title: Draft Genome Sequences of Clinical Enterobacteriaceae Isolates Harboring Carbapenemase Genes (KPC, NDM, IMP, OXA)

description: This dataset contains whole-genome shotgun sequencing data for nine clinical Enterobacteriaceae isolates, each carrying a major carbapenemase resistance gene (KPC, NDM, IMP, or OXA). The isolates were obtained from hospital settings. Sequencing was performed on the Illumina NovaSeq 6000 platform with a 350 bp insert library, generating 150 bp paired-end reads.Bioinformatic analysis included quality filtering, de novo genome assembly using SOAPdenovo2, SPAdes, and ABySS followed by integration with CISA, and genome component prediction (coding genes, ncRNAs, repeat sequences, genomic islands, prophages, CRISPRs). Functional annotation was performed against multiple databases including NR, Swiss-Prot, COG, KEGG, GO, TCDB, CAZy, Pfam, and pathogenicity-related databases (PHI, VFDB, ARDB, CARD). Secretion systems (T1SS-T7SS) and secondary metabolite clusters were also predicted.The assembled draft genomes range in size from approximately 5.3 to 5.6 Mb, with contig N50 values between 80-170 kbp, and contain between 5,300-5,700 predicted protein-coding genes.These data provide valuable resources for studying the genomic epidemiology, antimicrobial resistance mechanisms (particularly carbapenem resistance), virulence factors, and comparative genomics of multidrug-resistant Enterobacteriaceae in clinical environments.

title: 小白菜土壤根际微生态

description: Nucleic acid was extracted from rhizosphere soil samples using the MagBeams FastDNA Kit for Soil assay kit; For the extracted DNA, the molecular size was judged by 0.8% agarose gel electrophoresis, and the DNA was quantified by Nanodrop. Select the highly variable V3-V4 regions of the bacterial 16S rRNA gene for sequencing. Primers used for PCR amplification: 338F (5 '- ACTCCTACGGGAGGCAGCA-3'), 806R (5 '- GACTACHVGGGTWTCTAAT-3'). Quantify PCR products using Quant iT PicoGreen dsDNA Assay Kit, then mix samples according to the required data volume for each sample, and build libraries using Illumina's TruSeq Nano DNA LT Library Prep Kit. Perform 2 × 250bp double ended sequencing using NovaSeq 6000 SP Reagent Kit (500 cycles) on Illumina NovaSeq machine. The original sequence data is decoded using the Demux plugin, primer excision is performed using the cutadapt plugin, and then the sequence is processed using the DADA2 plugin for quality filtering, denoising, concatenation, and chimerism removal. Merge the obtained sequences with 100% sequence similarity to generate characteristic sequences ASVs and abundance data tables.

title: Structural Evolution Regulation of χ-Fe5C2 and θ-Fe3C in the Reverse Wa-ter-Gas Shift Reaction
title: χ-Fe5C2与θ-Fe3C在逆水煤气变换中的结构演变规律

description: Iron-based catalysts often undergo dynamic carburization and oxidation phase transitions in a CO2/H2 atmosphere. The identification of the active phase and the control of stability remain key challenges affecting their industrial application. This study employed a gas-solid carburization method to prepare high-purity single-phase χ‑Fe5C2 (Hägg carbide) and θ‑Fe3C (cementite), with their structural purity systematically confirmed by XRD and Mössbauer spectroscopy (MES). Using techniques including fixed-bed reactor tests (H2/CO2=1, 0.1 MPa, 270–420 °C), pulse experiments (270 °C), and in-situ XRD (10% CO2/He, 340 °C), the catalytic performance and structural evolution pathways of these carbides in the reverse water-gas shift (RWGS) reaction were thoroughly investigated. The results indicate that χ‑Fe5C2 exhibits higher RWGS activity but is more susceptible to oxidation during the reaction. In contrast, θ‑Fe3C demonstrates stronger anti-oxidation stability but lower RWGS activity. Under RWGS conditions with H2, θ‑Fe3C can partially transform into χ‑Fe5C2. However, in 10 % CO2 atmosphere, both carbides are directly oxidized to Fe3O4, with no observed phase transformation between the iron carbides. These findings reveal the differences in the evolution mechanisms of χ‑Fe5C2 and θ‑Fe3C under different atmospheres, providing experimental basis for the regulation of phase structure and optimization of operational stability in iron-based Fischer-Tropsch and RWGS catalysts.

title: Liquid crystal polarization gratings with wide incidence angle and high diffraction efficiency
title: Liquid crystal polarization gratings with wide incidence angle and high diffraction efficiency

description: Liquid Crystal Polarization Gratings (LCPGs) are highly efficient and versatile liquid crystal devices frequently employed in diverse technologies including light field regulation, beam polarization, and laser radar. A three-layer multi-twist structure of LCPG was prepared using a 266 nm laser interference exposure method, resulting in two types of LCPGs with periods of 7μm and 15μm respectively. Subsequent testing with a 1064 nm wavelength laser and comparison with simulations revealed that the polarization grating can sustain high diffraction efficiency within an incident angle of ±30° at the 1064 nm wavelength. This research paves a way for the applications such as laser radar and beam polarization.

title: Robust phylogeny from 481 nuclear genes and plastomes refines infrageneric classification and species delimitation in Chinese hawthorns (Crataegus, Rosaceae)
title: 基于481个核基因与质体组的稳健系统发育分析重塑中国山楂属（蔷薇科）属下分类与物种界定

description: Crataegus L. (hawthorns) is a taxonomically challenging genus within the Rosaceae family, exhibiting extensive morphological variation, frequent hybridization, and polyploidy. In China, approximately 17–18 species are recognized, but their subgeneric classification and species boundaries remain unresolved. To clarify these relationships, we analyzed 481 nuclear genes, 73 plastid coding sequences, and comprehensive plastome dataset for 17 Chinese Crataegus species to date. Phylogenomic analyses of both nuclear and plastid data produced well-supported trees that refine the taxonomy and elucidate evolutionary relationships within the genus. All Chinese species are resolved within two subgenera, C. subg. Crataegus and C. subg. Sanguineae, although most currently recognized species are not monophyletic, reflecting complex reticulate evolution involving hybridization and polyploidy. Integrating phylogenomic and morphological evidence, we provide an updated taxonomic synopsis of Chinese Crataegus, describe one new species, five new combinations, and designate 31 lectotypes. This study establishes a robust framework for future systematic, conservation, and horticultural research on this ecologically and economically important lineage.

title: 2024-2025, Goat intestinal fecal microbiota sequencing

description: The collected fecal samples were sent to Novogene for amplicon sequencing analysis of the V3-V4 region of the bacterial 16S rRNA gene. The sequencing results were used to construct libraries and perform quantitative analysis. Based on the required effective library concentration and data volume, quantified libraries were pooled and sequenced on the Illumina MiSeq platform. Raw data were processed using Fastp software to filter and remove chimeric sequences, yielding final high-quality valid data. Additionally, denoising was performed with DADA2 in QIIME2 software (version QIIME2-20202) to obtain Amplicon Sequence Variants (ASVs). Taxonomic annotation was conducted using the QIIME2 software. The relative abundance of microbial taxa was calculated as follows: at a given taxonomic level (phylum, class, order, family, or genus), the relative abundance of a specific species was defined as the number of tags corresponding to an ASV divided by the total number of tags clustered from all ASVs in the sample. The H group represents fecal samples from healthy goats, while the C.p group represents fecal samples from clinically abscess-affected goats.
