Interference of Electromagnetic waves in the background of the gravitational waves [PDF]

open access: yesarXiv, 2018
Based on the relationship between proper distance and coordinate distance, the geometrical phenomenon caused by the passing gravitational waves can not be observed locally. The electromagnetic wave equations in the background gravitational waves are studied.

Thermal Gravitational Waves from Primordial Black Holes

open access: yes, 2010
Thermal gravitational waves can be generated in various sources such as, in the cores of stars, white dwarfs and neutron stars due to the fermion collisions in the dense degenerate Fermi gas.

Toward Autonomous Self‐Healing in Soft Robotics: A Review and Perspective for Future Research

open access: yesAdvanced Intelligent Systems, EarlyView.
In this article, five different phases (damage detection, cleaning, damage closure, material healing, and healing assessment) are investigated to have an autonomous self‐healing at the system level with the focus on soft robotics. It delves into the importance of each phase, why and where they matter, and reviews relevant technologies that enable ...

Chiral Primordial Gravitational Waves from a Lifshitz Point

open access: yes, 2009
We study primordial gravitational waves produced during inflation in quantum gravity at a Lifshitz point proposed by Ho${\rm\check{r}}$ava. Assuming power-counting renormalizability, foliation preserving diffeomorphism invariance, and the condition of ...

Tunable Mechanism Enables Robust Surface Perching Under Different Landing Impacts and Orientation Misalignment

open access: yesAdvanced Intelligent Systems, EarlyView.
A passive, tunable perching mechanism enables aerial robots to reliably perch onto smooth surfaces. The design integrates a bistable mechanism with a soft suction cup and SMA actuators for active tuning. Experiments demonstrate robust performance by adapting to varying contact speeds and surface orientation misalignments, enabling diverse perching ...

Interaction of light with gravitational waves [PDF]

open access: yesarXiv, 2013
The physical properties of electromagnetic waves in the presence of a gravitational plane wave are analyzed. Formulas for the Stokes parameters describing the polarization of light are obtained in closed form. The particular case of a constant amplitude gravitational wave is worked out explicitly.
