Ferumoxytol‐Enhanced Myocardial T1 Tracking Using a Hybrid 2D/3D Steady‐State MRI Sequence Captures Cyclic Intramyocardial Blood Volume Dynamics

open access: yesNMR in Biomedicine, Volume 39, Issue 6, June 2026.
Cyclic changes in intramyocardial blood volume (iMBV) from systole to diastole can mark coronary disease without the need for vasodilator stress. We present a ferumoxytol‐enhanced MRI technique using a new continuous pulse sequence that effectively tracks cyclic myocardial T1 changes.

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 ...

Scattering from the pec flat strip by using the method of moments with sinc type basis functions

open access: yes, 2006
Using sinc methods is a very powerful technique in physics and mathematics. They give good accuracies and they're easily implemented. Method of Moments (MoM) is used to transform linear operator equations to linear algebraic equations such as matrix ...

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.
