TO THE EDITOR: A number of texts and articles indicate that dilatation of the hepatobiliary ducts may be suggested from findings on the HIDA study. This should be tempered by the well-known fact that an increase in radioactivity per unit volume in an object makes the image of an object appear larger (1). When there is stasis in the hepatobiliary tree, not necessarily accompanied by dilatation t...

this experiment was carried out at agricultural research station of gorgan during summer 2006 to study the effects of corn and green gram intercropping on forage yield, and weed biomass. the experimental design was rcbd with twelve treatments and four replications. a local green gram and corn single cross 550 were the crops employed. the experimental treatments consisted of sole corn and sole g...

this study investigated the status of mechanized power and self-propelled rice cultivation machinery in guilan province in northern iran. the raw data was obtained from 2013 statistics of the agricultural jihad organization of guilan province. power per unit of area, mechanization level, area per unit of self-propelled machinery, and mechanization requirement were calculated for eastern, wester...

Metamaterials are artificial structures composed of subwavelength unit cells to control electromagnetic (EM) waves. The spatial coding representation of metamaterial has the ability to describe the material in a digital way. The spatial coding metamaterials are typically constructed by unit cells that have similar shapes with fixed functionality. Here, the concept of frequency coding metamateri...

With the development of Internet and video capture techniques, videoconferencing becomes still more popular. However, with the increased size of the video resolution, the volume of the raw videoconferencing video data increases dramatically. The H.265/HEVC video compression standard can efficiently compresses the videoconferencing video, while the high compression rate is at the cost of heavy e...

The unit-derived method in coding theory is shown to be a unique optimal scheme for constructing and analysing codes. In many cases efficient and practical decoding methods are produced. Codes with efficient decoding algorithms at maximal distances possible are derived from unit schemes. In particular unit-derived codes from Vandermonde or Fourier matrices are particularly commendable giving ri...
