Recent physics studies have found that light can sometimes flow in unexpected ways, behaving like a so-called "superfluid." ...
Propagation-based phase-contrast X-ray computed tomography is a valuable tool for high-resolution visualization of biological samples, giving distinct improvements in terms of contrast and dose ...
NIST, Sandia National Laboratories, and International SEMATECH are developing a new type of linewidth standard for calibrating Critical Dimension (CD) metrology instruments for lithographic process ...
All three contrast-enhanced (CE) phases (e.g., Arterial, Portal Venous, and Delay) are crucial for diagnosing liver tumors. However, acquiring all three phases is constrained due to contrast agents ...
The source medical images are first transformed by NSCT followed by combining low- and high-frequency components. Two different fusion rules based on phase congruency and directive contrast are ...
Ionospheric dispersion will introduce quadratic and cubic phase error into spaceborne P-band ultrawideband synthetic aperture radar (SAR) signals, causing range ...
