The properties of the iterative phase-retrieval ptychographical imaging technique are modelled. We use the multi-slice method to generate a series of diffraction patterns when a small convergent illumination spot is moved across a silicon crystal orientated in the 100 direction. These are then used to reconstruct the transmission function of the sample by solving the phase of diffraction patter...

Synesthesia refers to additional sensations experienced by some people for specific stimulations, such as the systematic arbitrary association of colors to letters for the most studied type. Here, we review all the studies (based mostly on functional and structural magnetic resonance imaging) that have searched for the neural correlates of this subjective experience, as well as structural diffe...

2,3,7,8-tetrachlorodibenzo-p-dioxin (tcdd) is a by-product o f t he trichlorophenol (herbicide) production and is also produced through a variety of combustion processes. it appears that tcdd is a ubiquitous chemical, particularly in industrialised countries, and the liver is the target organ of its toxicity. the prominent hepatotoxic effect of tcdd is progressive centrilobular necrosis. the is...

the relationship between topography, soil factors, and distribution of ecological vegetation groups in the nodoushan arid rangelands of yazd province (iran) was investigated. the present species were recorded in each vegetation group using a randomized-systematic sampling method. plant cover and density were estimated quantitatively using the transect and quadrate methods, and the two-way indic...

bactrian was the language of bactria in northern afganistan. this language is considered as one of the eastern middle iranian languages which was used from the first to the ninth century. the remaining materials from this language include coins, seals, inscriptions and documents. in 1990s, many bactrian documents were found amongst which the letters were of most importance as they gave much mor...
