Robust step detection from different waist-worn sensor positions – implications for clinical studies

<p>The dataset contains tri-axial acceleration and gyroscope data (100 Hz sampling) from walks from 19&nbsp;healthy volunteers, each walking up to three times a parcours of 20 meters with self-selected speed, slow speed or with five soft turns at self-selected&nbsp;speed. Each participant wore 11 time-synchronized sensors during these tests: left/right foot, 5&nbsp;around&nbsp;waist, non-dominant wrist and upper arm and collar&nbsp;and&nbsp;pocket. In addition to the sensor recordings each 20 meter walk was timed with a stop-watch.&nbsp;&nbsp;</p> <p>Also see:&nbsp;<a href="https://doi.org/10.1159/000511611">https://doi.org/10.1159/000511611</a></p>

Accounting for environmental variation in co‐occurrence modelling reveals the importance of positive interactions in root‐associated fungal communities

<p>Understanding the role of interspecific interactions in shaping ecological communities is one of the central goals in community ecology. In fungal communities, measuring interspecific interactions directly is challenging because these communities are composed of large numbers of species, many of which are unculturable. An indirect way of assessing the role of interspecific interactions in determining community structure is to identify the species co-occurrences that are not constrained by the environmental conditions. In this study, we investigated co-occurrences among root-associated fungi, asking whether fungi co-occur more or less strongly than expected based on the environmental conditions and the host plant species examined. For this purpose, we generated molecular data on root-associated fungi of five plant species evenly sampled along an elevational gradient at a high Arctic site. We analysed the data using a joint species distribution modelling approach that allowed us to identify those co-occurrences that could be explained by the environmental conditions and the host plant species, as well as those co-occurrences that remained unexplained and thus more likely reflect interactive associations. Our results indicate that positive interactions play an important role in shaping microbial communities in arctic plant roots. In particular, we found that mycorrhizal fungi are especially prone to positively co-occur with other fungal species. Our results bring new understanding to the structure of arctic interaction networks by suggesting that interactions among root-associated fungi are predominantly positive.</p>

High-quality large curated dataset of protein sequences (1.83 million) and their corresponding Position Specific Scoring Matrices

<p>As part of his&nbsp;master thesis at the Rostlab, which is located at the Technical University of Munich (TUM),&nbsp;Mr. Issar Arab&nbsp;developed&nbsp;the first language model that encodes evolutionary information of proteins explicitly. The pre-training involved the creation of a novel high-quality dataset of protein sequences (around 1.83&nbsp;million proteins, or ~0.8 Billion amino acids) with their corresponding Position Specific Scoring Matrices (PSSMs).&nbsp; Those matrices reflect the relative frequency of each amino acid at each position in a protein and is derived from evolutionarily related proteins.</p> <p>Mr. Arab makes this work publicly available to help other researchers speed up their work to leverage AI to learn the representation of protein evolutionary information more explicitly. The set of sequences was derived by extracting all PSSMs from the&nbsp;<a href="https://predictprotein.org/">PredictProtein</a>&nbsp;(PP) cache, which&nbsp;were also part o the UniProt&nbsp;Reference Cluster with 50% sequence identity (uniref50 2019_12). The overlap between PP and uniref50 was further filtered to only include high-quality samples, e.g. only multiple sequence alignments with a certain number of aligned sequences were considered. The processing led to&nbsp;a training set of 1.83 Million sequences, a validation set of 879 instances, and a test set of 879 entries.&nbsp;The training data of proteins is reduced to 40% sequence identity, with respect to the validation/test sets, and contains sequences ranging between 18 and 9858 residues in length.</p> <p>Refer to the Jupyter notebook for a detailed description of the files'&nbsp;structure and a Python code snippet to correctly manipulate&nbsp;this data.</p> <p>To access the full original&nbsp;work, please visit the following link:&nbsp; <a href="https://mediatum.ub.tum.de/node?id=1579236">Manuscript</a>&nbsp;<br><br><strong>Note:</strong> The dataset was recently used to fine tune a protein sequence language model (<a href="https://github.com/issararab/PEvoLM">PEvoLM</a>).
