Enhancement of Optical Spin-Orbit Coupling in Anisotropic ENZ Metamaterials
IEEE Photonics Journal, 2023 Vector vortex beams which possess complex intensity and polarisation patterns, and phase or polarisation singularities are important in a variety of applications ranging from high resolution imaging and data transmission to nonlinear optics and quantum ...

The Local Learning Coefficient: A Singularity-Aware Complexity Measure
, 2023 The Local Learning Coefficient (LLC) is introduced as a novel complexity measure for deep neural networks (DNNs). Recognizing the limitations of traditional complexity measures, the LLC leverages Singular Learning Theory (SLT), which has long recognized the significance of singularities in the loss landscape geometry.

Company welfare in modern Argentine railways: characteristics and challenges (1890-1920)
Revista Mundos do Trabalho, 2021 This article explores company welfare programs in the railways in modern Argentina from the 1890s to the 1920s. It concentrates on the singularities of these companies' strategies, considering that the local society was shaped by a process of mass ...

A universal form of localized complex potentials with spectral singularities
New Journal of Physics, 2020 Abstract We establish necessary and sufficient conditions for localized complex potentials in the Schrödinger equation to enable spectral singularities (SSs) and show that such potentials have the universal form U (

Multi-Fractality, Universality and Singularity in Turbulence
Fractal and Fractional, 2022 In most geophysical flows, vortices (or eddies) of all sizes are observed. In 1941, Kolmogorov devised a theory to describe the hierarchical organization of such vortices via a homogeneous self-similar process.

Local invariants of singular surfaces in an almost complex four-manifold [PDF]
Annals of Global Analysis and Geometry, 1993 Let \(f: S^2\to (M^4, J)\) be a generic mapping, that is, \(f\) is a finite cover of an almost everywhere immersion (except for a finite number of points) which has only finite complex points. To such a mapping \(f\) the authors assign local invariants \(i(x)\) and \(m(x)\) at every point \(x\in f (S^2)\). The invariant \(i(x)\) is defined as the local

Noncommutative resolutions of ADE fibered Calabi-Yau threefolds [PDF]
, 2010 In this paper we construct noncommutative resolutions of a certain class of Calabi-Yau threefolds studied by F. Cachazo, S. Katz and C. Vafa. The threefolds under consideration are fibered over a complex plane with the fibers being deformed Kleinian ...

Deformations of functions and F-manifolds [PDF]
, 2004 We study deformations of functions on isolated singularities. A unified proof of the equality of Milnor and Tjurina numbers for functions on isolated complete intersections singularities and space curves is given.
