Spontaneously generated tensor field gravity [PDF]
Nuclear Physics B, 2011 An arbitrary local theory of a symmetric two-tensor field $H_{ }$ in Minkowski spacetime is considered, in which the equations of motion are required to be compatible with a nonlinear length-fixing constraint $H_{ }^{2}=\pm M^{2}$ leading to spontaneous Lorentz invariance violation, SLIV ($M$ is the proposed scale for SLIV).

Aerospace, 2023 Autonomous navigation and orbit determination are key problems of asteroid exploration missions. Inter-satellite range link is a type of measurement widely used in the orbit determination of Earth satellites, but not so widely used in missions around ...

, 2022 For the construction and maintenance of large-scale infrastructure such as the Gotthard Base Tunnel or the CERN-FCC, it is vital to take into account the influence of the varying gravity field, because most geodetic measurements are referring to the local plumb lines and equipotential surfaces, deviating from purely geometrical positioning by e.g. GNSS.

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.

Dizhen xuebao, 2019 为深入理解研究区的构造运动规律，进一步探求地壳物质可能的运移模式，本文基于Crust1.0地壳结构模型和最新莫霍面深度模型对自由空气重力异常数据进行联合约束，采用三维重力反演技术得到了郯庐断裂带中段的三维密度结构。反演结果显示，研究区的背景场稳定，断裂构造发育部位表现为重力密度低值，特别是营潍断裂带正处于大范围的重力密度低值区并纵贯整个研究区，由此可推断重力密度低值区可指示断裂构造的存在。

Evaluation of globally gridded precipitation data and satellite-based terrestrial water storage products using hydrological drought recovery time [PDF]
Hydrology and Earth System SciencesAccurate precipitation observations are crucial for understanding meteorological and hydrological processes. Most precipitation products rely on station-based observations, either directly or for bias-corrected satellite retrievals.

Quantum gravity from conformal field theory [PDF]
Journal of High Energy Physics, 2018 We bootstrap loop corrections to AdS${}_5$ supergravity amplitudes by enforcing the consistency of the known classical results with the operator product expansion of $\mathcal{N}=4$ super Yang-Mills theory. In particular this yields much new information on the spectrum of double-trace operators which can then be used, in combination with superconformal
