description: We present some wormhole configurations using analytic and numerical solutions of the Euclidean field equations considering Einstein Gauss Bonnet dilaton coupled interaction in the Robertson Walker metric. Analytic solutions invoking slow-roll type approximation for some potentials yield identical wormholes in the early era. Eventually, in a later era, the universe enters to an expanding era much faster than usual inflation accompanied by oscillations with analytic continuation τ=it. The numerical solutions of wormholes in terms of the scale factor a(τ) are almost identical for some standard potentials of the dilaton field, except for the evolution of potentials. The Hubble parameter and deceleration parameter obtained by curve fit of a(τ) of the numerical solution of wormhole yield an inflationary era away from the throat of the wormhole using τ=it. A sharp decay of the potential is also observed.

description: We present a method of near-infrared image reconstruction based on spatial modulation instability in a photorefractive strontium barium niobate crystal. The conditions that lead to the formation of modulation instability at near-infrared are discussed depending on the theory of modulation instability gain. Experimental results of scattered image reconstruction at the 1064 nm wavelength show the maximum cross-correlation coefficient and cross-correlation gain are 0.57 and 2.09 respectively. This method is expected to be an aid for near-infrared imaging technologies.

description: Criminal behavior and the assessment of legal insanity have always been topics of primary concern for the justice system and, at the same time, of great interest to mental health experts. Neuroscience has given mental health specialists an incredible tool to investigate the brain, but the use of neuroimaging techniques in criminal trials has been received with a significant degree of resistance. This thesis illustrates an overview of the techniques involved in the study of the brain that gave birth to modern neuroscience. Moreover, it highlights the philosophical consequences of some neuroscientific experiments that have alerted legal scholars to the problems of free will and criminal responsibility. This contribution goes in-depth in analyzing the normative components of criminal responsibility according to Italian law, and it presents some comparisons with Anglo-American law. Additionally, the present work focuses on the judgment of criminal responsibility in insanity defense cases and the controversies around the mental conditions that can be relevant for a not guilty by reason of insanity verdict. Some real forensic cases are illustrated and discussed. They concern the role of neuroscientific evidence and a debate on the relevance of a personality disorder for the insanity defense. This thesis addresses the problems of translation of legal terms into scientific concepts and, the other way around, of scientific findings into pieces of evidence that are meaningful for legal doctrine. In conclusion, the thesis aims to give an overall outlook on the relationship between law and contemporary forensic neuroscience.

description: We study the phase diagram of the $(1+1)$-dimensional Gross-Neveu model with both $g_x^2(\barψψ)^2$ and $g_y^2(\barψiγ_5ψ)^2$ interaction terms on a spatial lattice. The continuous chiral symmetry, which is present in the continuum model when $g_x^2=g_y^2$, has a mixed 't~Hooft anomaly with the charge conservation symmetry, which guarantees the existence of a massless mode. However, the same 't~Hooft anomaly also implies that the continuous chiral symmetry is broken explicitly in our lattice model. Nevertheless, from numerical matrix product state simulations we find that, for certain parameters of the lattice model, the continuous chiral symmetry reemerges in the infrared fixed point theory, even at strong coupling. We argue that, to understand this phenomenon, it is crucial to go beyond mean-field theory (or, equivalently, beyond the leading order term in a $1/N$ expansion). Interestingly, on the lattice, the chiral Gross-Neveu model appears at a Landau-forbidden second order phase transition separating two distinct and unrelated symmetry-breaking orders. We point out the crucial role of two different 't Hooft anomalies or Lieb-Schultz-Mattis obstructions for this Landau-forbidden phase transition to occur.

description: We consider $5$ dimensional electrostatic solutions to Einstein-Maxwell gravity with $2$ commuting spacelike Killing fields. Taking two distinct reductions from $5$ dimensions to a $3$ dimensional base space, we write the Einstein-Maxwell equations using some axially symmetric functions on $\mathbb{R}^3$. These equations can be viewed as arising from a harmonic map coupled to 3-dimensional gravity with the isometries of the target space of this map revealing a hidden $SL(2,\mathbb{R})$ symmetry of this sector of the theory. Depending on the choice of reduction this symmetry then gives rise to two different 1-parameter families of transformations corresponding to either charging a black hole or immersing it in a background electric field. We use these transformations to charge a static black Saturn and a static $L(n,1)$ black lens spacetime and by tuning the strength of the external field, we cure the conical singularities to give new regular solutions. Notably the electrified black lens generated is the first example of a regular black lens in Einstein-Maxwell gravity with topologically trivial asymptotics.

description: We report experimental measurements of the rates of blackbody radiation-induced transitions between high-lying (n>60) S, P and D Rydberg levels of rubidium atoms in a magneto-optical trap using a hybrid field ionization and state-selective depumping technique. Our results reveal significant deviations of the measured transition rates from theory for well-defined ranges of the principal quantum number. We assume that the most likely cause for those deviations is a modified blackbody spectrum inside the glass cell in which the magneto-optical trap is formed, and we test this assumption by installing electrodes to create an additional microwave cavity around the cell. From the results we conclude that it should be possible to use such external cavities to control and suppress the blackbody radiation-induced transitions.

Emotion regulation in ongoing service relationships: a mixed-method study with aged care employees
Creators: name: Guan, Bichen
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Managing emotions effectively is extremely important in today's workplace. To manage emotional demands, employees use different emotion regulation (ER) strategies which subsequently influence personal and job-related outcomes. Many ER studies have been conducted in short-term service encounter contexts, but researchers have rarely considered the ongoing nature of many service interactions. The processes and outcomes of ER in ongoing service relationships are important to examine, given that such relationships may provide social rewards for employees but also involve unique ER challenges. The thesis examines the processes and outcomes of ER in ongoing service relationships by way of four studies conducted in aged care settings. Aged care employees have repeated interactions and ongoing service relationships with elderly residents and are required to manage a range of emotional demands. In Study 1, to investigate the processes of ER, 42 in-depth interviews were conducted with aged care employees and managers in China. The dynamic processes involved in switching ER strategies under the influence of organizational display rules and employee-client relationships were identified in a filial piety culture. In Study 2, 66 in-depth interviews were conducted with aged care employees and managers in Australia to investigate the impact of relational characteristics on ER. Results demonstrate that whether employees have exchange or communal or hybrid relationships with elderly clients can influence employees' use of ER strategies at work. In Study 3, 336 Australian aged care employees were surveyed to examine the effects of regulating one's own and others' emotions on job burnout and the moderating role that dispositional gratitude plays in the relationships between ER strategies and burnout. Using ER strategies can help employees feel accomplished at work but may deplete emotional resources and lead to emotional detachment with clients. Gratitude acts as a positive personal resource to buffer burnout when employees regulate others' but not their own emotions. In Study 4, 221 Australian aged care employees were surveyed to examine whether dispositional communal orientation influences the use of particular ER strategies and indirectly affects well-being. Results show that communal orientation is negatively related to emotional exhaustion via the ER strategy of reappraisal. Supervisors' expressions of compassion strengthen the indirect effect. Overall, results of this thesis suggest that ongoing employee-client relationships embody norms and expectations around the experience and expression of emotions, and that ER processes, individual affect, and organizational culture are inextricably linked to employee well-being in the workplace.

description: The 8-Pmmn borophene, a boron analogue of graphene, hosts tilted and anisotropic massless Dirac fermion quasiparticles owing to the presence of the distorted graphene-like sublattice. First-principles calculations show that the stacked 8-Pmmn borophene is transformed into the fused three-dimensional borophene under pressure, being accompanied by the partially bond-breaking and bond-reforming. Strikingly, the fused 8-Pmmn borophene inherits the Dirac band dispersion resulting in an unusual semimetal-semimetal transition. A simple tight-binding model derived from graphene qualitatively reveals the underlying physics due to the maximum preservation of graphene-like substructure after the phase transition, which contrasts greatly to the transformation of graphite into diamond associated with the semimetal-insulator transition.

description: Personal data is becoming one of the most essential resources in today's information-based society. Accordingly, there is a growing interest in data markets, which operate data trading services between data providers and data consumers. One issue the data markets have to address is that of the potential threats to privacy. Usually some kind of protection must be provided, which generally comes to the detriment of utility. A correct pricing mechanism for private data should therefore depend on the level of privacy. In this paper, we propose a model of data federation in which data providers, who are, generally, less influential on the market than data consumers, form a coalition for trading their data, simultaneously shielding against privacy threats by means of differential privacy. Additionally, we propose a technique to price private data, and an revenue-distribution mechanism to distribute the revenue fairly in such federation data trading environments. Our model also motivates the data providers to cooperate with their respective federations, facilitating a fair and swift private data trading process. We validate our result through various experiments, showing that the proposed methods provide benefits to both data providers and consumers.

description: The Lorenz system was derived on the basis of a model of convective atmospheric motions and may serve as a paradigmatic model for considering a complex climate system. In this study, we formulated the thermodynamic efficiency of convective atmospheric motions governed by the Lorenz system by treating it as a non-equilibrium thermodynamic system. Based on the fluid conservation equations under the Oberbeck-Boussinesq approximation,the work necessary to maintain atmospheric motion and heat fluxes at the boundaries were calculated. Using these calculations, the thermodynamic efficiency was formulated for stationary and chaotic dynamics. The numerical results show that, for both stationary and chaotic dynamics, the efficiency tends to increase as the atmospheric motion is driven out of thermodynamic equilibrium when the Rayleigh number increases. However, it is shown that the efficiency is upper bounded by the maximum efficiency, which is expressed in terms of the parameters characterizing the fluid and the convective system. The analysis of the entropy generation rate was also performed for elucidating the difference between the thermodynamic efficiency of conventional heat engines and the present atmospheric heat engine. It is also found that there exists an abrupt drop in efficiency at the critical Hopf bifurcation point, where the dynamics change from stationary to chaotic. These properties are similar to those found previously in Malkus-Lorenz waterwheel system.

description: Machine Learning methods can learn how to reconstruct Magnetic Resonance Images and thereby accelerate acquisition, which is of paramount importance to the clinical workflow. Physics-informed networks incorporate the forward model of accelerated MRI reconstruction in the learning process. With increasing network complexity, robustness is not ensured when reconstructing data unseen during training. We aim to embed data consistency (DC) in deep networks while balancing the degree of network complexity. While doing so, we will assess whether either explicit or implicit enforcement of DC in varying network architectures is preferred to optimize performance. We propose a scheme called Cascades of Independently Recurrent Inference Machines (CIRIM) to assess DC through unrolled optimization. Herein we assess DC both implicitly by gradient descent and explicitly by a designed term. Extensive comparison of the CIRIM to CS as well as to other methods is performed: the E2EVN, CascadeNet, KIKINet, LPDNet, RIM, IRIM, and UNet. Models were trained and evaluated on T1-weighted and FLAIR contrast brain data, and T2-weighted knee data. Both 1D and 2D undersampling patterns were evaluated. Robustness was tested by reconstructing 7.5x prospectively undersampled 3D FLAIR MRI data of Multiple Sclerosis (MS) patients with white matter lesions. The CIRIM performed best when implicitly enforcing DC, while the E2EVN required an explicit DC formulation. In reconstructing MS patient data, prospectively acquired with a sampling pattern unseen during model training, the CIRIM maintained lesion contrast while efficiently denoising the images. The CIRIM showed highly promising generalization capabilities maintaining a very fair trade-off between reconstructed image quality and fast reconstruction times, which is crucial in the clinical workflow.

description: This paper deals with the inverse problem of recovering an arbitrary number of fractional damping terms in a wave equation. We develop several approaches on uniqueness and reconstruction, some of them relying on Tauberian theorems on the relation between the asymptotics of solutions in time and Laplace domain. Also the possibility of additionally recovering space dependent coefficients or initial data is discussed. The resulting methods for reconstructing coefficients and fractional orders in these terms are tested numerically. Additionally, we provide an analysis of the forward problem, a multiterm fractional wave equation.

description: Student engagement at university is significantly influenced by sense of belonging. In 2013, our university developed a novel extra-curricular program designed to foster a sense of belonging in students who commute to university – the Monash Non-Residential Colleges (NRC) program. This study examines whether participation in the Monash NRC program changed students’ perceptions about their university experience and their sense of belonging to the university community. We show that our NRC program appears to be effective in fostering a more positive university experience for students when compared with non-NRC students. Additionally, we demonstrate that our NRC program influenced students’ sense of belonging through increased interaction with peers and staff as well as greater reported attendance on campus.

description: Research on the politics of sexuality and the LGBT movement in contemporary Poland tends to overlook the larger socio-economic changes that affect them. Omitting these processes from studies of sexuality, given the profound transformations occurring in Poland over the last two to three decades, produces incomplete accounts. This study builds on the existing knowledge of the politics of sexuality in contemporary Poland and extends it by addressing the question of whether and how processes of neoliberalization matter and how differences of class, gender, and location position subjects differently within the landscape of politics of sexuality. Through a mixed qualitative approach, combining content and discourse analysis with semi-structured in-depth interviews, this project addresses existing empirical and theoretical research gaps. Empirically, it engages with the LGBT movement in general, focusing on two largely unstudied phenomena: Christian LGBT organizing – as exemplified by Wiara i Tęcza (WiT, Faith and Rainbow) – and religiously motivated sexual reorientation therapy, also known as Reparative Therapy (RT). Theoretically, this study explores how processes of neoliberalization collude with existing patriarchal regimes shaping individual subjectivities, but also affecting the kind of politics that are possible both locally and globally. Drawing on the literature on sexuality and capitalism I argue that WiT’s project is best understood through what I term godly homonormativity. My analysis of RT is informed by the literature on psychotherapeutics and how these align with neoliberal ideas of personhood but moving beyond the individual level, I argue that RT should be understood as commodification of homophobia and it must be analyzed in relation to the neoliberal framework that enables it. Finally, I demonstrate that LGBT organizing and RT are classed, localized and gendered and argue that these complex intersections can only be understood by linking them back to the material conditions in which they are produced.

description: Photonically integrated resonators are promising as a platform for enabling ultranarrow linewidth lasers in a compact form factor. Owing to their small size, these integrated resonators suffer from thermal noise that limits the frequency stability of the optical mode to ~100 kHz. Here, we demonstrate an integrated stimulated Brillouin scattering (SBS) laser based on a large mode-volume annulus resonator that realizes an ultranarrow thermal-noise-limited linewidth of 270 Hz. In practice, yet narrower linewidths are required before integrated lasers can be truly useful for applications such as optical atomic clocks, quantum computing, gravitational wave detection, and precision spectroscopy. To this end, we employ a thermorefractive noise suppression technique utilizing an auxiliary laser to reduce our SBS laser linewidth to 70 Hz. This demonstration showcases the possibility of stabilizing the thermal motion of even the narrowest linewidth chip lasers to below 100 Hz, thereby opening the door to making integrated microresonators practical for the most demanding future scientific endeavors.

description: This thesis is an interdisciplinary study of the (homo)sexual narratives that circulate in contemporary British contexts. It draws on three years of ethnographic research in Brixton, South London, centrally analysing in-depth interviews with 19 LGBTQ-identified residents to present a situated interrogation of (homo)sexual progress narratives. The research critically develops feminist and queer theorisations of the role progress narratives play in sexual politics, focusing particularly on the spatial and social imaginaries that are animated in celebrations of sexual modernity. Consequently, the thesis also interrogates the ways in which classed and racialized hierarchies are sustained through everyday attributions of homophobia. In addition, this analysis is brought into dialogue with research on gentrification and territorial stigmatisation to think about the role of sexual progress narratives in contemporary debates on housing and regeneration in London. I draw attention to the imbrication of local, national and transnational discourses in framing both spaces of homophobia, and spaces of sexual tolerance. This thesis argues that the ‘small stories’ made available through situated research should be turned to as a resource for critical theory. I identify and engage narrative techniques including proliferation, layering, periodisation, and fictionalisation, which can be deployed to tell a disorderly story of sexual progress. I suggest that layering these small, disorderly stories not only undermines the amenability of sexual progress narratives and gay rights rhetoric to stigmatisation, but also better reflects the heterogeneous experiences and desires of LGBTQ people. In this way, this thesis examines (homo)sexual progress narratives through new analytical frames, and contributes to scholarship on lesbian and gay politics, ‘gay’ gentrification, and sexual narrative.

description: By expanding the Dirac delta function in terms of the eigenfunctions of the corresponding Sturm-Liouville problem, we construct some new (oscillating) integral transforms. These transforms are then used to solve various finance, physics, and mathematics problems, which could be characterized by the existence of a multilayer spatial structure and moving (time-dependent) boundaries (internal interfaces) between the layers. Thus, constructed solutions are semi-analytical and extend the authors' previous work (Itkin, Lipton, Muravey, Multilayer heat equations: application to finance, FMF, 1, 2021). However, our new method doesn't duplicate the previous one but provides alternative representations of the solution which have different properties and serve other purposes.

description: Polymorphic structures of transition-metal dichalcogenides (TMDs) host exotic electronic states, like charge density wave and superconductivity. However, the number of these structures is limited by crystal symmetries, which poses a challenge to achieve tailored lattices and properties both theoretically and experimentally. Here, we report a coloring-triangle (CT) latticed MoTe2 monolayer, termed CT-MoTe2, constructed by controllably introducing uniform and ordered mirror-twin-boundaries into a pristine monolayer in molecular beam epitaxy. Low-temperature scanning tunneling microscopy and spectroscopy (STM/STS) together with theoretical calculations reveal that the monolayer has an electronic Janus lattice, i.e., an energy-dependent atomic-lattice and a pseudo-Te sublattice, and shares the identical geometry with the Mo5Te8 layer. Dirac-like and flat electronic bands inherently existing in the CT lattice are identified by two broad and two prominent peaks in STS spectra, respectively, and verified with density-functional-theory calculations. Two types of intrinsic domain boundaries were observed, in one of which the electronic-Janus-lattice feature maintains, implying potential applications as an energy-tunable electron-tunneling barrier in future functional devices.

urn:lsid:zoobank.org:act:A4C333D3-5FA9-4E97-AC05-30944A753528
Type species: Dermatopelte budensis Erdős & Novicky, by monotypy. Erdős, 1951: 175.
Diagnosis. Antenna with 1 anellus, 4 funiculars, and 2 clavomeres (despite sometimes appearing to have 3). Mandibles not meeting medially, lacking teeth, with a row of setae along middle of exterior surface; malar sulcus present; gena concave along malar space; occipital carina absent. Notauli complete; submedian grooves of mesoscutellum present or vaguely indicated by carinae. Propodeum with median carina having an anterior split that is as broad as metascutellum; without plicae; postspiracular furrows crossed by carinae. Petiole longer than broad, dorsally with raised sculpture.
Biology. The only Palearctic species of Dermatopelte, D. budensis, is an ectoparasitoid of Zygaena species (Askew et al. 2008). Hosts of Indo-Malayan and Nearctic species are not known. Zygaena does not occur in those realms, but species of the zygaenid subfamily Procridinae occur in the both realms and Chalcosiinae occur in the Indo-Malayan realm.
Distribution. Indo-Malayan, Nearctic, and Palearctic.
Etymology. The original authors explain that the name is derived from the Greek nouns τό δέρµα (to derma) and ἡ πέλτη (hē pelte). Because ἡ πέλτη is feminine, we conclude that Dermatopelte is feminine in gender.

description: We present an analytical solution for the magnetic field of a homogeneously magnetized cylinder tile and by extension solutions for full cylinders, rings, cylinder sectors and ring segments. The derivation is done by direct integration in the magnetic surface charge picture. Results are closed-form expressions and elliptic integrals. All special cases are treated individually, which enables the field computation for all possible position arguments. An implementation is provided in Python together with a performance analysis. The implementation is tested against numerical solutions and applied to compute the magnetic field in a discrete Halbach cylinder.

description: When performing an aggregate data meta-analysis of a continuous outcome, researchers often come across primary studies that report the sample median of the outcome. However, standard meta-analytic methods typically cannot be directly applied in this setting. In recent years, there has been substantial development in statistical methods to incorporate primary studies reporting sample medians in meta-analysis, yet there are currently no comprehensive software tools implementing these methods. In this paper, we present the metamedian R package, a freely available and open-source software tool for meta-analyzing primary studies that report sample medians. We summarize the main features of the software and illustrate its application through real data examples involving risk factors for a severe course of COVID-19.

description: A tidal disruption event (TDE), AT2019dsg, was observed to be associated with a PeV neutrino event, IceCube-191001A, lagging the optical outburst by a half year. It is known that TDEs may generate ultrafast outflows. If the TDE occurs in a cloudy environment, the outflow-cloud interactions may form shock waves which generate accelerated protons and hence delayed neutrinos from hadronic interactions in clouds. Here we investigate the neutrino production in AT2019dsg by examining the TDE outflow-cloud interaction model. We find that, for an outflow with a velocity of 0.07c and a kinetic luminosity of $10^{45}\rm erg\ s^{-1}$, protons may be accelerated up to $\sim$ 60 PeV by the bow shocks, and generate PeV neutrinos by interactions with clouds. The predicted neutrino number in this model depends on the uncertainties of model parameters and in order to match the observations, some challenging values of parameters have been involved. The PeV neutrino event number can be $\sim 4\times10^{-3}$ for a hard proton index $Γ=1.5$.
