From Complex Shaping to Mirror Finish: Additive Manufacturing of Aerospace‐grade Cf/SiC Space Optics
Advanced Science, EarlyView.An integrated additive manufacturing route combines selective laser sintering, engineered interphases, and optimized silicon infiltration to fabricate complex Cf/SiC composites. The approach enables precise shaping, high mechanical performance, and excellent optical reflectivity, offering a scalable solution for advanced aerospace optics with both ...

Classification of Chandra X-Ray Sources in Cygnus OB2
The Astrophysical Journal Supplement Series, 2023 We have devised a predominantly Naive Bayes−based method to classify X-ray sources detected by Chandra in the Cygnus OB2 association into members, foreground objects, and background objects.

Multimodal Locomotion of Soft Robots
Advanced Intelligent Systems, EarlyView.This review comprehensively surveys recent advances in multimodal locomotion within soft robotics. Typical locomotion modes are summarized and categorized. Furthermore, the underlying mechanisms enabling multimodal locomotion are discussed and classified into three primary categories: active control‐based, reconfiguration‐based, and environment ...

Soft X-ray telescope (SXRT) [PDF]
The soft X-ray telescope (SXRT) will provide direct images of the solar corona with spatial resolution of about 1 arcsecond. These images will show the global structure of the corona, the location and area of coronal holes, and the presence of even the ...

X-ray and gamma-ray orbital variability from the gamma-ray binary HESS J1832-093
, 2020 Context. Gamma-ray binaries are systems composed of a massive star and a compact object whose interaction leads to particle acceleration up to relativistic energies. In the last fifteen years, a few binaries have been discovered to emit at high energies,

Discovery of an Energetic Pulsar Associated with SNR G76.9+1.0 [PDF]
, 2011 We report the discovery of PSR J2022+3842, a 24 ms radio and X-ray pulsar in the supernova remnant G76.9+1.0, in observations with the Chandra X-ray telescope, the Robert C. Byrd Green Bank Radio Telescope, and the Rossi X-ray Timing Explorer (RXTE). The

Advanced Intelligent Systems, EarlyView.Female desert locusts dig underground to lay their eggs. They displace soil, rather than removing it, to create a tunnel. We analyze burrowing dynamics and 3D kinematics and design a locust‐inspired hybrid soft–stiff robot that reproduces this mechanism. The results show the natural strategy minimizes energy, whereas alternative patterns raise costs up
