Motion‐ and Field‐Robust Mesoscopic Whole‐Brain T2*$$ {T}_2^{\ast } $$‐Weighted Imaging at 7 and 11.7 T Using Servo Navigation

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 5, Page 2658-2670, May 2026.
ABSTRACT Purpose To mitigate artifacts related to motion and field changes in high‐resolution T2*$$ {T}_2^{\ast } $$‐weighted human brain imaging using servo navigation at ultra‐high fields up to 11.7 T. Methods MR‐based servo navigators were integrated into a segmented 3D‐EPI sequence to allow for prospective correction of involuntary head motion and ...

Dosimetric comparison of TG‐43 formalism and HU‐based AcurosBV algorithms in HDR brachytherapy for head‐and‐neck superficial lesions with H.A.M. applicators

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.
Abstract Background TG‐43 formalism assumes homogeneous water media, potentially overlooking anatomical heterogeneities that affect dose accuracy. AcurosBV, a model‐based dose calculation algorithm, accounts for tissue and material heterogeneities. This study evaluates their dosimetric differences in high‐dose‐rate (HDR) brachytherapy using Harrison ...

Depositional and stratigraphic evolution of a Permian megalake system: Implications for seiche‐influenced models

open access: yesThe Depositional Record, Volume 12, Issue 2, April 2026.
During the Late Permian, the rise of the Gondwanides Belt trapped marine waters, giving birth to a vast megalake. This lake shifted between overfilled, balanced‐fill and underfilled stages that are recorded by high‐frequency accommodation changes, while meteorological seiches shaped the sedimentary dynamic and produced heterolithic beds.

Ultimate Intrinsic SNR in the Torso of Realistic Body Models

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 4, Page 2409-2419, April 2026.
ABSTRACT Purpose This work aims to investigate how the ultimate intrinsic signal‐to‐noise ratio (uiSNR) varies with increasing static magnetic field B0$$ {B}_0 $$ in the torso of realistic body models. Methods A dipole cloud was positioned around the realistic body model and randomly excited.

Trends in K‐12 science education research on students' interest, motivation and attitude towards science and technology: A systematic, reproductive and comparative review of 12 more years (2013–2024)

open access: yesReview of Education, Volume 14, Issue 1, April 2026.
Abstract This study presents a systematic, reproductive and comparative review of research on students' interest, motivation and attitude (I/M/A) towards science and technology (S&T) at K‐12 levels, covering the period 2013–2024. As a follow‐up to a previous systematic review (2000–2012), it describes and synthesizes findings from 170 peer‐reviewed ...
