Beamforming and precoding techniques [PDF]

open access: yesarXiv, 2020
Beamforming and precoding/combining are techniques aimed at processing multiantenna signals at the transmitter and/or at the receiver of a wireless communication system. While they have been routinely used to improve performance in current and previous generations of mobile communications systems, they are expected to play a more fundamental role in ...

A Copper‐Based Photothermal‐Responsive Nanoplatform Reprograms Tumor Immunogenicity via Self‐Amplified Cuproptosis for Synergistic Cancer Therapy

open access: yesAdvanced Science, EarlyView.
This study introduces cuproptosis nanoplatform, a novel nanoplatform using Cu2−XS hollow nanospheres, elesclomol, and lauric acid (LA) for self‐amplified cuproptosis. NIR‐II laser activation melts LA, releasing copper ions and elesclomol to enhance copper delivery within tumor cells, reduce glutathione's inhibitory effect, and trigger immunogenic cell ...

A Brief Overview of CRC Implementation for 5G NR

open access: yes, 2021
In fifth generation (5G) new radio (NR), the medium access control (MAC) layer organizes the data into the transport block and transmits it to the physical layer. The transport block consists of up to million bits. When the transport block size exceeds a threshold, the transport block is divided into multiple equal size code blocks.

Overcoming Extreme Ammonia Inhibition on Methanogenesis by Artificially Constructing a Synergistically Community with Acidogenic Bacteria and Hydrogenotrophic Archaea

open access: yesAdvanced Science, EarlyView.
This study proposes a two‐step biological strategy to synergistically enhance the three stages of anaerobic digestion, ultimately eliminating the extreme ammonia inhibition and breaking through the inefficiency bottleneck of conventional biotechnology.

Detecting the Difficult: An Intronic NPC1 Variant Hiding in Plain Sight

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT An illustration of the importance of manual data review for identifying rare intronic variants adjacent to homopolymers is presented here. A 14‐year‐old male with Niemann‐Pick Type C disease confirmed biochemically was only found to have a heterozygous pathogenic variant by molecular analysis. A manual review of the Next Generation Sequencing (

Selbstoptimierende Kobalt Wolframoxid Elektrokatalysatoren zur verbesserten Sauerstoffentwicklung in alkalischen Medien

open access: yesAngewandte Chemie, EarlyView.
Eine schrittweise verbesserte Sauerstoffentwicklung wird durch Selbstoptimierung von Kobaltwolframoxid erreicht, das auf einem im Labor synthetisierten Kupferoxidsubstrat abgeschieden wird. Experimentelle Daten belegen eine dynamische Entwicklung der Zusammensetzung/Struktur, während theoretische Berechnungen eine Anpassung der aktiven Stelle aufzeigen.
