We compute the quark–antiquark potential in three dimensional massive Quantum Electrodynamics. The result indicates that screening prevails for large quark masses, contrary to the classical expectations. The classical result is reproduced for small separation of the quarks.

ABSTRACT This study investigated the efficacy of using inoculation theory in developing students' skills in resisting pressures involved with drinking and driving situations. Inoculation theory stems from psychosocial investigations that have demonstrated that resistance to specific opposing arguments can be increased if subjects are familiar with these arguments. The study sample was coihprise...

Global climate change has advanced the breeding phenology of many avian species. However, raptors’ phenologies may not respond in same way to factors that influence passerine dates. We studied reproduction suburban and rural Red-shouldered Hawks ( Buteo lineatus ) southern Ohio, United States, from 1997 2020. Mean hatching dates for 786 broods were 24 April [Julian day: 114.1 ± 0.3 d (SE)] bird...

The aim of this short series of lectures is to give some impression of what life as a mathematician is like. It has taken me to many parts of the world, and enable me to work with extraordinary people from many different cultures. There will be some mathematical content in the lectures. As Julian Havel said, mathematics is not a spectator sport; I will expect some engagement from you. You may a...

In the nal few years of his life, Julian Schwinger proposed that the \dynamical Casimir e ect" might provide the driving force behind the puzzling phenomenon of sonoluminescence. Motivated by that exciting suggestion, I have computed the static Casimir energy of a spherical cavity in an otherwise uniform material with dielectric constant and permeability . As expected the result is divergent; y...

The purpose of this paper is to pick up the threads of a debate about the ontology of becoming in spacetime that was triggered by a provocative article published by Nicholas Maxwell in 1985. This debate is itself merely a recent episode in a long dialogue that goes back at least as far as the time of Parmenides and Heraclitus (Savitt 2001). Here is the question around which this debate centres:...
