Multiple Plasmon Satellites in Na and Al Spectral Functions from Ab Initio Cumulant Expansion

he valence photoemission spectra of alkali metals exhibit multiple plasmon satellite structure. The calculated spectral functions within the GW approximation show only one plasmon satellite at too large binding energy. In this Letter we use the cumulant expansion approach to obtain the spectral functions of Na and Al from ab initio calculations including the effects of band structure. The GW spect

Usage-Based Reading - An Experiment to Guide Reviewers with Use Cases

Reading methods for software inspections are used for aiding reviewers to focus on special aspects in a software artefact. Many experiments have been conducted for checklist-based reading and scenario-based reading concluding that the focus is important for software reviewers. This paper describes and evaluates a reading technique called usage-based reading (UBR). UBR utilises prioritised use case

Adapting a causality model of technical systems to represent socio-technical systems: A Case study from the BoP

The base of the world economic pyramid, generally called the base of the pyramid (BoP), consists of four billion people with average daily income of four dollars. Over the past several years, the design and development of products and services for BoP markets has been investigated by several authors from different disciplines. While some authors suggest a systems approach to design and develop pro

A 'Book' of Psalms?

Since the 1980’s, a slightly new shift in focus has emerged in the research on the Book of Psalms. Even if such a shift never occurs without precursors, it can be seen as a distinct move away from being primarily interested in original (cultic) contexts of individual psalms, and towards an increasing focus on the arrangement of these psalms into a book. The redaction history and the structure of t
