Observation of Linear and Nonlinear Light Trapping on Topological Dislocations

Laser &Photonics Reviews, Volume 20, Issue 8, 17 April 2026.
Topological dislocations are global lattice defects found in various systems ranging from crystals to photonic lattices. This work reports the first observation at optical frequencies of linear modes with tunable localization bound to edge dislocations and their nonlinear counterparts ‐ dislocation solitons. These results reveal an intriguing interplay

Direct optimization of the probability of lesion origin in proton treatment planning for low‐grade glioma patients

Medical Physics, Volume 53, Issue 4, April 2026.
Abstract Background In proton therapy of low‐grade glioma (LGG) patients, contrast‐enhancing brain lesions (CEBLs) on magnetic resonance imaging are considered predictive of late radiation‐induced lesions. From the observation that CEBLs tend to concentrate in regions of increased dose‐averaged linear energy transfer (LETd) and proximal to the ...

Dynamic Transitions for Fast Joint Acquisition and Reconstruction of CEST‐Rex$$ {R}_{ex} $$ and T1$$ {T}_1 $$

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2153-2168, April 2026.
ABSTRACT Purpose This work proposes a method for the simultaneous estimation of the exchange‐dependent relaxation rate Rex$$ {R}_{ex} $$ and the longitudinal relaxation time T1$$ {T}_1 $$ from a single acquisition. Methods A novel acquisition scheme was developed that combines CEST saturation with an inversion pulse and a Look‐Locker readout to capture

Large Deformation Pile‐soil Interaction Under Lateral Vehicle Impact Using Hybrid SPH+FEM and EFG+FEM Models

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 5, Page 2648-2669, 10 April 2026.
ABSTRACT This study presents large deformation computational methods to simulate lateral vehicular impacts on steel piles in granular soil. Soil‐mounted longitudinal barrier systems rely on energy dissipation in both the piles and the surrounding soil to safely redirect errant vehicles, so dynamic pile‐soil interaction is important for design ...

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Quantum Dust Cores of Black Holes and Their Quasi‐Normal Modes

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
We investigate the quasi‐normal mode spectrum of a gravitationally collapsed ball of dust, considering both a linear and a refined parabolic effective mass function for the quantum core. Furthermore, we account for the quantum leakage of dust particles outside the horizon.
