Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions

Advanced Materials, EarlyView.
Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

Characteristics of gravity fields in the Jinggu M6.6 earthquake

Geodesy and Geodynamics, 2014
Based on the study of high-precision gravity data obtained from recent studies and the regional gravity network for Yunnan province, a variation in the regional gravity field was identified before the occurrence of the Yunnan Jinggu M6. 6 earthquake.

GOCE data evidence underplating beneath the Paraná basin

, 2012
The Paraná basin in the stable South American Platform accumulated a thick sediment layer during the Paleozoic, with more than 3500 m thickness. In Early Cretaceous the same area experienced a flood basalt volcanism which produced a LIP-(Large Igneous ...

Presentism and Quantum Gravity [PDF]

, 2001
There is a philosophical tradition of arguing against presentism, the thesis that only presently existing things exist, on the basis of its incompatibility with fundamental physics.

Simulated gravity field estimation for Deimos based on spacecraft tracking data

Frontiers in Astronomy and Space Sciences
An accurate gravity field model of Deimos can provide constraints for its internal structure modeling, and offer evidence for explaining scientific issues such as the origin of Mars and its moons, and the evolution of the Solar System.

Artificial gravity field

Results in Physics, 2013
AbstractUsing computer algebra to run Einstein’s equations “backward”, from field to source rather than from source to field, we design an artificial gravity field for a space station or spaceship. Everywhere inside astronauts experience normal Earth gravity, while outside they float freely.

AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing

Advanced Materials, EarlyView.
This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

High-resolution residual terrain model and terrain corrections for gravity field modelling and geoid computation in Niger Republic

Geodesy and Cartography, 2018
In this study, we computed and presented grid maps of high-resolution terrain corrections and residual terrain model (RTM) as short-wavelengths of the gravity field and the geoid in Niger.
