A huge variety of Arthropod species is infected with endosymbiotic Wolbachia bacteria that manipulate their host's reproduction to invade populations. In addition to vertical transmission from mother to offspring through the egg cytoplasm, it has been demonstrated through phylogenetic analyses and natural transfer experiments that horizontal transmission of Wolbachia (i.e. contagion) can occur ...

11 With technical advances in wildlife telemetry, the study of cryptic predators’ responses to prey 12 distribution has been revolutionised. Considering marine predators, high resolution tagging 13 devices were developed lately to collect long and precise diving datasets. In this study, we 14 investigated, at fine temporal and spatial scales, changes in the horizontal movements and 15 diving pa...

We have synthesized epitaxial Au, Pd, and AuPd nanowire arrays in vertical or horizontal alignment on a c-cut sapphire substrate. We show that the vertical and horizontal nanowire arrays grow from half-octahedral seeds by the correlations of the geometry and orientation of seed crystals with those of as-grown nanowires. The alignment of nanowires can be steered by changing the atom flux. At low...

We propose an obstacle detection method based on trinocular stereo vision which consist of vertical and horizontal stereo cameras. Vertical edges and horizontal edges are extracted from horizontal stereo images and vertical stereo images. Then the edges are used to generate U-V-disparity maps. A rectangular obstacle has a characteristic that it is represented as a vertical line in V-disparity m...

The development of the asymmetry between horizontal and vertical eye tracking was investigated longitudinally at 5, 7, and 9 months of age. The target moved either on a 2D circular trajectory or on a vertical or horizontal 1D sinusoidal trajectory. Saccades, smooth pursuit, and head movements were measured. Vertical tracking was found to be inferior to horizontal tracking at all age levels. The...

Reaction time is known to depend on spatial stimulus-response compatibility in both the horizontal and the vertical dimensions. However, if both dimensions are varied in the same task, horizontal but not vertical compatibility affects performance, even if subjects are instructed to attend to the vertical dimension only (Nicoletti & Umiltà, 1984). Experiment 1 compared the effect of horizontal a...

this study aimed to compare the efficacy of mta and cem cement in class ii furcation defects in human mandibular molars.forty furcation defects were treated in 16 patients with chronic periodontitis. the clinical parameters of probing depth (pd), vertical and horizontal clinical attachment levels (vcal and hcal), open vertical and horizontal furcation depths (ovfd and ohfd), and gingival margin...

Our aim was to compare sensitivity for horizontal and vertical disparity corrugations and to resolve whether these stimuli are processed by similar or radically different underlying mechanisms. We measure global disparity sensitivity as a function of carrier spatial frequency for equi-detectable carriers and found a similar optimal carrier relationship for vertical and horizontal stimuli. Sensi...

The fact that the seen world appears upright is so obvious that it may seem axiomatic. Nevertheless this verticalhorizontal stability of phenomenal things is as much a psychological problem as their coloration, size, or distance. Stratton once asked the question, "why do things look right side up instead of inverted?" But a different and more fundamental question is, "why do things look right s...
