EPJ D Highlight - The key to ion beams’ polarisability

Polarisability for series of multi-electron ions is now available

Polarisability determines the force with which an inhomogeneous external electric field acts on the ions of an ion beam. However, it can be quite tricky to obtain accurate values for this force. Now, two German theoretical chemists, Volker Koch from Bielefeld University and Dirk Andrae from the Free University Berlin, have devised formulas providing the polarisability of atomic ions as a function of their total charge number. Their findings, about to be published in EPJ D, have implications for many applications, ranging from the use of ion beams for research purposes or as a source for dopant atoms in semiconductor manufacturing to the modelling of planetary and stellar atmospheres.

EPJ B Highlight - When diffusion depends on chronology

Motorways are an example of nodes connected by edges studied as complex networks.

Study shows that the order of events taking place in complex networks may dramatically alter the way diffusion occurs

The Internet, motorways and other transport systems, and many social and biological systems are composed of nodes connected by edges. They can therefore be represented as networks. Scientists studying diffusion over such networks over time have now identified the temporal characteristics that affect their diffusion pathways. In a paper just published in EPJ B, Renaud Lambiotte and Lionel Tabourier from the University of Namur, Belgium, together with Jean-Charles Delvenne from the Catholic University of Louvain, Belgium, show that one key factor that can dramatically change a diffusion process is the order in which events take place in complex networks.

EPJ B Highlight - Semantics on the basis of words’ connectivity

Illustration of a tourist walk.

It is now possible to identify the meaning of words with multiple meanings, without using their semantic context

Two Brazilian physicists have now devised a method to automatically elucidate the meaning of words with several senses, based solely on their patterns of connectivity with nearby words in a given sentence – and not on semantics. Thiago Silva and Diego Amancio from the University of São Paulo, Brazil, reveal, in a paper just published in EPJ B, how they modelled classics texts as complex networks in order to derive their meaning. This type of model plays a key role in several natural processing language tasks such as machine translation, information retrieval, content analysis and text processing.

EPJ B Highlight - Averting worse economic collapses

The local separation of one equilibrium surface from another.

A new study shows how specific parameters can help us steer clear of tipping points in dynamic systems, such as entire economies.

By managing macro-economic parameters, scientists believe that—unlike previously thought—it is possible to steer an economy around irreversible changes in its complex dynamics and avert potential economic disasters. These findings, just published in EPJ B, stem from the theoretical work of Michael Harré and colleagues at the Complex Systems Group at the University of Sydney, Australia.

EPJ Plus awarded its first Impact Factor

The release of the journal Impact Factors (IF) by Thomson Reuters confirms once more the position of EPJ as a premium provider of relevant and strictly peer-reviewed research in the physical sciences and beyond. We are especially proud of the fast-paced development of our newer journals: EPJ Plus, launched only in 2011, was already awarded its first IF (1.302) and EPJ H – Historical Perspectives in Contemporary Physics, launched in 2010, progressed from an IF of 1.182 in 2011 to an impressive 2.375 for 2012.

The full overview of 2012 EPJ Impact Factors is given here.

EPJ E Colloquium - Glassy dynamics and irreversible adsorption in thin films of soft matter

alt

Thin films of liquids and polymers are interesting systems for those seeking to test glass transition theories and their prediction of a characteristic transition length scale of a few nanometers. The anomalous phenomena observed in some of these nano-confined films has greatly advanced our understanding of theoretical and experimental soft matter physics.

These films are treated as equilibrium systems where surfaces and interfaces introduce monotonous long-range mobility gradients. Considering finite size and interfacial effects provides an intuitive but oversimplifies picture that falls short of explaining many phenomena, such as enhancement of segmental mobility near an absorbing surface or long-lasting metastable states in the liquid.

EPJ celebrates 15th anniversary

EPJ 15th anniversary logo

The European publishing partnership for physics, The European Physical Journal (EPJ), celebrates its 15th year in 2013.

During this time, EPJ has launched new open access titles, either in response to the emergence of new research fields at the interface between more established subjects, or to fill obvious gaps in the EPJ catalogue. After the early launches of EPJ Web of Conferences (the open access proceedings repository) in 2009 and EPJ Photovoltaics in 2010, 2012 witnessed the launch of EPJ Data Science. This year, three new journals are about to join them: EPJ Nonlinear Biomedical Physics, EPJ Techniques and Instrumentation and EPJ Quantum Technology. EPJ is also pleased to see EPJ C – Particles and Fields lined up for conversion into a fully open access journal under SCOAP3 (Sponsoring Consortium for Open Access Publishing in Particle Physics).

A team of Chinese scientists evaluates the impact of a website based on the interaction between its users with the entire Web

A new study shows that small websites, in terms of daily user flux based on number of clicks, have a disproportionally high impact when it comes to traffic generation and influence compared to larger websites. These findings, just published in EPJ B, have implications for estimating the value of sites and related advertising revenue. They result from the work of Lingfei Wu from the City University of Hong Kong and Jiang Zhang from the School of Management, at Beijing Normal University, China.

EPJ E Highlight - How cells get a skeleton

Stress generated by nano-motors within animal cells can lead to the creation of a condensed layer of filaments beneath the outer cell membrane

The mechanism responsible for generating part of the skeletal support for the membrane in animal cells is not yet clearly understood. Now, Jean-François Joanny from the Physico Chemistry Curie Unit at the Curie Institute in Paris and colleagues have found that a well-defined layer beneath the cell outer membrane forms beyond a certain critical level of stress generated by motor proteins within the cellular system. These findings, which offer a new understanding of the formation of this so-called cortical layer, have just been published in EPJ E.
