Fig. 6 in Reproductive biology, embryonic development and matrotrophy in the phylactolaemate bryozoan Plumatella casmiana
Fig. 6 Late embryo of Plumatella casmiana, longitudinal section. a Overview of the large thin-walled embryo sac next to the ovary with mature oocytes. The embryo oc- cupies almost the entire cavity of the brood sac and has started to form buds in its distal region. b Ectodermal cells (asterisks) of the posterior pole of the embryo are in direct contact to the maternal ectodermal cells of the embryo sac. c Early bud formation. Ectodermal cells proliferate (arrows) and ingress, while the adjoining mesoderm thickens and surrounds the ectodermal ingression. d Establishment of contact between the embryonic ectoderm (asterisk) and the mesodermal layer of the embryo sac. The bor- der between the ectodermal and mesodermal layer of the embryo sac is shown by a dashed line in b and c. Abbreviations: ebs embryo sac, eme embryonic ectoderm, emm embryonic mesoderm, mec maternal ectoderm cells
Fig. 3 in Reproductive biology, embryonic development and matrotrophy in the phylactolaemate bryozoan Plumatella casmiana
Fig. 3 Ovary and embryo sac formation in Plumatella sp. a Early ovary in the body wall. Embryo sac formation occurs next to the ovary with its initial stage detectable by proliferation of the epidermal layer. b More progressed stage than in 'a' with the ovary and embryo sac protruding more into the body cavity of the zooid. c The oocyte number increases, and the largest and most mature oocytes are situated at the free end of the ovary towards the coelomic cavity. d Embryo sac with enclosed early embryo in the proximal part.

Molecular Biology Open Access Pubmed Word and Sentence Representations
<p><strong>Natural Language Embeddings about Molecular Biology</strong></p> <p>This dataset is concerned with developing a tailored training data set for word and sentence embedding based on biomedical text that has some component associated with molecular work (as opposed to the other range of work indexed in PubMed like non molecular clinical work, studies of human behavior, etc). </p> <p><strong>Raw Data</strong></p> <p>In order to develop natural language embeddings (for words and sentences), we queried PMC and MEDLINE for molecular papers only by using high-level MeSH terms to restrict interest to papers with a molecular focus. We used the following MeSH terms:</p> <ul> <li>Cells [A11]</li> <li>Multiprotein Complexes [D05.500]</li> <li>Protein Aggregates [D05.875]</li> <li>Hormones [D06]</li> <li>Enzymes and Coenzymes [D08]</li> <li>Carbohydrates [D08]</li> <li>Lipids [D10]</li> <li>Amino Acids, Peptides and Proteins [D12]</li> <li>Nucleic Acids, Nucleotides and Nucleosides [D13]</li> <li>Biological Factors [D23]</li> <li>Pharmaceutical Preparations [D26]</li> <li>Metabolism [G03]</li> <li>Genetic Phenomena [G06]</li> </ul> <p>Queries for these terms use the following string:</p> <blockquote> <p>"cells"[MeSH Terms] OR "Multiprotein Complexes"[mh] OR "Protein Aggregates"[mh] OR "Hormones, Hormone Substitutes, and Hormone Antagonists"[mh] OR "Enzymes and Coenzymes"[mh] OR "Carbohydrates"[mh] OR "Lipids"[mh] OR "Amino Acids, Peptides, and Proteins"[mh] OR "Nucleic Acids, Nucleotides, and Nucleosides"[mh] OR "Biological Factors"[mh] OR "Pharmaceutical Preparations"[mh] OR "Metabolism"[mh] OR "Cell Physiological Phenomena"[mh] OR "Genetic Phenomena"[mh]</p> </blockquote> <p>PubMed returns 11,447,521 abstracts. PMC returns, 1,720,266 documents, 509,722 of these are open access. We downloaded, parsed and concatenated 403,825 PMC open access documents into a single file `molecular_oa_pmc.tsv`. This is a 33GB TSV file with the following columns:</p> <ul> <li>File:Paragraph - a unique identifier for each paragraph</li> <li>SentenceId - the local number of the sentence in the document</li> <li>Sentence Text - tokenized text of the sentence (based on <a href="https://github.com/ClearTK/cleartk/blob/master/cleartk-token/src/main/java/org/cleartk/token/tokenizer/TokenAnnotator.java">ClearTk's TokenAnnotator.java</a>)</li> <li>Codes - <code>exLink</code> for the presence of a citation, <code>inLink</code> for the presence of link to a Figure</li> <li>Figures - Figure codes</li> <li>Headings - High level section of the paper</li> <li>Offset_Begin - offset of the start of the sentence within the paper</li> <li>Offset_End - offset of the start of the sentence within the paper</li> </ul> <p>We repeated the same process for PubMed abstracts to generate a 3.6G file (`molecular_oa_medline.tsv`) with three columns:</p> <ol> <li>Pubmed ID</li> <li>A Boolean value indicating whether the article is a review</li> <li>Text</li> </ol> <p>We concatenated the text columns of these two files into a single 30GB file (`molecular_oa.txt`) where each line is a single sentence and the text is fully tokenized. </p> <p>These three files are archived in `molecular_oa_raw_text.tar.gz`.</p> <p><strong>Fasttext Embedding</strong></p> <p>We trained a fasttext model on the raw training data (https://fasttext.cc/) using the standard `skipgram` parameter.

The impact of biological bedforms on near-bed and subsurface flow: a laboratory validated numerical study of flow in the vicinity of pits and mounds
<p>The data were used in the paper "The impact of biological bedforms on near-bed and subsurface flow: a laboratory validated numerical study of flow in the vicinity of pits and mounds" which was submitted to "Journal of Geophysical Research-Earth Surface". In this paper, a novel, unified water-sediment three-dimensional model is developed to investigate the impact of simulated biogenic bedforms. The impact of biogenic bedforms on near-bed turbulence and sediment entrainment is discussed in gravelly substrates. Biogenic bedform morphology has an important role in determining the spatial extent of up- and down-welling flow.</p>
