Aphidinae comparative genomics resource
<p>Here we provide early access to 18 new genome assemblies, including 8 assembled to chromosome-scale, for aphids from the subfamily Aphidinae. For consistency and to aid comparative analysis, all genomes have been annotated using the same repeat masking and RNA-seq-based gene prediction pipeline. Using this pipeline we also provide new annotations for three previously published genome assemblies.</p> <p>The genome assemblies and annotations are made freely available without restriction, we only request that this Zenodo resource is cited when using the data. Raw sequence data upload to NCBI is underway and full details of all accessions will be given in an updated version of this resource. Manuscripts are in preparation describing the individual genome assemblies in detail and larger comparative genome analyses and we will update this resource with additional citation information as papers are published.</p> <p>Full details of all genome assemblies and annotations included in this release are given in the attached "Data_Description.pdf" document. </p> <p><strong>Aphid species included in this release (bold type = chromosome-scale assembly):</strong></p> <p><em><strong>Aphis fabae</strong><br> Aphis glycines </em>(updated annotation)<br> <em><strong>Aphis gossypii</strong><br> Aphis thalictri<br> Aphis rumicis<br> Brachycaudus cardui<br> Brachycaudus helichrysi<br> Brachycaudus klugkisti<br> <strong>Brevicoryne brassicae</strong><br> Diuraphis noxia<br> <strong>Macrosiphum albifrons</strong><br> Metopolophium dirhodum<br> Myzus cerasi </em>(updated annotation)<br> <em>Myzus ligustri<br> Myzus lythri<br> Myzus varians<br> Pentalonia nigronervosa </em>(updated annotation)<br> <em><strong>Phorodon humuli</strong><br> <strong>Rhopalosiphum padi<br> Sitobion avenae<br> Sitobion miscanthi</strong></em></p>
Data from: Radial stem growth of the clonal shrub Alnus alnobetula at treeline is constrained by summer temperature and winter desiccation and differs in carbon allocation strategy compared to co-occurring Pinus cembra
<p><strong>Data are documented in the following article:</strong></p> <p>Oberhuber W., G Wieser, F. Bernich, A. Gruber (2022) Radial stem growth of the clonal shrub <em>Alnus alnobetula</em> at treeline is constrained by summer temperature and winter desiccation and differs in carbon allocation strategy compared to co-occurring <em>Pinus cembra</em>. Forests 2022, 13, 440. doi: 10.3390/f13030440.</p> <p> </p> <p><strong>Summary:</strong></p> <p>Global change is affecting species areal distribution in many regions. A better understanding of how land-use change and climate warming affects shrub growth is essential for improved predictions of forest dynamics at the alpine treeline. Evaluation of radial stem growth of the clonal shrub <em>Alnus alnobetula</em> (= <em>Alnus viridis</em>) and the co-occurring tree species Swiss stone pine (<em>Pinus cembra</em>) within an alpine treeline ecotone revealed that mean ring width of nitrogen fixing <em>A. alnobetula</em> was about four times lower compared to <em>P. cembra</em>. Our findings are based on ring width data from <em>A. alnobetula</em> and <em>P. cembra</em> stems sampled at the alpine treeline ecotone on Mt. Patscherkofel (47°12’N, 11°27’E, Central European Alps, Austria, elevation range 2050 to 2190 m asl). Ring width time series include 86 radii from 51 stems of <em>A. alnobetula</em> (stems had mean age of 18±7 yrs) and 24 radii from 16 stems of <em>P. cembra </em>(18±4 yrs). We explain our findings by different carbon allocation strategies, i.e., preference of “vertical” stem growth in late successional <em>P. cembra</em> vs. favoring “horizontal” spread in the pioneer shrub<em> A. alnobetula.</em> By favouring clonal propagation over individual stem growth <em>A. alnobetula</em> is able to quickly spread at the alpine treeline ecotone.</p>

Data from: BioEncoder: a metric learning toolkit for comparative organismal biology
<p><strong>BioEncoder: a metric learning toolkit for comparative organismal biology</strong></p> <p><strong>Abstract </strong>- In the realm of biological image analysis, deep learning (DL) has become a core toolkit, e.g., for segmentation and classification. However, conventional DL methods are challenged by large biodiversity datasets characterized by unbalanced classes and hard-to-distinguish phenotypic differences between them. Here we present BioEncoder, a user-friendly toolkit for metric learning, which overcomes these challenges by focussing on learning relationships between individual data points rather than on the separability of classes. BioEncoder is released as a Python package, created for ease of use and flexibility across diverse datasets. It features taxon-agnostic data loaders, custom augmentation options, and simple hyperparameter adjustments through text-based configuration files. The toolkit's significance lies in its potential to unlock new research avenues in biological image analysis while democratizing access to advanced deep metric learning techniques. BioEncoder focuses on the urgent need for toolkits bridging the gap between complex DL pipelines and practical applications in biological research.</p> <p><strong>Dataset </strong>- This data repository includes two things: a snapshot of the BioEncoder package (BioEncoder-main.zip, version 1.0.0, downloaded from https://github.com/agporto/BioEncoder on 2024-07-19 at 17:20), and the damselfly dataset used for the case study presented in the paper (bioencoder_data.zip). The dataset archive also encompasses the configuration files and the final model checkpoints from the case study, as well as a script to reproduce the results and figures presented in the paper.</p> <p><strong>How to use - </strong>Get started by consulting the <a href="https://github.com/agporto/BioEncoder?tab=readme-ov-file#quickstart">GithHub repository</a> for information on how to install BioEncoder, then download the <a href="../records/10909614/files/BioEncoder-data.zip?download=1&preview=1">data archive</a> and run the script. Some parts of the script can be executed using the model checkpoints, for orther parts the training rountine needs to be run. </p>

Comparing the integration of bone cells on an even and a nano structured surface
<p>Bone cells develop better on a nano structured surface.</p> <p>Successful cellular integration is extremely important to the long-term viability of dental implants. The sooner cells can attach and surround the implant, the faster the patient recovers, and the lower the incidence of infection and site contamination. The specific biological response of the surrounding tissues depends enormously on the surface characteristics of the particular biomaterial. Moreover mouth infections are currently regarded as the main reason why dental implants fail. Therefore, antibacterial properties are another requirement for preventing potential bacterial infection.</p> <p>The multi-beam optical module developed within LASER4SURF, will be able to obtain functionalized metallic surfaces with textures around 1μm or less, enabling the required tolerances to reach the best cell adhesion and antibacterial properties. Thus, it will lead to extended implant life, reduced rejection and improved overall quality of life for patients.</p>

ACTIV-ES: a comparable Spanish corpus comprised of film dialogue from Argentine, Mexican and Spanish productions
<p><strong>DESCRIPTION</strong>: ACTIV-ES is a comparable Spanish corpus comprised of film dialogue from Argentine, Mexican and Spanish productions. Titles for each of these three countries were seeded from the Internet Movie Database, subtitle data for the hearing impaired was provided by Opensubtitles.org and was post-processed to correct/remove subtitle, OCR and diacritic artifacts and annotated for part-of-speech.</p> <p>The data is available in two main formats: 1) running text for each document and 2) 1:5 gram aggregate files. Each format includes a plain text and part-of-speech annotated version. Document names reflect the language code, country, year, title, type, genre (first genre listed in the IMDb), and IMDb ID.</p> <p>For more information about the development and evaluation of these resources and to cite this work refer to:</p> <p>Francom, J., Hulden, M. and Ussishkin, A..

Comparative Dataset on Migration
<p>The purpose of this dataset is to provide a systematic set of standardised contextual (economic, socio-political, cultural and legal) indicators in order to identify and measure on a comparative basis those contextual factors that have an (beneficial or inhibiting) impact on European, but not exclusively, responses to mass migration. Attention has been paid to existing socio-economic conditions and to national policies related to immigrants and asylum seekers. In this respect, the dataset comprises a set of both macro-level indicators measuring the socio-economic, political and institutional context of migration and cultural – or individual-level – indicators addressing ordinary citizens’ subjective attitudes, behaviours and perceptions about migration related-phenomena (e.g. perceived discrimination on ethnic grounds; immigration being bad or good for a country's economy; a country's cultural life being undermined or enriched by immigration).</p>

<p>Data used in paper "A comparative study of calibration methods for low-cost ozone sensors in IoT platforms", submitted for publication. The data consists of: (i) raw data from three nodes with four MICS 2614 metal-oxide ozone sensors deployed in Spain, summer 2017, and (ii) raw data of five alphasense OX-B431 and NO2-B43F electro-chemical sensors, four deployed in Italy and one in Austria, summers 2017 and 2018. Moreover, we have added the calibrated data using four machine learning methods: Multiple Linear Regression (MLR), K-Nearest Neighbors (KNN), Random Forest (RF) and Support Vector Regression (SVR).</p>
Comparatives, Quantifiers, Proportions
<p>The present work investigates whether different quantification mechanisms (set comparison, vague quantification, and proportional estimation) can be jointly learned from visual scenes by a multi-task computational model. The motivation is that, in humans, these processes underlie the same cognitive, non-symbolic ability, which allows an automatic estimation and comparison of set magnitudes. We show that when information about lower complexity tasks is available, the higher-level proportional task becomes more accurate than when performed in isolation. Moreover, the multi-task model is able to generalize to unseen combinations of target/non-target objects. Consistently with behavioral evidence showing the interference of absolute number in the proportional task, the multi-task model no longer works when asked to provide the number of target objects in the scene.</p>
