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 ...

Engineering Reports, Volume 8, Issue 6, June 2026.This paper proposes a dynamic search cluster head selection method for resource occupancy protection switching. By integrating multidimensional fitness functions, energy consumption models, and closed‐loop control mechanisms, and combining optimized dynamic search strategies, the optimal cluster head is selected.

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.

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 ...

The Worst-Case Interference in DSL Systems Employing Dynamic Spectrum Management
EURASIP Journal on Advances in Signal Processing, 2006 Dynamic spectrum management (DSM) has been proposed to achieve next-generation rates on digital subscriber lines (DSL). Because the copper twisted-pair plant is an interference-constrained environment, the multiuser performance and spectral ...

Dental Traumatology, Volume 42, Issue 3, Page 399-406, June 2026.ABSTRACT Background/Aim Bi‐colored mouthguards (MTG) are often sought by both professional and amateur athletes. Bi‐colored MTG can be made in the dental office from premanufactured bi‐colored EVA sheets or custom‐designed in the dental office for greater color variety.

A Multiuser Detection Algorithm in the Uplink SC-FDMA System for Green Communication Network
IEEE Access, 2016 The Single-carrier Frequency-Division Multiple Access (SC-FDMA) communication scheme is the key technique in green communications and networking for 5G for the uplink of SC-FDMA multiuser systems due to frequency differences introducing access ...

Iterative algorithm for interference alignment in multiuser mimo interference channels [PDF]
2010 IEEE 11th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2010 Algorithms for designing beamforming matrices for interference alignment in multiuser time-invariant multi-input multi-output interference channels are proposed. Based on a new formulation for the necessary and sufficient condition for interference alignment, the proposed algorithm iteratively minimizes overall interference misalignment in a least ...

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 ...
