Genetic Algorithm Assisted Minimum Bit Error Rate Multiuser Detection in Multiple Antenna Aided OFDM

, 2004
The family of minimum bit error rate (MBER) multiuser detectors (MUD) is capable of outperforming the classic minimum mean-squared-error (MMSE)MUDin term of the achievable bit-error rate (BER) owing to directly minimising the BER cost function.

Assessing the Impact of Wastewater Flow Rates on SARS‐CoV‐2 RNA Detection: Insights for Environmental Surveillance and Policymaking

Environmental Quality Management, Volume 35, Issue 4, Summer 2026.
We meta‐analyzed 10 studies to assess whether influent flow rate affects SARS‐CoV‐2 RNA detection in wastewater treatment plants serving ≤60,000 inhabitants. The pooled odds ratio (2.08; 95% CI: 0.994–37; p = 0.053) showed no significant association between flow rate and detection probability.

Impact of 2D versus 3D fibroblast models on Leishmania species invasion in vitro: Rab5 dynamics and actin activity in initial infection

Frontiers in Cellular and Infection Microbiology
BackgroundThe protozoan Leishmania, in addition to infecting phagocytic cells such as macrophages, can also invade non-professional phagocytic cells like fibroblasts, a process previously described in 2D models.

Strategic Roadmap for Addressing Microplastic Pollution in the Global South: Bridging Monitoring Gaps, Harmonizing Methods, and Building Analytical Capacity

Environmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Microplastic (MP) pollution represents a growing environmental challenge, especially in tropical and subtropical coastal regions of the Global South, where methodological fragmentation, funding discontinuity, and dependence on external analytical infrastructure limit the production of comparable data and the formulation of evidence‐based ...

Computational Insights into the Interaction of the Conserved Cysteine-Noose Domain of the Human Respiratory Syncytial Virus G Protein with the Canonical Fractalkine Binding site of Transmembrane Receptor CX3CR1 Isoforms

Membranes
The human Respiratory Syncytial Virus (hRSV) stands as one of the most common causes of acute respiratory diseases. The infectivity of this virus is intricately linked to its membrane proteins, notably the attachment glycoprotein (G protein).

Adaptive near minimum error rate training for neural networks with application to multiuser detection in CDMA communication systems

, 2005
Adaptive training of neural networks is typically done using some stochastic gradient algorithm that tries to minimize the mean square error (MSE). For many applications, such as channel equalization and code-division multiple-access (CDMA) multiuser ...

Antenna-Diversity-Assisted Genetic-Algorithm-Based Multiuser Detection Schemes for Synchronous CDMA Systems

, 2003
A spatial diversity reception assisted multiuser code-division multiple-access detector based on genetic algorithms (GAs) is proposed. Two different GA-based individual-selection strategies are considered. In our first approach, the so-called individuals
