In this paper we introduce a notion of spectral approximation for directed graphs. While there are many potential ways one might define approximation for directed graphs, most of them are too strong to allow sparse approximations in general. In contrast, we prove that f...

International audience; Air–water gas exchange experiments were carried out in a large wind wave tunnel in Marseille, France, to investigate gas transfer processes under energetic wind and wave fields, where macroscale breaking waves create bubble plumes (white caps) an...

Special issue on Software Engineering Curriculum Development; International audience; As new software engineering techniques emerge, there's a cognitive shift in how developers approach a problem's analysis and how they design and implement its software-based solution. ...

Luminescent sensors for ions and molecules have found numerous applications in areas such as biology, medicine, security, and environmental monitoring. However, designing portable sensors for differentiating similar chemical species, such as D 2 O in H 2 O, still remain...

ABSTRACTAlthough the relationship between management support and readiness for change is a well-studied topic, mediating variables in this relationship are rarely examined. This paper presents the findings of an investigation into the mediating role of psychological cap...

The aim of this project was to design and develop a group pump and solve associated technical issues for a construction company in Ireland. The design is based on a high shear colloidal group mixing and pumping rig. The initial machine has failed in terms of bearing and...

Pharmacologic HIF hydroxylase inhibitors (HIs) are effective for the treatment of anemia in chronic kidney disease patients and may also be beneficial for the treatment of diseases such as chronic inflammation and ischemia-reperfusion injury. The selectivities of many H...

Studies expressing concern over the continued underparticipation of women in politics rest on the assumption that increasing the number of female representatives in democracies leads to greater substantive representation of women's policy interests. This article advance...

AbstractObjective. Chiari I malformation may be treated with foramen magnum decompression (FMD). We aim to describe the symptoms with which patients initially present, and to determine the number and type of complications occurring after FMD for Chiari I malformation. M...

Abstract Background Although reports suggest that most individuals with coronavirus disease 2019 (COVID-19) develop detectable antibodies postinfection, the kinetics, durability, and relative differences between immunoglobulin M (IgM) and immunoglobulin G (IgG) respons...
