introduction: aphasia is a common manifestation of stroke and evaluation of relationships of aphasia and brain topography could lead to better understanding of cognitive neurophysiology. methods: 100 stroke patients with aphasia admitted in valie-asr hospital, khorasan since april 2003 were enrolled in this prospective cross-sectional study. diagnosis of stroke and aphasia was made by a neurolo...

Topographical cues, independent of biochemistry, generated by the extracellular matrix may have significant effects upon cellular behavior. Studies have documented that substratum topography has direct effects on the ability of cells to orient themselves, migrate, and produce organized cytoskeletal arrangements. Basement membranes are composed of extracellular matrix proteins and found througho...

During synthetic interferogram generation (whereby a DEM and platform positions are used to calculate expected fringes), an interpolation step is necessary during the transformation from map geometry into the slant-range geometry of the radar image. Particularly in hilly terrain, assumptions made during the interpolation step can have an impact on the accuracy of the simulation. We investigate ...

Relationships between biophysical parameters and radiometric data have been tested and evaluated by several professionals using empirical and/or physical approaches. Remote sensing data collected from airborne or orbital platforms are, of course, influenced by different factors, such as illumination/observation geometry (data collection geometry), atmospheric effects, etc., rather than by targe...

Observations of the Moon obtained by the Moon Mineralogy Mapper (M) instrument were acquired at various local viewing geometries. To compensate for this, a visible near-infrared photometric correction for ...

Ocean models in box geometry forced by constant surface fluxes of density have been found to spontaneously generate interdecadal oscillations of the thermohaline circulation. This paper analyzes the sensitivity of these oscillations to various physical effects, including the presence of mesoscale turbulence, various thermal surface boundary conditions, and the presence of wind forcing or bottom...
