The phenomenon of protein synthesis has been modeled in terms of totally asymmetric simple exclusion processes (TASEP) since 1968. In this article, we provide a tutorial of the biological and mathematical aspects of this approach. We also summarize several new results, concerned with limited resources in the cell and simple estimates for the current (protein production rate) of a TASEP with inh...

Our previous results [J.Phys.: Condens. Matter 14 (2002) 13777] dealing with the analytical solution of the two-dimensional (2-D) Anderson localization problem due to disorder is generalized for anisotropic systems (two different hopping matrix elements in transverse directions). We discuss the mathematical nature of the metalinsulator phase transition which occurs in the 2-D case, in contrast ...

In this paper a new kind of hopping robot has been designed which uses inverse pendulum dynamics to induce bipedal hopping gaits. Its mechanical structure consists of a rigid inverted T-shape mounted on four compliant feet. An upright “T” structure is connected to this by a rotary joint. The horizontal beam of the upright “T” is connected to the vertical beam by a second rotary joint. Using thi...

The nature of packet loss of wireless links at 2.4G band was analyzed and a wireless link quality prediction algorithm for wireless sensor networks was proposed. In the proposal, RSSI (Received Signal Strength Indicator) and LQI (Link Quality Indicator) were utilized to produce a couple of metrics of wireless link quality, named Sm and delta respectively, and their distributions were studied. B...

roasting has considerable effects on the quality of cream made of nuts. in this study, the roasting conditions of walnut kernels were optimized based on the stability parameters of the produced cream. temperatures of 100-150°c for 10-30 minutes were used to roast walnut kernels. the amount of oil separation, peroxide, acidity and thiobarbituric acid values of the cream, as well as color paramet...

the present study aimed to evaluate the antibiotic resistance pattern of escherichia coli strains isolatedfrom animals to ascertain the levels of antibiotic resistance pervasiveness. a total of 28 e. coli strains wereisolated from faecal samples and the antibiotic resistance pattern of e. coli strains was determined by meansof disc diffusion assay. the resistance pattern determined for all stra...

the sharp upper bounds and the sharp lower bounds of the largest eigenvalues $lambda_1$, the least eigenvalue $lambda_n$, the second largest eigenvalue $lambda_2$, the spread and the separator among all firefly graphs on $n$ vertices are determined.
