Assessing Co‐Located NISAR and Sentinel‐1 Observations for Atmospheric Characterization

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Tropospheric delay remains one of the largest sources of uncertainty in repeat‐pass Interferometric Synthetic Aperture Radar (InSAR) measurements, while accurate three‐dimensional deformation retrieval continues to be limited by the geometry of current spaceborne SAR systems.

Beating the Standard Quantum Limit With Single‐Photon‐Added Coherent States

Advanced Physics Research, Volume 5, Issue 10, October 2026.
The standard quantum limit (SQL) defines how quantum fluctuations of light constrain measurement precision. Here, we show that injecting a single‐photon‐added coherent state and a weak coherent state in the input ports of a Mach–Zehnder interferometer reduces phase uncertainty below the SQL.

TrustSpec: Simulation‐Grounded Physics‐Driven Spectral Inversion With Uncertainty Quantification for SiC Epitaxial Thickness Metrology

Engineering Reports, Volume 8, Issue 10, October 2026.
TrustSpec reuses a single spectral digital twin both to train a deep ensemble and to verify each prediction via analysis‐by‐synthesis. A two‐channel trust plane automatically releases, reviews, or rejects every SiC epitaxial thickness reading, achieving 0.110 μm mean error with full out‐of‐distribution rejection in simulation.

New IOL formula using anterior segment three-dimensional optical coherence tomography.

PLoS ONE, 2020
This retrospective study was aimed to compare prediction errors from various combinations of biometric data generated using optical coherence tomography (OCT) and develop a new intraocular lens (IOL) formula using biometric data.

Geomorphic Imprints of Coseismic Uplift: Knickpoints and Landslides on the Noto Peninsula, Japan

Earth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.
River knickpoints and slow‐moving landslides show complementary spatial relationships with the vertical and horizontal deformation fields of the 2024 Mw 7.5 Noto Peninsula earthquake. Together, their distributions provide geomorphic information for evaluating cumulative landscape adjustment to repeated coseismic uplift at a regional scale.

Nanosecond, Nanometer Movies of MEMS/NEMS Dynamics in a Standard SEM Using Time‐Tagged Secondary Electrons

Small Methods, Volume 10, Issue 19, 7 October 2026.
For the observation of micromechanical devices, a fast imaging technique with high temporal resolution is needed. Here, we demonstrate that a standard scanning electron microscope can be converted into a time‐resolving instrument using a fast detector and a time‐to‐digital converter.

Partially coherent nano-focused x-ray radiation characterized by Talbot interferometry

Optics Express, 2011
We have studied the spatial coherence properties of a nano-focused x-ray beam by grating (Talbot) interferometry in projection geometry. The beam is focused by a fixed curvature mirror system optimized for high flux density under conditions of partial coherence.

Estimation of Mesoscale Momentum Flux Frequency Spectra in the Mesosphere and Lower Thermosphere Using Multistatic Specular Meteor Radar Wind Fields

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract A spectrally resolved observational methodology is introduced to estimate mesoscale momentum flux frequency spectra in the mesosphere and lower thermosphere (MLT). The method is applied to four‐dimensional wind fields reconstructed with the physics‐informed neural network approach called the Hydrodynamic Point‐wise Environment Reconstructor ...
