title: A catalog of genes, genomes and species of the dog (Canis lupus familiaris) intestinal microbiota

description: Data sourcesThis dataset was constructed using metagenomic sequencing data from the bioproject PRJEB20308 from Coelho et al. 2018 (129 samples)
Metagenomic assemblyFirst, sequencing adapters removal and read trimming was performed with fastp. Reads mapped on the host genome (ROS_Cfam_1.0 GCF_014441545.1) with bowtie2 were removed with samtools. Finally, Metagenomic assembly was performed with metaSPAdes. Contigs of less than 1500 bp were removed.
MAGs recoveryMAGs were generated with COMEBin (multi-coverage mode) and MAGs quality was assessed with CheckM2. MAGs with completeness < 70% or contamination > 5% or N50 < 5Kb were discarded. Pairwise Average Nucleotide Identity (ANI) was computed for all recovered MAGs with fastANI and dereplication at species level (ANI cutoff = 95%).
Non-redundant gene catalogGenes were predicted on all contigs from metagenomic assemblies with Prodigal (parameters : -m -p meta). Genes were pooled and clustered with cd-hit-est (parameters -c 0.95 -aS 0.90 -G 0 -d 0 -M 0 -T 0) by choosing those from the longest contigs as representatives.
MSPs recoveryReads were aligned against the non-redundant gene catalog with the Meteor software suite to produce a raw gene abundance table (1,0M genes quantified in 129 samples). Then, co-abundant genes were binned in 234 Metagenomic Species Pan-genomes (MSPs, i.e. gene clusters that likely belong to the same microbial species) using MSPminer.
MAGs and MSPs taxonomic annotationDereplicated MAGs were annotated with GTDB-Tk based on GTDB r220. Then, MAGs taxonomic annotation was propagated to the corresponding MSPs.
Construction of the phylogenetic tree39 universal phylogenetic markers genes were extracted from the dereplicated MAGs with fetchMGs. Then, the markers were separately aligned with MUSCLE. The 40 alignments were merged and trimmed with trimAl (parameters: -automated1). Finally, the phylogenetic tree was computed with FastTreeMP (parameters: -gamma -pseudo -spr -mlacc 3 -slownni).
Mapping rate distribution across public cohortsWe generated mapping rate distribution plots using Meteor2 (default parameters), comparing performance between: PRJEB20308 (cohort used in catalogue assembly) and PRNJNA714112 (independent cohort not used in assembly).

title: V-24.0917: Eersel, Stokkelsche Akker Gemeente Eersel. Plangebied Stokkelsche Akker te Eersel. Inventariserend veldonderzoek (verkennende fase)

description: &lt;p&gt;BAAC heeft een archeologisch vooronderzoek in de vorm van een inventariserend veldonderzoek (verkennend booronderzoek) uitgevoerd in het circa 20 ha grote plangebied Stokkelsche Akker te Eersel. Aanleiding voor het onderzoek is een haalbaarheidstoets ten behoeve van het realiseren van een nieuw te bouwen woonwijk.&lt;br&gt;Uit het vooronderzoek is gebleken dat het plangebied op de overgang van een dekzandrug ligt en in zuid(west)elijke richting afhelt naar een fluvioperiglacaal dal met direct ten zuiden hiervan een beekdal. In het plangebied worden hoge en lage enkeerdgronden verwacht. Het plangebied was onderdeel van een akkercomplex en sinds de 19e eeuw zijn in het uiterste westen van het plangebied aanwijzingen voor bebouwing in het plangebied. Het plangebied ligt deels op een terrein met een hoge archeologische verwachting. Ten noorden van het plangebied zijn sporen van bewoning uit de periode bronstijd tot en met middeleeuwen opgegraven. Op basis van de resultaten van het vooronderzoek is een hoge verwachting toegekend aan resten uit het paleolithicum neolithicum tot nieuwe tijd A en in het uiterste westen van het plangebied geldt ook een hoge verwachting voor de nieuwe tijd.&lt;br&gt;Uit het veldonderzoek blijkt dat op het plangebied inderdaad dekzandafzettingen aanwezig zijn, welke al dan niet verspoeld zijn. Een plaggendek is echter alleen aangetroffen in het noorden en het zuidwesten van het plangebied. In het zuiden van het plangebied is onder een circa 30 cm dikke bouwvoor een 10 tot 65 cm dikke oude akkerlaag aangetroffen. Met name in de oostelijke helft is de bodemopbouw deels verstoord door de teelt van sierbomen. In een boring in het noorden van het plangebied is een fragment aardewerk uit de late prehistorie gevonden in de oude akkerlaag. In het centrale en oostelijk deel van het plangebied is een 25 tot 40 dikke bouwvoor aangetroffen die direct in het dekzand van de C-horizont overgaat. Op basis van de resultaten van het veldonderzoek blijft de hoge verwachting gehandhaafd voor de noordelijke helft van het plangebied. De verwachting in de zuidelijke helft van het plangebied is bijgesteld naar middelhoog vanwege het ontbreken van een plaggendek of podzolprofiel.&lt;br&gt;BAAC adviseert om bij bodemverstorende activiteiten die dieper reiken dan 30 cm -mv een vervolgonderzoek door middel van proefsleuven uit te voeren voor het hele plangebied.&lt;/p&gt;

title: Cobalt-based perovskite oxides as catalysts for acidic oxygen evolution reaction

description: Cobalt-based oxides have been investigated as potential alternatives to Ir/Ru-based oxides for catalyzing the oxygen evolution reaction (OER) in acidic media. Past research, however, is mainly focused on the spinel oxide structure so far. Exploring alternative crystal structures is essential for expanding the material library and developing highly efficient OER catalysts for acidic environments. As a proof of concept, we demonstrate that Co-based perovskite oxides can drive acidic OER effectively. Appling hard/soft X-ray absorption spectroscopy (hXAS/sXAS) characterizations, we show that the La and Ce doped SrCoO3 (denoted as LSC and CSC, respectively) have a bulk-average Co oxidation state close to 3+ and surface-dominant low-spin CoIII species. Electrochemical analysis reveals that they only show one Co redox pair, similar to CoOOH in acidic environments. The recorded Tafel slopes are around ~65 mV dec-1, comparable to the benchmarking Ir/Ru-based catalysts. The combination of the spectroscopic and electrochemical findings presented here highlights the important role of low-spin CoIII species in catalyzing OER in acidic environments and contributes to the rational design of non-noble metal OER catalysts.
