Bertrand’s theorem and the double copy of relativistic field theories
Journal of High Energy PhysicsWhich relativistic field theories give rise to Kepler dynamics in the two-body problem? We consider a class of Hamiltonians that is the unique relativistic extension of the Kepler problem preserving its so(4) algebra, and have orbits related through time

ChemBioChem, Volume 27, Issue 7, 14 April 2026.We present a versatile approach to uniform hybrid microgels containing magnetite nanoparticles (MNPs). Methylcellulose stabilizes MNPs in pre‐hydrogel suspensions, enabling microfluidic processing. Functionalization with biotin yields an experimental platform for enzyme immobilization, shown by immobilizing streptavidin‐horseradish peroxidase (HRP) and

Synthesis, Structure, and Thin Film Optical Properties of a Chiral Benzothiazole‐Derived Squaraine
ChemPhysChem, Volume 27, Issue 7, 14 April 2026.Solution‐processed thin films can be sensitive to the choice of solvent and thermal annealing, which we explore for a chiral benzothiazole squaraine. We observe peculiarly shaped excitonic circular dichroism in uniaxially anisotropic thin films, in which the presumed Davydov bands are spatially distributed exclusively into in‐plane (UDC) and out‐of ...

Capsular Bag Performance of a Novel Hydrophobic Single-Piece Intraocular Lens
Ophthalmology and TherapyIntroduction We conducted an evaluation of capsular bag performance of the Clareon CNA0T0 intraocular lens (IOL), focusing on postoperative anterior chamber depth (ACD), IOL tilt, and IOL decentration.

A Search for Temporal Atmospheric Variability of Kepler Hot Jupiters
The Astronomical JournalWe perform a systematic search for atmospheric variability in short-period gas-giant planets (hot Jupiters) observed by the Kepler mission, by looking for temporal variability of their secondary eclipse depths.

Ages of “Singles” versus “Multis”: Predictions for Dynamical Sculpting over Gyr in the Kepler Sample
The Astronomical JournalThe sample of host stars with multiple transiting planets has illuminated the orbital architectures of exoplanetary systems. These architectures may be shaped mostly by formation conditions, be continually sculpted by ongoing dynamical processes, or both.

Accounting for Transit Timing Detectability: Biases in Planetary Radius and Orbital Period
The Astronomical JournalTransit Timing Variations (TTVs) are deviations from the time an observer would expect to see an exoplanet transit its host star. In multiplanetary systems, significant TTVs may indicate the presence of another body in the system gravitationally ...

The Gap–Giant Association: Are Planets Hiding in the Gaps?
The Astrophysical JournalA handful of stars are known to host both an inner system of multiple transiting planets and an outer giant planet. These systems all feature a prominent gap between the orbits of two of the transiting planets, distinguishing them from typical ...
