Ultrafast Pulsed Laser Annealing of Pd100-xSix Thin Films: raw and processed XRD data from PETRA III P07 experiment

0.00

Liubchenko, Oleksii · Jacyna, Iwanna · Albert, Thies Johannes · et al.

5 files · 7.0 MB · zip

This repository contains the underlying research dataset for the publication "Ultrafast Pulsed Laser Annealing of Pd100-xSix Thin Films" (Acta Physica Polonica A, Vol. 148, No. 3, 2025). The data comprises raw and processed high-energy synchrotron X-ray diffraction (XRD) measurements collected at beamline P07 (High-Energy Material Science, Experimental Hutch 2) of the PETRA III storage ring at DESY (Hamburg, Germany) under Proposal ID 20230294 (Beamtime ID 11017285). The experiment utilized a Dectris Pilatus CdTe 2M 2D detector to record spatial area mapping profiles crossing directly through laser-irradiated spots on Pd100-xSix thin films of various chemical compositions (pure Pd reference, Pd97Si03, Pd95Si05, and Pd90Si10). The dataset is systematically organized into four separate components: 1. Calibration data: PyFAI .poni geometry files, master mask arrays, and CeO2 standard reference states. 2. Raw data: Unprocessed 2D Pilatus detector image sequences and experimental runtime logs mapping the full spatial profiles. 3. Integrated 1D patterns: Azimuthally integrated Intensity vs. 2-Theta, including raw integration matrices, global integration parameters (JSON format), and files where the substrate background was subtracted. 4. Data analysis workflows: Working directories for Profex/BGMN Rietveld phase refinement files, structure definitions, and the specific amorphous background pattern (bkg.xy, corresponding to an unannealed Pd83Si17 sample) used to isolate thin-film metallic glass fractions. While the raw sequences and integrated patterns contain the complete sequence of spatial steps recorded across the sample area (covering the area far from the laser center, passing through the boundary, and moving completely through the irradiated spot zone), only a selected subset of scan coordinates was utilized for the final figures in the journal publication. All files are provided in their entirety to ensure complete open-science transparency. Full details regarding structural tracking parameters, coordinate file tracking nomenclature, and technical hardware setups are outlined in the accompanying plain-text README.txt file. This research was funded in whole or in part by the National Science Centre (NCN), Poland, under the OPUS 22 funding scheme (Grant No. 2021/43/B/ST5/02480).

We have investigated an IgG4-RD (IgG4-RD) cohort by our multi-parameter microbiota flow cytometry approach to characterise the microbiota on single-cell level for attributes of the disease. The microbiota is isolated from stool samples and stained according to the published protocol for (a) host immunoglobulins IgA1, IgA2, IgM, IgG and (b) agglutinin binding to mannose, galactose or N-Acetyl-glucosamine surface sugar moieties. For all samples we also determined the microbiome composition by 16S rRNA (V3-V4) sequencing on the illumina MiSeq platform. We provide the raw .fcs and FASTQ files of 40 IgG4-RD patients. For comparison we additionally analysed 36 healthy donors. All .fcs files were generated on BD Influx®. The metadata is collected in the provided meta.csv. The staining parameters are summarized in provided panel.csv.

Saha, Sudipto · Raghava, Gajendra

1 files · 186 KB · zip

VICMpred: SVM-Based Prediction of Functional Proteins of Gram-Negative Bacteria Using Amino Acid Patterns and Composition VICMpred is a computational web server developed for predicting the major functional classes of Gram-negative bacterial proteins from amino acid sequences. The tool classifies Gram-negative bacterial proteins into four broad functional categories: virulence factors, information molecules, cellular process proteins, and metabolism-related proteins. VICMpred uses support vector machine-based models trained on amino acid composition, dipeptide composition, and class-specific tetrapeptide patterns. Web Server: https://webs.iiitd.edu.in/raghava/vicmpred/ Citation Saha, S., and Raghava, G. P. S. VICMpred: An SVM-based method for the prediction of functional proteins of Gram-negative bacteria using amino acid patterns and composition. Genomics, Proteomics & Bioinformatics, 4(1), 42-47, 2006. https://doi.org/10.1016/S1672-0229(06)60015-6 About the Research Functional annotation of proteins is one of the major challenges in the post-genomic era. Due to the rapid growth of protein sequence databases, experimental functional characterization of every newly discovered protein is not practical. Traditional methods such as BLAST, FASTA, and PSI-BLAST depend on sequence similarity. However, proteins with similar functions may show poor sequence similarity, making direct function prediction difficult. VICMpred was developed as a direct function prediction method for Gram-negative bacterial proteins. Instead of only predicting subcellular localization, it predicts broad biological functions directly from protein sequence features. Data Compilation: The final dataset contained 670 non-redundant Gram-negative bacterial proteins. These included 255 cellular process proteins, 60 information molecules, 285 metabolism proteins, and 70 virulence factors. Methodology: VICMpred uses support vector machine-based models trained on amino acid composition, dipeptide composition, PSI-BLAST similarity search, class-specific tetrapeptide patterns, and hybrid combinations of these features.

GIFT-BDS: A high-resolution TEC and Gradient Ionospheric Index dataset over China derived from BeiDou GEO fixed-geometry observations

0.00

Li, Zhiyao · Wang, Ningbo · Zhong, Jiahao

6 files · 48 MB · docx, zip

GIFT-BDS is a regional ionospheric total electron content (TEC) and TEC-gradient dataset over China derived from BeiDou geostationary Earth orbit (GEO) observations and a dense ground-based GNSS receiver network. The dataset is designed to provide high-resolution observations of ionospheric TEC variability and horizontal TEC-gradient structures over China and adjacent regions. The versioned release covers the period from 19 July 2024 to 31 December 2025, corresponding to DOY 201 of 2024 to DOY 365 of 2025. The geographical coverage is 15°N-50°N and 95°E-135°E. The dataset is provided in daily NetCDF files and contains two product levels. Level-1 products provide observation-level GEO-derived slant TEC (STEC) and rate of TEC index (ROTI) records for individual receiver-GEO satellite lines of sight, with a temporal resolution of 30 s. Level-2 products provide gridded regional TEC and TEC-gradient variables, including VTEC, VTEC t , ROTI, GIX, GIX std , GIX x , GIX y , GIX t,x , and GIX t,y , with a temporal resolution of 15 min. IPP-based variables are provided on a 1° × 1° grid, while inter-IPP-gradient variables are provided on a 0.25° × 0.25° grid. The main processing steps include observation screening, cycle-slip and data-gap detection, continuous-arc segmentation, carrier-to-code leveling, satellite and receiver DCB correction, IPP calculation, inter-IPP pair selection, gradient estimation, and gridding. Quality control is applied before release. Missing values may occur because of station outages, data gaps, quality-control exclusions, or insufficient valid samples within a grid cell. Users should check the NetCDF variable attributes, including units and fill values, before analysis. The dataset is suitable for regional ionospheric studies, TEC-gradient monitoring, space-weather-related analyses, and investigations of ionospheric effects on GNSS positioning applications.

HYPER-Z4c Public Reproducibility Archive for Hyperboloidal Z4c Evolution and Direct Scri Waveform Extraction

Ahmad, Mushtaq

2 files · 16 MB · zip

This archive is the public reproducibility package for the manuscript "HYPER-Z4c: A Paper-I Reproducible Constraint-Energy-Ledger Framework for Hyperboloidal Z4c Evolution and Direct Scri Waveform Extraction," prepared for submission to the Journal of Scientific Computing. The archive contains the manuscript source, Online Resource 1 source, publication figures, processed CSV/JSON validation records, waveform-level comparison summaries, metric-worldtube readiness audit records, figure-generation scripts, convergence-fit reproduction scripts, environment files, checksum manifests, and a one-command reproduction workflow. The package supports the methods-paper evidence for a stage-synchronous constraint-energy ledger for hyperboloidal Z4c evolution, scri-compatible SAT closure, full-discrete finite-part regularization, evolved-cut BMS waveform extraction, official SXS/SpECTRE Ext-CCE waveform-level comparison, and a separate CceR0207.h5 metric-worldtube input-readiness audit. The archive does not claim a completed same-spacetime HYPER-Z4c-to-SPECTRE-CCE binary-black-hole validation. The manuscript treats the official Ext-CCE waveform-level comparison and the metric-worldtube readiness audit as separate evidence categories. A matched same-spacetime worldtube-to-CCE comparison remains future work. A minimal reproduction workflow verifies the checksum manifest, runs archive smoke tests, recomputes headline convergence-fit quantities, and regenerates the main figures from the archived records.
