Using a moored source and horizontal/vertical line array combination, horizontal coherence properties of high signal to noise ratio (> or =20 dB) 100-1600 Hz signals have been measured. Internal waves in the area of the measurement created moving episodic sound-speed anomaly structures, influencing coherence length. Measured horizontal coherence scales for 100 Hz ranged from 5 to 20 acoustic wa...

PURPOSE To describe a video-based head-tracking technique to compensate for torsional, horizontal, and vertical in-plane head movements during pupil/iris-tracking video-oculography with a tilting haploscope. METHODS Custom software was developed for image acquisition and off-line analysis for a novel haploscopic viewing device. Head movements were constrained to the frontal plane with the use...

We develop a two-stage model for versioning products with respect to both vertical and horizontal attributes. At first, a firm positions its top-quality “flagship” product in a market with an imperfectly known distribution of tastes and reservation prices. In the second stage, the firm learns these consumer characteristics and has the option of extending its product line by versioning the flags...

Described is a module for the placement of items either on the same horizontal line or on top of each other. Alignment and separation of the items can be varied in horizontal and vertical direction as required. Titles can be added and their location, style and color speci ied.

In Section 4.1 of the main paper, we describe the quadrilateral-based sampling algorithm. Here, we further show in Figure 1 an example of how a quadrillateral is sampled from vanishing lines. First, from all the detected horizontal vanishing directions, we randomly select one of them; and among all the vanishing lines belonging to the selected horizontal vanishing direction, we randomly select ...

After a cue directing attention to one side, anterior event-related potentials (ERPs) show contralateral negativity (anterior directing attention negativity, ADAN). It is unclear whether ADAN effects are contaminated by contralateral negativity arising from residual gaze shifts. Conversely, it is possible that ADAN-related potentials contaminate the horizontal electrooculogram (HEOG), via volum...

In the horizontal-vertical illusion (HVI), the length of the vertical line is overestimated, whereas in the bisection illusion (BI), the horizontal bisecting line is expected to be overestimated. Here, only half of our 22 observers showed the expected BI, whereas the other half underestimated the bisecting line. Observers also differed in their judgments of the strength of the HVI: The HVI was ...

We investigated the dependency of the early facilitatory effect of a prime stimulus (S1) on the physical characteristics of the target stimulus (S2). A go-no go reaction time paradigm was used. The S1 was a gray ring and the S2s were a white vertical line, a white horizontal line, a white cross and a white small ring, all inside a white ring with the same dimensions as the S1. S1 onset-S2 onset...

Mechanical axiography was performed on 49 (37 female, 12 male) patients prior to orthodontic treatment, after removal of the fixed appliance, and at the end of retention. Twenty-five subjects (mean age 12.8 years) underwent orthodontic treatment without premolar extractions (group 1) and 24 subjects (mean age 13.5 years) with premolar extractions (group 2). The axiographic tracings of the protr...

Impaction most commonly involves lower third molars, followed by permanent upper canines. Warford et al11 used a bi-condylar line as a horizontal reference line to predict the maxillary canine impaction in mixed dentition. The measurement was taken of the mesial angle formed by using the constructed horizontal and the long axis of the maxillary canine. In this study, a modified Warford method w...
