description: Trapped-ion systems are among themost promising hardware candidates for large scale quantum computing and quantumsimulation. In order to scale up such devices, it is necessary to engineer extremehigh vacuum(XHV) environments to prevent background gas from disrupting the ion crystal. Here we present a new cryogenic ion trapping system designed for long time storage of large ion chains. Our apparatus is based on a segmented-blade ion trap enclosed in a 4Kcryostat, which enables us to routinely trap and hold over 100 171Yb+ions for hours in a linear configuration, due to low background gas pressure from differential cryo-pumping.We characterize theXHVcryogenic environmentmeasuring pressures below10-11 Torr by recording both inelastic and elastic collisions between the ion chain and themolecular background gas.Wealso demonstrate coherent one and two-qubit operations and nearly equidistant ion spacing for chains of up to 44 ions using anharmonic axial potentials, in order to enable better detection and single ion addressing in large ion arrays.We anticipate that this reliable production and lifetime enhancement of large linear ion chainswill enable quantum simulation ofmodels that are intractable with classical computermodeling.

description: The epitaxial growth of germanene on semiconducting GaAs(0001) substrate is studied using $ab$-$initio$ calculations. The interaction of the germanene is found to be minimum with the substrate. Our obtained results strongly indicate that it is possible to take off germanene from the substrate to make it free standing. We demonstrate a methods to achieve this aim. We also address the electronic structure of germanene on GaAs(0001) substrate and found to be the Dirac cone shift above the Fermi level with the spltting of 160 meV. Forthermore, we calculate the band structure of the free standing germanene with and without substrate and found band gap of 24 meV due to the intrinsic spin orbit coupling.

description: Purpose: This case study is presented to inform the reader of potential speech, language, cognitive, and emotional characteristics in preadolescent cluttering. Method: This case study describes a 10-year-old boy who started to clutter during preadolescence. The case illustrates that, in some adolescents, cluttering can co-occur with temporary stuttering-like behavior. In this case, signs of disturbances in speech-language production associated with behavioral impulsiveness as a young child were noted. Speech, language, cognitive, and emotional results of the case are reported in detail. Results: The changes in fluency development are reported and discussed within the context of changes in the adolescent brain as well as adolescent cognitive and emotional development. While being unaware of their speech condition before adolescence, during preadolescence, the changes in brain organization lead to an increase in rate and a decrease in speech control. Given that the client had limited understanding of what was occurring, they were at risk of developing negative communication attitudes. Speech-language therapists are strongly advised to monitor children with cluttering signals in the early years of their adolescence. Supplemental Material S1.

description: We study some differential complexes in continuum mechanics that involve both symmetric and non-symmetric second-order tensors. In particular, we show that the tensorial analogue of the standard grad-curl-div complex can simultaneously describe the kinematics and the kinetics of motions of a continuum. The relation between this complex and the de Rham complex allows one to readily derive the necessary and sufficient conditions for the compatibility of the displacement gradient and the existence of stress functions on non-contractible bodies. We also derive the local compatibility equations in terms of the Green deformation tensor for motions of $2$D and $3$D bodies, and shells in curved ambient spaces with constant curvatures.

description: The physics of spin exchange collisions have fueled several discoveries in fundamental physics and numerous applications in medical imaging and nuclear magnetic resonance. We here report on the experimental observation and theoretical justification of spin-noise exchange, the transfer of spin-noise from one atomic species to another. The signature of spin-noise exchange is an increase of the total spin-noise power at low magnetic fields, on the order of 1 mG, where the two-species spin-noise resonances overlap. The underlying physical mechanism is the two-species spin-noise correlation induced by spin-exchange collisions.

description: Optical second harmonic generation is a second-order nonlinear process that combines two photons of a given frequency into a third photon at twice the frequency. Due to the symmetry constraints, it is widely used as a sensitive probe to detect broken inversion symmetry and local polar order. Analytical modeling of the electric-dipole SHG response is essential to extract fundamental properties of materials from experiments. However, complexity builds up dramatically in the analytical model when the probed crystal is of a low bulk crystal symmetry, with a low-symmetry surface orientation, exhibits absorption and dispersion, and consists of multiple interfaces. As a result, there is a largely uneven landscape in the literature on the SHG modeling of new materials, involving numerous approximations and a wide range of (in)accuracies, leading to a rather scattered dataset of reported SHG nonlinear susceptibility. Towards streamlining the reliability and accuracy of this process, we have developed an open-source package called the Second Harmonic Analysis of Anisotropic Rotational Polarimetry (SHAARP) which derives analytical solutions and performs numerical simulations of reflection SHG from a single interface for homogeneous crystals. Five key generalizations in SHG modeling are implemented, including all crystal symmetries down to triclinic, any crystal orientation, complex dielectric tensor (refractive indices) with frequency dispersion, and general polarization states of the light. SHAARP enables accurate anisotropic modeling of SHG response for a broad range of materials systems. The method is extendible to multiple interfaces.

N6-methyladenosine bimodal peak signature mediates acute and selective stress translation by specialized cytoskeletal ribosomes via a MARK4-FTO-PKR axis
Creators: Saleme, Bruno
Publisher: name: University of Alberta Library
Year: 2023

Cellular responses to stress are temporally-organized complex pathways designed to prioritize resources and adapt in order to promote repair and survival. In severe stress, the energetically

demanding mRNA translation is mostly inhibited, but it is not known whether there is a universal mechanism that preserves the translation of acutely needed stress response proteins (SRPs).

Here we show that the dynamic epitranscriptomic n6-methyladenosine (m6A) mRNA modification is used as an SRP mRNA marker, allowing for selective translation in microdomains

consisting of specialized ribosomes (compatible with the recent discovery of ribosomal diversity), the m6A demethylase FTO, and stress related kinases (MARK4 and PKR), attached on the cytoskeleton (i.e. g tubulin). SRP mRNAs are characterized by a dual peak methylation pattern, downstream of their 3UTR segment, which hosts the eIF2a kinase PKR that inhibits their translation when they exit the nucleus. FTO, which also binds at the same site, is activated via a T6 phosphorylation by the stress kinase MARK4 and removes this dual peak methylation signature, removing the inhibitory effects of PKR, allowing the translation of SRPs.

We describe a previously unrecognized, microtubule associated translation system for the translation of SRPs during the critical early stages of acute stress, when the translation of other

proteins is mostly inhibited.
Coherent Time-Domain Canceling of Interference for Radio Astronomy

description: Radio astronomy is vulnerable to interference from a variety of anthropogenic sources. Among the many strategies for mitigation of this interference is coherent time-domain canceling (CTC), which ideally allows one to "look through" interference, as opposed to avoiding the interference or deleting the afflicted data. However, CTC is difficult to implement, not well understood, and at present this strategy is not in regular use at any major radio telescope. This paper presents a review of CTC including a new comprehensive study of the capabilities and limitations of CTC using metrics relevant to radio astronomy, including fraction of interference power removed and increase in noise. This work is motivated by the emergence of a new generation of communications systems which pose a significantly increased threat to radio astronomy and which may overwhelm mitigation methods now in place.

description: Matsumoto, Saito, and Matoba recently proposed the Walsh figure of merit (WAFOM), which is a computable criterion for quasi-Monte Carlo point sets using digital nets. Several algorithms have been proposed for finding low-WAFOM point sets. In the existing algorithms, the number of points is fixed in advance, but extensible point sets are preferred in some applications. In this paper, we propose a random search algorithm for extensible low-WAFOM point sets. For this, we introduce a method that uses lookup tables to compute WAFOM faster. Numerical results show that our extensible low-WAFOM point sets are comparable with Niederreiter--Xing sequences for some low-dimensional and smooth test functions.

Numerical investigation of the superfluid transition in low dimensions and in anisotropic systems
Creators: Nguyen, Phong
Publisher: name: University of Alberta Library
Year: 2023

The main theme of this thesis is the superfluid transition in reduced dimensions and in anisotropic and inhomogeneous systems. Using state-of-the-art computational methodology, we carry out large-scale, numerically exact computer simulations to study this topic, making use of classical and quantum lattice models. In particular, we investigate the behavior of the specific heat in two-dimensional (2D) superfluids, using the classical $x$-$y$ Hamiltonian on the square lattice as a minimal, paradigmatic model. The specific heat is found to exhibit a well-defined peak in the thermodynamic limit, at a temperature above the superfluid transition temperature. We then attempt to explore a possible dimensional crossover in a 2D superfluid in the presence of an externally imposed density modulation, in the context of the $|\psi|^4$ classical field theory. As the strength of the modulation increases, the physics of the system becomes more similar to that of the anisotropic $x-y$ model, characterized by a decreased superfluid transition temperature and an anisotropic response, but with no dimensional crossover. Finally, we examine the phase diagram of lattice hard core bosons with anisotropic nearest-neighbor interactions that can vary between repulsion and attraction in different directions. This phase diagram includes a superfluid phase, as well as two crystalline phases at half-filling, either checkerboard or striped, but no ``supersolid'' phase; which is similar to the case of isotropic interactions. Our predictions appear to be in principle testable experimentally, for example by performing measurements on thin films of superfluid helium or cold atom assemblies.

description: In this comment on "The Markov blanket trick: On the scope of the free energy principle and active inference" by Raja and colleagues (2021) in Physics of Life Reviews, I argue that the argument presented by the authors is valid; however, I claim that the argument contains a flawed premise, which undermines their conclusions. In addition, I argue that work on the FEP that has appeared since the target paper was published underwrites a cogent response to the issues that are raised by Raja and colleagues.

description: Modern Galactic surveys have revealed an ancient merger that dominates the stellar halo of our Galaxy (\textit{Gaia}-Sausage-Enceladus, GSE). Using chemical abundances and kinematics from the H3 Survey, we identify 5559 halo stars from this merger in the radial range $r_{\text{Gal}}=6-60\text{ kpc}$. We forward model the full selection function of H3 to infer the density profile of this accreted component of the stellar halo. We consider a general ellipsoid with principal axes allowed to rotate with respect to the Galactocentric axes, coupled with a multiply-broken power law. The best-fit model is a triaxial ellipsoid (axes ratios 10:8:7) tilted $25^\circ$ above the Galactic plane towards the Sun and a doubly-broken power law with breaking radii at 12 kpc and 28 kpc. This result resolves the long-standing dichotomy in literature values of the halo breaking radius, being at either $\sim15\text{ kpc}$ or $\sim30\text{ kpc}$ assuming a singly-broken power law. N-body simulations suggest that the breaking radii are connected to apocenter pile-ups of stellar orbits, and so the observed double-break provides new insight into the initial conditions and evolution of the GSE merger. Furthermore, the tilt and triaxiality of the stellar halo could imply that a fraction of the underlying dark matter halo is also tilted and triaxial. This has important implications for dynamical mass modeling of the Galaxy as well as direct dark matter detection experiments.

description: We develop an approach to constructing the manifestly Lorentz covariant cubic interaction vertices for the four-dimensional massless higher spin bosonic fields with two-component dotted and undotted spinor indices. Such fields automatically satisfy the traceless conditions what simplify form of the equations determining the irreducible massless representation of the Poincar'e group with given helicity. The cubic vertex is formulated in the framework of the BRST approach to higher spin field theory. Use of the above spin-tensor fields allows to simplify a form of the BRST-charge and hence to find the cubic vertices just in terms of irreducible higher spin fields. We derive an equation for the cubic vertex and find solutions for arbitrary spins $s_1,s_2,s_3$ with the number of derivatives $s_1+s_2+s_3$ in the vertex. As an example, we explicitly construct a vertex corresponding to the interaction of a higher spin field with scalars.

description: Several lattice models display a condensation transition in real space when the density of a suitable order parameter exceeds a critical value. We consider one of such models with two conservation laws, in a one-dimensional open setup where the system is attached to two external reservoirs. Both reservoirs impose subcritical boundary conditions at the chain ends. When such boundary conditions are equal, the system is in equilibrium below the condensation threshold and no condensate can appear. Instead, when the system is kept out of equilibrium, localization may arise in an internal portion of the lattice. We discuss the origin of this phenomenon, the relevance of the number of conservation laws, and the effect of the pinning of the condensate on the dynamics of the out-of-equilibrium state.

Naturally, this theory includes all physically viable multi-scalar field theories in flat space-time, in the sense that they don't suffer from Ostrogradski instability \cite{ostro}.

A study of the experiences and perceptions of parents of Black and Minority Ethnic pupils statemented with autism in relation to the educational support provided for their children and for themselves.

description: This study investigates the experiences and perceptions of parents of Black and Minority Ethnic (BME) pupils statemented with autism of the support they receive for their child in education and for themselves.These perceptions are explored alongside the views of stakeholders in education who work to support these pupils and parents. The study expandsupon the work of Perepa (2008) who investigated the cultural influences on the understanding of appropriate social behaviour by BME parents of children within the autism spectrum in a London borough. Since then there has been minimal research on BME parents’ experiences of having a child with autism in education, so this study addresses a gap in research. A qualitative case study approach was adopted using in-depth interviews with participants from one selected local authority in Wales. An interpretivist approach was used to gain an understanding of the researched phenomena within a cultural context. The data was managed for thematic analysis using the qualitative analysis software tool, NVivo. The findings reveal that BME parents receive support from the providers within education rather than from their own ethnic communities. They show a preference for mainstream education, although evidence here suggests that there are fewer specialist resources in these schools compared to special schools. The findings also reveal that their culture, religion, education and socio-economic backgrounds influence BME parents’ ability to access and utilise educational support services. They feel that their ethnicity and cultural needs are not always taken into account inthe‘culturally-blind’ system which appears to be implemented within education, and their expectation is that society should provide them with more support. It is anticipated that these findings would be taken into account by policy makers and contribute to further research in Wales.

description: We study the scaling scenery and limit geometry of invariant measures for the non-conformal toral endomorphism $(x,y) \mapsto (mx \mod 1,ny \mod 1)$ that are Bernoulli measures for the natural Markov partition. We show that the statistics of the scaling can be described by an ergodic CP-chain in the sense of Furstenberg. Invoking the machinery of CP-chains yields a projection theorem for Bernoulli measures, which generalises in part earlier results by Hochman-Shmerkin and Ferguson-Jordan-Shmerkin. We also give an ergodic theoretic criterion for the dimension part of Falconer's distance set conjecture for general sets with positive length using CP-chains and hence verify it for various classes of fractals such as self-affine carpets of Bedford-McMullen, Lalley-Gatzouras and Barański class and all planar self-similar sets.

Post-Newtonian effects on some characteristic timescales of transiting exoplanets

description: Some measurable characteristic timescales $\left\{t_\mathrm{trn}\right\}$ of transiting exoplanets are investigated in order to check preliminarily if their cumulative shifts over the years induced by the post-Newtonian (pN) gravitoelectric (Schwarzschild) and gravitomagnetic (Lense-Thirring) components of the stellar gravitational field are, at least in principle, measurable. Both the primary (planet in front of the star) and the secondary (planet behind the star) transits are considered along with their associated characteristic time intervals: the total transit duration $t_D$, the ingress/egress transit duration $τ$, the full width at half maximum primary transit duration $t_H$, and also the time of conjunction $t_\mathrm{cj}$. For each of them, the net changes per orbit $\langleΔt_D\rangle,\,\langleΔτ\rangle,\,\langleΔt_H\rangle,\,\langleΔt_\mathrm{cj}\rangle$ induced by the aforementioned pN accelerations are analytically obtained; also the Newtonian effect of the star's quadrupole mass moment $J_2^\star$ is worked out. They are calculated for a fictitious Sun-Jupiter system in an edge-on elliptical orbit, and the results are compared with the present-day experimental accuracies for the HD 286123 b exoplanet. Its pN gravitoelectric shift $\left\langleΔt_\mathrm{cj}^\mathrm{1pN}\right\rangle$ may become measurable, at least in principle, at a $\simeq 8\times 10^{-5}$ level of (formal) relative accuracy after about 30 years of continuous monitoring corresponding to about 1000 transits. Systematics like, e.g., confusing time standards, neglecting star spots, neglecting clouds, would likely deteriorate the actual accuracy. The method presented is general enough to be applied also to modified models of gravity.

description: We study a new class of time inhomogeneous Pólya-type urn schemes and give optimal rates of convergence for the distribution of the properly scaled number of balls of a given color to nearly the full class of generalized gamma distributions with integer parameters, a class which includes the Rayleigh, half-normal and gamma distributions. Our main tool is Stein's method combined with characterizing the generalized gamma limiting distributions as fixed points of distributional transformations related to the equilibrium distributional transformation from renewal theory. We identify special cases of these urn models in recursive constructions of random walk paths and trees, yielding rates of convergence for local time and height statistics of simple random walk paths, as well as for the size of random subtrees of uniformly random binary and plane trees.

Body posture predicting methods have many applications, including product design, ergonomic workplace design, human body simulation, virtual reality and animation industry. Initiated in robotics, Inverse Kinematic (IK) method has been widely applied to proactive human body posture estimation. The Analytic Inverse Kinematic (AIK) method is a convenient and time-saving type of IK methods. It is also indicated that, based on AIK methods, a specific body posture can be determined by the optimization of an arbitrary objective function.

The objective of this thesis is to predict the postures of human arms during reaching tasks. In this research, a human body model is established in MATLAB, where the Middle Rotation Axis (MRA) analytic kinematic method is accomplished, based on this model. The joint displacement function and joint discomfort function are selected to be initially applied in this improved AIK method. Then a bi-criterion objective function is proposed by integrating the joint displacement function and joint discomfort function, with the suboptimal value of the coefficient, in the integrated objective function, determined by golden section search.

Results show that neither the joint displacement function nor the joint discomfort function predicts postures that are close enough to natural upper limb postures of human being, during reaching tasks. The accuracy of the arm postures, predicted by the proposed objective function, is the most satisfactory.

description: Primordial black holes (PBHs) can be produced in the very early Universe due to the large density fluctuations. The cosmic background of axion-like particles (ALPs) could be non-thermally generated by PBHs. In this paper, we investigate the ALPs emitted by ultra-light PBHs with the mass range $10 \, {\rm g} \lesssim M_{\rm PBH} \lesssim 10^9 \, \rm g$, in which PBHs would have completely evaporated before the start of Big Bang Nucleosynthesis (BBN) and can therefore not be directly constrained. In this case, the minimal scenario that ALPs could interact only with photons is supposed. We study the stochastic oscillations between the ALPs and photons in the cosmic magnetic field in detail. The primordial magnetic field (PMF) can be modelled as the stochastic background field model with the completely non-homogeneous component of the cosmic plasma. Using the latest stringent limits on PMF, we show the numerical results of ALP-photon oscillation probability distributions with the homogeneous and stochastic magnetic field scenarios. The PBH-induced stochastic ALP-photon oscillations in the PMF may have the effects on some further phenomena, such as the cosmic microwave background (CMB), the cosmic X-ray background (CXB), and the extragalactic gamma-ray background (EGB).

description: We find a further class of exact solutions to the Lighthill Whitham Richards Payne (LWRP) traffic flow equations. As before, using two consecutive Lagrangian transformations, a linearization is achieved. Next, depending on the initial density, we either obtain exact formulae for the dependence of the car density and velocity on x, t, or else, failing that, the same result in a parametric representation. The calculation always involves two possible factorizations of a consistency condition. Both must be considered. In physical terms, the lineup usually separates into two offshoots at different velocities. Each velocity soon becomes uniform. This outcome in many ways resembles not only Rowlands, Infeld and Skorupski J. Phys. A: Math. Theor. 46 (2013) 365202 (part I) but also the two soliton solution to the Korteweg-de Vries equation. This paper can be read independently of part I. This explains unavoidable repetitions. Possible uses of both papers in checking numerical codes are indicated at the end. Since LWRP, numerous more elaborate models, including multiple lanes, traffic jams, tollgates etc. abound in the literature. However, we present an exact solution. These are few and far between, other then found by inverse scattering. The literature for various models, including ours, is given. The methods used here and in part I may be useful in solving other problems, such as shallow water flow.

description: Consider a $N\times n$ matrix $Σ_n=\frac{1}{\sqrt{n}}R_n^{1/2}X_n$, where $R_n$ is a nonnegative definite Hermitian matrix and $X_n$ is a random matrix with i.i.d. real or complex standardized entries. The fluctuations of the linear statistics of the eigenvalues \[\operatorname {Trace}f \bigl(Σ_nΣ_n^*\bigr)=\sum_{i=1}^Nf(λ_i),\qquad (λ_i)\ eigenvalues\ of\ Σ_nΣ_n^*,\] are shown to be Gaussian, in the regime where both dimensions of matrix $Σ_n$ go to infinity at the same pace and in the case where $f$ is of class $C^3$, that is, has three continuous derivatives. The main improvements with respect to Bai and Silverstein's CLT [Ann. Probab. 32 (2004) 553-605] are twofold: First, we consider general entries with finite fourth moment, but whose fourth cumulant is nonnull, that is, whose fourth moment may differ from the moment of a (real or complex) Gaussian random variable. As a consequence, extra terms proportional to $ \vert \mathcal{V}\vert ^2=\bigl|\mathbb{E}\bigl(X_{11}^n\bigr) ^2\bigr|^2$ and $κ=\mathbb{E}\bigl \vert X_{11}^n\bigr \vert ^4-\vert {\mathcal{V}}\vert ^2-2$ appear in the limiting variance and in the limiting bias, which not only depend on the spectrum of matrix $R_n$ but also on its eigenvectors. Second, we relax the analyticity assumption over $f$ by representing the linear statistics with the help of Helffer-Sjöstrand's formula. The CLT is expressed in terms of vanishing Lévy-Prohorov distance between the linear statistics' distribution and a Gaussian probability distribution, the mean and the variance of which depend upon $N$ and $n$ and may not converge.

description: A covariant hyper-nuclear energy density functional (EDF) is derived from in medium nucleon meson vertex functionals, assuring the proper description of nuclear mean-field dynamics. The fundamental SU(3) coupling constants for the mean-field relevant vector (m=V) and scalar (m=S) interactions as functionals of the total baryon density are determined. Scalar and vector potentials and the resulting hyperon mean-fields in asymmetric nuclear matter are constructed and discussed, addressing also effects from three-body interactions. Λ- Σ^0 mixing in asymmetric nuclear through the coupling to the background isovector mean-field is addressed.

description: We define a new morphology metric called "patchiness" ($P$) that is sensitive to deviations from the average of a resolved distribution, does not require the galaxy center to be defined, and can be used on the spatially-resolved distribution of any galaxy property. While the patchiness metric has a broad range of applications, we demonstrate its utility by investigating the distribution of dust in the interstellar medium of 310 star-forming galaxies at spectroscopic redshifts $1.36

“Days in the Dirt”: An ethnography on cricket and self
Creators: name: Bowles, Harry
Publisher: name: Cardiff Metropolitan University

Subjects: Sport and exercise psychology

description: This study provides a representation of the lived transitional experiences of a group of student-cricketers on a passage toward professional cricket. Set in the local context of a university cricket academy, the investigation focused on players’ adoption of a cricketing role that they used in combination with their structured cricketing environment to explore what it might be like to be professional cricketers. The aim of the research, therefore, was to portray a culturally embedded process of identity-exploration through which a group of young men arrived at a conception of themselves as ‘cricketers’.The data on which the study is based have been drawn from research conducted over twenty seven monthsfrom November 2010 to March 2013where I, as a researcher, became immersed in the research context as an active member of the participantgroup. The methodological approach of ethnography was used to obtain an insider’saccount of the student-cricket experience as seen from the point of view of the actors involved. Application of traditional ethnographic techniques such as participant observation, note taking and unstructured, field-based ‘interviews’ provided the means through which situated, day-to-day experiences were captured and explored. What is presented, therefore, reflects some of the contextual responses to real-life situations experienced by the group and its individuals, mediated through a developing analytical interest in players’ identity engagements with their cricketing environment from the theoretical standpoint of ‘emerging adulthood’ (Arnett, 2000, 2004). Adding to the ethnographic accounts offered within this thesis, the study contributes a conceptual framework that plots players’ transitional pathways through the academy to share the key points of interaction that impinged on individual participants ‘finding their level’ in the game. Through contact and exposure to a cricketing way of life, players’ involvement with the academy saw their cricketing experiences intensify and their attachments to the game transform. This resulted in individuals either accepting or rejecting cricket based on what they came to know about themselves and the game, with the findings of the research helping to iiifurther understanding on how a group of ‘emerging adults’ engaged with the ‘project’ of their self-identities to reach a point of self-understanding on which to base prospective identity-decisions.
