The DNA double helix was first elucidated by J.D. Watson and F.H.C. Crick over a half century ago. However, no one could actually “see” the well-known structure ever. Among all real-space observation ...

This paper presents a multi-axial force sensing system for haptic feedback of minimally invasive robotic surgery. The system consists of a 3-axial force sensor located on the wrist of surgical grasper ...

Nb/sub 3/Sn thin films were made by sputter deposition of Nb onto bronze substrates at various temperatures. Deposition at 660/spl deg/C produced a Nb/sub 3/Sn reaction immediately, which resulted in ...

Anisotropic intermolecular interactions of water at the liquid–vapor interface are investigated through calculations of the terahertz (THz) sum frequency generation (SFG) spectroscopy using a ...

The impact test on short concrete filled steel tubular column was conducted through DHR-9401 dropped hammer tester. Based on analysis on recorded time-history curve of impact force, the relations of ...
