Fully Quantum Perturbative Description of Correlated Stokes–Anti‐Stokes Scattering

physica status solidi (b), EarlyView.
The generation of Stokes‐anti‐Stokes (SaS) photon pairs with quantum correlations, like entanglement, has been developing recently, but a proper theoretical ground was missing. A fully quantum perturbative theory is provided to describe the four‐wave mixing contribution to the correlated SaS scattering, in which both matter and electromagnetic field ...

The Molecular Basis of Growth Control in Guanine Crystals

Small, EarlyView.
Precise control over guanine crystal morphology is achieved through biologically inspired, facet‐selective interactions. Simple synthetic polymers tune growth from prisms to needles and plate‐like biogenic forms by modulating multivalency, polarity, and functional‐group identity.

Nonclassical Measurement Error in Farmland Markets with Implications for Ricardian Analysis

American Journal of Agricultural Economics, EarlyView.
Abstract Nonclassical measurement error threatens the validity of empirical economic models. We examine the extent to which land value measures that are commonly used in studies of the US farmland market are subject to nonclassical measurement error. We consider differences in county‐level land values from two popular data sources: (1) self‐reported ...

Model pluralism for logic

Noûs, EarlyView.
Abstract It is well‐recognized in the sciences that a multitude of nonequivalent models are used by researchers to fulfill a range of goals, even for the same target system, a result known broadly as model pluralism. The possibility of the same form of pluralism occurring in logic, however, has not been adequately considered.

Progress of Programmed Cell Death in Steroid‐Induced Osteonecrosis of the Femoral Head

Orthopaedic Surgery, EarlyView.
Steroid‐induced osteonecrosis of the femoral head is a severe osteoarticular condition resulting from glucocorticoid overuse, characterized by femoral head bone structure collapse and cell death, now predominant among nontraumatic femoral head necroses.

Quantifiers for a Modal Future

Philosophical Perspectives, EarlyView.
ABSTRACT Future auxiliaries present a challenge to the classical analysis of modal expressions as existential or universal quantifiers over a contextually provided set of possible worlds: these expressions come with a distinct modal flavor, but their interaction with negation and the fact that future judgments come in degrees of confidence is ...

Models in Decision‐Making Under Risk and Uncertainty

Journal of Economic Surveys, Volume 40, Issue 1, Page 304-320, February 2026.
ABSTRACT This paper systematically compares dominant frameworks for modeling decision‐making under risk and uncertainty, evaluating their theoretical trade‐offs and practical relevance for economic research. We establish key criteria for model selection—including predictive accuracy, descriptive realism, computational tractability, and ecological ...

Fine‐Tuned Magnetic and Electrochemical Properties of a Series of Fe(II) Complexes with Asymmetric Jäger‐Type (N2O2)2− Ligands

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 1, January 6, 2026.
Asymmetrically substituted Jäger‐type ligands and their Fe(II) complexes show additive optical and redox trends. Ketone donors promote spin‐crossover while ester donors stabilize the high‐spin state, yet bulk materials display unexpected transitions governed by molecular symmetry and packing. A series of seven new asymmetrically substituted Jäger‐type (

The Rise of Health Economics: Transforming the Landscape of Economic Research

Health Economics, Volume 35, Issue 1, Page 52-68, January 2026.
ABSTRACT This paper explores the evolving role of health economics within economic research and publishing over the past 30 years. Historically, largely a niche field, health economics has become increasingly prominent, with the share of health economics papers in top journals growing significantly.

Planar and Pyramidal Pentacoordinate Selenium Atoms

Chemistry – A European Journal, Volume 31, Issue 72, December 23, 2025.
Planar (D5h) and pyramidal (C5v) dianionic clusters, SeM5X52− (M = LiK; X = FBr), showcase pentacoordinate selenium atoms stabilized by geometric confinement and electrostatic interactions with surrounding alkali and halogen atoms. Abstract A systematic computational exploration of the dianionic systems SeM5X52− (M = Li─Cs; X = F─I) was conducted to ...
