Magnusian: relating the eikonal phase, the on-shell action, and the scattering generator

Journal of High Energy Physics
Two fundamentally distinct types of quantities are both called “eikonal” in present amplitudes literature. The unitarity of the S-matrix ensures it can be written as the exponential of a Hermitian operator.

Jet Drift in Heavy Ion Collisions [PDF]

EPJ Web of Conferences
We introduce a sub-eikonal anisotropic contribution to jetbroadening, “jet drift”, that couples to the flow of the medium, showing that this effect results in a deflection of hard partons, and thus jets, in the direction of the medium flow.

The eikonal approach to gravitational scattering and radiation at O $$ \mathcal{O} $$ (G 3)

Journal of High Energy Physics, 2021
Using N $$ \mathcal{N} $$ = 8 supergravity as a theoretical laboratory, we extract the 3PM gravitational eikonal for two colliding massive scalars from the classical limit of the corresponding elastic two-loop amplitude.

CGC beyond eikonal accuracy: finite width target effects

EPJ Web of Conferences, 2016
We present a method to systematically include the corrections to the eikonal approximation that are associated with the finite width of the target. The retarded gluon propagator in background field is calculated at next-to-next-to-eikonal (NNE) accuracy ...

Longer action potential duration in the Purkinje network than in the ventricular myocardium delays retrograde activation of the human His‐Purkinje system

The Journal of Physiology, EarlyView.
Abstract figure legend Activation time (AT) maps from right ventricular apical pacing in a human ventricles model with longer action potential duration in the His‐Purkinje system (HPS) than in the myocardium (MYO). For pacing with a long S1S2 coupling interval (CI), the AT from the myocardial pacing site to the first AT of the HPS (ATMYO) is longer ...

Ultra‐Confinement of Polaritons in Single Atomic Layer Ag Photonic Quantum Dots

Advanced Materials, Volume 38, Issue 36, 26 June 2026.
Strong confinement of surface phonon polaritons of silicon carbide was achieved in photonic quantum dots fabricated from van der Waals heterostructure of epitaxial graphene over single‐atomic layer silver. Scattering‐type scanning near‐field optical microscopy combined with an analytical approach, developed to reveal local propagation constants with ...

SKOOTS: Skeleton‐Oriented Object Segmentation for Mitochondria in High‐Resolution Cochlear EM Datasets

Advanced Science, Volume 13, Issue 32, 9 June 2026.
Skeleton‐oriented object segmentation (SKOOTS) introduces a new strategy for 3D mitochondrial instance segmentation by predicting explicit skeletons rather than relying on boundary cues. This approach enables robust analysis of densely packed organelles in large FIB‐SEM datasets.

Quantization conditions and the double copy

Journal of High Energy Physics, 2022
We formulate Wilson loop observables as products of eikonal Wilson lines given in terms of on-shell scattering amplitudes. We derive the eikonal phases for dyons in both gauge theory and gravity, which we use to derive the Dirac-Schwinger-Zwanziger ...

Automated Centerline Extraction From Meshed Vascular Models

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 6, June 2026.
A method to extract centerlines from image‐based vascular meshes is presented, which automatically identifies vascular endpoints and traces centerlines by solving Eikonal equations. Compared to a widely used method, the proposed approach requires less user interaction and demonstrates better robustness on models that contain segmentation artifacts from
