31P MRSI Coil Combination Using 23Na Sensitivity Information

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 1907-1920, April 2026.
ABSTRACT Purpose To optimally combine receive channels for 31P MRSI when the SNR is relatively low using sensitivity maps obtained from 23Na signals. Methods This study utilized a dedicated X‐nuclei 15‐channel head coil array capable of imaging both 23Na and 31P.

31P‐MRS of the Human Heart at 7 T With an Integrated Whole‐Body 31P Radiofrequency Transmit Coil

NMR in Biomedicine, Volume 39, Issue 4, April 2026.
We demonstrate the use of an integrated whole‐body phosphorus‐31 (31P) radiofrequency transmit coil for 31P‐MR spectroscopic imaging of the human heart at 7 T. Intersession measurement repeatability of the mid‐septal myocardial phosphocreatine (PCr) over adenosine triphosphate (ATP) concentration ratio in normal volunteers was 17.7%.

Spectroscopic Characterization and Electrocyclic Ring Opening of Parent 2‐Azetine

Journal of Physical Organic Chemistry, Volume 39, Issue 4, April 2026.
In this communication we report the observation of 2‐azetine from its N‐Boc‐protected precursor through thermal loss of isobutene and carbon dioxide and its subsequent ring opening to 1‐azabutadienes at elevated temperature. ABSTRACT (N‐Boc)‐protected 2‐azetine serves as a suitable precursor for the generation of parent 2‐azetine.

Machine Learning Based Prediction of Tropical Cyclone Rapid Intensification in the Western North Pacific: Importance of Data Augmentation and Loss Function

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract In this study, we developed a TabNet‐based machine learning model to predict tropical cyclone (TC) rapid intensification (RI) in the Western North Pacific. The most significant challenge in predicting RI is the severe class imbalance between rapid and non‐rapid intensification cases, typically 4.2:1 ratio based on 1977–2021 records.
