Shape Tools is a collection of geodesic tools that are installed in the Vector menu, on the toolbar, in the field calculator, or in the Processing Toolbox. Geodesic is the shortest path between two ...
A versatile wildlife lens for photographing a variety of subjects near and far, but its maximum aperture will slow you down in low light. Still, for the money, it's an excellent lens. Why you can ...
Scientists at Duke-NUS Medical School have developed two powerful computational tools that could transform how researchers study the "conversations" between cells inside the body. The tools, called ...
Although the team ultimately built a physical cloaking device, their work began in the theoretical realm. Mathematical modeling and physics-based simulations formed the first step in the research ...
Abstract: A compact high-DC-to-RF-efficiency push-push Colpitts voltage-controlled oscillator (VCO) operating at 190 GHz is proposed. By introducing a second-harmonic quarter-wavelength open-circuited ...
