Emergent Criticality and Friedan Scaling in a 2D Frustrated Heisenberg Antiferromagnet

description: We study a two-dimensional frustrated Heisenberg antiferromagnet on the windmill lattice consisting of triangular and dual honeycomb lattice sites. In the classical ground state the spins on different sublattices are decoupled, but quantum and thermal fluctuations drive the system into a coplanar state via an "order from disorder" mechanism. We obtain the finite temperature phase diagram using renormalization group approaches. In the coplanar regime, the relative U$(1)$ phase between the spins on the two sublattices decouples from the remaining degrees of freedom, and is described by a six-state clock model with an emergent critical phase. At lower temperatures the system enters a $\mathbb{Z}_6$ broken phase with long-range phase correlations. We derive these results by two distinct renormalization group approaches to two-dimensional magnetism: by Wilson-Polyakov scaling and by Friedan's geometric approach to nonlinear sigma models where the scaling of the spin-stiffnesses is governed by the Ricci flow of a 4D metric tensor.

description: Combining the characteristic method and the local discontinuous Galerkin method with carefully constructing numerical fluxes, we design the variational formulations for the time-dependent convection-dominated Navier-Stokes equations in $\mathbb{R}^2$. The proposed symmetric variational formulation is strictly proved to be unconditionally stable; and the scheme has the striking benefit that the conditional number of the matrix of the corresponding matrix equation does not increase with the refining of the meshes. The presented scheme works well for a wide range of Reynolds numbers, e.g., the scheme still has good error convergence when $Re=0.5 e+005$ or $1.0 e+ 008$. Extensive numerical experiments are performed to show the optimal convergence orders and the contours of the solutions of the equation with given initial and boundary conditions.

description: To tackle the domain specific challenges spacecraft operations poses on anomaly detection methods, the Automated Telemetry Health Monitoring System (ATHMoS) was developed at the German Space Operations Center (GSOC) and integrated into our Visualisation and Data Analysis software (ViDA). The main challenges include the peculiarities of the telemetry data transmitted by the satellites, the limitation of resources and accuracy and usability requirements posed by the end users. The ATHMoS was designed with these challenges in mind and uses sets of generic statistical properties to derive an explainable anomaly probability.

description: Flight control clearance and flight envelope certification are vital steps for guaranteeing flight safety. While there exist numerical techniques for flight dynamics analysis, these tend to be limited in their predictive capabilities given their dependence to either linearized system dynamics or their conservativeness. This paper proposes a new method contributing to the roadmap toward flight certification that expands the safe flight envelope by incorporating multiple Shape Functions within the sum-of-squares optimization framework. The technique, formulated using polynomial Lyapunov functions, ensures controller stability and performance. The proposed approach achieves a larger region of attraction estimation. The method is validated via the estimation of a region of attraction for closed-loop polynomial dynamics of the Vought F-8 Crusader aircraft. The effectiveness of the method is demonstrated through extensive simulations, illustrating its applicability in flight control system analysis and providing an expanded safe, and stable operating region. The enhanced region of attraction offers improved operational flexibility, as well as safety margins and system performance.

description: The Triangular, NACA 0012-34 and Ishii airfoils have been selected for the compressible low-Reynolds aerodynamics in Martian atmosphere. All respect shape characteristics suggested in literature, delivering high aerodynamic performance in a low-Reynolds number region. The CIRA in-house developed code UZEN has been applied by employing several turbulence models to carry out the analysis on the three selected airfoils. Numerical results are globally in good agreement with experimental data in terms of aerodynamic coefficients. The complex flow field around the airfoils has been discretely reproduced. Further investigations seem to indicate that increasing Mach number does not critically affect the flow field.
What can schools do? Knowledge, social identities and the changing world.

description: This is an inaugural lecture presented at the University of Melbourne when that university, an old and prestigious one, recently set up its first Chair of Curriculum in 2005. Lyn Yates argues in the lecture that curriculum is both a complex, challenging and highly intellectual endeavour and a necessarily practical, political and pragmatic endeavour. She discusses ways in which impossible expectations are set up for schools and for education scholars, and argues the need to attend to both the big picture issues about how the world is changing, and the more specific issues of the personal, and the need to manage the selective and competitive characteristics of schooling as a system, as well as questions about learning and knowledge and the development of individual students. In illustrating her themes, Yates draws on her three major recent research projects: the 12 to 18 Project (on gender, change and school inequalities); the Effects project (on new technology in schools); and the Changing Work, Changing Workers, Changing Selves project (on pedagogies of the new vocationalism).

description: This paper analyses the comprehensive cryogenic propellant management challenges in low gravity that may be used to model an in-orbit cryogenic propellant depot for space exploration in the future. This research presents a framework that enables analysis of novel propellant in the depot at the preliminary case to understand the problems associated with different subsystems of the space depot, such as the Supply Tank, Transfer Lines, and Receiver Tank, due to various parameters discussed such as gas-free removal of liquid, phase separation, boil-off, heat transfer, chill down, no-vent filling, and so on. Environmental problems resulting from the depot\'s location are also stated. In addition to this, mitigation techniques to counter the problems as mentioned earlier are also discussed, which can be considered, such as using active and passive cooling techniques.

description: A quasiplane $f(V)$ is the image of an $n$-dimensional Euclidean subspace $V$ of ${\Bbb R}^N$ ($1\leq n\leq N-1$) under a quasiconformal map $f:{\Bbb R}^N\to{\Bbb R}^N$ . We give sufficient conditions in terms of the weak quasisymmetry constant of the underlying map for a quasiplane to be a bi-Lipschitz $n$-manifold and for a quasiplane to have big pieces of bi-Lipschitz images of ${\Bbb R}^n$. One main novelty of these results is that we analyze quasiplanes in arbitrary codimension $N-n$. To establish the big pieces criterion, we prove new extension theorems for "almost affine" maps, which are of independent interest. This work is related to investigations by Tukia and Väisälä on extensions of quasisymmetric maps with small distortion.

description: The single-winged seed, known as a samara, uses autorotation to disperse seeds. The aerodynamic coefficient for the samras is required for modelling and understanding its performance. Experimental studies using Particle Image Velocimetry (PIV) were conducted in a vertical wind tunnel, examining a flat plate aerofoil with t/c = 0.1, Reynolds numbers of 1218 -3654, and angles of attack from 0 -90similar to samaras. Flow separation occurred at low angles, while moderate angles displayed leading-edge vortex shedding. At high angles, Karman vortex street type of shedding was observed. The computed drag coefficient using control volume analysis aligned with literature, except for specific angles, necessitating further experiments to comprehend variations.

Investigating the Role of Testing in Long-Term Learning of visuo-spatial Arrays

Publisher: name: Open Science Framework
Year: 2022
Subjects: subject: Social and Behavioral Sciences

description: One of the best studied effects for showing a contribution of long-term memory (LTM) to performance on working memory (WM) tasks is the Hebb effect (Hebb, 1961). The Hebb effect refers to the finding that when in a series of trials of immediate serial recall one list is repeated occasionally, performance on that list improves across repetitions compared to non-repeated filler lists. This finding has been demonstrated with a broad range of materials, including digits, words, spatial locations and faces (Horton et al., 2008; Page et al., 2013; Sukegawa et al., 2019). However, there are several studies in the domain of visual and spatial memory which failed to replicate the Hebb effect after many repetitions of the same visual array (Fukuda & Vogel, 2019; Logie et al., 2009; Olson & Jiang, 2004). In a yet unpublished study, Souza & Oberauer (2018) systematically investigated the differences between studies consistently replicating the Hebb effect and studies failing to find this effect for visual arrays. Across four main differences between these studies (short vs. long presentation times of items, sequential vs. simultaneous presentation of items, test of all items vs. test of only one item and test in consistent forward order vs. test in random order) they identified the number of tested items in the WM test as the cruical variable for generating the Hebb effect with visual arrays: The Hebb effect emerged only if all items of an array were tested in the WM memory test. This finding points to an important role of testing for forming LTM traces of visual arrays. However, it remains unclear if no LTM trace is formed when only one item is tested, or whether the test of a single item does not provide enough opportunity to use an existing LTM trace or whether there is a combination of both. The aim of the present study is to distinguish between these possible explanations for the absence of Hebb learning when only one item in a visual array is tested.

The sub-Doppler spectral lines are the consequence of saturated absorption where the incident laser beam saturates the atomic medium and the back-scattered light probes it. Some specificities of the observed spectra reflect the transient atomic evolution under confinement inside the pores. Simplicity, robustness and potential miniaturization are appealing features of this system as a spectroscopic reference.

description: Optomechanical detectors have reached the standard quantum limit in position and force sensing where measurement backaction noise starts to be the limiting factor for the sensitivity. A strategy to circumvent measurement backaction, and surpass the standard quantum limit, has been suggested by M. Tsang and C. Caves in Phys. Rev. Lett. 105 123601 (2010). We provide a detailed analysis of this method and assess its benefits, requirements, and limitations. We conclude that a proof-of-principle demonstration based on a micro-optomechanical system is demanding, but possible. However, for parameters relevant to gravitational wave detectors the requirements for backaction evasion appear to be prohibitive.

description: Postcolonial, transnational curriculum should value the experiences and knowledge of everyday lives, understanding the space of “interlanguage and intercultural differences” (Aoki, 2003, p. 6). Elsewhere in this issue, William Pinar says of Ted Aoki, “He is questing (rather than questioning) for the ‘original ground of curriculum as a human study’”. The focus of my writing is on language in a socio-cultural context. It amazes me how much everyday life and language are interwoven, especially that language which is unspeakable or untranslatable. During the summer of 2004, I returned to Japan to visit family and attend my fifty-year class reunion, which gave me the opportunity to revisit and reflect on the past and present. Like Hongyu Wang (2004) revisiting Beijing, I felt estranged from my homeland. Asanuma (1999) says, “Meaning is created out of the knowledge of past experiences and one’s interaction with others” (p.23). The idea that our lives are composed not only of major events but the countless little events intrigued me and I could not help but keep note of them. This paper describes my struggle from the in-between spaces of insider/outsider, in multiple re-writings of tangled memories. I recorded the day-to-day happenings in a diary. I drew on the poetic discourse of Haiku as I felt that diary entries, alone, would inadequately convey the deep-felt emotions in these moments. A poetic discourse of the mundane of everyday life “seikatsu tsuzurikata” (daily diary) becomes an invocation for “questing” in-between languages and cultures. 要旨 戦後の国家を超えたカリキュラムは“内なる言語や内なる文化”(Aoki,2003. p.6)の違うスペースを理解して日々の経験や知識を高く評価するべきです。ウィィアム-パイナーはテッドアオキはカリキュラムの土台は人間探求ではないかと質問をなげかけているというより、人間探求であってほしいと懇願していると言っています。社会的、文化的な側面から言葉に焦点をあててみました。いかに毎日使う言葉が生活の中に織り込まれていて、英語に翻訳できない、言葉にできない言葉があることは驚きでした。2004年の夏に日本に住む家族に会うためと小学校の50年ぶりの同窓会に出席するために日本にもどりました。過去と現在を反省する機会を与えられました。ホンギューワン(2004)が北京に戻った時と同じように私も故国に何か隔たりを感じました。浅沼茂先生は物事の意味する所は他の人との相互の影響とか過去の経験から来る知識によってつくられると言っています。私達の生活は大きな事柄だけでなく日々の無数の小さな事柄に触発されます。このペイパーで読者と一緒にインサイダーとアウトサイダーの狭間で起こる私の苦しみを、絡み合った記憶をほどきながら、書き直しながら分け合いたいと思います。毎日の事柄を書きながらどうしてもうまく表現できないもどかしさを俳句にたくしました。生活綴り方の中に盛り込んだ詩的な要素が言葉と文化の仲介者となることを祈りを込めて願います

description: This article addresses the weak convergence of numerical methods for Brownian dynamics. Typical analyses of numerical methods for stochastic differential equations focus on properties such as the weak order which estimates the asymptotic (stepsize $h \to 0$) convergence behavior of the error of finite time averages. Recently it has been demonstrated, by study of Fokker-Planck operators, that a non-Markovian numerical method [Leimkuhler and Matthews, 2013; Leimkuhler et al., 2013] generates approximations in the long time limit with higher accuracy order (2nd order) than would be expected from its weak convergence analysis (finite-time averages are 1st order accurate). In this article we describe the transition from the transient to the steady-state regime of this numerical method by estimating the time-dependency of the coefficients in an asymptotic expansion for the weak error, demonstrating that the convergence to 2nd order is exponentially rapid in time. Moreover, we provide numerical tests of the theory, including comparisons of the efficiencies of the Euler-Maruyama method, the popular 2nd order Heun method, and the non-Markovian method.

description: Byproducts generated during jackfruit processing that mainly consists of rind, strand, core, and seeds were analyzed for their composition. It was found that jackfruit is rich in fiber content (highest in core part, 32%) and a good source of protein (highest in seed part, 15%). Different parts possess appreciable functional properties, which give an advantage of being used in bakery products. For a desirable flatbread, the jackfruit and wheat flour formulations were made using D-optimal mixture design. It demonstrated that the dough springiness, flatbread color, flatbread overall acceptability, and shear force varied significantly with respect to the incorporation of flour of different parts of jackfruit in wheat for the formulation of flatbread. The results indicate that the replacement of the jackfruit flour in flatbread is highly nutritious at the same time stays acceptable.

description: This article applies William Doll's postmodern perspective on curriculum to the education of the author's 4-year-old niece. It is written as a letter to the child's mother (the author's sister) and thus offers an interpretation of the applicability of Doll's theory to education in the People's Republic of China. The article begins by introducing some key concepts in theorizing a postmodernist curriculum and draws attention to the differences between a modernist curriculum and a postmodernist curriculum. The article then examines Doll's 4R's (richness, recursion, relations, and rigor), with particular reference to their implications for Chinese education, and their patterns (in ambiguity, webbing and play) when understood as a whole. The article concludes with the author's reflections on how postmodernist curriculum theorizing has influenced her personal worldview.

description: Two texts running a chiasmatic course – running with and against lines of separation. Traces of Bergamo 1999 linger in these textured doublings invoked by an invitation to Baton Rouge and a dialogue of international curricular provocations from which IAACS emerged. We query what happens when teachers and learners locate themselves in spaces where languages invoke a re-articulation of their pedagogic lives. Incited by such cadences of ar/rhythmic moments, we write out of a living pedagogy that is always already in-between movements of translation and transformation. Re-running the course – the course of running with and against our work – we have learned to read with Aoki that the same is always already – toujours déjà – the same and not the same. And hence our laboured breathing…running with and against internationalizing texts of currere.

description: This study aims to evaluate the relationship between the physicochemical characteristics and sensorial profile of a plant-based beverage. The beverages were classified as hypotonic (cashew nut, oat, and soybean beverages) and isotonic (rice and spelt grain beverages). The spelt grain and cashew nut beverages presented a higher content of particles with flocculation and higher sedimentation values. The viscosity of the beverages varied from 5.0–16.8 mPa.s. The viscosity and color attributes in the sensorial analysis were considered “about-right” or “much-more-than-ideal” by over 50% of the judges for the soybean (81 judges for both viscosity and color, respectively) and oat (65 and 69, respectively) beverages. The highest acceptability index for the flavor attribute was found for the soybean beverage, which was the most preferred beverage (p < .01).

description: We report the synthesis and characterization of Li2ZnV3O8, which is a new Zn-doped LiV2O4 system containing only tetravalent vanadium. A Curie-Weiss susceptibility with a Curie-Weiss temperature of CW ~214 K suggests the presence of strong antiferromagnetic correlations in this system. We have observed a splitting between the zero-field cooled ZFC and field cooled FC susceptibility curves below 6 K. A peak is present in the ZFC curve around 3.5 K suggestive of spin-freezing . Similarly, a broad hump is also seen in the inferred magnetic heat capacity around 9 K. The consequent entropy change is only about 8% of the value expected for an ordered S = 1=2 system. This reduction indicates continued presence of large disorder in the system in spite of the large CW, which might result from strong geometric frustration in the system. We did not find any temperature T dependence in our 7Li nuclear magnetic resonance NMR shift down to 6 K (an abrupt change in the shift takes place below 6 K) though considerable T-dependence has been found in literature for LiV2O4- undoped or with other Zn/Ti contents. Consistent with the above observation, the 7Li nuclear spin-lattice relaxation rate 1/T1 is relatively small and nearly T-independent except a small increase close to the freezing temperature, once again, small compared to undoped or 10% Zn or 20% Ti-doped LiV2O4.

description: We find that the recently introduced model of self-trapping supported by a spatially growing strength of a repulsive nonlinearity gives rise to robust vortex-soliton tori, i.e., three-dimensional vortex solitons, with topological charges S. The family with S=1 is completely stable, while the one with S=2 has alternating regions of stability and instability. The families are nearly exactly reproduced in an analytical form by the Thomas-Fermi approximation (TFA). Unstable states with S=2 and 3 split into persistently rotating pairs or triangles of unitary vortices. Application of a moderate torque to the vortex torus initiates a persistent precession mode, with the torus' axle moving along a conical surface. A strong torque heavily deforms the vortex solitons, but, nonetheless, they restore themselves with the axle oriented according to the vectorial addition of angular momenta.

Editorial: A vision for transnational curriculum inquiry
Creators: name: Gough, Noel
Publisher: name: TCI (Transnational Curriculum Inquiry)

description: This essay presents the foundation Editor's vision for Transnational Curriculum Inquiry (TCI), the journal of the International Association for the Advancement of Curriculum Studies (IAACS). It explores some theoretical and practical possibilities for building new transnational and transcultural solidarities in postcolonial curriculum inquiry and argues that building such solidarities requires a rethinking of the ways in which we perform and represent curriculum inquiry, so that curriculum work within a global knowledge economy does not merely assimilate national (local) curriculum discourses-practices into an imperial (global) archive.

description: The plural features of society can be perceived in education through the analysis of school curricula. This paper analyses curricula from three Latin American countries with different links between State and Religion: Argentina constitution refers Catholicism has its official religion; Brazil assumes secularism officially but there is considerable religion influence on the State affairs; Uruguay has a higher consolidated secularism. The controversial theme of biological evolution was analysed in secondary school biology curricula of these three countries. To achieve this goal, school national programmes, syllabi and other related documents from each country were analysed. Results showed that curricula provide modern approaches with regard to the teaching of biological evolution. Argentina and Brazil have decentralizing policies set up by their Federal Ministry of Education in which the 23 Provinces (in Argentina) and the 26 States (in Brazil) define their specific curriculum contents. This system leads to differences between more conservative Provinces/States where biological evolution can be absent and more liberal Provinces/States where biological evolution is present. Uruguay highlights biological evolution explicitly in its national curriculum, possibly because of its solid secularism. From overall findings, it can be concluded that State secularism may influence the design of the biology curriculum, particularly in controversial matters, as biological evolution.

description: We present a practical high-speed quantum random number generator, where the timing of single-photon detection relative to an external time reference is measured as the raw data. The bias of the raw data can be substantially reduced compared with the previous realizations. The raw random bit rate of our generator can reach 109 Mbps. We develop a model for the generator and evaluate the min-entropy of the raw data. Toeplitz matrix hashing is applied for randomness extraction, after which the final random bits are able to pass the standard randomness tests.

description: We present results for entropy and kinetic energy spectra computed from direct numerical simulations for low-Prandtl-number ($Pr < 1$) turbulent flow in Rayleigh-Bénard convection with uniform rotation about a vertical axis. The simulations are performed in a three-dimensional periodic box for a range of Taylor number ($ 0 \leq Ta \leq 10^8$) and reduced Rayleigh number $r = Ra/Ra_{\circ} (Ta, Pr)$ ($1.0 \times 10^2 \le r \le 5.0 \times 10^3$). The Rossby number $Ro$ varies in the range $1.34 \le Ro \le 73$. The entropy spectrum $E_θ(k)$ shows bi-splitting into two branches for lower values of wave number $k$. The entropy in the lower branch scales with $k$ as $k^{-1.4\pm 0.1}$ for $r > 10^3$ for the rotation rates considered here. The entropy in the upper branch also shows scaling behavior with $k$, but the scaling exponent decreases with increasing $Ta$ for all $r$. The energy spectrum $E_v(k)$ is also found to scale with the wave number $k$ as $k^{-1.4\pm 0.1}$ for $r > 10^3$. The scaling exponent for the energy spectrum and the lower branch of the entropy spectrum vary between $-1.7$ to $-2.4$ for lower values of $r$ ($< 10^3$). We also provide some simple arguments based on the variation of the Kolmogorov picture to support the results of simulations.

title: Capital’s commune: the rise of co-living in the financialised city
Creators: name: White, Tim
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2025

description: This thesis examines a pivotal response to the intensifying housing crises facing major cities: the rise of co-living. Co-living is for-profit, privately-managed and delivered shared housing. It is characterised by a combination of small private units, flexible rental contracts, and communal spaces and amenities. Over the past decade, co-living has emerged as a financialised real estate sector attracting significant capital flows. The rise of co-living raises questions that get to the very heart of key issues confronting housing and cities today, from the growing influence of global corporate landlords, to the restructuring of economies around assets and rents, to the rise of platform capitalism and ‘gig economy’ labour relations. Focusing on the proliferation of the sector across European and North American cities, this thesis takes a critical lens to the co-living phenomenon, examining what is driving it, what it is like to live in the spaces, and what it can tell us about urban residential change under financialised capitalism more generally. Drawing on interviews with industry professionals and residents, participant observation at real estate events, analysis of corpus material and auto-ethnography in co-living spaces, the thesis details the complex and contradictory role played by co-living in contemporary housing systems. It is a form of corporate landlordism that extends the rent-generating capacity of residential space and extracts market opportunities from precarity. The sector is a site of intense experimentation with platform business strategies, seeking to optimise and capture new forms of value from the housing process. At the same time, co-living offers a way for privileged, mobile individuals to flexibly traverse different locations in pursuit of opportunities—including for social connection. In all, the thesis demonstrates how co-living is a product of, and feeds into, the inequalities of the financialised city.
High-resolution imaging of $Kepler$ planet host candidates. A comprehensive comparison of different techniques

description: The Kepler mission has discovered thousands of planet candidates. Currently, some of them have already been discarded; more than 200 have been confirmed by follow-up observations, and several hundreds have been validated. However, most of them are still awaiting for confirmation. Thus, priorities (in terms of the probability of the candidate being a real planet) must be established for subsequent observations. The motivation of this work is to provide a set of isolated (good) host candidates to be further tested by other techniques. We identify close companions of the candidates that could have contaminated the light curve of the planet host. We used the AstraLux North instrument located at the 2.2 m telescope in the Calar Alto Observatory to obtain diffraction-limited images of 174 Kepler objects of interest. The lucky-imaging technique used in this work is compared to other AO and speckle imaging observations of Kepler planet host candidates. We define a new parameter, the blended source confidence level (BSC), to assess the probability of an object to have blended non-detected eclipsing binaries capable of producing the detected transit. We find that 67.2% of the observed Kepler hosts are isolated within our detectability limits, and 32.8% have at least one visual companion at angular separations below 6 arcsec. We find close companions (below 3 arcsec) for the 17.2% of the sample. The planet properties of this sample of non-isolated hosts are revised. We report one possible S-type binary (KOI-3158). We also report three possible false positives (KOIs 1230.01, 3649.01, and 3886.01) due to the presence of close companions. The BSC parameter is calculated for all the isolated targets and compared to both the value prior to any high-resolution image and, when possible, to observations from previous high-spatial resolution surveys in the Kepler sample.

description: A single static magnetic impurity in a fully-gapped superconductor leads to formation of an intragap quasiparticle bound state. At temperatures much below the superconducting transition, the energy relaxation and spin dephasing of the state are expected to be exponentially suppressed. The presence of such a state can be detected in electron tunneling experiments as a pair of conductance peaks at positive and negative biases. Here we show, that for an arbitrarily weak tunneling strength, the peaks have to be symmetric with respect to the applied bias. This is in contrast to the standard result that the tunneling conductance is proportional to the local (in general particle-hole asymmetric) density of states. The asymmetry can be recovered is one allows for either a finite density of impurity states, or that impurities are coupled to another, non-superconducting, equilibrium bath.
