On the Limitations of Provenance for Queries With Difference [PDF]

open access: yes, 2011
The annotation of the results of database transformations was shown to be very effective for various applications. Until recently, most works in this context focused on positive query languages.

Text Mining in Bibliometrics and Science Mapping: A Methodological Review

open access: yesWIREs Computational Statistics, Volume 18, Issue 2, June 2026.
Text mining has become a foundational component of contemporary bibliometrics and science mapping, enabling systematic analysis of the semantic structure, thematic evolution, and cognitive organization of scientific fields. Integrating textual evidence with relational indicators enriches knowledge maps and supports more comprehensive, content‐sensitive

Testing List H-Homomorphisms [PDF]

open access: yes, 2011
Let $H$ be an undirected graph. In the List $H$-Homomorphism Problem, given an undirected graph $G$ with a list constraint $L(v) \subseteq V(H)$ for each variable $v \in V(G)$, the objective is to find a list $H$-homomorphism $f:V(G) \to V(H)$, that is, $

Can we repudiate ontology altogether?

open access: yesNoûs, Volume 60, Issue 2, Page 264-292, June 2026.
Abstract Ontological nihilists repudiate ontology altogether, maintaining that ontological structure is an unnecessary addition to our theorizing. Recent defenses of the view involve a sophisticated combination of highly expressive but ontologically innocent languages combined with a metaphysics of features—non‐objectual, complete but modifiable states

Deforming the Double‐Scaled SYK and Reaching the Stretched Horizon From Finite Cutoff Holography

open access: yesFortschritte der Physik, Volume 74, Issue 5, May 2026.
ABSTRACT We study the properties of the double‐scaled SYK (DSSYK) model under chord Hamiltonian deformations based on finite cutoff holography for general dilaton gravity theories with Dirichlet boundaries. The formalism immediately incorporates a lower‐dimensional analog of TT¯(+Λ2)$\text{T}\overline{\text{T}}(+\Lambda _2)$ deformations, denoted T2 ...

From Lorentz to SIM(2): contraction, four-dimensional algebraic relations and projective representations

open access: yesInternational Journal of Geometric Methods in Modern Physics
We present a comprehensive study on [Formula: see text] and [Formula: see text] groups, their representations and algebraic aspects. These groups, together with [Formula: see text], arise as the symmetry groups of Very Special Relativity (VSR), where full Lorentz invariance is reduced while retaining many relativistic consequences.

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

open access: yesDevelopment 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 ...

Projective and plane curves: a relation between algebra, topology, and complex analysis

open access: yes, 2022
Los ceros de un polinomio sobre un cuerpo algebraic revelan relaciones entre el álgebra, la topología, y el análisis complejo. Son curvas algebraicas y, en este trabajo de fin de grado, las estudiamos sobre C 2 (llamadas curvas afines) y sobre P 2 C (llamadas curvas proyectivas), haciendo especial énfasis en las curvas planas (curvas proyectivas sin ...
