Abstract Background Metal artifacts arising around high-density components are a widely known problem in X-ray computed tomography (XCT) for both medical and industrial applications. Although phase contrast imaging XCT (PCI-XCT) is to be less prone metal caused by beam hardening, so far only little effort was made its comparison other, more established methods. Objective In the course of this w...

Stone tools, or lithics, are the least familiar artifacts archaeologists encounter in our research. Most of us have more than a passing acquaintance with artifacts made of ceramics or metal. We have household words for them, such as “bowl” or “nail,” that transfer readily into archaeological analysis. Few students come to archaeology already familiar with stone tools. When and where preservatio...

A comprehensive analysis of the corrosion characteristics excavated bronze artifacts was conducted according to their alloy ratio and microstructure. Corroded by various factors, which resulted in different characteristics. Among these, may occur due difference ratio, is an internal factor. In this study, we tried confirm from Songguk-ri site Buyeo microstructure through a analysis. The differe...

Introduction: The use of orthopedic implants including joint replacements and fixation devices is increasingly common, necessitating follow-up evaluation to assess possible complications such as loosening or infection. Due to metal-induced distortion and other artifacts on conventional MRI, follow-up is often limited to Xray images. With additional encoding and parallel imaging, MR images with ...

 Brain-computer interfaces (BCI) record brain signals, analyze and translate them into control commands which are relayed to output devices that carry out desired actions. These systems do not use normal neuromuscular output pathways. Actually, the principal goal of BCI systems is to provide better life style for physically-challenged people which are suffered from cerebral palsy, amyotrophic l...
