Abstract: A simultaneous transmitting and reflecting reconfigurable array (STAR-RA) with independent beams is proposed in this communication. This STAR-RA can realize bidirectional beams ...

This video explains a challenging exponential equation step by step, showing how to simplify expressions, apply exponent rules, and solve systematically without skipping key logic. Perfect for ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By rethinking gravity and cosmic timelines, it could rewrite our ...

Engineers use techniques from Origami to design spacecraft components, medical robots and antenna arrays. Researchers have developed a system to explain the rules that govern some of these key ...

Understand how Bidirectional RNNs really work — from concept to equations, made digestible for learners. #RNN #BidirectionalRNN #DeepLearning Mexico's Sheinbaum blasts Trump admin's move: "completely ...

Most people’s experiences with polynomial equations don’t extend much further than high school algebra and the quadratic formula. Still, these numeric puzzles remain a foundational component of ...

Abstract: This article reviews simultaneous bidirectional signaling and its unique signal integrity challenges for die-to-die links: the near-end echo signal and the hybrid circuit required to remove ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly ...
