BRAIN Journal-Participative Teaching with Mobile Devices and Social Networks for K-12 Children-Figure 10. The educational blog on Google+ Time Maps page – the glass manufacturing techniques
<p>For this subject two video films were posted on Google+ (a performance and a 3D<br> reconstruction), slightly different from those available on the Time Maps web site, but containing<br> the same information. The children had to make a little effort to relate this information with the one<br> presented on the site, to make a connection between the questions, the fragments from videos at<br> which the answers referred to and the information from the site.<br> The set of questionnaires lead the school children through the majority of data offered by the<br> web site regarding to the two historical periods (Figures 9, 10).</p>
Is the Gaze Behavior During Stair Walking Affected by Pregnancy?-Figure 2. Eye-tracking glasses image showing the gaze location during stair ascent
<p>At each data collection, participants walked the same U-shaped staircase descending a 22- treads (riser: 0.16 m, run: 0.33 m, and width: 1.15 m), making a short U-turn downstairs and ascending back the staircase, one tread at a time (Figure 1). Only the data of stair walking were taken for further analysis. The staircase was equipped with a handrail on one side but none of the participants used it. To monitor the gaze a SensoMotoric Instruments (SMI) eye-tracking glasses (ETG) system (SMI, Inc.) at a frequency of 60 frames per second and 1280x960 pixel picture was used. Calibration was performed using a matrix of 3 points placed on a board in different highs and different horizontal placement. Mean gaze vectors of the right eye (x, y, z) for stair descent and stair ascent were obtained for each data collection session. Gaze vector x, y, z starts at the eye and heads off in mediolateral, up and down, and anterior-posterior direction, respectively (Figure 2) (Haffegee, Alexandrov, & Barrow, 2007; Scheel, & Staadt, 2015).</p>

Data-Driven Modelling of Daylight Scattering by Roman Window Glass. ACM Journal on Computing and Cultural Heritage (manuscript accepted with minor revisions). For each sample, a sub-directory contains the measured DSF (BSDF x cos theta) and a transmission and reflection model for use with the light simulation software Radiance.</p> <p>Each directory contains metadata in Dublin Core and Marc21 format, giving detailed information about the individual dataset.</p>
Text-fig. 2. Eospondylus primigenius (STÜRTZ) Bundenbach, Eschenbach-Bocksberg quarry, Lower Devonian, Lower Emsian (Zlichovian), Hunsrück Slate,, NM S 4764, x 3. Specimen with ventral arm coiling. The specimen is on its dorsum in slate with all five rays curled ventrally inward toward mouth area on underside of disk. Barely visible are tips of two jaws; slightly exposed are proximal parts of rays in oral view extending outward from disk. The location of abrupt ventral bending of rays is indicated by emergence from slate of five rays in aboral view that point inward toward buried disk. Based on ventral bending of rays and intimate association with crinoids Eospondylus has been interpreted as stratigraphic first occurrence of Order Euryalida, which contains epizoic gorgonocephalid and euryalid basket-stars of modern oceans. This status is rejected using new evidence from isolated vertebrae.

Figure 1. Phylogenetic relationships among genera and species groups within Centrolenidae. A in Glass frogs (Centrolenidae) of Yanayacu Biological Station, Ecuador, with the description of a new species and comments on centrolenid systematics
Figure 1. Phylogenetic relationships among genera and species groups within Centrolenidae. A, tree topology suggested by Ruiz-Carranza & Lynch (1991a, b, c, 1996, 1998) and modified by Bolívar et al. (1999), Señaris (2001) and Duellman & Señaris (2003). B, single, most-parsimonious tree of the phylogenetic relationships of Centrolenidae (tree length = 13, CI = 0.923, RI = 0.9474, RC = 0.8745). Numbers refer to the following characters: (1) tibiale and fibulare, 0 = not fused, 1 = partially or completely fused; *(2) T-shaped terminal phalanges, 0 = absent, 1 = present; (3) dilated medial process on Metacarpal III, 0 = absent, 1 = present; (4) eggs deposition site, 0 = deposited in water, 1 = not deposited in water, 2 = deposited on underside of leaves; (5) shape of liver, 0 = liver lobed, 1 = liver bulbous; (6) humeral spine in males, 0 = absent, 1 = present; (7) relative size of disc of Finger III, 0 = disc small (<80% of eye diameter), 1 = disc large (> 80% of eye diameter); (8) coloration of hepatic peritoneum, 0 = clear, 1 = white; (9) coloration of peritoneum covering urinary blad- der, 0 = clear, 1 = white; (10) red heart visible in ventral view, 0 = heart not visible, 1 = red heart visible; (11) coloration of parietal peritoneum, 0 = white, 1 = clear. Character 12 (venter-to-venter fight behaviour) was hypothesized to be a synapomorphy shared by Centrolene and Cochranella (Bolívar et al., 1999); however, the distribution of this behaviour has been reported in only nine species (Guayasamin & Barrio-Amorós, 2005) and we did not include in B. Numbers next to tick marks represent bootstrap support values. Grey boxes denote characters that appear more than once in the tree. *T-shaped terminal phalanges are also present in Allophryne ruthveni.

Figure 2 in Glass frogs (Centrolenidae) of Yanayacu Biological Station, Ecuador, with the description of a new species and comments on centrolenid systematics
Figure 2. Terminology (modified from Savage & Heyer, 1967) used for webbing formula in hands and feet. Roman numerals represent fingers or toes; Arabic numerals represent the number of phalanges completely or partially free of webbing. We use 0– to indicate that the web reaches the distal margin of the disc; 0 indicates that the web reaches the middle of the disc; 0+ indicates that the web reaches the proximal margin of the disc; 1– indicates that the web reaches the distal margin of the intercalary cartilage; 1 indicates that the web reaches the middle of the intercalary cartilage; 1+ indicates that the web reaches the proximal margin of the intercalary cartilage; 2– indicates that the web reaches the distal margin of the distal subarticular tubercle; 2 indicates that the web reaches the middle of the distal subarticular tubercle; 2+ indicates that the web reaches the proximal margin of the distal subarticular tubercle; the notation for 3 and 4 follow the same pattern described for 2. When, for example, the webbing reaches a midpoint between the intercalary cartilage and the distal subarticular tubercle in Finger IV, and the proximal margin of the disc in Finger V, the appropriate notation between these two fingers would be IV 11/2−0+ V. Scale bar = 2 mm.
