCE. The existing kd-tree data structure to store the photons was extended to 4D, with the photons' time-of-flight as fourth dimension. This simple example demonstrates one aspect of transient rendering that is lost in steady state lighting: it reveals fleeting phenomena that (mostly) disappear when lighting reaches equilibrium. Note the strong colour bleeding on the central white wall from the 1st bounce off the flanking red and blue walls (see t=3.0 nsec). This effect is neutralised by secondary interreflections, and barely noticeable in steady state. This example also demonstrates the current prototype's limitations; transient rendering is limited to diffuse surfaces (note the steady-state specular reflections on the dielectric sphere), and the speed of light is assumed to be constant, i.e. independent of the index of refraction.</p>
Gone in 60 Nanoseconds: Transient Light Transport in Villa Müller
<p>Simulation of transient light transport in a model of the Villa Müller in Prague. This used 200M transient photons and spans 100nsec. The building is shown as two cross-sectional views as seen facing northwest and southeast. This visualisation reveals many transient phenomena, including prominent colour bleeding and specular reflections from the red marble floor in the dining hall and dining room, some of which ripples back upstairs from this area. In addition, there is diffuse interreflection between adjacent walls in the upper stairwell, which cast shadows revealing the handrails.</p>
