Information retrieval or document retrieval? Terminological confusions and unrealistic goals in information science, exemplified in relation to generative artificial intelligence

Journal of the Association for Information Science and Technology, Volume 77, Issue 5, Page 714-726, May 2026.
Abstract ChatGPT and related technologies have revived an old issue in information science (IS) concerning information retrieval (IR) versus document retrieval. Since 1950, the term IR has primarily been used as a misnomer for document retrieval. This problematic terminology reflects a desire to go beyond documents and provide, in response to user ...

Illustrating Implications of Misaligned Causal Questions and Statistics in Settings With Competing Events and Interest in Treatment Mechanisms

Statistics in Medicine, Volume 45, Issue 10-12, May 2026.
ABSTRACT In the presence of competing events, many investigators are interested in a direct treatment effect on the event of interest that does not capture treatment effects on competing events. Classical survival analysis methods that treat competing events like censoring events, at best, target a controlled direct effect: the effect of the treatment ...

Pathways to gender‐transformative women's health aid: Comparative evidence from five donors

Development Policy Review, Volume 44, Issue 3, May 2026.
Abstract Motivation Gender equality and women's health remain priorities, yet recent fiscal retrenchment and shifting geopolitical agendas have narrowed the space for gender‐transformative programming. Despite growing donor endorsement of gender‐transformative approaches, substantial gaps persist between rhetorical commitment and operational practice ...

Which singular tangent bundles are isomorphic?

Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract Logarithmic and b$ b$‐tangent bundles provide a versatile framework for addressing singularities in geometry. Introduced by Deligne and Melrose, these modified bundles resolve singularities by reframing singular vector fields as well‐behaved sections of these singular bundles.

Ihm-Quasiorder and Derived Structures of Universal Algebras; 1-Algebraic Complete Algebras

Известия Иркутского государственного университета: Серия "Математика", 2015
The relation of so-called Ihm-quasiorder (defining a closure operator on subsets of direct powers of basic sets of universal algebras) with the such derived structures of these algebras as a lattices its algebraic subsets, lattices of its subalgebras ...

Lorentzian homogeneous structures with indecomposable holonomy

Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract For a Lorentzian homogeneous space, we study how algebraic conditions on the isotropy group affect the geometry and curvature of the homogeneous space. More specifically, we prove that a Lorentzian locally homogeneous space is locally isometric to a plane wave if it admits an Ambrose–Singer connection with indecomposable, non‐irreducible ...

Molecular Origins of Philicity: How Atomic Interactions Determine Miscibility and Diffusivity

ChemPhysChem, Volume 27, Issue 8, 28 April 2026.
Alterations in the atomic philicity, as represented by Lennard–Jones parameters, determine the miscibility of an alkane‐perfluoroalkane system. Some parameters enhance mixing, while others enhance phase separation.We present a computational study on the microscopic origin of molecular philicity, which determines the miscibility and diffusivity of ...

Robust Inverse Material Design With Physical Guarantees Using the Voigt‐Reuss Net

International Journal for Numerical Methods in Engineering, Volume 127, Issue 7, 15 April 2026.
ABSTRACT We apply the Voigt‐Reuss net, a spectrally normalized neural surrogate introduced in [38], for forward and inverse mechanical homogenization with a key guarantee that all predicted effective stiffness tensors satisfy Voigt‐Reuss bounds in the Löwner sense during training, inference, and gradient‐driven optimization.
