A novel semi-fragile forensic watermarking scheme for remote sensing images [PDF]

open access: yes, 2011
Peer-reviewedA semi-fragile watermarking scheme for multiple band images is presented. We propose to embed a mark into remote sensing images applying a tree structured vector quantization approach to the pixel signatures, instead of processing each band ...

Transition Metal Dichalcogenide Multijunction Solar Cells Toward the Multicolor Limit

open access: yesSolar RRL, Volume 10, Issue 13, 15 July 2026.
A thermodynamic design framework reveals how transfer‐printable TMD multijunction solar cells approach the multicolor limit. Within the 1.0–2.1 eV TMD bandgap window, a five‐junction ladder nears the efficiency plateau, while radiative efficiency, luminescent coupling, excitonic absorption, and bottom‐cell stability set the practical headroom for van ...

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology

open access: yesAdvanced Engineering Materials, Volume 28, Issue 13, 8 July 2026.
We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Frequency‐Dependent Acoustic Reflection Coefficients of Flat Ground Assessed Using the Sonic Boom From the OSIRIS‐Rex Sample Return Capsule Recorded on Free Flying Balloons

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Low frequency sound can travel great distances in planetary atmospheres. When these waves reflect off the air/ground interface, energy may be absorbed or transferred to mechanical waves in the subsurface. This study describes the direct and reflected acoustic wave generated by the re‐entry of the OSIRIS‐REx Sample Return Capsule captured on a ...

Strong Mode Coupling and Maximum Directional Absorption in Reciprocal Bianisotropic Metasurfaces

open access: yesNanophotonics, Volume 15, Issue 12, 25 June 2026.
Symmetry breaking in q‐BIC dielectric metasurfaces enables strong electromagnetic coupling between electric and magnetic modes, leading to their hybridization and Rabi‐like splitting. This mechanism produces pronounced reciprocal bianisotropy and dual‐band asymmetric absorption under opposite illumination directions, offering a compact framework for ...

Magnetically Reconfigurable Mode Strong Coupling Toward Tunable Nanophotonic Sensing Devices

open access: yesNanophotonics, Volume 15, Issue 12, 25 June 2026.
A magnetically reconfigurable metasurface realizes tunable strong coupling between structural and magneto‐structurally induced q‐BIC resonances without changing device geometry. The resulting hybrid branches enable high‐sensitivity refractive‐index sensing with noncontact active control, large figure of merit, and multiple resonance observables ...
