Abstract: Machine-learning (ML)-assisted antenna-array design methods suffer from a heavy computational burden. In this article, a knowledge-guided active-base-element-modeling (KG-ABEM) method is ...
Abstract: This letter presents a 60-element single-layer rectangular radial line helical array (RLHA). A new probe is designed to achieve single-layer RLHAs with a higher number of elements, with ...
A new model rectifies the long-standing deficiencies of the electronegativity concept. Researchers from Skoltech have developed a simple, universal formula that accurately predicts the chemical ...
Some chemical elements, such as tungsten, react with only a handful of others. In contrast, oxygen and fluorine form stable compounds with nearly every element in the periodic table. A new model ...
Russia has lost more than one million soldiers since its full-scale invasion of Ukraine began nearly four years ago, according to a new report. The General Staff of Ukraine's Armed Forces claims that ...
