Effective inertial frame in an atom interferometric test of the equivalence principle

, 2017
In an ideal test of the equivalence principle, the test masses fall in a common inertial frame. A real experiment is affected by gravity gradients, which introduce systematic errors by coupling to initial kinematic differences between the test masses. We

Enhancing Grayscale E‐Beam Lithography: Thermal Treatment of Novolak‐Based Resist for 3D Nanostructures

Advanced Materials Interfaces, EarlyView.
Surface roughness and chemistry of novolak‐based grayscale resists are dependent on both exposure dose and post‐exposure thermal treatment. The observed trends align with the viscoelastic phase separation model and underscore the need to consider both thermodynamic and kinetic factors in resist processing. By tailoring thermal treatment, it is possible

Interfacial Behavior of Methane in Methane/p‐Xylene/Water Systems: First Principles Inspected Using Neutron Imaging and Molecular Dynamics Simulations

Advanced Materials Interfaces, EarlyView.
Pressurized gases reduce interfacial tension (IFT) at the gas‐liquid interfaces, their influence on the liquid–liquid interfaces remains unclear. For model compounds methane, water, and p‐xylene, neutron imaging observation of pressurized three‐phase systems is combined with Molecular Dynamics simulations.

Predicting intermediate wavelength depth using a deep neural network combined with gravity data in the Sea of Japan

International Journal of Digital Earth
Influenced by various geophysical factors, gravity and bathymetry exhibit significant correlations only at certain intermediate wavelengths. In this study, a deep neural network (DNN) combined with multi-source gravity data was used to recovery the ...

Atmospheric Layers in Response to the Propagation of Gravity Waves under Nonisothermal, Wind-shear, and Dissipative Conditions

Journal of Marine Science and Engineering, 2016
We study the atmospheric structure in response to the propagation of gravity waves under nonisothermal (nonzero vertical temperature gradient), wind-shear (nonzero vertical zonal/meridional wind speed gradients), and dissipative (nonzero molecular ...

Synopsis of early field test results from the gravity gradiometer survey system [PDF]

Although the amount of data yielded by the initial airborne and surface tests was modest, it was sufficient to demonstrate that the full gravity gradient tensor was successfully measured from moving platforms both in the air and on the surface.
