Pupil Plane Multiplexing for Vectorial Fourier Ptychography

Laser &Photonics Reviews, Volume 20, Issue 9, 6 May 2026.
This study proposes a cost‐effective, modality‐adaptive multichannel microscopy framework using pupil‐plane multiplexing. A custom pupil aperture at the Fourier plane encodes channel‐specific transfer functions with spectral or polarization filters, and model‐based reconstruction with channel‐dependent priors decodes them.

Hunga‐Tonga Volcano Plumbing System Inferred From Virtual Seismometer Approach

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract We present a surface wave tomography application based on event‐pair interferometry to investigate local (∼100 km) mid‐ocean crustal structures, with a particular focus on imaging a potential crustal solidified intrusive complex in a region lacking seismic stations.

Unraveling the Mystery of Melt Migration in Migmatites: From Channeling Instability to Pattern Formation

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Melt migration in partially molten rocks is commonly described by porous flow models controlled by the hydro‐mechanical compaction length, which effectively explains melt extraction at mid‐ocean ridges. However, this framework cannot account for the paradoxical accumulation of small melt fractions into rhythmic leucosome–melanosome bands in ...

Detection and Modeling of Co‐Seismic Ionospheric Disturbances Induced by the 2024 Mw 6.6 Deep‐Focus Earthquake in Brazil

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract On 20 January 2024, a deep‐focus earthquake (Mw 6.6, depth 607 km) struck near Tarauacá, Brazil, within the subducted South America Nazca Plate. Although it produced no surface damage, the event generated clear co‐seismic ionospheric disturbances (CSIDs) detectable in GNSS‐based Total Electron Content (TEC) data from the Brazilian RBMC network.

Critical point drying of brain tissue for X‐ray phase‐contrast imaging

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 759-768, May 2026.
X‐ray phase contrast tomography can efficiently image brain tissue at subcellular resolution. Critical point drying allows a gentle replacement of interstitial material by air, enhancing X‐ray phase contrast of the ultrastructural features.X‐ray phase‐contrast tomography can efficiently image brain tissue at subcellular resolution.

On the optimization of the geometric pattern for structured illumination based X‐ray phase contrast and dark‐field imaging: a simulation study and its experimental validation

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 806-817, May 2026.
Single‐mask phase contrast and dark‐field imaging methods offer the great advantage of being simple to implement, translating most of the complexity to the numerical side. In this work, we study the impact of the modulation topology on the image quality retrieved both on numerical simulation and experiments.Phase contrast and dark‐field imaging are ...
