Radiation‐Resistant Aluminum Alloy for Space Missions in the Extreme Environment of the Solar System

Advanced Materials, EarlyView.
A novel ultrafine‐grained aluminum crossover alloy exhibits unprecedented radiation resistance and mechanical stability under extreme irradiation doses up to 100 dpa. The exceptional resilience arises from thermodynamically stable T‐phase precipitates, enabling lightweight structural materials for next‐generation spacecraft and extraterrestrial ...

HPT: A High Spatial Resolution Multispectral Sensor for Microsatellite Remote Sensing

Italian National Conference on Sensors, 2018
Although nano/microsatellites have great potential as remote sensing platforms, the spatial and spectral resolutions of an optical payload instrument are limited. In this study, a high spatial resolution multispectral sensor, the High-Precision Telescope

Microstructures and mechanical properties of pure tantalum processed by high-pressure torsion

, 2014
A body-centred cubic (BCC) structure metal, tantalum, was processed by high- pressure torsion (HPT) at room temperature with different numbers of rotations. The microstructural evolution was studied by electron backscatter diffraction (EBSD).

Comparative Single‐Cell Transcriptomic Atlas Reveals the Genetic Regulation of Reproductive Traits

Advanced Science, EarlyView.
A cross‐species single‐cell transcriptomic atlas of reproductive and central nervous system tissues from sheep and humans reveals conserved cellular programs and regulatory networks that regulated fertility. Integration with GWAS for sheep lifetime average litter size identifies UNC5–SLIT–BMP signaling as a core pathway coordinating neuroendocrine ...

Recurrent Constellations of Embryonic Malformations (RCEM): Teratogenicity Linked to Transient Hypoxia and Hormone Pregnancy Tests Agrees With RCEM and Suggest a Reactive Oxygen Species Pathogenesis. [PDF]

Birth Defects Res
ABSTRACT Background No consistent genetic etiology has been found for a group of six different conditions in humans with multiple malformations called “recurrent constellations of embryonic malformations” (RCEM). Recent studies indicate hypoxia/reoxygenation and generation Reactive Oxygen Species (ROS) as an underlying mechanism for RCEM with the ...

Crystal structure of the N-terminal domain of human CDC73 and its implications for the hyperparathyroidism-jaw tumor (HPT-JT) syndrome

Scientific Reports, 2017
CDC73/Parafibromin is a critical component of the Paf1 complex (PAF1C), which is involved in transcriptional elongation and histone modifications. Mutations of the human CDC73/HRPT2 gene are associated with hyperparathyroidism-jaw tumor (HPT-JT) syndrome,

Monolithic arrays of surface emitting laser NOR logic devices [PDF]

, 1993
Monolithic, cascadable, laser-logic-device arrays have been realized and characterized. The monolithic surface-emitting laser logic (SELL) device consists of an AlGaAs superlattice lasing around 780 nm connected to a heterojunction phototransistor (HPT ...
