in this paper, a rectangular sandwich plate with a constrained layer and an electrorheological (er) fluid core is investigated. the rectangular plate is covered an er fluid core and a constraining layer to improve the stability of the system. the two outer layers of the sandwich structure are elastic. the viscoelastic materials express the middle layer behavior under electric field and small st...

Oxaliplatinium is an anticancer drug, used in chemotherapy. To investigate the oxaliplatinium structure based on frontier orbital analysis, thermodynamic analysis and natural bond orbital (NBO) theory is the main objective of the present research. The calculated HOMO and LUMO energies show that charge transfer occurs within molecule. The NBO charges, the values of electric dipole moment (µ) of ...

AC electric fields induce redistribution of integral membrane proteins. Cell-surface receptor redistribution does not consistently follow electric field lines and depends critically on the frequency of the applied ac electric fields, suggesting that mechanisms other than electroosmosis are involved. We hypothesized that cytoskeletal reorganization is responsible for electric field-induced cell-...

We study the behavior of single linear polyelectrolytes condensed by trivalent salt under the action of electric fields through computer simulations. The chain is unfolded when the strength of the electric field is stronger than a critical value. This critical electric field follows a scaling law against chain length, and the exponent of the scaling law is -0.77(1), smaller than the theoretical...

In this paper, timbre of stringed instrument is analyzed and the timbre sound is synthesized. Timbre is familiar and looks well known, but it has been unknown even now what an essential factor is. And it is the most important factor for human to distinguish sounds with the same duration, loudness and pitch. The formant structure model for keeping the same timbre is proposed in this paper. The s...
