On the effective action of D-brane-anti-D-brane system [PDF]

open access: yesJournal of High Energy Physics, 2007
We examine the proposal for constructing the effective action of a D-brane-anti-D-brane system from the non-abelian extension of tachyon DBI action. We consider two prescriptions for the trace in the non-abelian tachyon DBI action. The usual trace and the symmetric trace prescription.

Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Uplift and towers of states in warped throat

open access: yesJournal of High Energy Physics, 2023
We investigate the connection between the distance conjecture and the uplift potential. For this purpose, we consider the concrete model, the warped deformed conifold embedded into Type IIB flux compactifications, with the uplift potential produced by D ...

Effects of Chatting Styles on Sharers’ Emotions During Online Conversations

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT Prior social sharing research suggests that cueing sharers to focus on recounting emotionally arousing details of a negative experience often increases negative affect, whereas cueing them to reconstrue the experience leads to emotional recovery.

Gravitational resonances in mimetic thick branes

open access: yesJournal of High Energy Physics, 2019
In this work, we investigate gravitational resonances in both single and double mimetic thick branes, which can provide a new way to detect the extra dimension. For the single brane model, we apply the relative probability proposed in [Phys. Rev.

Defects and D-brane monodromies [PDF]

open access: yesAdvances in Theoretical and Mathematical Physics, 2009
In this paper D-brane monodromies are studied from a world-sheet point of view. More precisely, defect lines are used to describe the parallel transport of D-branes along deformations of the underlying bulk conformal field theories. This method is used to derive B-brane monodromies in Kahler moduli spaces of non-linear sigma models on projective ...

Analysis of Composting Methods for Sustainable Management of Biodegradable Waste Using Decision‐Making Techniques

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract This study was conducted to evaluate different composting methods used in the sustainable management of biodegradable waste. In this context, composting stands out as an effective method for converting organic waste into more environmentally and economically beneficial products.

Policy Entrepreneurs and the Design of Administrative Reform: A Conceptual Framework and the Israeli Case

open access: yesEuropean Policy Analysis, EarlyView.
ABSTRACT What is the role of policy entrepreneurs in promoting the design of public administrative reform? We present a conceptual framework for assessing the influence of policy entrepreneurs on public administrative reform. We start by proposing a typology of the various policy entrepreneurs active in the administrative reform arena.

Non-Abelian black holes in string theory

open access: yesJournal of High Energy Physics, 2017
We study a family of 5-dimensional non-Abelian black holes that can be obtained by adding an instanton field to the well-known D1D5W Abelian black holes. Naively, the non-Abelian fields seem to contribute to the black-hole entropy but not to the mass due

Introduction to D-branes, with applications [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1997
A brief review of some of the central ideas, terminology and techniques of the technology of orientifolds and D-branes is presented. Some applications are reviewed, including the construction of dual solitonic strings in the context of string/string duality, the computation of the Bekenstein-Hawking entropy/area law for extremal black holes, and the ...
