description: This paper is to evaluate certain Catalan-Hankel Pfaffians by the theory of skew orthogonal polynomials. Due to different kinds of hypergeometric orthogonal polynomials underlying the Askey scheme, we explicitly construct the classical skew orthogonal polynomials and then give different examples of Catalan-Hankel Pfaffians with continuous and $q$-moment sequences.

description: Hard partons propagating through hot and dense matter loose energy, leading to the observed depletion of hard hadron spectra in nucleus nucleus collision as compared to scaled proton proton collisions. This lost energy has to reappear in the medium due to the conservation of energy. Apart from heating the medium, there is the possibility that a propagating collective mode is excited. We outline a formalism that can be used to track the propagation of such a mode through the evolving medium if its dispersion relation is known and to calculate the resulting distortion of hadronic spectra at freeze-out. Using this formalism, we demonstrate within a detailed picture of the evolution of the expanding system and the experimental trigger conditions that the assumption of a sound mode being excited is in line with 2-particle correlation measurements by PHENIX and STAR for a semi-hard trigger. In this case, the measurement is sensitive to the averaged speed of sound in the hot matter. We also make suggestions how this sensitivity can be improved.

Quantum Field Theory on Curved Backgrounds, I. The Euclidean Functional Integral

Year: 2006
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We give a mathematical construction of Euclidean quantum field theory on certain curved backgrounds. We focus on generalizing Osterwalder-Schrader quantization, as these methods have proved useful to establish estimates for interacting fields on flat space-times. In this picture, a static Killing vector generates translations in Euclidean time, and physical positivity is played by positivity under reflection of Euclidean time. We discuss the quantization of flows which correspond to classical space-time symmetries, and give a general set of conditions which imply that broad classes of operators in the classical picture give rise to well-defined operators on the quantum-field Hilbert space. In particular, Killing fields on spatial sections give rise to unitary groups on the quantum-field Hilbert space, and corresponding densely-defined self-adjoint generators. We construct the Schrödinger representation using a method which involves localizing certain integrals over the full manifold to integrals over a codimension-one submanifold. This method is called sharp-time localization, and implies reflection positivity.

Year: 2019

description: This small case-study discusses a specific science teaching strategy that has been developed through a multimodal and socio-semiotic lens while drawing on embodied cognition as a pedagogical tool for designing a learning journey to engage students in learning about electric circuits. I have worked with pre-service teachers (PSTs) to use this strategy in their classroom to allow their students to use different senses and modes of communication to engage in knowledge acquisition. The use of movement, sound, imagery and other resources is then linked with real objects and tasks in the science classroom. This type of pedagogical strategy has potential implications for sciences teaching and learning which are explored in this piece. I draw on self-reported answers and semi-structured interviews with PSTs and other former PSTs from our institution who have used this strategy in real classrooms environments. Results show that this strategy has had important impact on PSTs’ perceptions about teaching and learning and pedagogical understanding, as well as achieving a more meaningful engagement of students during and after the lesson, in particular if the teacher is also actively involved in doing the task with the students.
Gaining insights on anyon condensation and 1-form symmetry breaking across a topological phase transition in a deformed toric code model

description: We examine the condensation and confinement mechanisms exhibited by a deformed toric code model proposed in [Castelnovo and Chamon, Phys. Rev. B, 2008]. The model describes both sides of a phase transition from a topological phase to a trivial phase. Our findings reveal an unconventional confinement mechanism that governs the behavior of the toric code excitations within the trivial phase. Specifically, the confined magnetic charge can still be displaced without any energy cost, albeit only via the application of non-unitary operators that reduce the norm of the state. This peculiar phenomenon can be attributed to a previously known feature of the model: it maintains the non-trivial ground state degeneracy of the toric code throughout the transition. We describe how this degeneracy arises in both phases in terms of spontaneous symmetry breaking of a generalized (1-form) symmetry and explain why such symmetry breaking is compatible with the trivial phase. The present study implies the existence of subtle considerations that must be addressed in the context of recently posited connections between topological phases and broken higher-form symmetries.

Year: 2019

description: The aims of this study are to investigate the impact of a ‘non-traditional’ extracurricular club on pupils’ participation in physical activity, and what motivated pupils to attend. This action research intervention was carried out within a Greater London secondary school for girls, for four weeks during lunchtimes. To conduct the intervention, a dodgeball club was introduced as an extracurricular club, which was open to pupils in Key Stage 3. Pupils’ attendance was monitored and some were asked to complete the Motives for Physical Activity Measure (MPAM-R), at the end of the intervention. The findings indicate that the intervention had a positive impact within its environment, as an increase in pupils’ participation was observed over the course of the study. Additionally, the interest/enjoyment of the club was recorded as the highest motivation for participation.

New Teachers and Practitioner Research: Willing; Able; Irrelevant
Creators: name: Ayres, D.
Publisher: name: The School of Education and Communities, University of East London
Year: 2019

description: This article presents some of the key findings of a mixed-method exploratory case study investigating the perceptions and realities of new teachers’ engagement in and with research. Newly qualified teachers are well prepared to engage with research literature for the development of practice, and to employ the research skills which they develop during their undergraduate degrees and their initial training programmes. In school, their research knowledge and skills are seldom put to good use, however. Should initial teacher education therefore abandon research methods modules and focus on developing the skills which enable new teachers to access and critically evaluate existing research evidence? The study employed a hybrid analytical framework (Fereday & Muir-Cochrane 2006), a three-stage process of inductive and deductive theme-generation and scrutiny.

Fluence Adaptation for Task-based Dose Optimization in X-ray Phase-Contrast Imaging

description: Purpose: Grating-based imaging (GBI) and edge-illumination (EI) are two promising types of XPCI as the conventional x-ray sources can be directly utilized. For GBI and EI systems, the phase-stepping acquisition with multiple exposures at a constant fluence is usually adopted in the literature. This work, however, attempts to challenge such a constant fluence concept during the phase-stepping process and proposes a fluence adaptation mechanism for dose reduction. Method: Recently, analytic multi-order moment analysis has been proposed to improve the computing efficiency. In these algorithms, multiple contrasts can be calculated by summing together the weighted phase-stepping curves (PSCs) with some kernel functions, which suggests us that the raw data at different steps have different contributions for the noise in retrieved contrasts. Based on analytic retrieval formulas and the Gaussian noise model for detected signals, we derived an optimal adaptive fluence distribution, which is proportional to the absolute weighting kernel functions and the root of original sample PSCs acquired under the constant fluence. Results: To validate our analyses, simulations and experiments are conducted for GBI and EI systems. Simulated results demonstrate that the dose reduction ratio between our proposed fluence distributions and the typical constant one can be about 20% for the phase contrast, which is consistent with our theoretical predictions. Although the experimental noise reduction ratios are a little smaller than the theoretical ones, synthetic and real experiments both observe better noise performance by our proposed method. Our simulated results also give out the effective ranges of the parameters of the PSCs, such as the visibility in GBI, the standard deviation and the mean value in EI, providing a guidance for the use of our proposed approach in practice.

On generalized symmetric powers and a generalization of Kolmogorov-Gelfand-Buchstaber-Rees theory

description: The classical Kolmogorov-Gelfand theorem gives an embedding of a (compact Hausdorff) topological space X into the linear space of all linear functionals C(X)^* on the algebra of continuous functions C(X). The image is specified by algebraic equations: f(ab)=f(a)f(b) for all functions a, b on X; that is, the image consists of all algebra homomorphisms of C(X) to numbers. Buchstaber and Rees have found that not only X, but all symmetric powers of X can be embedded into the space C(X)^*. The embedding is again given by algebraic equations, but more complicated. Algebra homomorphisms are replaced by the so-called "n-homomorphisms", the notion that can be traced back to Frobenius, but which explicitly appeared in Buchstaber and Rees's works on multivalued groups. We give a further natural generalization of Kolmogorov-Gelfand-Buchstaber-Rees theory. Symmetric powers of a space X or of an algebra A are replaced by certain "generalized symmetric powers" Sym^{p|q}(X) and S^{p|q}A, which we introduce, and n-homomorphisms, by the new notion of "p|q-homomorphisms". Important tool of our study is a certain "characteristic function" R(f,a,z), which we introduce for an arbitrary linear map of algebras f, and whose functional properties with respect to the variable z reflect algebraic properties of the map f.

description: We study the impact of renormalization group effects on QCD axion phenomenology. Focusing on the DFSZ model, we argue that the relevance of running effects for the axion couplings crucially depends on the scale where the heavier Higgs scalars are integrated out. We study the impact of these effects on astrophysical and cosmological bounds as well as on the sensitivity of helioscopes experiments such as IAXO and XENONnT, showing that they can be sizable even in the most conservative case in which the two Higgs doublets remain as light as the TeV scale. We provide simple analytical expressions that accurately fit the numerical solutions of the renormalization group equations as a function of the mass scale of the heavy scalars.

Paying for Marketwide Services in Fluid Milk Markets

description: Excerpt from the report: Functions in marketing raw milk have shifted from processors to cooperatives in the past 25 years. The change has usually produced more efficient milk markets, but some cooperatives are not paid for the marketwide benefits of their services. These marketwide services are like public goods in that everyone gains from them with no restriction. Like all public goods, these services provide both public and private benefits. Balancing the milk supply, for example, for a number of processors provides them with a service that each would otherwise have to provide at a higher cost. It also supplies a public service of increased efficiency that individual processors could not provide. This report reviews marketwide services, issues surrounding them, and various ways to pay for them, a question of particular interest since the Food Security Act of 1985 has for the first time explicitly authorized Federal marketing order payments for such services.
Unity of Kohn-Sham Density Functional Theory and Reduced Density Matrix Functional Theory

description: This work presents a theory to unify the two independent theoretical frameworks of Kohn-Sham (KS) density functional theory (DFT) and reduced density matrix functional theory (RDMFT). The generalization of the KS orbitals to hypercomplex number systems leads to the hypercomplex KS (HCKS) theory, which extends the search space for the density in KS-DFT to a space that is equivalent to natural spin orbitals with fractional occupations in RDMFT. Thereby, HCKS is able to capture the multi-reference nature of strong correlation by dynamically varying fractional occupations. Moreover, the potential of HCKS to overcome the fundamental limitations of KS is verified on systems with strong correlation, including atoms of transition metals. As a promising alternative to the realization of DFT, HCKS opens up new possibilities for the development and application of DFT in the future.

description: One of the key noise sources that currently limits high-contrast imaging observations for exoplanet detection is quasi-static speckles. Quasi-static speckles originate from slowly evolving non-common path aberrations (NCPA). The purpose of this work is to present a proof-of-concept on-sky demonstration of spatial Linear Dark Field Control (LDFC). The ultimate goal of LDFC is to stabilize the point spread function (PSF) by addressing NCPA using the science image as additional wavefront sensor. We combined spatial LDFC with the Asymmetric Pupil vector-Apodizing Phase Plate (APvAPP) on the Subaru Coronagraphic Extreme Adaptive Optics system at the Subaru Telescope. In this paper, we report the results of the first successful proof-of-principle LDFC on-sky tests. We present results from two types of cases: (1) correction of instrumental errors and atmospheric residuals plus artificially induced static aberrations introduced on the deformable mirror and (2) correction of only atmospheric residuals and instrumental aberrations. When introducing artificial static wavefront aberrations on the DM, we find that LDFC can improve the raw contrast by a factor of $3$--$7$ over the dark hole. In these tests, the residual wavefront error decreased by $\sim$50 nm RMS, from $\sim$90 nm to $\sim40$ nm RMS. In the case with only residual atmospheric wavefront errors and instrumental aberrations, we show that LDFC is able to suppress evolving aberrations that have timescales of $<0.1$--$0.4$ Hz. We find that the power at $10^{-2}$ Hz is reduced by a factor of $\sim$20, 7, and 4 for spatial frequency bins at 2.5, 5.5, and 8.5 $λ/D$, respectively. The results presented in this work show that LDFC is a promising technique for enabling the high-contrast imaging goals of the upcoming generation of extremely large telescopes.

Modelling strategic information technology impact on inter-firm competition: pricing
Creators: name: Nault, Barrie R.
Publisher: name: University of British Columbia
Year: 2011

description: This research studies normative pricing strategies for information technology (IT) used by suppliers to supplement an underlying primary good. Transactions with consumers and customer firms are considered. Characteristics of IT are divided into IT impacts on customers, and IT impacts on suppliers. IT impacts on customers include vertical differentiation or reduced turnover costs for the primary good, and positive IT adoption costs. IT impacts on suppliers include reduced production costs for the primary good, and the costs of IT. Optimal pricing for the IT and the primary good is modelled for monopoly, and Bertrand competition based on IT and the primary good is modelled for oligopoly. Two part tariffs are used for the IT and IT enhanced primary good. Results of pricing to consumers show that the fixed component of an optimal (or equilibrium) two part tariff can either be a net tax or a net subsidy, confirming the possibility of taxed or subsidized IT adoption. For the monopolist offering the IT and IT enhanced primary good only, the consumer's adoption/switching cost limits the possible subsidy. Consistent with previous economics research, in a duopoly where one supplier has IT, the IT supplier abandons the original primary good. Two suppliers with identical IT cannot attain a positive profit equilibrium. Analogous results obtain for a special case of pricing to customer firms. Empirical results support differential (premium) pricing for an IT enhanced primary good over an original good.

We construct a renormalization group (RG) transformation for this model and derive exact RG equations which lead to the flow diagram similar to that of the Quantum Hall effect. Renormalization of $θ$ is seen to follow from the loss of information about the initial topological charge in the course of the RG procedure.

description: To address complex problems, scholars are increasingly faced with challenges of integrating diverse knowledge domains. We analyzed the evolution of this convergence paradigm in the broad ecosystem of brain science, which provides a real-time testbed for evaluating two modes of cross-domain integration - subject area exploration via expansive learning and cross-disciplinary collaboration among domain experts. We show that research involving both modes features a 16% citation premium relative to a mono-disciplinary baseline. Further comparison of research integrating neighboring versus distant research domains shows that the cross-disciplinary mode is essential for integrating across relatively large disciplinary distances. Yet we find research utilizing cross-domain subject area exploration alone - a convergence shortcut - to be growing in prevalence at roughly 3% per year, significantly faster than the alternative cross-disciplinary mode, despite being less effective at integrating domains and markedly less impactful. By measuring shifts in the prevalence and impact of different convergence modes in the 5-year intervals before and after 2013, our results indicate that these counterproductive patterns may relate to competitive pressures associated with global Human Brain flagship funding initiatives. Without additional policy guidance, such Grand Challenge flagships may unintentionally incentivize such convergence shortcuts, thereby undercutting the advantages of cross-disciplinary teams in tackling challenges calling on convergence.

Given a finite cell-complex $X$, we study the function $ξ\mapsto \cat(X,ξ)$ where $ξ$ varies in the cohomology space $H^1(X;\R)$. Note that $\cat(X,ξ)$ turns into the classical Lusternik - Schnirelmann category $\cat(X)$ in the case $ξ=0$. Interest in $\cat(X,ξ)$ is based on its applications in dynamics where it enters estimates of complexity of the chain recurrent set of a flow admitting Lyapunov closed 1-forms.

description: Solar nuclear reactions can occasionally produce sub-MeV elusive beyond the Standard Model particles that escape the solar interior without further interactions. This study focuses on massive spin-one particles. We construct the general theoretical framework and identify two crucial mixing sources involving the photon, which facilitate communication between the hidden and visible sectors: kinetic mixing with the photon, and plasma-induced mixing due to thermal electron loops. For both cases, we focus on the second stage of the solar proton-proton chain and evaluate the fluxes of monochromatic 5.49~MeV hidden vectors produced by the $p(d, ^3{\rm He})γ^\prime$ nuclear reaction. We then investigate their terrestrial detection via Compton-like scatterings. The incoming fluxes are polarized, and we evaluate the cross sections for Compton-like scatterings for transverse and longitudinal vectors. Finally, we apply this framework to a concrete case by investigating the sensitivity of the forthcoming Jiangmen Underground Neutrino Observatory (JUNO) experiment and identifying parameter space where current terrestrial bounds will be improved.

Maximal violation of the CGLMP inequality for infinite dimensional states

description: We present a much simplified version of the CGLMP inequality for the 2 x 2 x d Bell scenario. Numerical maximization of the violation of this inequality over all states and measurements suggests that the optimal state is far from maximally entangled, while the best measurements are the same as conjectured best measurements for the maximally entangled state. For very large values of d the inequality seems to reach its minimal value given by the probability constraints. This gives numerical evidence for a tight quantum Bell inequality (or generalized Csirelson inequality) for the 2 x 2 x inf scenario.

description: We examine symmetries of chiral four-dimensional vacua of Type IIB flux compactifications with vanishing superpotential $W=0$. We find that the ${\cal N}=1$ supersymmetric MSSM-like and Pati-Salam vacua possess enhanced discrete symmetries in the effective action below the mass scale of stabilized complex structure moduli and dilaton. Furthermore, a generation number of quarks/leptons is small on these vacua where the flavor, CP and metaplectic modular symmetries are described in the framework of eclectic flavor symmetry.

Does Giving Pupils Leadership Roles Within Extra-Curricular PE Clubs Improve Their Leadership Skills Within Curriculum-Time PE Lessons?
Creators: name: Henry, L
Publisher: name: The School of Education and Communities, University of East London
Year: 2019

description: The purpose of this enquiry is to identify if there is a link between pupils being given the opportunity to develop their leadership skills in extra-curricular clubs and then using them within curriculum-time physical education (PE) lessons. To investigate this question, four pupils were identified as attending extra-curricular clubs regularly and not displaying acts of leadership within PE lessons. An intervention was put in place in which the pupils, with teacher support, organised drills to teach to their peers in the extra-curricular clubs. Pupils were then consulted on their opinions of leadership and re-observed to see if there was any improvement in their leadership ability or confidence to be a leader. The results of this study could have practical implications for PE teachers’ practice within extra-curricular clubs.

description: We present an optical, X-ray, and radio analysis of the starburst in the Abell 1835 cluster's central cD galaxy. The dense gas surrounding the galaxy is radiating X-rays with a luminosity of ~1E45 erg/s consistent with a cooling rate of ~1000-2000 solar masses per year. However, Chandra and XMM-Newton observations find less than 200 solar masses per year of gas cooling below ~2 keV, a level that is consistent with the cD's current star formation rate of 100-180 solar masses per year. One or more heating agents (feedback) must then be replenishing the remaining radiative losses. The heat fluxes from supernova explosions and thermal conduction alone are unable to do so. However, a pair of X-ray cavities from an AGN outburst has deposited ~1.7E60 erg into the surrounding gas over the past 40 Myr. The corresponding jet power 1.4E45 erg/sec is enough to offset most of the radiative losses from the cooling gas. The jet power exceeds the radio synchrotron power by ~4000 times, making this one of the most radiatively inefficient radio sources known. The large jet power implies that the cD's supermassive black hole accreted at a mean rate of ~0.3 solar masses per year over the last 40 Myr or so, which is a small fraction of the Eddington accretion rate for a 10E9 solar mass black hole. The ratio of the bulge growth rate through star formation and the black hole growth rate through accretion is consistent with the slope of the (Magorrian) relationship between bulge and central black hole mass in nearby quiescent galaxies. The consistency between net cooling, heating (feedback), and the cooling sink (star formation) in this system resolves the primary objection to traditional cooling flow models. (abridged)

description: In animals, epithelial tissues are barriers against the external environment, providing protection against biological, chemical, and physical damage. Depending on the animal's physiology and behavior, these tissues encounter different types of mechanical forces and need to provide a suitable adaptive response to ensure success. Therefore, understanding tissue mechanics in different contexts is an important research area. Here, we review recent tissue mechanics discoveries in a few early-divergent non-bilaterian animals -- Trichoplax adhaerens, Hydra vulgaris, and Aurelia aurita. We highlight each animal's simple body plan and biology, and unique, rapid tissue remodeling phenomena that play a crucial role in its physiology. We also discuss the emergent large-scale mechanics that arise from small-scale phenomena. Finally, we emphasize the enormous potential of these non-bilaterian animals to be model systems for further investigation in tissue mechanics.

Issues in Roma Education: The Relationship Between Language and the Educational Needs of Roma Students
Creators: name: Butterworth, A.
Publisher: name: The School of Education and Communities, University of East London
Year: 2019

description: Roma students in the UK are reported as having significantly lower levels of educational attainment than their UK peers (DfE 2014). Existing research has attributed this to the multifaceted barriers Roma students face as an intrinsic part of their educational trajectory in the UK. Language as a barrier to educational engagement for Roma young people and, subsequently, their differentiated educational needs are repeated as key barriers across much of this research. This article seeks to explore the outcomes of the interrelation between these two significant barriers to educational engagement as a prerequisite to exploring strategies to improve educational outcomes for Roma students in the UK.
Giant rectification in segmented, strongly interacting, spin chains despite the presence of perturbations

description: In Phys. Rev. Lett. 120, 200603 (2018), a segmented XXZ spin chain with zero anisotropy in one half and a large anisotropy on the other half gave rise to a spin current rectification which is perfect in the thermodynamic limit. Here we extend the previous study to segmented chains with interacting integrable as well as non-integrable halves, considering even cases in which no ballistic transport can emerge in either half. We demonstrate that, also in this more general case, it is possible to obtain giant rectification when the two interacting half chains are sufficiently different. We also show that the mechanism causing this effect is the emergence of an energy gap in the excitation spectrum of the out-of-equilibrium insulating steady state in one of the two biases. Finally we demonstrate that in the thermodynamic limit there is no perfect rectification when each of the two half chains is interacting.

description: Excerpts from the report: Lower prices, commercial credit, and food aid programs are important tools for assisting U.S. exports of a variety of agricultural commodities. Export programs of the Commodity Credit Corporation that use those tools have helped maintain or expand U.S. market shares in some countries, but they may not be sufficient to offset other factors that may weaken U.S. market position. U.S. farm exports have fallen in recent years. This report describes these programs, examines the effectiveness of some, and examines similar programs of competing nations.

description: On 24 February 2022, Russia invaded Ukraine, starting what is now known as the Russo-Ukrainian War, initiating an online discourse on social media. Twitter as one of the most popular SNs, with an open and democratic character, enables a transparent discussion among its large user base. Unfortunately, this often leads to Twitter's policy violations, propaganda, abusive actions, civil integrity violation, and consequently to user accounts' suspension and deletion. This study focuses on the Twitter suspension mechanism and the analysis of shared content and features of the user accounts that may lead to this. Toward this goal, we have obtained a dataset containing 107.7M tweets, originating from 9.8 million users, using Twitter API. We extract the categories of shared content of the suspended accounts and explain their characteristics, through the extraction of text embeddings in junction with cosine similarity clustering. Our results reveal scam campaigns taking advantage of trending topics regarding the Russia-Ukrainian conflict for Bitcoin and Ethereum fraud, spam, and advertisement campaigns. Additionally, we apply a machine learning methodology including a SHapley Additive explainability model to understand and explain how user accounts get suspended.
