This dataset provides synthetic radio channel samples generated by ray-tracing simulation, for use in the study of the Future Railway Mobile Communication System (FRMCS). The data were produced by SIRADEL using their InoWave ray-tracing engine, in the framework of two collaborative research projects: 5G-RACOM and 5G-REMORA . 5G-RACOM (5G for Resilient and Green RAil COMmunications) investigates spectrum-efficient, resilient, and robust designs for FRMCS, covering radio propagation and channel modeling at 900 MHz (band n100) and 1900 MHz (band n101) across various railway operational scenarios, GSM-R/FRMCS coexistence, and hybrid FRMCS network solutions. More information: 5G-RACOM - Franco-German Ecosystem for Private 5G Networks . 5G-REMORA (5G-REalistic radio channel MOdels enabled system evaluation for RAilway environments) supports a "zero-on-site testing" approach for FRMCS deployment, combining realistic railway radio channel characterization from on-site sounder measurements, stochastic modeling, and enhanced ray-tracing, targeting the 900-1900 MHz railway frequency bands. More information: ANR Project-ANR-22-CE22-0015 . Dataset content The dataset includes two railway propagation scenarios, both simulated at a 1900 MHz central frequency between a macro-cell base station (BS) located near the track and a dual-polarized antenna mounted on the train rooftop: Montparnasse scenario : An outdoor-to-indoor transition scenario at the edge of the Montparnasse railway station in Paris, covering a 60 m trajectory (30 m outdoor / 30 m indoor) at 20 km/h. Paris scenario : An urban propagation scenario in the south of Paris, covering a 163 m trajectory at 100 km/h, including scattering effects from 22 metallic catenary pylons along the track. Each scenario is provided as a CSV file containing, for each simulated user-equipment (UE) position along the train trajectory, the set of ray-traced multipath components (delay, Doppler shift, azimuth/elevation angles of departure and arrival, and complex path amplitudes for all four V/H polarization combinations), along with UE position, timestamp, and line-of-sight/obstruction status. The channel data is provided as raw propagation output - no transmit power, antenna pattern, or signal bandwidth is applied. The complete CSV field definitions and coordinate/angle conventions are documented in the accompanying file SIRADEL railway channel data format - v1.3.pdf . The data is licensed under a Creative Commons "CC BY-NC-SA 4.0" license, which excludes any commercial use. The users are encouraged to publicly communicate the results of studies based on this channel data; and clearly state the source of the data. If you are using the data, we would pleased you keep us informed, and let us know about the target application.

This deposit contains a dynamically maintained database of vertebrate-virus associations. The VIRION database has been assembled through both reconciliation of static data sets and integration of dynamically updated databases. These data sources are all harmonized against one taxonomic backbone, including metadata on host and virus taxonomic validity and higher classification; additional metadata on sampling methodology and evidence strength are also available in a harmonized format. Data Products: 1) virion.csv.gz - Virion dataset. 2) ncbi_accession.csv.gz - NCBI Accession numbers for virion associations. Linked via AssocID. 3) db_table.csv - Databases used to compile virion. Linked via DatabaseVersion. 4) tax_table.csv.gz - Taxa information for virion. Linked via HashTaxID to HostHashTaxID or VirusHashTaxID.
