Sex‐specific associations of Roseburia with uric acid metabolism and hyperuricemia risk in females

iMetaOmics, EarlyView.
Researchers recruited 623 participants, including 270 females, and used 16S rDNA sequencing to investigate gender differences in hyperuricemia. In healthy females, Roseburia was enriched, positively correlating with estrogen and negatively with uric acid, suggesting it is a potential biomarker affecting uric acid levels in females.

A High-Efficiency Spectral Method for Two-Dimensional Ocean Acoustic Propagation Calculations

Entropy, 2021
The accuracy and efficiency of sound field calculations highly concern issues of hydroacoustics. Recently, one-dimensional spectral methods have shown high-precision characteristics when solving the sound field but can solve only simplified models of ...

Optical Character Recognition of 19th Century Classical Commentaries: the Current State of Affairs [PDF]

arXiv, 2021
Together with critical editions and translations, commentaries are one of the main genres of publication in literary and textual scholarship, and have a century-long tradition. Yet, the exploitation of thousands of digitized historical commentaries was hitherto hindered by the poor quality of Optical Character Recognition (OCR), especially on ...

KRAKEN: A Novel Semantic-Based Approach for Keyphrases Extraction

International Joint Conference on Artificial Intelligence, 2022
We propose KRAKEN, a novel approach for the extraction of keyphrases from texts. To this aim, KRAKEN makes use of distributional semantics to identify, as completely as possible, representative portions of documents, i.e. keyphrases.

Commensurate Spin Density Wave in LaOFeAs: A Local Probe Study [PDF]

Phys. Rev. Lett. 101, 077005 (2008), 2008
We present a detailed study on the magnetic order in the undoped mother compound LaOFeAs of the recently discovered Fe-based superconductor LaO$_{1-x}$F$_x$FeAs. In particular, we present local probe measurements of the magnetic properties of LaOFeAs by means of $^{57}$Fe M\"ossbauer spectroscopy and muon spin relaxation in zero external field along ...

The tentacles of surveillance: Cephalopods and United States satellite intelligence

Journal for the Anthropology of North America, EarlyView.
Abstract This article examines the symbol placed on a US spy satellite, National Reconnaissance Office Launch–39 (NROL‐39). In 2013, NROL‐39 was launched into space, the payload vehicle and mission patch emblazoned with a gigantic octopus, its tentacles surrounding the globe, and the words “Nothing Is Beyond Our Reach” written below the globe.

Deconvolution of JWST/MIRI Images: Applications to an Active Galactic Nucleus Model and GATOS Observations of NGC 5728

The Astronomical Journal
The superb image quality, stability, and sensitivity of JWST permit deconvolution techniques to be pursued with a fidelity unavailable to ground-based observations. We present an assessment of several deconvolution approaches to improve image quality and

SEPATH: benchmarking the search for pathogens in human tissue whole genome sequence data leads to template pipelines

Genome Biology, 2019
Background Human tissue is increasingly being whole genome sequenced as we transition into an era of genomic medicine. With this arises the potential to detect sequences originating from microorganisms, including pathogens amid the plethora of human ...

Metaproteomic Profiling of the Secretome of a Granule‐forming Ca. Accumulibacter Enrichment

PROTEOMICS, EarlyView.
ABSTRACT Extracellular proteins are supposed to play crucial roles in the formation and structure of biofilms and aggregates. However, often little is known about these proteins, in particular for microbial communities. Here, we use two advanced metaproteomic approaches to study the extracellular proteome in a granular Candidatus Accumulibacter ...
