We investigated whether vertical-shear disparity was extracted from the whole visual field or from a more local area and how global estimates of vertical disparity are derived. We also investigated the role of cyclovergence in processing shear disparity. Random-dot stereoscopic displays in various configurations were presented with horizontal-shear disparity, vertical-shear disparity or same-si...

We study the Gauss map of minimal surfaces in the Heisenberg group Nil3 endowed with a left-invariant Riemannian metric. We prove that the Gauss map of a nowhere vertical minimal surface is harmonic into the hyperbolic plane H. Conversely, any nowhere antiholomorphic harmonic map into H is the Gauss map of a nowhere vertical minimal surface. Finally, we study the image of the Gauss map of compl...

Introduction In Fig. 1 we sketch tentative features of the QCD phase diagram in the κ, μ, T space. Since a general description is missing, one may try to concentrate on special situations, such as the “quenched” limit [1] (see below), represented by the thick vertical dashed line at infinite μ in the κ = 0 plane. For a more physical situation we consider a vertical plane at small but non-zero κ...

The coordinate and energy distributions of the electron beam density at the Advanced Light Source have been obtained from measurements of the beam lifetime at various storage-ring apertures in the horizontal and vertical planes. It is shown that these distributions have a Gaussian core extended approximately up to five rms beam sizes. Beyond this point the electron density is defined by the ele...

We construct complete embedded minimal surfaces in H × R. The first one is a finite total curvature surface which is conformal to S \ {p1, ..., pk}, k ≥ 2; the second one is a 1-parameter family of singly-periodic minimal surfaces which is asymptotic to a horizontal plane and a vertical plane; the third one is a 2-parameter family of minimal surfaces which have a fundamental piece of finite tot...

This paper focus on the analysis of the navigation task in a 3D virtual tunnel. We localized the neural structures responsible for egocentric and allocentric reference frame processing in horizontal and vertical plane and also analyzed specific segments of the tunnel traverse. We identified intrahemispheric coherences in occipital-parietal and temporalparietal areas as the most discriminative f...

Our aim was to examine the thigh, as a potential locus for directional orienting, within the vertical plane when the operator is seated (Figure 1). Specifically: (a) Examine the ability to locate a vibrotactile stimulation embracing the thigh. (b) Determine which region along the thigh provided more accurate localization. (c) Compare different burst durations and pulse repetitions which could l...

In the recent paper [12] we have proved that the only stable C minimal surfaces in the first Heisenberg group Hn which are graphs over some plane and have empty characteristic locus must be vertical planes. This result represents a sub-Riemannian version of the celebrated theorem of Bernstein. In this paper we extend the result in [12] to C complete embedded minimal surfaces in H with empty cha...

introdouction: impacted and partially erupted third molars can cause various symptoms and pathologies. the aim of this study was to determine the association between commonly observed pathological conditions and the impaction depth of lower third molar teeth. materials and methods: in this retrospective study, 370 panoramic radiographs including 724 lower third molars were evaluated to assess s...
