Abstract: This paper presents a coding approach for achieving omnidirectional transmission of certain common signals in massive multi-input multi-output (MIMO) networks such that the received power at ...

Getting good at LeetCode Java can feel like a puzzle sometimes, right? You see all these problems, and you’re not sure where ...

In 1919, physicist Theodor Kaluza hypothesized that extra dimensions might solve some outstanding problems in physics. And while we haven't found any evidence yet for anything outside our normal ...

The first actively managed exchange-traded fund share classes are one step closer to becoming a reality. Dimensional submitted its first request for ETF share classes on Thursday, Oct. 9, 2025. The ...

Abstract: Two-dimensional (2-D) array sets with good 2-D correlation properties have received considerable attention in wireless communication systems. This paper focuses on 2-D Z-complementary array ...

Researchers from the University of Hong Kong studying the structure of electrons in 2D materials have predicted new types of phase transitions that have yet to be seen in experiments Illustration of ...

A fringe new theory suggests that time is the fundamental structure of the physical universe, and space is merely a byproduct. According to Gunther Kletetschka, a geologist — not a physicist, you’ll ...

Here’s what you’ll learn in this story: Time might actually have 3 dimensions. But it also means that the space would actually be one-dimensional, instead of the three dimensions we’re familiar with.

In a groundbreaking experiment, researchers from Tsinghua University have proven that two-dimensional (2D) semiconductor materials can withstand the harsh conditions of space. The team, led by ...

In April 1982, Prof. Dan Shechtman of the Technion–Israel Institute of Technology made the discovery that would later earn him the 2011 Nobel Prize in Chemistry: the quasiperiodic crystal. According ...

Typically, an AI is "just" software. AI-powered software services like Grammarly and Rytr use neural nets, like GPT-3. Those neural nets consist of equations or commands, written in things like Python ...

Seniors and people who are immunocompromised should get not just one but two COVID-19 shots this respiratory virus season. That's the new recommendation from the U.S. Centers for Disease Control and ...
