Convolutional-Neural-Network-Based Detection Algorithm for Uplink Multiuser Massive MIMO Systems

IEEE Access, 2020
In the coming 6th generation (6G) and beyond in wireless communication, an increasing number of ultrascale intelligent factors, including mobile robot users and smart cars, will result in interference exploitation.

Metaverse and Artificial Intelligence as Web 4.0: The Next Generation of the Internet

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This study utilizes systems thinking to explore and entwine an evolving metaverse scholarship to a relatively underexplored phenomenon of Web 4.0. We adopt a soft systems thinking framework to guide the interpretation of complex and evolving metaverse scholarship, using bibliometric mapping of 5587 publications sourced from Scopus.

Pharmacological inhibition of hydroxysteroid 11‐beta dehydrogenase type 1 (11‐βHSD1) after myocardial infarction preserves cardiac function in a translational mini‐pig model

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Plasma glucocorticoids increase acutely after MI, thereafter tissue levels are amplified selectively within cells expressing 11‐ßhydroxysteroid dehydrogenase type 1 (11‐ßHSD1) that regenerates active glucocorticoids from circulating metabolites.

SVD-Aided Beamforming and Power Allocation Algorithm for Multiuser Turbo-BLAST System Uplink with Imperfect CSI

International Journal of Antennas and Propagation, 2012
The SVD-aided joint transmitter and receiver design for the uplink of CDMA-based synchronous multiuser Turbo-BLAST systems is proposed in the presence of channel state information (CSI) imperfection.

Assessing Clinical Competence of Postgraduate Dental Specialty Trainees: A Scoping Review

European Journal of Dental Education, EarlyView.
ABSTRACT Background Assessment is essential to ensure that trainees meet competency standards in delivering patient care. However, a comprehensive summary of the literature on clinical assessment in postgraduate dental education is largely absent. Filling this gap is essential for developing effective assessment processes to help support competency ...

Exploiting Opportunistic Multiuser Detection in Decentralized Multiuser MIMO Systems [PDF]

GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009
This paper studies the design of a decentralized multiuser multi-antenna (MIMO) system for spectrum sharing over a fixed narrow band, where the coexisting users independently update their transmit covariance matrices for individual transmit-rate maximization via an iterative manner.

Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

Journal of Fish Diseases, EarlyView.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).

Rational Feelings for Virtual Things?

Philosophical Issues, EarlyView.
ABSTRACT This article examines the rationality of affective responses to virtual phenomena. I argue that at least some such responses can be perfectly rational, but that virtual realism and virtual irrealism—competing views about the metaphysics of the virtual—differ in their verdicts about the possible rationality of certain types of responses ...

Water availability shapes temporal patterns of extrafloral nectar secretion and ant visitation to a Neotropical legume

Plant Biology, EarlyView.
Drought duration affects ant–plant interactions: extrafloral nectar quality initially increases and subsequently declines, and ant interaction patterns closely track these nectar dynamics. Abstract Mutualistic plants use non‐structural sugar (NSC) to produce carbon‐based resources to reward partners.

Amacrine cell inputs to OFF midget ganglion cells in macaque retina

The Journal of Physiology, EarlyView.
Abstract figure legend The goal of this study was to explain the findings from physiological studies that OFF midget ganglion cells had larger receptive field centers than expected from their dendritic field diameters. First, we confirmed that OFF mRGCs (OFF MGC) receive input from diffuse bipolar cells (DB) as well as OFF midget bipolar cells (FMB ...
