Information Rate Decomposition for Noisy Nanopore Channels with Geometric Duplication
arXiv:2606.06808v1 Announce Type: new Abstract: This paper studies information rates of noisy duplication channels with memory, motivated by nanopore DNA sequencing. In nanopore sequencing, the measured signal is affected by both inter-symbol interference (ISI), caused by multiple DNA bases residing in the pore, and random sample duplications, where variable translocation speed causes each base to generate a random number of samples.
Nanopore Direct RNA Sequencing Enables Reproducible, Site-Resolved Pseudouridine Quantification in Human Ribosomal RNA
Pseudouridine is the most abundant post-transcriptional modification in human ribosomal RNA, with over 110 annotated sites and variable stoichiometry across biological contexts. Existing quantification methods are low-throughput or constrained to predefined panels. We benchmarked nanopore direct RNA sequencing using the Dorado v5.1 model against mass spectrometry-validated sites in human liver tissue, induced pluripotent stem cells, and HeLa cells.
High-accuracy hierarchical rRNA operon profiling resolves genomovar-level taxonomy and microdiversity using Nanopore sequencing.
Genomovar-level and intragenomic diversity cannot be resolved by conventional amplicon sequencing due to the limitation of fragment lengths and read accuracy, while the application of metagenomic profiling to a large number of samples can be resource intensive. Here, we report UltraRes-rrn, an integrated wet-lab and computational workflow for high-accuracy rrn (i.e., 16S-ITS-23S rRNA) operon profiling using Nanopore sequencing. By integrating ultra-long DNA recovery, long-read amplicon...
Persistent circulation of Rift Valley fever virus lineage C in Rwanda, 2022-2025
Rwanda has experienced recurrent Rift Valley fever virus outbreaks in the last decade. In this study, we investigated whether these outbreaks resulted from repeated introductions or sustained local circulation. We generated RVFV whole-genome sequences from livestock samples collected between 2022 and 2025 using Nanopore sequencing.
Epigenetic Patterns of Xylanibacter ruminicola in Bovine Rumen Across Seasons and Pregnancy
Ruminants obtain nutrients through the microbial fermentation of plant material in the rumen. Xylanibacter ruminicola is a highly abundant bacterial species in the rumen. During fermentation, X. ruminicola utilizes diverse carbohydrates from plant materials to synthesize propionate, a volatile fatty acid providing energy to ruminants.
Multihospital expansion of vancomycin-resistant Enterococcus faecium ST117-CT7799 and transmission of linear plasmids co-carrying vanA and linezolid resistance genes, Comunitat Valenciana, Spain (2022-2024)
Background: Vancomycin-resistant Enterococcus faecium (VREfm) is a WHO priority pathogen. In the Comunitat Valenciana (CV), Spain, VREfm prevalence has increased since 2022. We characterized the population structure, transmission patterns and resistance determinants of VREfm across eight hospitals (2021-2024).
A Low-Cost, High-Throughput Design-Build-Test Pipeline for Engineering Genetic Systems: Stress Testing with Complex Structural Proteins
Genetic systems engineering is constrained by high DNA synthesis costs, assembly inefficiencies, and challenges in expressing complex proteins. To address these limitations, we developed a highly parallel, low-cost pipeline for the design, assembly, and functional screening of genetic systems, which we stress-tested on highly repetitive structural proteins, including spider silk, biocements, reflectins, and talins. The integrated pipeline combines computational genetic systems design,...
Light-induced quantum friction of carbon nanotubes in water
Abstract Friction slows down moving objects at both macroscopic and microscopic scales1. At the electronic level, quantum friction describes direct transfer of momentum between a liquid and the electrons of a solid2. Owing to its microscopic nature, this phenomenon remains experimentally challenging to capture3.
