Can Eulerian Eddy Diffusivity Be Inferred From Lagrangian Trajectories?
Journal of Advances in Modeling Earth SystemsLagrangian particle trajectories are widely used to characterize tracer dispersion and mixing driven by mesoscale currents (“eddies”), leading to estimates of eddy diffusivity that can in turn be used in non‐eddy‐resolving and eddy‐permitting ocean ...

Dirac Equation and Fisher Information
EntropyPreviously, it was shown that Schrödinger’s theory can be derived from a potential flow Lagrangian provided a Fisher information term is added. This approach was later expanded to Pauli’s theory of an electron with spin, which required a Clebsch flow ...

A Lagrangian approach to nonlinear modeling of anti-roll tanks
, 2011 This paper presents two novel nonlinear models of u-shaped anti-roll tanks for ships, and their linearizations. In addition, a third simplified nonlinear model is presented. The models are derived using Lagrangian mechanics.

Maslov index on symplectic manifolds infinitesimal Lagrangian manifolds
Современная математика: Фундаментальные направленияThis paper is a summary of the report at the conference “Semiclassical analysis and nonlocal elliptic problems-2023”. The definition of the Maslov index of a Lagrangian manifold as a class of onedimensional cohomologies on it gave rise to numerous works ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study analyses the association between carbon emissions and financial performance in Latin American firms. The scientific literature on this topic is limited, with little evidence available in this geographical region. This study aims to address this research gap by testing hypotheses focused on analysing how Scope 1, 2 and 3 carbon ...

Bayesian inference for ocean transport and diffusivity fields from Lagrangian trajectory data [PDF]
, 2020 Eddy diffusion is commonly used to characterise subgrid-scale mixing of tracer quantities in geophysical fluid simulations. Limited by data availability, estimating eddy diffusivity from observational data remains challenging.

Business Strategy and the Environment, EarlyView.ABSTRACT This study demonstrates how a profitable, lean, and environmentally responsible e‐waste reverse logistics system can be designed using integrated Operations Research (OR) techniques. Addressing the growing urgency of responsible consumption (UN SDG 12) and the projected rise of the e‐waste sector to USD 137.60 billion by 2029, the research ...

Classical Mechanics is Lagrangian; It Is Not Hamiltonian [PDF]
, 2011 One can (for the most part) formulate a model of a classical system in either the Lagrangian or the Hamiltonian framework. Though it is often thought that those two formulations are equivalent in all important ways, this is not true: the ...

SO2 Transfer Enabled by an Easy‐to‐Handle Ionic Liquid
Chemistry – A European Journal, EarlyView.Best of both worlds: The ionic liquid [NEt3Me][Cl(SO2)n] unites the atom economy and low cost of sulfur dioxide with the safety and applicability of common surrogates, streamlining SO2 transfer to access to 3‐sulfolenes, sulfonamides, and SuFEx reagents.
