In the holographic approach to cosmology, cosmological observables are described in terms of correlators of a three-dimensional boundary quantum field theory. As a concrete model, we study the $3D$ massless $SU(N)$ scalar matrix field theory with a $\phi^4$ interaction. On the lattice, the energy-momentum tensor (EMT) in this theory can mix with the operator $\phi^2$. We utilize the Wilson Flow to renormalize the EMT on the lattice, and present numerical results for the mixing coefficient for $N = 2$. Obtaining the renormalized EMT will allow us to make predictions for the CMB power spectra in the regime where the dual QFT is non-perturbative., Comment: 10 pages, 3 figures, presented at the 38th International Symposium on Lattice Field Theory - LATTICE2021 - 26-30 July, 2021, Massachusetts Institute of Technology

This is the first report of a disseminated protozoal infection in a wild feathertail glider (Acrobates pygmaeus) from south-eastern Australia. The glider was found dead in poor body condition. Histologically, large numbers of zoites were seen predominantly in macrophages in the liver, spleen and lung, with protozoal cysts present in the liver. Molecular and phylogenetic analyses inferred that the protozoan parasite belongs to the family Sarcocystidae and is closely related to previously identified apicomplexans found in yellow-bellied gliders (Petaurus australis) in Australia and southern mouse opossums (Thylamys elegans) in Chile., Graphical abstract Image 1, Highlights • A novel apicomplexan parasite caused a disseminated fatal disease in a wild feathertail glider. • The apicomplexan parasite is a member of the family Sarcocystidae. • It is most closely related to parasites previously identified in yellow-bellied gliders in Australia and southern mouseopossums in Chile.

In a class of holographic models for cosmology, the dual theory is given by a massless super-renormalisable QFT in 3 dimensions. In order to obtain cosmological observables, correlators of this QFT may be obtained via lattice field theory. Previous work has focused on scalar $\phi^4$ matrix theories in the adjoint representation of SU(N). In this work we present preliminary results in the critical behaviour and phase structure of the theory with an SU(N) scalar field coupled to gauge fields by utilising the Heatbath-Overrelaxation (HBOR) algorithm in lattice field theory.

A nonperturbative determination of the energy-momentum tensor is essential for understanding the physics of strongly coupled systems. The ability of the Wilson flow to eliminate divergent contact terms makes it a practical method for renormalizing the energy-momentum tensor on the lattice. In this paper, we utilize the Wilson flow to define a procedure to renormalize the energy-momentum tensor for a three-dimensional massless scalar field in the adjoint of $SU(N)$ with a $\varphi^4$ interaction on the lattice. In this theory the energy-momentum tensor can mix with $\varphi^2$ and we present numerical results for the mixing coefficient for the $N=2$ theory., Comment: 29 pages, 9 figures

IntroductionThe social media activity of some healthcare students has created doubt about their ability to uphold and defend the ethical principles of healthcare in their online behaviours. A lot of research has been conducted on the online behaviours of medical and allied health professional students, however, less has been undertaken on dental students.AimsThe aim was to determine whether students were aware of the guidelines set by the General Dental Council (GDC) regarding social media and whether they believed they were being professional in their online activities.Methods and materialsEighty-eight dental students (46 from year 2; 42 from year 4) at one UK dental school completed a questionnaire study examining their attitude towards and perceptions of e-professionalism.ResultsThe results show that most students were heavy users of social media with an awareness of social media guidelines set out by the GDC. However, student responses to various e-professionalism scenarios reveals disagreement on whether posts referring to alcohol and work colleagues were deemed unprofessional.ConclusionStudent perceptions of and attitudes towards e-professionalism is complicated and contradictory. More research will need to be undertaken to explore how we can inculcate e-professional values and behaviours in dental professionalism teaching.

This chapter explores how an extra-curricular approach to enabling interdisciplinary collaboration at The University of Huddersfield has helped music technology undergraduates to become enterprising. It explains the format of a collaboration hub (referred to as CollabHub), and following a brief overview of the key concepts that informed this initiative it provides examples that begin to illustrate how we can recognise risk taking, creativity and enterprise in this assessment-free setting. The CollabHub presents a continually evolving context for collaborative play, which is starting to build a community of apprenticeship. It is framed by research that has what David Hargreaves described as a social agenda for examining collaborative creativity in music. Looking ahead, this work considers how we may begin recognising and rewarding enterprise in this kind of extra-curricular context. Considering these themes and the broader implications for creative practice within and beyond a HMEI, it raises implications questions that may guide new research on extra-curricular collaborative play and enterprise development in HMEIs.
