Integrating Phylogenomics and Biogeography of Spectracanthicus (Siluriformes: Loricariidae) Reveals Complex Evolutionary History in a Brazilian Shield Endemic Genus

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Loricariidae is the most diverse catfish family in the Neotropics. Within this group, the genus Spectracanthicus presents conflicting phylogenetic signals: morphological studies suggest monophyly, whereas previous molecular analyses often yield unresolved relationships and taxonomic uncertainty.

Loosely Synchronised Spreading Code Aided Network Performance of Quasi-Synchronous UTRA-like TDD and FDD CDMA Systems

open access: yes, 2005
It is demonstrated that loosely synchronised (LS) spreading codes exhibit a so-called interference-free window, where both the autocorrelation and cross-correlation of the codes become zero.

Enhancing the Seismic Resilience of Masonry‐Infilled RC Structures Using Rubber Joints: Full‐Scale 3D Shaking Table Tests

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 15, Page 4088-4112, December 2026.
ABSTRACT Masonry infills in reinforced concrete (RC) frames are highly vulnerable to seismic damage, often sustaining severe cracking even under moderate ground motion, which in turn leads to considerable economic losses and safety risks. To address this issue, this study experimentally evaluates the effectiveness of two innovative rubber‐based joints ...

Digital Cancellation of Passive Intermodulation in FDD Transceivers [PDF]

open access: yes2018 52nd Asilomar Conference on Signals, Systems, and Computers, 2018
Modern radio systems and transceivers utilize carrier aggregation (CA) to meet the demands for higher and higher data rates. However, the adoption of CA in the existing Long Term Evolution (LTE)-Advanced and emerging 5G New Radio (NR) mobile networks, in case of frequency division duplexing (FDD), may incur self-interference challenges with certain ...

Genomic characterization of a MAGIC population containing introgressions from four tetraploid Gossypium species

open access: yesThe Plant Genome, Volume 19, Issue 4, December 2026.
Abstract One strategy for increasing the genetic diversity of upland cotton (Gossypium hirsutum) involves the introgression of beneficial alleles from related and wild tetraploid species. Progress in this area has been limited due to undesirable outcomes associated with whole genome interspecific hybridization. To minimize genetic influences from other
