Uncharged tRNA error damping model

Depletion of Saccharomyces cerevisiae tRNA Guanylyltransferase Thg1p Leads to Uncharged tRNA with Additional mC

Stringent factor from Escherichia coli directs ribosomal binding and release of uncharged tRNA.

Uncharged tRNA is preferentially bound to the peptidyl site of the ribosome in the absence of stringent factor ,but in its presence is directed to the acceptor site. The synthesis of pppGpp and ppGpp is initiated by tRNA bound in the acceptor but not in the peptidyl site. In this reaction, tRNA is not permanently attached to the acceptor site. Uncharged [32P] tRNA but not 3H-labeled stringent f...

Damping of Crank-Nicolson error oscillations

The Crank-Nicolson (CN) simulation method has an oscillatory response to sharp initial transients. The technique is convenient but the oscillations make it less popular. Several ways of damping the oscillations in two types of electrochemical computations are investigated. For a simple one-dimensional system with an initial singularity, subdivision of the first time interval into a number of eq...

Extended Rayleigh Damping Model

In dynamic analysis, frequency domain analysis can be used if the entire structure is linear. However, time history analysis is generally used if non-linear elements are present. Rayleigh damping has been widely used in time history response analysis. Many articles have reported the problems associated with this damping and suggested remedies. A basic problem is that the frequency area across w...

Identification of Damping from Experimental Dynamic Stiffness Matrix: Error Analysis

Some practical issues related to application of the dynamic stiffness matrix (DSM) based damping identification method to real life mechanical systems are studied in this paper. The DSM based direct damping matrix identification method was proposed to identify both the mechanism and spatial distribution of damping as a matrix of general function of frequency. The method obtains the damping matr...
