Parity of esteem for mental and physical health is a red herring [PDF]

open access: possibleBMJ, 2014
Millard and Wessely acknowledge how hard it is to know what “parity of esteem” between mental health and physical health really means.1 However, they avoid direct engagement with evidence that the problem with mental health services is also to do with the services themselves. Their two main points of “tackling excess mortality and stigma” is a …

Parity Violation in Atomic Physics

1991
Physicists have been convinced for a long time that the laws of nature do not distinguish between left and right, and therefore parity (mirror symmetry) is conserved in all interactions. The discovery in 1956 that parity is not conserved for the weak interaction governing β-decay had an immediate and profound influence on nuclear and elementary ...

Digital-Physical Parity for Food Fraud Detection

2019
Food fraud has an adverse impact on all stakeholders in the food production and distribution process. Lack of transparency in food supply chains is a strong factor contributing to food fraud. With limited transparency, the insights on food supply chains are fragmented, and every participant has to rely on trusted third parties to assess food quality ...

Parity nonconservation in atoms

1998
Introduction The role of atomic physics in precision tests of QED is well known. However, atomic physics has not until recently played much of a role in testing the weak interactions owing to the extremely small ratio ~ 10 −11 of the energy scale of atoms to the mass of the W ± and Z 0 bosons.

Parity Violation in Atomic Physics and Neutral Currents

1977
Using atomic physics experiments as a way to get information about electron-hadron neutral currents seems, at first sight, a hopeless enterprise. It is only for momentum transfer q of the order of a few hundred GeV that the neutral current electron-hadron amplitude Aw can complete with the electromagnetic one AEM.

On the incompatibility of parity, baryon number and supersymmetries in hadron physics

Il Nuovo Cimento A, 1976
Consider a theory with nontrivialS-matrix, nonvanishing masses and the property that to every mass belongs only a finite number of different types of particles. Suppose that it admits parity, baryon number and supersymmetries. We show that, if the theory accommodates a supermultiplet of hadrons and if all physically realizable vectors belonging to the ...
