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

, 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

Journal 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 ...

Geography and ‘The New’

Transactions of the Institute of British Geographers, Volume 51, Issue 3, September 2026.
ABSTRACT This Intervention reflects on the multiple, contradictory and ambivalent relations human geography has with ‘the new’. Some sort of relation with the new is an inescapable and necessary part of all practices of knowledge generation. Newness, whether it be an empirical finding, an idea, a concept or an approach, can fuel the interest, wonder ...

Topological defects in low-energy string gravity [PDF]

, 1999
Cosmologists are interested in topological defects as a possible source for the primordial density perturbations which seeded structure formation through gravitational instability.

Microscopic unitary description of tidal excitations in high-energy string-brane collisions [PDF]

, 2013
The eikonal operator was originally introduced to describe the effect of tidal excitations on higher-genus elastic string amplitudes at high energy.

Black hole thermodynamics with dynamical lambda

Journal of High Energy Physics, 2017
We study evolution and thermodynamics of a slow-roll transition between early and late time de Sitter phases, both in the homogeneous case and in the presence of a black hole, in a scalar field model with a generic potential having both a maximum and a ...

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

Review 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 ...

Competition and payments to African chiefs on the Gold Coast during the slave trade, 1679‒1704

The Economic History Review, Volume 79, Issue 3, Page 1052-1081, August 2026.
Abstract The manuscript records of the Royal African Company show that the Company paid African chiefs for access to trade along the caravan routes on the Gold Coast in the seventeenth century. This paper documents and examines these payments. Using an event study, I establish that after the Glorious Revolution in 1688 when the Company's monopoly in ...

Aspects of compactifications and black holes in four-dimensional supergravity [PDF]

, 2010
In the 20th century, theoretical physics has seen the development of General Relativity and the Standard Model of elementary particles. These theories describe, with great precision, gravity and all known matter, respectively. However, it is not possible
