Variation in foraging activity influences area-restricted search behaviour by bottlenose dolphins
<p>Area-restricted search (ARS) behaviour is commonly used to characterise spatio-temporal variation in foraging activity of predators, but evidence of the drivers underlying this behaviour in marine systems is sparse. Advances in underwater sound recording techniques and automated processing of acoustic data now provide opportunities to investigate these questions where species use different vocalisations when encountering prey. Here, we used passive acoustics to investigate drivers of ARS behaviour in a population of dolphins, to determine if residency in key foraging areas increased following encounters with prey. Analyses were based on two independent proxies of foraging: echolocation buzzes (widely used as foraging proxies), and bray calls (vocalizations linked to salmon predation attempts). Echolocation buzzes were extracted from echolocation data loggers and bray calls from broadband recordings by a convolutional neural network (CNN). We found a strong positive relationship between the duration of encounters and the frequency of both foraging proxies, supporting the theory that bottlenose dolphins engage in ARS behaviour in response to higher prey encounter rates. This study provides empirical evidence for one driver of ARS behaviour and demonstrates the potential for applying passive acoustic monitoring in combination with deep learning-based techniques to investigate the behaviour of vocal animals. </p>
MetaPep: A core peptide database for faster human gut metaproteomics database searches
<p>Metaproteomics has increasingly been applied to study functional changes in the human gut microbiome. And peptide identification is an important step in metaproteomics research. However, the large search space in metaproteomics studies causes significant challenges for peptide identification. Here, we constructed MetaPep, a core peptide database (including both collections of peptide sequences and tandem MS spectra) greatly accelerating the peptide identifications. Raw files from fifteen metaproteomics projects were re-analyzed and the identified peptide-spectrum matches (PSMs) were used to construct the MetaPep database. The constructed MetaPep database achieved rapid and accurate identification of peptides for human gut metaproteomics.</p>
The second data release from the European Pulsar Timing Array III. Search for gravitational wave signals
<p>We present the results of the search for an isotropic stochastic gravitational wave background (GWB) at nanohertz frequencies using the second data release of the European Pulsar Timing Array (EPTA) for 25 millisecond pulsars and a combination with the first data release of the Indian Pulsar Timing Array (InPTA). A robust GWB detection is conditioned upon resolving the Hellings-Downs angular pattern in the pairwise cross-correlation of the pulsar timing residuals. Additionally, the GWB is expected to yield the same (common) spectrum of temporal correlations across pulsars, which is used as a null hypothesis in the GWB search. Such a common-spectrum process has already been observed in pulsar timing data. We analysed (i) the full 24.7-year EPTA data set, (ii) its 10.3-year subset based on modern observing systems, (iii) the combination of the full data set with the first data release of the InPTA for ten commonly timed millisecond pulsars, and (iv) the combination of the 10.3-year subset with the InPTA data. These combinations allowed us to probe the contributions of instrumental noise and interstellar propagation effects. With the full data set, we find marginal evidence for a GWB, with a Bayes factor of four and a false alarm probability of 4%. With the 10.3-year subset, we report evidence for a GWB, with a Bayes factor of 60 and a false alarm probability of about 0.1% (≳ 3σ significance). The addition of the InPTA data yields results that are broadly consistent with the EPTA-only data sets, with the benefit of better noise modelling. Analyses were performed with different data processing pipelines to test the consistency of the results from independent software packages. The latest EPTA data from new generation observing systems show non-negligible evidence for the GWB. At the same time, the inferred spectrum is rather uncertain and in mild tension with the common signal measured in the full data set. However, if the spectral index is fixed at 13/3, the two data sets give a similar amplitude of (2.5 ± 0.7) × 10−15 at a reference frequency of 1 yr−1 . Further investigation of these issues is required for reliable astrophysical interpretations of this signal. By continuing our detection efforts as part of the International Pulsar Timing Array (IPTA), we expect to be able to improve the measurement of spatial correlations and better characterise this signal in the coming years.</p>

A Unified pastro for Gravitational Waves: Consistently Combining Information from Multiple Search Pipelines
<p>This repository is made to contain the data products released with the paper " <a href="https://arxiv.org/abs/2305.00071">A Unified p-astro for Gravitational Waves: Consistently Combining Information from Multiple Search Pipelines</a>". In this paper, we showed how information from multiple GW pipelines can be combined to calculate a single probability of astrophysical origin - p-astro for GW triggers. This repository contains the joint probability distributions trained using injection (simulated signal) and noise triggers from the PyCBC and gstLAL pipelines from the O3 observing run of LIGO and Virgo. Using these distributions, a unified p-astro can be calculated for the on-source triggers from GWTC-2.1, as we show in the paper. </p><p>If you would like to download all files on this page, we recommend <a href="https://gitlab.com/dvolgyes/zenodo_get)">zenodo_get</a>:</p><p>pip install zenodo_get zenodo-get RECORD_ID_OR_DOI</p><p> </p><p>There are two data products in this repository.</p><p>1. A text file "pastro_calcs.txt" which has the unified p-astro of all triggers from GWTC-2.1</p><p>2. A pickle file containing the injection KDEs and the noise distribution files, along with the values of the normalization constants for the various cases.</p><p> </p><p>The pickle file can be read in python by,</p><p>import pickle pdf = pickle.load(open('zenodo_pdf.pickle', 'rb'))</p><p> </p><p>The injection KDEs were created using search pipelines run on simulated signals done by the LIGO-Virgo-KAGRA collaboration.
