The recent deluge of new RNA structures, including complete atomic-resolution views of both subunits of the ribosome, has on the one hand literally overwhelmed our individual abilities to comprehend the diversity of RNA structure, and on the other hand presented us with new opportunities for comprehensive use of RNA sequences for comparative genetic, evolutionary and phylogenetic studies. Two c...
Pre-historic pottery investigating is one of the sources that provide a lot of information about the life and art of that time. Among Iranian arts, Pottery is of a greater antiquity, originality and importance and represents people’s culture, beliefs and traditions more than any other art. After basket weaving, pottery has been the first lasting art of mankind. By investigating earthenware moti...
Within traditional Islamic geometric design, there is a small but distinct subset of patterns which incorporate notions of self-similarity. Such patterns typically use exactly two overlapping levels of self-similarity, with each level comprising similar motifs at two different, related scales. Recently I have constructed a large number of fractal Islamic patterns that pursue a different notion ...
Most of the hairpin, internal and junction loops that appear single-stranded in standard RNA secondary structures form recurrent 3D motifs, where non-Watson-Crick base pairs play a central role. Non-Watson-Crick base pairs also play crucial roles in tertiary contacts in structured RNA molecules. We previously classified RNA base pairs geometrically so as to group together those base pairs that ...
We present a study of the transitional pathways between high-symmetry structural motifs for AgAu nanoparticles, with a specific focus on controlling the energetic barriers through chemical design. We show that the barriers can be altered by careful control of the elemental composition and chemical arrangement, with core@shell and vertex-decorated arrangements being specifically influential on t...
The textile of the Bakhtiarian's nomadic have many changes during of periods .This alterations will have continued, but some of that ,have a collection of designs that come from the mind of Bakhtiarian woman ,who teach them from her deceased, these study tried to collect the motifs that have many unknown meanings. The aim of this research is to introduce these motifs and try to field study. But...
ABSTRACT The Romanelli Cave in south-east Italy is an important reference point for the so-called ‘Mediterranean province’ of European Upper Palaeolithic art. Yet, site has only recently been subject to a systematic investigation its parietal and portable Starting 2016, project recorded cave's interior, discovering new Here, authors report on selection panels, featuring animal figures, geometri...
The design of rug and carpets (kilim) have artistic values and capacities which are not known enough for the artists and scholars. As some of such motifs belonging to the carpets of the city of Jiroft have been extracted by the creative mind of artist without any direct connection with the nature, this paper focuses on such motifs which are similar to natural elements in their visual repr...
To understand the hierarchical self-organization behaviors of soft materials as well as their dependence on molecular geometry, a series of AB n dendron-like molecules based on polyhedral oligomeric silsesquioxane (POSS) nanoparticles were designed and synthesized. The apex of these molecules is a hydrophilic POSS cage with 14 hydroxyl groups (denoted DPOSS). At its periphery, there are differe...
Corresponding Author: Fikri Budiman Department of Computer Science, University of Dian Nuswantoro, Semarang, Indonesia Email: [email protected] Abstract: Image retrieval using Support Vector Machine (SVM) classification very depends on kernel function and parameter. Kernel function used by dot product substitution from old dimension feature to new dimension depends on image dataset ...
