Peierls Dimerization with Non-Adiabatic Spin-Phonon Coupling [PDF]

, 1998
We study the magnetic properties of a frustrated Heisenberg spin chain with a dynamic spin-phonon interaction. By Lanczos diagonalization, preserving the full lattice dynamics, we explore the non-adiabatic regime with phonon frequencies comparable to the

Incommensurate antiferromagnetic fluctuations in single-crystalline LiFeAs studied by inelastic neutron scattering

, 2014
We present an inelastic neutron scattering study on single-crystalline LiFeAs devoted to the characterization of the incommensurate antiferromagnetic fluctuations at $\mathbf{Q}=(0.5\pm\delta, 0.5\mp\delta, q_l)$.

Uncertainty in the determination of soil hydraulic parameters and its influence on the performance of two hydrological models of different complexity [PDF]

, 2009
Data of soil hydraulic properties forms often a limiting factor in unsaturated zone modelling, especially at the larger scales. Investigations for the hydraulic characterization of soils are time-consuming and costly, and the accuracy of the results ...

Children's Ability to Identify and Describe Dysphonia: A Multimethod Study

International Journal of Language &Communication Disorders, Volume 61, Issue 1, January/February 2026.
ABSTRACT Background Engaging children with voice therapy is a commonly reported clinical challenge. It is unknown whether this is because children cannot always perceive dysphonia, or whether clinicians do not explain it in age‐appropriate terms. Aims This research aimed to analyse whether children can identify the presence of dysphonia in other ...

International Expert Consensus on Defining Skin of Color and Delivering Equitable Dermatologic Care

International Journal of Dermatology, Volume 65, Issue 1, Page 28-40, January 2026.
Gaps in dermatologic care for patients with skin of color (SOC), impacts and strategies to promote inclusivity. ABSTRACT Dermatological practice faces significant challenges in meeting the needs of populations with skin of color (SOC). Patients with SOC face disparities, including misdiagnoses and inequitable treatment outcomes.

Softening of Cu-O bond stretching phonon in tetragonal HgBa$_2$CuO$_{4+\delta}$

, 2004
Phonons in nearly optimally doped HgBa$_2$CuO$_{4+\delta}$ were studied by inelastic X-ray scattering. The dispersion of the low energy modes is well described by a shell model, while the Cu-O bond stretching mode at high energy shows strong softening ...

Reliability and Validity of the Italian Translation of the Updated Version of the Pressure Ulcer Knowledge Assessment Tool (PUKAT 2.0)

International Wound Journal, Volume 23, Issue 1, January 2026.
ABSTRACT The study aimed to translate the PUKAT 2.0 tool from English to Italian. This was an adaptation and validation study; the validity of the Italian version was determined through content validity, item validity and construct validity. The reliability of the instrument was assessed by conducting a test–retest analysis on a sample of 62 nurses ...
