Abstract: A 1×2 antenna array with three-parameter independently controllable reconfiguration of polarization, frequency and radiation pattern is proposed. One C-shaped slot and two PIN diodes are ...

Sea mollusc shells are patterned not through conscious control, but by chemistry acting at the shell’s growing edge. A thin strip of tissue known as the mantle secretes both the shell material and its ...

Cuttlefish attract prospective sexual partners by creating a pattern on their skin, based on the orientation of light waves. By Kate Golembiewski Many of the snazziest decorations in the animal ...

The Thread Modeler tool has been developed to allow Autodesk Inventor users to generate a realistic modeled equivalent thread based on an existing Inventor thread feature. Users are able to select an ...

The creation of artistic-pattern pendants using resin is a craft activity that involves color mixing, molding, and surface finishing to produce accessories with unique and visually appealing designs ...

Earth's water may contain atoms that originated from icy interstellar dust billions of years before the planet existed, according to new research. Credit: NSF / AUI / NSF NRAO / P. Vosteen / B. Saxton ...
