A case for resonant X‐ray Bragg diffraction by a collinear antiferromagnet Li2Ni3P4O14

open access: yesActa Crystallographica Section B, Volume 81, Issue 6, Page 582-586, December 2025.
Amplitudes for resonant X‐ray diffraction by collinear antiferromagnet Li2Ni3P4O14 that include permitted Dirac multipoles, e.g. anapoles, are investigated. Chiral signatures for the rotation of X‐ray helicity are described.Magnetic axial and polar (Dirac) nickel multipoles contribute to resonant X‐ray Bragg amplitudes in a symmetry‐informed analysis ...

Raising the visibility of protected data: A pilot data catalog project [PDF]

open access: yes, 2020
Sharing research data that is protected for legal, regulatory, or contractual reasons can be challenging and current mechanisms for doing so may act as barriers to researchers and discourage data sharing.

Ambulatory Arterial Stiffness Index: Regression Method Comparison and Its Association With Pulse Pressure and Circadian Patterns

open access: yesThe Journal of Clinical Hypertension, Volume 27, Issue 12, December 2025.
ABSTRACT The Arterial Stiffness Index (AASI) is a calculation obtained through Ambulatory Blood Pressure Monitoring (ABPM), and is an indirect measure of the elastic properties of the arterial wall; but there is heterogeneity in its scope as a predictor of vascular wall health.

Soft‐Layered Composites with Wrinkling‐Activated Multi‐Linear Elastic Behavior, Stress Mitigation, and Enhanced Strain Energy Storage

open access: yesAdvanced Engineering Materials, Volume 27, Issue 22, November 2025.
In this study, exciting new bi‐/multi‐linear elastic behavior of soft elastic composites that accompany the activation of wrinkling in the embedded interfacial layers is analyzed. The new features and performance of these composite materials, including dramatic enhancements in energy storage, can be tailored by the concentration of interfacial layers ...

Reachability in Higher-Order-Counters

open access: yes, 2013
Higher-order counter automata (\HOCS) can be either seen as a restriction of higher-order pushdown automata (\HOPS) to a unary stack alphabet, or as an extension of counter automata to higher levels.
