Development of a hybrid multi-scale simulation approach for spray processes [PDF]
, 2015 This paper presents a multi-scale approach coupling a Eulerian interface-tracking method and a Lagrangian particle-tracking method to simulate liquid atomisation processes.

Resolvent near zero energy on Riemannian scattering (asymptotically conic) spaces, a Lagrangian approach [PDF]
Pure and Applied Analysis, 2018 We use a Lagrangian regularity perspective to discuss resolvent estimates near zero energy on Riemannian scattering, i.e. asymptotically conic, spaces, and their generalizations.

BRST-BV approach to continuous-spin field
Physics Letters B, 2018 Using BRST-BV approach, massless and massive continuous-spin fields propagating in the flat space are studied. For such fields, BRST-BV gauge invariant Lagrangian is obtained.

Lagrangian approach to local symmetries and self-dual model in gauge invariant formulation [PDF]
, 1997 Taking the St\"uckelberg Lagrangian associated with the abelian self-dual model of P.K. Townsend et al as a starting point, we embed this mixed first- and second-class system into a pure first-class system by following systematically the generalized ...

Lagrangian Formalism in Perturbed Nonlinear Klein-Gordon Equations [PDF]
, 2004 We develop an alternative approach to study the effect of the generic perturbation (in addition to explicitly considering the loss term) in the nonlinear Klein-Gordon equations. By a change of the variables that cancel the dissipation term we are able to

Spontaneous CP breaking in QCD and the axion potential: an effective Lagrangian approach [PDF]
, 2017 A bstractUsing the well-known low-energy effective Lagrangian of QCD — valid for small (non-vanishing) quark masses and a large number of colors — we study in detail the regions of parameter space where CP is spontaneously broken/unbroken for a vacuum ...

Geoscientific Model Development, 2018 . Urban regions are responsible for emitting significant amounts of fossil fuel carbon dioxide (FFCO2), and emissions at the finer, city scales are more uncertain than those aggregated at the global scale.

An Augmented Lagrangian Approach to the Constrained Optimization Formulation of Imaging Inverse Problems [PDF]
IEEE Transactions on Image Processing, 2009 We propose a new fast algorithm for solving one of the standard approaches to ill-posed linear inverse problems (IPLIP), where a (possibly nonsmooth) regularizer is minimized under the constraint that the solution explains the observations sufficiently ...

Relativistic Lagrangian displacement field and tensor perturbations [PDF]
, 2014 We investigate the purely spatial Lagrangian coordinate transformation from the Lagrangian to the basic Eulerian frame. We demonstrate three techniques for extracting the relativistic displacement field from a given solution in the Lagrangian frame ...

Journal of operational oceanography. Publisher: The Institute of Marine Engineering, Science & Technology, 2019 Marine litter is identified as the major ocean pollution today, with a significant impact on the environment. The transport of litter by ocean circulation is still poorly understood, and the management of marine litter remains a major challenge for local
