On Determination Method for Resolution of Secondary Electron Images in Scanning Electron Microscopy

Advanced Science, Volume 13, Issue 44, 7 August 2026.
An idealized SEM, termed Rayleigh's microscope, is constructed by Monte Carlo simulation to represent imaging conditions that just satisfy the Rayleigh criterion. Based on this physically defined model, sharpness–resolution conversion curves are established and combined with the Rose criterion, enabling automated resolution evaluation from practical ...

Dynamic Single‐Binding Event Profiling With on‐Chip Microlenses for Wash‐Free Digital Biosensing

Advanced Science, Volume 13, Issue 46, 17 August 2026.
A microlens‐enhanced platform enables real‐time tracking and digital counting of single‐binding events using conventional bright‐field microscopy. Amplified scattering signals from gold nanoparticle labels and kinetic signature analysis allow wash‐free discrimination between specific and nonspecific interactions, while providing kinetic and mechanistic

Geometry‐Dependent Surface Lambertian‐Equivalent Reflectivity (GLER) Climatology for the TEMPO Mission

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract We describe a Geometry‐dependent surface Lambertian‐Equivalent Reflectivity (GLER) climatology developed to support operational retrievals for the Tropospheric Emissions: Monitoring of Pollution (TEMPO) mission. This data set provides monthly and hourly surface reflectance for snow‐free land, snow‐covered land, and oceanic regions.

Saturation Effects in Narrowband Resonance Lidar Measurements, Part 1: Theoretical Consideration of Sodium, Iron, and Helium Lidar Systems

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Atmospheric resonance lidars targeting metallic species in the mesosphere and lower thermosphere have yielded insights into the dynamics of the middle and upper atmosphere for over 50 years. Recently, the technique has been extended to the metastable helium layer, which reaches up to 1,000 km or above.

Investigations of Backscattering Effects in Optical Fibers and Their Influences on the Link Monitoring

IEEE Photonics Journal, 2017
In this paper, first, we employed the coupled-mode theory to investigate the backscattering power characteristics of Rayleigh backscattering (RB) and stimulated Brillouin scattering (SBS) both synchronously and precisely. We discovered how the RB and SBS
