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.

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 ...

Rational acquisition of laboratory equipment: an accurate mathematical model to estimate the trade‐offs in shared and nonshared equipment

Acta Crystallographica Section D, Volume 82, Issue 6, Page 638-645, June 2026.
We present a quantitative framework combining cost modelling and queueing theory to estimate hourly access costs, waiting times and congestion levels for shared high‐end scientific equipment. The approach is general, illustrated with cryo‐electron microscopy examples, and implemented in an open‐access online calculator to support evidence‐based ...

Making the invisible visible: A global examination of careers and recognition for Imaging Scientists in core facilities

Journal of Microscopy, Volume 302, Issue 3, Page 274-294, June 2026.
Abstract Imaging facilities underpin a growing share of modern life‐science research, yet the career conditions and scholarly recognition of the Imaging Scientists in core facilities who design, deliver, and interpret imaging research remain uneven. This mismatch has previously been shown to risk loss of expertise, reduced service quality, and weaken ...

Fast Frequency-Hopping Dynamic Multiple-Access for Cognitive Radios: Suboptimum Noncoherent Maximum-Likelihood Multiuser Detection [PDF]

, 2010
We propose a novel dynamic multiple-access (DMA) scheme for application in cognitive radios (CRs). This DMA scheme is implemented by fast frequency hopping with $M$-ary frequency-shift keying (FFH/MFSK) associated with suboptimum noncoherent maximum ...

Intersymbol Decorrelating Detector for Asynchronous CDMA Networks with Multipath

EURASIP Journal on Wireless Communications and Networking, 2005
Most reported multiuser detection techniques for CDMA systems need the channel estimation including the delay spread and the parameters of the multipath channel of the desired user. This paper proposes an intersymbol decorrelating detector that makes use
