Quark Mass and Flavour Dependence of the QCD Phase Transition [PDF]

, 2000
We analyze the quark mass and flavour dependence of the QCD phase transition temperature. When the lightest pseudo-scalar meson mass (m_PS) is larger than 2 GeV the critical temperature is controlled by the gluonic sector of QCD alone. For smaller values

Mass Expansions of Screened Perturbation Theory [PDF]

, 2001
The thermodynamics of massless phi^4-theory is studied within screened perturbation theory (SPT). In this method the perturbative expansion is reorganized by adding and subtracting a mass term in the Lagrangian. We analytically calculate the pressure and

A Simple and Rapid Test-card Method to Detect Hepatitis B Surface Antigen and Antibody: Potential Application in Young Children and Infants

Pediatrics and Neonatology, 2016
Hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) were conventionally determined by enzyme immunoassays. We aimed to apply a rapid, simple, and accurate method to detect HBsAg and its antibody.

Lattice Artefacts In The Non-Abelian Debye Screening Mass In One Loop Order [PDF]

, 1997
We compute the electric screening mass in lattice QCD with Wilson fermions at finite temperature and chemical potential to one-loop order, and show that lattice artefacts arising from a finite lattice spacing result in an enhancement of the screening ...

Mass Screening in Modified Gravity

, 2007
Models of modified gravity introduce extra degrees of freedom, which for consistency with the data, should be suppressed at observable scales. In the models that share properties of massive gravity such a suppression is due to nonlinear interactions: An ...
