barrel vaults are attractive space structures that cover large area without intermediate supports. in this paper, the charged search system (css) optimization algorithm is employed for optimal design of barrel vaults. this method utilizes the governing laws of coulomb and gauss from electrostatics and the newtonian law of mechanics. the results demonstrate the efficiency of the discrete css alg...

this paper consists of three sections. in the first section an efficient method is used for decomposition of the canonical matrices associated with repetitive structures. to this end, cylindrical coordinate system, as well as a special numbering scheme were employed. in the second section, divide and conquer method have been used for eigensolution of these structures, where the matrices are in ...

Vaults are the largest ribonucleoprotein particles found in eukaryotic cells, with an unclear cellular function and promising applications as vehicles for drug delivery. In this article, we examine the local stiffness of individual vaults and probe their structural stability with atomic force microscopy under physiological conditions. Our data show that the barrel, the central part of the vault...

This paper presents an improved magnetic charged system search (IMCSS) and open application programming interface (OAPI) for optimization of double layer barrel vaults. In IMCSS algorithm, magnetic charged system search (MCSS) and an improved scheme of harmony search (IHS) are utilized and some of the most important parameters in the convergence rate of HS scheme are improved to achieve a good ...

Introduction The 110 kDa major vault protein (MVP) represents the main component of evolutionary highly conserved ribonucleoprotein particles called vaults and accounts for 70% of the total particle mass (Mossink et al., 2003). Vaults are barrel-shaped structures with a hollow interior. They are composed of multiple copies of three proteins and small, untranslated vault RNAs. Vaults were found ...

Tensegrity structures have a high degree of indeterminacy. Occurrence initial partial failure at one point these can lead to the propagation throughout structure. One influential factors in is starting failure. The first occur member that considered as "critical member" and causes further damage structure, or it has caused minor structure maintain overall stability Identification critical membe...

Vaults are evolutionary highly conserved ribonucleoproteins particles with a hollow barrel-like structure. The main component of vaults represents the 110 kDa major vault protein (MVP), whereas two minor vaults proteins comprise the 193 kDa vault poly(ADP-ribose) polymerase (vPARP) and the 240 kDa telomerase-associated protein-1 (TEP-1). Additionally, at least one small and untranslated RNA is ...
