Many areas of science today, like atomic and molecular physics, nuclear physics, astrophysics, laboratory plasma research etc., depend on data for ionic, atomic, and molecular collision processes. The purpose of the Special Issue “Atomic and Ionic Collisions with Formation of Quasimolecules” in Atoms is to engage a broad community of researchers to consolidate knowledge, make new discoveries, and to continue the exchange of ideas.

The impact of physics research carried out in Israel on the international literature is assessed from data on publication and citation counts. We have considered in this analysis all papers published from Israel and covered under six of the ten major sections of INSPEC's Physics Abstracts, January-June 1977 (covering condensed matter physics, nuclear and particle physics, atomic and molecular physics and biophysics and physical chemistry) as well as citations to these papers as seen from five annual editions of Science Citation Index, 1977-1981. An analysis of these data permits us to identify: (i) areas of research in which Israel is strong, (ii) highly cited publications, (iii) the distribution of citations over the years, and (iv) how quickly the papers get cited. Israel accounts for less than 1% of the world's physics publications, but undeniably physics done in Israel is an integral part of the mainstream of world physics. Israeli physicists place almost all their work in foreign journals, most of them published from the United States, the Nether lands and the United Kingdom. Many of these journals have a good standing as seen from their high impact factors and immediacy indices. Nearly all papers in our sample have originated in eight institutions, indicating that Israel is free from the common Third World malady of spreading the butter of R&D budget too thinly. Overall, Israeli physics appears to be productive in condensed matter physics, nuclear physics and atomic and molecular physics. However, chemical physics tops the list if one considers both the number of papers published and the cognitive impact these papers have had. Two areas where Israel did not publish much and yet had a few publica tions of high impact are: (i) special theories, interaction models and particle systematics, and (ii) biophysics. Surprisingly for a nation interested in both the military and civilian applications of nuclear energy, Israel's publications in nuclear physics are not as well cited as her publications in many other subfields of physics.

John Henry Carver made distinguished contributions to national and international physics, not only through his research in nuclear physics, atomic and molecular physics, and planetary atmospheric physics, but also as a scientific administrator. His years as the Elder Professor of Physics at the University of Adelaide saw him enter the field of rocket-based atmospheric physics by forging strong links with the nearby Weapons Research Establishment through which he had access to rockets to fly equipment developed in his laboratory and, eventually, to launch a small satellite developed and built by his team. This led to his appointment to the Scientific and Technical Subcommittee of the United Nations Committee on the Peaceful Uses of Outer Space, which he chaired for the record term of twenty-five years. As an academic administrator he was equally distinguished, serving on numerous boards and committees of the University of Adelaide before moving to Canberra as Director of the Australian National University's Research School of Physical Sciences, a position he held for fifteen years. In addition, he served with distinction on numerous national and international scientific advisory bodies. He was a passionate advocate for his School and his leadership will be long remembered.

<p>In this paper, we have solved the spinless Salpeter equation (SSE) with Hellmann potential under the framework of NIkiforov-Uvarov (NU) method. The energy eigenvalues and corresponding wave functions for this system express in terms of the Jacobi polynomial are also obtained. With the help of approximation scheme the potential barrier has been evaluated. The results obtained in this work would have many applications in nuclear physics, chemical physics, atomic and molecular physics, molecular chemistry and other related areas as the results under limiting cases could be used to study the binding energy and interaction of some diatomic molecules. As a guide to interested readers, we have provided numerical data which discuss the energy spectra for this system.</p><p> </p>

Phage lytic proteins are a clinically advanced class of novel enzyme-based antibiotics, so-called enzybiotics. A growing community of researchers develops phage lytic proteins with the perspective of their use as enzybiotics. A successful translation of enzybiotics to the market requires well-considered selections of phage lytic proteins in early research stages. Here, we introduce PhaLP, a database of phage lytic proteins, which serves as an open portal to facilitate the development of phage lytic proteins. PhaLP is a comprehensive, easily accessible and automatically updated database (currently 16,095 entries). Capitalizing on the rich content of PhaLP, we have mapped the high diversity of natural phage lytic proteins and conducted analyses at three levels to gain insight in their host-specific evolution. First, we provide an overview of the modular diversity. Secondly, datamining and interpretable machine learning approaches were adopted to reveal host-specific design rules for domain architectures in endolysins. Lastly, the evolution of phage lytic proteins on the protein sequence level was explored, revealing host-specific clusters. In sum, PhaLP can act as a starting point for the broad community of enzybiotic researchers, while the steadily improving evolutionary insights will serve as a natural inspiration for protein engineers.
