Methods for assessing problem‐solving competencies in preschoolers: A scoping review

open access: yesReview of Education, Volume 14, Issue 2, August 2026.
Abstract Problem‐solving is an important 21st‐century skill and an indispensable part of early STEM (science, technology, engineering and mathematics) education. To effectively study the development of children's problem‐solving competencies and to evaluate the effectiveness of classroom interventions and programmes, researchers and educators need ...

BPS black holes, the Hesse potential, and the topological string [PDF]

open access: yes, 2010
The Hesse potential is constructed for a class of four-dimensional N = 2 supersymmetric effective actions with S- and T-duality by performing the relevant Legendre transform by iteration.

Excitations of the Myers-Perry black holes

open access: yesJournal of High Energy Physics, 2019
We demonstrate separability of the dynamical equations for all p-form fluxes in the Myers-Perry-(A)dS geometry, extending the earlier results for electromagnetic field.

What No Research Means: The Problematic of Time and Possibilities for Expansiveness in Interpretive Literacy Research

open access: yesReading Research Quarterly, Volume 61, Issue 3, July/August/September 2026.
ABSTRACT This article examines what becomes possible for interpretive literacy research when time is treated not as a neutral backdrop but as a central problematic. We argue that research does not merely trace temporal sequences; it actively creates temporalities that shape what becomes sensible, thinkable, and sayable within literacy studies.

On black holes in string theory

open access: yes, 2011
PhDThis thesis investigates black holes in string theory through string amplitudes and through gauge-gravity duality. The research presented in this thesis supports the claim that string theory is capable of a consistent quantum-mechanical description

Quantum Aspects of Black Holes [PDF]

open access: yes, 2006
In this thesis we study two quantum aspects of black holes, their entropy and the Hawking effect. First, we present a model for the statistical interpretation of black hole entropy and show that this entropy emerges as a result of missing information ...

Higher-Derivative Corrected Black Holes: Perturbative Stability and Absorption Cross-Section in Heterotic String Theory

open access: yes, 2006
This work addresses spherically symmetric, static black holes in higher-derivative stringy gravity. We focus on the curvature-squared correction to the Einstein-Hilbert action, present in both heterotic and bosonic string theory.

Year‐Round Haulout Activity of Harbor and Gray Seals Derived From Satellite Telemetry in Scandinavian Waters

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Seal haulout behavior is of interest in relation to energetics and abundance estimation. To assess year‐round and diel haulout patterns and estimate correction factors, data were obtained from 100 seals (66 harbor and 34 gray seals) tagged with satellite transmitters in Kattegat and the western Baltic Sea during 2004–2017.

Aspects of plane waves and Taub-NUT as exact string theory solutions [PDF]

open access: yes, 2004
This thesis is a study of some aspects of string theory solutions that are exact in the inverse string tension ɑ', and thus are valid beyond the low-energy limit.

Topological classes of thermodynamics of the static multi-charge AdS black holes in gauged supergravities: novel temperature-dependent thermodynamic topological phase transition

open access: yesJournal of High Energy Physics
In this paper, we investigate, in the framework of the topological approach to black hole thermodynamics, using the generalized off-shell Helmholtz free energy, the topological numbers of the static multi-charge AdS black holes in four- and five ...
