Overcoming Computational Bottlenecks in Quantum Hydrodynamics: A Volume‐Based Integral Formalism for Spherical Nanoparticles

open access: yesNanophotonics, Volume 15, Issue 13, 13 July 2026.
Numerical modeling of mesoscopic material response models that capture the quantum dynamics of electrons does not have to come with discouraging computational bottlenecks. The main message is that through a shift in perspective in modeling toward integral equation methods and exploiting symmetry‐based arguments, it is possible to capture complicated ...

Extended symmetrical classical electrodynamics [PDF]

open access: yesPhysical Review E, 2008
In the present article, we discuss a modification of classical electrodynamics in which ``ordinary'' point charges are absent. The modified equations contain additional terms describing the induced charges and currents. The densities of the induced charges and currents depend on the vector k and the vectors of the electromagnetic field E and B.

Femtosecond‐Laser Mould Texturing Enables Tunable Biointerfaces in COC Microfluidics

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 13, 7 July 2026.
Femtosecond‐laser texturing of injection‐mould inserts enables scalable engineering of biointerfaces in cyclic olefin copolymer microfluidics. Replicated micro‐ and nano‐topographies modulate surface roughness and wettability, leading to texture‐dependent protein adsorption and cell adhesion without chemical post‐processing.

Chemical Shift Separated and Compensated Ultra‐Short Echo‐Time Imaging

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 121-133, July 2026.
ABSTRACT Purpose To develop a modified binomial excitation scheme for ultra‐short echo‐time (UTE) imaging that allows for the separation of water and fat signals and the correction of chemical shift artifacts. Methods Theoretical derivation and numerical Bloch simulations were performed for a modified water‐excitation binomial pulse scheme to calculate

Local Selective Realism: shifting from Classical to Quantum Electrodynamics [PDF]

open access: yes, 2020
This article elaborates local selective realism in view of the shifting from classical to quantum electrodynamics. After some introductory remarks, we critically address what we call global selective realism, hence setting forth the background for ...

A Dialogue on Revolutions and Revolutionaries in Science: A Perspective From Quantum Mechanics

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT We discuss the notions of scientific revolutions and revolutionaries in the context of the Relativity Revolution and of the First, Second, and Third Quantum Revolutions. We conclude that at the core of the question of what qualifies as a revolution and revolutionary is an assessment of the gradients of knowledge accumulation over time, both at
