Stokes‐Based 3D Polarimetric Analysis of Dipolar Near‐Fields

Advanced Photonics Research, Volume 7, Issue 8, August 2026.
Characterizing the near‐field polarization of dipolar emitters is of growing importance in nanophotonics, since many subwavelength systems resemble their emission. In this work, we apply the 3D Stokes formalism and its intrinsic reference frame to analyze the polarization properties of various dipole emitters from the near‐ to the far‐field, allowing a

Residue curve maps of 4-component systems. Poincare index determination for 4-component azeotrope

Тонкие химические технологии, 2011
A method of Poincare index determination for a singular point corresponding to a 4-component azeotrope is proposed. The method is based on the equation of azeotropic relationship.

Field‐Programable Dynamics in a Soft Magnetic Actuator Enabling True Random Number Generation and Reservoir Computing

Advanced Intelligent Systems, Volume 8, Issue 8, August 2026.
Complex dynamics, often avoided in electromechanical design, can enhance soft robotics. We develop durable magnetic soft actuators operating in tunable dynamic regimes, enabling random number generation, stochastic computing, and time‐series prediction.

Gravitational Radiation From Binary Systems With Time Varying Masses

Annalen der Physik, Volume 538, Issue 8, August 2026.
We extend the standard approach pioneered in the works by Peters and Mathews to include the mass loss processes of the binary components, by obtaining the variations due to gravitational radiation of the main physical parameters. As an application of our results we consider gravitational radiation emission in binary magnetar systems.

Succinct representation of the Poincare map for periodically driven differential equations [PDF]

, 2019
A differential equation, periodically driven with period T, defines the time evolution of the solution, a state vector x(t). The Poincaré, or time one, map is a function that relates to x(t + T)to x(t).

A Comprehensive and Critical Evaluation of Autonomic Nervous System Impairment in Patients with Wilson Disease: A Cross‐Sectional Study

Brain and Behavior, Volume 16, Issue 8, August 2026.
ABSTRACT Background Wilson's disease (WD) is an autosomal recessive disorder of copper metabolism with heterogeneous hepatic and neurological manifestations. Autonomic nervous system (ANS) involvement in WD is poorly recognized and remains inadequately studied, despite its potential to cause significant morbidity if unrecognized.

Shape differentiation for Poincaré maps of harmonic fields in toroidal domains [PDF]

International audienceIn this article, we study Poincaré maps of harmonic fields in toroidal domains using a shape variational approach. Given a bounded domain of $\mathbb{R}^3$, we define its harmonic fields as the set of magnetic fields which are curl ...

Controlling Collective Quasiparticle Dynamics Beyond Decoherence in Topological Interfaces

Laser &Photonics Reviews, Volume 20, Issue 16, 21 August 2026.
Gold nanoparticles placed above a deformed honeycomb plasmonic crystal couple to a chiral topological interface mode. The pseudospin‐split bands ψ+/ ψ− encode spin‐momentum locking, so emitters radiate directionally along the domain wall and share a common phase.

Kuga–Satake Construction on Families of K3 Surfaces of Picard Rank 14

Mathematische Nachrichten, Volume 299, Issue 8, Page 1894-1916, August 2026.
ABSTRACT The isometry between the type IV6 and the type II4 hermitian symmetric domains suggests a possible relation between suitable moduli spaces of K3 surfaces of Picard rank 14 and of polarized abelian 8‐folds with totally definite quaternion multiplication. We show how this isometry induces a geometrically meaningful map between such moduli spaces
