Dynamics of snakes and ladders.
D. J. Field, A. Hayes, and R. F. Hess (1993) introduced two types of stimulus to study the perceptual integration of contours. Both types of stimulus consist of a smooth path of spatially separate elements, embedded in a field of randomly oriented elements. In one type of stimulus ("snakes"), the elements form tangents to the path of the contour; in the other type ("ladders"), the elements are ...
متن کاملMedical humanities in Nepal--snakes and ladders.
In the last decade there has been a quantitative growth in medical schools in Nepal, a developing country in South Asia. Medical Humanities (MH) uses disciplines traditionally termed as the humanities in the pursuit of medical educational goals. The subject is slowly developing in Nepal. Sessions have been conducted at Manipal College of Medical Sciences, Pokhara and KIST Medical College, Lalit...
متن کاملSnakes, ladders, and isolas of localised patterns
Stable localised roll structures have been observed in many physical problems and model equations, notably in the 1D Swift–Hohenberg equation. Reflection-symmetric localised rolls are often found to lie on two “snaking” solution branches, so that the spatial width of the localised rolls increases when moving along each branch. Recent numerical results by Burke and Knobloch indicate that the two...

متن کاملOptical snakes and ladders: dispersion and nonlinearity in microcoil resonators.
Microcoil resonators are a radical new geometry for high Q resonators with unique linear features. In this paper I briefly summarise their linear properties before extending the analysis to nonlinear interactions in microcoil resonators. As expected such nonlinear resonators are bistable and exhibit hysteresis. Finally I discuss possible applications and extensions to such resonators.
