Ecological associations with arboreality during the evolution of body shape in Neotropical colubrid and dipsadid snakes
<p>Morphological evolution is frequently associated with ecological diversification, and ecomorphological patterns often express functional relationships involved in the range of tasks a group of individuals performs in a given environment. In some snakes, morphological traits related to locomotion seem to converge in association with an arboreal lifestyle, although such ecomorphological associations so far have not been described for species-rich lineages such as Colubridae and Dipsadidae. In addition to microhabitat usage, body shape may differ according to activity period if the surface area-to-volume (S/V) ratio differs between diurnal and nocturnal species. In this study, we address evolution of body shape in Colubridae and Dipsadidae from these two perspectives. We measured 61 species of Colubridae and Dipsadidae and classified snakes according to the arboreality degree based on the level of gravity exposure: non-scansorial (terrestrial), eurytopical (broadly arboreal/terrestrial) and stenotopical (narrowly adapted arboreal); and also, according to the activity period as diurnal or nocturnal. We predicted that higher degrees of arboreality and nocturnality represent derived states that evolved in association with slender and narrower bodies with longer tails, and consequently increased S/V ratios. Our ancestral reconstructions suggest that specializations towards arboreality and nocturnality evolved more recently during the diversification processes of these colubrids and dipsadids snakes. Most morphological traits of stenotopical species were similar to those of eurytopical ones, and only differed in relation to non-scansorial snakes, and body tapering in the anterior body region differed between non-scansorial and eurytopical species. We did not identify any morphological associations with activity period, suggesting that body shape in colubrid and dipsadid snakes evolved mostly associated to different degrees of specialization to arboreal habitats.</p>
Deep-Drawn U-Shaped Sheet Metal CAD Files Derived from NHTSA Crash Vehicles
<p>This dataset contains 90 U-shaped CAD geometries that are derived from the NHTSA crash vehicle simulation models. The geometries undergo a series of modifications:</p> <ul> <li>Shape Filtering: Select meshes suitable for deep drawing with a U-shaped profile.</li> <li>Duplicate Removal: Exclude symmetrical duplicates from vehicle structures.</li> <li>Boundary Representation Entity Definition: Place vertices on characteristic mesh features. Connect vertices with edges. Create faces from closed edge loops.</li> <li>Model Transformation: Orient models with drawing direction along -z, length along x, and width along y.</li> </ul> <p>The final CAD geometries represent the post-deep drawing state. Geometries are provided in neutral STEP format, each accompanied by an image. Further specifications are given in the associated publication(s).</p> <p>We want to thank the National Highway Traffic Safety Administration for providing the crash models and the allowance to publish a dataset. We want to inform users of the dataset that a sophisticated engineering evaluation has to be conducted whether the provided models should be used in crash simulation.</p>

FIGURE 15. Non-stationary associations between ecological diversity (AvPD) and standard deviation in altitude (ALTstd). The maps show the spatial variation in local beta coefficients (b) for ALTstd as predictor of AvPD, obtained from the full model, i.e., including all environmental predictors, after application of geographically weighted regression separately on data for each mammal group. Regions of (+) and negative (-) associations are indicated. Maps are in Mollweide equal-area projection. Dash lines on each map indicate the location of the tropics in the Northern and Southern Hemispheres.

Spectral data obtained by placing a multimodal interference filter with and without exfoliated graphite coating in a ring-shaped laser cavity
<p>This dataset contains the files obtained from the optical spectrum analyzer, by inserting a multimodal interference filter (MMIF) coated with graphite oxide into the ring-shaped laser cavity.<br> The data, according to the file name, is divided into three parts.<br> In one dataset are the spectrum of the cavity, at different pump powers, before inserting the MMIF. The other data set has the spectrum at different pump powers, with the MMIF without graphite oxide coating in the laser cavity. The last data set contains the spectrum at different pump powers, with the MMIF coated with graphite oxide inside the laser cavity.</p>
