studying persian heroic epic verses affected by narrative tradition and shahname is one of the areas that can be analyzed from  different perspectives. samname which is considered as the last national epic in persian literature and apparently is written in late 7th century and early 8th century – if we accept to be written by khajooye kermani- is among these works which is similar to shahname f...

saqqā-ḵāna artists looked to cults, rituals, and visual elements of folk and local vernacular culture for inspiration. although many of these items appeared crude in their execution and lacked the artistic polish of artifacts made by professional calligraphers and painters, and were often created collaboratively as a kind of street art, their true significance was not lost to these artists. vie...

Currently, there are a number of motif detection tools available that possess unique functionality. These tools often report different motifs, and therefore use of multiple tools is generally advised since common motifs reported by multiple tools are more likely to be biologically significant. However, results produced by these different tools need to be compared and existing similarity detecti...

Noncanonical RNA motifs help define the vast complexity of RNA structure and function, and in many cases, these loops and junctions are on the order of only ten nucleotides in size. Unfortunately, despite their small size, there is no reliable method to determine the ensemble of lowest energy structures of junctions and loops at atomic accuracy. This chapter outlines straightforward protocols u...

Viroids are noncoding RNAs that infect plants. In order to establish systemic infection, these RNAs must traffic from an initially infected host cell into neighboring cells and ultimately throughout a whole plant. Recent studies have identified structural motifs in a viroid that are required for trafficking, enabling further studies on the mechanisms of their function. Some cellular proteins in...
