- Description:
- The file named "Raw_Reference+OIDU_Data.xlsx" contains both raw data from the Phenom 300 reference scientific measurements and raw data from measurements by the Icing Detection System (IDS) Optical Icing Detection Unit (OIDU) installed in the Phenom 300. Each tab of the file named "Raw_Reference+OIDU_Data.xlsx" contains data from a specific flight with the flight number in the tab. Each tab contains columns for measurement time (in seconds of the UTC day), 905 nm OIDU signal (in counts), 1525 nm signal (in counts), 1635 nm signal (in counts), flight altitude (in ft), air temperature (in degrees C), liquid water content -LWC (in g/m^3), total water content -TWC (in g/m^3), ice water content -ICW (in g/m^3), and median volume diameter -MVD (in micron)., The file named "Raw_MRU_Data.xlsx" contains raw data from measurements made by the microwave resonator unit (MRU). The various columns contain data from engineering measurements and icing detection measurements. The data scientific relevant are in column A -the time stamp in UNIX time, column B -the time stamp in seconds of the GMT day, column G -the peak resonator frequency (Hz), and column H -the resonance quality factor (non-dimensional)., and The file named "Appendix-C-O_Data_Explained.xlsx" contains processed data from measurements by the Phenom 300 reference scientific measurements and processed data from measurements by the Icing Detection System (IDS) Optical Icing Detection Unit (OIDU) installed in the Phenom 300. As explained in Renno et al. (2025), the raw data was reduced by removing data points reported to contain measurement errors (identified by the NAN code in the data) and in-cloud measurements in which TWC ≤ 0 or MVD ≤ 0 before being analyzed. Each data column is described in the first tab.

- Description:
- During its trajectory, Wind spent a significant amount of time in the magnetotail, where its SupraThermal Ion Composition Spectrometer (STICS) measured the mass and mass per charge of protons, alpha particles, and heavy ions with an energy/charge ratio up to 226 keV/e. Although STICS originally aimed to measure the abundance of these ion species in the solar wind, its measurements within the magnetosphere from 1995 to 2002 help us identify preferential entry between the different solar wind ion species. This study statistically analyzes how the ratio between solar wind heavy ions and alpha particles (Heavies Solar Wind / He2+) varies for different upstream conditions and locations within the magnetosphere: northward vs. southward Interplanetary Magnetic Field (IMF), low vs. high solar wind density (Nsw), low vs. high solar wind dynamic pressure (PDyn), slow vs. fast solar wind (Vsw), and dawn vs. dusk. Our results indicate that the HeaviesSolar Wind enter the magnetosphere more efficiently than He2+ during northward IMF and that the Heavies Solar Wind / He2+ ratios decrease during high PDyn. In addition, the Heavies Solar Wind / He2+ ratios exhibit a dawn-dusk asymmetry, highly skewed towards the dawn side for all upstream cases likely due to charge-exchange processes.

- Description:
- We study the pathophysiology of spinal cord decompression sickness. We saturated ex-vivo bovine spinal cord tissue with nitrogen, partially decompressed the samples to induce bubble formation, and then probed the mechanical response of the surrounding tissue by pressure-cycling.

- Description:
- The ability to accurately measure tibiofemoral angles during various dynamic activities is of clinical interest. The purpose of this study was to determine if inertial measurement units (IMUs) can provide accurate and reliable angle estimates during dynamic actions. A tuned quaternion conversion (TQC) method tuned to dynamics actions was used to calculate Euler angles based on IMU data and these calculated angles were compared to a motion capture system (our “gold” standard) and a commercially available sensor fusion algorithm. Nine healthy athletes were in-strumented with APDM Opal IMUs and asked to perform nine dynamic actions; five participants were used in training the parameters of the TQC method with the remaining four used to test validity.

- Description:
- Reconstructed CT slices for Cranium of Castoroides (University of Michigan Museum of Paleontology catalog number UMMP VP 3110) as a series of TIFF images. Raw projections are not included in this dataset. The reconstructed slice data resulting from a merge of two separate scans are offered here as a series of unsigned 16-bit integer TIFF images. There may be slight differences in voxel grey values between the two parts. The upper left corner of the first image (*_0000.tif) is the XYZ origin.
