Neuromelanin Contrast Optimization and Improved Visualization of the Substantia Nigra in a 3D Gradient‐Echo Sequence With Magnetization Transfer

open access: yesNMR in Biomedicine, Volume 38, Issue 9, September 2025.
The enhancement of the neuromelanin contrast based on low flip angles in a 3D gradient echo sequence with magnetization transfer improved the visualization of the neuromelanin‐rich region of the substantia nigra, as demonstrated by volumetric and contrast ratio analyses. Furthermore, in this study, the magnetization transfer pulse effects on the T1 and

Effects of physics beyond the standard model on the neutrino charge radius: an effective Lagrangian approach

open access: yes, 2008
In this work, we look for possible new physics effects on the electromagnetic charge and anapole form factors, $f_Q(q^2)$ and $f_A(q^2)$, for a massless Dirac neutrino, when these quantities are calculated in the context of an effective electroweak Yang ...

Triply-Periodic Smectics [PDF]

open access: yes, 2006
Twist-grain-boundary phases in smectics are the geometrical analogs of the Abrikosov flux lattice in superconductors. At large twist angles, the nonlinear elasticity is important in evaluating their energetics.

A fall into a pit, a gain in your wit: The Greensill's collapse

open access: yesRisk Management and Insurance Review, Volume 28, Issue 3, Page 382-397, Fall 2025.
Abstract The complexity of risk management arises from the diverse and interconnected risks that organizations face, requiring comprehensive strategies and tools to effectively identify, assess, mitigate, and monitor them. As a critical organizational function, risk management facilitates risk‐informed decision‐making that balances risk‐reward trade ...

Evaluation of Calcium Hypochlorite and Peroxyacetic Acid to Inactivate E. coli and Salmonella in Irrigation Water in Maryland

open access: yesJournal of Food Safety, Volume 45, Issue 3, June 2025.
ABSTRACT Addition of antimicrobials to water used for irrigation of fresh produce is recommended to reduce microbial food safety risks. However, there remains a need to validate the efficacy of antimicrobials in irrigation water using the microbial strains and methods recommended by the Environmental Protection Agency (EPA).

Magnetocaloric Effect Caused by Paramagnetic Austenite–Ferromagnetic Martensite Phase Transformation [PDF]

open access: yes, 2018
In the present work, the magnetization of Ni50Mn17.5Ga25Cu7.5 alloy undergoing the first-order phase transition from paramagnetic austenite to ferromagnetic martensite was measured to evaluate the magnetic-field-induced entropy change (MFIEC) and ...
