POISSON STRUCTURE OF THE THREE-DIMENSIONAL EULER EQUATIONS IN FOURIER SPACE
We derive a simple Poisson structure in the space of Fourier modes for thevorticity formulation of the Euler equations on a three-dimensional periodic domain.This allows us to analyse the structure of the Euler equations using a Hamiltonianframework. The Poisson structure is valid on the divergence free subspace only, andwe show that using a projection operator it can be extended to be valid in the fullspace. We then restrict the simple Poisson structure to the divergence-free subspaceon which the dynamics of the Euler equations take place, reducing the size of thesystem of ODEs by a third. The projected and the restricted Poisson structures areshown to have the helicity as a Casimir invariant. We conclude by showing thatperiodic shearows in three dimensions are equilibria that correspond to singularpoints of the projected Poisson structure, and hence that the usual approach to studytheir nonlinear stability through the Energy-Casimir method fails.</p
A mobile ecology of resources for Covid-19 learning
Mobile devices and a vast array of accompanying applications offer significant affordances to create, consume, share, collaborate and communicateâaffordances that could be easily leveraged to facilitate meaningful learning. A positive disruption arising from Covid-19 that aligns with the affordances of mobile learning is the uncoupling of time and space in the learning process. Traditionally formal learning is a process that is predominately viewed as an experience that is âtimetabledââ scheduled to eventuate at a âplaceââlecture or a tutorial (or similar) in a room or lecture theatre. In this concise paper, an ecology of resources is discussed along with guiding principles for designing and facilitating uncoupled authentic and student-determined learning post the emergency remote teaching phase

Alichur Dome, South Pamir, Western India-Asia Collisional Zone: Detailing the Neogene Shakhdara-Alichur Syn-collisional Gneiss-Dome Complex and Connection to Lithospheric Processes
Neogene, synâcollisional extensional exhumation of Asian lowerâmiddle crust produced the ShakhdaraâAlichur gneissâdome complex in the South Pamir. The <1 kmâthick, myloniticâbrittle, topâNNE, normalâsense Alichur shear zone (ASZ) bounds the 125 Ă 25 km Alichur dome to the north. The Shakhdara dome is bounded by the <4 kmâthick, myloniticâbrittle, topâSSE South Pamir normalâsense shear zone (SPSZ) to the south, and the dextral Gunt wrench zone to its north. The Alichur dome comprises Cretaceous granitoids/gneisses cut by early Miocene leucogranites; its hanging wall contains non/weakly metamorphosed rocks. The 22â17 Ma Alichurâdomeâinjectionâcomplex leucogranites transition from foliationâparallel, centimeterâ to meterâthick sheets within the ASZ into discordant intrusions that may comprise half the volume of the dome core. Secondary fluid inclusions in mylonites and mylonitizationâtemperature constraints suggest Alichurâdome exhumation from 10â15 km depth. Thermochronologic dates bracket footwall cooling between ~410â130 °C from ~16â4 Ma; tectonic cooling/exhumation rates (~42 °C/Myr, ~1.1 km/Myr) contrast with erosionâdominated rates in the hanging wall (~2 °C/Myr, <0.1 km/Myr). Domeâscale boudinage, oblique divergence of the ASZ and SPSZ hanging walls, and dextral wrenching reflect minor approximately EâW material flow out of the orogen. We attribute broadly southward younging extensional exhumation across the central South Pamir between ~20â4 Ma to: (i) Mostly northward, forelandâdirected flow of hot crust into a cold foreland during the growth of the Pamir orocline; and (ii) Contrasting effects of basal shear related to underthrusting Indian lithosphere, enhancing extension in the underthrust South Pamir and inhibiting extension in the nonâunderthrust Central Pamir

The biomechanics of amnion rupture: an X-ray diffraction study
Pre-term birth is the leading cause of perinatal and neonatal mortality, 40% of which are attributed to the pre-term premature rupture of amnion. Rupture of amnion is thought to be associated with a corresponding decrease in the extracellular collagen content and/or increase in collagenase activity. However, there is very little information concerning the detailed organisation of fibrillar collagen in amnion and how this might influence rupture. Here we identify a loss of lattice like arrangement in collagen organisation from areas near to the rupture site, and present a 9% increase in fibril spacing and a 50% decrease in fibrillar organisation using quantitative measurements gained by transmission electron microscopy and the novel application of synchrotron X-ray diffraction. These data provide an accurate insight into the biomechanical process of amnion rupture and highlight X-ray diffraction as a new and powerful tool in our understanding of this process
'Reading landscape' : interdisciplinary approaches to understanding place
<p>This paper outlines a collaborative project between a group of Fine Art and Geography students who helped develop and contribute to a conversation about recording âplaceâ. Introducing methodologies from both disciplines, the project started from the premise of all environmental ârecordingsâ being âinputsâ and so questioned what could be defined as âdataâ when encountering a location. Brunelâs Grand Entrance to the Thames Tunnel (London) provided the motivation for 10 objective and subjective ârecordingsâ which were subsequently distilled into a smaller subset and then used to produce a short film that was presented at an international conference. Important to the collaborative nature of the project were ongoing opportunities to share equipment, techniques, material and references across disciplines. It was an experiment to measure the potential for âmappingâ to capture physical and historical information, as well as embodied experience.</p
