An introduction to overlay journals

An overlay journal performs all the activities of a scholarly journal and relies on structural links with one or more archives or repositories to perform its activities. This paper offers a briefing on the contribution overlay journals can make to scholarly communication. It explains what ‘overlay’ services are, how overlay journals have evolved and what makes their contribution to scholarly communication so valuable

Sling effect in collisions of water droplets in turbulent clouds

We describe and evaluate the contribution of sling effect into the collision rate of the same-size water droplets in turbulent clouds. We show that already for Stokes numbers exceeding 0.2 the sling effect gives a contribution comparable to Saffman-Turner contribution, which may explain why the latter consistently underestimates collision rate (even with the account of preferential concentration).Comment: 7 pages, 6 figures; preprint submitted to Journal of Atmospheric Science

Development of RMJ: A mirror of the development of the profession and discipline of record management

The purpose of this paper is to examine critically the history of Records Management Journal on its 20th anniversary; it aims to review and analyse its evolution and its contribution in the context of the development of the profession and the discipline of records management. The paper seeks to provide the context and justification for the selection of eight articles previously published in the journal to be reprinted in this issue

Renormalon Subtraction from the Average Plaquette and the Gluon Condensate

A Borel resummation scheme of subtracting the perturbative contribution from the average plaquette is proposed using the bilocal expansion of Borel transform. It is shown that the remnant of the average plaquette, after subtraction of the perturbative contribution, scales as a dim-4 condensate. A critical review of the existing procedure of renormalon subtraction is presented.Comment: 7pages,one figure; Journal version (added references and introductory remarks

The Quest for Understanding in Relativistic Quantum Physics
