Supercritical Angle Fluorescence and Raman Techniques in Biophotonics

Laser &Photonics Reviews, Volume 20, Issue 15, 7 August 2026.
Supercritical angle fluorescence (SAF) microscopy and supercritical angle Raman (SAR) spectroscopy have emerged as powerful tools in the field of biophotonics, enabling high‐resolution imaging and spectroscopy of biological specimens near interfaces. This review article provides a comprehensive overview of the principles, techniques, applications, and ...

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.

Improving Geomagnetic Perturbation Forecasts in the Southern Hemisphere via Kernel‐Based Encoding of Mirror Symmetry

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Accurate forecasting of geomagnetic perturbations is essential for assessing space weather risk of geomagnetic activities. Thanks to decades of magnetometer observations from world‐wide distributed networks and upstream solar wind observations at L1, data‐driven modeling of global geomagnetic perturbations has become increasingly feasible ...

Stochastic electrodynamics and the interpretation of quantum theory [PDF]

, 2020
I propose that quantum mechanics is a stochastic theory and quantum phenomena derive from the existence of real vacuum stochastic fields filling space.

Falsifying cosmological models based on a non-linear electrodynamics

European Physical Journal C: Particles and Fields, 2018
Recently, the nonlinear electrodynamics (NED) has been gaining attention to generate primordial magnetic fields in the Universe and also to resolve singularity problems. Moreover, recent works have shown the crucial role of the NED on the inflation. This

TRACERS Small‐Scale Field‐Aligned Currents and Intense GPS Amplitude and Phase Scintillations in the Nightside Auroral Region

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We present conjugate observations of ionospheric small‐scale magnetic perturbations (dB) $(dB)$ and GPS scintillations from the Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) and the Canadian High Arctic Ionospheric Network (CHAIN) during a storm‐time substorm on 9 August 2025 in the nightside auroral region ...

Femtosecond‐Laser Mould Texturing Enables Tunable Biointerfaces in COC Microfluidics

Advanced 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.

Duality between the Deconfined Quantum-Critical Point and the Bosonic Topological Transition

Physical Review X, 2017
Recently, significant progress has been made in (2+1)-dimensional conformal field theories without supersymmetry. In particular, it was realized that different Lagrangians may be related by hidden dualities; i.e., seemingly different field theories may ...

Localizing Root Causes of Incipient Failures of Distribution Oil‐Immersed Transformer Using a Distinctive Dynamic Multi‐Scale Attention CNN‐LSTM Algorithm via Composite Multiple Data Integration for Transformer Predictive Maintenance

Engineering Reports, Volume 8, Issue 7, July 2026.
The root cause localization framework in Figure 1 is an extension of anomaly detection where further insights on incipient transformer faults or failures are analyzed. The framework aims to provide a complete diagnostic solution to detected anomalies to ensure efficient transformer maintenance while minimizing downtimes and allowing for optimal use of ...
