Autonomous Locomotion of Tensegrity Structure on Low‐Temperature Surfaces

open access: yesAdvanced Robotics Research, EarlyView.
A low‐temperature responsive tensegrity structure (LRTS) is constructed by integrating low‐responsive temperature liquid crystal elastomer (LCE) cables, nonresponsive cables, and stiff rods. The low phase transition temperature of LCE is achieved by introducing a new liquid crystal mesogen.

Waveguide Photoactuators: Materials, Fabrication, and Applications

open access: yesAdvanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

TESS Hunt for Young and Maturing Exoplanets (THYME). XIV. A Comoving-based Age Constraint for KELT-20

open access: yesThe Astronomical Journal
Young stellar moving groups offer unique opportunities to investigate the early evolution of stellar and planetary systems. In continuation of an ongoing effort to age-date compelling planetary systems, we provide an in-depth age analysis of KELT-20—a ...

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

ALMA Reveals an Eccentricity Gradient in the Fomalhaut Debris Disk

open access: yesThe Astrophysical Journal
We present evidence of a negative eccentricity gradient in the debris disk of the nearby A-type main-sequence star, Fomalhaut. Fitting to the high-resolution, archival ALMA 1.32 mm continuum data for Fomalhaut (with a synthesized angular resolution of 0 $

Secular Evolution of Planetary Systems in Binaries

open access: yes, 2007
The orbital eccentricity of a single planet around a component of a stellar binary system with a sufficiently large mutual inclination angle is known to oscillate on a secular timescale through the Kozai mechanism. We have investigated the effects of the Kozai mechanism on double-planet systems in binaries.

Planet–Planet Scattering and Von Zeipel–Lidov–Kozai Migration—The Dynamical History of HAT-P-11

open access: yesThe Astrophysical Journal
The two planets of the HAT-P-11 system represent fascinating dynamical puzzles due to their significant eccentricities and orbital misalignments. In particular, HAT-P-11 b is in a close-in orbit in which tides should have circularized well within the age

Intelligent Maintenance Review for Robots: Multimodal Information, Deep Diagnosis and Embodied Artificial Intelligence

open access: yesAdvanced Robotics Research, EarlyView.
This review maps the methods to monitor robots’ health by fusing vibration, sound, control signals, vision, force, and oil information with artificial intelligence. It identifies deep learning, transfer learning, digital twins, and physics‐informed models as key methodological pathways enabling earlier diagnosis, safer human–robot collaboration, and ...
