This data report presents prokaryotic metagenome-assembled genomes (MAGs) from a hot spring stream with temperatures between 64 and 100°C. The stream water was filtered and the extracted total DNA was sequenced using the Illumina HiSeq 2500 platform. Approximately 80 Gb of raw data were generated, which were subsequently assembled using MEGAHIT v1.2.9. The MAGs were generated using MetaWRAP with binning approaches of MetaBAT2, CONCOCT and MaxBin2. We constructed 25 medium-quality and 24 high-quality archaeal MAGs, and 152 medium-quality and 112 high-quality bacterial MAGs. The fasta files of these MAGs are available in the NCBI database as well as Mendeley Data. Major phyla identified include Bacteroidota, Chloroflexota, Desulfobacterota, Firmicutes, Patescibacteria, Proteobacteria, Spirochaetota, Verrucomicrobiota, Armatimonadota, Nitrospirota, Acidobacteriota, Elusimicrobiota, Planctomycetota, Candidate division WOR-3, Aquificota, Thermoproteota, and Micrarchaeota. This dataset is valuable for studies on thermophilic genomes, reconstruction of biochemical pathways and gene discovery.

We tested both real and model branches of four local tree species in a wind tunnel, for wind speeds up to 20 m/s. The model branches were same-size replicas of the real branches obtained via photogrammetry and 3D-printed or CNC-machined. Real leaves were attached to the models in approximately similar configuration. After comparing the streamwise force, drag coefficient (based on initial frontal area) and streamwise deflection, we found that the models exhibited similar trends to that of the real branches. Although not identical in value, the measurements for the model branches were similar in magnitude to the real branches. In particular, the drag coefficients appeared to approach very similar plateaus. We believe the differences in streamwise force and deflection to be due to the plastic used for the models, as well as perhaps how the leaves were attached to the models. We thus consider these physical models to be generally feasible for studying tree branches.

In order to improve the detection of similar chunks of de-duplication technology, a value evaluation model for chunks is built. On account of the locality characteristic of chunks, a strategy of de-duplication based on the similarity of adjacent chunks is proposed. Experimental results show that effective and feasible strategy greatly increase the throughput, balance the throughput and compression ratio to achieve the desired research objective.

The possibility of using microwave low temperature plasma ( M L T P ) to treat the human hair and achieve the aim of stretching and slenderizing was studied. The parameters such as the moisture regain, electric discharge power, vacuum level, treating time of the MLTP were optimized. The results showed that the optimum treating process was the moisture regain 4. 2%, electric discharge power 50 W, vacuum level 30 Pa and treating time 10 min. The treated human hair under the optimum treating process with MLTP was stretched and slenderized, compared with untreated human hair, the breaking strength had no obvious change, elongation at break was decreased and initial modulus was increased slightly. The room temperature setting degree and boiling water setting degree were increased as well. [ABSTRACT FROM AUTHOR]
