Stochastic reconstruction of gappy Lagrangian turbulent signals by conditional diffusion models

open access: yesCommunications Physics
Understanding and predicting the motion of small objects in turbulent flows is essential for applications in atmospheric science and oceanography. However, missing velocity data along their trajectories remains a major challenge.

Semi‐analytical solution for the stability of deep vertical shaft considering time‐dependent rock‐structure interaction

open access: yesDeep Underground Science and Engineering, EarlyView.
A novel cavity contraction solution and multilayer shaft wall model were developed to analyze deep shaft stability, considering rock viscosity, support structures, and water pressure, with successful validation through a Hulusu Coal Mine case study.

A safe reinforcement learning approach for autonomous navigation of mobile robots in dynamic environments

open access: yesCAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract When deploying mobile robots in real‐world scenarios, such as airports, train stations, hospitals, and schools, collisions with pedestrians are intolerable and catastrophic. Motion safety becomes one of the most fundamental requirements for mobile robots.

From distant shores to an emerging island: the role of surface and subsurface transport in modeling seed dispersal

open access: yesEcography, EarlyView.
Long‐distance seed dispersal by ocean currents plays a critical role in structuring coastal plant communities. As direct observations of this phenomenon are infeasible, numerical modeling is a valuable tool. Here, we use Lagrangian particle tracking to examine the colonization of the newly forming island Norderoogsand (German Bight, Wadden Sea) by five

Lagrangian analysis and prediction of coastal and ocean dynamics (LAPCOD)

open access: yes, 2007
IntroductionIt was during the 1999 Liege Colloquium on, “Three-Dimensional Ocean Circulation: Lagrangian measurements and diagnostic analyses,” that a number of researchers started to discuss the idea of having a meeting centered on studying the ocean ...

Effects Of Subgrid-Scale Modeling On Lagrangian Statistics In Large-Eddy Simulation [PDF]

open access: yes, 2008
The application of large-eddy simulation (LES) to turbulent transport processes requires accurate prediction of the Lagrangian statistics of flow fields.

Phosphoryl Halogen and Hydrogen Bonding Controls the Solid‐State Structures of Aryl Halide‐Containing Phosphonates

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Intramolecular (RO)2PO→Halogen interaction versus intermolecular (RO)2PO···HOH hydrogen bonds. Although the O···I distance is shorter than the sum of the van der Waals radii of the atoms involved, there is no covalency involved in this interaction.

Routh Reduction by Stages

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
This paper deals with the Lagrangian analogue of symplectic or point reduction by stages. We develop Routh reduction as a reduction technique that preserves the Lagrangian nature of the dynamics.

Lectures on special Lagrangian geometry

open access: yes, 2001
We introduce special Lagrangian submanifolds in C^m and in (almost) Calabi-Yau manifolds, and survey recent results on singularities of special Lagrangian submanifolds, and their application to the SYZ Conjecture.

The Seepage Characteristics of Single Rough Joint of Granite Based on NMR Technology: A Modified Cubic Law

open access: yesEnergy Science &Engineering, EarlyView.
The low‐field nuclear magnetic resonance (NMR) measurements are applied to investigate the seepage characteristics of the single rough joint. The purpose of this paper is to investigate the seepage characteristics of granite specimens with single‐joint channel under the different roughness, confining pressures and seepage pressures.
