Linear meson and baryon trajectories in AdS/QCD

open access: yes, 2007
An approximate holographic dual of QCD is constructed and shown to reproduce the empirical linear trajectories of universal slope on which the square masses of radially and orbitally excited hadrons join.

A numerical investigation on enhancing the performance of a diesel engine fuelled with diesel‐biodiesel blend using a diethyl ether as an additive

open access: yesEngineering Reports, Volume 6, Issue 11, November 2024.
Experimental setup of diesel‐biodiesel‐DEE blend test to find the optimum blend ratio. Also, the effect of variable inlet pressure using computer simulation was studied to find the optimum conditions. Abstract Globally, the encouragement of using renewable fuels like biodiesel for diesel engines is driven by concerns over the fossil fuel depletion and ...

Diversity and structural‐functional insights of alpha‐solenoid proteins

open access: yesProtein Science, Volume 33, Issue 11, November 2024.
Abstract Alpha‐solenoids are a significant and diverse subset of structured tandem repeat proteins (STRPs) that are important in various domains of life. This review examines their structural and functional diversity and highlights their role in critical cellular processes such as signaling, apoptosis, and transcriptional regulation.

A simple model for spectral swapping of supernova neutrinos

open access: yes, 2009
Neutrinos emitted from a core-collapse supernova can experience collective flavor transformation because of high neutrino fluxes. As a result, neutrinos of different flavors can have their energy spectra (partially) swapped, a phenomenon known as the ...

Total supply capability of electricity distribution networks considering flexible interconnection of low‐voltage service transformers

open access: yesIET Smart Grid, Volume 7, Issue 4, Page 386-399, August 2024.
The authors propose the total supply capability (TSC) of the low‐voltage flexible distribution network (LVFDN) for the first time. The influence mechanism for low‐voltage flexible interconnection on TSC is quantitatively analysed with a case study. Furthermore, suggestions for the planning and operation of LVFDN are given.

On the collapse in fourth order gravities

open access: yes, 2012
The gravitational collapse in fourth order theories of gravity defined by an arbitrary action of the scalar curvature shows significant deviations with General Relativity.

Asymmetric all‐pay auctions with spillovers

open access: yesTheoretical Economics, Volume 19, Issue 1, Page 169-206, January 2024.
When opposing parties compete for a prize, the sunk effort players exert during the conflict can affect the value of the winner's reward. These spillovers can have substantial influence on the equilibrium behavior of participants in applications such as lobbying, warfare, labor tournaments, marketing, and R&D races.

The Dynamics of Instability

open access: yesTheoretical Economics, Volume 19, Issue 1, Page 365-405, January 2024.
We study a model in which two players with opposing interests try to alter a status quo through instability‐generating actions. We show that instability can be used to secure longer‐term durable changes, even if it is costly to generate and does not generate short‐term gains.

Neutrino-electron scattering in noncommutative space

open access: yes, 2010
Neutral particles can couple with the $U(1)$ gauge field in the adjoint representation at the tree level if the space-time coordinates are noncommutative (NC). Considering neutrino-photon coupling in the NC QED framework, we obtain the differential cross

Optimal sequential contests

open access: yesTheoretical Economics, Volume 19, Issue 1, Page 207-244, January 2024.
I study sequential contests where the efforts of earlier players may be disclosed to later players by nature or by design. The model has many applications, including rent seeking, R&D, oligopoly, public goods provision, and tragedy of the commons. I show that information about other players' efforts increases the total effort. Thus, the total effort is
