Dynamic Gravity | Explaining Field Theory: Gravity field, Electric field, and Magnetic field

open access: yesEuropean Journal of Physical Sciences
Purpose: This paper explains the makeup of muon and tau electrons and neutrinos, and proposes the exact reason explaining why neutrino oscillation can occur according to the principles of Dynamic Gravity theory. The only theory of gravity that can and does perfectly calculate all gravity, dark matter, and dark energy perfectly according to all ...

Spacetime and the Philosophical Challenge of Quantum Gravity [PDF]

open access: yes, 2001
We survey some philosophical aspects of the search for a quantum theory of gravity, emphasising how quantum gravity throws into doubt the treatment of spacetime common to the two `ingredient theories' (quantum theory and general relativity), as a 4 ...

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

open access: yesAdvanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...

The gravity field of Mars

open access: yesGeophysical Research Letters, 1975
A complete sixth‐degree spherical‐harmonic model of the gravitational potential of Mars has been produced from an analysis of Doppler data obtained from the radio tracking of the Mariner‐9 spacecraft for over 200 orbital revolutions. The equipotential surface defined by this model is estimated to be accurate to within 100 m below 60° North Latitude and

Autonomous Folding of Soft Matter From Living Polymers

open access: yesAdvanced Materials, EarlyView.
Origami structures are endowed with “living” polymer creases that grow, remodel, and stiffen in response to nutrient solutions. This post‐fabrication growth enables autonomous folding, iterative regrowth, and mechanical tuning involving origami assemblies, such as cranes, Miura‐ori tessellations, rigid and non‐rigid square‐twist patterns, establishing ...

Characteristics of gravity fields in the Jinggu M6.6 earthquake

open access: yesGeodesy 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.

Bioinspired Adaptive Surfaces for Intelligent Liquid Manipulation: Progressing From Passive and Active to Hybrid Strategies

open access: yesAdvanced Materials, EarlyView.
This review examines passive, active, and hybrid liquid manipulation strategies, highlighting hybrid approaches as an emerging route to reconcile energy efficiency with adaptive control. By actively reconstructing passive surfaces to store programmable interfacial energy, hybrid systems enable flexible yet low‐power liquid transport, with perspectives ...

Simulated gravity field estimation for Deimos based on spacecraft tracking data

open access: yesFrontiers 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.
