Development of an adjustable dynamic phantom for testing deviceless motion correction algorithm in PET

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Respiratory motion during PET Imaging leads to blurring, volumetric overestimation, and reduced quantitative accuracy. Deviceless motion correction algorithms (MCA) such as OncoFreeze (OF) by Siemens Healthineers (Forchheim, Germany) extract respiratory waveforms from list‐mode data but require validation that cannot be obtained in ...

Water and Gas Exchange Responses of Five Related Blueberry Species (Ericaceae spp.) to the Dry Season in the High‐Andean Forest of the Colombian Eastern Cordillera

Plant-Environment Interactions, Volume 7, Issue 4, August 2026.
ABSTRACT Vaccinium, Cavendishia, and Macleania are typical genera of blueberries from the Ericaceae belt, a narrow ecosystem that connects the high Andean forest and páramo, where fragmentation makes the species more vulnerable to climate change. To answer the question of whether five related blueberry species could physiologically behave similarly in ...

Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.

MMS Observations of Multi‐Species Wave‐Particle Interactions and Rapid Foreshock Evolution

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The ion foreshock is the region upstream of Earth's bow shock where magnetic field lines connect to the quasi‐parallel shock surface. Within this region, there exist a variety of backstreaming ion populations from the shock ramp that can generate ultra‐low frequency (ULF) waves through wave‐particle interactions. In this work, we use data from

Excitation of Large Amplitude Compressional ULF Waves in the Magnetosphere by Solar Wind Pressure Spikes and IMF Southward Turning

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We present a case study of large amplitude, compressional Pc5 waves observed by GOES 13 and 15 at geosynchronous orbit near noon. These waves were excited near the arrival time of two consecutive solar wind dynamic pressure spikes at the magnetopause, the second of which was associated with a large and rapid southward turning of the ...
