residential mobility is an important ecological mobility which, besides physical impacts, has contributed in shaping or reshaping of urban social milieus. the analyses of results related to a sample of 17510 households inhabiting in 40 regions of mashhad indicates that 46.9 percent of them had experienced a residential relocation during a period of ten years, the maximum of which (62.8 percent)...

and reactive normally to light, associated with subtle left eyelid ptosis. Five days later, his diplopia had resolved. On voluntary vertical gaze, trace upward and downward movement returned. Oculocephalic maneuver elicited downward saccade but failed to hold the downward gaze, and elicited no upward gaze ( fig. 1 A). Vertical saccades and pursuit returned normal on follow-up examination 2 week...

Downward continuation (DC) of the gravity potential field is an important approach used to understand and interpret density structure boundary anomalous bodies. It widely delineate highlight local shallow sources. However, it well known that direct DC transformation in frequency domain unstable easily affected by high-frequency noise. Recent deep learning applications have led development image...

The gain of saccadic eye movements can be altered gradually by moving targets either forward or backward during targeting saccades. If the gain of saccades to targets of only one size is adapted, the gain change generalizes or transfers only to saccades with similar vectors. In this study, we examined the spatial extent of such saccadic size adaptation, i.e., the gain adaptation field. We also ...

to solve the geodetic boundary-value problem the gravity anomalies have to be continued from the earth's surface down onto the geoid surface. helmert’s gravity anomalies (multiplied by the geocentric radius) are harmonic above the geoid. it is thus possible to use them in the poisson solution of the inverse dirichlet boundary value problem to get their values on the geoid. the downward con...
