Brain Pulsation Imaging Using Non‐Balanced Steady‐State Free Precession With 3D‐EPI Readout

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 3, Page 1606-1618, March 2026.
ABSTRACT Purpose To present a new, fast MR imaging method for visualization and quantification of pulsatile displacement in brain tissue and fluid. Methods The natural phase‐contrast of non‐balanced steady‐state free precession combined with careful tuning of the intrinsic spoiler gradients is harnessed to measure displacement along specific physical ...

Mechanisms for the Oxonolysis of Ethene and Propene: Reliability of Quantum Chemical Predictions [PDF]

open access: yes, 2003
Reactions of ozone with ethene and propene leading to primary ozonide (concerted and stepwise ozonolysis) or epoxide and singlet molecular oxygen (partial ozonolysis) are studied theoretically.

Development and Validation of an HPLC–UV Method for the Quantification of Cefepime in Human Plasma for Routine Clinical Monitoring

open access: yesSEPARATION SCIENCE PLUS, Volume 9, Issue 3, March 2026.
ABSTRACT Cefepime, a broad‐spectrum fourth‐generation cephalosporin, is widely used to treat nosocomial infections. Dependence upon renal elimination makes its pharmacokinetics highly susceptible to changes in renal function, which are common in critically ill patients.

The Evolution of a Polar Cap Patch Into a Blob in the Nightside Ionosphere: Direct Observations of Multiple Blob Formation Mechanisms Acting Simultaneously on the Same Plasma

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract A polar cap patch was observed to exit the polar cap to become a blob as it entered the auroral oval on the nightside of the Earth under moderately quiet geomagnetic conditions (Kp = 3−). Auroral particle precipitation led to an increase in the electron density of the blob.

First Coincident Radar and Optical Observations of a Meteor Radio Afterglow

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract It has been hypothesized that Meteor Radio Afterglows (MRAs) occur due to resonant transition radiation (RTR) where suprathermal electrons emit as they pass through electron density inhomogeneities in a turbulent plasma. Meteor trails are thought to produce suprathermal electrons through anion oxidation, which can be identified through meteor ...

Radio Propagation in Railway Corridors Through Dense Forests–Measurement and Modeling at 460 MHz

open access: yesRadio Science, Volume 61, Issue 3, March 2026.
Abstract Current train signaling systems are being replaced by advanced systems like Communications‐Based Train Control, European Rail Traffic Management System, and Positive Train Control, which rely on radio networks. However, railways operating in dense forest environments face unique challenges for wireless systems due to high levels of signal ...
