description: The Krzyż conjecture concerns the largest values of the Taylor coefficients of a non-vanishing analytic function bounded by one in modulus in the unit disk. It has been open since 1968 even though information on the structure of extremal functions is available. The purpose of this paper is to collect various conditions that the coefficients of an extremal function (and various other quantities associated with it) should satisfy if the conjecture is true and to show that each one of these properties is equivalent to the conjecture itself. This may provide several possible starting points for future attempts at solving the problem.
description: Condition (d) in the main Theorem of version 1 of this paper was erroneous. This has been corrected in the subsequent versions v2 and v3. Also, a proof of one implication in the Main Theorem has now been made shorter with respect to v2

Dark energy imprints on the kinematic Sunyaev-Zel'dovich signal

description: We investigate the imprint of dark energy on the kinetic Sunyaev-Zel'dovich (kSZ) angular power spectrum on scales of $\ell=1000$ to $10000$, and find that the kSZ signal is sensitive to the dark energy parameter. For example, varying the constant $w$ by 20\% around $w=-1$ results in a $\gtrsim10\%$ change on the kSZ spectrum; changing the dark energy dynamics parametrized by $w_a$ by $\pm0.5$, a 30\% change on the kSZ spectrum is expected. We discuss the observational aspects and develop a fitting formula for the kSZ power spectrum. Finally, we discuss how the precise modeling of the post-reionization signal would help the constraints on patchy reionization signal, which is crucial for measuring the duration of reionization.

Meta-Weaves: Sector-way non-reciprocal meta surfaces

description: Confluent with the single dimension of time, breach of time-reversal symmetry is usually perceived as a one-dimensional concept. In its ultimate realization--the one-way guiding device--it allows optical propagation in one direction, say $+z$, and forbids it in the opposite direction, $-z$. Hence, in studies of time-reversal asymmetry the mapping $t\mapsto -t$ is naturally associated with $z\mapsto -z$. However, strongly non-reciprocal or one-way nano-scale threads can be used \emph{to weave meta-surfaces} thus adding dimensions to this concept. In this new family of surfaces the aforementioned association \emph{cannot be made}. An example of appropriate threads are the planar one-way particle chains based on the two-type rotation principle. The resulting surfaces--the meta-weaves--posses generalized non-reciprocity such as "sector-way" propagation, and offer new possibilities for controlling light in thin surfaces. We study several meta-weave designs and their asymmetries in the wave-vector space.
Stringent Restriction from the Growth of Large-Scale Structure on Apparent Acceleration in Inhomogeneous Cosmological Models

description: Probes of cosmic expansion constitute the main basis for arguments to support or refute a possible apparent acceleration due to different expansion rates in the universe as described by inhomogeneous cosmological models. We present in this Letter a separate argument based on results from an analysis of the growth rate of large-scale structure in the universe as modeled by the inhomogeneous cosmological models of Szekeres. We use the models with no assumptions of spherical or axial symmetries. We find that while the Szekeres models can fit very well the observed expansion history without a $Λ$, they fail to produce the observed late-time suppression in the growth unless $Λ$ is added to the dynamics. A simultaneous fit to the supernova and growth factor data shows that the cold dark matter model with a cosmological constant ($Λ$CDM) provides consistency with the data at a confidence level of 99.65% while the Szekeres model without $Λ$ achieves only a 60.46% level. When the data sets are considered separately, the Szekeres with no $Λ$ fits the supernova data as well as the $Λ$CDM does, but provides a very poor fit to the growth data with only 31.31% consistency level compared to 99.99% for the $Λ$CDM. This absence of late-time growth suppression in inhomogeneous models without a $Λ$ is consolidated by a physical explanation.

description: Zaslavsky proved in 2012 that, up to switching isomorphism, there are six different signed Petersen graphs and that they could be told apart by their chromatic polynomials, by showing that the latter give distinct results when evaluated at 3. He conjectured that the six different signed Petersen graphs also have distinct zero-free chromatic polynomials, and that both types of chromatic polynomials have distinct evaluations at \emph{any} positive integer. We developed and executed a computer program (running in {\tt SAGE}) that efficiently determines the number of proper $k$-colorings for a given signed graph; our computations for the signed Petersen graphs confirm Zaslavsky's conjecture. We also computed the chromatic polynomials of all signed complete graphs with up to five vertices.

description: A recent analysis of the 4-point correlation function of the passive scalar advected by a time-decorrelated random flow is extended to the N-point case. It is shown that all stationary-state inertial-range correlations are dominated by homogeneous zero modes of singular operators describing their evolution. We compute analytically the zero modes governing the N-point structure functions and the anomalous dimensions corresponding to them to the linear order in the scaling exponent of the 2-point function of the advecting velocity field. The implications of these calculations for the dissipation correlations are discussed.

Some speculations are included on the nature of systems whose large time behavior is described by the new statistics.

description: This scoping review sought to identify and characterize measurement of self-regulation in preschool and elementary aged children. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Review (ScR) guidelines were applied. Databases from the fields of allied health, education, medicine, and social sciences were searched including: CINAHL, Education Database (ProQuest), Education Research Complete, EMBASE, ERIC, iNFORMIT Combined, Medline, PsychINFO, Social Sciences (ProQuest), Teacher Reference Center, and Web of Science. Articles published between 2015 and 2020 were included. Dual review was utilized at all stages and a third reviewer resolved any conflicts. Sixty-seven studies were included in this review. A range of observational, self-report, teacher report, caregiver report, and observational measures of self-regulation were identified. Included studies were primarily published in education and psychology disciplines, with no studies by occupational therapists identified. Although a range of measures were identified in this scoping review, the results highlight the lack of consensus regarding self-regulation measurement that occupational therapists use to design and implement therapy programs to address child emotional and behavioral needs.
Fault-Tolerant Measurement-Based Quantum Computing with Continuous-Variable Cluster States

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A long-standing open question about Gaussian continuous-variable cluster states is whether they enable fault-tolerant measurement-based quantum computation. The answer is yes. Initial squeezing in the cluster above a threshold value of 20.5 dB ensures that errors from finite squeezing acting on encoded qubits are below the fault-tolerance threshold of known qubit-based error-correcting codes. By concatenating with one of these codes and using ancilla-based error correction, fault-tolerant measurement-based quantum computation of theoretically indefinite length is possible with finitely squeezed cluster states.

We also point out that the velocity statistics become gaussian in the approximation consisting in neglecting odd order correlations in front even order ones.

description: Low-energy strong interactions are a major source of background at hadron colliders, and methods of subtracting the associated energy flow are well established in the field. Traditional approaches treat the contamination as diffuse, and estimate background energy levels either by averaging over large data sets or by restricting to given kinematic regions inside individual collision events. On the other hand, more recent techniques take into account the discrete nature of background, most notably by exploiting the presence of substructure inside hard jets, i.e. inside collections of particles originating from scattered hard quarks and gluons. However, none of the existing methods subtract background at the level of individual particles inside events. We illustrate the use of an algorithm that can enable particle-by-particle background discrimination at the Large Hadron Collider, and we envisage this as the basis for a novel event filtering procedure upstream of the official jet reconstruction pipelines. Our hope is that this new technique will improve physics analysis when used in combination with state-of-the-art algorithms in high-luminosity hadron collider environments.

Intramembrane Cavitation as a Predictive Bio-Piezoelectric Mechanism for Ultrasonic Brain Stimulation

description: Low-intensity ultrasonic waves can remotely and nondestructively excite central nervous system (CNS) neurons. While diverse applications for this effect are already emerging, the biophysical transduction mechanism underlying this excitation remains unclear. Recently, we suggested that ultrasound-induced intramembrane cavitation within the bilayer membrane could underlie the biomechanics of a range of observed acoustic bioeffects. In this paper, we show that, in CNS neurons, ultrasound-induced cavitation of these nanometric bilayer sonophores can induce a complex mechanoelectrical interplay leading to excitation, primarily through the effect of currents induced by membrane capacitance changes. Our model explains the basic features of CNS acoustostimulation and predicts how the experimentally observed efficacy of mouse motor cortical ultrasonic stimulation depends on stimulation parameters. These results support the hypothesis that neuronal intramembrane piezoelectricity underlies ultrasound-induced neurostimulation, and suggest that other interactions between the nervous system and pressure waves or perturbations could be explained by this new mode of biological piezoelectric transduction.

description: Apparent mass measurements at the bottom of granular packings inside a vertical tube in relative motion are reported. They demonstrate that Janssen's model is valid over a broad range of velocities v. The variability of the measurements is lower than for static packings and the theoretical exponential increase of the apparent mass with the height of the packing is precisely followed (the corresponding characteristic screening length is of the order of the tube diameter). The limiting apparent mass at large heights is independent of v and significantly lower than the static value.

description: We introduce a new oriented evolving graph model inspired by biological networks. A node is added at each time step and is connected to the rest of the graph by random oriented edges emerging from older nodes. This leads to a statistical asymmetry between incoming and outgoing edges. We show that the model exhibits a percolation transition and discuss its universality. Below the threshold, the distribution of component sizes decreases algebraically with a continuously varying exponent depending on the average connectivity. We prove that the transition is of infinite order by deriving the exact asymptotic formula for the size of the giant component close to the threshold. We also present a thorough analysis of aging properties. We compute local-in-time profiles for the components of finite size and for the giant component, showing in particular that the giant component is always dense among the oldest nodes but invades only an exponentially small fraction of the young nodes close to the threshold.

description: The anomalous scaling in the Kraichnan model of advection of the passive scalar by a random velocity field with non-smooth spatial behavior is traced down to the presence of slow resonance-type collective modes of the stochastic evolution of fluid trajectories. We show that the slow modes are organized into infinite multiplets of descendants of the primary conserved modes. Their presence is linked to the non-deterministic behavior of the Lagrangian trajectories at high Reynolds numbers caused by the sensitive dependence on initial conditions within the viscous range where the velocity fields are more regular. Revisiting the Kraichnan model with smooth velocities we describe the explicit solution for the stationary state of the scalar. The properties of the probability distribution function of the smeared scalar in this state are related to a quantum mechanical problem involving the Calogero-Sutherland Hamiltonian with a potential.

description: Dissipation-driven quantum state engineering uses the environment to steer the state of quantum systems and preserve quantum coherence in the steady state. We show that modulating the damping rate of a microwave resonator generates a vacuum squeezed state of arbitrary squeezing strength, thereby constituting a mechanism allowing perfect squeezing. Given the recent experimental realizations in circuit QED of a microwave resonator with a tunable damping rate [Yin et al., Phys. Rev. Lett. 110, 107001 (2013)], superconducting circuits are an ideal playground to implement this technique. By dispersively coupling a qubit to the microwave resonator, it is possible to obtain qubit-state dependent squeezing.

description: We show that the optical responses below the Mott gap can be used to probe the spin-triplet excitations in valence bond solid (VBS) phases in Mott insulators. The optical conductivity in this regime arises due to the electronic polarization mechanism via virtual electron hopping processes. We apply this mechanism to the Hubbard model with spin-orbit couplings and/or the corresponding spin model with significant Dzyaloshinskii-Moriya (DM) interactions, and compute the optical conductivity of VBS states on both ideal and deformed Kagome lattices. In case of the deformed Kagome lattice, we study the antiferromagnet, Rb$_2$Cu$_3$SnF$_{12}$ with the pinwheel VBS state. In case of the ideal Kagome lattice, we explore the optical conductivity signatures of the spin-triplet excitations for three VBS states with (1) a 12-site unit cell, (2) a 36-site unit cell with six-fold rotation symmetry, and (3) a 36-site unit cell with three-fold rotation symmetry, respectively. We find that increasing the DM interactions generally leads to broad and smooth features in the optical conductivity with interesting experimental consequences. The optical conductivity reflects the features of the spin-triplet excitations that can be measured in future experiments.

description: A statistical mechanics argument relating partition functions to martingales is used to get a condition under which random geometric processes can describe interfaces in 2d statistical mechanics at criticality. Requiring multiple SLEs to satisfy this condition leads to some natural processes, which we study in this note. We give examples of such multiple SLEs and discuss how a choice of conformal block is related to geometric configuration of the interfaces and what is the physical meaning of mixed conformal blocks. We illustrate the general ideas on concrete computations, with applications to percolation and the Ising model.

description: Poster for Cool Stars 21 Stellar helium abundances strongly determine their structure and evolution. However, since helium cannot be detected directly in the photospheres of cool stars, helium abundances are one of the most poorly-constrained inputs to stellar models. It is therefore typical to assume a relationship with the initial abundances of other heavy elements, typically of linear form described by a gradient ΔY/ΔZ. Attempts to determine from globular-cluster stellar populations and Galactic H-II regions have so far not yielded any consensus about empirically reasonable values of ΔY/ΔZ, or, for that matter, even whether such a linear relation is observationally justifiable. Separately, asteroseismology permits the inference of stellar helium abundances, either directly through acoustic-glitch measurements, or indirectly through the forward modelling of stellar oscillation mode frequencies. Using constraints on the initial helium abundance derived from ensemble asteroseismology and stellar forward modelling against individual mode frequencies of a collection of field stars in the TESS, Kepler, and K2 fields, we characterise the helium-metallicity relation of the brightest cool stars in the solar neighbourhood. We find a large spread of seismic initial helium abundances for any given metallicity, rather than a single well-defined linear enrichment law.

description: We offer a new example of conformal invariance far from equilibrium -- the inverse cascade of Surface Quasi-Geostrophic (SQG) turbulence. We show that temperature isolines are statistically equivalent to curves that can be mapped into a one-dimensional Brownian walk (called Schramm-Loewner Evolution or SLE$_κ$). The diffusivity is close to $κ=4$, that is iso-temperature curves belong to the same universality class as domain walls in the O(2) spin model. Several statistics of temperature clusters and isolines are measured and shown to be consistent with the theoretical expectations for such a spin system at criticality. We also show that the direct cascade in two-dimensional Navier-Stokes turbulence is not conformal invariant. The emerging picture is that conformal invariance may be expected for inverse turbulent cascades of strongly interacting systems.

description: Susana Romano Sued’s Procedimiento. Memoria de la Perla y la Ribera is an intense hybrid text in which the forms of testimony, conveyed by the poetic prose, have erected a double construction. One side of this construction is a tomb of the missing, those disappeared in the clandestine detention centers (CDC); the other side is a monument to the will to survive. The writing presents ghostly voices and bodies and at the same time inserts them in their everyday desperate suffering, without any concessions and often with sharp irony. The narration is built upon bodily sensation, and jailers are all the more sadistic since they confront Jewish women. All of the ideological ingredients of radical evil are articulated via actions, and only writing, as a space of conscience and memory, escapes this evil and supports the will to survive. Language becomes a transgressor; the fragmentation of the world is reflected in the fragmentation of discourse and in the multiple voices that create it. In this degraded scene, the word insists on “poetically capturing the testimony and transforming the memory in a factor of clarification of the subjectivity and of transmission of the experience.” These peculiar forms of speech, this complex staging of a multiple and open textuality are the subjects of this study.

description: In this article we investigate aspects of entanglement entropy and mutual information in a large-N strongly coupled noncommutative gauge theory, both at zero and at finite temperature. Using the gauge-gravity duality and the Ryu-Takayanagi (RT) prescription, we adopt a scheme for defining spatial regions on such noncommutative geometries and subsequently compute the corresponding entanglement entropy. We observe that for regions which do not lie entirely in the noncommutative plane, the RT-prescription yields sensible results. In order to make sense of the divergence structure of the corresponding entanglement entropy, it is essential to introduce an additional cut-off in the theory. For regions which lie entirely in the noncommutative plane, the corresponding minimal area surfaces can only be defined at this cut-off and they have distinctly peculiar properties.

Excited random walk with periodic cookies

description: In this paper we consider an excited random walk on $\mathbb{Z}$ in identically piled periodic environment. This is a discrete time process on $\mathbb{Z}$ defined by parameters $(p_1,\dots p_M) \in [0,1]^M$ for some positive integer $M$, where the walker upon the $i$-th visit to $z \in \mathbb{Z}$ moves to $z+1$ with probability $p_{i\pmod M}$, and moves to $z-1$ with probability $1-p_{i \pmod M}$. We give an explicit formula in terms of the parameters $(p_1,\dots,p_M)$ which determines whether the walk is recurrent, transient to the left, or transient to the right. In particular, in the case that $\frac{1}{M}\sum_{i=1}^{M}p_{i}=\frac {1}{2}$ all behaviors are possible, and may depend on the order of the $p_i$. Our framework allows us to reprove some known results on ERW with no additional effort.

description: We consider the universal solution of the Gervais-Neveu-Felder equation in the ${\cal U}_q(sl_2)$ case. We show that it has a quasi-Hopf algebra interpretation. We also recall its relation to quantum 3-j and 6-j symbols. Finally, we use this solution to build a q-deformation of the trigonometric Lamé equation.

Internal Communication and Employee Engagement: A Work-Based Study of the Lived Experiences of Queensland Police Service Employees
Creators: name: Martin, Rebecca
Publisher: name: University of Southern Queensland
Year: 2023
Subjects: Internal Communication, Employee engagement

description: The Queensland Police Service (QPS) is the primary law enforcement agency for Queensland responsible for providing policing services to the community. As in many other jurisdictions, the QPS faces increased and changing service delivery demands. Simply maintaining a ‘traditional’ policing model is no longer sustainable and given anticipated demographic, and economic changes it is imperative the QPS maintains an engaged workforce. The annual Working for Queensland (WFQ) survey highlights that QPS agency engagement levels have remained relatively constant at 50-57 percent since the survey commenced in 2013, despite concerted attention by senior leaders to improve engagement levels. The term ’employee engagement’ is a contested concept there is a lack of consensus on an accepted definition for it. This research defines employee engagement as “employees’ positive attitude towards their organisation in terms of motivation and inspiration that releases discretionary effort to achieve organisational goals”. This meaning incorporates key aspects of the definition which applies to ‘agency engagement’ in the WFQ survey. This work-based study explores how QPS employees of different ranks and levels perceive and explain WFQ results related to internal communication and employee engagement to identify opportunities for senior leaders to improve engagement levels. The study adopts a two-phase qualitative method, blending quantitative analysis of WFQ data, with contextualisation of qualitative data obtained in personal interviews. The study focuses on employee perspectives relying as much as possible on lived experiences to understand the WFQ results to identify interventions to improve engagement. By applying thematic analysis, the qualitative data collected are analysed in a manner which respects and represents the subjectivity of participants opinions and experiences, while also acknowledging and embracing the reflexive influence of the researcher interpretations. The results demonstrate a willingness of QPS employees to participate in research to have their ‘voice’ heard. Findings support further training for managers and leaders to develop social competencies to improve internal communication and feedback to employees.
Continuity properties of the lower spectral radius

description: The lower spectral radius, or joint spectral subradius, of a set of real $d \times d$ matrices is defined to be the smallest possible exponential growth rate of long products of matrices drawn from that set. The lower spectral radius arises naturally in connection with a number of topics including combinatorics on words, the stability of linear inclusions in control theory, and the study of random Cantor sets. In this article we apply some ideas originating in the study of dominated splittings of linear cocycles over a dynamical system to characterise the points of continuity of the lower spectral radius on the set of all compact sets of invertible $d \times d$ matrices. As an application we exhibit open sets of pairs of $2 \times 2$ matrices within which the analogue of the Lagarias-Wang finiteness property for the lower spectral radius fails on a residual set, and discuss some implications of this result for the computation of the lower spectral radius.

Perinatal outcomes of Pasifika women in Australia: A work-based integrative literature review and discussion

Subjects: Perinatal, Pasifika, Maternity, Neonate, Transcultural

description: Perinatal experience has tremendous impact upon women, families and communities during a key point in time and lays the foundation for a healthy experience of motherhood. Perinatal outcomes for Pasifika women and neonates differ from those of their non-Pasifika counterparts. This is an understudied area in Australia despite the growth of this population group in recent years. This paucity of information was hampering the development of a targeted Pasifika midwifery clinic in the West Moreton Hospital and Health Service. A work-based project was undertaken to assess the best way in which to address the problem and to develop the necessary skills to do so. This process led to the development of a research project, an integrative literature review. This review, investigating perinatal outcomes for Pasifika women in Australia and highlighting gaps in the existing evidence, was then carried out. This thesis presents a discussion on the process of undertaking the work based project, the review of the literature and the outcomes of the process. Work-based projects and learning are discussed including the Master of Professional Studies program offered at UniSQ. The triple dividend of this project; student learning; organisational gain; and wider community gain are presented and evaluated along with recommendations for further research and future education.
