Escherichia coli is the best-characterized organism with respect to posttranscriptional modifications of its ribosomal RNA (rRNA). It is presently believed that all the modified nucleotides have been identified, primarily on the basis of two detection methods; modification-induced inhibition of the enzyme reverse transcriptase or analysis by combined HPLC and electrospray ionization mass spectr...

• A novel video-based indirect measurement procedure for SHM projects. three-step modification process inappropriate conditions in video records. No need high-speed cameras and expensive record equipment. Experimental modal characteristics time history responses are the main outputs. Effective accurate field-measurement of historical structures. sensing dynamic identification purposes is presen...

In fracture mechanics and failure analysis, cracked media energy and consequently stress intensity factors (SIFs) play a crucial and significant role. Based on linear elastic fracture mechanics (LEFM), the SIFs and energy of cracked media may be estimated. This study presents the novel modification of decoupled scaled boundary finite element method (DSBFEM) to model cracked media. In this metho...

Model checking has been successfully applied to system verification. However, there are no standard and universal tools to date being applied for system modification. This paper introduces a formal approach called the Linear Temporal Logic (LTL) model update for system modification. In contrast to previous error repairing methods, which were usually simple program debugging and specialized tech...

A b s t r a c t In this paper, we briefly discuss the dynamic and functional approach to computer symbolic tensor analysis. The ccgrg package for Wolfram Language/Mathematica is used to illustrate this approach. Some examples of applications are attached.

In this article, we propose a fuzzy class relation assigning to each pair of finite fuzzy sets a degree to which they are equipollent, which indicates that they have the same number of elements. The concepts of fuzzy sets and fuzzy classes in the class of all countable sets are introduced, and several standard relations and constructions, such as the fuzzy power set and exponentiation, are defi...

the loss of the papilla can lead to cosmetic deformities, phonetic problems and lateral food impaction. several reasons con-tribute to the loss of interdental papillae and the establishment of “black triangles” between teeth. in 1996, han and takei proposed a novel approach based on the use of a semi-lunar incision placed in the alveolar mucosa of the interdental area. the present case report, ...

sulfur mustard (sm, bis- (2-chloroethyl) sulphide) is a chemical warfare agent that causes dna alkylation, protein modification and membrane damage. sm can trigger several molecular pathways involved in inflammation and oxidative stress, which cause cell necrosis and apoptosis, and loss of cells integrity and function. epigenetic regulation of gene expression is a growing research topic and is ...

This paper proposes an adaptive filter based prosody modification approach. It consists of three components, i.e., a frequency estimator, a pitch tracker and a prosody modifier. Firstly, the frequency estimator is applied to segment the speech signal into sentences and the maximum frequency level of each sentence is estimated. Then, the adaptive filter that is adapted according to the maximum f...
