Aims. We aim to study the variability properties of bright hard X-ray selected active galactic nuclei (AGN) in the redshift range between 0.3 and 1.6 detected in the Chandra Deep Field South (XMM-CDFS) by a long (∼3 Ms) XMM observation. Methods. Taking advantage of the good count statistics in the XMM CDFS, we search for flux and spectral variability using the hardness ratio (HR) techniques. We al

Background: The European directive on basic safety standards (Council directive 2013/ 59 Euratom) mandates dosimetry-based treatment planning for radiopharmaceutical therapies. The directive comes into operation February 2018, and the aim of a report produced by the Internal Dosimetry Task Force of the European Association of Nuclear Medicine is to address this aspect of the directive. A summary o

For the endohedral fullerene molecule HoLu2N@C80, it is shown that the endohedral HoLu2N unit may be oriented in a magnetic field. The Ho magnetic moment is fixed in the strong ligand field and aligns along the holmium-nitrogen axis. The torque of a magnetic field on the Ho magnetic moment leads to a hopping bias of the endohedral unit inclining to an orientation parallel to the externally applied

Pervasiveness and complexity of modern software are challenging engineers to design applications able to guarantee the desired quality of service despite unpredictable runtime variations in their execution environment. A variety of techniques have been proposed in the last year for the design of self-adaptive applications; however, most of them is tailored to specific applications or can provide l

Aluminium och Aluminiumlegeringar, som förutom aluminium innehåller några få procent av andra metaller, används i flera olika produkter såsom mobiltelefoner, flygplan, bilar och byggnader. Bland annat är aluminiumlegeringar det mest använda byggtekniska materialet efter järnlegeringar. Det breda användandet av aluminiumlegeringar förklaras av de många fördelaktiga egenskaperna. Till exempel har leIn this thesis, the studies of native and anodic oxides on both aluminum model single crystal surfaces as well as on aluminum alloys found in applications are presented. The focus has been on the characterization in situ as the oxide is growing by an electrochemical process called anodization. For the investigations, a combination of various X-ray scattering and spectroscopy methods, as well as el

The log-Gaussian Cox process (LGCP) is a popular point process for modeling noninteracting spatial point patterns. This paper extends the LGCP model to handle data exhibiting fundamentally different behaviors in different subregions of the spatial domain. The aim of the analyst might be either to identify and classify these regions, to perform kriging, or to derive some properties of the parameter

Purpose: The purpose of this paper is to analyse the communication management of the Swedish and Norwegian Governments during the 2015-2016 refugee crisis. It does so in the context of recent debates into public diplomacy (PD) and nation branding, on the understanding that governments seek to manage their reputations in order to attract trade, investment and tourism, as well as generate broader in

Pincer complexes attract considerable attention both as interesting objects for fundamental studies and efficient catalysts. This review describes a relatively new offshoot of the field - namely, the chemistry of iridium complexes with aliphatic PCsp3P non-innocent pincer ligands. High flexibility, often combined with possibility to activate internal C-H bonds, offers several new patterns of metal
