Natural Lagrangians for quantum structures over 4-dimensional space-time [PDF]
Rendiconti di Matematica e delle Sue Applicazioni, 1998 The natural quantum Lagrangians which appear in Einstein general relativistic quantum mechanics are classified by using methods of gauge-natural bundles and natural operators.

A hybrid Eulerian–Lagrangian numerical scheme for solving prognostic equations in fluid dynamics [PDF]
Geoscientific Model Development, 2013 A new hybrid Eulerian–Lagrangian numerical scheme (HEL) for solving prognostic equations in fluid dynamics is proposed. The basic idea is to use an Eulerian as well as a fully Lagrangian representation of all prognostic variables.

Scattering‐Enhanced Light Extraction for Radiative Thermal Load Mitigation in Fluorescent Films
Advanced Science, EarlyView.Scattering‐enhanced light extraction overcomes total internal reflection limitations in fluorescent films, expanding the sub‐ambient cooling color range from 26.7% to 64.9% in CIE 1931 space. Optimal TiO2 nanoparticle doping (0.5 wt.%) achieves 85.9% light extraction efficiency and 89.5% visible reflectance.

Unfolding a Hidden Lagrangian Structure of a Class of Evolution Equations
Axioms, 2022 It is shown that a simple modification of the standard Lagrangian underlying the dynamics of Newtonian lattices enables one to infer the hidden Lagrangian structure of certain classes of first order in time evolution equations which lack the conventional

Invariants for Lagrangian tori
, 2004 We define an simple invariant of an embedded nullhomologous Lagrangian torus and use this invariant to show that many symplectic 4-manifolds have infinitely many pairwise symplectically inequivalent nullhomologous Lagrangian tori.

A Perspective on Interactive Theorem Provers in Physics
Advanced Science, EarlyView.Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics
