Adiabatic theorems for linear and nonlinear Hamiltonians

, 2009
Conditions for the validity of the quantum adiabatic approximation are analyzed. For the case of linear Hamiltonians, a simple and general sufficient condition is derived, which is valid for arbitrary spectra and any kind of time variation.

Adapting to Urban Heights: Multidimensional Gradients Drive Nest‐Selection Plasticity and Trade‐Offs in a Human‐Commensal Sparrow

Integrative Zoology, EarlyView.
Urban Eurasian tree sparrows exhibit pronounced nest‐site plasticity, exploiting vertical building space while preferring lower nest heights when sites are abundant. Nest decisions are driven by altitude and building height rather than other factors, indicating a shift toward anthropogenic resources in cities.

Hydrogen production by methanol steam reforming on NiSn/MgO-Al 2O3 catalysts: The role of MgO addition [PDF]

, 2011
The effect of the magnesia loading on the surface structure and catalytic properties of NiSn/MgO-Al2O3 catalysts for hydrogen production by methanol steam reforming has been investigated. The catalysts have been obtained by impregnation of γ-Al2O3 by the

Revised Swedish visual field standards for a driver's licence: Threshold perimetry as a predictor of eligibility according to the current Swedish and current Norwegian suprathreshold standards

Acta Ophthalmologica, EarlyView.
Abstract Purpose To explore whether threshold perimetry can predict fulfilment of the current Swedish and current Norwegian Esterman perimetry standards for Group 1 driver's licence, and differences in compliance between the former and current Swedish visual field standards.

Searching for safety: Working conditions and policing in a US emergency department

Medical Anthropology Quarterly, EarlyView.
Abstract In the United States, emergency departments aren't supposed to turn anyone away. They are the safety‐net of the safety‐net providing life‐saving care. Yet, what happens to healthcare when conditions are so strained that patients and staff lash out at each other? What happens when the safety net becomes a carceral net?

Analgesic effects of platelet‐rich fibrin (PRF): A systematic review

Periodontology 2000, EarlyView.
Abstract Background Platelet‐rich fibrin (PRF), a second‐generation autologous platelet concentrate, has gained significant interest for its anti‐inflammatory and regenerative characteristics. While its role in tissue healing is well‐recognized, the analgesic potential of PRF remains under‐investigated.
