Two illusions of visual movement-induced movement, and the aftereffect of movement-an interact. induced apparent movement of stationary areas can produce an aftereffect. and conversely. an aftereffect of real movement can induce apparent movement into stationary neighboring areas. The real movement of images across the retina can produce two distinct illusions of movement. First, a small statio...

The vertical corneal meridia are not kept perpendicular to the horizon in human and nonhuman primates when the head or body is tilted, i.e., compensatory counter-rolling of the eyes does not occur. The slight torsional displacement of the vertical corneal meridia noted by many observers may be the result of rotation around an axis or to translation of the globe. The neurologic and structural sy...

A test program was conducted to determine the effectiveness of a seat belt restraint in preventing occupant movement in a rollover accident. A baseline type-2 seat belt (pelvic and torso restraint), and an improved type-2 seat belt restraint, both designed to restrict occupant motion in a rollover accident, were tested in a rollover restraints tester (RRT). Each seat belt was placed on a H-III ...

[1] We use ten years of GPS data from nine continuous and six semi‐continuous GPS stations in a transect across the Southern Alps to measure rates of relative vertical movement with typical 1s uncertainties of 0.3–0.5 mm/yr. The estimated vertical rates define a fairly smooth profile across the range, with the highest rates of ∼5 mm/yr found near the crest of the mountains and ∼20–30 km southea...

A desire to look attractive is no longer taken as a sign of vanity. Since the face is the most exposed part of the body, and the mouth a prominent feature, teeth are getting a greater share of attention. The severe wear of anterior teeth facilitates the loss of anterior guidance, which protects the posterior teeth from wear during excursive movement. The collapse of posterior teeth also results...

To evaluate the long-term surgical outcomes of anterior transposition of the inferior oblique muscle (ATIO) in the treatment of vertical deviations resulting from superior oblique palsy (SOP). We retrospectively studied seven consecutive patients who had undergone ATIO for the treatment of SOP. A follow-up of at least five years after the operation was required to be included in the study. In r...

Vertical transmission of dengue viruses by mosquitoes was discovered at the end of the late 1970s and has been suggested to be a means by which these viruses persist. However, it is unclear how widespread it is in nature, and its importance in the epidemiology of this disease is still debated. Here, we review the literature on vertical transmission and discuss its role in dengue's epidemiology ...

Predatory fishes, such as tunas, billfishes, and sharks, coexist in pelagic regions of the tropical oceans. In situ experiments have revealed horizontal and vertical movement patterns for different pelagic species, but the influence of the biotic environment on movement behaviour has not been studied. In this paper, we propose a simple model in which the movement behaviour of these fishes is dr...

The evolutionary implications of the path-analysis model most often used in human behavior genetics are examined. With directional selection, a model of pure vertical environmental transmission does not respond in a fully adaptive fashion. Unless the coefficients of transmission are exactly O. 50, the population mean will not equilibrate at the selective optimum over time. I f there is both gen...
