Morphological focus marking in Gùrùntùm (West Chadic)

The paper presents an in-depth study of focus marking in Gùrùntùm, a West Ch adic language spoken in Bauchi Province of Northern Nigeria. Focus in Gùrùntùm is marked morphologically by means of a focus marker a, which typically precedes the focus constituent. Even though the morphological focus-marking system of Gùrùntùm allows for a lot of fine-grained distinctions in information structure (IS) in principle, the language is not entirely free of focus ambiguities that arise as the result of conflicting IS- and syntactic requirements that govern the placement of focus markers. We show that morphological focus marking with a applies across different types of focus, such as newinformation, contrastive, selective and corrective focus, and that a does not have a second function as a perfectivity marker, as is assumed in the literature. In contrast, we show at the end of the paper that a can also function as a foregrounding device at the level of discourse structure

Considerations on Xi- reconstruction in LHCb

This paper describes an alternative method of charged hyperon reconstruction applicable to the LHCb experiment. It extends the seminal work of the FOCUS collaboration to the specific detector layout of LHCb and addresses the reconstruction ambiguities reported in their earlier work, leading to improvements in the reconstruction efficiency for the specific cases of Xi- and Omega- baryon decays to a charged meson and a Lambda baryon.Comment: 5 pages, 4 figure

Temporal coherence length of light in semiclassical field theory models

The following work is motivated by the conceptual problems associated with the wave-particle duality and the notion of the photon. Two simple classical models for radiation from individual emitters are compared, one based on sines with random phasejumps, another based on pulse trains. The sum signal is calculated for a varying number of emitters. The focus lies on the final signal's statistical features quantified by means of the temporal coherence function and the temporal coherence length. We show how these features might be used to experimentally differentiate between the models. We also point to ambiguities in the definition of the temporal coherence length.Comment: 7 pages, 3 figures.

The Role of Digital Technology in Sustainability: A Literature Review

Digital technologies can help to fulfill social needs through innovative and socially-embedded solutions. The research fields of digital sustainability, digital social innovation, and social entrepreneurship are about exploring how the tools of our digital age can be designed, adapted, and aligned to achieve local and global social needs. However, despite the current interest, there remain conceptual ambiguities regarding the focus of each field. This review examines current research by reviewing 24 articles across the Basket of Eight and two IS conferences. Our results clarify the different focus areas within each research field but also show that the three research fields overlap due to the remaining conceptual ambiguities. To enable more focus in future research, we discuss implications regarding the conceptual overlap, propose first steps to address them, and close by developing eight avenues for future research

One-nucleon transfer reactions and the optical potential

We provide a summary of new developments in the area of direct reaction theory with a particular focus on one-nucleon transfer reactions. We provide a status of the methods available for describing (d,p) reactions. We discuss the effects of nonlocality in the optical potential in transfer reactions. The results of a purely phenomenological potential and the optical potential obtained from the dispersive optical model are compared; both point toward the importance of including nonlocality in transfer reactions explicitly. Given the large ambiguities associated with optical potentials, we discuss some new developments toward the quantification of this uncertainty. We conclude with some general comments and a brief account of new advances that are in the pipeline.Comment: 7 pages, 5 figures, proceedings for the 14th International Conference on Nuclear Reaction Mechanisms, Varenna, June 201
