Private Governance, Hegemonic Struggles, and Institutional Outcomes in the Transnational Cotton Commodity Chain [PDF]

Journal of World-Systems Research, 2015
Transnational firms have rolled out new forms of private governance at the same time as the rise of new economic powerhouses like China has fomented growing inter-state tensions.

Light Quark Spin-Flavor Symmetry for Baryons Containing a Heavy Quark in Large N QCD [PDF]

Phys.Lett.B315:431-437,1993, 1993
The couplings and interactions of baryons containing a heavy quark are related by light quark spin-flavor symmetry in the large $N$ limit. The single pion coupling constant which determines all heavy quark baryon-pion couplings is equal to the pion coupling constant for light quark baryons.

Quark Number Susceptibility with Finite Quark Mass in Holographic QCD [PDF]

Prog. Theor. Phys. 126 (2011), 735-751, 2010
We study the effect of a finite quark mass on the quark number susceptibility in the framework of holographic QCD. We work in a bottom-up model with a deformed AdS black hole and D3/D7 model to calculate the quark number susceptibility at finite temperature with/without a finite quark chemical potential. As expected the finite quark mass suppresses the

Quark mass density- and temperature- dependent model for bulk strange quark matter [PDF]

Phys.Rev. C65 (2002) 035202, 2002
It is shown that the quark mass density-dependent model can not be used to explain the process of the quark deconfinement phase transition because the quark confinement is permanent in this model. A quark mass density- and temperature-dependent model in which the quark confinement is impermanent has been suggested.

Quark running mass and vacuum energy density in truncated Coulomb gauge QCD for five orders of magnitude of current masses [PDF]

, 2010
We study in detail the effect of the finite current quark mass on chiral symmetry breaking, in the framework of truncated Coulomb gauge QCD with a linear confining quark-antiquark potential. In the chiral limit of massless current quarks, the breaking of chiral symmetry is spontaneous.

Quark: Controllable Text Generation with Reinforced Unlearning [PDF]

Neural Information Processing Systems, 2022
Large-scale language models often learn behaviors that are misaligned with user expectations. Generated text may contain offensive or toxic language, contain significant repetition, or be of a different sentiment than desired by the user. We consider the

Tetra- and Penta-Quark Structures in the Constituent Quark Model [PDF]

Symmetry, 2020
With the development of high energy physics experiments, a large amount of exotic states in the hadronic sector have been observed. In order to shed some light on the nature of the tetraquark and pentaquark candidates, a constituent quark model, along ...

Effects of Gravitational Field of a Topological Defect on Statistical Properties of Heavy Quark-Antiquark Systems

East European Journal of Physics, 2022
In this paper, we determine eigen energies, eigenfunctions and statistical properties of non-relativistic heavy quarkonia interacting with the extended Cornel potential within a space-time generated by a cosmic-string.
