Screening in three-dimensional QED with arbitrary fermion mass [PDF]

open access: yes, 1998
We compute the quark--antiquark potential in three dimensional massive Quantum Electrodynamics for arbitrary fermion mass. The result indicates that screening prevails for any quark masses, contrary to the classical expectations, generalizing our ...

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

open access: yesPediatrics 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.

CT Examinations for COVID-19: A Systematic Review of Protocols, Radiation Dose, and Numbers Needed to Diagnose and Predict

open access: yes대한영상의학회지, 2021
Purpose Although chest CT has been discussed as a first-line test for coronavirus disease 2019 (COVID-19), little research has explored the implications of CT exposure in the population.

Implementation of the compulsory universal testing scheme in Hong Kong: Mathematical simulations of a household-based pooling approach

open access: yesFrontiers in Public Health, 2022
This study aims to propose a pooling approach to simulate the compulsory universal RT-PCR test in Hong Kong and explore the feasibility of implementing the pooling method on a household basis.

Fermions obstruct dimensional reduction in hot QCD [PDF]

open access: yes, 2000
We have studied, for the first time, screening masses obtained from glueball-like correlators in Quantum Chromodynamics with four light dynamical flavours of quarks in the temperature range 1.5T_c < T < 3T_c, where T_c is the temperature at which the ...

On Non-Abelian Thomas-Fermi Screening [PDF]

open access: yes, 1996
The Thomas-Fermi screening of non-Abelian gauge fields by fermions or screening of gluon fields in quark matter is discussed. It is described by an effective mass term which is, as with hard thermal loops, related to the eikonal for a Chern-Simons theory

Debye screening mass near deconfinement from holography

open access: yes, 2014
In this paper the smallest thermal screening mass associated with the correlator of the $CT$-odd operator, $\sim {\rm Tr}F_{\mu\nu}\tilde{F}^{\mu\nu}$, is determined in strongly coupled non-Abelian gauge plasmas which are holographically dual to non ...

Meson screening masses from lattice QCD with two light and the strange quark

open access: yes, 2011
We present results for screening masses of mesons built from light and strange quarks in the temperature range of approximately between 140 MeV to 800 MeV.

Inter-arm blood pressure difference and cardiovascular risk estimation in primary care: a pilot study

open access: yesBJGP Open, 2022
Background: Systolic inter-arm differences (IAD) in blood pressure (BP) contribute independently to cardiovascular risk estimates. This can be used to refine predicted risk and guide personalised interventions.
