Nature has recently published a Correspondence claiming the absence of fame biases in the editorial choice. The topic is interesting and deserves a deeper analysis than it was presented because the reported brief analysis and its conclusion are somewhat biased for many reasons, some of them are discussed here. Since the editorial assessment is a form of peer-review, the biases reported on external peer-reviews would, thus, apply to the editorial assessment, too. The biases would be proportional to the elitist level of a journal; the more elitist a journal, the more biased its decisions, unavoidably. The bias could be intentional or unintentional, conscious or subconscious, reflecting our imperfect human nature. © 2015 Akadémiai Kiadó, Budapest, Hungary

This paper describes a full-scale experiment of pile-supported embankments on soft soil, which is conducted within the French national research project, Amélioration des Sols par Inclusions RIgides (ASIRI), to provide a new design method. This experiment shows the great influence of a granular platform reinforced with geosynthetics in load-transfer mechanisms. The measurements of geosynthetic strains highlight that the maximum strain takes place at the vicinity of pile heads during the construction of an embankment. Measurements also show that the load-transfer behavior of a platform reinforced by a single geotextile is different from that of a platform reinforced by two geogrids, although the final settlement is the same in both sections. From the important measurement data of this full-scale experiment, some considerations on the design and the efficiency evaluation have been proposed. © 2012 American Society of Civil Engineers.

A new trend to assign some authors as 'first co-authors' is noticeable in scientific publications as a statement highlighting that two or more authors 'contributed equally' to a reported work. However, the requirements of scientific rigor, honesty, and accuracy in academic standards make such statements invalid and, thus, should be avoided. A potential solution is to specify the role of each co-author, from study conception to communication of results, and let readers judge the importance of each contribution by themselves. Alternatively, authors should demonstrate how they contributed 'equally' when they are defined as 'equal contributors'. © 2016 Elsevier Ltd.

Noise reduction for passengers' comfort in transport industry is now an important constraint to be taken into account during the design process. This process involves to study several configurations of the structures immersed in a given acoustic cavity in the context of an optimization, uncertainty, or reliability study for instance. The finite element method may be used to model this coupled fluid-structure problem but needs an interface conforming mesh for each studied configuration that may become time consuming. This work aims at avoiding this remeshing step by using noncompatible meshes between the fluid and the structures. The immersed structures are supposed to be thin shells and are localized in the fluid domain by a signed distance level-set. To take into account the pressure discontinuity from one side of the structures to the other one, the fluid pressure approximation is enriched according to the structures positions by a Heaviside function using a partition of unity strategy (extended finite element method). The same fluid mesh of the empty cavity is then used during the whole parametric study. The method is implemented for a three-dimensional fluid and tested on academic examples before being applied to an industrial-like case. © 2012 John Wiley & Sons, Ltd.

A review of the state of the art of adsorption heat powered heat pumps is presented. Interesting results on solar cooling, advanced cycles and consolidated materials were obtained in early developments until 1995 but, at that time, commercialization was not successful. Recently, breakthroughs were achieved on materials (including composite ones) and on coated surfaces but no obvious progresses have been obtained on advanced cycles and this is a gap to be completed. In parallel, commercialization has improved with the perspectives of the boiler new market. A promising future for those components exists if the recent and ongoing innovation yields more efficient commercialized products. © 2013 Elsevier Ltd. All rights reserved.
