Data from: From the cover: three-dimensional (3d) heparg spheroid model with physiologically relevant xenobiotic metabolism competence and hepatocyte functionality for liver toxicity screening.
Effective prediction of human responses to chemical and drug exposure is of critical importance in environmental toxicology research and drug development. While significant progress has been made to address this challenge using invitro liver models, these approaches often fail due to inadequate tissue model functionality. Herein, we describe the development, optimization, and characterization of a novel three-dimensional (3D) spheroid model using differentiated HepaRG cells that achieve and maintain physiologically relevant levels of xenobiotic metabolism (CYP1A2, CYP2B6, and CYP3A4/5). This invitro model maintains a stable phenotype over multiple weeks in both 96- and 384-well formats, supports highly reproducible tissue-like architectures and models pharmacologically- and environmentally important hepatic receptor pathways (ie AhR, CAR, and PXR) analogous to primary human hepatocyte cultures. HepaRG spheroid cultures use 50–100× fewer cells than conventional two dimensional cultures, and enable the identification of metabolically activated toxicants. Spheroid size, time in culture and culture media composition were important factors affecting basal levels of xenobiotic metabolism and liver enzyme inducibility with activators of hepatic receptors AhR, CAR and PXR. Repeated exposure studies showed higher sensitivity than traditional 2D cultures in identifying compounds that cause liver injury and metabolism-dependent toxicity. This platform combines the well-documented impact of 3D culture configuration for improved tissue functionality and longevity with the requisite throughput and repeatability needed for year-over-year toxicology screening.
Data from: Tracking marine mammals in 3D using electronic tag data
1. Information about at-depth behaviour of marine mammals is fundamental yet very hard to obtain from direct visual observation. Animal-borne multisensor electronic tags provide a unique window of observation into such behaviours. 2. Electronic tag sensors allow the estimation of the animal's 3-dimensional (3D) orientation, depth and speed. Using tag flow noise level to provide an estimate of animal speed, we extend existing approaches of 3D track reconstruction by allowing the direction of movement to differ from that of the animal's longitudinal axis. 3. Data are processed by a hierarchical Bayesian model that allows processing of multisource data, accounting for measurement errors and testing hypotheses about animal movement by comparing models. 4. We illustrate the approach by reconstructing the 3D track of a 52-min deep dive of a Blainville's beaked whale Mesoplodon densirostris adult male fit with a digital tag (DTAG) in the Bahamas. At depth, the whale alternated regular movements at large speed (>1·5 m s -1) and more complex movements at lower speed (<1·5m s-1) with differences between movement and longitudinal axis directions of up to 28inline image. The reconstructed 3D track agrees closely with independent acoustic-based localizations. 5. The approach is potentially applicable to study the underwater behaviour (e.g. response to anthropogenic disturbances) of a wide variety of species of marine mammals fitted with triaxial magnetometer and accelerometer tags.

3D ground reaction force data of walking individuals crossing the vibration-prone experimental pedestrian bridge HUMVIB, Darmstadt, Germany
<p>This data set is obtained within the framework of the DFG research project HUMVIB (Project number 446124066) to investigate human-induced vibrations and human-structure interaction on pedestrian bridges. In total, a set of data from 26 subjects for different walking step frequencies was investigated. Each condition was performed on the vibration-prone HUMVIB Bridge at the Lichtwiese campus of the Technical University of Darmstadt with a vertical natural frequency of 2.02 Hz. Each condition was also performed for the system configuration with the optional center support and consequently much higher frequency of 7.72 Hz. Thereby, each condition was repeated for 10 crossings and with each run 5 single steps were recorded by portable Ground Reaction Force Plates (GRFPs). In this case, the sensor plan <a href="https://zenodo.org/api/records/14049724/draft/files/02_HUMVIB_Bridge_with_GRFP.pdf/content" target="_blank" rel="noopener noreferrer">02_HUMVIB_Bridge_with_GRFP.pdf</a> shows that FP1, FP2, FP4, FP5 and FP6 are hit when crossing a bridge. Therefore, under these walking conditions, FP3 only records the mass inertia due to the bridge acceleration or noisy zero signals as a reference.</p> <p>The measured 3D ground reaction forces have been time-synchronized and measured with a sampling rate of 1,000 Hz. Complementary sensors on the structural response (accelerometers, strain gauges, ...) as well as on the subjects themselves (EMG sensors and MoCap) are less relevant for the analysis of the GRFs and will be published as a supplement after the analysis is completed. However, since FP3 is not hidden by a step of the walking subjects, it can also serve as a structural response sensor and thus not only provide the mass inertia but also the structural acceleration of the bridge. The dataset is well suited for the analysis of GRFs as a function of the tuning or structural acceleration between excitation and natural frequencies of walking individuals on vibration-prone structures. Furthermore, based on the given personal characteristics (height, weight, gender, age), an estimation of the influence of the personal parameters is possible. Finally, based on the size of the sample, the inter- and intra-variability of the persons walking can be investigated for verticals but also horizontal GRFs in general.</p>

BARREL 3D X-ray Spectrometer (MSPC) Bremsstrahlung X-ray Spectrum Medium Time Resolution, Level 2, 4 s Data
MSPC: 48 channels of medium time resolution, 4 s, Bremsstrahlung X-ray spectra detected with a NaI Scintillator. The nominal energy range covered by the 48 channels ranges from 0 MeV to 4 MeV. All channels are combined to a single variable named MSPC.The BARREL Mission was a multiple-balloon investigation designed to study electron losses from Earth's Radiation Belts. Selected as a NASA Living with a Star Mission of Opportunity, BARREL was designed to augment the Radiation Belt Storm Probes, RBSP, mission by providing measurements of the spatial and temporal variations of electron precipitation from the radiation belts. The RBSP mission has since been renamed the Van Allen Probes mission. Each BARREL balloon carried an X-ray spectrometer to measure the bremsstrahlung X-rays produced by precipitating relativistic electrons as they collide with neutrals in the atmosphere, and a DC magnetometer to measure ULF-timescale variations of the magnetic field. BARREL observations collected near latitudes close to either the antarctic and arctic circles at stratospheric altitudes at about 30 km. The BARREL instrumentation provided the first balloon measurements of relativistic electron precipitation while comprehensive in situ measurements of both plasma waves and energetic particles were available. Also, the BARREL data has been used to characterize the spatial scale of precipitation at relativistic energies.The initial pair of balloon campaigns that were conducted initially during the Austral summer months of January and February of 2013 and 2014 with launches from two stations located in Antarctica: the British base located at Halley Bay on the Brunt Ice Shelf and the South African SANAE IV base (SANAE stand for South African National Antarctic Expedition) located in Vesleskarvet, Queen Maud Land. For the 2013 and 2014 the balloon campaigns, the launch plan was designed to maintain an array with about five payloads spread across about six hours of magnetic local time, MLT, in the region that magnetically maps to the radiation belts. Thus, the BARREL balloon constellation constituted an evolving and slowly moving array able to study relativistic electron precipitation from the radiation belts.Later campaigns were undertaken in 2015 and 2016 from the Esrange Space Center located in Kiruna, Sweden. The 2015 and 2016 campaigns were undertaken in coordination with the Van Allen Probes mission, the European Incoherent Scatter Scientific Association, EISCAT, incoherent scatter radar system, and other ground and space based instruments. Seven balloon launches occurred during the August 2015 BARREL campaign. A total of eight flights occurred during August 2016.Summing over the four BARREL campaigns, over 50 small, approximately 20 kg, stratospheric balloons were successively launched. The website creeated and hosted by A.J. Halford (see Information URL below) reports that: "By the end of the campaigns, there were over 90 researchers coordinating on a daily basis with the BARREL team working on 7 different satellite missions, 1 other balloon mission, and way too many ground based instruments to count."

BARREL 3D Ephemeris (EPHM) Geographic and Magnetic Coordinates, Level 2, 4 s Data
Geographic and Magnetic Coordinates: The ephemeris data products, which include the balloon epoch time, latitude, longitude, and altitude, are each returned from the payload once every 4s. Geographic coordinates are obtained from an onboard Global Positioning System, GPS, unit.
