Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 542-547, August 2026.ABSTRACT Purpose This study investigates the effect of VAPOR water suppression and metabolite cycling on metabolite quantification and macromolecules in proton magnetic resonance spectroscopy. Methods Single‐voxel semi‐LASER spectra (TR/TE = 3000/28 ms) and metabolite‐nulled spectra (macromolecules) were acquired in five healthy subjects in the ...

Estimation precision of degree of polarization in the presence of signal-dependent and additive Poisson noises [PDF]
Journal of the European Optical Society-Rapid Publications, 2008 We address precision of estimation of the degree of polarization (DOP) from the orthogonal state contrast image (OSCI) in the presence of both signal-dependent Poisson noise due to useful signal, and additive Poisson noise due to dark current and / or ...

MR Spectroscopy Without Water Suppression Using the Gradient Impulse Response Function
Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 530-541, August 2026.ABSTRACT PurposeNon‐water‐suppressed proton spectroscopy, 1H‐MRS, is desirable, as retaining the strong water resonance can facilitate automated online data corrections, internal concentration referencing, and monitoring of line narrowing effects in functional MRS. Removal of the water suppression module can also mitigate magnetization transfer effects

CPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 8, August 2026.ABSTRACT Aging is a systems‐level process linking metabolic dysfunction, inflammation, impaired repair, frailty, and multimorbidity, whereas existing pharmacological strategies usually optimize disease‐specific endpoints such as weight loss or HbA1c rather than aging‐related trajectories. We developed an SBML‐compliant quantitative systems pharmacology

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1192-1199, August 2026.We demonstrate a Fisher‐information‐based strategy for optimizing the solid substrate structure in polarized neutron reflectometry experiments on soft‐matter samples. The approach identifies magnetic reference layer designs that improve experimentally accessible information and provides a general framework for more efficient reflectometry experiment ...

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3
Annals of Clinical and Translational Neurology, Volume 13, Issue 7, Page 1452-1466, July 2026.ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...
