Background Instability of Quintessence Model in Light of Entropy and Distance Conjecture

Fortschritte der Physik, Volume 74, Issue 6, June 2026.
ABSTRACT We apply the covariant entropy bound argument supporting the de Sitter swampland conjecture to the quintessence model, to find out the condition for the background to be unstable. More concretely, the background is unstable when the matter entropy given by the species number of the effective field theory increases more rapidly than the ...

Reconfigurable Nanogap SERS for Multiscale Molecular Sensing on Curved Surfaces

Small, Volume 22, Issue 35, 23 June 2026.
Reconfigurable Au‐coated SMP nanocomposites enable adaptive SERS through reversible tuning of Au─Au nanogaps. Embedded AgNPs serve as photothermal triggers and reinforcements. Wide gaps facilitate macromolecule detection, while narrowed gaps enhance small‐molecule signals for reliable multiscale sensing on curved surfaces.

Precise 3D Tracking of Highly Non‐Planar Eukaryotic Flagellar Beating Patterns Using Digital Holographic Microscopy

Small Methods, Volume 10, Issue 12, 23 June 2026.
The 3D beating dynamics of eukaryotic flagella drive motility, sensory functions, and resource acquisition, yet highly non‐planar beating patterns remain poorly characterized. Based on Digital Holographic Microscopy, holoV3C enables label‐free 3D reconstruction of such complex dynamics with 53 nm axial resolution, demonstrated on mouse sperm and ...

Computational methods for automated center determination in electron diffraction patterns

Journal of Applied Crystallography, Volume 59, Issue 3, Page 845-857, June 2026.
This study evaluates and compares automated methods for center detection in 2D diffractograms. The methods have been implemented in EDIFF, an open‐source user‐friendly Python package for the processing of electron diffraction patterns.Accurate center detection in electron diffraction patterns is critical for all subsequent processing of experimental ...
