A gradient metasurface wall structure operating in Ka-band is proposed. To reduce mutual coupling, side metallic walls with a designed metasurface arrays are incorporated into both sides of the unit ...

Microwave satellite data are key to capturing major changes in a hurricane’s strength, such as when a storm undergoes rapid ...

For generations, a popular belief has held that the Great Wall of China is the only human-made marvel visible from space. But ...

Abstract: The two-dimensional structure of the 90 degrees domain wall is computed by numerically minimizing the total wall energy. The method is similar to the one used for computing the structure of ...

Total export volumes of rare-earth magnets from China fell 74% in May from a year earlier, according to a Wall Street Journal analysis of Chinese customs data. That was the biggest percentage ...

β-Lactam antibiotics have long been a treatment of choice for bacterial infections since they bind irreversibly to Penicillin-Binding Proteins (PBPs), enzymes that are vital for cell wall biosynthesis ...

Covering over 40,000 hectares, and constructed from wood and metal with plastic sheeting, this is the largest structure visible from space ...

The effect of temperature on the structure of the rat odorant-binding protein was investigated by spectroscopic and in silico methodologies. In particular, in this work, we examined the structural ...
