Exciting DeePMD: Learning excited-state energies, forces, and non-adiabatic couplings [PDF]

The Journal of Chemical Physics
We extend the DeePMD neural network architecture to predict electronic structure properties necessary to perform non-adiabatic dynamics simulations. While learning the excited state energies and forces follows a straightforward extension of the DeePMD approach for ground-state energies and forces, how to learn the map between the non-adiabatic coupling

Numerical Studies of Propeller Exciting Bearing Forces under Nonuniform Ship’s Nominal Wake and the Influence of Cross Flows

Shock and Vibration, 2017
Propeller exciting forces are the main causes of stern vibrations. In this paper, three-dimension exciting bearing forces of one blade and the whole propeller under nonuniform ship’s wake were predicted, and the influence of cross flows on these exciting

Targeted mechanical forces enhance the effects of tumor immunotherapy by regulating immune cells in the tumor microenvironment

Cancer Biology & Medicine, 2023
Mechanical forces in the tumor microenvironment (TME) are associated with tumor growth, proliferation, and drug resistance. Strong mechanical forces in tumors alter the metabolism and behavior of cancer cells, thus promoting tumor progression and ...

Hydrodynamic Analysis of Two Coaxial Moonpool Floaters Using Theoretical Methodologies

Journal of Marine Science and Engineering, 2023
The present contribution aims at presenting a semi-analytical solution methodology of the linear hydrodynamic diffraction and radiation problems induced by two coaxial moonpool-type floaters subjected to incident waves. The flow field around the floaters

Probing Molecular Excited States by Atomic Force Microscopy [PDF]

Physical Review Letters, 2021
By employing single charge injections with an atomic force microscope, we investigated redox reactions of a molecule on a multilayer insulating film. First, we charged the molecule positively by attaching a single hole. Then we neutralized it by attaching an electron and observed three channels for the neutralization.

Scattering of water waves by a wave energy device consisting of a pair of co-axial cylinders in a uniform water having finite channel width

Journal of Ocean Engineering and Science, 2021
We consider a device which consists of a floating structure over a cylindrical plate placed at a finite height from the impermeable ocean floor. This paper developes the interaction of linear water waves with such a device.

Theoretical Analysis of a Vertical Cylindrical Floater in Front of an Orthogonal Breakwater

Fluids, 2020
This study investigates the effect of an orthogonal-shaped reflecting breakwater on the hydrodynamic characteristics of a vertical cylindrical body. The reflecting walls are placed behind the body, which can be conceived as a floater for wave energy ...

Force Sensor Characterization Under Sinusoidal Excitations [PDF]

Sensors, 2014
The aim in the current work is the development of a method to characterize force sensors under sinusoidal excitations using a primary standard as the source of traceability. During this work the influence factors have been studied and a method to minimise their contributions, as well as the corrections to be performed under dynamic conditions have been

Effects of “S”-Type Bowed Guide Vanes on Unsteady Flow in 1.5-Stage Axial Compressors

Applied Sciences, 2023
In axial compressors, the unsteady flow caused by the interaction between dynamic and static cascades will make the moving vanes subject to periodic forces and increase the risk of high-cycle fatigue fractures. In this study, an “S”-type bowed guide vane

REDUCING VIBRATION TENSION OF PAIRWISE SHROUDED BLADES OF TURBINE

Авіаційно-космічна техніка та технологія, 2020
To reduce the vibration stresses arising in the working blades of turbines during resonant excitations caused by the frequency of passage of the blades of the nozzle apparatus, it is necessary to control the level of aerodynamic exciting forces.
