Enhancing Dose Efficiency of Optimum Bright‐Field Scanning Transmission Electron Microscopy Using a Phase‐Shifted Electron Probe

open access: yesSmall Methods, Volume 10, Issue 11, 8 June 2026.
ABSTRACT Observing beam‐sensitive materials using scanning transmission electron microscopy (STEM) at low electron dose conditions is challenging due to the low signal‐to‐noise ratio (SNR) of images. In this study, we aimed to improve the SNR of optimum bright‐field (OBF) STEM by introducing phase shifts to the incident electron probe using lens ...

Error analyses of Sinc-collocation methods for exponential decay initial value problems

open access: yes
Nurmuhammad et al. developed the Sinc-Nystr\"{o}m methods for initial value problems in which the solutions exhibit exponential decay end behavior. In these methods, the Single-Exponential (SE) transformation or the Double-Exponential (DE) transformation

Standardized Frameworks for n‐Alkane Compound‐Specific Isotope Analysis: Assessments and Analytical Platform for Data Processing Workflows and Uncertainty Estimation

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Post‐acquisition processing of plant wax n‐alkane isotope data in compound‐specific isotope analysis (CSIA) remains variable and often lacks transparency. To improve inter‐laboratory comparability and data reliability, we present standardized, reproducible workflows for CSIA that address key challenges in drift correction, scale normalization,

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

open access: yesRadio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

Tubular Omega‐3 Fatty Acid Receptor FFAR4 Deficiency Aggravated Renal Aging and Chronic Kidney Disease

open access: yesAging Cell, Volume 25, Issue 6, June 2026.
This study illustrates that omega‐3 PUFAs with their receptor FFAR4 alleviate tubular senescence and fibrosis in aged and fibrotic kidneys. Furthermore, we indicate that tubular FFAR4 improves renal senescence via 15d‐PGJ2‐PPARγ‐Klotho signaling, and suppresses kidney fibrosis by senescent tubular cell‐driven fibroblast activation.
