Minimum bit error rate multiuser transmission designs using particle swarm optimisation

, 2009
We consider the downlink of a multiuser system equipped with multiple antennas transmitting to multiple single-antenna mobile receivers. Particle swarm optimisation (PSO) is invoked to solve the constrained nonlinear optimisation problem for the minimum ...

Increased Genetic Instability in Exfoliated Oral Cells in Patients With Epidermolysis Bullosa

Oral Diseases, EarlyView.
ABSTRACT Objective To analyze the nuclear abnormalities of cytotoxicity—karyorrhexis (KR), karyolysis (KL), and pyknosis (PN)—and genotoxicity—micronucleus (MN) in exfoliated cells from different sites of the oral mucosa in patients with Epidermolysis Bullosa (EB) and a control group.

Arbuscular mycorrhizal fungal (AMF) communities in sand bars associated with Ipomoea pes‐caprae: a promising strategy for petroleum spill bioremediation in coastal dunes

Restoration Ecology, EarlyView.
Abstract Introduction Polycyclic aromatic hydrocarbons (PAHs), a class of petroleum‐derived compounds known for causing cellular damage and for their recalcitrant behavior, severely limit effective biodegradation. Arbuscular mycorrhizal fungi (AMF) from oil‐contaminated environments can mitigate PAH‐related stress on host plants, highlighting the ...

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 ...

Rising Incidence and Spatiotemporal Dynamics of Emerging and Reemerging Arboviruses in Brazil

Viruses
Background: Brazil has witnessed the co-circulation of dengue virus (DENV), Zika virus (ZIKV), and chikungunya virus (CHIKV), with outbreaks exacerbated by environmental factors, social determinants, and poor sanitation.

The Kalman Filtering Blind Adaptive Multi-user Detector Based on Tracking Algorithm of Signal Subspace

Information, 2015
Multi-user detection is an effective method to reduce multiple access interference in code division multiple access (CDMA) systems. This paper discusses a signal subspace based blind adaptive multiuser detector and a Kalman filtering blind adaptive ...

Multiuser Space–Time Line Code With Transmit Antenna Selection

IEEE Access, 2020
In this paper, a multiuser space-time line code (MU-STLC) scheme is newly designed that concurrently delivers multiple STLC signals to multiple users, and a preprocessing matrix for the MU-STLC is derived based on the minimum mean square error criterion.
