Supersymmetry in the false vacuum

A metastable state, or a false vacuum, is not an eigenstate of the Hamiltonian in quantum field theory. Its energy density has a non-zero imaginary part equal to its decay width. Therefore, supersymmetry cannot be exact in the false vacuum. We calculate the size of this effect using the path integral approach.Comment: 9 pages, latex, epsf, one figure appended (uuencoded postscript), complete postscript file is available at ftp://dept.physics.upenn.edu/pub/Kusenko/UPR679T.p

Unsupervised word embeddings capture latent knowledge from materials science literature.

The overwhelming majority of scientific knowledge is published as text, which is difficult to analyse by either traditional statistical analysis or modern machine learning methods. By contrast, the main source of machine-interpretable data for the materials research community has come from structured property databases1,2, which encompass only a small fraction of the knowledge present in the research literature. Beyond property values, publications contain valuable knowledge regarding the connections and relationships between data items as interpreted by the authors. To improve the identification and use of this knowledge, several studies have focused on the retrieval of information from scientific literature using supervised natural language processing3-10, which requires large hand-labelled datasets for training. Here we show that materials science knowledge present in the published literature can be efficiently encoded as information-dense word embeddings11-13 (vector representations of words) without human labelling or supervision. Without any explicit insertion of chemical knowledge, these embeddings capture complex materials science concepts such as the underlying structure of the periodic table and structure-property relationships in materials. Furthermore, we demonstrate that an unsupervised method can recommend materials for functional applications several years before their discovery. This suggests that latent knowledge regarding future discoveries is to a large extent embedded in past publications. Our findings highlight the possibility of extracting knowledge and relationships from the massive body of scientific literature in a collective manner, and point towards a generalized approach to the mining of scientific literature

Immersing the artist and designer in the needs of the clinician: evolving the brief for distraction and stress reduction in a new Child Protection Unit.

Engaging clinicians in the design of new, less stressful spaces in healthcare is an interdisciplinary challenge for artists and designers. The design brief is the primary means of ensuring shared understanding and success criteria for creative projects (Press and Cooper 2003) and highlights ambitions and constraints for the project. Conventionally the brief is prepared by the client and issued to the artist or designer. This assumes that the client knows at the outset how to articulate needs and is able to envisage the outcome. Alternative processes emerging through co-design and interdisciplinary working assume the brief is developed or evolved jointly as part of the process and is focused on the experience of the user. This paper focuses on the evolution of a meaningful brief for a Child Protection Unit in NHS Greater Glasgow & Clyde’s new Royal Hospital for Children. Development of the brief was driven by the art and design team and aimed at opening up mutual understanding with the clinicians. The visual mapping of dialogue between artist, interactive designer and clinicians provides a novel approach to understanding this key stage of the process. Fremantle co-ordinated the paper. Hepburn undertook the fieldwork and provided the analysis. Fremantle structured the paper and co-ordinated reviews with Hamilton and Sands

Language Teachers and Technology : Beliefs, Attitudes, and Knowledge

This study explores language teachers’ beliefs, knowledge, and attitudes toward technology integration. Amidst the COVID-19 pandemic, language teachers were compelled to adopt various technologies for remote teaching. Our findings reveal a strong belief among teachers in the importance of technology skills for effective classroom implementation. While positive attitudes toward technology adoption were prevalent, opinions varied on its impact on teaching abilities. Teachers recognized the benefits of technology for communication and creating instructional materials. Yet, views on student engagement with technology were diverse. The findings emphasized the influence of teacher background and attitude in shaping their utilization of technology, with implications for teacher professional development and the integration of technology into educational practices.journal articl
