Abstract: Water-filling (WF) algorithms are pivotal in maximizing capacity and spectral efficiency in multiple-input and multiple-output (MIMO) systems. However, traditional WF approaches cater solely ...

She tells people her boyfriend’s name is Spruce, but no one has ever met him. Not even her. Spruce, it turns out, is not a person but an artificial intelligence chatbot and one of the available voices ...

PINOLE, Calif. (KGO) -- You should check your bank statement if you bought gas at a 7-Eleven in the past week. A computer glitch has led customers to be overcharged "100 times" what they should have ...

Hackers are exploiting a new, undocumented vulnerability in the implementation of the cryptographic algorithm present in Gladinet's CentreStack and Triofox products for secure remote file access and ...

Abstract: By deploying a large number of antennas with sub-half-wavelength spacing in a compact space, dense array systems (DASs) can fully unleash the multiplexing and diversity gains of limited ...

The original version of this story appeared in Quanta Magazine. Imagine a town with two widget merchants. Customers prefer cheaper widgets, so the merchants must compete to set the lowest price.

Abstract: The role of differential equations (DEs) in science and engineering is of paramount importance, as they provide the mathematical framework for a multitude of natural phenomena. Since quantum ...

All of modern mathematics is built on the foundation of set theory, the study of how to organize abstract collections of objects. But in general, research mathematicians don’t need to think about it ...

Quantum computers are coming. And when they arrive, they are going to upend the way we protect sensitive data. Unlike classical computers, quantum computers harness quantum mechanical effects — like ...

On the premise of solving the problem in a specific situation, this paper aims at the laser marking machine to design and optimize the outline extraction of the two-dimensional composite curve figure ...
