TRADE4SD Deliverable 2.3: Database and infographics on standards rapprochement: STCs and bilateral measure of distance on pesticides and antibiotics
<p><span>One of the objectives of the Horizon2020 project “TRADE4SD” is to offer policy recommendations for improving trade policies at the national, European, and global levels, including reforms to the WTO, and to enhance policy alignment. To achieve this goal, it is essential to address the impact of NTMs, which, despite their increasing use, remain largely underexplored in terms of the effects on international trade. This limited understanding is due to the complexity of NTMs and their effects are difficult to generalise. Several critical areas related to NTMs and their implications for international trade require further investigation, which “TRADE4SD” seeks to address. This work explores how NTMs affect market access for developing countries, as these nations may face various challenges, such as limited capabilities, technological gaps, weaker infrastructures and institutions, and asymmetric information. More specifically, “TRADE4SD” aims to identify best practices for improving the management of SPS, which are essential for enhancing the competitiveness of agricultural and food exports. Strengthening SPS capacity is also vital for boosting productivity in the agricultural and food processing industries, contributing to agricultural and rural development, and helping to alleviate poverty. </span></p> <p><span>This deliverable consists of two main sections: one addressing Maximum Residue Levels (MRLs) for pesticides and antibiotics and the other focusing on Specific Trade Concerns (STCs). </span></p> <p><span>In the first section, we analysed the regulations and then acquired and processed the data to create the databases, which we later used to develop the indices and infographics (for both pesticides and antibiotics).</span></p> <p><span>In the STCs section, we analysed WTO documentation on all open disputes and verified their status. During our analysis, we identified the relationships between STCs and the Sustainable Development Goals (SDGs). Finally, we developed the infographics.</span></p>
Standard Model corrections to Fermi decays in NCSM
<p>Recent analysis of Fermi decays by C.Y. Seng and M. Gorshteyn and the corresponding $V_{ud}$ determination have revealed a degree of tension with Cabibbo-Kobayashi-Maskawa (CKM) matrix unitarity, confirmation of which would indicate several potential deficiencies within the Standard Model (SM) weak sector. Extraction of $V_{ud}$ requires electroweak radiative corrections (EWRC) from theory to be applied to experimentally obtained $ft$-values. Novel calculations of corrections sensitive to hadronic structure, i.e., the $\gamma W$-box, are at the heart of the recent tension. Moreover, to further improve on the extraction of $V_{ud}$, a modern and consistent treatment of the two nuclear structure dependent corrections is critical. These corrections are (i) $\delta_C$, the isospin symmetry breaking correction (ii) and $\delta_{NS}$, the EWRC representing evaluation of the $\gamma W$-box on a nucleus. Preliminary estimations of $\delta_{NS}$ have been made in the aforementioned analysis, however, the approach cannot include effects from low-lying nuclear states which require a true many-body treatment. Via collaboration with C.Y. Seng and M. Gorshteyn and use of the Lanczos subspace method, these corrections can be computed in ab initio nuclear theory for the first time. We apply the no-core shell model (NCSM), a nonrelativistic quantum many-body theory for describing low-lying bound states of $s$- and $p$-shell nuclei starting solely from nuclear interactions. We will present preliminary results for $\delta_{NS}$ and $\delta_{C}$ determined in the NCSM for the $^{10}\text{C} \rightarrow {}^{10}\text{B}$ beta transition, with the eventual goal of extending the calculations to $^{14}\text{O} \rightarrow {}^{14}\text{N}$ and $^{18}\text{Ne} \rightarrow {}^{18}\text{F}$.</p>

A standardized assessment of forest mammal communities reveals consistent functional composition and vulnerability across the tropics
<p class="MsoPlainText">Understanding global diversity patterns has benefitted from a focus on functional traits and how they relate to variation in environmental conditions among assemblages. Distant communities in similar environments often share characteristics, and for tropical forest mammals, this functional trait convergence has been demonstrated at coarse scales (110-200 km resolution), but less is known about how these patterns manifest at fine scales, where local processes (e.g., habitat features and anthropogenic activities) and biotic interactions occur. Here, we used standardized camera trapping data and a novel analytical method that accounts for imperfect detection to assess how the functional composition of terrestrial mammal communities for two traits – trophic guild and body mass – varies across 16 protected areas in tropical forests and three continents, in relation to the extent of protected habitat and anthropogenic pressures. We found that despite their taxonomic differences, communities generally have a consistent trophic guild composition, and respond similarly to these factors. Insectivores were found to be sensitive to the size of protected habitat and surrounding human population density. Body mass distribution varied little among communities both in terms of central tendency and spread, and interestingly, community average body mass declined with proximity to human settlements. Results indicate predicted trait convergence among assemblages at the coarse scale reflects consistent functional composition among communities at the local scale, suggesting that broadly similar habitats and selective pressures shaped communities with similar trophic strategies and responses to drivers of change. These similarities provide a foundation for assessing assemblages under anthropogenic threats and sharing conservation measures.Understanding global diversity patterns has benefitted from a focus on functional traits and how they relate to variation in environmental conditions among assemblages.

NLM-Gene, a richly annotated gold standard dataset for gene entities that addresses ambiguity and multi-species gene recognition
<p>The automatic recognition of gene names and their corresponding database identifiers in biomedical text is an important first step for many downstream text-mining applications. The NLM-Gene corpus is a high-quality manually annotated corpus for genes, covering ambiguous gene names, with an average of 29 gene mentions (10 unique identifiers) per article, and a broader representation of different species (including <i>Homo sapiens, Mus musculus, Rattus norvegicus, Drosophila melanogaster, Arabidopsis thaliana, Danio rerio,</i> etc.) when compared to previous gene annotation corpora. NLM-Gene consists of 550 PubMed articles from 156 biomedical journals, doubly annotated by six experienced NLM indexers, randomly paired for each article to control for bias. The annotators worked in three annotation rounds until they reached a complete agreement. Using the new resource, we developed a new gene finding algorithm based on deep learning which improved both on precision and recall from existing tools. The NLM-Gene annotated corpus is freely available at Dryad and at <a href="https://www.ncbi.nlm.nih.gov/research/bionlp/">https://www.ncbi.nlm.nih.gov/research/bionlp/</a>. The gene finding results of applying this tool to the entire PubMed/PMC are freely accessible through our web-based tool PubTator.</p>

Data for: Are immigrants outbred and unrelated? Testing standard assumptions in a wild metapopulation
<p><span>Immigration into small recipient populations is expected to alleviate inbreeding and increase genetic variation, and hence facilitate population persistence through genetic and/or evolutionary rescue. Such expectations depend on three standard assumptions: that immigrants are outbred, unrelated to existing natives at arrival, and unrelated to each other. These assumptions are rarely explicitly verified, including in key field systems in evolutionary ecology. Yet, they could be violated due to non-random or repeated immigration from adjacent small populations. We combined molecular genetic marker data for 150-160 microsatellite loci with comprehensive pedigree data to test the three assumptions for a song sparrow (<i>Melospiza melodia)</i> population that is a model system for quantifying effects of inbreeding and immigration in the wild. Immigrants were less homozygous than existing natives on average, with mean homozygosity that closely resembled outbred natives. Immigrants can therefore be considered outbred on the focal population scale. Comparisons of homozygosity of real or hypothetical offspring of immigrant-native, native-native and immigrant-immigrant pairings implied that immigrants were typically unrelated to existing natives and to each other. Indeed, immigrants' offspring would be even less homozygous than outbred individuals on the focal population scale. The three standard assumptions of population genetic and evolutionary theory were consequently largely validated. Yet, our analyses revealed some deviations that should be accounted for in future analyses of heterosis and inbreeding depression, implying that the three assumptions should be verified in other systems to probe patterns of non-random or repeated dispersal and facilitate precise and unbiased estimation of key evolutionary parameters.</span></p>
WATER: AN ONLINE TOOLKIT TO SUPPORT THE RESEARCH FOR STANDARDS
<p>Within <a href="https://www.eu-project-o.eu/">Project Ô</a>, the European Commission-funded Horizon 2020 project, <a href="https://www.uni.com/">UNI</a> - Italian Standardization Body has realized a <strong>first version of an online <a href="https://www.eu-project-o.eu/standardization-toolkit/">Standardization Toolkit</a></strong><a href="https://www.eu-project-o.eu/standardization-toolkit/"> </a>to support the research over a dataset of more than 100 standardization documents in the field of water and its management.</p> <p>The Standardization Toolkit, finalized in May 2021, is based on the vision of Project Ô.</p> <p>Specifically, the toolkit consists of an online tool, which let you select standards choosing among several filters. For example, it is possible to select standards starting from technical committees at national (UNI), European (CEN) and international (ISO) level. In addition, it is possible to make a deeper search by selecting standards according to specific areas and/or keywords.</p> <p>The list of standards will be the result of what emerges by searching in a panel of more than 100 different standardization documents identified within the activity of mapping that was carried out for Project Ô. The standards are related to the theme of water, its reuse also in a circular economy perspective, and to the environmental management.</p> <p>Standardization is a key tool for technology transfer, bridging the gap between research and the international market.</p> <p>Standards codify innovation through a shared language understood by companies, researchers, stakeholders and citizens worldwide, based on the principles of openness and transparency. The co-creation process of standardization supports open innovation and cross-sectoral innovation.</p> <p>Standards ensure comparability, compatibility and interoperability, building trust with customers and suppliers, promoting sustainability in terms of processes, products and business.</p> <p>On Zenodo it has been uploaded the dataset behind this toolkit. </p> <p> </p>
Data from: Comparisons of quantitative approaches for assessing microglial morphology reveal inconsistencies, ecological fallacy, and a need for standardization
<p>Microglia morphology is used as a measure of neuroinflammation and pathology, but different methods to quantify microglia morphology are frequently employed across neuroscience. For reliable inference, it is critical that microglial morphology is accurately quantified and that results can be easily interpreted and compared across studies. We applied five of the most commonly used ImageJ-based methods for quantifying the microglial morphological response to a stimulus to identical photomicrographs and isolated microglial cells, which allowed for direct comparisons of the specificity and reliability of each method.</p>
