Fig. 6 in Morphological characters and SNP markers suggest hybridization and introgression in sympatric populations of the pleurocarpous mosses Homalothecium lutescens and H. sericeum
Fig. 6 The positions of putatively hybrid sporophytes from the sympatric populations of H. lutescens and H. sericeum superimposed in the PCA from Fig. 5, based on leaf morphology of the maternal gametophytes. The morphospace of leaves from allopatric populations of H. lutescens and H. sericeum are shown as encircled surfaces (blue circle = H. lutescens and yellow circle = H. sericeum). The red circle represents the morphospace of individuals from the sympatric populations. Each square represents a hybrid sporophyte specimen, collected on its
Fig. 5 in Morphological characters and SNP markers suggest hybridization and introgression in sympatric populations of the pleurocarpous mosses Homalothecium lutescens and H. sericeum
Fig. 5 Principal component analysis of 14 leaf characters from 240 specimens representing allopatric and sympatric populations of Homalothecium lutescens and H. sericeum. The first two axes (PC1 and PC2) representing together 36% of variation are shown. The colours and shapes of data points correspond to the population of the specimens. Leaf
Fig. 2 in Morphological characters and SNP markers suggest hybridization and introgression in sympatric populations of the pleurocarpous mosses Homalothecium lutescens and H. sericeum
Fig. 2 (a) Measurement of capsule orientation in relation to the seta in Homalothecium as the angle (in degrees) between the seta and spore capsule at the basis of the spore capsule. (b) Capsule inclinations of individuals from the allopatric populations fell into the black ranges of variation; in the sympatric populations individuals occurred with capsule inclinations ranging outside typical capsule inclinations of the pure species (red zone: 150°- 164°), indicating hybrid origin
A Corpus-driven Study of Contrastive Markers in Cantonese‒English Political Interpreting-Figure 4. The frequency of different source segments of "but" in the Cantonese sub-corpus
<p>Likewise, Figure 4 lists all the Cantonese source segments of but and their frequency. The results show that most of the use of but was contributed by daan (hai) — its closest equivalence in Cantonese. However, there were 52 instances of the use of but which corresponded to no source segments at all in the Cantonese sub-corpus, indicating, again, the possibility of explicitation. The rest of the 16 instances of but were attributed by the use of the Cantonese markers ji (而 (frequency=8; close in meaning to however and but, indicating concession or contrast), followed by bat gwo (frequency=7) and koek (卻 (frequency=1; close in meaning to however and but, indicating concession or contrast).</p>
A Corpus-driven Study of Contrastive Markers in Cantonese‒English Political Interpreting-Figure 3. The frequency of different source segments of "however" in the Cantonese sub-corpus
<p>The use of however and but in the English sub-corpus was also investigated through looking into their source segments in the Cantonese sub-corpus. Figure 3 lists all the Cantonese source segments of however and their frequency. The figures show that the use of however mostly resulted from the employment of daan (hai) in the Cantonese source text (frequency=52). There were 24 instances of however which corresponded to no source segment at all, indicating a possible trend of explicitation — a feature of interpreted or translated language. Only 21 cases of however were caused by the use of bat gwo — its closest equivalence in Cantonese. The rest 4 cases resulted from the use of the Cantonese marker ho si (可是) (frequency=3; close in meaning to both however and but in English, indicating concession or contrast) and zeon gun (儘管 (frequency=1; close in meaning to although or in spite of in English, indicating concession or topic change).</p>
A Corpus-driven Study of Contrastive Markers in Cantonese‒English Political Interpreting-Figure 2. The frequency of different renditions of "daan (hai)" in the English sub-corpus
<p>The renditions of daan (hai) show a similar pattern (Figure 2). Among the 287 cases of daan (hai), the majority were interpreted into but (frequency=74) — its closest equivalence in English that signals denial and contrast. A total of 60 daan (hai) received no interpretation at all, which, again, indicates a possible mitigation strategy employed by the interpreter(s). Similar to the case of bat gwo, however — the other frequently used English marker apart from but — was the next most often employed rendition of daan (hai) in the English sub-corpus. In addition to but and however, daan (hai) was also rendered into the following English markers: although, despite, while, nevertheless, yet, having said that / that said, nonetheless, though, notwithstanding, on the other, regardless, even so, and after, most of which signal concession and topic change, with an even higher degree of subtlety as compared to however.</p>
A Corpus-driven Study of Contrastive Markers in Cantonese‒English Political Interpreting-Figure 1. The frequency of different renditions of "bat gwo" in the English sub-corpus
<p>The renditions of bat gwo and daan (hai) were closely examined by looking into how they were interpreted. Figure 1 lists all the renditions of bat gwo and their frequency. The figures show that bat gwo was most often interpreted into however (frequency=22) — its closest equivalence in English. There were, however, 7 cases that bat gwo was interpreted into but — its stronger and less subtle correspondence that indicates denial and contrast. Apart from rendering into these two most common English contrastive markers, there were also 5 cases that bat gwo was not interpreted at all, suggesting a possible mitigation strategy employed by the interpreter(s). Likewise, the rest of bat gwo were rendered into other markers including nevertheless, nonetheless, while, yet, having said that / that said, all of which indicate concession and topic change, yet with an even higher degree of subtlety as compared to however.</p>

Mocap gait motion samples - Optical marker trajectories
<p>=======================<br> <strong>Summary</strong><br> =======================<br> This database gathers a set of optical marker-based motion capture (mocap) tracking samples. Each sample corresponds to a single acquisition containing the 3D trajectories of a set of markers along a continuous interval of time.</p> <p>Keywords: Motion capture, mocap, Gait analysis, marker tracking.</p> <p>=======================<br> <strong>Data description</strong><br> =======================<br> Several persons wearing small reflective balls (markers) were asked to walk normally while recorded using motion capture cameras. These cameras, previously calibrated, are thought to detect the 2D pixel image position of the markers against the background thanks to IR lightning they are provided with. The XYZ position can be afterwards recovered by means of photogrammetric methods, whereas the tracking is kept across the frames. This data set contains the raw 3D trajectories of the aforementioned markers along the time.</p> <p>The set of markers is the layout proposed by Kadaba, Ramakrishnan, and Wootten, from the Helen Hayes Hospital. More details can be found in 'Dynamics of Human Gait' from Vaughan et al. Check out 'HH_marker_arrangement.png' for a visual description on marker placement.</p> <p>This database was built on purpose to serve as ground truth for the doctoral research "Cloud Point Labeling in Optical Motion Capture Systems", written by Juan L. Jiménez B. and supervised by Prof. Manuel Graña, from the Computational Intelligence Group, University of the Basque Country (UPV/EHU), and expected to be presented by the beginning of 2019.</p> <p>This work has been partially supported by the EC through project CybSPEED funded by the H2020 MSCA-RISE grant agreement Num. 777720.</p> <p>=======================<br> <strong>Equipment</strong><br> =======================<br> The following elements were taken to harvest the data:<br> - Six (6) motion capture cameras model S250e from Natural Point Inc. ( https://optitrack.com/ );<br> - Fifteen (15) passive-reflective optical markers;<br> - One computer running motion capture software from s.t.t.;<br> - A number of other minor accessories as camera wall mounts, Ethernet wires, adhesive tape, coffee and time.</p> <p>=======================<br> <strong>Technical details</strong><br> =======================<br> Database size: 71 recordings between 1.5 and 7 seconds long, summing up more than 20.000 frames<br> Exercise: regular gait motion at different paces<br> People: 14 different persons of different ages and shapes were recorded. No gait pathologies openly acknowledged.<br> Number of markers: 15 (Helen Hayes marker system)<br> Native camera resolution: 800x800 pixels<br> Sampling frequency: 100Hz<br> Cartesian units: millimeters<br> Right handed reference frame, +Y vertical upwards, ground height at Y=~0</p> <p>=======================<br> <strong>Data base format</strong><br> =======================<br> The database is composed by 71 different files, one per gait sequence. Each file is written in plain ASCII, comma separated values (CSV) format. Each line represents an instant of time (frame) containing the 3D Cartesian positions of all the 15 markers with to 2 mantissa digits and dot symbol as decimal separator. A triple 'nan nan nan' instead of actual numbers stands for marker occlusion and consequently no measured position can be given. The coordinates are numerically arranged as follows:<br> <br> X1; Y1; Z1; X2; Y2; Z2; ... Xi; Yi; Zi; ... X15; Y15; Z15;<br> <br> ... where 'i' refers to the i-th marker among the following list:</p> <p> 1- Right ASIS<br> 2- Left ASIS<br> 3- Sacrum<br> 4- Right Femoral wand<br> 5- Left Femoral wand<br> 6- Right Femoral epicondyle<br> 7- Left Femoral epicondyle<br> 8- Right Tibial wand<br> 9- Left Tibial wand<br> 10- Right Malleolus<br> 11- Left Malleolus<br> 12- Right Heel<br> 13- Left Heel<br> 14- Right Metatarsal head II<br> 15- Left Metatarsal head II</p> <p>=======================<br> <strong>Privacy statement</strong><br> =======================<br> The personal privacy of the volunteers, adults of 25 and over, remains protected since no confidential data has been collected at any time.</p> <p>The authors count on the express written consent of the company to use the gathered data in the scope of academic research and as ground truth for the aforementioned PhD Thesis, including its publication under the specified license terms.</p> <p><br> =======================<br> <strong>Further information</strong><br> =======================<br> If you find any mistake or experience any trouble in the interpretation of the data, please do not hesitate to contact us.</p> <p> </p>
