Botryococcus braunii reduces algal grazing losses to Daphnia and Poterioochromonas through both chemical and physical interference

<p>The data and code provided here is used to analyze and visualize all data associated with the manuscript "<em>Botryococcus braunii</em> reduces algal grazing losses to <em>Daphnia</em><br>and <em>Poterioochromonas </em>through both chemical and physical interference" in the Journal of Applied Phycology under the DOI: 10.1007/s10811-024-03330-x</p> <p>Data should be analyzed in R or R studio. The code in the .Rmd file should execute automatically with no modifications by the user as long as the two csv files are placed in the same working directory that R is set to. The R project (.Rproj) file may also be opened directly to create an R project that is automatically set to the correct directory. Metadata explaining the contents of two data files is provided in the README.csv file.</p> <p>ABSTRACT: Crop protection from algal grazers is a key area of concern, as grazing zooplankton and flagellates can decimate microalgae crops and impede economic viability of cultivation for biofuels and bioproducts. Inhibition of grazing by chemical and physical interference is one promising solution; however, there have been few empirical tests of this approach that use defense traits innate to algal crop species. <em>Botryococcus braunii </em>is of particular interest because a) it excretes high levels of hydrocarbons and exopolysaccharides and b) forms colonies and possesses chemical defenses. Here we conduct a controlled laboratory experiment to test whether <em>B. braunii</em> can mitigate losses to grazing by two distinct grazers, <em>Daphnia magna</em> and <em>Poterioochromonas malhamensis</em>, due to both chemical inhibition and physical interference linked to large/inedible colonies. We show that chemical and physical defenses interactively reduce the total effect of grazing, thus significantly increasing the biomass and growth rates of cultures of <em>B. braunii</em> and <em>Nannochloropsis limnetica</em> when either grazer is present. We also find that <em>B. braunii </em>medium enhances the growth of <em>N. limnetica</em>. Our study demonstrates how community engineering can identify synergies arising from algal co-cultivation (e.g., by using industrially relevant strains for crop protection). While our lab study serves as a proof-of-concept, future research should test this strategy at pilot scale; if successful, such ecological discoveries may help to reduce the costs of large-scale deployment of algal cultivation for sustainable foods, fuels, bioproducts (e.g., bioplastics), and carbon capture.</p>

Part 2 of real-time testing data for: "Identifying data sources and physical strategies used by neural networks to predict TC rapid intensification"

<p>Each file in the dataset contains machine-learning-ready data for one unique tropical cyclone (TC) from the real-time testing dataset. &nbsp;"Machine-learning-ready" means that all data-processing methods described in the journal paper have already been applied. &nbsp;This includes cropping satellite images to make them TC-centered; rotating satellite images to align them with TC motion (TC motion is always towards the +x-direction, or in the direction of increasing column number); flipping satellite images in the southern hemisphere upside-down; and normalizing data via the two-step procedure.</p> <p>The file name gives you the unique identifier of the TC -- e.g., "learning_examples_2010AL01.nc.gz" contains data for storm 2010AL01, or the first North Atlantic storm of the 2010 season. &nbsp;Each file can be read with the method `example_io.read_file` in the ml4tc Python library (https://zenodo.org/doi/10.5281/zenodo.10268620). &nbsp;However, since `example_io.read_file` is a lightweight wrapper for `xarray.open_dataset`, you can equivalently just use `xarray.open_dataset`. &nbsp;Variables in the table are listed below (the same printout produced by `print(xarray_table)`):</p> <p>Dimensions: &nbsp;

How physical activity opportunities seized by adolescents differ between Europe and the Pacific Islands: the example of France and New Caledonia

<p><strong><span>Background</span></strong></p> <p><span>France (FR) and New Caledonia (NC) are both French territories, one in Western Europe, the other as part of the Pacific <a name="_Hlk172132305"></a>Island Countries and Territories (PICTs). Despite schooling in similar educational systems, FR and NC adolescents develop distinct relationships with physical activity, which is influenced by the geographical-cultural and symbolic structures of their respective societies. This study explored the distribution of physical activity according to geographical culture and opportunity-temporal dimensions.</span></p> <p><strong><span>Methods</span></strong></p> <p><span>Participants were randomly selected, with individual (boys vs. girls), spatial (rural vs. urban), and geographical (FR vs. NC) stratifications. Accelerometers and daily logbooks were used to measure the physical activity intensity and opportunities during the week.</span></p> <p><strong><span>Results</span></strong></p> <p><span>A total of 156 participants were included in this study. A significant effect was found in moderate to vigorous physical activity (MVPA) intensity with the geographical-cultural dimension; participants living in FR were more likely to engage in MVPA, especially in five opportunities: school, supervised leisure, home, school breaks, and transport. For both FR and NC adolescents, physical education lessons had the highest MVPA.</span></p> <p><strong><span>Conclusion</span></strong></p> <p><span>This study showed that MVPA differed in the same national educational system according to geographical culture. Physical education lessons could catch the challenge of an &ldquo;opportunity education&rdquo; (opportunities are defined as temporal invitations to engage in PA) by opening the door to two particular opportunities: supervised leisure and active transport.</span></p>

Dataset for the study: Closed-boundary reflections of shallow water waves as an open challenge for physics-informed neural networks

<p>This dataset supports a study on using Physics-Informed Neural Networks (PINNs) to solve the 1D-Shallow Water Equations. It focuses on closed boundary reflection test cases, which are crucial for accurately modeling geophysical fluid dynamics in coastal regions, particularly for storm surge and flood modeling. Properly representing reflections is also essential for accurately modeling related phenomena, such as Kelvin waves and amphidromic systems, which influence coastal water levels during such events. The individual sub-datasets in NetCDF format provide the results used for one figure each. The data arrays within the datasets are named with reference to the figures for ease of comparison.&nbsp;<br><br>Cite as: Demir, K.T.; Logemann, K.; Greenberg, D.S.

Physical dataset for OneFlow data/MC corrections

<p>This dataset contains two files (data and MC) with one million entries each. The synthetic samples resemble typical distributions in high-energy physics and emulate a mismodelling of Monte-Carlo simulated distributions that do not fully agree with data. The samples have one index and seven features (pT, eta, noise, v1A, v2A, v1B, v2B). The dataset features non-trivial correlations and conditioning of the latter four v-features on the first three variables pT, eta, and noise. The v1A and v2A features are Gaussian-like, whereas the v1B and v2B features are discontinuous.</p> <p>This dataset is well suited to explore correction methods, both morphing and reweighting, in a challenging setup.</p> <p>This dataset was used in the publication <a href="https://link.springer.com/article/10.1007/s41781-024-00125-0">One Flow to Correct Them all: Improving Simulations in High-Energy Physics with a Single Normalising Flow and a Switch</a> to demonstrate the suitability of a single normalising flow to morph the MC distribution into the data distribution.

Permeable pavement hydraulic performance and clogging experiments using a full-scale urban drainage physical model

<p>This dataset contains the results from 15 tests conducted used a physical model in the Hydraulic Laboratory of the Centre for Technological Innovation in Construction and Civil Engineering (CITEEC) at the University of A Coru&ntilde;a (Spain) as part of the POREDRAIN project.</p> <p><br>The objective of the tests is to analyse the hydraulic performance of a porous asphalt layer of the PA-16 type and the impact of clogging on the hydrological behaviour and water quality of the effluent. The porous asphalt was used to retrofit an impervious concrete surface of a 36 m&sup2; full-scale street section physical model, which consist of a rainfall simulator placed over the street surface. The behaviour of the porous asphalt layer was assessed by adding surface sediment loads between simulated rainfall events. Stormwater flow discharges were collected from two gully pots and an outlet lateral channel.&nbsp;</p>

Training word vectors on text from The Physics Teacher using Word2Vec

<p>This notebook and dataset allows one to play around with word vectors trained on text from articles in the journal <a href="https://pubs.aip.org/aapt/pte">The Physics Teacher</a> published between 1963 (the start of publication) and 2020, around 15000 articles in total.</p> <p>The primary datafile, "TPT_word2vec_words_bigrams_V1.pkl", is a list of cleaned text from these articles. It contains a list, within which each paper is a sub-list. Each sentence in that paper is yet another sub-list which contains the words in that sentence in order. However, in the data cleaning process we have removed &ldquo;stop words&rdquo; (like if, and, but, etc.), punctuation, symbols, and numbers, as well as lowercased all words and combined words that frequently go together into one (like &ldquo;high&rdquo; and "school&rdquo; to &ldquo;high_school&rdquo;). Here is an example of 3 sentences taken from a random paper:&nbsp;<br>&nbsp;<br>[['magnet', 'spin', &nbsp;'tape', &nbsp;'magnetize', &nbsp;'strongly', &nbsp;'time', &nbsp;'pole', &nbsp;'approach'],<br>['magnet', &nbsp;'place', &nbsp;'center', &nbsp;'counterweight', &nbsp;'period', &nbsp;'magnetize', &nbsp;'pulse', &nbsp;'twice', &nbsp;'long'],<br>['trial', 'tape', 'examine', 'sprinkle_iron', 'filing', 'length'], ... ]</p> <p>In the notebook, we create a set of word vectors from these sentences using the Word2Vec technique, first published by Mikolov et al. (2013):</p> <p>Mikolov, T., Chen, K., Corrado, G., &amp; Dean, J. (2013). Efficient Estimation of Word Representations in Vector Space (No. arXiv:1301.3781). arXiv. https://doi.org/10.48550/arXiv.1301.3781</p> <p>The notebook includes code for both loading in word vectors from a trained model (also included, "TPT_word2vec.model") and creating the same model from the TPT text dataset. Note that word vectors are randomly initialized, so we include a random seed to make this training replicable. Changing the seed will alter some of the results (although the changes seem fairly minor).</p> <p>With a trained model, we demonstrate some applications of word vectors: adding and subtracting meanings <br>(for example "experiment" - "uncertainty" = "demonstration") and visualizing low-dimensional representations of word vectors.</p> <p>In order to install the required packages, you can use the requirements.txt file. &nbsp;If using pip, run "pip install requirements.txt". Or, if using Anaconda (recommended), you can use "conda install --file requirements.txt". You will also need the software to run jupyter notebooks, which can be installed with Anaconda or pip.</p>
