This paper examines downward price rigidity in Iranian house market and discusses whether this characteristic would result in an asymmetric relationship between house price and monetary policy. To test the downward house price rigidity the threshold GARCH model is employed. The asymmetric adjustment to monetary policy is examined using the asymmetric cointegration and error correction models. T...
A target that is nearer to one eye than the other subtends a larger visual angle in the closer eye. Consequently, when making saccades between vertically separated targets that are closer to one eye, there is a vertical retinal disparity that must be overcome by a change in the relative alignment of the eyes. We recorded eye movements in three normal subjects and showed that in such viewing cir...
magnetic survey is nowadays the most efficient non-destructive geophysical method. this technique puts emphasis on the measurement of anomalies of the earth’s magnetic field, caused by the presence of archaeological remains in the ground. magnetic survey is one of the oldest geophysical methods for airborne and land use. that is why there is a large volume of data that could be used for geologi...
facial deficiency or true mandibular prognathism are difficult to manage nonsurgically, particularly when a hyperdivergent mandibular growth pattern creates an anterior open bite. For the past 25 years, early growth modification of midfacial deficiency with expansion and facemask therapy has been the standard treatment for Class III malocclusions.1,2 A disadvantage of this ap proach is that it ...
for a given riemannian manifold (m,g),it is an interesting question to study the existence of a conformal diffemorphism (also called as a conformal transformation) f : m ! m such that the metric g? = fg has one of the following properties: (i)(m; g?) has constant scalar curvature. (ii)(m; g?) is an einstein manifold.
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
vocabulary as a major component of language learning has been the object of numerous studies each of which has its own contribution to the field. finding the best way of learning the words deeply and extensively is the common objective of most of those studies. however, one effective way for achieving this goal is somehow neglected in the field. using a variety of activities such as games can r...
Humans demonstrate preferences to use egocentric or allocentric reference frames in navigation tasks that lack embodied (vestibular and/or proprioceptive) cues. Here, we investigated how reference frame proclivities affect spatial navigation in horizontal versus vertical planes. Point-to-origin performance after visually displayed vertical trajectories was surprisingly accurate and almost match...
