leaf anatomy, vascular traits and nanomechanical cell-wall properties in European beech provenances
<p>The file contains leaf anatomical data (thickness of individual leaf parenchyma layers), vascular traits of leaf midrib (vessel area and density and derived parameters), and nanomechanical properties of xylem cell walls (modulus of elasticity, adhesion, energy dissipation and deformation), which were studied in 15 provenances of European beech, originating from sites distributed across the whole range of the species. The trial plot (locality Tale in central Slovakia) was established in 1998 with 2-years-old seedling within the international provenance experiment with beech coordinated by the Institute of Forest Genetics of Thuenen Institute Grosshansdorf. Leaf anatomy was studied using light microscopy, while fluorescent microscopy was used to acquire vascular traits and atomic-force microscopy for nanomechanical cell-wall traits. Sun leaves were collected from 4 trees per provenances, 1 leaf per tree was analyzed. AFM was done in a subset of 8 provenances. The aim of the study was assessing geographical trends of the studied traits and their association with climate at the sites of origin to reveal potential adaptive variation patterns.</p>

DART-TOFMS of heartwood and xylem anatomy of Afzelia bipindensis and Afzelia pachyloba
<p>Anatomical and spectral data of heartwood of <em>Afzelia bipindensis</em> and <em>A. pachyloba. </em>The spectra was measured by direct analysis in real-time (DART) time-of-flight mass spectrometry (TOFMS) of 50 trees of <em>Afzelia bipindensis</em> and 39 of <em>A. pachyloba</em>. Specimens from the xylarium collection of the U.S. Fish and Wildlife Service in Ashland, Oregon, USA. Mass spectra of the emitted wood compounds were acquired in positive ion mode over the mass range of m/z 60 to 1100. Poly(ethylene glycol) 600 (Ultra Scientific, Kingstown, Rhode Island, USA) was used as a mass calibration standard after every fifth sample. The DART source parameters settings were the same as described by Espinoza et al. IAWA J 36: 311–325 (2015) and Evans et al. IAWA J 38: 266-281 (2017).</p> <p>Xylem vessel tangential lumen diameter (µm) measured in transverse sections of wood of five trees of <em>Afzelia bipindensis</em> and five of <em>A. pachyloba</em>.

FIGURE 5 U in Automated segmentation of insect anatomy from micro-CT images using deep learning
FIGURE 5 U-Net implementation. The architecture of the used convolutional neural network (CNN) is an implementation of U-Net. It consists of two parts: two 3×3 convolutions followed by 2×2 max pooling and two 3×3 convolutions followed by 2×2 upconvolutions. Dropout was added to avoid overfitting. As a final step a 1×1 convolution is applied, resulting in an output map with two classes.
