Evaluation of Partial Volume Correction Techniques for Sodium MRI of the Achilles Tendon
Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2180-2193, April 2026.ABSTRACT Purpose To evaluate partial volume correction (PVC) techniques for sodium MRI of the Achilles tendon in situ and in vivo. Methods Five PVC methods were evaluated including a volume ratio of the proton and sodium segmentations (PSSR), a modified least trimmed square (3D‐mLTS) linear regression, a geometric transfer matrix (GTM) approach, a ...

The Effect of Melatonin on Behavioral, Molecular, and Histopathological Changes in Cuprizone Model of Demyelination [PDF]
, 2016 Multiple sclerosis (MS) is an autoimmune, demyelinating disease of the central nervous system. The protective effects of melatonin (MLT) on various neurodegenerative diseases, including MS, have been suggested.

People and Nature, Volume 8, Issue 4, Page 935-944, April 2026.Abstract For many people around the world, especially in Indigenous communities, seasonal changes affect the availability and desirability of different types of food. Assessing the relationship between seasonality, sociocultural preferences and hunting patterns is vital for understanding how these populations harness seasonal food production dynamics ...

Universal Time Influence on Stormtime Magnetosphere Ionosphere Coupling
AGU Advances, Volume 7, Issue 2, April 2026.Abstract The offset between Earth's magnetic and rotational axes introduces a diurnal dependence in the high‐latitude EUV exposure of the northern hemisphere (NH) and southern hemisphere (SH). This variation raises the question: Does the Universal Time (UT) of geomagnetic storm onset impact its geospace consequences?

Mechanism for the formation of the high-altitude stagnant cusp: Cluster and SuperDARN observations [PDF]
, 2006 On 16 March 2002, Cluster moved from nightside to dayside, across the high-altitude northern cusp during an extended period of relatively steady positive IMF BY and BZ. Combined Cluster and SuperDARN data imply the existence of two reconnection sites: in

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.Abstract Earth's magnetotail and its plasma sheet are highly dynamic, influenced by both the solar wind and the inner magnetosphere. Periodically, energy is explosively released in the magnetotail during substorms. However, the extent to which electrons are accelerated in the magnetotail remains an open question, with recent observations revealing ...

Imprint of the Quasi‐Biennial Oscillation on the Ionosphere and Thermosphere
Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.Abstract The Quasi‐Biennial Oscillation (QBO) is a dominant mode of stratospheric variability and is known to modulate the variability of the ionosphere‐thermosphere (IT) system. However, the extent of its influence on the ionosphere‐thermosphere system remains uncertain due to weak signals and confounding with similar periodicities in solar flux.
