This paper proposes a three-layered co-running track model for predicting and analysing the dynamic behaviour of railway turnouts during passage trains. It is multi-body with space-dependent parameters. The method demonstrated by applying UIC60-760-1:15 turnout (with curve radius 760 m angle 1:15). Equivalent properties are introduced, based on flexibility, rail receptance impact force results ...

The conformation of the anticodon stem-loop of tRNAs required for correct decoding by the ribosome depends on intramolecular and intermolecular interactions that are independent of the tRNA nucleotide sequence. Non-bridging phosphate oxygen atoms have been shown to be critical for the structure and function of several RNAs. However, little is known about the role they play in ribosomal A site b...

Systematic local structural studies of the Ba(1-x)K(x)Fe(2)As(2) system are undertaken at room temperature using atomic pair distribution function analysis. The local structure of the Ba(1-x)K(x)Fe(2)As(2) is found to be well described by the long-range structure extracted from diffraction experiments, but with anisotropic atomic vibrations of the constituent atoms (U11 = U22 not equal U33). Th...

To meet the increasing needs of modern heavy ion accelerators, ECR ion source must be developed to deliver high intensity high brightness high charge state ion beams, in terms of accelerator output power and beam transmission efficiency. With the success in several laboratories on fully superconducting ECR ion source development, the performance of highly charged heavy ion beams have been great...

This paper presents a research study of expected precipitation extremes across the Gandaki Province, Nepal. The used five indices to assess extreme under climate change. Precipitation output two Global Climate Models (GCMs) Coupled Model Intercomparison Project Phase Six (CMIP6) were characterize future during rainfall season from June September (JJAS) and overall days year. To events, we daily...

This study seeks to compare fixed-field intensity-modulated radiation therapy (FF IMRT), RapidArc (RA), and helical tomotherapy (HT) to discover the optimal treatment modality to deliver SBRT to the peripheral lung. Eight patients with peripheral primary lung cancer were reviewed. Plans were prescribed a dose of 48 Gy and optimized similarly with heterogeneity corrections. Plan quality was asse...
