We present a formulation of relativistic linear response time-dependent density functional theory for the calculation of electronic excitation energies in the framework of the four-component Dirac-Coulomb Hamiltonian. This approach is based on the noncollinear <i>ansatz</i> originally developed by Scalmani and Frisch [J. Chem. Theory Comput. 8, 2193 (2012)] and improves upon the past treatment of ...

Epifaunal communities from the poorly studied Arctic deep sea of the Chukchi Borderland region were investigated to: (1) determine differences in community structure among ridges, plateau with pockmarks, and much deeper basins as three main habitat types, (2) analyse the environmental factors that might shape these communities, and (3) investigate biogeographic affinities dominating the epifaunal ...

Miguel de Cervantes’ posthumous novel, <i>Los trabajos de Persiles y Sigismunda, historia setentrional</i>, published in 1617, has in the past decades received renewed attention from Cervantes scholars. This article gives an overview of the main perspectives of current research at the 400^th anniversary of the novel that the author himself considered his literary testament. It concludes ...

Using transition theory from political science, this paper analyses how the lives of children of Norwegians punished for collaboration with the German occupant were adversely influenced by transitional justice after the return to democracy in 1945. The paper highlights how the complexity and hectic character of such regime changes are associated with a high risk for unintended social outcomes, a ...

From the invention of the atomic force microscope (AFM) in 1986, tremendous efforts have been put into developing this tool. The AFM has long been considered as one of the top choices to probe the nanoscale world with the ability to achieve nanoscale resolution imaging of surfaces under different environments. Advances in instrumentation combined with the exploitation of sophisticated data analysis ...

Numerous astronomical observatories were established across Europe over the course of the eighteenth century, rendering astronomy a distinct sub-branch of the Republic of Letters. Arguably, by the mid eighteenth century astronomy functioned as a denominationally neutral space and constituted a scientific discipline in the modern sense. Jesuits, Benedictines, Lutherans, Anglicans, Calvinists – all ...

<i>Background</i> - Sperm DNA integrity is considered essential for successful transmission of the paternal genome, fertilization and normal embryo development. DNA fragmentation index (DFI, %) has become a key parameter in the swine artificial insemination industry to assess sperm DNA integrity. Recently, in some elite Norwegian Landrace boars (boars with excellent field fertility records), a higher ...

Maritime activities in the Arctic Ocean is increasing and consequently the risk for an oil spill there is rising. Synthetic Aperture Radar (SAR) is used operationally to detect and monitor oil slicks and for sea ice monitoring and observations. Leads are often used for ship routing and within the leads newly formed sea ice is often present. Separation between the low backscatter areas that constitutes ...

Abstract The thesis aimed to study the emotional impact of video games and how these emotions shape the experience of the gaming. Data are from a case study and comprise both automatic facial coding of emotional expression and qualitative interviews. The facially expressed emotions were analyzed by means of a computer program named FaceReader. The results indicate that video games elicit a wide and ...
