Residual Chemical Shift Anisotropies in the Structure Determination of Small Molecules

open access: yesMagnetic Resonance in Chemistry, EarlyView.
Plasma neutrophil elastase(ELANE) was markedly elevated in patients with alcohol use disorder, indicating a dysregulated protease‐antiprotease inflammatory balance characterised by decreased SERPINA3. ELANE showed excellent diagnostic specificity(AUC = 0.8683), supporting its potential utility as a neuroinflammatory biomarker for AUD.

Uncovering Exotic Topological Quantum States in Pure and Magnetically‐Doped Pyrite OsS2

open access: yesAdvanced Quantum Technologies, EarlyView.
Pyrite‐structured OsS2 is identified as a fragile topological insulator with an unprecedented 602 meV bandgap, featuring helical surface states and van Hove singularities amenable to ARPES verification. Magnetic doping with Pd, Fe, Ni, or Co induces phase transitions to strong topological insulators, semimetals, 3D quantum anomalous Hall insulators ...

Chiral anomaly in toroidal carbon nanotubes [PDF]

open access: yesPhysics Letters A, 2002
It is pointed out that the chiral anomaly in 1+1 dimensions should be observed in toroidal carbon nanotubes on a planar geometry with varying magnetic field. We show that the chiral anomaly is closely connected with the persistent current in a one-dimensional metallic ring.

Illicit Drug‐Derived Volatile Organic Compounds as Markers for Application in Noncontact Detection Technology

open access: yesThe Chemical Record, EarlyView.
This review highlights the characteristic odor markers of illicit drugs, emphasizing volatile markers from both natural and synthetic sources, and explores the shift from canine‐based detection to emerging noncontact sensing technologies. Illicit drug use remains a global concern, requiring effective detection methods to counter evolving concealment ...

Global gravitational anomalies from perturbative chiral anomalies

open access: yesPhysics Letters B, 1985
Abstract The relation between (4k − 2)-dimensional global gravitational anomalies and perturbative chiral anomalies in 4k dimensions is clarified using an open space generalization of the Atiyah-Patodi-Singer index theorem. These anomalies are then reduced to a chiral anomaly in a two-dimensional Schwinger model. It is argued that “all” anomalies can

A Helicity‐Based Analysis of the Stratospheric Polar Vortex Evolution

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.
Abstract The Arctic atmosphere in the winter months of the Northern Hemisphere is influenced by a stratospheric polar vortex, characterized by strong westerly circumpolar winds and extremely low temperatures. These vortices impact surface weather in various ways, and their dynamics may be affected by recent anthropogenic climate change.

On the anomaly interpretation of amplitudes in self-dual Yang-Mills and gravity

open access: yesJournal of High Energy Physics
We investigate the integrability anomalies arising in the self-dual sectors of gravity and Yang-Mills theory, focusing on their connection to both the chiral anomaly and the trace anomaly.
