Type I interferons (IFNs) initiate immune responses to viral infections. Their effects are mediated by the type I IFN receptor, IFNAR, comprised of two subunits: IFNAR1 and IFNAR2. One or both chains of the sheep IFNAR were disrupted in fetal fibroblast lines using CRISPR/Cas9 and 12 lambs were produced by somatic cell nuclear transfer (SCNT). Quantitative reverse transcription-polymerase chain reaction for IFN-stimulated gene expression showed that IFNAR deficient sheep fail to respond to IFN-alpha. Furthermore, fibroblast cells from an IFNAR2^−/− fetus supported significantly higher levels of Zika virus (ZIKV) replication than wild-type fetal fibroblast cells. Although many lambs have …

Pando's Pulse: Vital Signs Signal Need For Course Correction At World-Renowned Aspen Forest, Paul C. Rogers

Aspen Bibliography

Upland aspen (Populus spp.) forests contribute significantly to biodiversity in their circumboreal role as keystone species. As aspen ecosystems flourish or diminish, myriad dependent species follow suit. The 43-hectare Pando aspen (Populus tremuloides Michx.) clone in Utah, USA, is thought to be the largest living organism on earth, but is faltering due to chronic herbivory. Long-term resilience in aspen communities, including Pando, rests on successful recruitment of vegetative suckers that are nutritiously desirable to browsing ungulates. Here, I evaluate aspen reproduction alongside numerous vital indicators of Pando's status in the first trend assessment of this embattled iconic forest. …

In this work, we describe the key requirements for trusting imagery and present a hardware design and a system of controls that meet those requirements of trust for Earth imaging satellites. Our trusted hardware provides assurance of capture time, location, and preserves the content and origin by capturing …

Implementation And Characterization Of Commercial Off-The-Shelf Inertial Measurement Units For The Attitude Determination System Of The Move-Iii Cubesat, Natalia Piotrowski

Small Satellite Conference

This paper determines a suitable Inertial Measurement Unit (IMU) for the Attitude Determination and Control System (ADCS) of the third satellite generation of the Munich Orbital Verification Experiment (MOVE). The ADCS is required to provide an attitude determination with an accuracy of < 1°, which has to be achieved with both IMUs and sun sensors, at a low price, due to a low financial budget. In the context of this work, the three IMUs the BNO055, ICM20948 and LSM9DS1 are selected and analyzed. Additionally, the LIS3MDL magnetometer and the BMI088 gyroscope are used for further analysis and comparison. The error coefficients of each sensor measurement are initially calculated through the Allan variance, and these are then verified through Welch’s power spectral density estimate, simulations, and additional sensor measurements. Further temperature experiments are performed to characterize the behaviour of the sensor under changing temperatures. Evaluating the most accurate error coefficients found the BNO055 gyroscope to be the least affected by the white noise compared to the remaining gyroscopes. The LSM9DS1 appears to be the sensor least influenced by the random walk and white noise term among the magnetometers. The BNO055 magnetometer is the comparatively least affected by temperature changes, while the BMI088 appears the most stable amongst the gyroscopes. Finally, the BNO055 IMU is recommended to the ADCS of the MOVE-III CubeSat. It appeared to be the least influenced by different error sources and the ambient temperature.
