Radiation from a D-dimensional collision of shock waves: a remarkably simple fit formula

open access: yes, 2012
Recently, in arXiv:1105.2298 [hep-th], we have estimated the energy radiated in the head-on collision of two equal D-dimensional Aichelburg-Sexl shock waves, for even D, by solving perturbatively, to first order, the Einstein equations in the future of ...

Multi-black holes and instantons in effective string theory [PDF]

open access: yes, 1996
The effective action for string theory which takes into account non-minimal coupling of moduli admits multi-black hole solutions. The euclidean continuation of these solutions can be interpreted as an instanton mediating the splitting and recombination ...

The Impact of Artificial Intelligence on Energy Conservation and Emission Reduction: Evidence From China's Listed Firms

open access: yesInternational Studies of Economics, Volume 20, Issue 4, Page 410-430, December 2025.
ABSTRACT Artificial intelligence (AI) plays an increasingly pivotal role in advancing sustainable economic development. While existing literature predominantly examines the environmental impact of AI technologies from national or sectoral perspectives, this study provides a micro‐level analysis of its effects on energy conservation and emission ...

A Note on the Collision of Reissner-Nordstr\"om Gravitational Shock Waves in AdS

open access: yes, 2012
We study the collision of two Reissner-Nordstr\"om gravitational shock waves in AdS and show that the charge completely prevents the formation of marginally trapped surfaces of the Penrose type with topology S^(D-2), independently of the energy and the ...

How Social‐Symbolic Work Changes Places

open access: yesJournal of Management Studies, Volume 62, Issue 8, Page 3425-3460, December 2025.
Abstract We advance the social‐symbolic work perspective by developing an understanding of places as objects characterized by location, materiality, function, and symbolic meaning and which can be changed through social‐symbolic work. Drawing from a longitudinal study of the ‘Empty Homes’ Programme in England, our analysis identifies an unfolding ...

Model Dependence of $W_R$ Searches at the Tevatron

open access: yes, 1993
We explore the sensitivity of the on-going Tevatron search for charged, right-handed gauge bosons, $W_R^{\pm}$, to various model dependent assumptions such as the magnitude of the $SU(2)_R$ gauge coupling, the values of the right-handed Kobayashi-Maskawa
